The compound luteolin, found in coffee, tea, fruits, vegetables, and leafy greens, may slow down visible signs of aging and reduce the risk of disease, according to British therapist Rob Galloway of Sussex University Hospital, as reported by the Daily Mail.
The doctor cited a study by Japanese scientists who found that luteolin supplements slowed the whitening of mice’s fur. Luteolin is a natural antioxidant that helps protect cells from the harmful effects of free radicals—unstable molecules that can cause damage.
Scientists at Nagoya University administered luteolin to mice genetically predisposed to premature graying, both topically (as an ointment) and orally. As a result, the animals’ melanocytes—the pigment cells responsible for hair color—began to function normally.
The scientists also found that luteolin reduces the activity of the p16INK4A gene, a key marker of cellular aging. This gene signals cells to stop dividing and enter a state of rejuvenation. As we age, its activity increases, contributing to biological aging.
Dr. Galloway noted that the mechanisms behind hair graying also contribute to the development of heart disease and cancer. He suggested that regular consumption of luteolin may help maintain overall health. He also pointed out that parsley, broccoli, fruits, vegetables, tea, and coffee are rich sources of this compound.
