Reduce risk of some cancers

Walnut consumption may lower your chance of developing several cancers, including breast, prostate, and colorectal cancer, according to test-tube, animal, and human observational studies. Walnuts are high in polyphenol ellagitannins, as was already mentioned. These can be transformed into substances known as urolithins by certain gut microorganisms. Eating walnuts may help prevent colorectal cancer in part because urolithins have anti-inflammatory qualities in your stomach. The anti-inflammatory properties of urolithins may potentially aid in preventing other malignancies.

Additionally, because urolithins resemble hormones, they might block hormone receptors in your body. Your risk of hormone-related malignancies, notably breast and prostate cancer, may be lowered as a result. In order to validate the effects of consuming walnuts on lowering the incidence of this and other cancers and to define all the processes by which they may aid, further human research is required.
