Dr. Sears Answers Your Questions On Protein and Protein Powder
The global market for protein supplements is anticipated to rise 8.5% by 2030. This increased demand is widely due health-conscious individuals, fitness go-ers, and millennials looking to add more balance to their diets. In this blog, Dr. Sears covers some basic questions on protein and then gets into protein powders and what you need to know. Q. How much protein do you need each day? A. It depends on your lean body mass and your level of physical activity. The reason you need protein is to maintain and repair damaged muscle tissue. If you are an active athlete, you will have more muscle mass, and your training will damage your existing muscle. Therefore, these individuals are going to need more protein. On the other hand, the average American male needs about 110 grams of protein per day, and the average American female requires about 90 grams per day. That amount of protein should be spread out throughout the day. This means you should eat no more protein at a meal than can fit on the palm of your hand. That’s about 3 ounces of protein for a female and 4 ounces for a male. Q. What are the primary nutritional differences between animal protein versus plant protein? A. Of the 20 amino acids in any protein source, only nine are essential. This designation is because essential amino acids can’t be synthesized by the body and must be supplied by the diet. Animal protein has a complete range of amino acids, whereas plant protein is usually deficient in some essential amino acids. Q. Does protein build muscle mass? A. To help with muscle growth, you need adequate protein in the diet and weight-bearing exercise.Simply consuming more protein doesn’t build muscle. Exercise causes muscle damage and this stimulates new muscle formation to replace the muscle that has been damaged. The higher the intensity of exercise, the more protein you need. Q. Does protein increase satiety? A. A benefit of adequate protein consumption is that it increases satiety. It does this by releasing hormones from the gut that go directly to the brain to stop hunger and by increasing the release of the hormone glucagon from the pancreas to stabilize blood sugar levels. This lack of appetite is why you want to consume adequate protein at every meal, especially breakfast. Q. Can you consume too much protein? A. The answer is yes. Of the nine essential amino acids, three are branched-chain amino acids. These amino acids are leucine, isoleucine, and valine, and these have the most significant effect on stimulating muscle development by activating the gene transcription factor called mTOR. High levels of mTOR are associated with insulin resistance, eventually leading to many chronic diseases such as diabetes and cancer. Q. Is there a connection between mTOR and AMPK? A. The more you activate mTOR, the more you inhibit your master regulator of metabolism known as AMPK. Low levels of AMPK activity ultimately cause insulin resistance. As a result, you want to keep your protein consumption in a zone; not too high but not too low. With this as a background, let’s talk about using protein powder to ensure you get enough protein to maintain your muscle mass but not too much to inhibit AMPK. Q. What are the benefits of using protein powder? A. Many of our meals, especially breakfast, can fall short on protein. If you are over the age of 50, you are likely not getting enough protein in your day. Protein is vital as we age since older adults are prone to losing muscle mass, resulting in loss of strength and function. Protein powder can help fill in the gaps when intake falls short. Isolated protein powder can also help balance out excess carbohydrate intake to provide a better hormonal response at meals generating stable blood sugar levels and hence greater satiety between meals. Q. Can protein powder help with weight management? A. It can as it helps to create satiety and minimize cravings. Q. How should protein powder be used? A. It should be used as an additive to carbohydrate-rich meals. For example, adding protein powder to oatmeal provides a superior meal compared to oatmeal alone, or adding protein power to a fruit smoothie will give excellent appetite suppression. Q. Can you use protein powder daily and is there a better time of day to use it? A. Yes, you can use protein powder daily as long as you don't exceed your daily protein requirements. Breakfast is probably the best meal to use it since that meal is most likely to contain excess carbohydrates relative to protein. Q. Who should use protein powder? A. Anyone who does not feel they are getting enough protein in a meal. Q. How do you know if it’s right for you or working? A. Your best indicator is the increasing lack of hunger after a meal. Q. Are there any negatives to using protein powder? The key with protein powder is making sure you do not consume too much relative to the rest of your meal. I generally tell people to aim for a total of 25 grams of protein at each meal and about 7-14 grams at each snack. This takes into account all of the sources of protein at each meal and a good gauge to know how much to consume. You do want to pay attention to the quality of the amino acids in the protein powder you choose. Some sources such as collagen are very poor in essential amino acids and therefore would not be recommended. Q. What type of protein powder is best, and what ingredients should you look for? A. I think dairy protein powders are best, but recommend looking for ones that are lactose-free. Plant-based protein sources such a soy or pea don't have the taste of dairy-based protein powders, but can be used for those who avoid dairy. All protein powders are superior to collagen protein which is highly deficient in essential amino acids. Have more questions for Dr. Sears? Drop them in the comments below!
