Answer 1

Answer- Average consumption in the united states does not meet the recommended intake.

The adults living in southern united states needs the high amount of dietary vitamin D because in those region there is risk of developing vitamin D deficiency due to less exposure of UV B light (290 nm -315nm) especially during winter season.The lifeguards on southern beaches don't have risk of vitamin D toxication because provitamin D3 and vitamin D3 absorbs the sunlight and converts it into the photoproducts in them.VItamin D is fat soluble and it should be taken with meal in order to improve absorption by around 50 % compared to empty stomach.The bioavailability of vitamin D from soy milk(plant based milk substitutes) is high as 237 ml soy milk provides the 107 to 117 IU of the vitamin D.
