Corn adds fiber, onions supply allyl sulfides, and tomatoes contribute lycopene to this nutrient-rich salsa - all are cancer-fighting ingredients.

This salad is a celebration of color and taste. It may be made in advance and keeps well for several days. It is nearly fat free, which is important when it comes to lowering cancer risk and improving survival.

Gazpacho, a cold tomato-based soup, and this low calorie guacamole with corn chips, make a light, summertime lunch.
