Reported by LIVESTRONG on Saturday (27/11/2010), here are some essential nutrients to the brain before the exam schools:
Protein
Eggs, nuts, seeds and nuts are the foods rich in protein that the body uses to produce amino acids. Amino acids are precursors (the originator of the formation of a compound) to the neurotransmitter which is a certain brain cells, which help maintain mental acuity and motivation.
Although eggs are generally regarded as a breakfast food, but eggs can also be eaten as a snack anytime during the day. Half a cup of cottage cheese (low-fat cheese) and 1 cup of yogurt can also sharpen the brain before the exam.
Omega-3 fatty acids
Humans have known fish as brain food since more than 2,000 years. Omega-3 oils are very important for development and human survival.
Omega-3 is also the nutrients that are necessary for learning, concentration and memory, because it is very important to provide enough energy for the brain.
Foods that contain lots of omega-3 such as salmon, sardines, walnuts, hazelnuts or cashews. Omega-3 supplements are also available in capsule form.
In addition there are foods that can help improve the performance of the brain, there are also foods that should be avoided, namely:
Simple carbohydrates
Simple carbohydrates can indeed increase your energy quickly, but carbohydrates such as white rice can also stimulate the production of serotonin, a neurotransmitter that calm the brain, and create calmness and relaxation. This is usually quick to make people sleepy, it should be avoided for students who will school exams.
Replace simple carbohydrates with complex carbohydrates like whole wheat bread or boiled potatoes. These carbs will make you feel full longer and increases energy.
Coffee and soft drinks
By the final exam, students also must avoid the consumption of coffee and soft drinks high in sugar. Caffeine in coffee and soft drinks can cause anxiety and interfere with the brain's ability to focus.
