Here are nine foods well-known for their immunity-boosting qualities according to www.prevention.com.
Providing you can eat dairy without any side effects, the natural probiotics found in yogurt are great for keeping the GI tract healthy and in order. Opt for ones without added sugar or sweeteners if possible.
2. Oats and Barley
Adding oats to your diet in the winter is easy, you can start your day with a hot bowl of oatmeal and you can switch barley for rice with your evening meal. Both of these grains are gentle on the stomach and are high in antioxidants — important for fighting off those winter bugs.
Beef is full of zinc, which many of us are low in over the winter months. Zinc helps to form healthy white blood cells which are important in the fight against winter illnesses. To get the most out of beef aim for organic, grass-fed beef at a frequency of 1-2x per week.
For optimum garlic intake, you should eat two cloves of raw garlic a day. However, if this sounds unpalatable then you can either take garlic capsules or use lots of garlic in your cooking. The allicin in garlic is great for helping to fight off colds and flu.
5. Sweet Potatoes
Full of beta-carotene which is great for your skin, sweet potatoes make a healthier alternative to regular potatoes and are much lower on the GI scale.
6. Oily Fish and Shellfish
Oily fish such as salmon, mackerel and herring are great sources of omega-3 fatty acids, which can help protect the lungs from infection. The selenium found in shellfish such as prawns, oysters and mussels increases the amount of cytokines in the white blood cells, which helps fight off winter ailments.
Mushrooms are also good for keeping our white blood cells healthy, and they are a great source of vitamin D — which is in short supply in the winter months. Add some to your favorite dishes for an immune boost.
8. Chicken Soup
The go-to meal when you’re feeling under the weather, research shows that we should be eating chicken soup as a preventative dish as well as a restorative one. The salty brine helps to thin mucus, and the onions and vegetables added to the soup also provide infection-fighting nutrients.
Black and green tea both contain lots of cold-busting antioxidants, even the decaffeinated varieties. Add lemon and honey instead of milk and sugar for a blast of vitamin C and antibacterial goodness.
