RE: RDAs

[Guest guest]

For reference, this is an excerpt from the following:

Food and Nutrition Board of the National Academy of Sciences :

From 1941 until 1989, the RDAs were established and used to evaluate

and plan menus that would meet the nutrient requirements of groups as

well as other applications such as interpreting food consumption records

of populations, establishing standards for food assistance programs,

establishing guidelines for nutrition labeling, to name a few. Their

primary goal was to prevent diseases caused by nutrient deficiencies.

Technically speaking, the RDAs were not intended to evaluate the diets

of individuals, but they were often used this way.

If you read the whole document, you would also read why they updated the numbers

and use the new DRIs , along with other identified levels, (avergaes, adequate,

minimal, etc)

http://www.iom.edu/project.asp?id=4574

" Responding to the expansion of scientific knowledge regarding the roles of

nutrients in human health, the Food and Nutrition Board, in partnership with

Health Canada, is updating the Recommended Dietary Allowances (RDAs). The new

title for these guidelines, Dietary Reference Intakes (DRIs), is the inclusive

name being given to this new approach. (Frequently asked questions about the

DRIs) "

The panels have covered the following groups of nutrients:

* calcium, vitamin D, phosphorus, magnesium, and fluoride;

* folate and other B vitamins;

* antioxidants (e.g., vitamins C and E, selenium);

* macronutrients (e.g., protein, fat, carbohydrates);

* trace elements (e.g., vitamin A & K, iron, zinc); and

* electrolytes and water.

So

1) to keep arguing the shortcomings of some guidelines, when the orginazations

that developed the guidelines, in and of themselves recognizes the

shortcomings of the guideleins and has now new guidelines..ts silly. Its been

along time since 1989.

2) to accept the shortcomings of the modern inactive society and its dietary

choices, and argue for the shortcomings, especially to those trying to follow a

CR-ON regime, (a group who already is way more interested, motivated in doing

what it takes,) is also silly.

Thats not what CR-ON is about, and its why there arent 20,000 list members. Its

not for everyone to try and scientifically and critiically evaluate the

literature to decipher the optimal diet, and to impliment it in their own lives.

Sure, every step in the right direction, should yield a level of improvement,

but, dont sell the " ON " short.
