In a new finding, researchers said on an alarming note that high-fat diet adversely affects mental health, potentially leading to depression. Apart from this, such a fat-rich diet is likely to cause brain inflammation, impaired memory, etc, the study reveals.
According to the researchers from the Louisiana State University, fat-rich diet may cause health behavioural changes by changing the mix of bacteria in the gut microbiome. The gut microbiome constitutes complete mixture of bacteria present in the digestive system of humans. By complete mixture, study authors referred to trillions of microorganisms present in the digestive system.
For the study, researchers fed mice with fat-rich diet for several days. After analysing the data, the study authors found that mice who received diet high in fat showed repetitive behaviours, memory impairment, anxiety, increased brain inflammation and permeability in their intestines.
“This paper suggests that high-fat diets impair brain health, in part, by disrupting the symbiotic relationship between humans and the microorganisms that occupy our gastrointestinal tracks,” commented John Krystal, editor of Biological Psychiatry.
Fat rich diet have been long known to be linked with stroke and other cardio diseases, but researchers were astonished to know that fat-rich diet can cause behavioural changes. Although they tried to find any interlink between the same, but the exact mechanism is still unknown. However, previous studies have suggested some relation between bacteria in the gut and some psychological conditions.
When depression has become one of the most common disease in the world, the study has warned people to avoid diet high in fat. Depression is the root of several other diseases. Moreover with mental instability, one cannot enjoy life and give their 100 percent to work. All these directs one’s life to misery.
Moreover, previous studies found that poor sleep in the night might trigger weight gain. Researchers found that people who had poor sleep in the night ate more fat-rich food following day and consumed less carbohydrates. Thus, poor sleep might also lead to depression.
