Tips To Reduce Pesticides In Your Produce
Eating fruits and vegetables, whether organic or conventional, far outweighs the risks of the pesticides they may contain. That said many of us still want to minimize our intake when possible. Even if you don’t have the luxury of buying organic foods there are things you can do at home to help reduce your intake of pesticides in the produce you purchase. Tips to Reduce Your Intake of Pesticides From That National Pesticide Information Center1 To avoid exposure to a single pesticide make sure to include a variety of fruits and vegetables in your diet. Thoroughly wash all produce whether it has a peel or is labeled organic. To avoid pesticides sticking to produce, wash under running water instead or soaking or dunking it. Air or spin produce dry or wipe with a paper towel or clean cloth towel when possible. Scrub firm fruits and vegetables like melons and root vegetables Remove the outer layer of leafy vegetables, such as lettuce or cabbage. Peel fruits and vegetables when possible. To avoid residues that might accumulate in the fat of animal protein, trim fat and skin from meat, poultry, and fish. If intake of fruits and vegetables is low, consider supplementing with purified polyphenol extracts that have minimal pesticides. Ranking of Pesticides in Fruits and Vegetables2 The Environmental Working Group is an organization that has created a ranking system of fruits and vegetables based on their likelihood of being contaminated with the highest levels of pesticides. The ranking is established after the fruits and vegetables have been washed or peeled. The top offenders include those that have soft skins because they are more likely to absorb pesticides, which they term the “Dirty Dozen”. If you already purchase some organic produce or are thinking about making the switch, buying organic based on the Dirty Dozen list might be a good place to start. Here is the 2021 list. This year’s "Dirty Dozen" includes: Strawberries Spinach Kale, collard and mustard greens Nectarines Apples Grapes Cherries Peaches Pears Bell and hot Peppers Celery Tomatoes The good news is that there are a good number of non-organic fruits and vegetables without high levels of pesticides. Since many fruits and vegetables have peels, they offer a higher level of protection, which have been dubbed the “Clean 15” since they have little to no pesticides. This year's "Clean 15" includes: Avocados Sweet corn* Pineapple Onions Papaya* Sweet peas (frozen) Eggplant Asparagus Broccoli Cabbage Kiwi Cauliflower Mushrooms Honeydew melon Cantaloupe Click Here to Download Your Easy Produce Shopping Guide References: Shoppers Guide to Pesticides and Produce. https://www.ewg.org/foodnews/full-list.php.

Packing For A Day On The Go
There are so many things that can stand in the way of good health, but often the difference between failure and success is whether you plan ahead. If you have a full day of meetings on the road, are taking a weekend road trip, or doing a beach day, here are ideas of what you can bring while staying in the Zone. Now if a meeting runs over, there are no healthy options along the way, or the lines are too long to stop, you have everything you need on hand. Protein Ideas Greek Yogurt: Easy to bring on the go if you have ice packs. Some individual containers have up to 20 grams of protein per serving. Jerky: There are so many varieties and high-quality brands out there. They are a bit higher in sodium and some have sugar so do pay attention to labels and portions. String Cheese: Easy on-the-go choice and having them pre-packaged keeps portion in check. Couple with a piece of fruit and you have the ideal zone snack. Hard-Boiled Egg Whites: Eggs are considered a high biological value food, meaning they contain all the essential amino acids your body needs. To reduce the saturated fat in the yolk, swap it out with healthier fats like hummus or guacamole for an easy snack. Just don’t pack and forget about them please! Chicken or Tuna Salad: Left-over chicken or canned tuna makes for a great protein choice. Swap the mayo for Greek Yogurt to make a healthier alternative. Deli Rollups: Wrap lean deli meat in romaine lettuce leaves for an added crunch without the added carbs of bread. Edamame in Pods: These can be found in the freezer section. Place in a baggie in the morning and pending when you eat they’ll be thawed while helping to keep some of your other things on the cooler side. A ½ cup of pods supplies 10 grams of protein, 4 grams of net carbs, and 3.5 grams of fat. A little low on the carbs but pretty close to being Zoned. Healthy Carbs Veggie Sticks: Cut up cucumbers, peppers, radishes, and cherry tomatoes make for a filling snack plus they can be hydrating too. Make them even yummier with a side of dip, hummus, or guacamole. Fruit: Aim for fruits that travel well like Clementines, oranges, apples, or pears. Homemade