Nutrition research can now tell us why green foods are important in our diet, and can also identify the specific health benefits which they provide. Dehydrated cereal grass is an excellent and convenient source of these nutritional benefits. The kinds of foods we eat are not the only source of health hazards associated with our diet. Diseases caused by food toxins have been identified throughout history. Some substances which occur naturally in foods can cause us problems.
Alkaloids are present in commonly consumed foods and herbs, as are a variety of enzyme inhibitors.
Substances such as oxalates and phytates inhibit the absorption of required nutrients. These substances are generally not consumed in quantities sufficient to cause noticeable health problems. Only in the present century have we been exposed to toxins which are intentionally added to crops and processed foods. Food additives have been around for several decades now, and evaluations of the safety or hazards of their long term use can now be made. Estimates of the hazards of newer food additives rely largely on animal experiments.
