vegetables and the effect...
Estimated folate intakes: data updated to reflect food fortification, increased bioavailability, and dietary supplement use
NHANES III humans estimated average requirements
2016/6/1
There is a critical need to estimate dietary folate
intakes for nutrition monitoring and food safety evaluations, but
available intake data are seriously limited by several factors.
Interest in carotenoids has increased over the past decade
from scientists involved in a variety of disciplines. Although
some human nutritionists have focused their efforts on the potential
role o...
The title and conclusions of the article, “Bioavailability of iron glycine as a fortificant in infant foods,” by Fox et al (1) are not supported by the data presented. Their data show that the absorpt...
