I just got my blood results back (over the phone, don't have the paperwork yet)
And the main problem (actually the only problem) was a low Vitamin D count.
So I was a little pissed but very soon it hit me.
I was looking at is as a weakness. Why do I have to supplement and other people (SAD eaters) don't?
But the real truth is that SAD eaters do get Vitamin D supplements.
And they get them all the time.
Apparently there are not enough food sources to assure a good level of Vitamin D. There are only a few food sources that contain Vitamin D.
Fatty fish, wild salmon, cod liver oil, some mushrooms.
So to ensure people get enough vitamin D it is added to all kinds of foods.
Like dairy products, cereals, flour, baby foods, some brands of orange juice.
All kinds of foods that we vegans do not eat.
So it is not abnormal that those of us who do not live in a very sunny climate might need to supplement.
