I've been hearing conflicting information about the "good" kinds of fats, so I dug up this article that discusses fats, carbs, and heart health.
"Why hasn’t cutting fat from the diet paid off as expected? Detailed research—much of it done at Harvard—shows that the total amount of fat in the diet isn’t really linked with weight or disease. What really matters is the type of fat and the total calories in the diet. (7-15) Bad fats, meaning trans and saturated fats, increase the risk for certain diseases. Good fats, meaning monounsaturated and polyunsaturated fats, do just the opposite. They are good for the heart and most other parts of the body.
One problem with a generic lower fat diet is that it prompts most people to stop eating fats that are good for the heart along with those that are bad for it. Another problem is that when people cut back on fat, they often switch to foods full of easily digested carbohydrates—white bread, white rice, potatoes, sugary drinks, and the like—or to fat-free products that replace healthful fats with sugar and refined carbohydrates. The body digests these carbohydrates very quickly, causing blood sugar and insulin levels to spike. Over time, eating lots of “fast carbs” can raise the risk of heart disease and diabetes as much as—or more than—eating too much saturated fat. (16-18) That’s why it’s important to replace foods high in bad fats with foods high in good fats—not with refined carbohydrates."
