Eat Smart for a Healthier Brain—Part II

May 5, 2013

While the modern American diet is increasing the incidence of obesity and diabetes, it is also wreaking havoc on our brains. Here are more “superfoods” you can add to your daily diet to help increase your odds of maintaining a healthy brain for the rest of your life.

Whole grains—Oatmeal, whole-grain breads, brown rice and wheat germ are just a few examples of whole grains that can reduce the risk for heart disease. They promote cardiovascular health, meaning good blood flow to your body’s organ system, which includes your brain.

Beans—Often unappreciated for its health benefits, the humble bean stabilizes glucose (blood sugar) levels. While the brain is dependent on glucose for fuel, it cannot store glucose.  It relies on a steady stream of energy, which beans can provide. Any beans will do, especially lentils and black beans.

Pomegranate juice—With its potent antioxidant benefits, pomegranate juice helps protect the brain from the damage of free radicals. And no part of the body is more sensitive to the damage from free radicals than the brain.

greentea2Freshly brewed tea—Tea contains potent antioxidants, especially the class known as catechines, which promote healthy blood flow.  In addition, the modest amount of caffeine in tea can boost brain power by enhancing memory, focus, and mood.

Dark chocolate—In addition to powerful antioxidant properties, dark chocolate contains several natural stimulants, including caffeine, which enhance focus and concentration, and stimulate the production of endorphins, which helps improve mood. It is best to limit your intake to one-half ounce to 1 ounce a day.

Being Overweight Can Affect Brain Function

July 7, 2012

Studies have shown that the brain appears to shrink more and age faster in overweight people. For example, in a study that compared brain images of people who were of normal weight with overweight (body mass index of 25-30) people of the same age, the overweight people had 4 percent less brain tissue and their brains looked eight years older than their normal weight counterparts. The brains of obese subjects (BMI over 30) had 8 percent less tissue and looked 16 years older. The loss of tissue depletes brain reserves and puts people at a higher risk of dementia and Alzheimer’s disease.

A long-term study of more than 6,500 people in northern California found that those who were fat around the middle at age 40 were more likely to succumb to dementia in their 70s. A Swedish study found that, compared to thinner people, those who were overweight in their 40s experienced a more rapid, and more pronounced, decline in brain function over the next several decades. Another study of 114 middle-aged people (aged between 40 and 66) found that the obese tended to have smaller, more atrophied brains than thinner people; other studies have found similar results. Pronounced brain atrophy is a feature of dementia. While our brains usually atrophy with age, research shows that being obese appears to accelerate this process.

We don’t know yet whether or no obesity-associated brain damage can be reversed. But those two old friends, a healthful diet and plenty of exercise, have repeatedly been shown to protect the brain. Foods like oily fishes and blueberries have been shown to stimulate the growth of new neurons. And whether you are fat or thin, young or old, the best hope you have of guarding your brain is to eat well and exercise.
