8. Citrus Fruits
Citrus fruits like oranges, lemons, grapefruits and limes have been linked to a lower risk of cancer in certain studies. A greater intake of citrus fruits has been linked to a lower risk of developing cancer in the digestive and upper respiratory tracts, as well as being linked to a reduced risk of pancreatic cancer.
Another review of 14 sudies showed that a high intake of citrus fruits, consisting of at least 3 intakes a week, reduced the risk of stomach cancer by 28 percent. Citrus fruits are also packed with other great nutrients like fibre and vitamins, so taking citrus fruits on the regular is almost never a bad idea.
Turmeric is a spice that’s been praised again and again for its amazing health-promoting properties. It has anti-inflammatory, antioxidant and even cancer-preventing effects.
One test-tube study found that curcumin, the active ingredient in turmeric, helped decrease the spread of colon cancer cells, by targeting a specific enzyme related to cancer growth. Other test-tube studies have found that curcumin can help kill off head and neck cancer cells, as well as slowing the growth of breast, lung and prostate cancer cells.
Flaxseed is high in both fibre and heart-healthy fats and as such can be a great addition to any diet. Moreover, studies have shown that it might even have cancer-fighting effects. One study, for instance, treated 32 women with breast cancer with either a daily flaxseed muffin or a placebo for over a month.
The flaxseed group had decreased levels of specific markers that measure tumor growth as well as an increase in cancer cell death at the end of the study. Another study found that flaxseed reduced the growth and spread of cancer cells in men with prostate cancer. Try adding these seeds into your diet by mixing into smoothies or sprinkling it over cereal and yogurt.
