Kimchi
The Benefit: A standby for centuries in Korean culture, this spicy fermented cabbage dish acts like a tonic for your gastrointestinal tract. A 2005 Seoul National University study found it’s so beneficial to the immune system that it helped speed recovery in chickens stricken with the virulent avian flu.
Healthy Tip: Add kimchi to organic mashed potatoes, rice, or salads if the distinctly sour, fizzy fare isn’t appetizing to you on its own.
