The oils you cook with are a great way to incorporate healthy fats. For high-heat cooking, coconut and avocado oils are best because they have a higher smoke point, the temperature at which the fat or oil begins to break down due to heat. Avocado oil has the highest smoke point (570 degrees). The smoke point of ghee is 485 degrees and extra virgin coconut oil is 350 degrees.
The body is able to turn ALA into usable DHA and EPA to some degree, but this isn’t as efficient as getting DHA and EPA directly from food sources that provide it. Even after extensive research, it’s not totally clear how well ALA converts into EPA and DHA or if it has benefits on its own, but health authorities, like those at Harvard Medical School, still consider all sources of omega-3s crucial in the diet.

Fat droplets start to pass through the duodenum where bile acids are added (bile acids are from cholesterol in the liver and stored in the gall bladder). Bile acids are really cool because they act like soap breaking and emulsifying the fat droplets and making them into even smaller droplets. I like to use the visual of washing a pan with grease on it with soap, at first the grease barely comes off, but with a little muscle and scrubbing with soap the detergent breaks up the fat and grease into very small particles until it’s gone.
Ideally, you’ll want to consume minimally-processed foods that are full of heart-healthy, polyunsaturated omega-3 fatty acids (ALA, DHA, and EPA), monounsaturated fats (OEA), and the trans fat conjugated linoleic acid (CLA), as well as some medium-chain saturated fats like stearic acid and lauric acid. On the other hand, stick to foods that have low levels of omega-6 fatty acids and other saturated fats (palmitic acid), and zero manmade trans fats (partially hydrogenated oil). According to the Dietary Guidelines, an easy way to do this (besides following this list) is to lessen consumption of the top sources of saturated fats like pizza, burgers, meats, and processed snacks and sweets.
Following a high monounsaturated fat diet can be beneficial for improving insulin sensitivity in both individuals who have, or do not have high blood sugar levels. One study found that following a high monounsaturated fat diet for three months managed to improve insulin sensitivity by up to nine percent (14). This was followed by another study which found participants who had metabolic syndrome and followed a high monounsaturated fat diet for twelve weeks had a significant reduction in insulin resistance (15).
Saturated fatty acids constitute at least 50% of our cell walls and offer protection against unwanted materials invading the structural integrity of the cell wall. Saturated fats promote bone health by helping utilize calcium. Saturated fats also protect the liver from toxicity, help fight off fungal and other infections, and boost our immune systems.
It’s in your best interest to learn and put these mindfulness exercises into practice. Now that our habitat has become too technological and many people just don’t want to unplug, engaging in daily prayer, celebrate your friends’ victories, and listening to your spouse are among the best ways to be mindful about what you are doing and how you are living.
Nuts like pecans, pistachios, cashews, and almonds also pack a lot of healthy fats. Almonds are the richest in vitamin E, and pistachios have lutein and zeaxanthin, carotenoids important for eye health. All you need to eat is a 1/4 cup serving per day to reap the benefits. Some varieties are fattier than others, like cashews and macademia nuts, so you need to pay closer attention to serving sizes. (Nuts have, on average, 45 grams of fat per cup.) Nutritionists love pistachios because the fact that you have to shell them helps you eat slower and naturally control portion size. The peanut (technically a legume) contains monounsaturated fats but all of its polyunsaturated fats are omega-6s, which evidence suggests may not do us any favors.
The worst type of dietary fat is the kind known as trans fat. It is a byproduct of a process called hydrogenation that is used to turn healthy oils into solids and to prevent them from becoming rancid. Trans fats have no known health benefits and that there is no safe level of consumption. Therefore, they have been officially banned in the United States.
For decades, doctors, nutritionists, and health authorities have told us that a diet high in saturated fats raises blood cholesterol and increases the risk of heart disease and stroke. However, recent studies have made headlines by casting doubt on those claims, concluding that people who eat lots of saturated fat do not experience more cardiovascular disease than those who eat less.
Not only does coconut oil top the charts as one of the healthiest cooking oil options, but you can also apply coconut oil on your skin or use coconut oil for your hair as well. It’s rich in medium-chain fatty acids, which are easy for your body to digest, not readily stored by the body as fat and small in size, allowing them to infuse cells with energy almost immediately.

The reality is, not all fats are created equal. Some are downright bad (like trans fats in margarines), some are misunderstood (like the saturated fat, lauric acid), and some fats are health heroes (like omega-3s). And, don’t get us wrong, eating foods that are packed with the wrong kinds of fat will make you fat, but with all the omegas, and monos, and polys out there, it can be kind of confusing which are which. To make things easier for you, we here at Eat This, Not That! found the best foods with good fats that you can add to your diet. But before you go off on a high-fat binge, remember that—like all food—even these healthy fats should be consumed in moderation.
Salmon might not get as bad of a rap for being high in fat, but its health benefits are worth repeating. By adding this fish fillet into your diet just twice a week, you’ll get the full amount of heart-healthy omega-3 fatty acids recommended by the American Heart Association. Omega-3s reduce the risk of arrhythmia, decrease triglyceride levels, and can actually slightly lower blood pressure. When you’re at the fish counter, make sure to pick up the right kind—while pink salmon is the second best fish for nutrition and health benefits, farmed Atlantic salmon is one of the worst.