Chickpeas: If you need a crunchy snack roasted chickpeas are it. Simply drain and rinse the chickpeas, pat dry, lay on a sheet pan, and drizzle with olive oil and seasonings of your choosing. Bake at 425 for 30 minutes (turning halfway through to ensure they don’t burn). Low Carb Tortillas: These are a better alternative to bread just make sure to read the carb amounts on the label. Fat Hummus: There are so many varieties of hummus available which makes it great as a dipping option for veggies on the go. Some also come in convenient single-serve packs which is a great way to bring it while keeping portions in check and avoiding waste. Again just pay attention to portoins as one single-serve might be your whole fat requirement for a meal. Guacamole: Guacamole is rich in heart-healthy fat making them a great option for dipping or spreading. Look for the guacamole minis but keep an eye on the amount of fat in a serving. Nuts: There are so many flavors and varieties in the marketplace now. Try and keep it simple by looking for ones that have just a couple ingredients on the Nutrition Facts Panel. Beware of portions as even a small bag can be up to 3 servings and that is easy to consume in one sitting or on a long drive. Seeds: Pumpkin and sunflower seeds are a moderately good choice and they do contain some protein. Use in moderation as they are high in omega-6 fats (more pro-inflammatory). Plus, they can easily rack up the calorie count of your meal. Combo Foods: If you don't have time to calculate just remember to have your meals and snacks on the go be a blend of protein, healthy carbs, and fat. The following are just an idea of a few pairings. Put them in a mason jar and bring them on the go for an easy meal. Greek Yogurt and Berries topped with a little Zone Cereal Mixed Greens, Tomatoes, Basil, Mozzarella Balls, Precooked Chicken with Vinaigrette Overnight Steel Cuts Oats with Berries and Protein Powder ZoneRx Shakes: 1 scoop of powder with 10-12 ounces of lactose-free milk and mix. A great on-the-go option with the right balance of macros, and no need to think. Zone Protein Bites- An easy and delicious make-ahead snack! Click here to view the recipe. These are just some simple tips to keep you in the Zone all day long! Let us know which ones are your favorites or how you plan ahead for a day on the go in the comments below.
Burn Fat Faster
Now that the Covid-19 epidemic seems to be slowing down, we must contend with the other epidemic that shows no signs of abating. That is our obesity epidemic. If you have excess body fat, you are already inflamed. That excess adipose tissue is the staging area for ongoing inflammatory attacks on every organ in the body. It is also the first sign that your metabolism is becoming dysfunctional, thus reducing your ability to burn excess stored fat for energy. Metabolism is defined as those complex processes that take place in your body to keep you alive. Metabolism allows you to breathe, digest food, circulate blood, keep the brain working, fight infections, and so on. All these processes require massive amounts of ATP. The “traffic cop” that controls your ability to convert stored body fat into ATP is called AMPK. AMPK can be considered the “master switch” of metabolism. If AMPK is optimized, you can burn stored body fat faster to make greater amounts of ATP. Conversely, if AMPK is inhibited, you accumulate incoming calories as excess body fat. Losing excess body fat is a challenge but keeping the excess body fat from returning is even more difficult because your metabolism slows down after losing any bodyweight. The good news is that AMPK activity is under robust dietary control. The best way to optimize AMPK activity is following the Zone Pro-Resolution Nutrition program. By following the anti-inflammatory Zone diet, you can constantly activate your AMPK while reducing calorie intake without hunger or fatigue. Adding omega-3 fatty acids and polyphenols as dietary supplements will also increase AMPK activity through different pathways. Although any one of these three nutritional interventions is good, when you combine all three, they are synergistic, as I describe in my latest book, The Resolution Zone. On the other hand, AMPK activity is inhibited by consuming either excess dietary calories or excess glucose. If you inhibit AMPK, then incoming calories easily get converted and stored at excess body fat. Activating AMPK is the biological key that allows you to burn fat faster and prevent its return. It’s also totally under your dietary control. Once you master these basic dietary concepts of the Zone Pro-Resolution Nutrition program, burning fat faster becomes a lifetime reality that leads to a longer and better life. Additional benefits from activating AMPK will be slowing down your rate of aging and improving the efficiency of your immune system. This is the real reason why you want to be in the Zone.
