Vitamin C in Citrus Fruits Increase IGF-1 in Women

[Nelson Vergel]

"In conclusion, we found that women with higher intakes of citrus fruit and dietary vitamin C had higher circulating concentrations of IGF-I and lower concentrations of IGFBP-3. These results raise the possibility that higher intake of this fruit subgroup and its vitamin C constituent may be associated with a decreased risk of some cardiovascular diseases, at least in part, because of their influence on concentrations of growth factors."
