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.
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 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.
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.
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.
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.
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.
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.
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.

You may wonder isn't fat bad for you, but your body needs some fat from food. It's a major source of energy. It helps you absorb some vitamins and minerals. Fat is needed to build cell membranes, the vital exterior of each cell, and the sheaths surrounding nerves. It is essential for blood clotting, muscle movement, and inflammation. For long-term health, some fats are better than others. Good fats include monounsaturated and polyunsaturated fats. Bad ones include industrial-made trans fats. Saturated fats fall somewhere in the middle.
Investigators looked at the relationship between saturated fat intake and coronary heart disease (CHD), stroke, and cardiovascular disease (CVD). Their controversial conclusion: “There is insufficient evidence from prospective epidemiologic studies to conclude that dietary saturated fat is associated with an increased risk of CHD, stroke, or CVD.”(13)
Saturated fats are generally solid or waxy at room temperature and come mostly from animal products, with the exception of tropical oils. Taking in too much saturated fat is linked with raising levels of “bad” LDL cholesterol in the blood and increasing internal inflammation. Healthy adults should limit their saturated fat intake to no more than 10% of total calories. For a person eating a 2000 calorie diet, this would be 22 grams of saturated fat or less per day. If you have elevated LDL cholesterol levels, it is recommended to reduce saturated fat intake to no more than 7% of total calories. Foods high in saturated fat include:
A fascinating Swedish study found that when diabetics ate a low-carb, high-fat diet (50 percent fat, 20 percent low-glycemic carbs, and 30 percent protein) they lost equal amounts of fat after 6 months (4 kg) as a group that ate a low-fat, high-carb diet (30 percent fat, 60 percent carbs, and 10 percent protein). The low-carb, high-fat group decreased insulin and had better blood sugar regulation than the high-carb group, indicating better metabolic chemistry.
Healthy fats can reduce the risk factors for heart disease, especially if you are trying to replace ‘bad’ saturated fat. Many studies have found that a high intake of monounsaturated fats can reduce levels of blood cholesterol and triglycerides (11, 12). Other smaller studies have found that monounsaturated fats can reduce ‘bad’ LDL cholesterol and increase the amounts of ‘good’ HDL cholesterol (13).
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.
Since sources of fat are more calorie-dense, it is important to understand what a serving of a fat is equivalent to. For example, one teaspoon of butter, margarine or mayonnaise is one fat serving. For times when you may not have a measuring spoon available, a visual equivalent of one teaspoon is the tip of your thumb. See below for examples of serving sizes for added fats.
Many people also wonder: is cheese bad for you? Like other dairy products, not all cheese is created equal, but it can be part of a nutritious, well-rounded diet. Ideally, look for varieties that are raw, minimally processed and derived from grass-fed animals. Feta, goat, ricotta and cottage cheese are a few of the top healthiest cheese options available.
Nine moderately athletic men took either spirulina capsules or a placebo for four weeks in a study printed in Medicine & Science in Sports & Exercise. Afterward, the men who had taken spirulina supplements were able to run 30 percent longer than the men who had taken a placebo and burned 11% more fat during a run! Fueling up before your run?

Just like when selecting healthy sources of fat to include in your diet over fried foods and processed junk, opting for nutrient-dense carbohydrates is key. Go for healthy, gluten-free grains like quinoa, amaranth, brown rice and oats. Include a good variety of fruits, vegetables and legumes in your diet. Limit your intake of heavily processed and refined carbs to help improve the quality of your diet.
Little pumpkin seeds, sunflower seeds, and sesame seeds pack a big punch. They have "good" fats that can lower cholesterol. In general, fats that come from plants are healthier than those from animal products. "Bad" fats are in foods like fatty cuts of meat, full-fat dairy products, and some packaged foods. Check food labels to see how much fat, and what type, you're getting. Limit saturated fats and avoid trans fats.
Some forms of saturated fats, such as coconut oil, are comprised of medium-chain fatty acids, which are easier to metabolize than the long-chain fatty acids found in animal fats. This makes coconut oil much healthier for you. In fact, coconut oil has a whole host of other good properties, including lauric acid which is antiviral and antibacterial, and caprylic acid which is antifungal.
Although fat got a lot of flak in the carb-crazy ‘90s, fat is actually very important to a healthy diet. Fat comes in two main forms: unsaturated and saturated fat. Unsaturated fats are oils — the kind that are fluid at room temperature (such as olive and canola oils). Saturated fats are solid at room temperature (think a stick of butter or glob of coconut oil).
All fats and oils contain fatty acids. You may be most familiar with Omega 3 fatty acids, found in fish oil. When you eat healthy fats and oils, the digestion process enables the fatty acids to be absorbed into the blood. Fatty acids are a component of fats and oils that become the building blocks of your body, helping to create cells membranes and nerve sheathing among other body functions.
