This article is very long, but it is easy to get the point. If you choose to not read the whole article, the video at the end tells us about a major problem with some nutrition studies. There is also may be the influence of a conflict of interest and industry funding. Unfortunately, I wish this was not a problem, but it is what it is. Nevertheless, the quest continues to find the “perfect” diet. Good health and longevity is based on a complex interaction of many factors, not just diet and that is why we study healthy cultures such as found in the book “The Blue Zones.” By doing so, we can begin to understand the complex environmental and cultural factors and how they interact to keep us healthier and possibly enjoy long lives.
