Effect of Aronia Berry Consumption on Inflammatory Parameters

The study will aim to evaluate the effects of consuming freeze-dried aronia berries as an adjunct to medical treatment in patients with chronic obstructive pulmonary disease (COPD), focusing on anti-inflammatory, respiratory, and biochemical parameters.

It will be conducted at a research hospital in Istanbul, involving 50 participants aged 50-80 diagnosed with COPD. Participants will be randomly assigned to two groups: the aronia group (AG, n=25) and the placebo group (PG, n=25). The AG will receive 30 g of freeze-dried aronia powder daily, while the PG will receive 30 g of placebo powder, both for a duration of 8 weeks. Baseline demographic data will be collected through face-to-face interviews, while biochemical, respiratory, anthropometric, and body composition parameters will be assessed both before and after the intervention. Dietary intake records will also be collected and analyzed.
