Diet And About Your Nervous System

The importance of a healthy diet in the maintenance of the brain and nervous system should not be underestimat. Here we have some drinks and vitamins that can help your body and Diet And About Your Nervous System.

The brain and nervous system are probably the most complex and sensitive physiological structures in the human body.

The importance of a healthy diet in the maintenance of these structures should not be underestimate, DietDoc warns.

However, the complex effect of nutrition on brain function and the health of the central nervous system (CNS) is often a neglected field and most members of the public do not associate the foods they eat with the psychological conditions they develop.

Which nutrients are essential for normal brain and CNS function?
The answer to this question is: “All known nutrients in our diets can influence the function of our brains and CNS.”



Some of the most important nutrients, and how they can affect psychological health, are liste here:


Proteins and amino acids

We also tend to forget that most of the essential chemical substances in the brain and CNS – the so-called neurotransmitters, such as dopamine and serotonin – are produce in our bodies from amino acids. The following amino acids and their related neurotransmitters are vital for a healthy nervous system:

Gamma-amino-butyrate (GABA), glycine, aspartate, glutamate

Tyrosine – dopamine, adrenaline, and noradrenaline

Tryptophan  serotonin

Adenosine, ADP, ATP, and AMP

Arginine – nitric oxide

N-acetyl amino acids and peptides


Protein foods that meet these requirements are meat, fish, eggs, milk and dairy products.

In adults, any condition that affects adequate protein intake (very low energy diets, vegan or macrobiotic diets, alcoholism, anorexia) or increases the requirement for protein when intakes may be inadequate (pregnancy, lactation, periods of growth, illnesses that exhaust protein supplies), can lead to an imbalance in the supply of amino acids to the brain and CNS. This can result in neurological fall-out and damage.



B vitamins

The B-complex vitamins, a large group of water-soluble vitamins, all play a role in healthy nerve and brain function. In this article, the three main B vitamins, namely thiamin, riboflavin, and niacin, are considere.






Pronounced vitamin B1 deficiency causes beriberi, which is characterize by edema, shortness of breath and sensory disturbances with paralysis. Muscle weakness, irritability, loss of memory, convulsions and permanent brain damage may also develop.

Nowadays, outright thiamin deficiency is rare in populations that follow a western diet, but subclinical vitamin B1 deficiencies occur and certain conditions such as alcoholism (Wernicke-Korsakoff syndrome), and epilepsy treated with phenytoin, are known to be associate with a high risk of developing thiamine deficiency. The use of certain diuretics can also lead to higher losses of thiamin with associated deficiency.


Foods that are rich in thiamin include:

Organ meats (liver, kidneys), and pork

Nuts and legumes (dry beans, peas, and lentils)



Niacin (nicotinic acid) is another one of the B-complex vitamins that may be link to neurological damage. Mild niacin deficiency is associate with weakness, tremor, anxiety, depression, and irritability. In severe niacin deficiency, the patient may develop delirium, dementia, and death – the dread three Ds of pellagra, which is the deficiency disease caused by a severe lack of niacin in the diet.


Immediate treatment of serious niacin deficiency is usually done by means of B-complex injections or high doses of niacin supplements.


The human body is capable of manufacturing niacin from the amino acid tryptophan. Thus patients with a niacin deficiency will benefit from adequate intakes of high-quality protein foods (see 1 above), as well as sources of niacin, such as:·

Meat – a good source of niacin and tryptophan


It is interesting to note that pellagra (niacin deficiency), which used to be common among populations that ate highly refined cereals combined with a low protein intake, did not occur in countries like Mexico, where the population was also mainly dependent on maize as their staple food.


The disease was relatively common among the black population of South Africa, which subsisted on sifted, white maize meal.

The reason for this is that the indigenous population of Mexico has always made tortillas by soaking the maize in limewater. The soaking process liberates the tryptophan (an amino acid) in the maize and makes it available for niacin production in the human body



Diets deficient in riboflavin or conditions such as anorexia, malabsorption, chronic alcoholism and biliary atresia (narrowing or blockage of the gall duct leading to jaundice and death in the newborn), can cause riboflavin deficiency. It has also been suggested that there is a critical period during fetal development of the digestive system when a deficiency in the maternal diet may cause permanent damage.


The most important dietary sources of riboflavin are:

Dairy products – milk, yogurt, cheese, maas

Meat, poultry, fish, eggs

Broccoli, spinach, and asparagus

Cereals and bread fortified with vitamin B2

While a riboflavin deficiency is not as directly linke to neurological fallout and damage as thiamin and niacin, the anemia associated with a lack of B2 can have neurological consequences.

In addition, the B-complex vitamins tend to work most efficiently when the intake of all these vitamins are at an optimum level. Treatments for thiamin and niacin deficiency will, therefore, usually also include an adequate supply of riboflavin. These are great things for Diet And About Your Nervous System.
