In South Korea and Japan, stomach cancer rates are unusually high. Scientists have blamed their diet of fermented foods, including pickles. In 2012, a review of 78 studies found a strong connection between eating pickled foods and stomach cancer. According to the British Journal of Cancer, at least 34 studies have found a link between pickled foods and esophageal cancer. The high salt and acid content in pickles are to blame. However, the World Health Organization has clarified that some countries pickle vegetables differently. Nonfermented, acidified cucumbers pose a risk; slowly fermented pickles don’t.
Banned Artificial Flavors
In 2018, the FDA banned seven artificial flavors. This decision stemmed from a study by the US Department of Health’s study on these flavors. Through two animal tests, the researchers determined that these additives could cause cancer in high amounts. Scientists found the flavors in ice cream, candy, carbonated drinks, gum, and baked goods. Because these flavors have already been banned, there is little need to worry about them nowadays. And despite the FDA’s ruling, they agree that most artificial flavors will not harm people in their recommended doses. If you limit these flavors, you should be safe.
