Researchers at Spain’s Universitat Politecnica de Valenicia studied the effects of lycopene in the body. Lycopene is an antioxidant found in several fruits and tomatoes, hence it is also found in ketchup. Researchers found that lycopene is more potent in the sauce rather than the fruits because it has been cooked down thus facilitation absorption in the body. This is relevant because previous studies have shown that the consumption of tomatoes inhibit cell growth which can help to guard off gastric cancer. Furthermore, increasing levels of healthy bacteria in the gut can decrease the risk of gastric cancer. Another recommendation is to eliminate the use of cigarettes as it can double the risk of gastric cancer. Lastly, lowering the consumption of salt is recommended as it can have negative effects to diets.
