Many people in our modern world don’t realize they were never meant to eat wheat in their diet. And in fact a large percentage of the population has a major intolerance to the gluten in wheat grains.
People who are celiacs are the most sensitive to these types of foods. And its because the human digestive system has not adapted to eating large quantities of wheat in their daily diets.
In fact, it has only been introduced to us humans in large quantities as little as 80 or so years ago. A very little time frame when you compare it to what has been in our diets since the beginning of time when are ancestors where hunting meats and gathering vegetables, fruits, nuts and seeds.
