Researchers developing purple tomatoes

Oregon State University researchers are fine-tuning a purple tomato, a new blend of colors and nutrients. The skin is as dark as an eggplant. But it doesn't just look cool, it could be better for you.

The novel pigment contains the same phytochemical found in blueberries that is thought to reduce the risk of cancer and heart disease.

Six years in the making, the purple hybrid could hit salad plates in two years.

Genetic origins are not at issue. The purple tomato traces its roots to a wild species in South America, not a petri dish.
