New Research: No Relationship Between Low-Calorie Sweeteners and Cancer

ATLANTA (August 24, 2009) – A new study conducted by Italian researchers and published in the August 2009 issue of Cancer Epidemiology Biomarkers and Prevention reports that there is no relationship between low-calorie sweeteners and cancers of the stomach, pancreas or endometrium. Over 3000 patients ages 22 to 80 were examined over a 13 year period. The researchers concluded, “The results of the present study indicate that the consumption of sweeteners is not associated to the risk of cancer of the stomach, pancreas, and endometrium.”
Further the researchers stated, “In conclusion, the present study adds further evidence on the absence of an association between low-calorie sweetener (including aspartame) consumption and the risk of common neoplams in the Italian population.” This study builds upon the findings from a 2007 Italian study published in the Annals of Oncology which found no relationship between low-calorie sweeteners and oral and pharynx, esophagus, colon, rectum, larynx, breast, ovary, prostate and renal cell carcinomas.
“This study confirms what we have known for years – low-calorie sweeteners are safe, beneficial and in no way related to cancer,” noted Lyn Nabors, president of the Calorie Control Council. “While it is well established that being overweight increases the risk of developing certain types of cancer, low-calorie sweeteners and the products that contain them have been shown to be helpful in weight loss and control,” added Nabors.
According to the American Cancer Society low-calorie sweeteners do not cause cancer. A 2006 epidemiology study from the National Cancer Institute demonstrates that there is no link between low-calorie sweeteners, such as aspartame, and leukemias, lymphomas and brain tumors. The study evaluated over 500,000 men and women between the ages of 50 and 69 over a five-year period. The researchers found that there was no evidence of an increased risk of leukemias, lymphomas and brain tumors among those who use aspartame.
Low-calorie sweeteners are some of the most thoroughly studied food ingredients in the food supply. The safety of low-calorie sweeteners has been reaffirmed time and time again by leading health and regulatory groups worldwide.

un altro studio fatto nel 2007:

A study of more than 16,000 patients has found no link between sweetener intake and the risk of cancer. This supports a previous ruling by the European Food Safety Authority (EFSA).

The safety of artificial sweeteners has been under scrutiny since the 1970s, when animal studies reported links with some forms of cancer. The studies were criticised because very high doses of sweeteners were used. More recent research in rats found that sweetener intakes similar to those consumed by humans could increase the risk of certain types of cancer. These findings were not replicated in studies of humans. After evaluating these and other studies in 2006, EFSA concluded that no further safety reviews of aspartame were needed and that the acceptable daily intake (ADI) of 40 mg/kg body weight should remain.

The new review, published in the Annals of Oncology, looked at the safety of a number of common sweeteners, particularly saccharin and aspartame. Italian case-control studies conducted over a 13-year period were brought together and checked for associations between sweetener consumption and the risk of developing cancer. Patients with various types of cancers formed the ‘test group’, including those with colon, rectal, oral and breast cancers. The ‘control group’ comprised 7000 patients admitted to hospital for reasons other than cancer.

Dietary assessments were used to compare the intake of sweeteners in each group. No significant differences were found. When individual cancers were considered, it was found that women with breast or ovarian cancer tended to consume fewer sweeteners than controls. In the case of laryngeal cancer, a direct relationship was found between risk and total sweetener intake, although the sample size was relatively small.

The authors concluded that consumption of saccharin, aspartame and other sweeteners did not appear to increase the risk of cancer. Average sweetener intake in Italy is lower than in other European countries, and little data were available for individual sweeteners, or the use of ‘Diet’ drinks. Despite these shortcomings, the study nevertheless makes an important contribution to the debate.
