Near the college entrance examination nutrition experts to recruit "7-1" brain supplement method.

With the college entrance examination approaching, many parents are worried about how to prepare a nutritious diet for their children. Today, we invite nutrition experts to help parents and candidates, scientific and reasonable with preparation meals.
High candidates should pay attention to immunity and brain nutrition
for students who are about to face the college entrance examination, the former head of the Department of Food Nutrition and Safety of China Agricultural University any national proposal, high candidates should pay attention to two aspects, one is immunity, the other is brain nutrition. First, to ensure that basic nutrients, such as enough sugar, can ensure the brain's energy supply, enough protein, vitamins and minerals to maintain the body's immunity, nerve activity consumption and so on. Secondly, you can choose foods containing lecithin such as egg yolks, soy, nuts, etc., and choose foods containing omega-3 fatty acids such as sea fish, especially deep-sea fish, and flaxseed oil.
When asked which ingredients in walnuts are good for brain nutrition, He said walnuts are rich in a variety of nutrients beneficial to the brain, such as oleic acid, which can be extended by the chain, ene to form peanut tyroenyl acid, further converted into prostatin, with dilated blood vessels, reduce platelet aggregation, thereby promoting blood flow, to ensure the brain's blood supply.
" walnuts and other nuts contain a certain amount of alpha-linenic acid, but the content is not high, alpha-linenic acid belongs to the omega-3 fatty acids, can be converted into EPA through extension chain, DHA is necessary for the brain, promote nervous system development, but also blood lipid-lowering effects, as well as the promotion of optic neurodevelopment. An important
beneficial to nerves in nut foods such as
walnuts is lecithin, also known as phosphatidylcholine, which provides choline to the body and forms the neurotransmitter acetylcholine, thus maintaining the function of the nervous system. Lecithin is found in nuts and oil crops, but there is no lecithin in edible oils. Because in the process of oil production, in order to prevent grease precipitation, lecithin was removed, so nuts, soybeans and other oil crops, egg yolks and so on are the main food sources of lecithin. In addition to the formation of neurotransmitters, lecithin also has the role of blood lipid reduction.
He Jiaguo introduced, nut foods, rich in B vitamins, melon seeds, peanuts in the vitamin B1, B2 content is very high, after a series of changes, will help metabolism, but also for physical development. Nuts have a good effect, but also high-energy food, should not be too much to eat, can eat a moderate amount of nuts every day.
Ther brain deficiency" such as "cultivation" to supplement experts to recruit "7-1" brain-replenishing method
said Sun Shuxiao, honorary president of the Dietary Guidance Committee of the China Association for The Elderly Health Care Association, through 13 criteria to determine whether the brain is hungry, and through the "7-1" intake of nutrition.
Sun Shuxiao introduced 13 methods to judge whether the brain is deficnough nutrition:
whether the first staple food is fine rice white noodles, coarse grain intake is less than 2 two;
Second whether you prefer desserts
Third, whether to replace boiled water with tea, coffee, drinks
whether the daily intake of fourth fruits and vegetables is not up to standard
whether the fifth daily intake of meat, milk, eggs, fish, beans


Thith does not like to eat eggs

9th daily intake of food varieties not more than 20 categories;
10th whether fried food as breakfast;
11 never eat pig liver, chicken liver, duck liver, etc.;
12 is vegetarian, do not eat plant protein, nuts, bean products, etc.;
13th daily intake of dark vegetables is not more than half.
Sun Shuxiao said the 13 methods to determine whether the brain is missing nutrition, if eight answers "yes", the brain is lack of nutrition. At the same time, to determine whether the brain is hungry and often feel tired, anxious and depressed, like to doze off, inattentive, memory loss symptoms.
if your brain is hungry? Sun Shuxiao said, the use of "7-plus-one" nutritional supplement method. "7" in "7 plus 1" means protein, carbohydrate, fat, minerals, vitamins, cellulose, and fruit.
Sun Shu-man specifically explained that protein, the most basic substance of mental activity, can improve the central nervous system excitability, eliminate amino acid deficiency caused by dizziness, forgetfulness and other symptoms; Depression, attention deficit, attention deficit and schizophrenia caused by fat deficiency; minerals, protection and stimulate the brain, iron are a beneficial supplement to intellectual development, helping to improve cognitive ability, zinc is the active center of brain cell enzymes, strengthening attention and memory effects; vitamins, which make the brain vibrant, certain vitamins are important for brain development and functioning; cellulose and fruit, the energy of the brain's functioning depends mainly on blood sugar, to maintain blood sugar stability can not be separated from cellulose.
the "7-plus-one" "1" refers to energy, the brain consumes 11 calories per hour of energy, the brain also needs 20% of the total body consumption during rest, energy shortage is less resistance.
between meals, it is recommended to add sugar in moderation to the principle of "a small number of times" to add food. During the meal, you can choose foods with a low and medium glycemic index, which is conducive to maintaining the stability of blood sugar for a long time. A banana, a few cookies, etc. can maintain blood sugar levels stable, to ensure the brain's energy supply.