Dr. Sears Answers Your Weight Loss and Plant Based Questions
From Weight Loss to Plant Based, Dr. Sears is answering your questions. See some of the latest customer submitted questions and what Dr. Sears has to say in his latest blog. Q: What would you say are some of the most common dieting mistakes that make it harder to lose weight? A: The biggest mistake is not addressing the underlying cause of weight gain which is increased insulin resistance. Reducing insulin resistance requires a different dietary strategy than simply reducing calories. You have to activate the master regulator of metabolism which is AMPK. To do so cutting back on calories has to be supplemented with omega-3 fatty acids and polyphenols, both of which activate AMPK. The combination of the three dietary strategies is the best long-term way to reduce insulin resistance. Q: How do these habits make weight loss difficult or lead to weight gain? A: Getting adequate levels of omega-3 fatty acids will likely require supplementation. Getting adequate levels of polyphenols will require consuming far more non-starchy vegetables and fruits than most Americans currently do. Alternatively, one can use polyphenol extracts. Q: What tips can you offer for breaking these habits/creating healthier ones? A: Realize that reducing calories must be followed on a lifetime basis to be successful. Adding omega-3 fatty acids and polyphenols can increase dietary compliance by their activation of AMPK. This supplementation with omega-3 fatty acids and polyphenols will not only burn fat faster but also reduces insulin resistance which is the underlying cause of weight gain in the first place. Q: What are the best metabolism-boosting foods to put on your plate every day? How do these foods help boost your metabolic rate? How can this help aid weight loss? A: The cause of a slow metabolism is a condition known as insulin resistance. The molecular mechanism of insulin resistance is the inhibition of AMPK, which is the master regulator of metabolism in every cell. To speed up metabolism, you must activate AMPK. One class of nutrients that activates AMPK are polyphenols. These are found in low concentrations in fruits and vegetables. The more colorful the fruits (like berries) or vegetables (like artichokes) the more polyphenols. Unfortunately, you need to consume about 10 servings of such polyphenol-rich fruits or vegetables per day to get enough to activate AMPK. However, any AMPK-activating properties of polyphenols can be inhibited by consuming excess calories or glucose. So, to speed up your metabolism, you need to consume a calorie-restricted diet low in low in starches (bread, pasta, rice, and potatoes), and rich in fruits and vegetables. Q: More and more people are going plant-based for various reasons whether it’s health, animal welfare, trying to reduce the carbon footprint etc. A recent study showed that a diet rich in healthy plant-based foods may lower the risk of breast cancer but not if that diet is high in unhealthy foods, particularly juice and chips. What are your thoughts on plant-based diets and how they may impact cancer risk? A: A plant-based diet is lower in branched-chain amino acids. Branched chain amino acids can activate the gene transcription factor mTOR which promotes tumor growth, so moderating your intake of branch chain amino acids can help minimize cancer risk. As this study points out, it makes no sense to consume a plant-based diet rich in unhealthy foods. Foods rich in processed carbohydrates are high in glycemic carbohydrates which promote insulin secretion and can activate the IGF-1 pathway that also activates mTOR. Since cancer can be considered an inflammatory disease, you must follow an anti-inflammatory diet to have the maximum effect on reducing cancer development. Such a diet is calorie-restricted but rich in omega-3 fatty acids, and polyphenols all of which activate AMPK that inhibits mTOR in addition to optimizing immuno-metabolism to better eliminate cancer cells. Q: For vegetarians it’s a bit easier to find non-animal protein sources but for vegans trying to find adequate protein sources that are low-glycemic can be challenging. Which sources do you recommend? A: I think the better choices for vegans that are lower glycemic are tofu, tempeh, seitan and for those trying to minimize soy intake, supplementing with a pea protein powder. Also increasing intake of higher protein vegetables like asparagus, broccoli, Brussel sprouts, cauliflower, and mushrooms to name a few can aid fewer carbohydrates to your meal in addition to being great sources of fermentable fiber and polyphenols.

