Foods:
I’ve saved the best until last, we can control the food we eat, the food we eat will directly impact our gut health and as stated at the start: 70% of our immune system comes from the gut.
I’m a massive fan of using food as medicine, so here are some useful foods and the why:
1. Foods that support your immune system
Kale – rich in glucosinolates which induce phase II detox pathways and activate Nrf2 (buffer oxidative stress). Good source of vitamin C, vitamin K, vitamin A, & folate.
Strawberries – rich source of vitamin C and the polyphenol, ellagic acid, which modulate Nrf-2 activation.
Brazil Nuts – rich in selenium which is crucial for a functioning immune system & thyroid.
Wild Salmon – high in anti-inflammatory long chain omega-3 EPA/DHA fats, rich in B12, selenium, vitamin D, calcium.
Pumpkin Seeds – rich plant source of zinc, which is important in a robust immune system
Oranges - rich in vitamin C, bioflavonoids, quercitin, and naringin. Limonoids in citrus promote glutathione production.
2. Foods that strengthen your immune system
Ginger - anti-nausea and anti-inflammatory herb that has stomachic, expectorant, anti-tussive properties.
Manuka Honey - a anti-microbial agent, a natural cough suppressant, and packed with antioxidants.
Turmeric - the active compound curcumin is a potent anti-inflammatory compound and immune modulator of T-lymphocytes.
Apple - rich in the flavonol quercetin, a potent anti-inflammatory compound, antioxidant, and mast cell stabilizer.
Bone Broth – used historically for immune support. Rich bioavailability of nutrients zinc, calcium, phosphorous, and gut soothing GAGs.
Bell pepper – rich source of vitamin C, a potent antioxidant and recycler of other antioxidants in the body.
3. Immunomodulatory foods via the gut microbiome (foods that can influence the immune system via the bacteria in the gut)
Garlic and Onion - known for containing organosulfur compounds which play an important role in upregulating antioxidant defence systems.
Fermented Foods – Kimchi, Kefir, Sauerkraut - stimulate defensins and other immunomodulatory peptides, which enhance our immune system and improve immune tolerance.
