After years of having low-fat and no-fat foods pushed at us, it's no wonder that some people are a bit confused over the concept of a healthy fat. The American Heart Association has a fun way to clear up the confusion; meet the Better Fats Sisters:

• Mon. Short for monounsaturated fat, Mon is found in fish, seeds, nuts, avocado, and vegetable oils. Mon offers some heart health benefits but, as all fats are high in calories, it's important to practice moderation.
  
• Poly. Short for polyunsaturated fat, Poly is a heart helper like her sister; she can help lower your bad cholesterol.
  
  

Nutrition labels usually only list total fat grams, saturated fat and trans fat. To estimate how much monounsaturated or polyunsaturated fats are in a product, just subtract the saturated and trans fat from the total fat. Want more of the skinny on fats? Check out AOL Health.
