I call crap on this. I was diagnosed with type 2 diabetes earlier this year. I eat more cheese and drink more milk than any 2 other people, plus I take daily supplements.
Maye it's more helpful in women?
Or just Asian women?
Maybe it has been helpful to you, and if you had not had a higher level of D in your diet you would have developed diabetes sooner?
Perhaps it's an ‘all else being equal’ for people who are insulin resistant, vitamin D is helpful.
Just speculatin’.
Please check the details.
The dosage noted is far in excess of what can be received from diet. The source of Vitamin D is not diet,it is manufactured by the skin as a result of exposure to the sun.
Recent study reveals that the vitamin D added to milk is barely adequate to prevent rickets in children. Vitamin supplements also contain lower levels than the 4000 units in the study.
Did they check your level of Vit D?
They have founbd that even that isn’t enough. I have been a type 1 since I was 9yo and earlier this year my new doc tested me for vitamin D. Even though I drink milk eat cheese and yogurt I was still extremely low on vtamin D. They think it has something to do with the way diabetics absorb the vitiman and we really do need some extra. I was on 50,000IU a week but now am just using an OTC with 2000IU per day.
Get the 25-hydroxyvitamin D, aka 20[OH]D, test done. Find out if you are deficient. Type 2 diabetes is thought to be multifactorial in nature. IIRC, over two dozen genes have been implicated in type 2 diabetes. This study was limited to: "The new study involved 81 South Asian women with insulin resistance living in New Zealand." People of color living in temperate climates are routinely found to be deficient in vitamin D.
A quart of fortified milk is only supposed to have 400 international units of vitamin D, IIRC. That level is still the recommended daily allowance, but many now suspect that level to be far below what is needed. (Search the keyword vitamind. I posted at least a two articles about that.)
Vitamin D in foods: development of the US Department of Agriculture database.
abstract excerpt
The Nutrient Data Laboratory has prioritized foods for analysis and has identified the following as important contributors of vitamin D: finfish and shellfish, naturally occurring sources, and fortified foods such as milk, calcium-fortified orange juice, breakfast cereals, American cheese, margarines, and yogurt.
Adequate levels of vitamin D may not be sufficient to avoid type 2 diabetes. Insulin resistance is also associated with obesity.
Frankly, I can hold my left hand out the sidewindow to signal a left turn and will get 50% of my annual D requirement in the time it takes to pull my hand back in.
I suppose I could eat more raw fish liver ~ which sounds pretty good at the moment ~ or carry around one of those polished steel mirrors under my coat so I can stop for a sunbreak at Noon in the winter.
Your typical South Asian Woman has a good tan with lots and lots of Persian genetic background. They may need more vitamin D.
My daughter was found to have extremely low levels of D, so her doctor prescribed a massive dose for several weeks. Months later, when she was re-tested, her level had already dropped too low again. Perhaps some people have more trouble maintaining a good level of D than others do. I’m always bugging her now to spend more time in the sun and take supplements. (Hey, I’m a mom... it’s what I do!)
