[edit] Conflicting Info

this article recommends saturated fatty acid intake be limited to "as few as possible" but the Healthy Diet article states that a sufficient quantity of saturated fatty acids is "necessary". they cant both be right.... —Preceding unsigned comment added by 76.174.33.232 (talk) 05:52, 17 September 2007 (UTC)

[edit] Correction

I thiink the person who made the switch (edit) recently from 0.9 mg copper to 90 mcg copper was off by a power of 10 in their conversion. 65.78.17.194 13:05, 7 October 2006 (UTC)

Thanks for paying attention. I believe there was an error in the earlier text. I double checked this against the cited table, and think it is now correct.M dorothy 04:52, 9 October 2006 (UTC)

What is the difference between the Estimated Average Requirements, Reference Daily Intake, and Adequate Intake? -- Beland 20:28, 16 June 2007 (UTC)

The EAR is the amount of a given nutrient that meets the needs of half of a specific healthy population (the average person). The RDA is the EAR + 2 standard deviations. Thus it is the amount of a given nutrient that meets the needs of 97.5% of a specific healthy population. The EAR is used more often to evaluate how many people in a population are meeting their needs for a nutrient. The RDA is more often used for individual recommendations.

[edit] misleading

The Dietary Reference Intake is a system of nutrition recommendations from the United States Department of Agriculture intended for the general public and health professionals. Applications include:

   * Food labels in the United States and Canada

This maes it seem like the United States Department of Agriculure can implent govermental decisions in Canada. Someone should elaborate if anyone knows anythign abotu the subject.f

[edit] Macronutrients

There should be a note for the RDI/AI of protein (listed as 56g/day) referencing the debate among weight trainers, bodybuilders, nutritionists and medical professionals concerning the necessary daily intake of protein--as well as a reference to the omega-6 to omega-3 ratio, heavily problematic in Western, particular American, diets, which is suggested in this chart to be the the typical 10:1 ratio (some sources insist on a 4:1 ratio or less).

[edit] Omega-6 to Omega-3 ratio

Hasn't it already been determined that the 17:1 ratio typical to the American diet is unhealthy and that the >4:1 ratio is preferable?

[edit] Zinc

The UI for Zinc is listed as 40 mg; could it maybe be appropriate to include a footnote that for some individuals 50 mg is a sufficient UI?

[edit] Quantity

I think that 130 g carbohydrates is for a dog, but not for a human. A human should consume at least 8.8 MJ/day. Of that energy, 55 % should constitute carbohydrates (300 g), 15 % protein (80 g) and the remainder should be fat. That is what professionals say. I would say, that the fat intake could be a little bit less, if someone is inactive (8.8 MJ/day), or a little bit more, if someone is very active (e. g. bikers, having energy output up to 25 MJ). Further, if someone is recovering after some stress, e.g. cancer, rheumatoid arthritis, intensive psychical or physical strain etc., protein intake should be at least 140 g, but better 160 g. When my resting heart rate was 36/min (after 100 km on bike), my protein intake was more than 120g/day. —Preceding unsigned comment added by 195.113.65.9 (talk) 19:54, 13 October 2007 (UTC)
