Eating fish regularly able to combat Alzheimer’s
Eating fish regularly, especially fatty fish, is able to combat Alzheimer’s
An American study revealed that eating fish regularly reduces brain deterioration and Alzheimer’s disease. The British newspaper Daily Express, quoting a study prepared by the University of South Dakota, reported that eating fish once or twice a week resists cognitive decline.
The study showed that eating fish in moderation enhances brain function because it strengthens its blood flow. She added that fatty fish in particular such as salmon, mackerel and sardines are able to combat Alzheimer’s.
The scientists pointed out that this study confirms that food and diet play an effective role in improving the brain for a longer period of life. They stated that fatty fish is rich in omega-3, which breaks down stray proteins that try to destroy memory and thinking.
Scientists emphasized that this study is also important because it shows the link between low omega-3 levels and lack of blood flow in areas of the brain that are essential for learning, memory, depression and aging. By conducting a survey on 166 volunteers in this study, the link between omega-3 levels and indicators of good mental skills was revealed in 128 areas of the brain, and the best results appeared for those who consumed high amounts of omega-3 in learning and memory areas, which are the first areas affected by aging
the secret between lack of sleep and the ability to focus
American scientists confirmed that a mutation in one of the genes allows some people to regain their activity and get enough rest without the need for long hours of sleep.
Most people need at least six hours of continuous sleep to restore their activity and ability to focus, but US researchers discovered the existence of a “genetic variable” in some people that makes little sleep enough to restore their activity and carry out their daily duties.
According to the study conducted by researchers at the Children’s Hospital in Philadelphia on 100 pairs of twins, and its results were published in the scientific journal “Sleep”, it was found that the twins who carry a copy of this variable gene “BHLHE41” averaged about 5 hours of sleep at night only, i.e. less About an hour ahead of their peers who do not carry this genetic variant.
The researchers confirmed that the twins who had this genetic variant “BHLHE41” missed 40% less in the concentration test, after depriving them of 38 hours of sleep, and they needed only 8 hours to recover full activity after completing the experiment, while their peers who did not carry this variant. Genie to 9.5 hours to recover.
Scientists found that the genetic variant does not give its owner a different quality of sleep, but rather helps regulate the internal biological clock, so that its number decreases to reach a quality of sleep that gives better memory and better recovery of physical and mental activity. According to Prof. Professor “Timothy Morgenthiral,” President of the American Academy of Sleep Medicine, the need for sleep is linked to a biological factor and is not subject to the personal desire of the individual.
