Protein is important. All of the body's enzyme systems are made from protein- and without them we could not sustain physical life.
Proteins are composed of building blocks called amino acids. Some of these amino acids cannot be synthesized in the body according to known biochemical pathways. And even if they did, it would require other enzymes (also made of protein) to synthesize them.
Thus, we must get protein from our diet. But from where and how much?
As with many health topics, there is a bunch of nonsense and propaganda floating around on the Internet by people who, in my opinion, should be more concerned about spreading truth than amassing followers. But they do have a right to free speech. Keep in mind that the nonsense and propaganda is espoused by both sides of the debate. Often times I wonder- why do so many people insist on reducing every subject down to "two sides" and then "duking it out" over who is right? Could it be some sort of mind control? But we'll save that discussion for another thread.
Of course, the truth is found somewhere in the middle.
Here is a great resource that I found that I found on a website called "No Meat Athlete". For what it is worth to those who value my professional opinion, I have checked the article for factual accuracy, and did not locate a shred of nonsense, propaganda, or misinformation.
Protein for Vegetarians — A Simple Guide to Getting What You Need
As you will see in the comments, it is highly acclaimed. I concur.
Of course, there are those few comments from people who claim that punching a couple of numbers into a calculator to figure out how much protein one needs is "too complex" or that keeping track of one's vegetable protein intake until it becomes second nature takes "too much time".
Just in case you, the reader, happen to fall into this category, here is a summary in as brief of terms as I can put it.
1. It is completely unnecessary to consume animal products in order to meet your protein needs. However, it may take a little more "work" especially in the beginning.
2. The average person needs about 60 grams of protein a day. By "average" I mean somebody who weighs around 165 pounds and is lightly active.
3. Protein needs vary according to one's metabolic rate. This means the more you weigh, and the more active you are, the more protein you need. There are many free tools on the Internet that will calculate this for you.
4. Fruits have little to no protein. Period. What little protein there is is mostly found in the seeds. This is because fruit is a storage facility for sugar, and is not very metabolically active.
4a. Some folks claim that fruits contain all the enzymes needed for the human body to digest them within. I find this to be a dubious claim as all enzymes are protein and fruits do not have much protein. According to the generally accepted knowledge of human biochemistry, the majority of digestive enzymes needed by the body are produced in the body by digestive organs such as the stomach, liver, and pancreas.
5. Most vegetables are poor sources of protein. However, since I am sure you are eating lots of them it does all add up to something significant. For example, if you are eating ten cups of vegetables a day that can contribute anywhere from 1/2 to 1/3 of your total protein needs. If you are regularly consuming around 20 - 30 cups of vegetables a day, you may in fact get all of your protein from these.
6. Nuts, seeds, and legumes (beans) are excellent sources of protein. They are all about 1/4 protein by dry weight, which is the same as meat. Therefore it is actually fairly straightfoward to figure out how much of these to eat. The answer is between 6 and 8 ounces of these a day. Keep in mind that if you soak or sprout nuts, seeds, and legumes the water adds weight, but not protein. Make sure you are calculating based on the dry weight.
6a. Some folks claim that soaking increases the protein content, however according to my understanding of biochemistry, this is a dubious claim as most protein synthesis occurs in the roots, which are associated with symbiotic microbes in the soil.
I hope you've enjoyed this post on vegetable protein. Have a wonderful day!
