Dietary Health ClaimsFrom: AMD (anonymous@obgyn.net)Thu, 24 Aug 2000 18:24:09 -0500 (CDT)
I had a long discussion with my mother-in-law this morning about why protein is bad for you and a diet of fruits and vegetables is the way to go (her opinion -- not mine). She has gotten into this "juicing" thing, and has entire meals that are a mixture of various veggies or fruit that she has juiced together. She's trying to eliminate animal protein and dairy from her diet. During this conversation, she had a couple of remarks that puzzled me and I wondered if somebody could shed some light on the validity of these claims: 1) All non-vegetable protein is bad for you - you'll get all the protein you need from vegetables (and she's not talking about legumes). She claims that protein (animal, vegetable, or otherwise) raises the acidity in your body and your body takes calcium from your bones to balance out the acidity. I can see this if your protein consumption exceeds your kidney's ability to remove the waste products, but is this honestly an issue for the average healthy person eating a typical diet? Can normal protein consumption really upset the acid-base balance in your body to the point of calcium loss? 2) That one of the best things about juicing is that the nutrients go straight to your bloodstream and don't have to go through your digestive system and all the acid in your digestive tract-- a good glass of juice starts making you feel better almost immediately. Now my 10th grade biology class taught me that virtually all nutrients are absorbed from food (or juice, in this case) in the small intestine, and the path to the small intestine is through the stomach and its acid. The only way this makes sense is that the juice reaches the small intestine faster since it doesn't have to be broken down as much in the stomach. Is it possible for nutrients to go "straight into the bloodstream" without going through the stomach and small intestines? Thanks, Andrea
