Selenium minerals have a huge impact on brain function. Nerve cells must have selenium to produce glutathione, one of the most important antioxidants for the brain.
The brains of animals which are fed with a low-selenium nutritional diet produce less glutathione.
The brain which is not having enough Selenium also shows disturbances in the activity of the main neurotransmitters:
Thus, is indicating the possible injury and dysfunction of the brain, according to recent research.
In addition, the concentration of selenium in the blood decreases as we age with around 7% after the age of 60 years and with 24% after the age of 75 years, according to a study.
Insufficiency of selenium disturbs people’s disposition, possibly because of the disruption of neurotransmitter activity.
Researchers at the American Department of Agriculture have submitted a group of young men to either a selenium-rich diet or a low-selenium diet for three and a half months.
Rich nutrition in this mineral has greatly increased the mood of those men. They said they felt more clear at the mind level, well-placed, agreeable, self-mastery, confident, and energetic.
Psychologist James G. Penland, who co-ordinated the study, said that extra selenium produced a better mood for younger people, although they did not show signs of selenium deficiency. In other words, mood may be corrupted by undetected subclinical deficits.
There are many foods rich in selenium, such as cereals, nuts, garlic, meat, fish, and seafood (especially tuna and oysters).
British psychologist David Benton also observed a big improvement in the condition in 50 subjects aged between 14 and 74 years who took a 100 mg Selenium supplement per day for five weeks.
Some received a placebo, while the others received the Selenium supplement. After some standard tests of good moods were performed, it was found that subjects taking Selenium felt better physically and morally, less confused, anxious, tired, depressed, unsure, or hostile.
