6. Chicken soup
Mom’s special recipe always seemed to make you feel better when you had a cold, and now researchers have proven that chicken soup is not just a placebo. It seems that the particular combination of ingredients inhibits the production of mucus. The steamy broth helps to clear sinuses, and it’s packed with electrolytes. If your recipe includes plenty of vegetables, it’s also delivering antioxidants, which boost immunity. So it seems that mother did know best, after all.
