Adding eggs with the yolk offers a tremendous amount of benefits. “Current research proves that eggs contribute a boatload of nutrition, including riboflavin, folate, and vitamins D and B12 that can lower the risk of heart disease,” shares Warren. Eggs get a bad rep because they contain cholesterol and saturated fat. But research shows that the cholesterol in eggs (and in the diet in general) doesn’t necessarily contribute to cholesterol in the body. Warren also points out that studies highlight the importance of being cognizant of total saturated fat in the diet, regardless of whether it is from an egg yolk or not. One large egg actually only contains 1.6 grams of saturated fat.
Omega 3 fatty acids and omega 6 fatty acids are both a type of polyunsaturated fat. For a healthy body, omega 3 and omega 6 fatty acids need to be eaten in about a 1:1 ratio. However, the standard American diet contains about 15 to 16 times as many omega 6s as omega 3s, so the ratio is way out of whack. Omega 6 fatty acids eaten in a high concentration like that become pro-inflammatory and promote heart disease.
One cup of black olives has 15 grams of fat, but again, it is mainly monounsaturated. Plus, no matter what variety of olive you enjoy, they all contain many other beneficial nutrients as well, such as hydroxytyrosol, a phytonutrient that has long been linked to cancer prevention. New research is showing that this phytonutrient may play a role in reducing bone loss as well. And if you have allergies or other inflammatory conditions, olives might be just the snack for you as research suggests that olive extracts function as anti-histamines on the cellular level. Even with all these benefits, it is important to be mindful of your serving size as olives can be high in sodium. Stick to 5 large or 10 small olives as the perfect portion.
In other parts of the world, fat has always been welcome at the table. In the U.S., though, we’re only now realizing the truth: not all fats are created equally. Our bodies need fat — more specifically, they need healthy fats. And as high-fat diets like the ketogenic diet continue to gain widespread popularity, more and more people are eager to know what fats qualify as healthy.
You'll primarily find saturated fat in animal-derived foods, particularly fatty red meat and processed meat. And while recent research has called into question exactly how big of a negative impact saturated fat has on your health, Harvard recommends replacing sources of saturated fat with unsaturated fat. Grilling up salmon instead of a burger, for example, fits the bill.
Although fat is an essential part of the diet, keep in mind that most high-fat foods are also considered calorie-dense foods. When increasing your intake of healthy fats, it’s important to account for this by making modifications to your diet, such as decreasing your intake of refined carbs or sweets. Without making a few simple swaps to your diet, adding high-fat, high-calorie foods can lead to weight gain.
Today’s Basics topic is all about fat! We’ve covered other macronutrients here on the Nutrition Stripped blog such as carbohydrates, protein, and digestion, and now the list is growing! Out of all the macronutrients, people have the most misconceptions about by fat! Today I’m sharing a breakdown of food sources of healthy fats, the function of fat in the human body, how fats are digested, and how our bodies store fat. If I haven’t lost you yet, keep reading on to learn the basics of healthy fat from a dietitian’s point of view. Let’s jump in!
It’s not as high in fat as the other foods on this list, but tofu is still a good source of monounsaturated and polyunsaturated fats. A modest, 3-ounce portion of super firm tofu contains 5 to 6 grams of fat and about 1 gram of saturated fat, but this is naturally-occurring fat from the soybeans, and tofu is considered a health food for a reason. It's a solid plant-based protein that’s low in sodium and provides nearly a quarter of your daily calcium needs. Check out these 11 delicious recipes that are perfect for tofu first-timers.
Trans fat. Small amounts of naturally occurring trans fats can be found in meat and dairy products but it’s artificial trans fats that are considered dangerous. This is the worst type of fat since it not only raises bad LDL cholesterol but also lowers good HDL levels. Artificial trans fats can also create inflammation, which is linked to heart disease, stroke, and other chronic conditions and contributes to insulin resistance, which increases your risk of developing Type 2 diabetes.
Consuming high levels of calories – regardless of the source – can lead to weight gain or being overweight. Consuming high levels of saturated or trans fats can also lead to heart disease and stroke. Health experts generally recommend replacing saturated fats and trans fats with monounsaturated fats and polyunsaturated fats – while still maintaining a nutritionally-adequate diet.
Trans fats are unsaturated fats that have been processed and as a result, behave like saturated fats. Eating trans fats increases the levels of ‘bad’ cholesterol and decreases the levels of ‘good’ cholesterol in the body which is a major risk factor for heart disease. It is important to lower the amounts of trans fats you eat to help you stay healthy.
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.
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.
Saturated fat. This is a type of fat that comes mainly from animal sources of food, such as red meat, poultry and full-fat dairy products. Saturated fat raises total blood cholesterol levels and low-density lipoprotein (LDL) cholesterol levels, which can increase your risk of cardiovascular disease. Saturated fat may also increase your risk of type 2 diabetes.
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.
Trans fatty acids are formed when a liquid fat is changed into a solid fat through a process called hydrogenation. Many manufacturers use hydrogenated oils as an ingredient because it extends the shelf life and consistency of foods. Trans fat will raise levels of “bad” LDL cholesterol and decrease levels of “good” HDL cholesterol. There are no safe levels of trans fat to eat each day, so try to avoid trans fat completely. Even if a food is advertised as “trans fat free,” it can still contain small amounts of trans fat. Therefore, avoid foods that list partially hydrogenated oils as ingredients. Sources of trans fat include:
Often thought of as a high-fat food, steak is actually not as high in fat as you may think, particularly if you choose one of these lean cuts, which have 5 grams of fat and less than 2 grams of saturated fat per 3-ounce serving, on average. What's more, lean beef is an excellent source of protein, iron, and zinc, all important nutrients for active women. One 3-ounce portion of lean beef packs a whopping 25 grams of muscle-building protein, three times the iron (which is important for carrying the oxygen in your blood to your brain and muscles) of 1 cup of spinach, and a third of your daily zinc needs to help support your immune system. Lean cuts of pork, like pork tenderloin, can also be a good source of fat when eaten in moderation. Cured and processed pork, like bacon, often contains loads of sodium and other preservatives like nitrates (which have been linked to increased heart disease and cancer risk), so they're not the healthiest way to consume the other white meat.
While all unsaturated fats are good for you, you'll get more benefits from omega-3 fatty acids. These unsaturated fatty acids can't be produced by your body, so you need to get them from your diet. And they're crucial to your well-being, since they promote good cardiovascular health, play a role in brain function and offer anti-inflammatory benefits. They're also great for your cholesterol, since they increase "good" (HDL) cholesterol levels.
Plus, subsequent studies have also found that picking the right types of fat and adding plenty of high-fat foods to your diet could actually bring some big benefits to your health. One study in the New England Journal of Medicine found that when subjects ate either a Mediterranean diet, low-fat diet or low-carb diet, those following a high-fat, low-carb meal plan not only lost the most weight but also drastically reduced their bad cholesterol levels.

If you’re able to tolerate dairy, full-fat dairy can be an excellent source of heart-healthy fats. Probiotic yogurt, in particular, is a staple on the healthy fats list as it contains beneficial bacteria that can help optimize the health of your gut microbiome to promote better overall health. Upping your intake of probiotics can also support healthy digestion, boost immunity and reduce cholesterol levels. (29)
