With reference to the study published in the United States medical journal of Neurology, Omega-3 Fatty Acids in Fish oils are capable of delaying brain aging. They are capable of improving the cells in the brain of the user.
Shrinking the volume of the brain is a symptom of Alzheimer’s infection in addition to normal ageing. The recently published study revealed that women with advanced levels of the omega-3 fatty acids available in the fish oil might also have better brain volumes in old age, as well. It is equal to conserving one to two years of the health of the brain.
Detailed study of Omega-3 Fatty Acids
Fish such as mackerel, trout, salmon and sardines is a high resource of Omega-3 fatty acids. You can get fish oil pills, as well, over the counter from health food shops, pharmacies, or supermarkets.
For the research, the omega-3 fatty acid levels in red blood cells were experimented in 1,111 elder women who were the participants of the Health Initiative Memory Study for women in the United States. After eight years, when the older women attained the age of 78 years, Magnetic resonance imaging scans were taken to gauge the volume of the brain.
Women with the higher omega-3 fatty acid levels had bigger brain volume mass. They had a 2.7 percent bigger volume in the hippocampus part of the brain as well, which plays a significant role in remembrance.
Report by the research head
In accordance with a report by research head Dr James Pottala, of the South Dakota University, these elevated levels of fatty acids can be attained in the course of diet and the exploitation of supplements. Moreover, the outcomes of the study propose that the result on the volume of the brain is the equivalent of postponement of the usual loss of brain cells that go together with ageing by one to two years.
Remarking about the study, the administrator of research and development at the Alzheimer’s humanity, Dr Doug Brown says that it is interesting to observe that consuming more fish could show the way to better brain volume, principally in the hippocampus, which is an area of the brain that comes under assault in dementia. Usually, the shrinkage of the brain in humans can be associated with dementia and superior brain volumes could point to a better capability of dealing with the damages of the condition, but it is yet difficult to describe this conclusion. This study still leaves researchers in the dark regarding what causes consuming fish has on the increase of dementia particularly.
In an earlier study of over 2,000 elder women, it was discovered that a diet that contains high amounts of omega-3 fatty acids might not defend against the ageing of the brain. The researcher of the Alzheimer’s Research in the United Kingdom, Dr Laura Phipps remarks by email that there has been varied proof as to the advantages of omega-3 fish oils on the human brain and whether they may defend against reminiscence turn down and dementia. This study recommends that advanced levels of omega-3 fatty acids in blood cells are associated with the larger size of the brain, but the likely reasons for this relationship require further study. It is known that the brain gets smaller in size in people suffering from dementia, but it is uncertain from the study what result bigger size of the brain would have on reminiscence and thoughts in the volunteers or their long-tenure risk of increasing dementia.
Researchers are of the opinion that the most excellent way to evaluate whether omega-3 could defend against dementia is in the course of medical trials and so far, tests of omega-3 supplementation have not revealed advantages in defending against the cognitive turn down. At present, the research recommends that an unbiased diet, together with customary exercise, keeping up a healthy weight, not smoking, and keeping the levels of cholesterol and blood pressure in check may assist to maintain the human brain healthy, as they get older.
According to the recent studies, researchers concluded that Omega-3 Fatty Acids in fish oils may hinder the loss of brain cells as they age by one or two years.
