Inflammatory foods, such as processed snacks and high-sugar items, contribute to chronic diseases by triggering an immune response that leads to systemic inflammation. This chronic inflammation is associated with various conditions, including heart disease, diabetes, and arthritis. Consuming a diet rich in anti-inflammatory foods, like fruits, vegetables, and healthy fats, can mitigate these risks. Understanding this relationship helps individuals make informed dietary choices to promote long-term health and decrease their likelihood of developing chronic illnesses.
