Nanitidine Can Form NDMA in the Stomach

When ranitidine enters the stomach, it can interact with “nitrites.” Nitrites are chemicals often found in spicy or salty foods. Food producers add nitrites to certain foods to prolong shelf life. All the way back in 1981, Dr. Silvio de Flora published a study showing that when ranitidine is introduced to nitrites it can lead to “toxic effects.” Dr. de Flora cautioned that if people take ranitidine, they should eat foods low in nitrites and avoid ranitidine near meal times.
