Instead of only looking at the amount of total fat grams in a product, look at the types of fat, which is generally more important—although a higher number of fat means more calories, regardless of the source. For heart health, seek out products (such as this plant-based buttery spread) that contain more unsaturated fats in proportion to saturated fats. Additionally, because some (but not all) scientific evidence suggests polyunsaturated fats, although heart-healthy, are more vulnerable to oxidation and may promote inflammation, look for oils and spreads that contain more monounsaturated fats, such as this one.
