Mental retardation: 4 foods linked to “deteriorating mental skills”

Dementia is a general term for symptoms associated with decline of the brain – will increase in the coming decades as more and more Britons age. Healthcare systems are preparing for a crisis, but its consequences can be mitigated.

Current research is shedding light on the role that diet plays in brain damage. According to Dr Michelle Luciano from the University of Edinburgh, if you want to keep your brain in good shape, you should limit your intake of saturated fat. Saturated fats, which are usually solid at room temperature, are associated with poor cardiovascular outcomes, and what's bad for the heart is invariably bad for the brain.

Highlighting some of the most dangerous foods, such as butter, palm oil, dairy and meat, Dr. Luciana explained how saturated fat can undermine brain health. Saturated fat intake 'linked to decline in cognitive skills in old age'.

What the evidence says

Researchers found that people with higher levels of saturated fat fats in the blood predispose to the development of dementia, including Alzheimer's disease – the most common type.

A group of scientists led by Dr. Miken Jensen and Dr. Manya Koch, who work at the Harvard School of Public Health. T. H. Chana, looked for 45 different types of fat particles that could circulate in the blood of 1,252 elderly people, 498 of whom developed dementia about five years after the blood was taken.

People with higher levels of saturated fat in the blood are more likely to experience cognitive impairment and develop Alzheimer's disease than people with higher levels of linoleic acid, an omega-6 polyunsaturated fatty acid. contained in many vegetable oils.
