Even as coronavirus (COVID-19) has infected populations across the world, many people have questioned what protective measures they can take to protect their health. You may lessen your risk of catching COVID-19 as well as other viruses, bacteria, and diseases by using a face mask, getting inoculated if possible, cleansing your hand often, avoiding contact of sick individuals, and improving care hygiene.
There is evidence, however, that eating patterns and other lifestyle decisions influence immune function and illness susceptibility. Whether these approaches have an impact on COVID-19 vulnerability or its disease symptoms is yet unknown. There are other reasons, though, to put what we now know about diet and immune systems to use. The following is what is commonly understood:
A Healthy Diet
A plant-based, low-fat diet may provide immune support. White blood cells that create antibodies are crucial to the immune system’s ability to fight off bacteria, viruses, or other foreign invaders. Vegans are reported to possess higher robust white blood cells than non-vegetarians since they consume more vitamins and less fat.
A low-fat diet could also be beneficial. Lowering dietary cholesterol has been shown in studies to strengthen immune systems. Studies further indicate that oil may impair the efficiency of white blood cells and that high-fat meals may alter the gut microbes that boosts immunity.
A healthy weight may also be advantageous for the immune system. Obesity has been related with an increased chance of pneumonia as well as other ailments, including the flu. Because they are high in fiber, which keeps you full without consuming more calories, plant-based diets are beneficial at helping people lose weight. In addition to lowering BMI, fiber can help boost immunity. It has also been demonstrated that a plant-based diet lowers inflammatory biomarkers.
Eat Vitamin-, Mineral-, and Antioxidant-Rich Foods
According to research, meals such as veggies and fruit contain vitamins C, E, and beta-carotene, minerals that can help the immune system. Since several fruits, veggies, as well as other plant-based diets are full of antioxidants, they help to reduce oxidative stress. Fruits like elderberry makes a great choice.
Because it increases the body’s disease-fighting cells, beta-carotene is a potent antioxidant that can lower inflammation and improve immunological function. Sweet potatoes, carrots, and green leafy vegetables are also great sources.
According to research, taking vitamin D supplements may lower your chance of developing viral infections, such as respiratory tract infections, by lowering your body’s production of proinflammatory substances. Increased blood levels of vitamin D have been associated with reduced risk of cardiovascular disease, hepatitis, and other chronic diseases like tuberculosis. Cereals that have been fortified, plant-based milks, and supplements are food sources of vitamin D.
White blood cells, that protect the body against invaders, can be boosted with the help of the mineral zinc. Nuts, sesame seeds, pumpkin seeds, beans, and lentils are examples of sources.
Vitamins C and E
Antioxidants like vitamins C and E work to combat free radicals and strengthen the body’s immune system. Red peppers, oranges, strawberries, broccoli, mangoes, lemons, and other fruits and vegetables are sources of vitamin C. The foods spinach, broccoli, almonds, and seeds are good sources of vitamin E.
