US FDA recommends daily value of 800 IU per 2,000 IU of calories
DV of Vitamin D = 20 micrograms = 800 IU will be on US food labels in 2020
It is the MINIMUM amount to maintain health
The amount recommended is proportional to the actual calories consumed
Many people consume >3,000 calories/day
Many tall people consume >3,000 calories/day
Most counties now consume >3,000 calories/day
Daily value replaced Recommended Daily Allowance (RDA)
Daily value increases with the number of calories consumed.
The RDA was not proportional to calories consumed
