A lot of people believe that fat is harmful and we should avoid when we possibly can, especially when we are on a diet plan. Before we deny fat as a whole, we need to know that there is more than one kind of fat. And different kinds of fat may play different roles in human body.<\/p>\n

There is already agreement on artificial trans fat contributes to heart problems and diabetes[2]. The previous popularity of trans fit has been contained in the nation, especially in big cities like New York and Los Angeles[3, 4]. But debates continue on whether saturated fat is harmful and should be replaced with polyunsaturated and monounsaturated fatty acids. There is more evidence we can find in the literature associating saturated fat and cardiovascular disease. A meta-analysis published in 2010 synthesizing 21 prospective cohort studies showed that there is no link between higher saturated fat consumption and increased risk of CVD[5]. The studies chosen were relatively small in size and short in duration and thus studies of larger sizes and more years are still needed to assess\u00a0the effect of saturated fat. However, on the website of American Heart Association, saturated fat has already been categorized as bad fat along with trans fat[6]. It might be too early to make this judgement based on the available evidence. On the other hand, are there better substitutes than saturated fat? The AHA recommended polyunsaturated fat and monounsaturated fat. A newly published meta-analysis suggests that polyunsaturated fat might be a better option than both saturated fat and monounsaturated fat[7]. Certainly when trans fat goes out, something has to go in to replace it. What will\u00a0that be? For manufacturers,\u00a0this is usually saturated fat. The total fat amount in food before and after the trans fat ban did not change.<\/p>\n

Low fat is one of the biggest pitfalls about diet. While everybody knows that the excessive body fat contributes to development of chronic diseases, fats (except trans-fat), when consumed in a moderate amount, are actually protective of\u00a0bones, reproductive health, etc. It is not dietary fat, but\u00a0the excessive\u00a0body fat caused energy imbalance through a long period of time\u00a0that is\u00a0negatively affecting for public health.<\/p>\n
