Diet and Cancer Link - No Single Food Causes Cancers Says Registered Dietitian
Although it has been estimated that 20 to 30 per cent of all cancers may be related to diet, there is no evidence that any single food causes cancer. In fact, what you are NOT eating, may be more important than what you are eating says a registered dietitian who has provided extensive nutrition consulting services in the area of diet and cancer. “Diets are so complex that before we come to conclusions there needs to be many types of studies yielding duplicate results.”

In a recent fact sheet, published by the Beef Information Centre, Laura Pasut, president of Nutridata Consulting Service concluded that there is no scientific evidence red meat causes cancer. “When you look at a large number of population studies it becomes apparent that a low intake of vegetables, fruits or grains, a lack of exercise or obesity may be far more important than the level of meat consumption,” she said.

According to Ms. Pasut, beef is an important part of a balanced diet, providing 12 essential nutrients, including readily-available iron, zinc, protein and B vitamins. If people are misled and avoid certain foods because of concerns about cancer, there is a much greater risk of a nutrient deficiency.

Ms. Pasut says it’s also important to take into consideration protective factors. Beef contains a particular fat, CLA (conjugated linoleic acid). Recent research at the University of Alberta indicates CLA, found primarily in beef and milk fat, may help prevent breast cancer.
