An important study has shown that eating healthy foods reduces the risk of cancer.
Foods high in salt, sugar and fat have resulted in cancer rates 11% higher than those who consume healthier foods, according to research conducted on nearly half a million adults .
The research used the British pioneer food system "traffic light", which allows consumers to know whether foods are healthy or not.
Foods considered unhealthy by the study include cakes, cookies, puddings, lasagna, tomato ketchup, and red and processed meats.
The research used the system of the British Food Standards Agency which indicates whether a food contains saturated fat, saturated fat, sugar or salt with a red, orange or green. Each food has an overall score.
The results showed that people who ate foods with healthier scores were less likely to develop cancer, while people with lower-rated diets had a "higher risk of total cancer".
Researchers at the French Institute of Health and Medical Research have found that reducing your junk food consumption and consuming more complete nutritional cuts could reduce the risk of developing cancer by 11%.
Higher cancer rates were specifically observed in colon cancer, upper gastrointestinal tract and stomach in all subjects.
Men were also more likely to develop lung cancer, while women were more likely to develop breast cancer after menopause.
Principal Researcher Melanie Deschasaux of the French National Institute of Health and Medical Research (INSERM) said that front label traffic lights were "relevant" to public health to help consumers make more food choices. healthy chronic diseases.
The researchers examined self-reported dietary choices of 471,495 adults, including more than 74,000 from the UK to Oxford and Cambridge.
The researchers said participants in Cambridge, as well as in France and Germany, were more likely to make poor food choices.
While those in Oxford, which included more vegetarians and people living in Greece, Italy, Spain and Norway, were more "health conscious".
People living in Denmark and the Netherlands were in the middle of the range.
The researchers said in the research published in PLOS Medicine: "In this large multinational European cohort, those who consumed on average food products of lower nutritional quality were more likely to develop cancer in general".
Professor Tom Sanders, nutrition expert at King's College London, said: "The document refers to diets with high scores of low nutritional quality.
"However, it is important to note that diets with higher scores can not be accurately described as nutritionally inadequate or" junk food "because high quality foods include beef burgers and cheddar .
"Even nutritionally adequate diets (that is, those that meet all nutritional requirements) can increase the risk of cancer, especially if they contain carcinogens or are consumed in excess."
But he said that the 11% increase in cancer among people who consumed unhealthy foods was lower than in a previous study that had revealed an increased risk of cancer of 35% in a similar group.
Professor David Spiegelhalter of the University of Cambridge criticized the study.
He said: "The association reported in this study between the nutritional quality of food consumed and the risk of developing cancer is very low and certainly does not justify the bold conclusions of the authors."
