CSIC study says olive oil compound improves diabetic kidney function
Consuming 55 milliliters per day of functional olive oil enriched with oleanolic acid improves kidney filtration capacity and reduces advanced glycation end products in patients with diabetes, according to a study reported by The Conversation.
- Researchers at the Spanish National Research Council (CSIC) evaluated the effects of oleanolic acid derived from olive plants on diabetic kidney complications.
- Participants consumed 55 milliliters daily of functional olive oil enriched with the compound over a one-year period.
- Results showed improved renal function alongside lower concentrations of advanced glycation end products, though the intervention did not cure diabetes.
The therapeutic evaluation addresses a global chronic condition that affected approximately 589 million adults aged 20 to 79 in 2024, according to figures from the International Diabetes Federation cited by The Conversation. Type 2 diabetes accounts for 95% of these cases, characterized by the body’s progressive inability to properly use insulin to manage blood glucose levels. As researchers Javier Sánchez Perona and Alejandro Matamoros Domínguez explained to The Conversation, the pancreas attempts to compensate for cellular insulin resistance by increasing hormone production, ultimately leading to diminished long-term output.
Renal Stress and Vascular Damage from Hyperglycemia
Persistent high blood sugar damages blood vessels and tissues throughout the body, placing severe filtration demands on the kidneys. The Conversation reported that this continuous overexertion deteriorates the blood vessels at the entrance of the organ. Over time, diminished filtration capability leads to chronic kidney disease, representing one of the most frequent and severe complications associated with diabetes.
To combat this vascular deterioration, investigators from the Spanish National Research Council examined oleanolic acid, a natural molecule found in olive leaves and plants. According to The Conversation, the compound targets multiple disease processes simultaneously, including inflammation, oxidative stress, and glucose metabolism. When glucose remains in the body for extended periods, it transforms into advanced glycation end products. The trial demonstrated that oleanolic acid is particularly effective at neutralizing these harmful molecules.
One-Year Dietary Trial Outcomes
The clinical investigation tracked participants over twelve months of daily supplementation with 55 milliliters of olive oil enriched with oleanolic acid. The Conversation noted that at the conclusion of the study period, subjects exhibited enhanced renal performance alongside measurable reductions in advanced glycation end products. While the dietary intervention did not reverse the underlying diabetes pathology, researchers identified the compound as a viable new therapeutic avenue for protecting renal health.
The work builds on broader scientific efforts to isolate plant-derived compounds capable of mitigating metabolic disease complications.
