Deficiency of certain brain chemicals or neurotransmitters occurs when a person suffers from depression. A clinically depressed person has low levels of serotonin and norepinephrine in the brain. According to some studies, wrong diet may be responsible for deficiency of these brain chemicals. Our brain needs certain specific nutrients for the production of the key neurotransmitters. Deficiency of these nutrients in our diet reduces secretion of mood enhancing brain chemicals. Simultaneously intake of certain ingredients might obstruct secretion of the key neurotransmitters, causing depression.
Stay away from monosodium glutamate
Monosodium Glutamate or MSG, the popular food seasoning, is believed to cause depression. MSG contains glutamic acid. This ingredient is capable of lifting our mood instantly by triggering nerve impulses. Unfortunately, by over-activating the brain cells, excess MCG might end killing the brain cells, leading to depression. If you want to prevent depression, stay away from foods that contain monosodium glutamate.
Do you avoid sugar to stay slim? Despite all the propaganda against consumption of sugar, to prevent depression we must consume sugar in moderation. Your brain needs glucose to manufacture serotonin. Glucose helps to carry tryptophan, a protein needed to produce serotonin, to the brain. This is the reason why we experience happiness after having something sweet. Sugar from fruits, in the form or fructose and sucrose, and starch can prevent depression.
Select the right cholesterol
Cholesterol is present in our body in various forms. Sex hormones, such as progesterone, testosterone and estradiol contain cholesterol. Cholesterol stimulates the serotonin receptor function of these hormones. The serotonin receptor activity helps to lift our mood. Lack of cholesterol in our diet, inhibits the function of serotonin receptors causing depression. However, while selecting cholesterol for your diet, rely only on good cholesterol sources, present in fish oil, nuts and whole grains.
Is your diet rich in meat, with hardly any fruits and vegetables? Studies have found that excess protein can cause depression. Too much of protein could inhibit secretion of serotonin. Since the numbers of carriers that carry amino acids to different parts of the body are limited, the competition between tryptophan and other amino acids intensifies. Reduced flow of tryptophan to the brain inhibits production of serotonin, causing depression.
