Monounsaturated fats are typically liquid at room temperature but solidify if refrigerated. These heart-healthy fats are typically a good source of the antioxidant vitamin E, a nutrient often lacking in American diets. They can be found in olives; avocados; hazelnuts; almonds; Brazil nuts; cashews; sesame seeds; pumpkin seeds; and olive, canola, and peanut oils.
Monounsaturated fats are considered one of the healthiest types of fats to eat, and are the backbone of the Mediterranean diet. They are found in olives, olive oil, avocados, nuts, nut butters, as well as sesame oil, peanut oil, and canola oil. (Be aware that most Canola oil in the US and Canada is GMO unless specifically labeled as non-GMO or organic.)
Out of all lean meats, duck has the highest level of a muscle-building form of polyunsaturated fat called arachidonic acid, or AA. Supplementation of arachidonic acid has been shown to increase lean body mass, strength and anaerobic power in men. In a study at the University of Tampa, men who took AA gained 3.4 pounds more lean muscle mass than those who took a placebo. Keep bumping up the burn with these best foods for a toned body.
A healthy immune system is essential if we want to stay free of bacteria and infections like the common cold. Fats help your immune system by aiding the body’s ability to absorb antioxidants and vitamins. Nuts, seeds, green vegetables and grains are a great source of Alpha-lipoic acid and Omega 3 which help reduce inflammation in the cells, reduce cell death and regenerates antioxidants. Coconut oil is another fat with immune boosting properties. It contains lauric acid and caprylic acid which fight the overgrowth of yeast and prevent infections.
Saturated fats are found in animal products (meat, poultry skin, high-fat dairy, and eggs) and in vegetable fats that are liquid at room temperature, such as coconut and palm oils. The 2005 Dietary Guidelines recommend limiting saturated fats to 10% or less of your total calories, while the American Heart Association recommends keeping them to just 7% of total calories.
Of course, these healthy fats are still fats — according to government guidelines, they should make up no more than 20 to 35 percent of your overall calorie intake. But a good rule of thumb is to choose monounsaturated fats in place of unhealthy saturated fats and trans fats whenever possible. The American Heart Association says saturated fats should make up no more than 7 percent of your total intake. To get more healthy fats, here are the foods you should focus on.

Cutting back on saturated fat will likely have no benefit, however, if people replace saturated fat with refined carbohydrates. Eating refined carbohydrates in place of saturated fat does lower “bad” LDL cholesterol, but it also lowers the “good” HDL cholesterol and increases triglycerides. The net effect is as bad for the heart as eating too much saturated fat.
Is olive oil good for you? Believe it or not, the olive oil benefits are so profound that almost any diet should include it. First, extra virgin olive oil (EVOO) is great for heart health. In fact, olive oil consumption has been linked to lower blood pressure, reduced cholesterol levels and improved blood vessel function. (14, 15, 16) The high amount of antioxidants in EVOO means it protects your cells from damage. It also helps improve memory and cognitive function and works as an anti-inflammatory agent. (17) Since inflammation is at the root of most diseases, this is a biggie! (18)
There are two basic kinds of fat, saturated and unsaturated. Unsaturated fats are considered “healthy fats” include both polyunsaturated and monounsaturated fats. These types of fats are typically found in vegetable oils that are liquid at room temperature, fatty fish, (salmon, trout, catfish, mackerel), and nuts and seeds. Polyunsaturated fats include Omega-3’s that are the building blocks of cell membranes I mentioned earlier. Omega-3’s also give your body energy and help support your hormones and immune system (3).
Fat tends to be considered “bad” because it is associated with weight gain and high cholesterol. However, certain types of fat give protective benefits to the heart if appropriate portions are consumed. The key is to understand how to choose the right amount of each type of fat, so we should look closely at the ideas of total fat and each type of fat.
While the guidelines called for more carbs in the form of fruits, vegetables and whole grains, what the average American understood was that carbs — any kind of carbs — were good (even refined carbohydrates!) and all fat was bad. The food industry pounced and high-carb, low-fat foods became the norm. Grocery store shelves and refrigerators were soon lined with low- and no-fat items that were packed with sugar to help enhance the flavor. Not coincidentally, both a sugar addiction as well as an obesity epidemic in America began soon after low-fat diets became the standard recommendation.
Avocado: One of the most widely known healthy fats, avocado makes an ideal addition to any dish at breakfast, lunch or dinner. It's also perfect as a stand alone snack! This powerhouse of a superfood isn't only a monounsaturated fat – it's also loaded with folate, potassium, fiber and vitamins E, C and B6.
