Chablis, or not chablis? That is the question

From the way some people talk about alcohol, you might think it’s almost a cure-all, capable of preventing heart attacks and strokes while reducing the risk of Alzheimer’s disease, diabetes and macular degeneration.

Others, however, will tell you alcohol is bad for your body and brain, causing addiction, cirrhosis of the liver and abnormal heart rhythms while raising the risk of breast cancer.

So who is right? Well, both sides, actually.

A growing body of research suggests that, when consumed in moderation, alcohol can have many significant health benefits.

The evidence purporting that alcohol may be associated with a reduction in heart disease – or at least a reduction in deaths from heart disease – has garnered the most attention.

One recent study of former teetotalers found that those who took up drinking wine in middle age experienced a 38 percent reduction in heart attacks and stroke over four years.

“The findings suggest that, for carefully selected individuals, a ‘heart healthy diet’ may include limited alcohol consumption, even among individuals who have not included alcohol previously,” the study’s authors wrote.

Got your genetic test results? Do tell

If you’ve received your Navigenics genetic test results, it may be time for “the talk.”

Time to have a candid conversation with your physician about your DNA and what you can do to improve the future direction of your health.

This summer, I blogged about some of the barriers patients might face in sitting down with a physician to go over the results. Fear of discrimination and too-short appointments are foremost on some people’s list.

Yet your doctor can be your greatest ally in your quest to make informed decisions about your health.

And, as one of our satisfied customers relates, having that conversation can be one of the most important steps you can take along the path toward optimal wellness.

In Patrick’s case, it meant early detection and early treatment of a health condition that might otherwise have gone undetected for some time.

Don’t let this healthy catch get away

An apple a day isn’t enough anymore. Now you also need to think fish or flaxseed in your diet to help keep the doctor away. That is why Navigenics has new recommendations to encourage our members to be sure they get enough omega-3 fatty acids in their diet.

Omega-3 fatty acids aren’t snake oil, promising to cure all ills; rather, they are oils from fish or certain nuts and plants, and researchers have found strong evidence that they have many potential health benefits.

These polyunsaturated fatty acids are found primarily in fish and fish oils, but also in some plant-based oils, such as canola oil or flaxseed oil, and certain leafy green vegetables, including spinach, kale, broccoli and seaweed. They are essential to human health, but cannot be made by the body. That is why it is so important for people to make sure they get sufficient amounts of them through diet or supplements—and to know how much they need.