Stress and Omega-3 Fatty Acids
It’s common knowledge that stress can be a killer. But what is not clear is why is it harmful and what you can do to reduce it? A new research article provides more insight into both questions (1). The subjects in this study were middle-aged, overweight healthy adults. Thirty days before the trial, the subjects were split into three groups consuming either placebo capsules, 1.25, or 2.5 grams of EPA and DHA daily. The stress they were exposed to was being given 10 minutes to prepare a 5-minute speech. This speech entailed telling why they were the best candidates for a job. Furthermore, the speech was delivered in front of two live judges wearing white lab coats who were told to keep neutral facial expressions during the speech. The subjects couldn’t use any notes for their job interview speech in front of the judges. If they didn’t use their allotted 5-minute time, they were told to continue speaking until their five minutes were up. If that wasn’t enough stress, they also had to immediately do an oral 5-minute serial subtraction test after their speech before the same judges. If they made a mistake, they would have to start over from the beginning. This test is known as the Trier Social Stress Test, which produces stress and inflammation (2). About one and half hours before this stress test, the subjects had their blood drawn for cytokine levels and saliva for cortisol levels. Then, they ate a standardized breakfast and then answered a questionnaire on their current state of anxiety. After the 20-minute stress test, the same parameters were measured several times over the next two hours. What happened? Quite a lot. Those taking the 2.5 grams of EPA and DHA per day had significantly lower cortisol levels during and for the next two hours after the test. They also had lower pro-inflammatory cytokine levels and less inhibition of the telomerase enzyme activity that repairs damage to your DNA caused by stress. Similar results of lowered cytokine levels were found in a study of elderly, obese healthy adults taking 2.5 grams of EPA and DHA per day (3). So, what are the implications? If you are in a high-stress occupation, then taking adequate daily levels of EPA and DHA can be your best defense against the inflammation and damage to your DNA that comes with that occupation-induced stress. This group would also include elite athletes who live in a world of constant stress due to training and competition. However, most of us live with chronic low-level stress. The impact of this type of stress on the immune system is the same. It is unlikely that stress will be eliminated in our lives. Still, you can significantly reduce the inflammatory and genetic consequences of that stress by taking adequate EPA and DHA levels on a lifetime basis. References Madison AA et al.

Meal Planning Benefits
There are two types of people, those who know what they’re eating for their next meal and those who figure it out the hour before. Where do you fall? If you tend to wing your weeknight meals, the thought of meal planning can seem daunting. Finding time to sit down and write out your menu for the week, making a list, shopping for ingredients, and then the actual meal prep can seem like a lot. The reality is that all this upfront planning actually saves you time and money, helps with weight control, and is good for your health. Here’s why. The Benefits of Meal Planning 1) Saves You Time and Money: When you go to the store without a plan you spend more money. The reason is you are more likely to overbuy which leads to food waste. How many times have you done the refrigerator cleanout before trash night and the wilted produce, the questionable meat, and the leftovers all end up in the trash? Did you know that the average household wastes almost 32% of its food each year? 1 That is a substantial amount of your income! Meal planning can also save you time and money by helping you avoid takeout when you're time-crunched or those trips to the store for missing ingredients where you end up spending more on things you don’t need. 2) Helps with Weight Control: It is well established that making your own meals helps with weight control. A recent study showed participants in a 40-week Weight Loss Program who frequently planned their meals lost more weight than those who did not2. Another study showed women who meal plan are less likely to be overweight and men and women who plan are less likely to be obese3. Meal planning gives you greater control over the ingredients you use and their healthfulness. Unlike eating out, when you eat at home you have a better sense of your portions and how much you consume. Where eating out often comes with extra sugar, sodium, and fat, when you cook at home there are no hidden ingredients. 3) Makes You More Successful with Your Health Goals: With any goal having a plan makes you more likely to stick with it and succeed. Meal planning goes beyond weeknight meals to include being prepared for those times you might get tripped up. If a meeting goes late, sports go into the evening, or you get stuck on a call, having healthy foods prepped in the fridge, in your purse, or at your desk ensures you have what you need to succeed. Meal planning is associated with a healthier and more varied diet3. 4) Reduces Stress: Meal time can feel stressful and not knowing what you have on hand, especially if you have people in your household that rely on you for meals, can put the pressure on. Planning ahead reduces stress and then when the questions start to roll in about what’s for dinner, you can say what you are having with confidence and start delegating on how everyone can help.

