Next to tomatoes, cabbage, and onions, cucumbers are the fourth most widely cultivated vegetable in the world. Cucumbers are composed of 96% water making them an ideal food for detoxification and hydration. They belong to the same botanical family as melons and squashes.

Disease/ Ailments:

Cardiovascular disease prevention
Cancer prevention

Health benefits:

Antioxidant and anti-inflammatory: In addition to vitamin C, beta-carotene, and manganese, cucumbers contain lasiciresinol, pinoresinol, and secoisolariciresinol—three lignan phytonutrients that scavenge free-radicals, helping to improve antioxidant status, inhibit the activity of pro-inflammatory enzymes like cyclo-oxygenase 2, and prevent overproduction of nitric oxide in situations where it could pose health risks. These antioxidant and anti-inflammatory health benefits lower the risk of developing cancer and cardiovascular disease.

Anti-cancer: Lignan phytonutritents play a role in cancer protection by adhering to the bacteria in the digestive tract and converting into enterolignans. Enterolignans have the ability to bind to estrogen receptors and have both pro-estrogenic and anti-estrogenic effects. This lowers the risk of estrogen-related cancers such as breast, ovary, uterus, and prostate cancer. In addition, a group of compounds known as cucurbitancins present in cucumbers may lead to the development of new anti-cancer drugs. Several different signaling pathways required for cancer cell development and cancer cell survival can be blocked by the activity of cucurbitacins.

Purchasing, storing, & enjoying:

Purchasing: Because cucumbers can be sensitive to heat, you should choose the ones displayed in the refrigerated cases in the market. They should be firm, rounded at their edges and be void of yellow discoloration, puffiness, sunken-water spots, and wrinkles at their tips. Their color should be a bright medium to dark green. Note that thin-skinned cucumbers will generally have fewer seeds than those that are thick-skinned. While cucumbers are not listed as one of the top contaminated vegetables, recent research suggests that conventionally grown cucumbers may be susceptible to heavy metal contamination. Cucumbers are available year-round.

Storing: Cucumbers should be stored in the refrigerator where they will keep for several days. If you do not use the entire cucumber, place in a tightly sealed container to prevent the cucumber from drying out. They should be used within one or two days for maximum quality and should not be left at room temperature for too long, as this will cause them to wilt and become limp.


Many people question whether they should consume the skin and seeds of cucumber. Both are the richest source of nutrients from the cucumber and should not be discarded. However, both conventional and organic cucumbers are waxed so both should be thoroughly washed while gently scrubbing with a bristle brush.
