How does an increased amount of belly fat work?
Obesity and obesity can lead to various health problems. Researchers have now found that higher levels of belly fat are associated with reduced cognitive function.
In their current study, scientists at Trinity College Dublin found that higher levels of belly fat were associated with reduced cognitive functions in Irish adults over the age of 60. The doctors published the results of their study in the English-language journal "British Journal of Nutrition".
Data from more than 5,000 participants were evaluated
For the current investigation, the experts analyzed the data of more than 5,000 people. They found that a higher percentage of belly fat was associated with reduced cognitive function. Previous studies had previously shown that people who are overweight did not perform as well in memory and visuospatial ability tests compared to people with normal body weight, the researchers say.
There are a lot of obese people in Ireland
In Ireland, more than half of the population over 50 is classified as obese. Only 16 percent of men and 26 percent of women have a body mass index (BMI) in the normal range, say the doctors. The researchers found that a higher waist to hip ratio was associated with reduced cognitive function.
Do muscles protect cognitive function?
This could be explained by an increased secretion of inflammatory markers by abdominal fat, which has previously been associated with a higher risk of disturbed perception, the researchers explain. The doctors found that a healthy BMI protects cognitive function. BMI is a raw measure of body fat and cannot distinguish between fat-free and fat-free mass (muscles), which makes the researchers suspect that muscle is probably the protective factor.
Excess weight affects brain health
Given the high prevalence of obesity and obesity in the older population and the economic and social burden of cognitive dysfunction, the results of the current study suggest that reducing obesity could offer a cost-effective public health strategy to prevent cognitive decline. "While we've been Knowing for some time that obesity has a negative impact on health, the results of the new study make it clear that obesity and excess weight can affect brain health, ”says study author Conal Cunningham from Trinity College Dublin in a press release. This finding could have a significant impact on public health. (as)
