Antioxidants help to protect cells from damage caused by free radicals. Free radicals are unstable molecules that can damage DNA and other cellular components, which can lead to cancer.
Anthocyanins
Anthocyanins are plant pigments that give blueberries their blue color. They also have antioxidant and anti-inflammatory properties.
Pterostilbene
Pterostilbene is a compound found in blueberries that has been shown to have anti-cancer effects in laboratory studies.
Reducing cell proliferation
Blueberries may help to reduce the growth and division of cancer cells.
Inducing apoptosis
Apoptosis is a process of programmed cell death. Blueberries may help to induce apoptosis in cancer cells, which can lead to their death.
Preventing DNA damage
Blueberries may help to protect DNA from damage caused by free radicals and other carcinogens.
Reducing inflammation
Inflammation can play a role in the development and progression of cancer. Blueberries may help to reduce inflammation throughout the body.
A study published in the journal PLOS One found that blueberry extract reduced the growth and spread of breast cancer cells in mice.
A study published in the journal Cancer Prevention Research found that blueberry consumption was associated with a lower risk of esophageal cancer.
A study published in the journal Cancer Epidemiology, Biomarkers & Prevention found that blueberry consumption was associated with a lower risk of colorectal cancer.
