Although the word 'fats' carries a negative notion, not all fats are bad. Some fats such as monounsaturated fats are good for the body. Found in olive oil, canola oil, lean beef, nuts, avocados, etc., these fats are fatty acids featuring one double bond in their fatty acid chain. They have several positive effects on the human body and their benefits include the ability to decrease the risk of contracting various diseases.
