The composition of a diet greatly impacts the risk and management of metabolic syndrome, a cluster of conditions that increase heart disease and diabetes risk. Diets high in saturated fats, sugars, and processed foods can contribute to obesity, high blood pressure, and insulin resistance. Conversely, a diet rich in whole foods, fiber, lean proteins, and healthy fats can support weight management and improve metabolic health. Key nutrients, such as omega-3 fatty acids and antioxidants, may also protect against metabolic disruption, making dietary choices critical for preventing and managing this syndrome.
