Immunity Boosting Foods For Adults #1: Turmeric

If you want to improve immunity in adults, then this is the first spice you should turn to. Thankfully, Indians are no strangers to turmeric, as almost all of our native foods, from dal to sabzis, are cooked using turmeric. The main active ingredients in turmeric, curcumin and theracurmin, help build immunity and provide relief from cough, cold and sore throat. It can also reduce hay fever symptoms like sneezing, itchy runny nose, and congestion. 

The body cannot absorb the benefits of turmeric as-is, though - it needs to be combined with some kind of fat and black pepper for better absorption. This makes haldi-doodh or turmeric milk a good option to gain maximum benefits from turmeric. All you need to do is whisk together 1 cup milk, 1 one-inch piece of turmeric and 3 whole peppercorns with 50 ml water in a saucepan. Bring it to a low boil. Reduce the heat and simmer for 10 mins, then strain and serve!