Zone Diet: Everything You Need to Know
Starting a new eating plan or trying to reign in poor eating habits can feel daunting. The beauty of the Zone Diet is whether you are starting, need a diet refresh, or want more convenience, we have you covered. Get a sense of what the diet is all about with our macro guide. This will tell you the types of proteins, carbohydrates and fats that are ideal in the Zone. Want to know exactly what you can have and how much? Try the food block method or counting macros. Both approaches give you the tools to know how to eat in the Zone while teaching you how to incorporate all your favorite foods too. If fast and convenient is your speed, Zone Foods take the thinking out and make meal prep easy. See what method works for you. Pick What Works For You No matter which approach you choose to get you to the Zone you'll always end up in the same place. It really comes down to how much time you want to spend and how precise you want to be. A perfectly balanced Zone meal should control hunger and fatigue for 4-5 hours. The Macro Guide Committing to an eating plan can be overwhelming at first. Why not see if you like the foods and how you can adapt it to what you are already eating. Our macro guide gives you a brief tutorial on the Zone Diet along with a list of the protein, carbohydrate and fat choices that are most ideal in the Zone. Hand-Eye Method The hand-eye method becomes very helpful when you're at a buffet, eating in restaurants, having a catered work lunch, or going to a get-together with friends. All you do is simply divide your plate into three equal sections. On one-third of the plate, you put low-fat protein about the size and thickness of the palm of your hand. The other two-thirds should be filled with colorful carbohydrates, primarily non-starchy vegetables with limited fruits. Finally add a drizzle/dash of monounsaturated fat (olive oil, nuts, avocado) to complete the meal. Counting Macronutrients Using an app to log your foods already? No problem! Fitness apps like myfitnesspal or Lose-It allow you to plug in your macros for a meal or the whole day. This is a great option if you don't want to spend too much time calculating. It allows you to use food labels or tally the totals from each meal to gauge whether you’re in the Zone. If you are calculating total calories as a percent, aim for about 40% of calories from carbohydrates (non-starchy is most ideal), 30% from lean protein, and 30% from heart-healthy monounsaturated fat. Each meal is about 350-400 calories, at least 25 grams of lean protein, less than 12 grams of heart-healthy fat, and about 35 grams of net carbs (total carbohydrate minus fiber). The carbohydrates you choose should come primarily from low-glycemic choices like those in non-starchy vegetables. Zone Food Blocks If you are someone who likes to be as precise as possible, an athlete, or have a defined health goal, counting your macros (protein, carbs and fat) with Zone Food Blocks is the most precise way to get to the Zone. This even gives you an idea of how to fit the occasional indulgence in so you can still stay on plan and not overdo it. If you haven’t already done so, enter your measurements into our Body Fat Calculator. Your results from the Body Fat Calculator will include how many Zone Blocks you should consume. Our Food Block Guide will help you assemble meals and snacks that fit your lifestyle. Zone Foods Zone Foods were designed for those looking for easy ways to get to the Zone with minimal effort. Each Zone food has the balance you’ve come to expect from Zone plus they’re convenient, nutritious, easy to prepare, and taste great Other Helpful Tools: 7 Day Zone Diet Meal Plan How do you Zone?

