• Can help reduce risk of chronic diseases (e.g., heart disease, diabetes)

Preparation and Cooking Methods

• Washing and cleaning: important to remove dirt, bacteria, and pesticides
• Steaming and boiling: retain nutrients and color
• Roasting and grilling: enhance flavor and texture
• Stir-frying and sautéing: quick cooking methods for tender vegetables

Common Vegetables and Their Uses
