Omega-3 fatty acids or fish oil have several health benefits. Health experts also recommend high intake of fish oil, saying it has high nutritional value and is good for health.
A new study has claimed that eating more fish can help you in protecting against damage to your brain caused by alcohol abuse.
According to several previous studies, long-term intake of alcohol causes major damages to brain and ups the risk of dementia and memory related diseases.
Omega-3 fatty acids are compounds found in fish. Study authors say these compounds help in preserving one to two years of brain health.
An earlier study says Omega-3 fatty acids helps in increasing brain size. This enlargement of brain in turns protect against severe diseases like Alzheimer’s. The study had found that the people who had higher levels of the omega-3 fatty acids were expected to have larger brain volumes as they grow older.
One of the most significant sign of Alzheimer’s disease is the shrinking brain volume. It is also a sign of ageing, researchers said.
The researchers at the Loyola University Chicago Stritch School of Medicine in Illinois conducted this new study. They carried a meta-analysis and found that drinking alcohol at moderate or social levels may lessen the dementia risk or cognitive impairment during aging.
Social level drinking is defined as a maximum of two drinks per day for men and one drink per day for women.
The researchers explained that alcohol intake in moderate amounts lead to toughening of brain cells. It means the brain cells become more resilient to damage. However, the excessive amounts of alcohol devastate the cells leading to neuroinflammation and cell death.
The researchers found that there was up to 90 percent less neuroinflammation and neuronal death in the brain cells, which were exposed to omega-3 docosahexaenoic acid (DHA) compound in comparison to the cells that had just been exposed to alcohol.
Omega-3 docosahexaenoic acid (DHA) is a compound that is found in fish oil.
Study author Michael A. Collins, PhD, “Fish oil has the potential of helping preserve brain integrity in chronic alcohol abusers. At the very least, it is unlikely that it would hurt them.”
“We don’t want people to think it is okay to take a few fish oil capsules and then continue to go on abusing alcohol,” Collins said further.
The study was published in the journal PLOS ONE.
