However, as I study nutrition, I think perhaps a bigger reason we are so nutrient deficient is a result of the sugar we eat. The chemistry of sugar in the body is quite alarming. If you eat much sugar (and it doesn't take much) your are probably deficient in Magnesium, Calcium, Vitamin D, Vitamin C, and Chromium. Research shows that for every one molecule of sugar, you need to intake a minimum of 7 and perhaps as much as 40 molecules of magnesium. That is a big deal considering that magnesium is responsible for promoting healthy sleep, relaxing muscles, healthy, regular bowel movements, and the big one...blood sugar regulation. No wonder diabetes in on the rise. Magnesium is hard to get in our regular diets. Then we compound that by eating more sugar than any other generation. My FAVORITE talk that illustrates this can be viewed here.
Sugar also causes vitamin D deficiencies. It produces an unhelpful enzyme that destroys vitamin D. In previous times that worked because people at sugar in fruit in the summer when people were outside getting lots of extra vitamin D. Now we just eat it all year long, without adding the extra vitamin D. Calcium absorption is linked to vitamin D supply. With low vitamin D levels, calcium will be low also.
It is clear that we need to lower our sugar consumption. The momentary pleasure is just not worth the long term effects on our body. However, we must be honest. That is really hard to do and even harder to get our kids to do. With our best efforts(which are still worth making), we will still need to supplement. When wondering whether to supplement, or not to supplement...read all the links above!
