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.
In the final stage of the process, the liver and kidneys convert that vitamin D into yet another form of the vitamin -- vitamin D3, the active form of the vitamin that our bodies can use. You need just 10 to 20 minutes of sunlight a day to ensure that your body is producing enough vitamin D. After we reach our seventies, the precursor to vitamin D generally found in skin diminishes three- or four-fold, making it increasingly difficult for us to produce vitamin D naturally.
