You won’t get cancer from enjoying an occasional drink. But drinking heavily every day could raise your chances of six different cancers: esophageal, larynx, mouth and throat, colon and rectum, breast, and liver. According to the Centers for Disease Control, the chemical acetaldehyde damages DNA and prevents it from repairing normally, encouraging cancer cells. The American Cancer Society recommends a limit of two drinks a day for men and one for women. However, a 2019 study published in the journal CANCER noted that even light drinking could influence the risk. Even one serving per day slightly raised the risk in this research.
Over the years, some ingredients in artificial sweeteners have become concerning. According to the National Cancer Institute, animal studies showed that the ingredient saccharin might promote bladder cancer. In 2005, another animal study noted that the ingredient aspartame encouraged leukemia and lymphoma in rats. Other studies could not replicate these results, according to the Cancer Council. Plus, these tests used high amounts of the ingredients–far higher than artificial sweeteners use. Both the FDA and Food Standards Australia and New Zealand claim that artificial sweeteners are safe to eat.