Scrumptious Asparagus
Asparagus is loaded with essential vitamins and minerals. Even more important in my opinion, it’s rich in fermentable fiber. Eating a variety of non-starchy vegetables and fruits, specifically those known to be high in fermentable fiber, adds to the diversity of bacteria in the gut which gives many health benefits. You can read more about this in “The Resolution Zone” by Dr. Barry Sears. What we know: Asparagus is actually the shoot of a perennial flowering plant. In years past it was typically harvested in the spring but it’s now available fresh all year round. I was surprised to learn recently that one asparagus plant can produce shoots for approximately 20 years. I’ve included some tips here and a couple of easy delicious ways to enjoy asparagus. Both of these dishes can be put together in 10 minutes or less. Think of them as starting points rather than recipes. The asparagus is the star of the show here. Feel free to make these dishes your own by changing up the flavors and spices you add. There’s no right or wrong way. Have fun with it! Tips for fresh asparagus Store as you would cut flowers by trimming off the end and standing it up in a glass or jar containing about an inch of water. Cover the top with plastic and it will keep in the refrigerator for up to four days. Wash with a quick rinse under cold running water and pat dry with a towel. Before using remove the tougher woody part at the lower end of the stalk. Scrumptious Raw Asparagus Salad This one’s got a lot of crunch, a little heat, and a fresh bright flavor. I make it all on a large cutting board for easy cleanup. To turn it into a meal, add some lean protein on the side and a bowl of strawberries for dessert. Method: Bunch the raw asparagus shoots together on a large cutting board and chop on a slant. I prefer thin shoots cut into small bite-sized pieces. Sprinkle desired amounts of freshly ground black pepper, sea salt, red pepper flakes, and finely grated Parmesan onto the asparagus. Add some roughly chopped walnuts, toasted if you like. Zest some lemon with a Microplane (yellow skin only, not white) and add it on top. Squeeze fresh lemon juice on top of it all and drizzle with olive oil. Give it a quick toss lightly on the board with one hand. Using a spatula transfer it to a serving plate. Balsamic Asparagus, Feta, and Cherry Tomatoes with Zone Orzo This dish came together several years ago from what happened to be in my fridge at the time, and it’s a keeper. Have cooked Zone PastaRx Orzo on hand in the fridge for a quick meal anytime. Method: Place raw asparagus shoots on a cookie sheet covered with foil. Foil makes clean-up easy. Season with S&P and drizzle with olive oil. Place it under the broiler and watch closely. Remove when it begins to brown (about 4-5 minutes for narrow shoots). Flip the shoots over and put them back under the broiler for another minute or two taking care not to burn them. While the asparagus is under the broiler, heat some cooked Zone PastaRx Orzo on a dinner plate in the microwave. Place the asparagus, some halved cherry tomatoes, and some crumbled fat-free feta on top of the orzo. Drizzle with balsamic vinegar and olive oil. Serve immediately. Enjoy!
