I'm wondering what exactly the difference is between beans, lentils, grains, nuts, and seeds. For example, what's the botanical difference between black beans, green lentils, rice, almonds, and sunflower seeds?
1 Always take your vitamin D supplements with or right after you have eaten a meal. The food in your system will help your body to process this nutrient.  It doesnât seem to matter what meal you take your supplement with. The time of day does not appear to affect your bodyâs ability to absorb vitamin D.
It takes up to 48 hours to absorb the oil layer of vitamin D from 15 minutes of sun exposure. Showering or bathing will wash off the oil layer and you get little or nothing. Over 100 years ago, it was a weekly bath. 1000 years ago there was no bath.
