There are actually three different types of omega-3 fatty acids: ALA (alpha-linolenic acid), DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid). The preferred sources of omega-3s are DHA and EPA, the kinds found in seafood sources like nutritious salmon and sardines. (19) ALA, on the other hand, is found in many plant foods, including nuts and seeds and certain vegetables like Brussels sprouts.
And it’s not just walnuts, a study from the International Journal Of Obesity and Related Metabolic Disorders found that even when two groups of participants consumed the same amount of calories, the group which had more calories from fatty almonds lost the most weight. When it comes down to it, all nuts will be great sources of monounsaturated, polyunsaturated, and omega-3 fats, just in varying amounts. If you’re looking to slim down, read our essential guide to the best nuts for weight loss.
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.
Studies have found that avocados can lower levels of bad LDL cholesterol, boost anti-inflammatory properties, and improve vascular health. It’s very simple to add avocados to just about any salad. “Simply think portion control when integrating it into a weight-loss plan,” says Warren. If you’re concerned about how much fat you’re consuming or simply don’t prefer avocado on its own, try whipping up an avocado-based dressing. Toss an avocado, some Greek yogurt, and seasonings (we like fresh cilantro and parsley) into a blender and enjoy.
The one-time fish oil supplements can really help is if you need to reduce your levels of triglycerides, a dangerous blood fat linked to heart disease. The American Heart Association recommends that people with extremely high triglycerides get 2 to 4 daily grams of omega-3s (containing EPA and DHA) in capsules -- but only in consultation with their doctors.
Remember pancreatic lipase from earlier in the duodenum? Well, lipoprotein lipase breaks down triglycerides for absorption which goes into the fat tissue for storage, or it’ll be absorbed in muscle tissue for energy. Where do the chylomicrons go? Basically, they shrink so much that they just become tiny little particles that used to be. They’re absorbed into the liver and then the liver metabolizes them. The liver is key for fat metabolism! Liver health = fat digestion efficiency = healthy fat burning potential.
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. Don't forget to cook the pulp and eat it as well- the avocado seed is loaded with essential vitamins too! Don't let it go to waste!
The dietary reference intake (DRI) for fat in adults is 20% to 35% of total calories from fat. That is about 44 grams to 77 grams of fat per day if you eat 2,000 calories a day. It is recommended to eat more of some types of fats because they provide health benefits. It is recommended to eat less of other types of fat due to the negative impact on health.
Trans fats are typically found in highly-processed fatty foods such as crackers, cakes, donuts and pastries. Studies show that eating this unhealthy type of fat can have detrimental effects on health; one study in the New England Journal of Medicine even reported that each 2 percent increase in calories consumed from trans fats nearly doubled the risk of coronary heart disease. (39)
Eating foods rich in trans fats increases the amount of harmful LDL cholesterol in the bloodstream and reduces the amount of beneficial HDL cholesterol. Trans fats create inflammation, which is linked to heart disease, stroke, diabetes, and other chronic conditions. They contribute to insulin resistance, which increases the risk of developing type 2 diabetes. Even small amounts of trans fats can harm health: for every 2% of calories from trans fat consumed daily, the risk of heart disease rises by 23%.
Cheese often gets a bad-rap for being a high-fat food—especially hard, full-fat cheeses like Parmesan. While it is true that cheeses have more saturated fats than plant based foods, they (especially Parmesan, which contains 8 grams fat and 5 grams saturated fat per ounce), provide loads of other nutrients as well. In fact, Parm tops the cheese charts in terms of its bone-building calcium content, providing nearly a third of your daily calcium needs. Ounce for ounce, it has more protein than any other food—and yes, we are including meat and eggs on that list!
One medium avocado has approximately 23 grams of fat, but it is primarily monounsaturated fat. Plus, a medium avocado contains 40 percent of your daily fiber needs, is naturally sodium- and cholesterol-free, and is a good source of lutein, an antioxidant that may protect your vision. Try enjoying it in place of foods that are higher in less-healthy saturated fat—use 1/5 of a medium avocado to replace the mayo on your sandwich, the butter on your toast, or the sour cream on your baked potato. Keep in mind that they’re pretty high in calories, so you generally want to stick to no more than 1/4 an avocado at a time.
Dr. Michael and Dr. Mary Eades in their book Good Calories, Bad Calories write about the role that saturated fats found in butter and coconut oil play in immune health stating that the “loss of sufficient saturated fatty acids in the white blood cells hampers their ability to recognize and destroy foreign invaders, such as viruses, bacteria, and fungi”.
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.
Smear some toast or apple slices with peanut butter and you have a breakfast or snack with staying power. The unsaturated fats in peanut butter help make the meal satisfying by making it take longer to digest, and it’s also packed with protein. Stick to natural peanut butter to avoid the added sugars and unhealthy partially hydrogenated fats that are added to other kinds of peanut butter.
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.
Incorporating healing fats into your diet has many health benefits. Healing fats provide building blocks for cell membranes and hormones. They also function as carriers for important fat-soluble vitamins such as vitamins A, D, E, and K and aid in the absorption of minerals. Healing fats are essential for a healthy body and lifestyle. Let’s look more closely at several healing fats.
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.
A welcome addition for vegetarians and vegans, nuts and seeds are a terrific option for getting more healthy fats into your diets. For starters, they’re extremely easy to incorporate into your diet; they’re also fairly affordable and easily transportable, making them perfect for snacking. Aside from being a great source of healthy fats, nuts and seeds offer a wealth of benefits for our bodies. Regularly eating them can help lower bad LDL cholesterol to keep your arteries clear and your heart healthy. And like other foods rich in omega-3s, nuts and seeds are also considered brain foods, and certain types are even recommended to help improve mood and defeat depression. (21)
Canola oil, derived from the seeds of a plant in the broccoli family, has a near-perfect 2.5:1 ratio of omega-6 to omega-3 fats. According to a study review published in Experimental Biology and Medicine, people who achieve a dietary ratio similar to this have been able to battle cancer, arthritis, and asthma more effectively. The neutral oil is also rich in alpha-linolenic acid (ALA), an essential omega-3 fatty acid that may play a role in weight maintenance, according to a recent study.
Monounsaturated fats. When you dip your bread in olive oil at an Italian restaurant, you're getting mostly monounsaturated fat. Monounsaturated fats have a single carbon-to-carbon double bond. The result is that it has two fewer hydrogen atoms than a saturated fat and a bend at the double bond. This structure keeps monounsaturated fats liquid at room temperature.
