Firm, buttery and rich in flavor, avocados are a nutritional powerhouse. They're a good source of monounsaturated fats, which help reduce LDL cholesterol and triglycerides. They're also a good source of fiber, which helps you feel full and promotes healthy digestion. If you're looking for a fruit that's as versatile as it is nutritious, avocados are for you. They're perfect for making creamy guacamole, or try adding them to your favorite omelet or sandwich. They also make a great substitute for mayonnaise in tuna salad or egg salad.
