How does the food you eat affects your thinking ability?
Nutrition provides the body with essential micro and macro elements, contributing to the normal functioning of internal organs. The work of the brain depends on the quality of food you eat, the ratio of proteins, fats, carbohydrates and the calorie content, since it consumes about 50% of the glucose supplied within the food. Lack of nutrients and minerals provokes various ailments, in particular fatigue, distraction, inability to concentrate for a long time, drowsiness. The influence of nutrition on human thinking is of great importance, as are regular sports activities that improve blood circulation, including in the brain.
How does food affect brain function?
The human brain consists of a huge number of neurons coated with the myelin sheath, like all nerve fibres in the body. An interesting fact is that myelin is called a “white matter” because of its colour and consists of about 70% lipids (phospholipids and “good” cholesterol), which can transmit impulses to the brain in isolation. This allows us to make precise coordinated movements or perform several functions at the same time without any difficulties.
The remaining 30% of the myelin sheath consists of protein - the building block of cells, which also transports nutrients to the brain, such as glucose, vitamins, and minerals. Therefore, for the normal functioning of the brain, it is necessary to eat proper balanced meals, and pay particular attention to the ratio of nutrients.
The importance of each element
For the normal functioning of the nervous system and brain activity, your daily diet should contain all three components.
Multifunctional substances, which makes possible the process of renewing cells and the transmission of useful substances to them. The amount of protein in the diet should be about 30% to cover all the costs of the body. You can get them from any meat, vegetables, and dairy products.
The main component of the brain, as well as a source of fat-soluble vitamins and essential fatty acids of the Omega group. They are part of phospholipids and are the building block of the “white matter”. Fats also contain "good" cholesterol, which is involved in the production of vitamin D and a number of steroid hormones (testosterone, oestrogen, cortisol). The amount of unsaturated fats in the daily diet can reach 25%. They are found in sea fish, nuts, various seeds and vegetable oil.
The energy necessary for the normal functioning of all processes in the body. The most valuable source is complex carbohydrates: vegetables, fruits and berries, crops, beans (especially chickpeas, lentils). They slowly increase blood glucose levels, and are also stored in the form of glycogen in the liver to nourish the brain if necessary.
Simple carbohydrates in the form of sugar cause insulin surges, having a negative effect on human thinking. After such a meal, you quickly feel tired and fatigued, it is difficult for you to concentrate. Therefore, chocolate does not improve brain function, contrary to popular belief. On the other hand, a prepared meal such as oat-breakfast or a lunch with chicken and vegetables, will give you energy and strength to perform complex physical and mental tasks.
Do vary your daily food routine to saturate the body with as many nutrients as possible. Do not forget to drink plenty of fluids, because our brain is 80% water, which plays a direct role in the transmission of impulses. And for a better mental activity, you can additionally go to gym, which will have a beneficial effect on the body and overall health!
