PhotoStudies have shown that eating too much in one sitting can lead to a habit of overeating. The idea is that eating too much shuts down a hormonal pathway that lets your brain know that you’re full. We recently reported on one study that showed that eating foods high in fat content caused inflammation in the brain that contributed to this problem.

However, a new study shows that denouncing all fats may not necessarily be right either. Although the researchers admit that overeating is problematic, they say that consumers should include some “good” fats in their diet.

“These days, great attention is dedicated to the influence of the diet on people’s wellbeing. Although the effects of high fat diet on metabolism have been widely studied, little is known about the effects on the brain,” said professors Marianna Crispino and Maria Pina Mollica from the University of Naples Federico II.

Unsaturated fats

The researchers say that much of the negative news about fatty diets revolves around saturated fats. These are the types of fats that you would find in products like butter, lard, and fried foods. The researchers say that foods with unsaturated fats are actually good for you.

“The difference was very clear and 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.

Some foods that have high levels of unsaturated fats include nuts like almonds, walnuts, hazelnuts, macadamia nuts, and flax seeds. Other foods like avocados, peanut butter, salmon, and sardines also have high levels. If all those options don't seem appealing, try cooking with vegetable oils as an alternative.

The full study has been published in Frontiers in Cellular Neuroscience.
