The brain is one of the most complex organs of the human body. Neither mental work nor normal physiology is possible without it. Its functioning requires a variety of amino acids, polyunsaturated fats, Omega 3 and Omega 6, vitamins (especially vitamins E and C), water, and many other substances and compounds.
The most beneficial foods for the brain
Sea fish and seafood

Sea fish and seafood are a must-have dietary components to improve brain function and the entire nervous system. Phosphorus, iodine, minerals, and Omega-3 fatty acids help the brain stay functional and youthful. They affect the reduction of “harmful” cholesterol, the cleansing of the walls of blood vessels of fatty plaques, the active saturation of the brain cells with oxygen and nutrients. By the way, if you have high cholesterol, you can start taking lipostat.
Eggs.
The yolk of the egg contains choline, which nourishes the cells and neurons of the brain, without which they will not be able to form and exist. Eating 1-2 eggs a day is enough to eat eggs regularly.
Milk.

Milk is essential to the brain because it contains tryptophan, a substance that is the source for the synthesis of serotonin, the hormone of joy. In addition, the antioxidant glutathione, which researchers in milk recently discovered, improves neuronal function and allows you to keep your sanity until your old age.
Grains.
Oats, wheat, barley, unpeeled rice, and bran contain a lot of folic acid and thiamine, i.e., vitamin B6. Thus, cereals and whole-grain bread are useful to improve metabolism and as a great stimulant of blood circulation and improve brain activity.
Nuts.
Seeds and nuts are used both as an independent snack and an additional ingredient in dishes. They contain everything the brain cells need: vitamins E and B, folic acid, omega-3, omega-6 fatty acids, and minerals, including magnesium and potassium. Nuts such as almonds, walnuts, cashews, peanuts, hazelnuts, pecans, and all kinds of seeds nourish the brain, give much energy, improve memory, elevate mood and even lessen the signs of depression.
Green and leafy vegetables, greens.
Greens contain so many important vitamins for a mental activity that even a single shock can: remember or recall a lot of valuable information, raise the productivity of thought activity, and relieve fatigue. These results are due to many B vitamins and folic acid.
Berries.

Vitamins, sugars, fiber, antioxidants, and flavonoids from berries help in case of great mental stress, improve coordination and memory, preserve youth and increase the efficiency of cells.
Dried fruits.
The rich vitamin and mineral composition makes dried fruit a product of prime necessity for those who want their head to work fast and well. Dried apricots, raisins, prunes, figs, dates, and other dried fruits and berries reduce the level of “bad” cholesterol in the blood, clean the brain vessels from cholesterol plaques, improve memory and concentration and help maintain good coordination.
Honey.
Honey is a recognized healer of the cardiovascular and nervous systems. The diet must clean the blood and blood vessels of “harmful” cholesterol and improve cerebral circulation with constant mental work.
Tea.
Both black and green teas contain catechins. These unique substances help improve brain activity, remember information well, relax, and recover faster. Tea is best consumed in the morning and afternoon.
Curcuma.
Curcuma for the brain is useful because it can relieve inflammation in the brain tissue, restore neurons, destroy sodium benzoate, interfere with connections between brain cells, act as an antioxidant that protects cells from aging, and give a positive mood by producing the hormones dopamine and serotonin.
Ginger.
Spice with a sharp taste and fresh aroma is useful for the heart, blood vessels, and brain cells. Ginger is used as a blood thinner, improves cerebral circulation, with regular use noticeably improves memory, and prevents the development of Alzheimer’s and Parkinson’s diseases.
Lemon.
The value of lemon for the brain is due primarily to its high vitamin C, potassium, magnesium, and other minerals. Lemon helps clean blood vessels from cholesterol buildup, prevent overwork and relieve stress.
Regular water.
The brain cannot work properly without enough fluid in the body. Often a feeling of chronic fatigue and sleepiness are signs of a lack of moisture in the body. The best way to replenish fluids and thus protect your brain from dehydration is to drink plain drinking water: it is best absorbed without additional calories, like fruit juice.
