A Finnish study found that the fermentation process involved in making sauerkraut produces several cancer-fighting compounds, including isothiocyanates (or ITCs), indoles, and sulforaphane. To reduce the sodium content, rinse canned or jarred sauerkraut before eating. Better yet, skip the hot dog or sausage—these processed meats are associated with a greater risk of colon cancer. Read up on the 20 states with the highest cancer rates.
Eat fewer smoked and pickled foods
Studies find that smoked and pickled foods contain various carcinogens, so, for examples, choose cucumbers over pickles, fresh salmon over lox. Many of these pickled vegetables are common in Japanese and Korean cuisine; the number of people with gastric cancers is higher in Japan and Korea than in the United States.
Skip drying lamps at the nail salon
Although it’s incredibly low for the average woman, ultraviolet drying lamps at nail salons do carry an increased risk of skin cancer for every use. According to Georgia Regents University, anyone who has received between eight and 208 manicures will have damaged skin cells enough to raise the risk of cancer, though every machine emits different amounts of UVA radiation. For most of the lamps tested, eight to 14 visits over 24 to 42 months will create damaged DNA. Instead, protect your hands by applying sunscreen before your mani, or letting your nails air dry. This is the cancer-detecting exam you should never have after noon.
