Lycopene in tomatoes can reduce fatty liver, inflammation and liver cancer
In the fight against cancer, there is a surprising tool in the arsenal: the food we eat. This is because some of the nutrients in the food have been found to play a role in the prevention of cancer, and it is of great significance. Because the World Cancer Research Fund reported that 30% to 50% of cancer cases are preventable, the first priority is to prevent cancer.
Xiang-Dong Wang, deputy director and senior scientist of the Human Aging Nutrition Research Center of Tufts University, USA, studies how food can help prevent cancer, especially lung cancer, liver cancer and colon cancer.
Although the incidence of most cancers is declining, people in the United States are increasingly concerned about the increase in the incidence and mortality of liver cancer.This is partly because of the simultaneous increase in non-alcoholic fatty liver disease, obesity and diabetes.
An interesting food is tomatoes (also known as tomatoes) and tomato products that are rich in lycopene. Lycopene is a naturally occurring pigment that makes many fruits and vegetables appear red.
In a new study, Wang and his team investigated the cancer prevention effects of tomato, a food rich in lycopene. At a young age, mice were infected with a type of diethylnitrosamine Liver carcinogens, followed by an unhealthy high-fat diet, which is similar to the Western diet, with or without tomato powder containing lycopene. They then evaluated how well tomato powder protects mice from inflammation And cancer. For humans, this is equivalent to eating two to three tomatoes or one serving of spaghetti with tomato sauce a day.
What did this new study find?
These researchers confirmed for the first time that tomato powder rich in lycopene can effectively reduce fatty liver inflammation and liver cancer produced by the high-fat diet in these mice. Feeding mice tomato powder increased the richness and richness of beneficial bacteria. Diversity and prevent the overgrowth of some bacteria related to inflammation.
Interestingly, they observed that tomato powder is more effective in preventing liver cancer than the same dose of purified lycopene supplements. This may be due to the potential beneficial effects of other nutrients in natural tomatoes, such as vitamin E, vitamin C, folic acid, minerals Phenolic compounds and dietary fiber.
The next step will be to conduct high-quality randomized clinical trials in humans to learn more about the role of lycopene in tomatoes in reducing the risk of inflammation and liver disease. At the same time, these researchers believe that the intake of tomatoes is rich in tomatoes. Natural foods of red pigment may be more effective in preventing cancer than isolated or purified lycopene.
How much do people know about lycopene?
The richest source of lycopene is tomatoes. Other foods, including guava, watermelon, grapefruit, papaya and sweet red peppers, also contain lycopene, but its concentration is much lower than that of tomatoes. Eat tomatoes and tomato products. , Such as tomato sauce rich in lycopene, is associated with a lower risk of cardiovascular disease, osteoporosis, diabetes, and certain cancers (including prostate cancer, lung cancer, breast cancer, and colon cancer).
``Although these correlations come from observational studies, many laboratory studies have shown that lycopene is a powerful antioxidant, anti-inflammatory and anti-cancer agent.
How do people maximize the benefits of lycopene?
Eating natural foods, such as tomatoes and processed tomatoes extracted from canned natural tomato products, ketchup and tomato juice, are the best sources of lycopene. Cooking tomatoes and adding a small amount of fat, such as olive oil, can help increase the absorption of lycopene.
