1. I used to get sick (catch a cold or feel like I was coming down with one; I don’t mean sick to my stomach) if I’d work out at the gym after skipping lunch, even if I had a good breakfast. I recall one time when I worked out under those conditions, then sat down at my computer to do some work until I became hungry. After an hour, I was not hungry yet. But after an hour and a half or two, my vision started to black out in the center, so that I couldn’t see what I was typing. At that point, I made dinner!!
But since I changed my diet and started taking vitamin D3, this no longer happens. I can skip breakfast and lunch, then work out, and be fine for hours — no blacking out of vision, no getting sick. What’s more, I can fast for 24 hours, but stay energetic and clear-headed. Once upon a time, I never would have thought I could fast that long, and never would have tried. And I used to hate, hate, hate to go to bed hungry. Now sometimes I *want* to go to bed hungry.
2. In tutoring students, I am around students who are sick, of course. But, recently, I have not come down with anything. I know I have picked stuff up from some students because one weekend I had two periods lasting about half hour to an hour where I was sneezy and feeling like I was coming down with something. But I never did. This was a shocker; in years of prior experience, feeling like I had those two times always had led to being sick. The only/major differences between now and then are vitamin D3 and diet. On the recent days when I was around students who were sick, by they way, I increased my dosage of vitamin D3 to 6,000 to 10,000 IU. (I recently bought some vitamin C, with 1,667% of the “recommended” daily amount; I save it only for days when I’m around someone who is sick.)
In other words, that’s “not getting sick, courtesy of science and mathematics.”I take 2,000-5,000 IU per day of vitamin D3, unless I’m going horseback riding, in which case I don’t take any — I get plenty of vitamin D made by body + sunshine. (In a prior blog post, I linked to a vitamin D calculator, which you can check out, if you are interested.) Vitamin D is supposed to be best taken in conjunction with vitamin A and vitamin K2. They work together. Dr. Guyenet discusses this relationship in a number of places, such as a blog post about osteoporosis and a post about vitamin toxicity. Dr. Eades and Dr. Harris have written some very good articles regarding H1N1 (swine flu), the flu generally, and vitamin D:
H1N1, Vitamin D3, and Innate ImmunityDr. Eade’s Website and Dr. Harris’ Website, of course, but also:
1. Art De Vany’s Website/Blog. I love this one, but it’s more technical — you need to know some math and science.
2. Mark’s Daily Apple. It is a little more accessible to the general reader.
3. Whole Health Source. This blog is also technical. The author is a PhD in neurobiology, and writes accordingly.Of course, the standard “caveat” applies: judge for yourself. Read the blogs/Websites if you want; ignore the blogs/Websites if you want; read the Websites/blogs and see what you agree with and don’t agree with, if you want. I think that all this information is a great addition to teaching math and science. There are good content *and* methods involved. It’s all a treasure trove of information that shows the practicality and importance of math, science, and reasoning generally.
