A diet high in saturated fat -- found in animal products and some vegetable oils -- can lead to heart problems, but eating the right amount of unsaturated fats can protect the heart.
Unsaturated fats -- including monounsaturated and polyunsaturated fats -- are considered good-for-you fats. Polyunsaturated fats include the famed omega 3 and omega 6 fats, both considered essential fatty acids, because our bodies can't make them on its own. Polyunsaturated fats can help lower total cholesterol, while monounsaturated fats can raise "good" cholesterol, or HDL, and lower "bad" cholesterol, or LDL.
The average adult should get about 20 to 35 percent of their daily calories from fat and less than 10 percent of their daily calories from saturated fats, according to the Dietary Guidelines for Americans. A gram of fat contains nine calories, so a daily diet comprised of 2,000 calories would even out to about 44 to 78 grams of total fat a day.
So where can you find these unsaturated fats? Look no further than the six healthy picks below.
Almonds (And Other Nuts)
Salmon (And Other Fatty Fish)
If you're going to stick with the familiar, look for wild-caught salmon. A three-ounce serving of chinook (often the most expensive option, according to Eating Well), contains nearly 9 grams of fat, including nearly 4 grams monounsaturated and about 2.5 polyunsaturated. The milder coho salmon and the oilier sockeye both contain less, at around 5 total grams of fat, with nearly 2 grams each of mono- and polyunsaturated fat.
Olives (And Olive Oil)
Not an olive fan? The oil is an even more concentrated source of healthy fats -- just don't be too heavy-handed on your pour: A single tablespoon contains over 13 grams of fat, nearly 10 of which are monounsaturated and about 1.5 are polyunsaturated.
Flax (And Other Seeds)
Flax seeds also contain anywhere from 75 to 800 times more lignans, a component of plants that act as antioxidants, than other plant foods, WebMD reported.
A tablespoon of sesame seeds contains about 1.5 grams of monounsaturated fat and 2 grams of polyunsaturated fat. And an ounce of pumpkin seeds pack about 2 grams of monounsaturated fat and 2.5 grams of polyunsaturated fat.
