Creating more space for flavonoid-rich foods in our plate may help protect us from several types of cancer, including breast, lung, ovarian, colorectal, endometrial, stomach, and upper aerodigestive tract cancer.

The objective of this meta-analysis was to evaluate the correlation between dietary intake of flavonoids and lignans and cancer development risk. Researchers reviewed evidence from relevant studies on the subject. 

Researchers discovered habitual consumption of flavonoid-containing foods decreased an individual's likelihood of receiving a diagnosis of cancer of the lung, stomach, breast, colon, rectum, ovary, endometrium, and upper aerodigestive tract. This study suggests that individuals who want to minimize their risk of different types of cancer should add more foods packed with flavoniods to their diet.
