Can a low fat diet lead to vitamin D deficiency?

Answered on September 12, 2014

I'm just curious about whether there is any evidence to show that a low fat diet leads to vitamin D deficiency. Both my parents have recently been told to take supplements and I'm suspicious that their low fat diets is part of the cause.

My Mum has just been diagnosed with cholesterol and follows a conventional diet so I imagine her attempts to lower cholesterol will deplete her vitamin d levels even further. It's so frustrating to watch her make her health situation worse by the decisions she's making and the way she follows the doctor's advise without question

Just read that most of my fermented cod liver oil is D2 rather than D3 and the vitamin A/D ratio is much too high to be using that to supplement just for D (more of an A supplement.) Hrmm. Well, now I'm not sure how I feel about this, haha. Maybe the sheep's wool grease extract isn't so bad after all.

(most of the supplemental D3 comes from irradiated methanol-extracted sheep's wool grease treated to remove the non-d3 isomers, which I guess works fine, but kind of weird to eat that when you could be eating seafood or going outside more. There's vegan lichen d3, though, plants don't typically synthesize d3, so, I'm a bit of a skeptic without reading more about how the vegan d3 is produced. Though, any old d3 supplement works.)

Ah, interesting. I'm digging the cod liver as it comes from fish as a whole food with the vitamins in butter oil without any chemistry involved.. but any old D3 (cholecalciferol) supplement should work. There are a few analogs like D2, but, they seem a little sketchy / synthetic to me.

They've actually been getting more sun that normal lately as they've recently taken up golf & bought themselves a small yacht so it's strange to hear that they've both recently been diagnosed with vitamin D deficiency. They've recently been on weight watchers so I'm curious at whether their fear of fat has something to do with it. They don't eat a lot of fish because my Dad complains when Mum cooks it. He's not a big fan. We're of British heritage and live in Australia so out skin isn't all that dark. Is there a difference between the vitamin D supplements that you can buy?

except for the bit about only needing 10 min of sun, it's a pretty decent article.

I really like this article from stephan guyenet at wholehealthsource: http://wholehealthsource.blogspot.com/2010/04/magnesium-and-vitamin-d-metabolism.html

I'm no expert but it seems like vitamin D absorption is really complicated and even popping a lot of it and getting your levels up might not be the best thing. Everything (K2, A, D3, Calcium, Magnesium, Boron, etc.) affects each other and helps regulate your levels and absorption properly and effectively. From the link above:

Ted Hutchinson posted a link in the comments section of my last post, pointing to a page on the Vitamin D Council's website where Dr. John Cannell discusses cofactors required for proper vitamin D metabolism. It's actually the site's home page, highlighting how important he feels this matter is. In this case, 'cofactor' simply means another nutrient that's required for the efficient production and use of vitamin D. They include:

???Magnesium ???Zinc ???Vitamin K2 ???Vitamin A ???Boron And probably others we aren't yet aware of.

Also check out:

http://whole9life.com/2012/02/what-about-calcium/

and this one

http://wholehealthsource.blogspot.com/2008/10/vitamin-d-its-not-just-another-vitamin.html

The last post has a part 'How to be vitamin D deficient' - that applies in particular to your parents.

Absolutely. Vitamin D is a fat-soluble vitamin

Fat aids in the absorption of vitamins A, D, E, and K, so yes.

I'm curious how much sunlight your parents get on a regular basis and their skin tone. I don't tend to think of fat/carbohydrates/protein ratios as affecting your vitamin D levels so much as specifically how much D you're eating and how much you're synthesizing (though eating more cholesterol and being younger / fairer skinned would help optimize your synthesis routes.) Eat more / synthesize more, and you'll have more D regardless of how much fat you put in.

If they don't go outside (or block the sun when they do) and don't eat things that contain vitamin D, then yeah, they need more D through supplementation. (Do they eat much seafood?)

I like the way 15-20 minutes a day of afternoon sunlight, daily fermented cod liver oil, and seafood a few times a week feels. I think you could do this and stay low-fat.

Possibly. But many folk don't get enough sun exposure due to misplaced melanoma fears.

Low protein correlates with D deficiency, as well.

In any case, make sure they are taking a D3, oil-based supplement and have them get levels tested again in 3 months. Optimal blood range is 50-60 ng/ml.

Yes ... it's always good to find a happy medium and eat some healthy fats :)
