Vitamin D supplements – evidence for clinical effectiveness and safety

Vitamin D supplements

The claims about the usefulness of vitamin D supplements are all over the internet. And they seem trendy, as most pseudoscientific claims are these days.

The purpose of this article is to review some of the old and new information about vitamin D supplements. It’s about scientific articles that either support or refute a claim, that’s it. It’s not about what we believe or we do not believe, it’s about evidence.

I don’t think vitamin D is worthless. It is an important micronutrient for human health, and if there’s a chronic deficiency, supplementation may be medically necessary.

On the other hand, proponents of megadoses of vitamins, called megavitamin therapy or orthomolecular medicine (pseudoscientific terms to sound like they are based on real science), seems to work on the unscientific belief that if a little helps, a whole boatload will help a lot more. Most of these ideas have been debunked and are considered quackery and fads.

I wanted to take a look at the science of vitamin D supplements while examining its actual benefits to health compared to the possible dangers of excess supplementation.

Meat causes cancer? The answer is complicated and nuanced

eating meat causes cancer

Over the past few years, there have been numerous stories about whether meat causes cancer. Well, the answer is extremely complicated and nuanced, something doesn’t play well with clickbait headlines. People want to know The Truth™ about meat. Oh, and this article isn’t about vaccines, shocking, right?

A couple of years ago we were flooded by memes, articles, and uptight vegans laughing at everyone because the World Health Organization stated that eating meat causes cancer – that’s either processed meat, like a good French sausage, or unprocessed red meat.

Then recently, we were flooded by new memes, articles, and uptight vegans when an article was published to tell us that meat was safe. Of course, that was followed up by even newer memes, articles, and uptight vegans that that new article was junk, and meat causes cancer. 

Even those of you with good scientifically skeptical minds (which includes a lot of vegans) are wondering if anyone knows anything about meat and cancer. So I sliced some excellent French sausage and ate it with my GMO crackers – then this old avian dinosaur did what he is supposed to do, he read the articles.

So, should you worry whether meat causes cancer? I agree that there are a lot of issues about people eating beef, pork, and chicken for our individual health and for the health of the planet. But that’s outside of my bailiwick, and it will garner an incredible amount of yelling and screaming.

But I’m going to be brave (or not) and just try to answer the simple question of whether meat causes cancer. And here we go.
