Therapeutic Nutrition and Its Importance in Supporting the Immune System Therapeutic nutrition is considered a fundamental element in maintaining overall health and enhancing the body's ability to resist diseases. It is not just a way of eating, but a science that studies the relationship between food and human health, and how certain foods can improve body functions and support the immune system. The immune system is the body’s first line of defense against viruses, bacteria, and various infections. When the immune system is strong, the body can resist illnesses more effectively. However, a weakened immune system increases the risk of infections and chronic diseases. This is where therapeutic nutrition plays a crucial role in supporting and strengthening this vital system. Vitamins and minerals play a key role in boosting immunity. For example, Vitamin C, found in citrus fruits, vegetables, and fruits, helps increase the production of white blood cells that fight infections. Vitamin D also contributes to activating the body’s immune response and can be obtained from sunlight exposure and certain foods like fatty fish. Proteins are essential in therapeutic nutrition, as they are used to build and repair tissues and produce antibodies that fight pathogens. It is important to consume protein from varied sources such as white meat, fish, eggs, and legumes. Dietary fiber supports the digestive system, which is a part of the immune system. Healthy intestines help produce strong immune cells and reduce inflammation. Therefore, consuming whole grains, vegetables, and fiber-rich fruits is essential. Antioxidants found in fruits, vegetables, and nuts help protect immune cells from damage caused by free radicals, enhancing the body’s ability to resist diseases. Additionally, adequate water intake is important, as proper hydration helps transport nutrients in the body and eliminate toxins, which is vital for maintaining a healthy immune system. Finally, therapeutic nutrition is not just about following a specific diet. It is a comprehensive lifestyle that includes consuming nutrient-rich foods, avoiding processed foods and saturated fats, and engaging in regular physical activity. Through proper therapeutic nutrition, immunity can be strengthened, diseases prevented, and overall quality of life improved.| AL_mustaqbal University is the first university in Iraq.
