Elsewhere the paper notes that vegetarians and vegans (including athletes) 'meet and exceed requirements' for protein. And, to render the whole we-should-worry-about-getting-enough-protein-and-therefore-eat-meat idea even more useless, other data suggests that excess animal protein intake is linked with osteoporosis, kidney disease, calcium stones in the urinary tract, and some cancers. Despite some persistent confusion, it is clear that vegetarians and vegans tend to have more optimal protein consumption than omnivores.

Vegetarians always ask about getting enough protein. But I don't know any nutrition expert (who) can plan a diet of natural foods resulting in a protein deficiency, so long as you're not deficient in calories. You need only 5 or 6 percent of total calories in protein... and it is pratically impossible to get below 9 percent in ordinary diets.
Advocacy of leaf protein as a human food is based on the undisputed fact that forage crops (such as lucerne) give a greater yield of protein than other types of crops. Even with conventional food crops there is more protein in the leafy parts than in the seeds or tubs that are usually harvested.
After a workout, you definitely have to have a protein shake. I drink my six-pound whey protein all the time, too. I throw some fruit in there - strawberries, blueberries - with some peanut butter and banana, and it gives you all the recovery you need from a hard day of lifting and running.
For 'The Rise of Cobra,' I was dieting more and using protein powder to help supplement my meals. For 'Retaliation,' however, I opted for more natural protein. I had a chicken breast and broccoli meal about five times every day. I also drank plenty of water and made sure I got enough rest.
Geography is the key, the crucial accident of birth. A piece of protein could be a snail, a sea lion, or a systems analyst, but it had to start somewhere. This is not science; it is merely metaphor. And the landscape in which the protein "starts" shapes its end as surely as bowls shape water.
The problem of different sensitivities of distinct protein groups to lysosomal inhibitors has remained unsolved and may have served as an important trigger in the future quest for a non-lysosomal proteolytic system that may be involved in at least certain aspects of intracellular protein degradation.
I think it's impossible to maintain a good, strong, muscular physique without taking some supplements. Between the protein shakes and the multivitamins that I take, I use C4, the pre-workout mix. I try to keep it as basic as I can, but I think I would shrink and disappear if I stopped taking protein shakes.
I have this wonderful personal chef who sources and stocks all my organic produce and I basically live on five smoothies a day. I'm totally vegan. I blend this green concoction with kale, cucumber, broccoli, string beans, avocado. My protein comes from protein powder. There is absolutely no milk, butter, cheese.
I don't avoid carbs. I don't avoid protein. I think it's just, again, about balance and finding what works for you and your body. For me, having a higher protein, higher carbohydrate, and middle-of-the-road fat count usually gets the job done as far as my energy needs and for my physique.
In order for life to have appeared spontaneously on Earth, there first had to be hundreds of millions of protein molecules of the Ninth Configuration. But, given the size of the planet Earth, do you know how long it would take for just one of these protein molecules to appear by chance? Roughly 10 to the 243rd power, billions of years; and I find that far, far more fantastic than simply believing in a god.

A cow out on grass is just an incredible thing to behold... Cows and other ruminants can do things we just can't do. They have the most highly evolved digestive organ on the planet, called the rumen. And the rumen can digest grass. It takes grass, cellulose in grass, and turns it into protein, very nutritious protein. We can't do that.
Thanks to this availability of suitable wild mammals and plants, early peoples of the Fertile Crescent could quickly assemble a potent and balanced biological package for intensive food production. That package comprised three cereals, as the main carbohydrate sources; four pulses, with 20-25 percent protein, and four domestic animals, as the main protein sources, supplemented by the generous protein content of wheat; and flax as a source of fiber and oil (termed linseed oil: flax seeds are about 40 percent oil). Eventually, thousands of years after the beginnings of animal domestication and food production, the animals also began to be used for milk, wool, plowing, and transport. Thus, the crops and animals of the Fertile Crescent's first farmers came to meet humanity's basic economic needs: carbohydrate, protein, fat, clothing, traction, and transport.
We continually make decisions in private which affect the commonweal, as the ecologists (to take but one example) have shown us. When I keep my house warmer than it needs to be, I consume fuel which might help someone else keep warm, or keep a job. When the food I eat is high on the protein chain I contribute to a maldistribution of protein around the world. When I teach my children to be primarily concerned with private gain, I diminish the ranks of public leadership in the rising generation.

We have always underestimated the cell...The entire cell can be viewed as a factory that contains an elaborate network of interlocking assembly lines, each of which is composed of a set of large protein machines...Why do we call [them] machines? Precisely because, like machines invented by humans to deal efficiently with the macroscopic world, these protein assemblies contain highly coordinated moving parts.
This is a message to all those out there who think that you need animal products to be fit and strong. Almost two years after becoming vegan I am stronger than ever before and I am still improving day by day. Don't listen to those self proclaimed nutrition gurus and the supplement industry trying to tell you that you need meat, eggs and dairy to get enough protein. There are plenty of plant-based protein sources and your body is going to thank you for stopping feeding it with dead-food. Go vegan and feel the power!
I remember being denied a protein bar that I went in to buy. I was so hungry, and it was before an audition, and I ran in and tried to buy this protein bar. And I checked my bank account, and it was negative 17 cents... And I remember getting on the phone with my mom and laughing that I have negative 17 cents.
I try to eat healthy for the most part. When I cut weight, I cut pretty much everything out. I don't have protein when I cut weight other than what I might get from something like chicken breast. So I don't eat any extra protein, just because I'm trying to get the weight off. That's the only real diet I have.
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.

He said science was going to discover the basic secret of life some day, ' the bartender put in. He scratched his head and frowned. 'Didn't I read in the paper the other day where they'd finally found out what it was?' 'I missed that, ' I murmured. ' I saw that, ' said Sandra. 'About two days ago.' 'That's right, ' said the bartender. 'What is the secret of life?' I asked. 'I forget, ' said Sandra. 'Protein, ' the bartender declared. 'They found out something about protein.' 'Yeah, ' said Sandra, 'that's it.
