Can Polyphenols Delay Diabetic Complications? Pterostilbene as a Translational Model in Retinal Health
At Polyphenols Applications 2026, we are pleased to welcome Dr. Ángel Luis Ortega as a speaker for a lecture exploring the growing potential of polyphenols in diabetic complications and retinal protection.
Dr. Ortega presentation, entitled: Can Polyphenols Delay Diabetic Complications? Pterostilbene as a Translational Model in Retinal Health,
will address an increasingly important question in preventive medicine:
Can natural polyphenols help slow the progression of chronic metabolic complications before irreversible damage occurs?
Dr. Ortega’s recent studies focus on pterostilbene, a natural polyphenol structurally related to resveratrol, and its potential role in protecting retinal tissues against oxidative stress and vascular alterations associated with diabetic retinopathy.
In a recent 2025 study, his group reported that oral pterostilbene administration was associated with reduced retinal damage and improved oxidative stress markers in patients with diabetic retinopathy. His work also builds on earlier experimental studies showing protective effects of pterostilbene on early retinal alterations in diabetic models.
Beyond diabetic retinopathy itself, these studies raise broader strategic questions for the field of polyphenol research:
Can polyphenols become part of future preventive strategies for chronic diseases? Can targeting oxidative stress and microvascular dysfunction help delay age related metabolic complications?
By connecting oxidative stress biology, metabolic disease, retinal health, and translational nutrition, Prof. Ortega’s lecture will bring an important clinical perspective to Polyphenols Applications 2026.
