Colorful vegetables

The world cancer research foundation estimates that about 20 percent of cancer diagnoses in the United States are food related, such as malnutrition, obesity, inactivity and excessive alcohol consumption.Adjusting your diet may prevent cancer.
British dietician Rick Hay recently gave his opinion on cancer prevention food and offered 10 kinds of cancer prevention food for your reference.
Foods like green, red, orange, yellow and purple can help the body defend itself.These brightly colored foods help strengthen the body’s immune system and may also help fight cancer cells.
This means that you should eat vegetables of all colors, and a balanced diet is the most important.
Leafy greens and cruciferous vegetables
Leafy greens such as kale and spinach are rich in immune-boosting vitamin C and carotene.Cruciferous vegetables, including broccoli, cauliflower, Brussels sprouts and cabbage, glucosinolates is natural sources and isothiocyanates, these compounds have a protective anti-oxidation and anti-inflammatory effects, can eliminate harmful chemicals and toxins in the body, and suppress chemical induction of lung cancer, liver cancer, esophageal cancer, cancer of the stomach, small bowel cancer, colon cancer and breast cancer.
Cancer research from the British cancer research centre has shown that some cancers are caused by defective repair proteins that prevent damaged DNA from being repaired.Cruciferous vegetables, on the other hand, can help prevent bowel cancer by protecting DNA repair.
Garlic and Onions
Garlic helps regulate blood sugar levels, and lower insulin levels can reduce the risk of cancer.The higher consumption of raw and cooked garlic, the lower the risk of stomach, colorectal and bowel cancer, according to the national cancer institute.At the same time, the trace element selenium contained in garlic has a good effect on the prevention and treatment of gastrointestinal tumors.
As for Onions, a study reported by science daily says red Onions have the greatest impact on colon and breast cancer compared to other Onions.Onions contain selenium and a plant chemical called quercetin, which inhibits carcinogenic activity and prevents cancer cells from growing.People who eat Onions more often have a lower risk of stomach cancer than those who don’t.
Orange fruits and vegetables
Orange and yellow foods contain superantioxidants such as carotenoids, alpha-carotene, isobeta-carotene, lutein, and lycopene, which protect the immune system.
Cancer rates are more than twice as high in people without vitamin A.Carrot contains carotene can change into A large amount of vitamin A, therefore, can effectively prevent the happening of the lung cancer, even for the transformation of the cancer cells have to stop its progression or make its role reversal.
Carrots are rich in folic acid, which is a B vitamin and has anti-cancer effects.The lignin in carrot also has the function of improving the body’s immunity against cancer and killing cancer indirectly.
Red fruits and vegetables
Red fruit contains natural immune function of gallic acid and procyanidins, and vitamin A and vitamin C at the same time, they also have quercetin, zeaxanthin and lutein and many other plant nutrients, can help the body against pathogens, can be said to be the real super food.
Tomatoes are particularly important in fighting prostate cancer. They contain the antioxidant lycopene, which is also found in apricots, guava and watermelon.
The national cancer institute says lycopene may help prevent prostate cancer cells from dividing.Rick Hay suggests using olive oil when cooking tomatoes to reduce the loss of lycopene.
Herbs and spices
Research by cancer research UK has shown that curcumin can kill cancer cells and stop them from growing.Spices, most importantly turmeric, have anti-inflammatory properties and are effective against breast, bowel, stomach and skin cancer, the researchers said.
Turmeric is a natural pigment and our favorite curry is made from turmeric.Rick Hay recommends eating turmeric and black pepper to strengthen your body’s defenses, along with other hot spices such as peppers, mustard and ginger.
Fermented and probiotic foods
Good intestinal function is a key component of health. Sour vegetables, fermented soy beans and miso are all ideal fermented foods.A study reported in the journal science in 2017 showed that the intestinal microbiota had a synergistic effect on tumor immunotherapy.
The elderly can improve the natural immunity of the human body by supplementing probiotics continuously and appropriately.NK cells are important immune factors against tumor and infection in the body. They mainly attack some tumor cells and virus infected cells.Continuous supplementation of lactic acid bacteria and other fermented foods has a significant effect on improving NK cell activity.
Nuts and seeds
Nuts and seeds can provide the digestive system with what is known as the „anti-cancer agent”, namely dietary fiber and axial 3 fatty acids, to help reduce inflammation.
Almonds and walnuts are high in dietary fiber and hazelnuts are high in oleic acid, which can help reduce the risk of colorectal, endometrial and pancreatic cancer.A harvard medical school study found that women who ate a handful of macadamia nuts, such as Brazil nuts, cashews and bighorn, twice a week, had a lower risk of pancreatic cancer.
9. Green tea
Green tea has been proven time and again to be very helpful to health.The study found that drinking more green tea can prevent cardiovascular and cerebrovascular diseases and reduce the risk of cancer.
Tea polyphenols in green tea have antioxidant effects, and green tea polyphenols inhibit thrombosis.Drinking green tea instead of sugary drinks can prevent the cells and tissues from being damaged by oxidation and has anti-inflammatory effects.Green tea contains green tea that increases the activity of detoxifying enzymes in the liver, inhibits tumor spread and reduces the chance of cancer metastasis.
10. Mushrooms
Studies have shown that a diet rich in nickel and selenium, such as mushrooms, can reduce the risk of pancreatic cancer.The researchers found that those with the highest nickel levels and those with the highest selenium levels had a 33 percent and 95 percent lower risk of pancreatic cancer.
Nickel affects the absorption of iron, and selenium plays an important role in the regeneration of the immune system, helping to prevent cell and tissue damage.Nickel-rich foods include mushrooms, asparagus, etc., and regular consumption can prevent pancreatic cancer.
