Fried food or fat intake causes inflammation that impedes brain to control hunger and in turn fueling obesity, said a new study.
The main problem for people is to control how much they eat, when to stop and what type of food to eat, which turn to obesity, said researchers from University of Naples Federico II in Italy.
The study conducted on rats found that food with high saturated fat reduces the cognitive function in brain that fails to control how much one eats. These fatty foods affect the brain part called the hypothalamus, which helps regulate hunger.
“Although the effects of high fat diet on metabolism have been widely studied, little is known about the effects on the brain,” said Maria Pina Mollica and Marianna Crispino from University of Naples.
There are different types of fats and saturated fats are found in lard, butter or in fried food, while unsaturated fats are found fish, avocado or olive oil. If one replaces lard with olive oil, it makes a significant difference, says the study.
“We were amazed to establish the impact of a fatty diet onto the brain. Our results suggest that being more aware about the type of fat consumed with the diet may reduce the risk of obesity and prevent several metabolic diseases,” said Crispino.
The findings were published in the journal Frontiers In Cellular Neuroscience.
