Nutrition is about getting the nutrients to grow, survive, and reproduce, as well as to regenerate and maintain body functions. There are macronutrients and micronutrients. While macronutrients are carbohydrates, fats, and proteins, micronutrients are minerals and vitamins.
Carbohydrates: Honey, fruits and plain sucrose. Starch is also a sugar, but it excessively stimulates insulin. Fructose in sucrose or sugar can be metabolised for energy even when glucose can't, as in diabetes. In Ray Peat's words: "Fructose inhibits the stimulation of insulin by glucose, so this means that eating ordinary sugar, sucrose (a disaccharide, consisting of glucose and fructose), in place of starch, will reduce the tendency to store fat. Eating “complex carbohydrates,” rather than sugars, is a reasonable way to promote obesity. Eating starch, by increasing insulin and lowering the blood sugar, stimulates the appetite, causing a person to eat more, so the effect on fat production becomes much larger than when equal amounts of sugar and starch are eaten. The obesity itself then becomes an additional physiological factor; the fat cells create something analogous to an inflammatory state. There isn't anything wrong with a high carbohydrate diet, and even a high starch diet isn't necessarily incompatible with good health, but when better foods are available they should be used instead of starches. For example, fruits have many advantages over grains, besides the difference between sugar and starch. Bread and pasta consumption are strongly associated with the occurrence of diabetes, fruit consumption has a strong inverse association."
Fats: There are saturated, monounsaturated, and polyunsaturated fats. Polyunsaturated fats cause cancers, diabetes, obesity, stress, oxidative damage, supresses thyroid, increases inflammation. On ther other hand, saturated fats have the exact opposite effects of polyunsaturated fats, decreasing stress, preventing obesity, improving and accelerating thyroid hormone production, thyroid hormone transport into cell, tissues's responsiveness to thyroid, terminate the stress reactions, etc. Eat butter, coconut oil, and lamb fat, and avoid commercial vegetable oils, such as safflower and soy oil, margarine, and pork fat.
Proteins: Eggs, organ meats, milk and cheese, gelatin, and potatoes.
Minerals: Calcium, sodium chloride (salt), magnesium, potassium, copper, etc.
Vitamins: Vitamin A, Vitamin B3, Vitamin B6, Vitamin K, and Vitamin D, etc.
