Although there are very aggressive types of cancer that develop rapidly, experts say that more than 90 percent of people could very effectively prevent the worsening of this disease if it is detected over time and changed. the way of life.

We often listen to the advice of nutritionists and experts, who say that it is necessary to change the way we eat in order to have a better and longer life. It is not surprising that doctors advise patients who have been diagnosed with cancer to change the structure of their meals.
These seven foods serve to prevent cancer.
It contains numerous polyphenols – catechins that prevent the work of certain hormones. One of them, EGCG (epigallocatechin gallate-3), is one of the most potent molecules in food that prevents cancer cells from forming new blood vessels.
It is found in large quantities in green tea. Sencha, giokuro, matcha – types of green tea from Japan contain the highest concentration of EGCG, while, for example, black tea does not have a large number of phenols due to fermentation, and oolong tea has suffered. partial fermentation so that the content of polyphenols. it’s half green and black tea.
After two or three cups of green tea, the blood is filled with EGCG, which spreads through the capillaries through the capillaries and settles on the surface of each cell, blocking receptors that require the formation of new blood vessels necessary for tumor growth.
Vegetables and fruits rich in carotenoids
Carrots, sweet potatoes, pumpkin, tomatoes, apricots, beets and all brightly colored fruits and vegetables (orange, red, yellow, purple and green) contain vitamin A and lycopene, which have been shown to inhibit the development of cancer cells. .
Lutein, lycopene, phytoen and cantaxanthin stimulate the formation of new immune cells and increase their ability to attack malignant cells. Researchers have also linked carotene-rich foods to extend the lives of breast cancer patients.
Carotenoids are found in many types of fruits and vegetables. Alpha-carotene is found in carrots and pumpkin, lycopene in red fruits (watermelon, red grapefruit and guava, and especially in cooked tomatoes).
Dark green vegetables, pumpkin and red peppers contain large amounts of lutein and zeaxanthin; cryptoxanthin is found in mangoes, oranges and peaches.
Turmeric and curry
Curcumin root produces a yellow powder which is the main ingredient in yellow curry.
No other food has such a strong anti-inflammatory effect, and the main molecule responsible for this effect is curcumin, which has been shown in the laboratory to prevent the growth of a large number of tumors: colon, liver, stomach, breast, ovary. . . and leukemia.
It also causes the death of cancer cells (the process of cell suicide – apoptosis) and prevents tumor growth by inhibiting angiogenesis. Tumor angiogenesis is the process by which a tumor establishes its own blood so that it can continue to grow.
Blackberries, raspberries, strawberries, blueberries … contain antioxidants, such as vitamins C and E and selenium, which block oxidative processes in the body, as well as citrus fruits and nuts.
Polyphenols that give color and taste to fruits, anthocyanin pigments are responsible for many intense colors blue, black, purple and red berries, other fruits and vegetables, block the growth of tumor cells preventing the formation of new blood vessels that they feed him.
The colors in this fruit are their most powerful weapon, they are antioxidants that successfully fight free radicals. The berries are good for general health.
Ginger root is a powerful anti-inflammatory and antioxidant factor that acts against cancer cells, suppresses the formation of new blood vessels that feed cancer, and ginger tea reduces nausea during chemotherapy or radiation.
The characteristic odor of ginger comes from phenol, which is present in ginger in a concentration of about 500 mg / 100 grams.
The antioxidants gingerol, shogaol and ginger dominate. Shogaol, which is released from cooking, has been shown to have the ability to kill cancer cells while keeping cells healthy. It is important to note that similar studies have not yet been done in humans, but the results of animal experiments are promising.
Organically grown vegetables and grains contain large amounts of selenium, which, however, is depleted by intensive agriculture.
Selenium is a mineral also found in fish, seafood, cashews and offal. And its main property is to stimulate immune cells, especially NK cells, which provides a first line of rapid and efficient defense against various diseases by killing cells infected with cancer, viruses or bacterial pathogens and strengthening antioxidant mechanisms. in the body.
Selenium has been shown to play a greater protective role against cancer in men than in women, and is more important in protecting the cancers of the respiratory, prostate, and gastrointestinal tract.
It works to improve the body’s antioxidant status, strengthen the immune system, reduce damage from heavy metals and carcinogens in the body, and repair DNA damage.
As they facilitate bowel emptying, they also reduce the risk of cancer by shortening the time in which the digestive tract is exposed to carcinogenic substances from food.
Organic yogurt and kefir are good sources of probiotics.
