Nutritional medicine involves using food and specific nutrients to prevent, manage, and treat health conditions. This approach recognizes that diet and nutrition are fundamental to overall health and can be as powerful as pharmaceutical treatments for certain conditions. Nutritional medicine focuses on personalized dietary recommendations based on individual health profiles, including genetic predispositions, lifestyle, and existing medical conditions. For example, dietary changes and supplements can be used to manage chronic diseases such as diabetes, heart disease, and autoimmune disorders. Nutritional interventions may include the use of anti-inflammatory diets, elimination diets for food sensitivities, or targeted supplementation with vitamins, minerals, and phytochemicals. Research in this field continues to grow, emphasizing the role of diet in gene expression (epigenetics) and its potential to reverse or mitigate the progression of various diseases.
