The Best Health and Fitness News
1. Could barbecuing your food put you at risk for Alzheimer’s and diabetes?
That’s what a new study in the Proceedings of the National Academy of Sciences is suggesting. They found that heats cooked at higher temperatures such as grilled our broiled meats contain by products from meat/fat/sugar reactions that increase the risk for those diseases. The study also found that foods like pasta, pastries, cakes, biscuits, white bread, cheese, and eggs, might also play a role in increasing these compounds. So what’s safe? Cooking foods at lower temperatures and avoiding processed carbohydrates.
2. In other news (and related to the above story), a diet high in carbohydrates is linked to dementia and Alzheimer’s.
3. Can too much selenium and vitamin E be a bad thing?
You betcha. Both selenium and Vitamin E are potent antioxidants. Selenium at one point was looked at for a way of lowering the risk of prostate cancer. But what about supplementation with selenium and vitamin E? The study found that men who had high levels of selenium before they began supplementation (in other words already healthy individuals) increased their risk of high-grade prostate cancer by 91%. For those with low selenium levels who supplemented with Vitamin E, the risk of high grade prostate cancer increased to 111% percent. The bottom line of the study: for those that have a healthy baseline of nutrition, you likely don’t need to supplement your diet with extra selenium or vitamin E. A multivitamin should do just fine.
4. How much do you sit?
According to a study from Northwestern Medicine, if you’re over the age of sixty, every hour you spend sitting is linked to doubling the risk of being disabled regardless of how much moderate exercise you get. For example, if one woman sits for twelve hours a day, and another for thirteen hours a day, the twelve hour woman is fifty percent more likely to be disabled. Get up and move. Never stop moving.
5. And there is some good news… the obesity rates between two to five year olds dropped according to the Journal of the American Medical Association. The rates fell from 13.9% to 8.4%.
The Worst Health and Fitness News
1. How important is looking good to you? A good facial hair surgery is just as much as breast implants. The trend in New York that has people paying $8,500 for facial hair transplants.
A poorly designed study to come out of Uppsala University found that saturated fat builds more abdominal fat and less muscle than polyunsaturated fat.
A poorly designed study? You betcha. Saturated fat does have it’s benefits (such as raising HDL cholesterol). But why was this a bad study?
It only involved thirty-nine people. While both groups consumed an equal amount of extra calories throughout the day, the difference was in the vehicle. The saturated fat of choice was palm oil. Also, the vehicle for the extra calories was designed in the form of muffins. If the delivery method was different for the saturated fat, such as animal fat, would the results be the same?
Another key point missed is that the other group that didn’t develop as much abdominal fat used sunflower oil. While sunflower oil is made up of polyunsaturated fat, it has high amounts of omega-6 oils which are inflammatory in nature. High inflammation is a huge risk for heart attacks and strokes.
The moral of the story: not all studies are equal.
Until next week…
