One of the best ways to strengthen your body’s defense against disease is to include plenty of fruits and vegetables in your daily meals. Fruits and vegetables are packed full of vitamins, minerals, and antioxidants that can help fight off infection and illness. Dark green leafy vegetables like spinach are particularly good for boosting immunity as they contain high levels of vitamin A which helps promote healthy cells in the body. Citrus fruits such as oranges and grapefruits are also great for strengthening immunity as they contain large amounts of vitamin C which help produce white blood cells that fight infection. Whole grains are another excellent addition to any meal plan as they provide a variety of important nutrients including magnesium, zinc, folate, selenium, B vitamins, iron, and fiber. These essential nutrients help support a strong immune system by helping produce healthy red blood cells which carry oxygen throughout the body. Aim for at least three servings per day of whole-grain bread or cereals such as oatmeal or quinoa for optimal health benefits. In addition to eating nutrient-rich foods like fruits, vegetables, and whole grains; incorporating more lean proteins into your diet may also be beneficial for maintaining a strong immune system. Lean proteins provide essential amino acids that build antibodies needed to fight infections in our bodies. Good sources include lean beef or pork cuts cooked without added fat or sodium; poultry such as chicken breast; fish such as salmon; eggs; beans; nuts & seeds; soy products like tofu & tempeh; Greek yogurt & kefir; plus wild game meats like venison & elk meat when available. Finally adding some healthy fats into your diet is another way to ensure that your immune system stays strong all year long! Healthy fats found in foods such as avocados, olive oil, coconut oil, nuts/seeds butter/ghee can help improve overall health by providing Vitamin E an antioxidant known for its anti-inflammatory properties plus Omega 3 fatty acids that aid in reducing inflammation throughout the body while protecting against disease-causing germs!
