Good For You: Coriander (known as cilantro in its leafy form) is a powerful bacteria fighter. A recent study found that oil from coriander seeds—which destroys dangerous cells by damaging their membranes and interfering with cellular respiration—is effective in wiping out strains from E. coli to salmonella.
Tastes Great, Too: Add the seeds to everything from fruit salads to pasta. Or try culinary nutritionist Tricia Williams's trick of steeping toasted coriander seeds in olive oil, then tossing quinoa in the flavored oil.
