Separate studies in the United States and Italy have shown that people who eat fast food or undernourished foods are more likely to have colorectal cancer and heart disease.
Marion Nestle, professor of nutrition, food studies and public health at New York University, said, "There have certainly been hundreds of studies on fast food or undernourished food, and all of them have shown that eating fast food is more likely to cause cancer, heart disease. ’
He added that this research is a continuation of all the research done in the past, fast food or low-food items clearly increase the chances of infectious diseases.
The us study looked at more than 200,000 men and women over the age of 28, most of whom found a link between fast food and colorectal cancer in men, making colorectal cancer the third most commonly diagnosed cancer in the United States.
Feng Fang Zhang, a cancer epidemiologist at Tufts University's Friedman School of Nutrition Science and Policy in Boston, said, "Research has shown that men use fast food more than women, and men are 29 percent more likely to have colorectal cancer than women."
Why was the risk of colorectal cancer not found in women?
Fengfang Zhang said, "The tendency of obesity in women compared to men, the role of metabolic hormone is different than men, perhaps that is why women are less likely to get this cancer than men."
"Women may be eating a healthier diet than men," said Dr. Robin Mendelson, a gastroenterologist at the Memorial Sloan Kettering Cancer Center in New York City, who was not involved in the study.
Another study was conducted in Molis, Italy, where more than 200,000 people were evaluated, this study was started in 2005, in which the possibility of epidemic diseases in cancer, heart and brain was cited.
According to comments published in the British Medical Journal, items that are high in sugar and on the other hand, are more likely to die due to chronic diseases or early death due to low-nutrient items, research has shown that eating both types of food increases the chances of cardiovascular disease and early death.
"Even 80 per cent of diet based on nutrition has been rated unsatisfactory," said Marialora Bonacio, an epidemiologist in Italy.
"This suggests that the chances of dying early are not from undernourished items, but from eating more fast food or foods that are high in calories," he said.
