Although protein deficiency is widespread in poverty-stricken communities and in some nonindustrialized countries, most people in industrialized countries face the opposite problem—protein excess. The RDA for a 70-kilogram (154-pound) person is 56 grams; however, the average American man consumes approximately 100 grams of protein daily, and the average woman about 70 grams. Many meat-loving Americans eat far more protein. Some research suggests that high protein intake contributes to risk for heart disease, cancer, and osteoporosis. However, because high protein intake often goes hand-in-hand with high intakes of saturated fat and cholesterol, the independent effects of high protein intake are difficult to determine.

In describing a protein it is now common to distinguish the primary, secondary and tertiary structures. The primary structure is simply the order, or sequence, of the amino-acid residues along the polypeptide chains. This was first determined by [Frederick] Sanger using chemical techniques for the protein insulin, and has since been elucidated for a number of peptides and, in part, for one or two other small proteins. The secondary structure is the type of folding, coiling or puckering adopted by the polypeptide chain: the a-helix structure and the pleated sheet are examples. Secondary structure has been assigned in broad outline to a number of librous proteins such as silk, keratin and collagen; but we are ignorant of the nature of the secondary structure of any globular protein. True, there is suggestive evidence, though as yet no proof, that a-helices occur in globular proteins, to an extent which is difficult to gauge quantitatively in any particular case. The tertiary structure is the way in which the folded or coiled polypeptide chains are disposed to form the protein molecule as a three-dimensional object, in space. The chemical and physical properties of a protein cannot be fully interpreted until all three levels of structure are understood, for these properties depend on the spatial relationships between the amino-acids, and these in turn depend on the tertiary and secondary structures as much as on the primary. Only X-ray diffraction methods seem capable, even in principle, of unravelling the tertiary and secondary structures. [Co-author with G. Bodo, H. M. Dintzis, R. G. Parrish, H. Wyckoff, and D. C. Phillips]

High animal protein in take was positively associated with mortality and high plant protein intake was inversely associated with mortality, especially among individuals with at least 1 lifestyle risk factor. Substitution of plant protein for animal protein, especially that from processed red meat, was associated with lower mortality, suggesting the importance of protein source.

Hunger gives flavour to the food.

The paleo diet uses a distorted view of ancient history to argue that a diet of 50 to 80 percent animal products is the most life span enhancing. (This recommendation is double to triple the average animal product consumption in America today.) Early humans ate many different types of diets in various parts of the world, but what they ate here or there is not even the relevant question. It is how long they lived, and how long present humans will live (in good health) with various diet styles that is more relevant. The answer to this question is clear as the preponderance of evidence is overwhelming today.

Some people when they see cheese, chocolate or cake they don't think of calories.

Sources of Plant Protein Grains and grain products, legumes (lentils and dried beans and peas such as kidney beans or chickpeas), starchy vegetables, and nuts and seeds all provide protein (see Table B). A serving of a grain product or starchy vegetable provides an average of about 5 grams of protein, a serving of legumes provides 10 to 20 grams of protein, and a serving of vegetables provides about 3 grams of protein. Although a serving of these foods contains less protein than a serving of meat, you can eat more plant protein foods for fewer calories.

The nutritional composition of beef provides much-needed protein, vitamins and iron.... Let us also not gloss over what is beef's most obvious benefit: Livestock take inedible and untasty grains and convert them into a protein-packed food most humans love to eat.

The mind likes a strange idea as little as the body likes a strange protein and resists it with similar energy. It would not perhaps be too fanciful to say that a new idea is the most quickly acting antigen known to science. If we watch ourselves honestly we shall often find that we have begun to argue against a new idea even before it has been completely stated.

Whether through grains, beans, or even fruit, there’s plenty of protein in a plant-strong diet. We only need 5-8% of our calories from protein, and since protein is the one macronutrient that we can’t store, when you get above 15% it either stores as fat or we excrete it.

We can eat meat, it tastes good, but it’s very costly considering the land we have to use to produce the plants needed to feed the animals. And then we have a huge consumption of water for every kilogram of meat (produced), which is around ten times higher than for the plant.

And of course, identifying all human genes and proteins will have great medical significance.

Food is the essential thing to gaining weight. Protein, you know, that's basically it - protein.

Cacao has great nutritional value, a lot of protein, which strengthens a person, and without sugar it is not fattening.

Arteriosclerosis can be considered a disease of protein intoxication.

I usually have my protein at lunch and my carbs at night - I don't mix protein and carbs.

I always have applesauce in my fridge, and when traveling I take protein bars just in case I get hungry. They're my go-to snack.

I drink a lot of protein shakes and do a lot of weight lifting.

I eat 230 grams of protein daily, 308 grams of carbohydrates, maybe 70 grams of fat. I can have one cheat meal a week but it can't be that I eat until I'm stuffed; I eat until I'm satisfied.

I find that protein wakes up my brain and gets me ready for the rest of my day.

If one compares the sequence of amino acids that go to form the protein haemoglobin, it becomes apparent that humans and chimps are identical and do not differ in a single site.

In terms of personal choices, let's all think more carefully about where we get our protein from.

I only eat fish - no chicken, no turkey, just fish. I get all my protein from fish and egg whites.

I played around with vegetarianism back in the '70s. One thing, my physiology just got to have animal protein. I get hypoglycemic, I get all light-headed unless I eat animal protein.

Is it 10g of protein more or 10g of protein less, who cares, just get started

It now seems certain that the amino acid sequence of any protein is determined by the sequence of bases in some region of a particular nucleic acid molecule.

Skin is made in large measure of a protein called collagen.

Moreover the incorporation requires the same components needed for protein synthesis, and is inhibited by the same inhibitors. Thus the system is most unlikely to be a complete artefact and is very probably closely related to genuine protein synthesis.

There is absolutely no nutrient, no protein, no vitamin, no mineral that can't be obtained from plant-based foods.

Sugar leaves you stranded; I make sure I have the proper amount of protein before I work out.
