Through recent revelations in science, we're now looking at a clearer picture than ever before. It's obvious really. Most people learn about genetic adaptation and natural selection in middle school, but for reasons we'll get into later, few health authorities seem to take any of that most basic science and apply it to health. Our bodies would run much smoother and feel better if we fell more in line with the ancestral habits that drove our evolution. Only in the last hundred years have we had the ability to lead sedentary lives while consuming large amounts of sugar and processed carbohydrates that are almost entirely devoid of bio-available nutrients. At the same time, hours spent indoors under artificial light have limited our exposure to the sun and consequently vitamin D levels which are essential for a whole host of biological functions, including testosterone production. We rely on the heat of oil furnaces as opposed to huddling around a campfire. This constant temperature control weakens our arterial and immune systems. Don't get me wrong, I'm a fan of modern conveniences; though I think it's important to consider how the things we do now are going to drive our further evolution, and if we're smart about it we can use our findings to enhance our own experiences on this planet.
Despite the work of some of the most prominent food manufacturers, who time and again have been proven to have paid off scientists to shift the evidence in favor of glorifying grains and sugar and demonize fat, the true science is coming to light. Our bodies evolved on varied diets depending on the location and surrounding environment, but certain common things set those apart from the standard American diet. In general, there is not commonly a large source of sugar, or carbohydrate in natural form that doesn't require large amounts of processing energy to be expended before consumption. Our bodies evolved to run on much less sugar than most people currently consume. The primary sources of energy actually available in nature are proteins and fats. Vegetables provide necessary fiber, vitamins and micro-nutrients, but offer little in the way of calories. When large amounts of sugar or carbohydrate are consumed, that causes a subsequent insulin spike in order to mitigate the amount of free sugar and store it as glucose. If the individual in question has used prior glycogen stores during exercise, some of that will be stored in the muscles. However, in sedentary individuals whose muscles haven't expended their glycogen stores, it is stored as fat. Not just in the stomach, but all over the body. Including on organs and inside arteries. The top cause of mortality in America today is Heart disease and I'm sure you're starting to see why.
In short, at Biofit we strive to educate those who are interested in trying to work along side of evolution, instead of against it. That's not a fight anyone can win for long.
