Might as well make this an answer. ...it seems to collapse when I rub my foot on it. As @tyersome stated, it appears to be salt, not mold. Salt crystals would definitely collapse easily underfoot, and should be mostly quite dry, whereas mold would be... maybe squishy (?) but likely unpleasant in some way. Mold also smells, which you haven't mentioned, ...

Part of this depends on the exact nature of "salt depletion" you're referring to. I have never actually heard of a case of hyponatremia being caused by low consumption of salt. We don't need to consume NaCl. It's present in the foods we eat in adequate amounts. We may want to salt our food, but it's not necessary for life. Hyponatremia is an ...

Your understanding is correct to some extent. Tooth enamel mostly consists of a mineral called hydroxyapatite ($\ce{Ca_{10}(PO4)6(OH)2}$) (Staines et al, 1981). Though this makes enamel the strongest material in the body, it is susceptible to degradation. In acidic environment, hyrdoxyapatite gets dissolved and leads to cavities (Brown, p. 688). The ...

Iodine is naturally found in sea water and soil but it is not evenly distributed, with many areas in the world with low levels of iodine. Iodine accumulates naturally in fish, and plants growing in iodine-rich soil. Mammals that eat these plants get iodine from them, which then accumulates in the milk, making dairy and its products (e.g. cheese) another ...

I think the piece of missing information here is the distinction between macronutrients and micronutrients. The info from Mayo clinic quoted in the another answer addresses some reasons why whole foods might be better than pills for obtaining micronutrients (i.e. vitamins and minerals). While this may be true, most of it remains to be conclusively ...

News to me is that about 4500 of the 4900 minerals on Earth have been created by life. After reading the article, this isn't what was said. What was said is that life increases mineral diversity on a planet, most notably through biproducts reacting with existing minerals (like Oxygen - a biproduct of photosynthesis - reacting with iron to create iron-oxide)...

Biosilicification is a good search term to use. The silicic acid present around the roots can be actively transported into roots, and later into specific cells or cell compartments. It is deposited preferentially onto lignin or polysaccharide surfaces. For free articles giving an overview there is: Nawaz, Muhammad Amjad et al. “Phytolith Formation in Plants: ...

If your body was filled with highly specialized bacteria living in nutrient-rich conditions, what you suggest could happen*. But in practice, you're not filled with such bacteria, and most of the bacteria in your body are living in rather harsh conditions for rapid metabolism. That said, gut bacteria do produce a range of other useful nutrients. Look for ...

TL;DR : Food gives the human body much more than simply vitamins & minerals. A healthy diet is essential to overall healthiness, not just this one aspect of it. Micronutrients The component you're asking about - vitamins & minerals - are referred to as "micronutrients", and is only a quarter or so of what the body needs. Micronutrients are the ...

The Question: Why can't we just take enough pills to obtain these vitamins and minerals? We don't know enough about nutrition. There are about 45 essential nutrients, which you need to consume to be healthy and live. You can get all of them from food without thinking about them. I'm not sure if currently there are a lot of supplements on the market that ...
