16. Taking too many supplements
Though taking the right dose of daily supplements can prove to be beneficial to your health, a 2015 study from the University of Colorado Cancer Center suggests that consuming more than the daily recommended dose of any supplement could lead to cancer. Specifically, the study discovered that even taking more than the recommended amount of beta carotene supplements increased lung cancer risk by 20 percent.
17. Eating charred meat
When people eat meat, they tend to like it charred. The issue with this, however, is that cooking meat at high temps can form chemicals that cause changes in the DNA—changes that can increase your risk of cancer, says the National Cancer Institute. If you do cook meat, make sure it’s not getting over-done.
Or, even better, ditch the animal product altogether: A 12-year study published in the journal Nature in 2009 found that the incidence of cancer was much lower with vegetarians compared to meat-eaters.
18. Eating processed meat
Veggie dogs might be the only safe summer BBQ option when it comes to preventing cancer. In 2015, the International Agency for Research on Cancer officially classified processed meat as a carcinogen, noting that eating just 1.8 ounces a day can increase your risk of colorectal cancer by 18 percent.
19. Drinking too much
Having a drink here and there is totally fine, but when you’re having more than one or two drinks per day, that’s when problems arise. According to the American Cancer Society, overdrinking has been linked to a higher risk of throat, liver, colon, and breast cancer. So when you’re out, make sure to pace and limit yourself.
20. Making microwave popcorn
Sure, it’s quick, easy, and delicious, but microwave popcorn is also dangerous. The snack contains the chemical diacetyl in its butter flavoring, which can actually lead to lung issues, according to a 2013 study published in the PLOS One journal. Diacetyl is also one of the chemicals in e-cigarettes that has been causing concern as they pertain to cancer.
