A recent at Ohio State University, carbohydrates can be more harmful than saturated fats. Saturated fats have long had a reputation for being linked to heart disease. This type of fat mainly comes from animal fat, including meat and dairy products such as beef, butter, cheese, pork, poultry with skin, lard, cream, and whole or 2 percent milk.  Carbohydrates are also known to be linked to an increased risk for heart disease and diabetes. When carbs are consumed in excess, they are converted into fat by the body.
