Upper intake nutrient limits have recently been update, but (thus far) no specific recommendations have been made.

The following articles appreaed in J. Nutr. 136:490S-492S, February 2006, and give us little bites of what the American Society for Nutrition is up to:

Setting Tolerable Upper Intake Levels for Nutrients

Toxicology of Micronutrients: Adverse Effects and Uncertainty

A Critical Assessment of the Upper Intake Levels for Infants and Children

Evaluation of Dietary Intake Data Using the Tolerable Upper Intake Levels

Gap Analysis Guidelines for Assessing Acute, Chronic, and Lifetime Exposures to High Levels of Various Nutrients

Overall Discussion: Gaps and Suggestions

It would be interesting/useful to look at the numbers of specific nutrients, but I don't have access to the full-text articles. This will be a wait-n-see. If some of these findings are important to public health, the popular science press and the USDA should release their own reports soon. Stay tuned...

The British govt. has established their own Safe Upper Levels (SULs):
