Key Takeaways
It is frequently claimed that mental exertion can be significantly more exhausting than certain strength exercises. This is difficult to dispute, as the brain is the central control point of our body, and is also responsible for the majority of life processes and changes within our system. However, as with any system, it requires the appropriate fuel to function optimally. Discover which products can help improve the functioning of our nervous system!

A dietary regime for the zinc brain
Zinc is among the basic elements that ought to be included in a dietary regimen, given that it fulfills a multitude of functions within the body. It is worth noting that this micronutrient is responsible for reinforcing cognitive processes and serves as an effective protection against dementia. Furthermore, it forms hyperoxygenic dysmutase alongside manganese and copper. This substance is a primary antioxidant in our body. Sources: chickpeas, seafood, nuts, oysters, pumpkin seeds, whole-grain products, liver, beef.
Healthy diet - the essential element phosphorus
This essential, inorganic element helps form bone tissue and teeth together with calcium. It also takes part in the mineralization process, which increases their strength. Phosphorus also plays a crucial role in the process of nerve impulse conduction. It aids in maintaining the correct acid-base balance and is involved in numerous energy conversions. It can be found in sunflower seeds, camembert and emmental cheese, cottage cheese, buckwheat groats, sardines, smoked salmon, herring, and eggs.
Omega-6 fatty acids: Linoleic acid
Linoleic acid is one of the key components of the omega-6 unsaturated fatty acids group, which are essential for proper body functioning. It participates in energy processes and supports brain function. It influences the regulation of cholesterol levels and aids in preventing the development of nervous system diseases.
Phospholipid referred to as Lecithin
Lecithin is a general term for fatty compounds that belong to the class of phospholipids. These include substances such as ethanolamine, choline, inositol, or serine. It is often recommended as an effective therapy for supporting memory. It is hard not to agree with this assessment. Choline is a critical component for the production of acetylcholine, which is involved in the transmission of nerve signals between neurons. Thanks to this, thinking is faster and more efficient. Mentioned inositol also allows for a reduction in the state of excessive nervousness and stress. Lecithin can be found in products such as beans, wheat sprouts, walnuts and peanuts, rapeseed, soy, liver, and egg yolk.
Magnesium
The significance of magnesium in the body can be discussed for hours. Besides its beneficial effect on the circulatory system (by regulating blood pressure and vascular resistance), it also prevents the formation of clots and aids in the contraction of the heart muscle. This element is extremely important for the functioning of the nervous system. Why? Magnesium is involved in many energy transformations. In addition to its participation in energy production (by catalyzing the combustion of glucose), it is also responsible for its storage. It can be considered as a kind of control unit for the proper functioning of the brain and the entire nervous system. It is found in: white beans, chocolate, cocoa, buckwheat, almonds, wheat bran, pumpkin seeds, pistachios, soy, wheat germ.
Resveratrol and its saline and ester compounds
Rezerwatrol is an exceptionally potent plant antioxidant, often described as a life-prolonging supplement. Thanks to its antioxidant properties, it effectively combats harmful substances that may impact the nervous system. Furthermore, rezerwatrol regulates high blood pressure, which effectively prevents the development of numerous cardiovascular diseases, including strokes. Rezerwatrol naturally occurs in grapes, red wine, pineapples, blueberries, blackcurrants, apricots, and mulberries.
Vitamin B3, alternatively referred to as Nicotinic Acid
It is impossible to deny the indispensability of vitamins for the appropriate functioning of the body. With regard to the nervous system, particular attention should be paid to vitamin B3, also known as Nicotinic Acid or Vitamin PP. It is a compound that is synthesized in the body from tryptophan, a fundamental amino acid in the organism. The precise role of this substance in the nervous system has not yet been fully understood, however, a deficiency of this component in the body results in significantly impaired concentration, a decline in cognitive abilities, fatigue, exhaustion, and even the development of anxiety disorders. It is present in numerous food products such as peas, turkey, sunflower seeds, peanuts, wholegrain products, tuna, and liver.
For the brain - Iron
The previously mentioned element is responsible for the process of creating new erythrocytes. Furthermore, it partakes in the production of hemoglobin, a conglomerate of protein and blood pigment (hem), which is accountable for transporting oxygen from the lungs to tissues, including the nervous system. However, the benefits of iron enrichment do not cease here. Apart from taking an active role in detoxification and combating microorganisms, this element contributes to the natural fortification of the body during mental exertion. It can be found in lean meat, red meat, liver, and egg yolks.
