There has been around 500 views of this thread since I first posted about magnesium, however no one else seems to want to comment. I wonder why. Are many embarrassed about what they eat? For many years I ate a poor diet that was lacking in vegetables and lacking in nuts and seeds, until I read about the large amounts of minerals and vitamins these have.
It was only in the past two years though that I started to seriously think about vitamin D. Since(theoretically at least) someone could get all the vitamin D they need from the sun, most people haven't even thought about taking vitamin D supplements. Those in northern areas though don't get that much in the way of strong sunlight containing plenty of UVB, and wear plenty of clothing when outdoors most of the year. Those in the north who have dark skin are particularly at risk for vitamin D deficiency. It might take someone with very dark skin up to 7 times as long to generate the same amount of vitamin D from the sun as someone with light skin.
I guess another issue is that the mainstream press has convinced many to take in plenty of calcium, but hasn't mentioned anything about magnesium.
The irony is that taking in plenty of calcium when someone is magnesium deficient may lead to bone loss, as the body needs to maintain a balance between calcium and magnesium. While my calcium intake hasn't been huge, it still probably was around 1200 mg a day. Even with my magnesium intake averaging something like 850 mg a day, I decided that I need to decrease my calcium intake to perhaps the 800 to 1000mg a day range. I decided to stick with Swiss chard instead of also eating spinach, as spinach has much more calcium.
"With a low magnesium intake, calcium moves out of the bones to increase tissue levels, while a high magnesium intake causes calcium to move from the tissues into the bones. Thus high magnesium levels leads to bone mineralization."
" The fact is that increasing magnesium intake increases bones density in the elderly and reduces the risk of osteoporosis. “Higher Magnesium intake through diet and supplements was positively associated with total-body bone mineral density (BMD)  in older white men and women."
"So they cannot get it through their heads that magnesium deficiency, not calcium deficiency, plays a key role in osteoporosis. "
