Anthocyanins are water-soluble vacuolar pigments that may appear red, purple, or blue according to pH. They belong to a parent class of molecules called flavonoids synthesized via the phenylpropanoid pathway. Anthocyanins occur in all tissues of higher plants, including leaves, stems, roots, flowers, and fruits. Anthoxanthins are their clear, white to yellow counterparts occurring in plants. Anthocyanins are derivatives of anthocyanidins which include pendant sugars.
Anthocyanins are powerful antioxidants in vitro. This antioxidant property may be conserved even after the plant which produced the anthocyanin is consumed by another organism, possibly explaining why fruits and vegetables with colorful skins and pulp are considered nutritious. Research continues to be underway as to the potential range of health benefits from anthocyanins.

Regular consumption of anthocyanin-rich strawberries and blueberries may help prevent heart attacks in young women, suggest study findings.
In evaluating the bioactive compounds of Illinois blueberry and blackberry wines, University of Illinois scientists have found compounds that inhibit enzymes responsible for carbohydrate absorption and assimilation. And that could mean a tasty way to help people with diabetes decrease their blood sugar.
The anthocyanin pigments that provide the "blood" color of blood oranges are not produced in significant amounts unless the fruit is exposed to cold conditions during its development or post-harvest. No cold exposure means poor anthocyanin production and the loss of the entire crop. This means that blood oranges can be grown in many areas of the world, but they are most likely to be exposed to the correct temperature conditions in only a few regions, including their major area of production in Sicily.
For the red pigmentation to develop, blood oranges normally require a period of cold as they ripen. The only place to reliably grow them on a commercial scale is in the Sicilian area of Italy around Mount Etna. Here, the combination of sun and cold/sunny days and warm nights provides ideal growing conditions.
Forget the oysters and the champagne this Valentine's Day. If you want to keep your true love's heart beating strong, Susan Ofria, clinical nutrition manager at Gottlieb Memorial Hospital, said the real food of love is dark chocolate and red wine.
