Bad for the brain: myths and reality

Bad for the brain: myths and reality

Section 1: Neuronutrients and cognitive functions: Fundamentals of the relationship

The functioning of the brain is a complex and multifaceted process that requires the constant receipt of certain nutrients. These nutrients, known as neuronutrients, play a critical role in providing energy, synthesis of neurotransmitters, maintaining the structure of neurons and protecting the brain from damage. The disadvantage of these substances can lead to a deterioration in cognitive functions, such as memory, attention, concentration and speed of information processing.

1.1. Glucose: the main source of energy for the brain

Glucose is the main source of energy for the brain. The brain consumes about 20% of all the energy produced by the body, despite the fact that it is only 2% of the total body weight. Glucose is oxidized in the mitochondria of neurons, producing ATP (adenosine triphosphate), which is the “energy currency” of the cell. Maintaining a stable level of blood glucose is critical of optimal brain function. Hypoglycemia (low blood glucose) can lead to dizziness, confusion of consciousness and even loss of consciousness. Hyperglycemia (a high level of blood glucose), especially chronic, can lead to damage to blood vessels and neurons, increasing the risk of developing neurodegenerative diseases.

1.2. Omega-3 fatty acids: structural component of cell membranes

Omega-3 fatty acids, especially DHA (nonsense) and EPA (eicosapentaenoic acid), are important structural components of cell membranes, including neurons membranes. DHA is about 40% of all fatty acids in the brain. They play an important role in maintaining the fluidity of cell membranes, which is necessary for the effective transmission of signals between neurons. Omega-3 fatty acids also have anti-inflammatory properties that can protect the brain from damage caused by inflammation. The disadvantage of omega-3 fatty acids in the diet can lead to a deterioration in memory, a decrease in attention and an increase in the risk of depression.

1.3. B vitamins B: Copactors of enzymes involved in the metabolism of neurotransmitters

Vitamins of group B, including vitamin B1 (thiamine), vitamin B6 (pyridoxin), vitamin B12 (cobalamin) and folic acid (vitamin B9), play the role of coffee houses for the metabolism of neurotransmitters, such as serotonin, dopamine and norepinephrine. These neurotransmitters play an important role in the regulation of mood, motivation, sleep and cognitive functions. The lack of vitamins of group B can lead to a deterioration in memory, depression, irritability and fatigue.

• TIAMIN (B1): Glucose and production of ATP is necessary for metabolism. The deficit can lead to Vernika-Korsakov syndrome, characterized by confusion, loss of memory and problems with coordination.
• Pyridoxin (B6): Participates in the synthesis of neurotransmitters and hem. Deficiency can lead to depression, anxiety and sleep problems.
• Kobalamin (B12): It is necessary to maintain the myelin membrane of the nerve fibers and the synthesis of DNA. Deficiency can lead to neurological problems, such as peripheral neuropathy, weakness and memory loss.
• Folic acid (B9): It is necessary for the synthesis of DNA and RNA. Deficiency can lead to depression, fatigue and memory problems.

1.4. Kholin: The predecessor of acetylcholine

Kholin is an important nutrient, which is the predecessor of acetylcholine, neurotransmitter, which plays a key role in memory, training and muscle control. Kholin is also a component of phosphatidylcholine, the main phospholipide in cell membranes. The lack of choline can lead to a deterioration in memory, problems with concentration and muscle weakness.

1.5. Magnesium: neural excitability regulator

Magnesium plays an important role in the regulation of neural excitability and transmission of signals between neurons. It blocks NMDA receptors, preventing excessive stimulation of neurons and protecting the brain from damage caused by exaytotoxicity. Magnesium also participates in the synthesis of neurotransmitters and blood pressure regulation. The disadvantage of magnesium can lead to anxiety, irritability, headaches and sleep problems.

1.6. Zinc: antioxidant and immunomodulator

Zinc is an important trace element that plays the role of antioxidant and immunomodulator. It protects the brain from damage caused by free radicals, and supports the immune system, which is important to prevent inflammatory processes in the brain. Zinc is also involved in the synthesis of neurotransmitters and the regulation of appetite. The lack of zinc can lead to a deterioration in memory, depression and a decrease in immunity.

1.7. Iron: component of hemoglobin and enzymes involved in the metabolism of the brain

Iron is an important component of hemoglobin, which transfers oxygen to the brain. Iron also participates in the work of a number of enzymes involved in the metabolism of neurotransmitters and energy. The lack of iron can lead to anemia, fatigue, weakness and deterioration of cognitive functions.

Section 2: Bad for the brain: Classification and estimated effects

Bades for the brain, also known as nootropics or “smart tablets”, are a wide range of substances that are advertised as means to improve cognitive functions, such as memory, attention, concentration, information processing and motivation. These additives can contain various ingredients, including vitamins, minerals, plant extracts, amino acids and synthetic compounds.

2.1. Plant extracts:

• Ginkgo biloba: Improves blood circulation in the brain, potentially improving memory and cognitive functions. The mechanism of action is associated with antioxidant and anti -inflammatory properties, as well as inhibiting platelet aggregation. Evidence of effectiveness is contradictory, and additional studies are needed.
• Ginseng: It has adaptogenic properties, can improve cognitive functions and reduce fatigue. The mechanism of action is associated with the stimulation of the central nervous system and the improvement of energy metabolism. Efficiency also requires further confirmation.
• Bakopa Monica: It is traditionally used in Ayurvedic medicine to improve memory and training. It is assumed that bacosides, active compounds in the bacope, have antioxidant and neuroprotective properties. Studies show potential benefits for improving memory, but larger and highest quality studies are needed.
• Rodiola pink: It has adaptogenic properties, can reduce stress and improve cognitive functions. The mechanism of action is associated with the regulation of the level of cortisol and the improvement of energy metabolism. Studies show potential benefits to reduce fatigue and improve attention, but further research is needed.