Olive Oil Benefits
Olive oil has been prized for thousands of years for its health benefits. As to why remains a more open question. As a source of polyphenols, extra virgin olive oil is relatively low compared to berries and other sources of polyphenols like unrefined cocoa powder, as shown below: Polyphenol source amount per 100 g increase in polyphenols compared to olive oil. The numbers above indicate that when comparing the identical weights of various food sources, berries contain four to ten times more polyphenols than extra virgin olive oil. Unrefined cocoa powder contains more than 100 times the polyphenol levels compared to the same weight of olive oil. So, maybe it is not the polyphenol content that counts for the touted health benefits of extra virgin olive. If not, then what else might be in extra virgin olive oil? I believe the answer is the unique anti-inflammatory phenols contained in extra virgin olive oil. A little terminology is always helpful. A polyphenol is defined as containing two or more phenyl groups in a molecule. A phenolic compound has only one. Furthermore, most polyphenols are composed of polymers that are not absorbed, whereas a phenolic compound contains only monomers easily absorbed. There is nothing magical about a phenol group per se since benzene has a single phenyl group, and no one touts the health benefits of consuming benzene. It is the structure of the phenolic compounds that make extra virgin olive oil so unique. Here they are shown below: The first two compounds are tyrosol and hydroxy-tyrosol which are potent anti-oxidative compounds (1,2). The third structure is oleocanthal which has anti-inflammatory properties (3). To be correctly termed as a polyphenol means the compound must contain at least two phenyl groups, and none of the active compounds in extra virgin olive oil meets that criteria. For comparison, I have enclosed the structure of a true polyphenol with three phenyl groups. This specific polyphenol (a delphinidin) is found in blueberries, maqui berries, red wine, and black beans. Unfortunately, most of the delphinidins and other polyphenols found in fruits and vegetables are in the form of polymers. As a result they are poorly absorbed into the blood. It is only chromatographically purified extracts of the maqui berry that you will find delphinidins as monomers. That is why the polyphenols found in purified maqui extract are highly bioavailable, just like the phenolic compounds found in extra virgin olive oil (4). If the active ingredients don’t get into the blood, they will not do you much good. Getting back to extra virgin olive oil, what you are looking for is the levels of phenolic compounds, not the polyphenols. Most marketers of olive oils don’t have a clue what those levels are because they are challenging to analyze. We are currently doing 3rd party testing on the Zone Extra Virgin Olive Oil batch we just received from Italy and plan to post the results shortly. Even though its hard to test these compounds, one easy way to know it's a quality oil and contains phenolics is the cough test. Take about one teaspoon of extra virgin olive oil and put it on the tip of your tongue. It should taste like melted butter. The lack of any bitter taste indicates low levels of free fatty acids. Then use your tongue to flip it to the back of your throat. If it contains high levels of phenolic compounds, you will get a coughing response. The greater number of coughs you get from this test, the higher the levels of phenolic compounds. This simple test is why Italians refer to a “two-cough” extra virgin olive oil as their standard of excellence, not the total levels of polyphenols. The Zone Labs Organic Extra Virgin Olive Oil is a “two-cough” oil. References 1.

Extra Virgin Olive Oil: Q/A Video with Dr. Sears
Extra virgin olive oil (EVOO), not refined olive oil, is one of the richest of all oils in terms of polyphenols. In this video Dr. Sears discusses why he considers EVOO one of the best oils out there, how it compares to other oils in the consumer marketplace, the health benefits, and how to pick a quality oil. See what he has to say.
Allulose: A Natural Sugar for Better Glycemic Control
One of the critical factors for the success of the Zone diet is improved glycemic control. This concept simply means that blood sugar levels are more stabilized from one meal to the next. The benefits are lack of hunger, better mental cognition, and reduction of inflammation. For decades, the diabetic research community has known that fructose has been the ideal simple sugar for better glycemic control. The reason is that fructose has a glycemic index that is five times lower than glucose. Consequently, this means less glucose enters the blood, and the result is better hormonal control. Part of the reason is that much of the dietary fructose never reaches the blood because bacteria metabolize it in the gut. That’s why I have always used fructose as a primary carbohydrate in Zone bars and shakes. It just makes scientific sense. Unfortunately, like politics, science is also prone to social media. In 2004, a short letter was written observing a correlation in the rise of obesity with the increase of high-fructose corn syrup (1). Keep in mind that high-fructose corn syrup is about 50 percent fructose and 50 percent glucose which is virtual identical to the composition of table sugar. Then came several popular diet books such as Fat Chance claiming our obesity epidemic is caused by fructose (2). One problem with that theory is that fruits are rich in fructose, and no one has ever advocated the stopping of fruit consumption. Another problem with that theory is that high-fructose corn syrup consumption peaked in 1999 and has declined by 40 percent since that time (3). Today the consumption of high-fructose corn syrup is below the level it was in 1990, and our obesity epidemic continues to increase. Rather than cursing the darkness of quasi-scientific misinformation, the best policy is to embrace new science. Now an alternative sweetener has come to market that might have even better glycemic properties than fructose. That’s why I am excited about allulose. Allulose is a natural sugar found in low quantities