Good fats can cut risk of death by 27%, study says
"Bad" fats include trans fats and saturated fats. Saturated fats are common in the American diet, in red meats and full-fat dairy. Research in this area has been mixed, with some studies finding that whole-milk dairy products could be linked to less body fat and obesity, possibly because they promote feelings of fullness and therefore less is consumed. A recent study associated dairy and butter with lower rates of diabetes, although it still found a 1% higher risk of death per tablespoon of butter.
Trans fats are the major culprit when it comes to health problems. Though they can be found naturally in small amounts in meat and dairy products, the major sources are from artificial trans fats used in processed foods.
The Food and Drug Administration banned trans fatsfrom products in 2013, but they can still be found in many foods like crackers, cookies, doughnuts, muffins, pies and cakes, often in trace amounts that quickly add up. Research from the Harvard School of Public Health has showed that the risk of heart disease rises by 23% for every 2% of calories obtained from trans fats.
