The problem with spinach is that the oxalates bind up the minerals, at least they do with iron and calcium, not sure about magesium. Yes, those numbers look impressive but the amount you actually end up with is much, much less.
Beans have a similar problem with phytic acid and lectins.

Phytic acid is a strong chelator of important minerals such as calcium, magnesium, iron, and zinc, and can therefore contribute to mineral deficiencies in people whose diets rely on these foods for their mineral intake, such as those in developing countries.[6] It also acts as an acid, chelating the vitamin niacin, which is basic, causing the condition known as pellagra. [7] In this way, it is an anti-nutrient.[1] For people with a particularly low intake of essential minerals, especially young children and those in developing countries, this effect can be undesirable.

I think you're obsessing over taking magnesium with vit d. I just haven't heard of anyone credible saying that this is something you have to do. Many people have lived in bright sunny climes and gotten a lot of vit. D without ever having to worry about taking magnesium or calcium supplements. How do you suppose all those lifeguards manage to survive a summer? |
