Four kinds of ways to make the brain to become smarter

The brain accounts for 2% of body weight, but calories a day consumed 20% of the body. The average brain weight of about 1,200 grams, was loaded with 100 billion neurons. So how nutritional supplements can make the brain more clever? British and American scientists in the "Fun Science" Web site published an article, listing the following four methods.

First, Shaochiduocan. The brain's energy needs can not be too much nor too little. In order for the brain power to obtain idealized British Aston University professor Michael? Green proposal "Shaochiduocan." The best state in the working brain, blood flow, there should be about 25 grams of glucose, which is equivalent to the total amount of glucose in a banana. Therefore, the work at any time to add a banana might be a good choice.

Secondly, eating a low glycemic index food. Glycemic index (GI) refers to the food enter the body within two hours of the relative speed of blood sugar. Salty crackers allow rapid blood sugar rise, and its glycemic index will be high; raw carrots to the slow rise in blood sugar, and its glycemic index is very low. Low-index foods, carbohydrates break down into glucose molecules slow the brain's energy supply more stable. High-fiber carbohydrates, glycemic index is relatively low, for example, fiber-rich whole-wheat bread, black low-glycemic index, elevated blood glucose will not be too drastic. We can add some meat or bread in the egg, add a little olive oil, this lunch Youziyouwei, while giving the brain a sufficient supply of nutrients.

Thirdly, multi-unsaturated fatty acid intake. Although fat can reduce the glycemic index of food, but not all fats are the same. Fast food commonly found in the worst trans-fatty acids, saturated fatty acids is not how, unsaturated fatty acids is most healthy. Roehampton University in the UK benefit? Gibson said: "The diet rich in saturated fatty acids in cognitive deficits occur more easily." Experiments show that a large number of consecutive weeks intake of saturated fatty acids in mice, in charge of their memory function in the hippocampus would be damage. In response, Green analysts say Take omega -3 fatty acids, it has been proved useful in depression and other mental diseases, but also good for the development of children's brains. But the omega -3 fatty acid preparation on the role of the brain of healthy adults remain controversial. In addition, the intake of unsaturated fatty acids is still the best way of food, such as deep-sea fish, seeds and other nuts.

Fourth, the understanding of their nutritional habits. Despite the impact of food on the brain there are many similarities, but different people are still some differences. Gibson explained that, for example, outgoing personality were more like "a nap after lunch," or "coffee", which allows the brain more clearly. Each person's nutritional habits is also important. Eat less exercise more of the person or people who often do not eat, blood sugar down slightly confused mind would commit