in various fruits. What is unique about allulose is that 90 percent never enters the blood and thus goes directly to the colon to improve gut health. Consequently, the FDA doesn’t consider allulose to be a sugar because it is not absorbed, but the FDA also doesn’t treat it as a fiber. It's like a “phantom” carbohydrate. However, what it does do in the gut is to increase AMPK levels (4). One of the consequences of activating AMPK is that you live longer (5). Thus, allulose can be considered an “anti-aging “sugar. Now that allulose can be produced in large amounts by biotechnology, it has been recently granted Generally Regarded as Safe (GRAS) status meaning it can be incorporated into food products. This opens up an entirely new potential for our next generation of Zone shakes and bars for enhanced glycemic control. For example, with the replacement of fructose by allulose in our ZoneRx shakes (currently available in Chocolate and Vanilla), the decrease in total carbohydrates now allows for the addition of extra berries to each shake to achieve a truly Zone balance. The amount of berries we recommend for better glycemic control is based on science not guessing. I recommend adding two blocks of berries (strawberries, blueberries, raspberries, or blackberries). That is also about 1 cup or about 6 oz of berries. This amount adds even more polyphenols and fermentable fiber to the final ZoneRx shake while maintaining the Zone macronutrient balance needed for optimal hormonal control. Of course, it also makes a complete meal that tastes likes a gourmet dessert in seconds. For maximum convenience, just purchase frozen berries (they have a higher nutrient quality than fresh berries) and keep enough already thawed in the refrigerator to make about two Zone shakes. As the leader in nutrition for the last 30 years, we are the first company to have shakes using allulose. Our ZoneRx bars containing allulose are under development and will be available shortly. The more science we can bring to your kitchen, the easier it becomes to retake control of your health by being in the Zone.

Milk and Dairy: Good or Bad For Health?
Since February was heart month, I thought it worthwhile to discuss the relationship between milk and heart health. Dairy milk consumption in the US has decreased by 40% since 1975, but total dairy consumption (milk, cheese, yogurt, and butter) has never been higher. As an example, cheese consumption is up by about 160% since 1975. Furthermore, while dairy milk consumption is decreasing, plant-based “milk” consumption is increasing. It started with soy milk (too beany), then coconut and almond milk (deficient in protein), followed by rice, oat, hemp, and more increasingly exotic plant-based “milk” products. Why? It beats me. Dairy milk is probably the most inexpensive, high-quality protein source (only egg whites have a higher protein quality). Milk also contains calcium, magnesium and potassium, and Vitamin D. So, what’s the problem? A recent study in the British Journal of Nutrition may help explain the controversy (1). The largest consumers of dairy products in the world are the Finnish. When they analyzed collected data over a nearly 30 year period and then made all the appropriate adjustments to the raw data, they found that fermented and non-fermented dairy products had opposite associations with the risk of developing heart disease. Those consuming fermented dairy products had a 26 percent lower risk of Coronary Heart Disease (CHD), and those consuming non-fermented dairy products had a 43 percent greater risk of CHD. Furthermore, in the fermented dairy group, the lower the fat content (less than 3.5 percent fat), the less CHD they developed. When you ferment dairy products, you are removing lactose. Dairy milk is about 5 percent lactose. To make yogurt, you add bacterial cultures that break some of the lactose into glucose and galactose. The amount of lactose in yogurt is about 4 percent. When you make cheese, the process is more complicated. First, you start by adding a bacterial culture to pasteurized milk to reduce the initial lactose levels. Then you add rennet, a combination of proteases and lipases. Rennet is the dried inner lining of the fourth stomach chamber of young calves (a byproduct of veal production) to curdle the milk's casein protein. This natural form of rennet is the preferred choice for high-quality cheeses. For more mass-produced cheeses, they use enzymes derived from molds. Whatever the source of rennet, the addition of rennet makes curds leaving much of the lactose and whey protein in the solution. The milk curds are collected and then aged to either make soft cheeses (about 2% lactose) or hard cheeses (about 1% lactose). Okay, but what about the reports of associations of dairy milk consumption and increased IGF-1 levels? IGF-1 is a growth factor that might be associated with breast cancer (2). A recent observational study suggested a potential linkage between IGF-1 and breast cancer (3). However, an earlier study suggested the opposite conclusions (4). The controversy may be related to the fact that non-fermented dairy products increase IGF-1, whereas fermented dairy products don’t increase IGF-1 levels (5). Reducing cancer risk using fermented dairy products is also suggested by a recent meta-analysis (6). In this era of conflicting claims of dairy products and chronic disease, it seems your best bet is to remove as much of the lactose from dairy products that you possibly can and still retain all of the nutritional benefits found in dairy products. The best high-tech way is to make completely lactose-free milk by treating the dairy milk with the enzyme that breakdowns down the lactose into glucose and galactose. Now you have entirely lactose-free dairy milk with all the benefits of inexpensive, high-quality proteins and associated vitamins and minerals. This elimination of lactose is why all of our products either use lactose-free dairy protein or recommend using lactose-free milk in our ZoneRx shakes. To paraphrase Neville Chamberlain, it brings dietary “peace in our time” as well as better health. Let us know your stance on dairy in the comments below. References 1. Koskinen TT et al.

