Document Summary

Vitamin supplements -> anti-oxidants actually increased cancer. Fruits ^ veggies (true, but not as good as exercise) Retrospective - looking back, weak study no protection.

Structure - are what you eat: water (cell tarsidity, lipid (cell membranes, protein (muscle, organs, connective tissue, minerals (bone & teeth) Kilocalories = calories = kcal: carb = 4 kcal/g, protein = 4 kcal/g, lipid = 9 kcal/g -> energy dense, alcohol = 7 kcal/g -> energy dense. Nutrients regulate our metabolism, fluid balance, acid/base balance. Involuntary activity: synthesis - protein catalysts -> enzymes, energy release. Anecdotal evidence - listening to other"s stories: you hear vitamin x cures headache. Or coincident, probably get better, same time as vitamin.
