Eating Your Way to Immunity This Winter
Winter has a way of catching us off guard — one day you’re feeling fine, and the next you’re reaching for the tissues. While we can’t always avoid every bug, what we eat can play an important role in supporting how our body responds and recovers.
Here are some key nutrients to focus on this season, along with simple foods that can help deliver them.
Vitamin C: The Barrier Builder
Vitamin C is one of the most well-known immune nutrients, and for good reason. It supports the epithelial barrier, which is your body’s first line of defence against pathogens (think: the lining of your airways and gut).
It also supports the production of lymphocytes and phagocytes — white blood cells responsible for identifying and helping destroy foreign invaders.
Simple source: Add a kiwi fruit to breakfast or squeeze lemon over your lunch.
Vitamin E: The T-Cell Supporter
Vitamin E is a powerful fat-soluble antioxidant that plays an important role in T-cell function.
T-cells are immune cells that help coordinate your body’s response to infection and support your immune memory, helping your body respond more effectively in the future.
Simple source: Add almonds on top of salads or pair them with fruit as a snack.
Selenium: The Anti-Inflammatory Mineral
Selenium is a trace mineral that often flies under the radar, but it plays an important role as both an antioxidant and anti-inflammatory nutrient.
It supports the activity of selenoproteins — enzymes that help protect cells from oxidative damage and support immune function.
Simple source: Add mushrooms to soups, stir-fries, pasta, or omelettes — sliced or minced.
Hydration: Don’t Overlook the Basics
During winter, thirst cues can decrease because we often sweat less and feel less hot, meaning many people become mildly dehydrated without realising it.
Your body relies on adequate fluid intake to transport nutrients, support immune cells, and maintain the mucosal linings of your airways and digestive system, which act as physical barriers against infection.
Herbal teas like peppermint, ginger, or lemon and honey tea are a warming way to keep your fluids up during the cooler months.
