Experts have claimed that the essential nutrients found in foods such as broccoli, milk and peanuts, can reduce the risk of bowel cancer.
The researchers said foods high in folate, magnesium and dairy products could all help ward off the second most dangerous type of cancer.
And a new study, published in the journal Gut, found that following a diet with specific nutrients can help protect against the deadly disease – but added that there is no evidence that tea, coffee, fish, onions or garlic will keep cancer at bay.
The researchers looked at cancer data and reviews, as well as clinical and observational studies that assessed the impact of diet and medical factors when it came to developing bowel cancer.
Medicinal agents included: aspirin, and non-steroidal anti-inflammatory drugs (NSAIDs), such as paracetamol; Statins. While considering dietary factors including vitamins or supplements (magnesium, calcium, folate, carotene and selenium); Coffee, tea, fish and omega-3 fatty acids; As well as basic dairy products, fruits and vegetables, meat and alcohol.
The researchers analyzed data from September 1980 to June 2019.
They found that aspirin may prevent bowel cancer, reducing the risk by 14% – with people taking doses as low as 75 mg per day.
Magnesium, which can be found in foods such as nuts, seeds and spinach, is associated with a 23% lower risk of infection, with people consuming at least 255 mg per day.
A high intake of folic acid, found in foods like broccoli, beans and breakfast cereals, was also associated with a 12-15% lower risk – but experts were unable to say what dose would be helpful.
Experts also found that eating dairy products, such as cheese, milk and yogurt, was associated with a 13 to 19% lower risk of developing the disease.
The researchers cautioned that they were unable to draw conclusions about the dose from the analysis.
They found that eating fiber was associated with a 22 to 43% lower risk, while eating fruits and vegetables was associated with a 52% lower risk.
They added that there is a benefit for every additional 100 grams a person consumes per day.
For those who follow a vegetarian diet, soy was also associated with a slight decrease in risk, with a decrease of 8 to 15%.
The researchers stated that there was no evidence that the vitamins, E or C, or multivitamins, were protective.
The data were also weak when it came to the protective properties of the tea; Garlic or onion and vitamin D either alone or with calcium; Coffee and caffeine.
And while observational studies have found that a high intake of calcium may be beneficial, clinical trials have found that this may put you at an increased risk.
Eating meat increased the risk from 12 to 21% – particularly for processed meats and red meat.
Those who consumed 100 mg of these products per day increased their risk of developing bowel cancer by 10-30%.
The researchers explained that higher levels of alcohol intake also increase the risk.
They revealed that the evidence is low in many cases, as they were unable to determine “the optimum dose and duration of exposure / intake for any of the products, even in the case of low-dose aspirin and other compounds.”
The study was published in the British Medical Journal, and experts indicated that the results could help doctors in providing advice to patients on the best diets to reduce the risk of bowel cancer.