Cocoa Benefits: 5 Things You May Not Know
We often hear about the benefits of eating chocolate but do you know what makes it healthy? Hint, it’s all about the cocoa! Here are five benefits you may not know about cocoa and why it pays to be choosy with what you pick. Cocoa is rich in a group of naturally occurring compounds called polyphenols. Polyphenols are known for their anti-oxidant and anti-inflammatory properties. While a variety of polyphenols exist in cocoa, the primary polyphenols come from a group called flavanols. It is these polyphenols that are responsible for the health benefits we often attribute to chocolate. What you may not know is that the polyphenol content of cocoa can fluctuate greatly. It largely depends on the type of bean, where it is grown, and other factors like the temperature used in processing or potential use of alkali treatment on the cocoa powder. It has been shown that as much as a three-fold difference can exist in total polyphenol content depending where it is grown. Although 30% of the worlds cocoa is produced in the Ivory Coast, the plants with the highest polyphenols are actually grown in the highlands of Ecuador. Studies show that cocoa helps with the expanding the blood vessels, also called vasodilation. This makes blood move more easily throughout the body. The European Commission has approved the health claim that 200mg of cocoa flavanols from either cocoa beverages or dark chocolate daily helps contribute to normal blood flow.Cocoa supports a healthy gut by promoting the levels of beneficial bacteria. The gut has one of the highest populations of bacteria in the body. Some of these bacteria can be a significant source of inflammation. Cocoa's anti-inflammatory properties help combat this inflammation since most cocoa polyphenols are not absorbable in the blood and end up in the gut.Building on the improved blood properties of cocoa, intervention studies suggest that cocoa benefits the heart by helping to reduce blood pressure, improve vascular function, and help support healthy blood sugar by reducing insulin resistance (1).Since cocoa has anti-oxidant and anti-inflammatory benefits, research suggests this could aid your workouts. Taking cocoa flavanols with exercise has been shown to improve vascular function, reduce exercise-induced oxidative stress and even alter how the body uses carbohydrates and fats during exercise (2). The benefits of cocoa are well researched but before you start thinking about all the places you can add cocoa into your day, here is what you to need to know. Cocoa is naturally rich in the heavy metal cadmium so the higher the concentration of cocoa polyphenols, the higher the amount of cadmium. Why cadmium is dangerous is because it can cause kidney and liver toxicity and inhibits the activity of critical anti-oxidative enzymes (3). This is also why many chocolate products rich in cocoa polyphenols exceed the daily limits for cadmium set by the state of California (3). So how do you get the benefits of cocoa without the cadmium…you look to Dr. Sears. How CacaoRx Came To Be Dr. Sears knew the literature was well documented on the benefits of cocoa for its polyphenol content and improved blood flow properties, but he had to solve for the issue with cadmium. This led him to create a proprietary purification process and ultimately the creation of CacaoRx. The result is the highest concentration of cocoa polyphenols with the lowest levels of cadmium. This is why we post the polyphenol and heavy metal content for each lot of our cocoa polyphenol concentrates so that you can see it meets his incredibly high standards. This purification process then led him to seek regulatory approval so that the cocoa could be used as a food products (a.k.a. Generally Regarded As Safe (GRAS) status) such as our ZoneRx bars and shakes. Now you can get all the great benefits of cocoa polyphenols without worrying about cadmium, because they were created with Dr. Sears' continuing commitment to product excellence. References: 1.

