The food we eat is composed of macronutrients: protein, fats, and carbohydrates; and micronutrients: vitamins, minerals, and trace elements.
Proteins and fats are basic, bare bones essential nutrients for our health. We need 70-100 grams of protein a day (about 300 calories), and 6-10 grams of linoleic acids (about 75 calories). (Linoleic acid is a fat found in vegetable oils.) From those two food classes, our bodies can make everything we need for healthy living.
What about carbohydrates? We know that our cells, including the brain cells, run on glucose. So how much carbohydrate do we need to supply that glucose? The answer is none. Our bodies can break down the protein and linoleic acid molecules and reform them into whatever is needed, including glucose.
If you need proof, look at the traditional diet of the Eskimos. Their diets consisted of protein and fat during the summer months, and almost exclusively fat in the winter. They were strong, healthy, and lean.
It is nearly impossible to get the macronutrients, (protein, fat, and carbohydrate), in pure form. And, even if you could, 375 calories per day is not enough to satisfy our energy needs.
Proteins from animal sources are combined with varying amounts of fats, as in steaks, poultry, fish and eggs. Some carbohydrates (in the form of lactose)as well as fat are present in dairy products such as milk, yogurt and cheese. Fat-free dairy products are protein and carbohydrates.
Plant products have protein, but even the ones we think of as good protein sources, such as beans and grains, have more carbs than protein. Plants have some fats, mostly the “good” kind.
For maximum health benefits, add up grams of protein each day. Eat at least 70 grams. One tablespoon of olive oil is enough to take care of the linoleic acid.
OK, what to do with those carbs? Eat them sparingly. And only eat the high quality ones such as vegetables and fruits. If you have a weight control or diabetic problem, leave off the grains.
Carbs and fat combined are a slippery slope into insulin resistance and ill health. Refined flour products are no better. Pasta is a wolf in disguise.Not good for the body!
