Polyphenols are natural compounds found in many plants, known for their antioxidant properties. They help protect our cells from damage caused by free radicals, which are unstable molecules that can lead to various health issues. Foods rich in polyphenols include fruits like berries, vegetables like broccoli, and beverages like green tea and red wine. These compounds are not only beneficial for our health but also contribute to the vibrant colors and flavors of many foods. Research suggests that a diet high in polyphenols may support heart health, improve brain function, and reduce inflammation, making them an important part of a balanced diet.
