5. Sugar
Condiments for daily use are also said to be associated with cancer. One of them is sugar. Sugar is a food with a high glycemic index, which indicates the degree of increase in blood sugar levels in the body. It is known that high intake of such foods increases the risk of cancer. For reference, it is suggested that by suppressing sugar intakes, the progression of cancer can be controlled, though this theory has not yet been demonstrated. Because cancer cells require sugar for cell division, ketogenic diets, which extremely limit the consumption of carbohydrates, are theoretically considered effective in treating cancer.

6. Salted meat and fish
Besides sugar, salt should be noted. Salted meat and fish contain a large amount of nitrate and nitrite. This suggests that salted foods damage DNA and cause cell variation. Chinese people and Chinese immigrants, who consume more salted foods, are significantly more likely to suffer from cancer in their nose and throat, the researchers note. In general, salted foods are said to cause stomach cancer.
