Raspberries are a significant source of ellagic acid, a phenolic compound known to have potent anti-carcinogenic properties and are an excellent source of anthocyanins, the powerful anti-oxidants, which give berries their deep colors. These retard the effects of aging, prevent cancer and may reduce the risk of heart disease.

They are an excellent source of salicylic acid, a compound closely related to aspirin that may inhibit arteriosclerosis (Hardening of the arteries).

Good source of quercetin, a flavonol and anti-oxidant which has anti-carcinogenic properties. It also reduces the release of histamines, which may minimize allergic reactions.
