Dr. Barry Sears Answers Your Questions on Omega-3 Fish Oil

 Dr. Sears answers some of the top questions we receive about fish oil and omega-3 fatty acids and what makes OmegaRx 2 unique.  

What are EPA and DHA?
EPA is an abbreviation for the omega-3 fatty acid Eicosapentaenoic Acid. DHA is short for Docosahexaenoic Acid. The anti-inflammatory properties of fish and fish oil are mainly due to these two omega-3 fatty acids. The benefit of EPA and DHA comes from reducing cellular inflammation by inhibiting the formation of inflammatory hormones (e.g. eicosanoids) derived from the omega-6 fat, Arachidonic Acid (AA).  However, their greatest benefits come from the generation of pro-resolution hormones (i.e. resolvins) that turn off the inflammatory process.  

If someone considers themselves healthy, why would they need to take omega-3 fatty acids?
Omega-3 fatty acids are considered essential fatty acids meaning they must be supplied in our diets. They are the building blocks for hormones that resolve existing inflammation. Unresolved inflammation is the primary reason we gain weight, develop chronic disease, and age at a faster rate. The typical American diet is very low in omega-3 fatty acids and rich in omega-6 fatty acids (the building blocks for pro-inflammatory hormones). This is why you need a high concentration of purified omega-3 fatty acids to make a difference in addition to lowering the levels of omega-6 fatty acids in the diet.

Why is fish oil superior to krill oil, flaxseed or other omega-3 products on the market?
Fish oil is made by heating fish to release the stored fats. From this crude fish oil, the omega-3 fatty acids can be further refined/purified into omega-3 concentrates. Krill oil is actually made of small shrimp that have been harvested and extracted using harsh chemicals (hexane and acetone). Furthermore, the omega-3 fatty acid content in krill oil is much lower than in omega-3 concentrates derived from fish oil. Flax seed oil is rich in alpha-linolenic acid (ALA). Although ALA is an omega-3 fatty acid, it has no health benefits unless converted into EPA and DHA. This conversion is very inefficient (about 1-10%) so you would have to consume large quantities to get the same benefits of a much smaller amount of omega-fatty acid concentrates.  

What is it about OmegaRx2 that makes it different from other brands?
The answer is purity and potency. OmegaRx 2 is highly purified to remove as many PCBs as possible and our standards are eighteen times more rigid than the industry standards. In addition, Zone Labs publishes the purity data for every lot of OmegaRx 2 on our website to give our customers total transparency. All omega-3 fatty acids are prone to oxidation which is why we publish the levels of stability (defined by the TOTOX level or rancidity in layman terms) on every lot of OmegaRx2 as well.  Our post production levels of rancidity are among the lowest on the market. Finally, the concentration of OmegaRx 2 is among the highest concentration of any non-prescription omega-3 fatty acid product on the market. 

How much fish oil do you recommend people take?
I recommend taking a daily minimum of 3 grams of EPA and DHA. That said, we use our Cellular Inflammation test to determine the ideal amount an individual requires. This test looks at the ratio of two key fatty acids in the blood: Arachidonic Acid (AA), an omega-6 fatty acid which is the building block for pro-inflammatory hormones, and EPA which is the building block for pro-resolution hormones. The AA/EPA ratio or Cellular inflammation Score will tell you with the most precision how much you need to take on a daily basis to optimize your overall wellness. It has been demonstrated that decreasing the AA/EPA ratio is strongly associated with a longer life. 

If my cellular inflammation score is ideal, do I need the heightened concentration? 
If your Cellular Inflammation Score is between 1.5 to 3 you are in the ideal range to promote future wellness.  The higher the Cellular Inflammation Score, the more inflamed you are.  The average American has a Cellular Inflammation Score of 20.  Resolution of inflammation is key to maintaining wellness, and this can only be achieved with a lower score.  It is possible to achieve an ideal AA/ EPA ratio or Cellular Inflammation Score within 30 days with the correct dosage of OmegaRx 2.

When will people start seeing the benefits after they begin to supplement and what will they be?
I generally tell people that it takes about 30 days to truly see the impact of supplementation in the blood, but it's only a matter of days that their benefits subside once you stop taking them. This means you have to be consistent with your intake of purified fish oils and take it daily. Omega-3 fatty acids have been shown to help support a healthy heart, brain function, behavior and mood regulation, cellular rejuvenation, athletic performance and recovery, and improved vision. Their benefits are due to their role in resolving excess cellular inflammation.

Do you have tips for how to take it? 
Most people do just fine taking our recommended dose of 4 capsules or 1 teaspoon of OmegaRx 2 daily. I always suggest taking it with food and if you want to split up your dose between morning and night to see how you do that is fine too. 

How long do you have to take it?
For a lifetime if you want to maintain wellness. Once you stop taking omega-3 fatty acids your levels of omega-3s will soon return to baseline within a few days.

What are the benefits of omega-3 fatty acids across the lifespan?

