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...
