Lol, those are great!
@derail topic:
Here's something to consider: we don't actually use the protein. Our bodies break it down into amino acids, and then build protein we can use. Sure, fruits and veggies are low in protein, but they're high in amino acids. Of the amino acids we can't produce ourselves, nearly 100% of our needs can be obtained through a healthy balance of fruits and veggies. The rest can be found in consuming just a few ounces of a high source, such as salmon, each week. Not measured in ounces a day, ounces a week. Meat is nearly entirely unnecessary.
Those same acids can be obtained from non-meat sources, but they're in very low concentrations, and would require you to rebalance the rest of your diet to compensate for eating so much of the one thing.
Oh, and the average human can only digest about 6oz of animal protein in a single sitting, which is why they teach you in culinary and nutritional schooling that the optimal portion is 3-5 oz. Go to an American steakhouse. The 'petite' steak is 6oz. Other options are 9, 12, and 16oz. Once you pass 6oz, your body starts laying down cholesterol in your cardiovascular system to protect it.
And now I'm going to get off my 'eat healthier' soapbox, because I could break down exactly what each commonly consumed food does to your body, and this re-derail post would be 3 times larger
