Eating for immunity: 7 winter foods your body will thank you for

Food has always been our most immediate form of medicine. In winter, when our immune systems face additional demands, choosing foods that actively support our body’s defences is one of the most practical things we can do for our health. The good news is that many of the most powerful immune-supporting foods are also some of the most delicious, comforting, and affordable things you can eat in the colder months.

Garlic

One of nature’s most potent antimicrobial foods, garlic contains allicin, a compound with demonstrated antiviral and antibacterial properties. Add it generously to soups, stews, roasted vegetables, and sauces.

Ginger

Warming, anti-inflammatory, and excellent for digestion. Fresh ginger grated into hot water with lemon and a little raw honey is a simple daily tonic, and one of the most time-honoured remedies for winter ailments.

Citrus fruit

June brings beautiful citrus into season in Australia: oranges, mandarins, lemons, grapefruit. All are rich in vitamin C, which supports immune cell function. Eat the whole fruit rather than juicing it to retain the beneficial fibre.

Leafy greens

Kale, silverbeet, spinach and English spinach are winter staples in Australia and are among the most nutrient-dense foods available. Rich in folate, iron, vitamins C and K, and antioxidants, they are excellent added to soups, stirred into dahl, or simply wilted with garlic.

Turmeric

The curcumin in turmeric is one of the most studied anti-inflammatory compounds in nature. A warming turmeric golden milk makes a beautiful evening drink. Simply combine plant-based milk, turmeric, black pepper, ginger and cinnamon.

Root vegetables

Sweet potato, carrot, beetroot, and parsnip are rich in beta-carotene, which the body converts to vitamin A which is essential for maintaining the integrity of respiratory tract membranes, the body’s first line of defence against airborne viruses.

Fermented foods

Plain yoghurt, sauerkraut, miso, and kimchi feed the beneficial bacteria in your gut, where over 70% of your immune system resides. Even a small daily serving makes a meaningful difference over time.
