Prevent senile with Fish

Along with age, in general there is also decline in organ function and physical changes. The problem that also comes in old age is the decline in cognitive abilities with symptoms of forgetfulness, and if it causes severe dementia.

Nutritional factor turned out to hold an important role in preventing cognitive decline in senior citizens. One food that is recommended for the elderly is the consumption of fish. Research shows, grandparents from developing countries who regularly eat fish have a risk of dementia (senility) is smaller.

The study was conducted on 1,500 seniors in China, India, and one Latin American country. Those who initially do not ever eat fish, then began to eat fish several days a week, until finally eat fish every day, the prevalence of dementia was reduced by 19 percent.

A study published in the American Journal of Clinical Nutrition is not just show a simple relation between fish consumption and dementia. It is known that the elderly who often eat meat have a higher prevalence of dementia than those who never eat meat.

Because the study was conducted using a one-time survey, most experts say these studies do not indicate causality.

"In fact, additional evidence can be obtained from further studies that are follow-up regularly to see the link between fish consumption and reduced risk of dementia," said Dr Emiliano Albanese, from King's College London, UK.

If the fish does protect the brain from the aging process, experts believe that the benefits derived from saturated fat content of omega-3 oils found in many fish, like salmon, mackerel or albacore tuna.

Research in the laboratory showed that omega-3 have content that may prevent dementia, such as protecting nerve cells, reduce inflammation, and helps prevent the formation of amyloid proteins are often found in the brains of Alzheimer patients.

This latest research results obtained from a study of 14,960 elderly aged 65 years and over who live in China, India, Cuba, Dominican Republic, Mexico, Peru, and Venezuela. The relationship between dementia and decline in fish consumption are consistently found in respondents from various countries, except India.
