A healthy immune system is essential for preventing illness and disease. Eating foods with the right vitamins, minerals and other nutrients will boost your immune system so that it is better prepared to fight viruses, bacteria and other toxins.
A well-balanced diet is essential for maintaining a healthy immune system, which is critical for warding off disease. Several vitamins and minerals play an important role in boosting the body’s inherent defenses. Many of these nutrients like selenium aid in the manufacture of glutathione, which helps prevent illness and lowers the incidence of infection. Other crucial nutrients include vitamins A, C, D and E as well as B-complex vitamins and trace elements, such as magnesium and zinc. When creating a meal plan, you should include foods that are rich in antioxidants that also contain glutamate, glycine and cysteine, which are amino acids that serve as building blocks for glutathione. Incorporating the following foods is a great way to provide your immune system the nutrients it needs.
Beans
In addition to being low in fat and calories, beans or legumes are rich in B vitamins, potassium and dietary fiber. They are an excellent source of glutamate and glycine. Beans contain health-promoting substances known as saponins, which clinical trials show reduce cholesterol and the blood glucose response. They also lower the incidence of kidney stones. A good source of protein for building healthy cells, beans can be substituted for several servings of meat each week. In addition to boosting your immune system, navy, pinto, red and black beans have anti-inflammatory properties. Beans can be added to chili, soups and salads. Eating a cup of beans each week also supplies nutrients like copper.
Broccoli
Broccoli and other cruciferous vegetables like arugula, bok choy, cauliflower and Brussels sprouts are rich in vitamins A, C and E as well as dietary fiber. They also contain disease-fighting phytochemicals and numerous other minerals like selenium. Studies show that these vegetables protect against cancer and reduce oxidative stress by boosting your immune system. Cruciferous vegetables contain the important nutrient sulforaphane, which enhances the liver’s ability to flush out toxins that can damage cells in your body. Broccoli also has antibacterial and antiviral properties.
Cold Water Fish
Wild, cold-water fish like cod, herring, salmon and tuna are a rich source of protein and omega-3 fatty acids. They are also low in saturated fat. Higher dietary intake of fish lowers the incidence of coronary artery disease, and cardiovascular mortality. Along with supplying glutamate and glycine, fish is also one of the few sources of vitamin D. Wild salmon contains astaxanthin, a potent antioxidant. Clinical studies have confirmed that the nutrient has a beneficial effect on the immune system. In addition to increasing strength and endurance, fish also improves cardiovascular health and eye health while lowering cholesterol.
Spinach
A popular superfood, spinach is packed with folic acid, beta-carotene and vitamin C, which improve the immune system. Along with antioxidants, spinach is also a good source of potassium and magnesium. These minerals help the body stay hydrated and manage energy levels. Spinach is also a good source of vitamins A and E. You can substitute kale and Swiss chard, which is high in beta-carotene and calcium as well as vitamins C and K.
Your diet should sustain the health and work of your immune system. Eating a healthy diet filled with a variety of foods that contain essential nutrients will improve your immune system and lower your risk of illness. Consuming nutritious food is a holistic way to protect your health. If fresh food is not available, frozen versions are a suitable substitute.
