- Researchers have long been familiar with the presence of unique polyphenols in plants called lignans, and these health-benefiting substances have been studied extensively in cruciferous vegetables (like broccoli or cabbage) and allium vegetables (like onion or garlic). Recent studies, however, have begun to pay more attention to the lignan content of other vegetables, including cucumbers. Cucumbers are now known to contain lariciresinol, pinoresinol, and secoisolariciresinol--three lignans that have a strong history of research in connection with reduced risk of cardiovascular disease as well as several cancer types, including breast, uterine, ovarian, and prostate cancers.
- Fresh extracts from cucumbers have recently been show to have both antioxidant and anti-inflammatory properties. While research in this area must still be considered preliminary--since it's only been conducted on animals in a lab setting--the findings are clear and consistent. Substances in fresh cucumber extracts help scavenge free radicals, help improve antioxidant status, inhibit the activity of pro-inflammatory enzymes like cyclo-oxygenase 2 (COX-2), and prevent overproduction of nitric oxide in situations where it could pose health risks. It's highly likely that cucumber phytonutrients play a key role in providing these antioxidant and anti-inflammatory benefits, supporting health alongside of the conventional antioxidant nutrients--including vitamin C, beta-carotene, and manganeseâ€"of which cucumbers are an important source.
- As a member of the Cucurbitaceae family of plants, cucumbers are a rich source of triterpene phytonutrients called cucurbitacins. Cucurbitacins A, B, C, D and E are all contained in fresh cucumber. They have been the subject of active and ongoing research to determine the extent and nature of their anti-cancer properties. 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. We expect to see human studies that confirm the anti-cancer benefits of cucumbers in the everyday diet.

Cucumbers have not received as much press as other vegetables in terms of health benefits, but this widely-cultivated food provides us with a unique combination of nutrients. At the top of the phytonutrient list for cucumbers are its cucurbitacins, lignans, and flavonoids. These three types of phytonutrients found in cucumbers provide us with valuable antioxidant, anti-inflammatory, and anti-cancer benefits. Specific phytonutrients provided by cucumbers include
