Beta Glucan and the Microbiome: Debunking Myths & Understanding Their Role in Your Diet

My videos on prebiotics seem to be among my most popular. With that said welcome to this blog on beta glucan. I recommend beta glucan sparingly, because the dosing to microbial impact is inferior to a number of other prebiotics. However, it is very well suited to specific goals and should be a part of your daily diet. I see more and more videos online from so-called experts bashing oatmeal and other grains, and to some degree only recommending animal proteins and fats. This is misplaced faith and contrary to so many basic principles. For example, if we look at the longest-lived people on the planet, they are not radicalized carnivores. They eat a whole foods diet, which contains cereals, among other healthy things they do. As you watch my video, keep an open mind, view the data, use common sense, and don’t get caught up in dietary fads.  

Beta glucans can be found in a number of foods. Many of you may appreciate the fact that mushrooms for example, contain beta glucans. But in my video, I don’t discuss mushrooms, nor other sources such as other cereals. I focus on barley and more specifically oat beta glucans. Why is that? Because the data I present is related to the well proven benefits of beta glucans on serum lipids and sugars. These benefits are not at all proven for mushroom beta glucans, and are so well proven for oat and barely beta glucans, that the United States Food and Drug Administration has approved the use of a health claim for the impact of cereal β-glucan in reducing the risk of coronary disease and the European Food Safety Authority has approved health claims for cereal β-glucans related to a reduction in postprandial glycemic responses and total and LDL serum cholesterol. I also focus of the benefits of fermentation. 

As in all of my videos, I provide the scientific evidence to support what I’m saying. Is anyone else doing this? I realize my content can be a bit dense, but for a certain percentage of people, and it’s small, it’s right up their alley. I find that in general, when I conduct my consultations with individuals who have found me via my videos, they are very well versed in their respective condition, as well as nutrition and other aspects of health. In fact, I’d place bets that some of them know more about their condition than do their practitioners. With that said, they look to learn something new. If the content were any less, I’d be like everyone else online, and you would wonder how I can call myself The Microbiome Expert. So, if my videos are not for you, I understand. But if you are one of those people taking a vested interest in their health, and are looking for a more intelligent way forward, then “welcome”. 

As the former director of medical education for a microbiome firm, and now with my own platform, I have helped many people over the years. And now, I bring this knowledge directly to you. In our world as it is, we all now have to be our own health advocates. With a broken government, food and medical system, you need to take charge of your healthcare. So, educate yourself, as best you can. This is why I’ve launched my educational platform. You can find my presentations entitled, “The Prebiotic Beta Glucan, the Microbiome and Your Health” in my Microbiome University tab, and also on my YouTube channel. If you have a condition or disease that you think would be well served by addressing your microbiome, you can visit the Protocols tab on my website where you can find a science-based protocol which may dramatically improve your quality of life, as they have done for many others (see my testimonials)
