Lots of great comments!
The "incomplete protein" is amazing marketing by the cattle industry. Why would anyone kill and eat an animal if there was no solid reason. I too believed this advertising until last year!

Now there are adults who never ate meat, raised by vegan parents. Where are all the "protein deficient"? As long as you eat enough calories you get all the essential proteins from plants. Plants are where cows get their protein. Even vegan body builders that set world records get plenty of protein without meat.

As for drinking lots water to correct excessive protein, that is a silly patch

Here is how i solved the kidney overload problem. The problem is not the smell, the problem is the food. Your body is telling you by the smell, that you need to eat better.
My breakfast and lunch are fine, just my bean dish had too much protein. First i cut out the kidney beans and added a little rice. Kept the lintels and black beans. Still too much protein

So, yesterday since i was a little hungry at 3:45pm, i split the dish in half, and added a small bowl of pasta to cut the protein. Then at 5:15 i ate the other half with a banana. This is all it took, and now if i keep doing the solution, my kidneys are much less likely to fail later in life.

Dauntless,
Vegetables and fruits, oatmeal, bread, pasta, are usually fine. There are 100's of foods that have normal protein. it is mostly meats, dairy, and eggs that have too much fat and protein, and cause serious health problems, like heart disease, cancer, diabetes, obesity, and 100's of other diseases. If you are lost in the woods starving, go ahead and catch an animal, and eat it, it can save your life.
But eat animals often and many end up with an early, painful, death.
