英語時差:喂熱餓冷
Is it "feed a fever, starve a cold?" or vice versa. Yael and Don try to clear that up on this Moment of Science. Y: Don, have you heard the saying, "feed a fever, starve a cold"?
D: Sure. But, it's "starve a fever, feed a cold." Why? Are you sick?
Y: No. Someone wrote in a question, and I can't remember which way it goes. How do you remember it?
D: It's an old saying. It goes back hundreds of years to ancient medicine. The idea is that if you're hot, you need to put less fuel into your body so you'll cool off: starve a fever, and if you're chilled or weak, you need to eat to stoke up your internal fires: feed a cold.
Y: You're kidding. Does it work? It sounds a bit wacky to me.
D: Well, the starving/feeding part isn't really a good idea. When you're sick, your appetite often decreases because food doesn't taste as good and you're tired. Fighting off a cold or flu demands energy. You're best off eating light, healthful food --whole grains, protein, veggies--soup and, of course, drinking lots of water. A healthy diet everyday--rich in vitamin C and antioxidants--has been shown to help boost immunity, too.
Y: My mom used to feed me ice cream when I was sick.
D: Oh well, ice cream's a special case.
Y: Cookies, too?
D: Yeah!
