Summary

This study looks at how different diets—vegan, vegetarian, and omnivorous—affect heart and metabolic health in adults aged 18 to 65 living in Rosario, Argentina. Researchers will measure things like cholesterol, blood sugar, body fat, and blood pressure. The goal is to understand the health benefits and risks of each diet pattern, but no treatment or diet change is given.
