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

A nutritional factor is 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 that grandparents from developing countries who regularly eat fish have a risk of dementia (senility) is smaller.

The study was done to the 1500 senior citizens in China, India, and one Latin American country. Those who initially do not ever eat fish, and then started eating fish a few days a week, until finally eat fish every day, the prevalence of dementia was reduced by 19 percent.

Research 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 ate meat.

Since the study was performed using a one-time survey, some experts say these studies do not indicate causality. “In fact, additional evidence can be obtained from future studies that are a 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.

When the fish is to protect the brain from the aging process, experts believe that the benefits derived from saturated fat content is much omega-3 oils found in fish like salmon, mackerel, tuna or Albacore. Laboratory study showed that, omega-3 have a uterus that can prevent dementia, such as protecting nerve cells, reduce inflammation, and helps prevent the formation of amyloid protein which is often found in the brains of patients with Alzheimer’s.

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 have consistently found that respondents from different countries, except India.

Dementia is a severe and progressive intellectual decline that interferes with social function, work and daily activities. The most dominant setbacks encountered is the reduced ability of memory or memory.
