Ain’t science great?!!!

Researchers at Tufts University were investigating the effect that Vitamin K supplements have on the bone mineral density and vascular calcification of a group of 355 non-diabetic men and women aged 60 to 80.

However, during the course of their 3 year study, they found that the participants who received the Vitamin K supplement had a noticeable improvement in their insulin resistance.

And as you already know, insulin resistance  is one of the major factors driving America’s obesity epidemic.

And if you didn’t know: read this, this and this.

STUDY DETAILS

Among the participants given vitamin K, both men and women took daily multivitamins containing 500 micrograms of vitamin K, five times the Adequate Intake (AI) recommended by the Institute of Medicine’s Food and Nutrition Board, with instructions to maintain normal diets without any additional supplementation.

They also received a calcium and vitamin D supplement.

Men and women in the control group received no vitamin K supplementation but did receive the multivitamin and the calcium and vitamin D supplement.

For the present study, insulin resistance was assessed by the homeostasis model (HOMA-IR).

Additionally, participants’ blood glucose and blood insulin levels were measured following a minimum 10-hour fast.

In addition to improved insulin resistance, the supplemented men had lower blood insulin levels compared to the un-supplemented men at the conclusion of the study.

CONCLUSIONS

The researchers concluded that Vitamin K supplementation for 36 months may reduce progression of insulin resistance in older men.

And why would Vitamin K have an effect on insulin resistance?

The researchers theorized that vitamin K may improve insulin sensitivity through suppression of inflammation.

Aaahhh, our old friend inflammation.

Isn’t it funny how our Western diet, inflammation, obesity, insulin resistance and diabetes keeping showing up in the same places

    It is useful to know that consuming Vitamin D is useful for treating chronic pains. Since a lot of diseases engage painful conditions and in some way or the other, are triggered off by not enough vitamin d, supplementation of vitamin D can help resolve the issue.

    Obesity is really an epidemic these days. People have become very lazy and does not want to exercise anymore. I do a lot of jogging and brisk walking everyday just to be fit and healthy.

    Wow, I’m glad I eat green leafy vegetables daily and cabbage & cauliflower very often. I’m wondering what kind of cereals they are talking about, and I’m guessing they mean whole grains like brown rice, millet, barley, etc.

    I liked the video! Thanks.
