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.
One way to combat inflammation is to eat more Omega 3s to help balance the ratio. But you can also look at your intake of omega 6s and try to cut back on those as well. Beef that is fed corn or grains is high in omega 6s (conversely grass-fed beef is high in omega 3s.) Safflower, sunflower corn, and cottonseed oils are all high in omega 6s. (Read labels for chips, crackers, cookies, and other processed foods, which often contain these oils.) Soybeans and corn are also high in omega 6s. Cutting back on processed foods and eating more cold water, high-fat fish can help get this ratio back in balance.
Polyunsaturated fats are required for some of the normal body functions listed above, but the body can’t produce them so they must be obtained from foods. Omega 3 fatty acids are a type of polyunsaturated fat and can be found in cold-water high-fat fish like salmon, mackerel, and sardines, and in flaxseeds, chia seeds, walnuts, canola oil (again look for non-GMO or organic), and unhydrogenated soybean oil (also look for non-GMO or organic as most soy products in the US are GMO unless they specifically state non-GMO or organic.) Omega 3’s are also found in some greens, including romaine, spinach, and arugula. Note that the body only partially converts plant-based omega 3’s to DHA and EPA, which are found in cold-water fish
Several studies explore and show the this type of saturated fat in coconut does not negatively affect cholesterol levels nor overall heart health like we were once told. Some studies have shown coconut oil moderately increases metabolic rate, which is often a “selling” point that it helps boost your metabolism and contribute to fat loss or weight control. I’ll let these studies here, here, and here tell you what we do know.
This Mediterranean oil is rich in cancer-fighting polyphenols and heart-strengthening monounsaturated fats, including oleic acid. This fat’s help in getting you lean is backed by some pretty strong facts: A recent study from Obesity found that an olive-oil-rich diet resulted in higher levels of adiponectin than did a high-carb or high-protein diet. Adiponectin is a hormone responsible for breaking down fats in the body, and the more you have of it, the lower your BMI tends to be. Another reason for you to use this lipid in your dressings and sauces: extra virgin olive oil may increase blood levels of serotonin, a hormone associated with satiety.
Meanwhile, the official unsaturated fat definition encompasses any type of fatty acid that contains at least one double bond within the chain. These fats are further classified as either a monounsaturated fat or polyunsaturated fat based on the number of double bonds they contain. Unsaturated fats can include foods like vegetable oils, nuts, seeds and fish.
Of the three macronutrients, carbohydrates are our body’s preferred energy source because they are easier and quicker for our bodies to digest and use for energy. On the other hand, fat takes a different route before we can use it as energy because it is insoluble in our blood. Think of fat as being a reserve or our long-term source of energy that sticks around the longest. On the technical side, which we’re about to get very technical: fat is three fatty acids + a glycerol molecule, or a triglyceride (tri- as in three and glyceride).
It is true. When looking to lose weight or gain muscle, people often focus on their protein and carbohydrate intakes. But fat can be just as important. Fats help to keep hormone levels balanced which means you can recover more quickly, and more effectively from your physical activities. Play around with what you are eating by adding some healthy fats. What you may see is greater muscle gains and leaner curves.
From time to time, try swapping other meats for a serving of fatty fish that is high in protein and Omega-3s. Popular types of fatty fish include salmon, anchovies, Chilean sea bass, mackerel, and sardines. Those who consumed this type of fish regularly were found to have less of a risk for a heart attack, according to a study in the American Journal of Clinical Nutrition. Warren adds that consuming fatty fish has also been linked to an improved mental ability and may help prevent cancer.
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.
Along with nuts, seeds get high marks as healthy fats to improve good cholesterol. And flaxseeds are especially popular among nutritionists because of their versatility in a heart-healthy diet. “Sprinkle flaxseeds onto whatever you like,” says Haisley. “My favorite is with Greek yogurt or on my oatmeal. It is a great addition to salads or whisked into your favorite homemade salad dressing. You can even bake with it, too; try using 3 tablespoons of flaxseed in place of 1 tablespoon of oil or margarine in your muffins.” Try these cranberry-nut mini loaves with flaxseeds.
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.
Why are trans fats bad for you, polyunsaturated and monounsaturated fats good for you, and saturated fats somewhere in-between? For years, fat was a four-letter word. We were urged to banish it from our diets whenever possible. We switched to low-fat foods. But the shift didn't make us healthier, probably because we cut back on healthy fats as well as harmful ones.
But as you know, not all fats are created equal. Saturated and trans fats are the worst kind, as both increase the amount of bad cholesterol that enters the blood system. Bad fats also lead to inflammation, which can cause numerous debilitating diseases. All of the burgers, French fries, pizza and other greasy junk foods are loaded with these bad fats that can harm your body.
And if you're thinking fish-oil capsules will help you avoid the contamination risks of fresh fish, think again. Because supplements are not regulated in the U.S., Sandon says, some may contain concentrated amounts of the same toxins found in fresh fish. And because the oil is so concentrated, the supplements can also produce an unpleasant body odor.
Leading the charge of the healthy fat brigade are avocados. This wonder fruit is essentially Mother Nature’s butter. It’s rich, creamy, and—unlike butter—an acceptable food to eat all on its own. While you should still limit yourself to a quarter or half of an avocado per meal, you have no reason to fear its fats. Avocados pack in healthy monounsaturated fats that contain oleic acid, which can actually help quiet feelings of hunger, according to a Food Function study. They also give you two things butter doesn’t: protein and fiber.
Polyunsaturated fats can primarily be found in plant-based foods and oils. Similar to monounsaturated fats, polyunsaturated fats can decrease the risk of heart disease by lowering levels of blood cholesterol (9). A certain type of polyunsaturated fat, omega-3 fatty acids have been found to be particularly beneficial for heart health. They not only lower the risk of coronary artery disease but can also lower blood pressure and protect against irregular heartbeats (9). Omega-3 fatty acids can be easily consumed by eating fatty fish such as salmon, sardines and trout.
