Can you please recommend some effective sources of protein?

Chicken: Protein sources are labeled as: complete proteins (provide all essential Amino Acids (aa) in sufficient quantity), e.g., chicken, fish, eggs, milk & cheese. Incomplete proteins (either do not provide all essential aa or provide all Amino Acids in not sufficient quantity), e.g. Rice, beans, tofu and soy. Plant proteins are incomplete. You must combine them to get all of the Amino Acids body needs.

Protein: Please see a licensed nutritionist for recommendations specific to you. In general, eggs are a good source of protein despite the misinformation about cholesterol. Meat from free range cattle and chickens is good also. There are protein powders that can be mixed w/water but make sure the product is from free range cattle to avoid hormones, antibiotics, etc. Peace and good health,.
