400-500 calories per day taken in the form of fast food is enough to increase the risk of forgetfulness, lack of orientation or loss of logic.
A recent study says that more than 400-500 calories per day obtained through fast food, such as hamburgers, half a frozen pizza, or canned foods such as chips or various sweets, are enough to add the risk of impaired cognitive abilities leading to forgetfulness, lack of orientation, inability to complete sentences or a thought or loss of logic.
The study, which involved 10,775 men and women in Brazil over an 8-year period, concluded that people who consumed more ready-to-eat or frozen meals were 28% more likely to experience cognitive decline compared to people who did not. who rarely consume these foods.
The study published in the scientific journal "JAMA Neurology" found that the two most affected countries are the United States and Great Britain, where people consume more than 50% of processed foods per day.
Food - only one of the factors
However, experts emphasize that the data are not "cut with a knife". "This study simply proves that there is a link between the consumption of fast food and the loss of cognitive abilities" - says Duane Mellor, a nutritionist at Aston University in the United Kingdom. who did not participate in this study.
"The problem is that it's observational data, so there's no causal evidence." Mellor points out that researchers know enough about the negative impact fast food and canned foods have on people's health. However, he says, it's hard to say whether these foods are more harmful than those with a lot of fat, salt and sugar.
Experts say this study has failed to find other factors that contribute to the loss of cognitive abilities. "It may be more likely that these people who ate a lot of these foods ate less of healthy foods like vegetables, fruits, nuts, seeds and legumes," Mellor said.
Cognitive health is a very complex issue, and the loss of skills can be caused by many factors other than diet, such as lack of physical activity, smoking, alcohol, as well as cardiovascular and metabolic diseases. This study does not include these factors in its analysis. "This makes it impossible to draw such conclusions," says Gunter Kuhnle, professor of nutrition and food science at the University of Reading in the United Kingdom.
Major health problems worldwide
Unhealthy foods are causing major health problems worldwide. Despite the controversy surrounding the latest study, medical experts and nutritionists like Mellor agree that diet and nutrition are two of the major risk factors for human health worldwide. The facts show that obesity is today a more worrying problem than hunger.
Foods high in fat, sugar and salt, processed or not, are responsible for obesity, cardiovascular disease, cancer and increased mortality worldwide.
Another recent report from the Global Panel on Agriculture and Food Systems Nutrition, an independent group of health and nutrition experts, says developing countries, where the sale of processed food is growing rapidly, are particularly at risk. in the coming years.
According to the report, over three billion people do not have access to healthy food and as a result have poor nutrition.
How can we eat healthier?
It's never too late to eat healthy. Studies show that eating patterns such as the Mediterranean diet help reduce the risk of cognitive decline and cardiovascular disease. The Mediterranean diet contains fresh foods, without too much fat, salt and sugar.
"Try to enjoy a simple and varied diet, based on vegetables, nuts, legumes, seeds and whole grains, and eat moderate amounts of dairy products and fresh meat," says Mellor./ DW
