Striking a Balance between vitamin D & reducing your risk of cancer

It's not really a dilemma.

Just take a supplement. You won't get enough from the sun.

do they have a list? never seen one

linkuh?

Doesn't have a list but in the Editor's Thoughts on Vitamin D it says "If there's only one supplement you're taking for your health and your diet is decent, it should probably be Vitamin D. I highly recommend taking Vitamin D instead of a multivitamin most of the time."

I have 5000 IU bottle on my desk in work, I take 1 daily.

I don't believe the RDA is correct.

Even the FSAI said in their 1999 document setting RDA levels that while the RDA is defined as being more than an individual needs it is often regarded as the lowest acceptable intake for the majority of the population.

Please do , I would be fascinated how the body differentiates between the two. The fact that for both routes the compound is inactive and requires enzymatic hydroxylation by the livers and kidneys would suggest the body doesn't give a fupp where it comes from. But if you have evidence to suggest otherwise I'd love to hear it.

Can someone tell me what the RDA is?

Every time I look it up it's different. Some say X some say Y.

Can you take too much?

Low Vitamin One Sign of Sunlight Deficiency
A low vitamin D level found in the blood is one sign of sunlight deficiency, just like high blood cholesterol is one sign of eating too much meat and cheese. A far-reaching campaign has been launched by doctors, health organizations, supplement companies, and pharmaceutical industries to fix the problem of sunlight deficiency with pills.

Vitamin D Pills Are of Little or No Benefit and Some Harm. So What to Do Now?

According to popular opinions coming from friends, family, and physicians, most people are vitamin D deficient and in need of supplementation with pills. Evidence suggests that more than 40% of the world's population is vitamin D deficient (1). A recent report from a Scottish doctor found only 2% of his patients had a sufficient vitamin D concentration (75 nmol/L or above), and 47% had a severe deficiency (below 25 nmol/L) (2). Low vitamin D levels found in the blood are a clear indication that there is a worldwide problem of sunlight deficiency. Rather than correct the problem and encourage people to expose themselves to more of this natural element, the solution has become another drug — a supplement pill sold as vitamin D.

Worries over vitamin D, once known as “the sunshine vitamin,” have turned hundreds of millions of people into patients with worse, not better, health. The latest, and likely the final, analyses of the studies performed on treating people with vitamin D supplements has shown that this multiple billion-dollar business does not work. The authors, after thoroughly examining the results of nearly a quarter-million people from 46 major randomized trials, conclude: “Our findings suggest that vitamin D supplementation with or without calcium does not reduce skeletal or non-skeletal outcomes in unselected community-dwelling individuals by more than 15%. Future trials with similar designs are unlikely to alter these conclusions.”

Vitamin D supplements are so powerless that the benefits of supplements can only be seen at the extremes of need, such as with institutionalized elderly women (and even then the benefits are with a combination of vitamin D and calcium, not vitamin D alone).

I am going to do some research into getting a replacement bulb from a sunlamp to see if I could make some vitamin D from a sunlamp not sure it a good idea but I am going to do some research into it.

I'd be wary of that McDougall fella. He thinks most disease is caused by diet, including a stroke he had at 18. Meat is killing you, supposedly. He neglects to mention, for example, that the study about Vitamin D supplementation above was about massive yearly doses of Vitamin D all at once rather than spread out over the year. Also, those pictures of the planet earth trying to suggest that rank correlation with no exploration or actual data is all you need are a shitshow.

He also relies on selling treatment programmes through his own website, which has never been a good sign.

Well I be wary of any doctor or person who says diet does not cause or affect the progress of most of the top diseases: heart disease , type 2 diabetes, blood pressure ,stroke, many cancers,gout ,obesity, atherosclerosis and many more diseases.
And yes meat may be killing you ,I like to remind you that the World Health Organization has classified processed meats – including ham, salami, sausages and hot dogs – as a Group 1 carcinogen which means that there is strong evidence that processed meats cause cancer. Red meat, such as beef, lamb and pork has been classified as a 'probable' cause of cancer.

He does not neglect to mention, that two of the studys about Vitamin D supplementation was about massive yearly doses of Vitamin D all at once, he clearly states this in the article, this was not hidden in a link it was in the main body of one of the articles where you seen it, however there are over 30 articles referenced in the two links I referenced that questions how effective vitamin D pills are. Dr McDougall said" The benefits from taking pills are very limited and there are adverse side effects. The lesson is: Natural is best when it comes to food and sunshine. "

If you dont like what Doctor McDougall has to say perhaps you could look up Doctor Bob Clare full article at.

I’m skeptical about … vitamin D and calcium supplements.

Here’s what Dr. Joseph Mercola had to say about vitamin D (right beside his ad hawking a month’s supply of the stuff for $29.97): “There’s very few supplements I recommend for almost everyone but vitamin D is one of them.” And this from Life Extension Magazine: “Why isn’t everyone supplementing with Vitamin D?” Finally, from Dr. Mehmet Oz: “If I could think of one vitamin to push to everybody to get into their lives, it’s vitamin D.” Make no mistake, vitamin D is the “it girl” of the vitamin world—the sleek, sexy cure-all for falls, fractures, muscle weakness, heart disease, stroke, cancer, diabetes, asthma, and multiple sclerosis. A few years ago, on Good Morning America, Diane Sawyer stated that: “One-hundred million Americans have vitamin D deficiency. Think about it—one-hundred million of us, including children.” Americans listened, and now more than one-hundred million Americans are taking some form of vitamin D supplement. But if vitamin D is so great, then why did the USPSTF (US Preventative Services Task Force) recommend against using it at current doses in postmenopausal women to prevent fractures, the very group touted to have the greatest need?


Bottom line is there is a very big question mark as to how effective vitamin D pills are and the side effects they have.
