"Cholesterol-lowering Potential of Sunflower Seeds: Evidence From Phytochemical and Fatty Acid Composition and a Randomized Human Trial"

This randomized, open-label human trial evaluated the cholesterol-lowering potential of sunflower seeds in adult participants. Eligible men and women were recruited based on inclusion criteria, which included age range, baseline cholesterol levels, and absence of major health conditions. Participants were randomly assigned to consume a defined daily portion of sunflower seeds for a specified intervention period. Blood samples were collected at baseline and at the end of the intervention to measure total cholesterol, LDL-C, HDL-C, triglycerides, and other relevant lipid parameters.

Prior to the human intervention, sunflower seeds were analyzed for their nutritional composition, mineral content, phytochemical profile, and fatty acid composition using standard laboratory procedures. Tests included proximate analysis (moisture, protein, fat, ash, and carbohydrate content), mineral quantification (calcium, magnesium, potassium, etc.), phytochemical assays (total phenolics, flavonoids), and fatty acid profiling using gas chromatography. These analyses provided a detailed characterization of the seeds' bioactive components relevant to cardiovascular health.

The study also included assessments of dietary intake, anthropometric measurements, and adherence to the intervention. The primary objective was to determine the effect of sunflower seed consumption on blood cholesterol levels, while secondary objectives included evaluating changes in lipid profile and potential associations with bioactive components of the seeds. Data were analyzed using standard statistical methods. The results aim to provide evidence on the role of sunflower seeds in cardiovascular risk management and to inform dietary recommendations.
