Make a list of the daily intake of foodstuffs.  Pay particularly close attention to digestion and in your food diary, make a note of health concerns after intake of anything that causes sensitivities, headaches, or various other discomforts and bodily concerns.  The notes can be used for future reference in deciding what may need to be temporarily or permanently discontinued.  Knowing what was consumed on a particular day and of the outside stressors involved that could play a role in the development of dietary changes is helpful. Many experts are beginning to agree that cholesterol should not be considered as the only concern when treating heart disease.
