Whilst no one food can prevent or fight cancer entirely, research shows that some foods have greater anti-cancer properties than others.
It may also surprise you to learn that in the scientific articles of Michael S Donaldson. Nutrition and cancer: A review of the evidence for an anti-cancer diet it was concluded that between 30 and 40% of all cancers can be prevented by lifestyle and diet.
We take a look at five foods that are thought to have cancer-fighting properties:
Leafy dark green vegetables such as Kale contain carotenoids. These can act as antioxidants and boost the body's defences. This in turn can stop free radicals from damaging DNA that can lead to top cancer.
Cruciferous vegetables also contain sulforaphane, a plant compound with anti-cancer properties. Studies have shown that this can inhibit cancer cell growth in colon cancer cells.
Wheatgrass contains a high amount of chlorophyll that helps maintain haemoglobin content in the blood. It is also rich in antioxidants and some studies have shown that it can help reduce cancer cells.
One study concluded that wheatgrass extract decreased the spread of mouth cancer cells by 41%. Another test observed about 65% cell death and diminished leukaemia cells within the first three days of treatment using wheatgrass.
Berries are rich in vitamins, minerals, and dietary fibres and have many antioxidant properties. One study showed that blueberries can prevent the growth of breast cancer tumours in mice and another study showed that anthocyanin a compound in blackberries can lower the markers for colon cancer.
Carrots contain beta-carotene, antioxidant scientists believe may protect cell membranes from toxin damage and slow the growth of cancer cells. Carrots also deliver other vitamins and phytochemicals that might guard against cancers of the mouth, oesophagus, and stomach.
All nuts support a health-promoting diet, but Walnuts are unique in several ways and have been studied more extensively than other nuts regarding cancer prevention.
Emerging research shows potential for walnuts to contribute to a cancer-preventive diet through several compounds possibly working together. Ellagitannins, melatonin and gamma-tocopherol may each work through different paths to reduce oxidative stress, inflammation, and gene expression that can lead to cancer.
