Saturated and animal fats ‘may increase bladder cancer risk in men’

Consuming too many saturated and animal fats could increase the risk of bladder cancer in men, according to new research.

A study funded by the World Cancer Research Fund found that while men increased their risk of cancer through unhealthy fats, women who consumed monounsaturated fatty acids and vegetable oils – such as olive oil , coconut oil and sesame oil – lowered their risk of bladder. cancer.

Cholesterol is a fatty substance that is primarily made by the body in the liver.

Eating too much saturated fat in the diet can raise levels of “bad” LDL cholesterol, which increases the risk of heart disease and stroke.

Foods high in saturated fat often come from animals and include fatty cuts of meat, sausages and pies, butter, cheese, chocolate, cookies, cakes and pastries.

In the new study, led by researchers at Maastricht University in the Netherlands, experts looked at data from 11 fat intake studies involving 2,731 cases of bladder cancer and 544,452 cases without cancer. of the bladder.

The novelty of this research is that it provides insight into the role of fats and oils in the development of bladder cancer.

People in the study completed a questionnaire and their fat and oil intake was calculated in grams per day per 1,000 calories.

The results showed that, among women, those who ate the most monounsaturated fatty acids had a 27% reduced risk of bladder cancer compared to those who ate the least. No such effect was seen in men.

In men, those who ate the most bad fats had a 37% increased risk of bladder cancer, but no such effect was seen in women.

Dr Panagiota Mitrou, Director of Research and Innovation at the World Cancer Research Fund, said: “We already know some of the risk factors for bladder cancer, which causes more than 200,000 deaths worldwide. world, including gender, smoking, age and occupation.

“What is new about this research is that it provides insight into the role of fats and oils in the development of bladder cancer. In the future, we may see personalized dietary advice for bladder cancer prevention.

Principal investigator Dr Anke Wesselius said: “How fats and oils affect the development of bladder cancer has not yet been fully explored, although saturated fats play an important role in many many Western diets.

“These results suggest that the quality of fat consumed impacts the likelihood of developing bladder cancer, and men may see benefit from reducing levels of animal fat in their diets.”
