Cases of cancer directly caused by heredity (genes) are in the minority, some sources speak of 10 to 15%. The vast majority are related to lifestyle and environment. Diet plays a fundamental role and can prevent cancer or, on the contrary, promote it.
The foods mentioned below all have a preventive action against the onset of cancer:
According to various studies, broccoli is recommended in the preventive treatment of cancer due to the presence of antioxidants which act against the development of carcinogenic free radicals. Thanks to sulforaphane in particular, broccoli protects against cancer. Studies have proven that eating broccoli regularly helps reduce the risk of ovarian, lung, kidney, bladder and prostate cancer. You should know that two antioxidant molecules found in broccoli, lutein and zeaxanthin, retain their effects better after short rather than long cooking.
Eating broccoli also helps to lose weight, obesity being a risk factor for cancer. This vegetable is low in energy, there are only 34 kcal in 100 g of edible part.
Chamomile tea would have an effect against cancer. This plant contains a molecule, apigenin, which could prevent the progression of cancer cells according to a study published in May 2013. In work carried out on mice, scientists observed that apigenin could reduce the lifespan of cells cancer cells in the case of breast cancer, which blocks tumor spread. In addition, this substance increases sensitivity to cancer treatments. Apigenin, sometimes called apigenol, belongs to flavones, a subclass of flavonoids. It is advisable to drink a cup of chamomile tea every night, in addition to the probable anti-tumor effect, this infusion will allow you to sleep well and treat certain digestive disorders.
This fruit is excellent for your health, as the saying “an apple a day keeps the doctors away” reminds us. In addition to having a preventive effect on the cardiovascular system (stroke in particular) as shown by a British study from 2013, the apple can have a preventive effect on cancer. It is especially pectin, a soluble dietary fiber found in apples, which provides properties in the fight against cancer.
Its effect is particularly effective in the prevention of colorectal cancer. Fiber promotes intestinal transit and has a regulating effect.
The apple is also rich in quercetin, a molecule of the flavonoid family, with an antioxidant effect to fight against tumor cells.
Quercetin is found in other fruits such as strawberries, blackberries or raspberries.
It is highly recommended to eat one apple a day.
Coffee consumption has a preventive effect on certain cancers, such as cancer of the liver, the colon (would reduce the risk by 25%) and the cervix. A Japanese study published in 2008 showed that women who drank a lot of coffee seemed to have a lower risk of developing cervical cancer. In detail, women who drank more than three cups of coffee a day had a 60% lower risk of developing cervical cancer than those who drank less than two cups a week. A lowering of the insulin level following a regular consumption of coffee would be an explanation for the reduction in the risk of cancer of the uterus.
This is another drink with partly identical properties to coffee. Green tea helps prevent prostate cancer. Indeed, consuming 5 to 6 cups of green tea a day would reduce the risk of developing this common form of cancer in men by half.
Garlic contains allicin, a molecule with antioxidant effects that have a preventive effect on cancer. According to a Chinese study, consuming garlic every day reduces the risk of lung cancer by 44%. Among smokers, this risk was reduced by 30%. The study involved 6,000 people and was carried out by the Center for Control and Prevention of Jiangsu Province, China. Garlic would also have preventive effects on other forms of cancer such as colon and stomach cancer.
For an effect on health, it is advisable to eat a clove of garlic every day, if possible raw garlic (eg in salads) or if cooked, do not exceed a cooking temperature of more than 60 °C, to avoid a loss of its properties. If garlic is eaten raw, it is recommended to cut it finely and then wait 5 to 10 minutes before consumption, because during this period the maximum release of allicin is observed.
Consuming a significant amount of fresh or cooked (cooked) tomatoes seems to have a preventive effect on prostate cancer. Lycopene, found in tomatoes, is the basis of this probable effect against cancer. In addition, an American study has shown that a diet rich in tomatoes could reduce the risk of breast cancer in post-menopausal women at risk.
Consuming tomatoes regularly is not difficult, it is enough for example to add them in a salad or in a sauce.
The cocoa found in quantity in dark chocolate contains a lot of flavonoids. Dark chocolate contains in particular catechins, a powerful antioxidant, antiallergic and anti-inflammatory. Studies have shown that regular consumption of dark chocolate reduces the occurrence of certain heart diseases and may have a preventive effect on cancer.
It is advisable to consume a few squares of dark chocolate every day, for example with coffee.
Grapes also contain a lot of flavonoids and in particular resveratrol, a famous polyphenol found, for example, in red wine and grape juice. It is credited with many qualities such as the prevention of cellular aging, against diabetes or to prevent cancer. However, it should be noted that there are contradictory studies with resveratrol, some scientists believe that the positive effects of this substance for health have been exaggerated, in particular its supposed benefits at the cardiovascular level.

It is advisable to drink grape juice (200 ml) every day, a glass of red wine can also have a preventive effect on cancer. Beware, however, of alcohol abuse, a carcinogenic factor.
In addition: We can mention other foods with a proven effect, or partially, against cancer such as: walnuts, olive oil, turmeric, etc.