Healthy Habits for Weight Loss
Turning the page on a new week, new month or new year brings hope, a sense of new beginnings and a fresh start. No matter where you begin, be realistic with yourself. Setting lofty goals or intentions is like trying to get the perfect photo to post on social. Just like you rarely get everyone smiling on the first try, it takes several attempts to get it right, requires work, and sometimes it’s just not realistic. The best way to be successful with your goals is building on what you’re already doing right now, no matter how big or small, and determining what tools you have and need to get you there. This will create habits that stick and make your goals more attainable. Here are some ideas for small things you can do or add into your weekly routine to keep up the healthy habits you’re trying to achieve in 2021. Define Your Goals and How You Plan To Reach Them: Saying you want to lose 10lbs could be a realistic goal, but your success will depend on your plan to get there. Ask yourself what you need to do to reach your goal; whether its logging meals daily, grocery shopping every Sunday, meal planning, enlisting the support of family, establishing an exercise routine, and/or weekly food delivery. Write down the tools you have and the ones you need to succeed. Each week evaluate what’s working, what’s not, and where you can improve. Make Time For Your Priorities: It’s easy to have the best intentions going into the day and then have it spiral out of control with meetings, appointments, or things you hadn’t planned. Getting up early to either prep your meals or workout is a great way to set the day up for success. Not a morning person? Schedule your calendar at the start of the week based on when you want to shop, meal prep, menu plan, or workout. When its already built into your schedule you’re more likely to have it stick. Remember there is always time for the things you prioritize. Try A New Recipe Each Week: If 2020 was the year you ate out less and cooked more at home, build on this healthy habit. Break up the monotony of your weekly meals by incorporating one new meal into your repertoire each week. This is a great way to add more variety to your meals, spice things up, make them healthier and try new things. If you can’t eat out with family and friends why not make this a social event and pick a recipe with a friend or family member and make it together virtually. Move More: A study recently published in the Annals of Internal Medicine confirmed that globally overall activity levels declined during the pandemic (1). Even if you’ve continued to workout, chances are your overall lifestyle activity has declined due to running less errands, working remotely, and trying to streamline your daily activities to minimize exposure. Try and get short bursts of activity wherever you can such as walking the stairs in your house every hour, taking a walk around the neighborhood a few times a day, or bring a little extra fire and intensity to the workouts you’re already doing. Declutter Your Kitchen: One of the biggest things working against you could be your environment, especially if you’re still working remotely or spending more time at home. Studies show that individuals eat less when they’re in an environment that is less cluttered and less chaotic. Declutter your countertops, keep healthy foods in your line of vision, keep processed foods out of reach or avoid buying, and make sure to keep your pantry and fridge stocked with easy to grab healthy options like nuts, Greek yogurt, cheese sticks, fruit, hummus, or veggies. Don’t Ditch the Carbs, Swap Them: Processed carbohydrates (breads, pastries, cereals, starchy snacks and sweets) are convenient, but the calories can add up quick. Replacing simple carbs with those rich in fermentable fiber like vegetables and fruit improves the release of hormones in the gut tied to satiety. These hormones send signals to our brain staying stop eating. Just remember to increase your intake of fiber rich foods slowly and consume more water when you do. This will improve digestion and keep everything moving. Evaluate Your Relationship With Alcohol: Maybe the idea of Sober January wasn’t a bad one. Alcohol consumption has drastically increased over the past year with heavy drinking (more than 4 glasses) in women spiking 41% (2). Alcohol can wreak havoc on our mood, energy, activity level, and relationships making little to no alcohol the ideal choice. Evaluate your relationship with alcohol and if it might be time to change the frequency of your consumption. Show Some Gratitude: One thing we learned in 2020 is gratitude and to not take things for granted. Having gratitude and expressing it in small ways can promote feelings of happiness, decrease stress, and improve mental well-being. This could be done through writing notes of appreciation, verbalizing thank you’s or writing down what we’re grateful for daily. The goal is to focus on what you have, not what you lack which promotes greater satisfaction and happiness (3). Check out our daily gratitude journal here. As we kick off 2021 with our hopes of a fresh start, make sure to give yourself credit for all the positive things you did for your health in 2020. Build on these positive behaviors, congratulate yourself when you hit milestones, and don’t be hard on yourself if you slip up. Set realistic and achievable goals and we know this will be your best year yet. Remember that no matter what your health goals are this year that we’re always here to help!