Fish oil or omega-3 fatty acids are critical across the lifespan. This is why they are essential nutrients.  It starts in the womb as they support brain development in utero in addition to minimizing post-partum depression for the mother. We now know that the dietary and metabolic environment the fetus is exposed to in the womb can echo through the rest of his or her so it’s critical to have good nutrition and adequate levels of omega-3s throughout pregnancy and after. The rise in conditions such as autism, ADHD, diabetes and heart disease in early childhood and young adulthood may have a connection with the high levels of omega-6 fatty acids in our diet and low amounts of omega-3s. I strongly believe that chronic conditions associated with aging such as heart disease, diabetes, cancer, and dementia start with the failure to resolve inflammation so by getting adequate levels of omega-3s early on you can help to promote a lifetime of wellness.  {{cta('70a4b644-a93c-4f8b-83ec-5be1500ed236')}}

Ketogenic Diets and Aging

Chances are, you or someone you know has tried the keto diet at some point in time. This high-fat, very low-carbohydrate eating plan appeals to many due to its promise of rapid weight loss. In this blog, Dr. Sears explores some of the latest scientific findings on ketogenic diets and provides caution before hopping on this trend. What is a Ketogenic Diet? The ketogenic diet is a high-fat, very low-carbohydrate eating plan. This significant reduction in carbohydrates to induce a metabolic state is called ketosis. This only occurs when there is not enough carbohydrates in your liver to completely convert fatty acids to carbon dioxide and water. The normal conversion generates the chemical energy (ATP) that keeps us alive. In the absence of ketosis, each fatty acid generates 108 molecules of ATP when oxidized in the mitochondria. Ketone bodies make less ATP when they are metabolized by mitochondria. How much less? About five times less. This is like switching the gasoline in your car from high-octane fuel to low octane fuel as ketone bodies increase in the blood. Furthermore, contrary to popular belief, ketones are not an ideal energy source for the brain, as glucose remains the preferred fuel for ATP production in brain cells. Lack of blood glucose is a highly stressful situation for the brain. This is why the body secretes the stress hormone cortisol from the adrenal glands during ketosis to breakdown protein and convert the amino acids into glucose for the brain. This explains why even under complete starvation for 38 days, the blood glucose levels never dropped below 68 mg/dL. This is still considered as a normal blood sugar level. Where did this blood glucose come from if there was none in the diet for 38 days? The answer is neo-glucogenesis primarily using lean body mass. Ketogenic Diets Pros and Cons Interest in ketogenic diets rises and falls about every 20 years. They’re very low-carbohydrate diets that claim that carbohydrates make you fat and keep you fat. This is simply not true. It is not carbohydrates per se but a disrupted metabolism that makes you fat. To be more specific, it is the inhibition of AMPK, the master regulator of your metabolism that makes you fat. Why? As AMPK activity increases, you burn stored fat faster. Frankly, I’ve always been amazed by the re-emergence of ketogenic diets. Eighteen years ago, I published the premier clinical study demonstrating that, under equal calorie intake in which all the food was provided to the subjects for six weeks, the Zone Diet was better than a ketogenic diet in reducing total weight, excess body fat, and inflammation. Now, a recent study revealed some more very concerning findings about the long-term effects of ketogenic diets. This new study indicated that following a keto diet causes a rise in senescent cells, popularly known as “zombie cells.” Zombie Cells are damaged cells that no longer divide but don't die. That’s bad enough, but zombie cells continue spreading inflammation throughout the body. As the number of zombie cells increases in your body, they become a living nightmare. Why? Zombie cells accelerate aging because they cause the earlier development of many chronic diseases. In this study they found that zombie cells in the animals began to appear while they were on a ketogenic diet. The zombie cells then disappeared when researchers changed the diet to a “non-ketogenic diet” (i.e., the Zone diet). And when the animals were given a Keto diet again, the zombie cells reappeared. Notice a trend? If you want to hear more about this study you can listen to our recent podcast at Dr.Sears.com. Based on earlier blogs, this adds to the list of downsides for following a ketogenic diet versus the Zone Diet. PROS Rapid initial weight loss: This is primarily due to the loss of retained water from the glycogen stores in the liver, which is rapidly used up to maintain blood sugar levels. Since these glycogen stores in the liver contain significant levels of retained water, much of the initial weight loss is water rather than stored body fat. If your main goal is loss retained water, this can be seen as a benefit. Of course, going to a sauna would also work. Reduced hunger: Ketogenic diets are rich in protein. Any increase in protein intake can help reduce hunger. CONS Production of acetone: One of the ketone bodies produced during ketosis is acetone, which is also the main chemical in nail polish. Increased calcium loss: A ketogenic diet can lead to higher calcium loss from bones. Limited fat utilization: High levels of dietary fat reduce the likelihood of using stored body fat for energy unless you also significantly restrict calories. Reduced energy levels: The lack of ATP production on a ketogenic diet can lead to easier fatigue during mild exercise. Damage from cheat meals: After seven days on a keto diet, a single high-carb cheat meal can damage blood vessels. Lack of polyphenols: This makes it difficult to activate genes that optimize metabolism by improving mitochondrial efficiency in converting fat into ATP. No long-term weight loss advantage: Long-term studies show no difference in weight loss between a ketogenic diet and a low-fat, high-carb diet. No short-term metabolic advantage: Careful studies demonstrate that fat loss on a ketogenic diet is the same as on a low-fat, high-carb diet with the same caloric intake. Compromised gut health: A lack of fermentable fiber from carbohydrates can lead to poor gut health and an increased risk of developing a leaky gut, which can cause significant inflammation. Furthermore, short-chain fatty acids (SCFA) are the metabolic product of fermentable fiber. These SCFA are powerful epigenetic signaling agents that enhance gene transcription. Ketosis generates a different type of hydroxylated short fatty acid (3-hydroxyl butyrate, that has no effect on gene transcription. In addition, the lack of SCFA has significant negative consequences on the gut-brain axis. Cortisol build-up: To produce glucose for the brain, cortisol levels increase to breakdown protein to make sufficient glucose via neoglucogenesis. Excess cortisol can lead to insulin resistance that cause regain of some of initially loss body fat. In addition, increased cortisol levels cause a depressed immune system as well as destruction of memory cells in the hippocampus. The initial benefits of following the ketogenic diet result in some initial weight loss (primarily water weight rather than fat loss), long-term studies show no significant differences in overall weight loss. Now new findings show a ketogenic diet may lead to significant adverse health consequences by accelerating the formation of zombie cells. Call me crazy, but I feel the key to longevity and wellness comes down to better metabolic control instead of living in a constant state of ketosis. Following Metabolic Engineering® for a lifetime provides that pathway of losing body fat without ketosis. References 1.

