It has been an enduring belief that nutrition plays a significant role in the state of mental health of an individual. But is this true or not?
Recent as well as previous researches have proven that nutrition (or the lack of it) does have effects on how a person’s brain functions, his moods and his behaviors.
Say for example, a person who has skipped a meal is observably weak, out of focus and irritable. This case worsens when extended to a certain period of time when the person becomes severely moody and indifferent to the demands of his environment thus showing decreased speed in reaction time.
These behaviors occur due to the lack of nutrition supply to the brain. The brain requires high energy and nutrient supply. It comprises, in fact, 20% to 30% of all the energy consumption of the body during rest periods. Thus, any change in diet or nutrition level of the body directly reflects in the mental functioning.
Chronic energy deprivation, such as the case of malnourished people, results to the eventual shutting down of the body by decreasing its activities and redirecting all its energy sources towards the systems that require higher energy supply. This results to altered levels of activities, changes in hormonal levels, lessened immune system efficiency and transport of nutrients and oxygen to certain body parts, all of which could directly or indirectly influence mental health. People with extremely low nutrition are more likely to become sad, depressed and emotional as compared with those who have adequate nutrition.
Newborn babies and fetuses are also susceptible to brain damage if they are subjected to lack of necessary nutrition. The type and degree of damage is dependent on the severity of malnutrition. Also, malnutrition among babies has proven to produce low level of intelligence, cognitive defects as well as functional abnormalities.
Protein, carbohydrates, lipids and vitamins all have individual effects on the brain. Lack of supply of these necessary nutrients result to alterations in the activities of the neurotransmitters, a chemical component in the brain that transmit one nerve impulse from one nerve cell to another. Malfunctioning of the transmitt
