If you’re unlucky, you’re already fighting a cold. If you’re lucky, you’ll make it through the rest of the season without catching one. So how can you be one of the lucky ones?
The best way to ward off a cold and flu virus is to bolster your immune system and look no further than your refrigerator.
Here are three foods to boost your immune system that you can add to your diet today.
It’s one of the few foods that serves up vitamin D, a nutrient that triggers and arms the body’s T-cells, immune cells that kill invading bacteria and viruses, including the influenza virus. Six ounces of cooked salmon (sockeye) delivers 890 IU (international units) of vitamin D. Not bad, considering one cup of vitamin-fortified milk has 100 IU.
This squash is an exceptional source of beta-carotene, a phytochemical the body converts to vitamin A. Vitamin A, in turn, helps maintain a strong intestinal lining – a physical barrier against pathogens – and ensures immune cells work properly.
Thanks to its natural sulphur compounds, this flavourful herb increases the production and activity of many immune cells, including white blood cells, antibodies and other natural killer cells. Garlic also has antiviral and antimicrobial properties.
