What do you mean by macro nutrients?

Usually, when discussing human diet: carbohydrates, fat, and protein. These comprise the energy content of food.

Ok, just what I thought. But how does processing destroy them?

Vitmans and minerals are the easiest thing to supplement in foods, and are everywhere. Macro nutrients are what processed food loses.

What do you mean by macro nutrients?

He means phytonutrients. Those components of plants that are more complex than protein, carbohydrates or fats and which are known to extend human life by largely unknown processes.

I used to eat the gummy vitamins like candy, I got Hypervitaminosis, and my hair started to fall out. I thought I had a horrible disease. Then we figured it out. It wasn't much fun.

Ignored the "Do not exceed the recommended dosage" warning eh?

They taste SO good.

I don't feel this is a very good article. IMHO the key to understanding vitamin supplementation is first, to know which are fat-soluble (and will be stored by your body) and which are water-soluble (and will be flushed by your body when you urinate). So, it is almost impossible to over-dose on Vitamin C, since, your body will easily eliminate anything it doesn't need - C is water-soluble. This article covers the diff…

In school, I was taught a mnemonic for fat soluble vitamins: DEAK. In other words, you want to "deke" [1] out of the way from these vitamins. You want to watch how much of vitamins D, E, A, K you ingest because they are fat soluble and you can easily overdose on them (unlike vitamin C). It's not a catch-all but it helps when you are taking vitamins.

[1] it's a play on words and a homonym, "deke" comes from hockey where you dodge or fake out an opponent to get around them. It must be the Canadian school system further injecting hockey into our lives. :)

To hell with Vitamins. Eat fruits and vegetables.

Nice idea. In practice, if you live in a large urban area, especially in warmer climates, by the time those fruits and vegetables get to your plate, they'll have far fewer vitamins than you'd expect.

Back when I lived in Jakarta (very large urban area, very warm) I used to get mouth ulcers constantly, despite eating more than my fair share of fruits and vegetables. The solution, according to the family GP, was to supplement vitamin C. Yeah yeah, n=1 (well, n=a family of 5, but still), but it worked and seemed to lend some validity to this theory.

Everything I've read about this in recent years seems to boil down to one simple rule of thumb: Supplement vitamin D and forget about everything else.

EDIT: As per the article, children need A, C, and D, and women wanting to get (or who are) pregnant need some other vitamins.

But yes, mostly don't bother with anything apart from D.

Solubility is important but even though vitamin c is soluble, taking too much is quite harmful aggregrated over longer time frames. http://m.theatlantic.com/health/archive/2013/07/the-vitamin-...
