probiotics and prebiotics. let’s start with probiotics and prebiotics, which give your immune system a boost and keep the gut microbiome in check. it’s important to eat foods that foster the growth of good bacteria to produce the right kind of immune cells for our overall health. probiotics are found in fermented foods like yogurt, kefir, sauerkraut and apple cider vinegar. prebiotics naturally stimulate the intestinal tract and feed the probiotic flora in the body. prebiotic soluble fibre is found in jerusalem artichokes, chicory root, berries, garlic, raw oats, asparagus and leeks.
vitamin c. it’s no surprise that consuming foods high in vitamin c helps fight infection because they stimulate white blood cell production. oranges and tangerines are the usual choices, but sweet red pepper, spinach, broccoli, strawberries, kale, kiwi and amla berries are also excellent sources of vitamin c too. oregano oil is a great choice, but it needs to first be diluted.
mushrooms. another good source of protein and many vitamins (like vitamin d) and minerals, mushrooms also contain beta-glucans, a type of fibre that research has shown can help boost the immune system. reishi, maitake and shiitake are excellent choices.
