Berry Compound Reduces Aging Effect

I wonder how long it will be before the Pterostilbene begins to be added to foods.
Berry Compound Reduces Aging Effect:

"In a new study, aged laboratory animals that ate a diet rich in the berry and grape compound pterostilbene performed better than those in a group that did not eat the enriched diet, scientists with the Agricultural Research Service (ARS) have reported. Pterostilbene reversed measurable negative effects of aging on brain function and behavioral performance."
