Some of the added nutrients include iron, vitamin A, iodine and folic acid.
One cup of kale (boiled, but not overcooked) gives you double the DV for vitamin A. You'll also get some vitamin C, a small amount of B vitamins and a generous amount of calcium.
Studies of neonatal supplementation with vitamin A have yielded contradictory findings with regard to its effect on the risk of infant death, possibly owing to heterogeneity between studies.
