The American diet, we are told by many top nutritional researchers that with its high concentration on processed foods, many artificial sweeteners and especially low-fat foods for dieters have all but depleted the daily intake of the essential fatty acids(Omega-3s) needed by the body to ward off many diseases. Research is also showing that deficiency of Omega-3 and Omega-6 over a long period of time may cause the onset of Alzheimer's disease. Some nutritional researchers are also finding links between low intake of essential fatty acids and the onset of Macular Degeneration, a disease of the eye. It is also a well known fact pointed out by many top nutrition researchers that without the intake of fat, not only the lack of Omega-3 essential fats, the vitamins, A, D, E and K will not be absorbed in the human body. We are told by these same researchers that even if a person eats fruits and vegetables to get their needed daily vitamins, they will not be absorbed unless fat is ingested along side and the fats that are primarily needed for all body functions are the Omega-3 and Omega-6 fatty acids.
