Document Summary
Nutritional facts table (food label: physiological impact. Gylcaemic index: degree to which they have been processed. Chloroyphyll in plant leaves uses enrages from sunlight to combine: Sometimes unre ned starchy foods or sugars in their natural state such as whole fruit (**this terminology not recommended: carbs in the diet are classi ed as: (1) sugars. Greater than or equal to sugar units: starch & dietary bre. Muscle (~200-300g) for muscle"s own use: stored w/ water, not found in foods. ; semi-crystalline structures, resistant to digestion: cooking in moist heat => gelatinization. Gelatinized starch is rapidly digested: cooling cooked starch => retrogradation. Polysaccharides & lignin not digested by human enzymes found intact in plant foods. Isolated indigestible carbs. shown to have bene cial physiological effects in humans. Sum of dietary bre & functional bre: soluble bre: Dissolves in water or absorbs water to form solutions. Usually is readily broken down (fermented) by colonic micro-organisms.
