Healthy nutrition plays a vital role in supporting the human immune system. A balanced diet is one of the most important factors that helps the body resist diseases and infections. With increasing health challenges, such as the spread of viruses and epidemics, it has become essential to focus on boosting immunity by consuming foods rich in essential nutrients. --- The Importance of Nutrition for Immunity: The immune system consists of a complex network of cells and organs that work together to protect the body from microbes and viruses. For this system to function efficiently, it needs a range of vitamins and minerals that we obtain from food. Poor nutrition weakens immunity and makes the body more susceptible to disease. --- Nutrients that Strengthen Immunity: 1. Vitamin C Found in citrus fruits such as oranges and lemons, it is known for its role in stimulating the production of white blood cells that fight infection. 2. Vitamin D Helps regulate the immune response and can be obtained from sunlight and some foods such as fatty fish and eggs. 3. Zinc Essential for the growth of immune cells and found in meat, nuts, and legumes. 4. Proteins Form the building blocks of antibodies and are found in meat, grains, eggs, and dairy products. 5. Fiber and Antioxidants Help promote digestive health, which is the first line of defense for immunity. They are found in vegetables, fruits, and whole grains. --- Immune-Boosting Lifestyle in Addition to Diet: Get enough sleep Exercise regularly Avoid smoking and alcohol Reduce stress and anxiety --- Conclusion: Healthy nutrition is not just a way to prevent disease; it is the foundation of a strong and healthy body. By choosing nutritious foods and avoiding harmful eating habits, we can boost our immunity and enjoy better health in the long run. Remember, "prevention is better than cure," and good food is the first line of defense against illness. Al-Mustaqbal University, the leading university in Iraq.
