Do you want to improve your children's ability to focus? Want them to achieve better grades? With the advent of exam season, you might have tried all kinds of different study techniques and aids to supercharge your kids' study sessions and help them achieve better grades. Yet, by adding some brain foods to your kids' balanced diet, you will have a significant effect on their academic performance. By eating right, your children will be more likely to remain alert, focussed, and energised while they study. Here are some brain foods that will enable your children to pass the exams with better grades: 1. Fish The high concentrations of Omega-3 fatty acids found in most fish are essential to proper neural function. According to several studies reported in the American Journal of Clinical Nutrition, eating fish and other foods high in fatty acids regularly would help us focus more and learn how to study more efficiently. 2. Nuts Like fish, many types of nuts such as almonds, pistachios and walnuts contain high levels of essential fatty acids that help our brain to perform optimally. In addition, nuts contain a good amount of iron, and also provide oxygen to the brain, which increases our mental alertness and ability to retain information. A minimum of one ounce of nuts per day is recommended for optimal brain health. 3. Whole grains Whole grains can lead to enhanced memory function and even better grades. Chow down on whole-grain breads, crackers and pasta while studying for a quick energy boost. 4. Apples An apple a day can help you improve your study habits and academic performance. The peel of the apple includes a powerful antioxidant called quercetin that enhances memory function. 5. Dark chocolate Dark chocolate can improve memory, increase blood flow to the brain, as well as increasing alertness and clarity. The darker the chocolate, the more benefits your brain will receive. 6. Spinach Spinach boosts brain power, and that could mean better grades for your children. Spinach is chock full of folic acid and has even been shown to reverse memory loss. 7. Legumes Beans such as chickpeas, kidney beans and lentils contain substantial amounts of protein, which power the brain and make studying a breeze. In addition, legumes of all varieties contain high concentrations of folic acid, which improves your ability to recall information. 10. Onions Compounds in onions, namely anthocyanin and quercetin, have even been shown to prevent Alzheimer's disease.
