Effective dietary supplements for the brain: scientific approach
Chapter 1: Neuronutrients and cognitive functions: The basis of the relationship
The brain, the most energy -intensive organ of the human body, requires constant and balanced intake of nutrients for optimal functioning. These nutrients, often called neuronutrients, play a key role in maintaining cognitive functions, including memory, attention, training, reasoning and making decisions. The disadvantage of these substances can lead to a deterioration in cognitive abilities, increased fatigue, a decrease in concentration of attention and even the development of neurodegenerative diseases.
1.1. Brain Energy metabolism: glucose and ketones
The brain consumes about 20% of all the energy produced by the body, while the main source of energy is glucose. Glucose enters the brain through a hematoencephalic barrier (GEB), which is a highly selective membrane that protects the brain from harmful substances. Glucose transport in neurons is carried out using special transporters such as Glut1 and Glut3. Disorders in the metabolism of glucose in the brain are associated with the development of Alzheimer’s disease and other neurodegenerative diseases.
The alternative source of energy for the brain is ketones that are formed in the liver during the breakdown of fats. Ketons can penetrate through the GEB and use neurons as fuel, especially in conditions of glucose deficiency, for example, with a ketogenic diet. Some studies show that ketones can have a neuroprotective effect and improve cognitive functions.
1.2. Neurotransmitters: chemical mediators of the brain
Neurotransmitters are chemicals that transmit signals between neurons. Various neurotransmitters play different roles in the regulation of cognitive functions. The most important neurotransmitters affecting cognitive functions include:
- Acetylcholine: It is important for memory, training and attention. Acetylcholine deficiency is associated with the development of Alzheimer’s disease.
- Dofamine: Participates in motivation, remuneration, attention and control of movements. Violations of the dopaminergic system are associated with Parkinson’s disease and attention deficiency and hyperactivity disorder (ADHD).
- Norepinephrine: Regulates mood, attention, vigilance and reaction to stress.
- Serotonin: It affects mood, sleep, appetite and cognitive functions. The low level of serotonin is associated with depression and anxiety.
- Gamma-aminobral acid (GABA): The main brake neurotransmitter in the brain. GABA plays a role in reducing the excitability of neurons and regulation of anxiety.
- Glutamate: The main exciting neurotransmitter in the brain. Glutamat is involved in learning and memory processes.
The synthesis of neurotransmitters depends on the presence of certain amino acids and other predecessors. For example, acetylcholine is synthesized from choline and acetyl-koa, dopamine-from tyrosine, and serotonin-from tryptophan.
1.3. Structural components of the brain: lipids and proteins
The brain consists of about 60% of fat, and most of this fat is represented by polyunsaturated fatty acids (PNS), especially omega-3 fatty acids, such as non-icosaeenic acid (DHGC) and eicopentinal acid (EPK). PNSK is necessary for building cell membranes, maintaining their fluidity and the functioning of neural receptors. The omega-3 deficiency is associated with the deterioration of cognitive functions and an increased risk of developing neurodegenerative diseases.
Proteins also play an important role in the structure and function of the brain. They form enzymes, receptors, conveyors and structural elements of cells. Amino acids, building blocks of proteins are necessary for the synthesis of these proteins and neurotransmitters.
1.4. Antioxidant brain protection: the fight against free radicals
The brain is especially vulnerable to damage to free radicals due to a high level of metabolic activity and a large number of lipids in its composition. Free radicals are unstable molecules that can damage cell structures, including DNA, proteins and lipids. Antioxidants are substances that neutralize free radicals and protect the cells from damage. The most important antioxidants for the brain include vitamin E, vitamin C, glutathione and carotenoids.
Chapter 2: Scientificly based dietary supplements to improve cognitive functions
