High Fat Diets Injurious To Young Brains

A new scientific evidence has emerged to show that an excess of fatty foods could affect the brain development of the young, potentially leading to cognitive defects later in life.
These findings are published in the journal ‘Molecular Psychiatry’. Carried out by a team of researchers from ETH Zurich and the University of Zurich, Switzerland, the study looked at the difference in brains of young and adult mice who consumed either normal food or an extremely high-fat diet, which contained excessively high levels of saturated fats, commonly found in fast foods, charcuterie products, butter and coconut oil.
A low-carb diet means you eat fewer carbohydrates and a higher proportion of fat. This is often called a lowcarb, high-fat diet (LCHF). Most importantly, you minimise your intake of sugar and starches.
It was reported that after a period of just four weeks, the study team observed the first signs of cognitive impairment in the young mice fed the highfat diet, which could be seen even before the mice had started to gain weight.
The same changes in the behaviour of mature mice that had been fed a highfat diet over an extended period were not seen, although they suffered from other health problems as their metabolic systems were severely disrupted and they became obese.
However, Urs Meyer, one of the study’s authors, pointed out that, “this does not rule out the possibility that a high-fat diet may also be harmful for the brains of adult mice.”
A person’s age when the fatty foods are consumed is particularly important as high-fat foods tend to have an even stronger negative impact on the maturation of the prefrontal cortex during the period of late childhood to early adulthood.
This part of the brain takes longer to mature than others, leaving it more vulnerable to negative environmental experiences such as stress, infections and trauma, and as seen in the study, possibly a poor diet.
As it is responsible for the executive functions of the human brain including memory, planning, attention, impulse control and social behaviour, if it not functioning correctly or damaged in any way, it can lead to cognitive deficits and personality changes such as a loss of inhibitions, aggressiveness, or childish or compulsive behaviour.