Seasonal Spices and Their Health Benefits
When we think about spices this time of year, we think of those that create warmth and provide comfort. Anise, allspice, cardamom, cinnamon, cloves, ginger, and nutmeg are popular spices in the fall and winter. They are interwoven into the season for the warmth they create but can be used year-round. Spices have been used for centuries for their medicinal purposes, and as flavoring agents and to preserve food. While including spices in your meals is a great way to enhance flavor, it significantly increases their healthfulness since they are a rich source of polyphenols and antioxidants. Here we break down each of these spices, tell a little about their health benefits and give you a few ideas on foods they pair well with. Anise: Anise comes in different varieties; seed, fennel, and star. It is known for its licorice flavor that comes from a compound call anethole. Anethole is found naturally in high concentrations in the oils of anise and is used in a variety of medicines and pharmaceuticals (1). Anise pairs well with fish and stews. Star anise is one of the main ingredients in Chinese 5 spice powder and Chinese cuisine (2). Allspice: Allspice is derived from the dried berries of the Caribbean tropical tree, Pimenta dioica. It is used in Central American cuisines (i.e. think jerk dishes in Jamaican cuisine) for seasoning meat and desserts. It is rich in polyphenols known for their anti-bacterial, anti-hypotensive, anti-neuralgic, and analgesic properties and studies in animals show some of the compounds it contains may offer protection against tumor growth (3,4). Cardamom (Green): Cardamom is a part of the same family as ginger and is made from the seeds of different plants. Studies have shown it plays a role in oxidative stress by enhancing anti-inflammatory enzymes. Its benefits are diverse in that it’s been linked to improvements in blood sugar and lipid markers (5), gastrointestinal health as well as a potential role in chemoprevention (6). It has a sweet and pungent taste and pairs well with chicken and lamb and is used in Indian and Middle Eastern cuisine. Cinnamon: Cinnamon comes from the inner bark of several trees. While it's popular for its role in many foods as a flavoring agent and condiment, it is well known in the literature for lowering blood sugar levels (6). Cinnamon pairs well with many spices, apples, cocoa, breakfast and brunch options and can be found in Indian, Mexican, Moroccan and Middle Eastern cuisine. Cloves: Cloves have one of the highest polyphenol counts clocking in at 16047.50 mg/100 g. It has antibacterial, antiviral, and antifungal properties which are largely attributed to its high polyphenols and unique oils. When it comes to food they pair well with baked ham and pork and work well with many other spices too. Ginger: Ginger is a root derived from the Ginger plant, a member of the turmeric family. It is thought to have originated in India. It is used in foods for its hot, fragrant spice but also is popular in medicine (1). Studies have shown its role in combating nausea, minimizing inflammation, managing blood lipids, aiding in tumor suppression and growth, and as anti-bacterial agent, too. Nutmeg: Nutmeg and mace are relatives in that they come from different parts of the same tree. They are derived from an evergreen tree indigenous to the Spice Islands in Indonesia (1). Nutmeg leans a bit sweeter in taste and while there are many foods it can be used with it pairs well with cheese/cheese dishes, cream, milk and spinach. This is one of the primary spices you’ll find in Eggnog during the holiday season (2). A little goes a long way when it comes to flavor. Favorite Fall and Winter Spices Did you know that your favorite seasonal spices can easily be made at home as they are just combinations of the spices above? Gingerbread Spice: Ginger, Cinnamon, Nutmeg, Cloves, and Allspice Pumpkin Pie Spice: Cinnamon, Ginger, Nutmeg, and Cloves Apple Pie Spice: Cinnamon, Ginger, Nutmeg, and Cardamom Why Dr. Sears Like Using Spices The best raw fruits (primarily berries) contain about 0.1 % of weight as polyphenols, raw vegetables about 0.2%. Dried spices are about 5% of their weight as polyphenols. This why they are so bitter. The ultimate benefit of polyphenosl is to activate AMPK which in turn inhibits Nuclear Factor Kappa B (NF-kB). This reduces cytokine formation. Most polyphenols are totally water-insoluble and therefore can't be absorbed. However, they can be metabolized by bacteria in the colon to smaller fragments containing phenolic structures that can be absorbed. This is why we recommend consuming various sources of polyphenols during the day; fruits, vegetables, spices and also maqui berry. The beauty of maqui berry polyphenols is they are directly absorbed by the body to have maximal impact on activation of AMPK. Tips For Incorporating into Your Foods We tend to be creatures of habit with our meal prep, but spices have a way of elevating the taste of anything we make to have it feel new and different. To avoid over-powering your dishes start adding a sprinkle or pinch first and then add small amounts as needed. Here are a few ways to add them into your day. Add them into your roasted vegetable mixes and stir-fries Rub on top of your meats for cooking or use them in your marinades Mix into yogurt and oatmeal Add into sour cream, plain yogurt and hummus for dipping vegetables and fruit Sprinkle them on top of your coffee grounds or into your tea before brewing Add into your sauces, soups, and stews Incorporate into salads and salad dressings You May Also Like: Herbs and Spice - What to Know References Rosa Vázquez-Fresno, Albert Remus R.
