What are Phytonutrients?
Phytonutrients are biologically active substances that give plants their odor, color and flavor. Phytonutrients contribute to the plant’s self-defense system by protecting it from pests, viruses, bacteria and excessive sunlight. Research indicates that these phytonutrients may also protect the human body from heart disease and certain cancers. There are hundreds, probably thousands, of phytonutrients in fruits, vegetables, grains and some herbs.
Phytonutrients and Grapes
Grape phytonutrients are well-known antioxidants that can protect cells from free radical damage, and they appear to have additional disease-fighting properties. Grape phytonutrients have been shown to impact key steps in combating heart disease, certain types of cancer and several other age-related diseases.
Resveratrol, a key phytonutrient found mainly in the skins of grapes, has been linked to the prevention of specific types of cancer, as well as the reduction in heart disease. Resveratrol has also been linked to improved brain health and is believed to have the potential to protect against acute and chronic neurological diseases.
Grapes are important sources of flavonoids, including catechins, quercetin, procyanidins and anthocyanins. Grapes also contain the carotenoid lycopene, widely recognized for its disease-fighting capabilities.
Annual Health Research Program
The California Table Grape Commission sponsors research on the health benefits of grapes through its annual health research program. Projects under way include studies on heart disease, cancer, nerve function, the bioavailability of grape components and the antioxidants in grapes. |
