Treating cancer from fruits and vegetables?

Cancer is a terrible disease that costs many lives every year. Researchers have now found that oranges, grapes and carrots contain cancer-fighting substances that are very similar to those found in approved anti-cancer drugs.

The latest study by Imperial College London found that oranges, grapes and carrots contain substances that could be helpful in the treatment of cancer. The results of the study were published in the scientific reports published in English.

What effect do flavonoids have on cancer?

The study found that out of more than 7,900 molecules in fruits and vegetables, 110 have the potential to fight tumors. This is due to the similarity of the molecules to compounds used in existing cancer drugs. Fruits and vegetables are rich in antioxidants, so-called flavonoids, which give them their color. Flavonoids can help prevent cancer by suppressing inflammation, controlling cell replication, and even causing tumors to some form of suicide.

Healthy lifestyle prevents cancer

Cancer has a variety of different forms. Above all, cancer is characterized by the fact that cells grow uncontrollably, which often destroys surrounding tissue. Every year, several hundred thousand people in Germany develop various forms of cancer. This affects more men than women. However, past research has shown that 30 to 40 percent of cancers can be prevented by a healthy lifestyle. Eating lots of fruits and vegetables could be particularly beneficial because they are rich in antioxidants to fight cancer, the authors report.

This fruit and vegetable is particularly effective

To find out which fruits and vegetables reduce the risk of cancer most, the researchers inserted 7,962 biologically active molecules into a learning algorithm. The algorithm was set up to recognize the properties of 199 approved cancer drugs. Fruits and vegetables with the most anti-cancer agents were sweet oranges, grapes, carrots, cabbage, coriander and dill.

Tea can protect against cancer

Sweet oranges are particularly rich in the flavonoid dydimin. Dydimin is also found in herbs such as coriander and dill. It has also been found that tea (especially green tea, but also black tea) has strong anti-cancer and medicinal properties. This is probably due to the fact that tea is a rich source of the catechins, terpenoids and tannins molecules. These three compounds exert powerful and complementary anti-cancer effects by reducing DNA damage, suppressing inflammation and causing cancer cells to commit suicide, the authors explain.

More research is needed

Our diet represents the largest changeable aspect of human health. Hopefully, the learning algorithm of the study will one day be adapted to the nutritional needs of other complex diseases such as diabetes, the researchers explain. The prepared list of foods will one day serve as the basis for the future of so-called gastronomic medicine. Personalized food requirements should also be identified for these in order to offer the population nutritious, tailor-made and therapeutically effective foods. Until then, however, a lot of further research is needed to find out how much of this food we should eat and how it should be stored, processed and cooked. (as)
