ATKINS DIET CONTINUED
In the '60's it was the Atkins diet, in the 70's it became the Stillman Diet
and in the'80's it became the Scarsdale Diet. Protein Power Plan in the '90's.

PROTEINS IN NUTRACEUTICALS
Soy-lowers total and LDL cholesterolno effect on triglycerides and HDL cholesterol in adults
but get triglycerides down in some children-all of this is controversial

Issues with proteins in nutraceuticals/functional foods Isolation of effects- is the food component identified
really functional? Nutraceuticals/functional food proteins-DOSE/PURITY Purity problem - Phytates and minerals issue eg. iron
