Dietary interventions refer to specific changes made to a person's eating habits to improve health or manage medical conditions. These changes can include increasing the intake of certain foods, reducing unhealthy options, or following specific diets, such as the Mediterranean diet or DASH diet. Such interventions are often used to address issues like obesity, diabetes, and heart disease. They can be guided by healthcare professionals, including dietitians and nutritionists, who tailor recommendations based on individual needs and health goals. The aim is to promote overall well-being and prevent chronic diseases through better nutrition.
