Recent research has confused the average consumer by blurring the lines between saturated fat intake and heart disease. On one hand, some studies report that there is not enough evidence to support the long-standing theory that saturated fat increases the risk of heart disease.  To make matters worse, the headlines of popular magazines have brazenly encouraged the public to eat more butter. On the other hand, some studies definitely state that reducing your intake of saturated fats (like butter), will decrease your risk of heart disease. Why the discrepancies?  The American Heart Association released a presidential advisory that has reviewed the current set of literature on the topic, and, has set the record straight once and for all.

In short, the advisory reports that, “lowering [your] intake of saturated fat and replacing it with unsaturated fats, especially polyunsaturated fats, will lower [your] incidence of CVD (cardiovascular disease)”.  So how did those other researchers come to a different conclusion?  The advisory aptly pointed out that the main reason for the conflicting results lied in how saturated fat was compared. It went on to say that when lower intakes of saturated fat were replaced with mostly refined carbohydrates and sugars, there was no decrease risk of CVD. In other words, the studies that suggest butter does not increase risk of heart disease, compared butter consumption to an unhealthy mix of refined grains, soda, red meat, trans fat etc.  It’s no wonder their findings showed that cutting out butter did not decrease the risk of CVD – because the replacement diet in itself had plenty of other CVD risk factors! Clearly this is something the headlines missed.

So what’s the bottom line? Butter is mostly saturated fat, and limiting your consumption of it, and replacing it with plant-based fats, such as extra virgin olive oil, can decrease your risk of cardiovascular disease.
