Is vitamin D really bad for you?
You probably know that I'm a huge fan of vitamin D. After all the great information I've told you about it, I'm sure you're a big fan too. But not everyone is. A brand-new study says vitamin D and calcium are bad for your brain.
The authors did MRI scans on elderly subjects. They found that those who took more calcium and vitamin D were far more likely to have brain lesions in the MRI scans.
How can this be? After all I've told you about vitamin D, is it really bad for you?
Well, some of what these researchers found was right on target. But they missed the real cause of cognitive impairment. Let me explain.
Dr. Martha Payne from Duke led this study. Her previous studies demonstrated that high-fat dairy products increased the risk of brain lesions. But these studies also found that it wasn't the fat causing the problem. So Dr. Payne looked deeper. And now she's implicating calcium and vitamin D in vitamin D fortified foods.
She's absolutely right. But that still doesn't mean vitamin D is bad for you.
You see, dairy is fortified with vitamin D2. That's the synthetic form. It's not a healthy substance, and you shouldn't put it in your body. I don't even like to refer to it as vitamin D. If you are looking for vitamin D, be sure that it's the natural form - vitamin D3. But that's not the biggest problem with this study.
The biggest problem is that high-fat dairy foods are typically homogenized. This is a prescription for disaster. Your body uses bile to break down fat. Then it sends it to your liver for proper processing. Homogenization breaks up the fat into tiny particles. These particles are so tiny that they can get absorbed directly into your lymph and blood, bypassing the protective effects of your liver. This is totally against your body's physiology.
Furthermore, homogenized fat contains an enzyme called xanthine oxidase, a known destroyer of your arteries. Homogenization deprives your liver of the opportunity to detoxify this enzyme before it can damage your arteries.
Thanks to this study, you'll now hear the press tell you calcium and vitamin D are dangerous. But they neglected to tell you which vitamin D is involved and the impact of homogenization.
I've always believed dairy is for baby cows. You don't see baby cows homogenizing and pasteurizing what comes from mom's teat. But we do. That said, I do eat small amounts of organic fermented dairy and a bit of organic raw cheese. Don't be afraid to do the same if the rest of your diet is healthy. I can't deny that there is some benefit in eating dairy protein, especially for vegetarians. But if you drink milk or dairy products, make sure it's organic and raw.
And definitely keep taking your vitamin D3. Most people are deficient and need to take up to 5,000 mg daily. My favorite brand is Healthy Resolve. It comes in 5,000 mg tablets, so you have to take only one pill a day - instead of the usual five.
Yours for better health and medical freedom,
