Protect Your Brain
Cucumbers contain an anti-inflammatory flavonol called fisetin that appears to play an important role in brain health. In addition to improving your memory and protecting your nerve cells from age-related decline,1 fisetin has been found to prevent progressive memory and learning impairments in mice with Alzheimer’s disease
Reduce Your Risk of Cancer
Cucumbers contain polyphenols called lignans (pinoresinol, lariciresinol, and secoisolariciresinol), which may help to lower your risk of breast, uterine, ovarian, and prostate cancers.3 They also contain phytonutrients called cucurbitacins, which also have anti-cancer properties. According to the George Mateljan Foundation
Antioxidant Properties
Cucumbers contain numerous antioxidants, including the well-known vitamin C and beta-carotene. They also contain antioxidant flavonoids, such as quercetin, apigenin, luteolin, and kaempferol,6 which provide additional benefits.
For instance, quercetin is an antioxidant that many believe prevents histamine release—making quercetin-rich foods “natural antihistamines.” Kaempferol, meanwhile, may help fight cancer and lower your risk of chronic diseases including heart disease
Freshen Your Breath
Placing a cucumber slice on the roof of your mouth may help to rid your mouth of odor-causing bacteria. According to the principles of Ayurveda, eating cucumbers may also help to release excess heat in your stomach, which is said to be a primary cause of bad breath.
