Hey Kim. I'm guessing the D in DH is not standing for Dear or Darling today, is it!? I agree with you, protein is different. I'm not sure if your protein is a soy protein or not, but here is some info that you can throw back in your DH's lovely face!!!
1) Next to water, protein is the most abundant material in our body. Our body contains virtually no protein reserves, so we need high quality protein EVERYDAY. 50% of solid parts of cells are PROTEIN.
2) U.S. RDA for protein (50-65 g) is low copared to other nations (it's only 70-80% of Japans RDA). Dr. Bruce Miller, DDS, CNS, estimates U.S. popultion consumes average of only 70-80% of U.S. RDA of protein. "The key to optimum health is adequate, high-quality, complete protein."
3) If you are taking a soy protein supplement:
Phyto-chemicals and phyto-estrogen, which are essetnail for maximum human health, are not found in animal protein. Although they are not nutrients like vitamins and minerals, scientists beleive these plant chemicals show much promise in the prevention of cancer.
4) Animal protein does not contain the essential amino acids in any one serving. The amino acid levels are too low and take too long to digest.
5) Producing an alkaline base in the body improves the immune system and reduces the ablility of viral and bacterial growth. An acid base which is produced when you eat meat and dairy products reduces the immune system, increases the level of viral and bacterial growth and will lead to many problems. Soy products are alkaline based, which is essential for long-term health
6) Most proteins take too long to digest to maintain the amino acid and protein level. The body then must attack the muscles. This is why we loose muscle mass during our lifetime as we get older.
OK, that's all I got for now. If you need more reinforcement, let me know!!!
