3. Honey
It’s deliciously smooth, yes, and it can help soothe a burning throat that feels raw. But honey’s best feature is one that you can’t taste — a few teaspoons in tea can provide much needed antibacterial and antimicrobial agents to help fight off any infectious colds. A 2017 clinical review published in Pharmacognosy Research suggests honey may help the body fight off everything from throat infections to tuberculosis.
4. Kale
Kale is a nutrient-dense food with tons of vitamins and minerals including vitamin A, vitamin C, vitamin K, vitamin E, iron, manganese, calcium, and potassium. Eating a diet rich in micronutrients, like the ones that kale provides, helps boost your immune system and prevent you from getting sick, according to Harvard Health Publishing.
