A major US study revealed that sugary drinks may increase the risk of bowel cancer, as an analysis of more than 95,000 women under the age of 50 indicates a link between excessive consumption and disease.
The Independent said, excessive consumption of sugary drinks may increase the risk of bowel cancer before the age of 50, according to a major study on diet and disease in American nurses.
The researchers analyzed the nutritional and medical records of more than 95,000 women who were tracked from 1991 to 2015 as part of the Second Nurses' Health Study in the United States and looked for evidence linking sugary drinks to early diagnosis of bowel cancer.
The scientists reported that women who drank more than a pint of sugary drinks a day were twice as likely to be diagnosed with bowel cancer over the course of the study as those who drank less than a pint per week.
Given that sugary drinks are already known to be harmful to health by increasing rates of obesity and type 2 diabetes.
Researchers at Washington University in St. Louis said their findings provided another reason not to eat much, and wrote in the journal Gut, “Our findings reinforce the importance of public health in limiting the intake of sugar-sweetened beverages to achieve better health outcomes, but some scientists were not involved.” In the study, they said the results were preliminary because only 109 women who enrolled in the study were diagnosed with early bowel cancer, and of those only 16 reported drinking more than a pint of sugary drinks per day.
They said that eating red meat and processed meat, eating a low-fiber diet, smoking, drinking alcohol and being overweight are all factors that increase the risk of developing the disease, and it may be difficult to fully explain them.
“We cannot be certain if the observed association between sugary drinks and bowel cancer under the age of 50 is a cause and effect,” said Kevin McConaughey, emeritus professor of applied statistics at the Open University.
Bowel cancer is one of the most common types of cancer in the United Kingdom, and while only 5% of cases in men and 7% in women are under the age of 50, the incidence rates in these young people have been steadily increasing over the past two decades.
In 2019, a large French study found evidence that sugary drinks may increase the risk of various types of cancer.
To look at whether consumption of sugary drinks in adolescence could play a role in increasing rates of bowel cancer, the researchers analyzed questionnaires completed by 41,000 women about their drinking habits when they were between the ages of 13 and 18 years old. Diabetes daily, a volume of 250 ml increases the risk of developing bowel cancer before the age of 50 by 32%.
But again, some scientists believe that more studies are needed to confirm the effect, and the analysis is based on only 6 cases of cancer found in this group. "This is too small to draw any strong conclusions," said Dr. Carmen Bernas, a nutritionist at the University of Oxford. .
Duane Mellor, a dietitian at Aston University, added that although limiting the intake of sugary drinks may reduce the risk of bowel cancer, it may have little effect without improving overall lifestyle and diet.
