Cucumbers belong to the same plant family as squash, pumpkin, and watermelon (the Cucurbitaceae family). Like watermelon, cucumbers are made up of mostly (95 percent) water, which means eating them on a hot summer day can help you stay hydrated.
However, there's reason to eat cucumbers all year long. With vitamin K, B vitamins, copper, potassium, vitamin C, and manganese, cucumbers can help you to avoid nutrient deficiencies that are widespread among those eating a typical American diet.
Plus, cucumbers contain unique polyphenols and other compounds that may help reduce your risk of chronic diseases and much, much more.
9 Reasons to Eat Cucumbers
1. Protect Your Brain
2. 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:4
"Scientists have already determined that several different signaling pathways (for example, the JAK-STAT and MAPK pathways) required for cancer cell development and survival can be blocked by activity of cucurbitacins."
3. Fight Inflammation
Cucumbers may help to "cool" the inflammatory response in your body, and animal studies suggest that cucumber extract helps reduce unwanted inflammation, in part by inhibiting the activity of pro-inflammatory enzymes (including cyclo-oxygenase 2, or COX-2).5
4. 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.
