Fried shells, fatty meats and piles of high-cal toppings can make tacos a belly buster. But they don't have to be; use our tips to give a healthier spin to this Cinco de Mayo favorite.

Whether it’s fast food or home cooking, the calories and fat in tacos can get crazy. Greasy cuts of meat and many of the classic fixings like cheese, sour cream and guacamole are high in fat. Home taco kits also come equipped with sodium-filled taco seasoning packets. A super stuffed taco could easily top 500 calories – and who eats just one?!

The fresher, the better! Use these tips to make tacos that are scrumptious and healthy.

• Swap nonfat Greek yogurt for sour cream.
• Keep the guac! Use about one tablespoon per taco for a dose of healthy fat.
• Replace fried shells with soft corn tortillas – you’ll save about 50 calories each.
• Pile on the salsa and hot sauce – little calories, big flavor.
• Season meat and fish fillings with chili powder and fresh citrus juice.
• Add veggies like grilled or roasted onions and peppers.
• Use a light sprinkle of low-fat shredded cheese.
