How To Improve Your Brain Fitness?

Most of us are concerned about staying sharp mentally. Mind games are designed to exercise your brain. There are mobile apps such as Luminosity and Fit Brains claim to boost cognitive ability and ward off mental decline.

Do they actually work?

David Linden a professor of neuroscience at the John Hopkins School of Medicine doesn't think so. He says "the effects are small and don't last very long."

So if the games don't work what does?  Dr. Linden believes that the best way to maintain mental fitness is with physical exercise. "Walking 30 minutes a day has a greater effect than playing any brain game. Even moderate, low intensity exercise is five times more beneficial to cognitive tasks than playing brain games on your iPad" he says.

Research has shown that exercise increases the volume of the brain and elevate patters of activity. The effects are especially beneficial for middle aged people.

The bottom line is clear. Exercise your brain by exercising your body.

How To Find Whole Grains in Your Food

We all know that we should be eating more whole grains and less refined flour. The U.S. Dietary Guidelines advise that at least 50% of your daily grains should be whole grains. The goal is clear. The problem is how do you know whether you are getting enough whole grain in your diet?

Food labeling is confusing. In fact the food industry goes to great lengths to make it difficult for the consumer to understand the nutritional value of many foods. Iy is easy for them to mislead us. For example bread that is baked with wheat flour. This sounds good but all flour is wheat flour. The flour used may be white flour, refined flour or enriched with some vitamins and minerals. Yes it is wheat flour but not whole wheat and   certainly  not be whole grain.

A study from Harvard published in Public Health Nutrition looked at 545 grain products and reported that the most reliable way to determine the overall carbohydrate quality was to use the ratio of grams of total carbohydrate to grams of fiber. To qualify as whole grain the ratio should be about 10 to 1. To make the math easier multiply the grams of fiber in a product by 10. The result should be more than the grams of total carbohydrates.