Tofu: Tips and Recipes Ideas

I have been eating tofu for a very long time, much longer than the 30 or so years I have been following the Zone Diet. Back then many of my favorite recipes came from the Tassajara cookbooks by Edward Espe Brown, the celebrated chef from the kitchen at California’s famous Zen Mountain Center, and cookbooks by Louise Hagler, a.k.a. Wendy Louise, a well-known authority on vegetarian cooking who is associated with a community in Tennessee known as The Farm. Those books are still among the best resources for tofu recipes. My mantra has always been if you don’t like something, don’t eat it. Keep this in mind if you’re new to tofu, start slowly by combining it with flavors and foods you like.    Tips and Suggestions    Firm-sprouted tofu is my preference for the Zone Diet. Unlike traditional tofu, which contains significant amounts of both protein and carbohydrate, sprouted has almost no carbohydrates. It’s lighter tasting, refreshing, and very filling.   Freezing tofu results in a chewy, sponge-like texture. I don’t recommend freezing, but some people prefer it when using tofu to substitute for meat in a recipe.    Baked tofu comes in a variety of flavors and makes an excellent quick meal with some vegetables and fruit added. It’s also great in salads.     Tofu made it into the book “The Top 100 Zone Foods” by Barry Sears.    Some recipes call for draining the tofu first. I find that usually isn’t necessary.   Tofu takes on the flavor of whatever is added to it.    Add nutritional yeast flakes to give a cheesy flavor to vegan tofu scrambles and dips. It’s also rich in protein and vitamin B12.   Cherry Vanilla Tofu “Ice Cream”   Tip: This doesn’t freeze or store well, so prepare only the amount you plan to serve immediately.   Using an immersion blender or a food processor blend equal parts of frozen dark cherries and firm tofu, plus some vanilla extract (preferably alcohol-free for best flavor). Serve immediately.  Tofu Scramble  This is great for breakfast, lunch, or dinner, and we’ve even brought it on long day hikes for a snack.   Crumble some firm tofu and stir in a generous amount of seasonings, taking care not to overdo it with the salt. Heat in a well-seasoned or nonstick skillet with a little Zone-friendly oil to the desired doneness.    Optional: If time allows, sauté some chopped onion in the skillet before adding the tofu and seasonings.    My favorite seasoning combination for this dish at my house is onion powder, garlic powder, turmeric, paprika, some oregano or thyme, nutritional yeast flakes, salt, and ground black pepper. The yellow color of the turmeric makes it somewhat like scrambled eggs.   Tofu Veggie Almond Pasta Salad   Dressing: Thin some smooth almond butter by stirring in some water, a little vinegar, and either soy sauce or Bragg’s Liquid Aminos (an unfermented soy sauce found in the health food section of most grocery stores).    Toss together cooked Dr. Sears’ Zone PastaRx Fusilli, tofu cut into cubes, matchstick cut red bell pepper, chopped green parts of scallions (a.k.a. green onions), and the almond butter dressing. Serve immediately or chill to serve later. It will keep well in the fridge for two or three days.   Use your imagination and see what you can come up with.  Experiment and have fun with it. Try using tofu to make cheesecakes, whipped desserts, tofu chocolate pudding, tofu “cream” based soups, tofu pot pie (think chicken pot pie), tofu burgers, tofu burritos, Buffalo tofu (like Buffalo wings), layered Mediterranean dips, tofu “meatballs”, grilled tofu, and more.    Enjoy!
