You knew cucumber was good for you, and I recommend cucumber juice while fasting, but it is better for us than we thought.
The bitter flavor in the skins of cucumber, pumpkin, melon, watermelon and squash, are compounds called cucurbitacins. These foods all belong to the wild cucurbits family, and they are all highly beneficial to human health.
Cucurbitacins are now seen as powerful compounds that switch on anti-cancer genes in the body.
