A healthy diet at age 50 can reduce the risk of dementia

According to a doctoral thesis, healthy diet choices in middle age can help prevent dementia in later years.

Research results show that people with a healthy, reasonable diet at an average age of about 50 have a 90% lower risk of dementia than those with a less healthy diet, This is the conclusion drawn after the 14-year follow-up study. This study is the first study in the world to investigate the relationship, between a healthy early-middle age diet and the risk of developing later dementia.

The researchers evaluated the link between a healthy diet index based on the consumption of many foods. Vegetables, fruits and fruits, fish and unsaturated fats from dairy products and butter are some of the healthiest foods, while sausages, eggs, sugar, soft drinks, marinated fish Salts and saturated fats from dairy products and designated avocados are unhealthy.

Previous studies of diet and dementia mainly focused on the effects of single foods.'But no one diet is based on a single food, and there are many interactions between nutrients, so it would be more reasonable to study the whole diet model. " Ms. Marjo Eskelinen, MSc, who presented the results of a doctoral thesis in neuroscience, said.

Higher saturated fat intake is associated with less cognitive function and increased risk of dementia.

The effect of dietary fats on cognitive ability and dementia risk has been clearly studied separately. Consuming a large amount of saturated fats is associated with less cognitive function and memory and increases the risk of mild cognitive decline over the next 21 years. Scientists have also shown that the higher intake of saturated fat is associated with the risk of dementia for those who carry the Alzheimer's genetic risk factor, the epsilon 4 variant. apolipoprotin E gene (ApoE) . ' Even people with genetic susceptibility may at least delay the onset of dementia by prioritizing the use of vegetable oils, butter and fat oils from fatty fish in the diet'. , Ms. Eskeline said.

In addition, people who drink 3 to 5 cups of coffee a day are at lower risk of dementia than those who drink less or more than the above.
