there is the sodium/potassium balance in the body. In summer it is natural to have a greater consumption of potassium than sodium cause of all the fresh produce being consumed. This is primal from before modern transporation. Now, in winter, we can eat potassium rich foods like bananas and that really confuses the body into thinking it's still summer. Following from this the Vitamin D in the liver does not go to the kidneys to get multiplied like it would if sodium were the dominant like it would in winter. So we really have to take vitamin D here in the north lands in winter, unless we can get some liver of a fish, or we eat a primitive diet without fresh foods.. dried foods would be necessary..
