Fat intake and polyunsaturated fats -

The body uses fatty acids to make the fats that it needs. Fats are important for how your body uses many vitamins.

And fats play a role in how all cells in the body are made and work. But all dietary fats are not the same. They have different effects on the body.

Some dietary fats are essential. Some increase the risk for disease, and some help prevent disease. Find out how different dietary fats affect your body and how to choose foods with healthier fats.

There are two main kinds of dietary fats: saturated fat and unsaturated fat. These terms describe the chemical makeup of the fatty acids. Most foods have a mix of different kinds of fat. But some have higher levels of saturated fats, and others have higher levels of unsaturated fats.

Key differences in fats include the following:. Saturated fats can add up quickly in foods that combine ingredients. diets, the most common sources of saturated fats are sandwiches, burgers, tacos and burritos — foods that usually combine meat and dairy products.

Baked goods with butter, full-fat ice cream and other desserts are also common sources of saturated fats. Saturated fat tends to raise levels of cholesterol in the blood. Low-density lipoprotein LDL is called "bad" cholesterol.

High-density lipoprotein HDL is called "good" cholesterol. Saturated fats raise the levels of both. A high level of bad cholesterol in the bloodstream increases the risk heart and blood vessel disease. Limited evidence suggest that saturated fats and high cholesterol levels may be linked to an increased risk of Alzheimer's disease or other diseases that cause dementia.

Monounsaturated fats are found in many foods, including red meats and dairy products. About half the fats in these foods are saturated and half monounsaturated. Many plants and plant oils are high in monounsaturated fats but low in saturated fats. These include:. Monounsaturated fats from plants may lower bad cholesterol and raise good cholesterol.

They also may improve the control of blood sugar levels. Replacing saturated fats with monounsaturated fats in the diet may lower the level of bad cholesterol and triglycerides in the blood.

A high level of triglycerides in the blood increases the risk of diseases of the heart and blood vessels.

Eating plant foods high in monounsaturated fats, particularly extra virgin olive oil and tree nuts, may benefit heart health and blood sugar regulation.

Benefits of a diet high in omega-6 fatty acids, especially when they replace saturated fats, may be linked to:. Trans fats are a type of fat that raises bad cholesterol and lowers good cholesterol.

There are very small amounts of naturally occurring trans fat in meats and dairy from grazing animals, such as cows, sheep and goats. But most trans fats are in plant oils that have been chemically changed to be a solid fat.

These are called partially hydrogenated oils. At one time, trans fat oils were thought to be a healthy choice to replace saturated fats.

They also were inexpensive and a had a long shelf life. The U. Food and Drug Administration determined that artificially created trans fats are "no longer recognized as safe" in foods.

They are no longer used in U. food production. They may still be used in other countries. A healthy diet is a balance between taking in enough calories and nutrients for your level of activity. Your health care provider or a dietician can help you understand goals for calories, nutrients and types of foods to eat.

One thing to consider is that each gram of fat has 9 calories. That's true for all fats. So calories can add up quickly, even with healthy fats.

For example, walnuts are a healthy snack high in polyunsaturated fats. But just a dozen walnut halves contain about calories — more calories than in one large apple. The key message about fats is to focus on eating healthy fats and limiting unhealthy fats.

Eat more fruits, vegetables, legumes, nuts, seeds and whole grains that are rich in vitamins, nutrients and fiber. There is a problem with information submitted for this request.

Even though the unsaturated fats are heart-healthy fats, they still contain 9 calories per gram, so serving sizes of healthy fats must be considered to stay within the daily recommended intake and not exceed daily calorie needs.

Monounsaturated fats can lower the risk of heart disease and stroke by reducing LDL cholesterol levels. It is recommended that, while still staying within the recommended intake range, more mono- and polyunsaturated fats are consumed in place of saturated fats U.

National Library of Medicine a. Food Sources Monounsaturated fat sources include non-tropical plant-based oils, such as olive, canola, peanut, safflower, and sesame oils, as well as avocados, nuts, and seeds.

These oils are usually liquid at room temperature but will start to solidify in cooler, refrigerated temperatures. Polyunsaturated fats can help reduce LDL cholesterol levels, which in turn can lower the risk for heart disease and stroke.

They provide important nutrients that allow the body to run efficiently and properly. Oils rich in polyunsaturated fats also contribute vitamin E to the diet which acts as an antioxidant, helps with blood flow, and repairs body tissues. Polyunsaturated fats include omega-3 and omega-6 fats.

These essential fatty acids are needed for brain function and cell growth. The body does not make essential fatty acids, so they can only come from food or supplements. Omega-3 fatty acids are good for the heart by reducing triglycerides, regulating heart rhythm, slowing the buildup of plaque in arteries, and slightly lowering blood pressure.

Omega-6 fatty acids help control blood sugar, reduce the risk of diabetes, and lower blood pressure U. National Library of Medicine b. Food Sources Vegetable oils, such as safflower, corn, soybean, and sunflower oils; nuts, seeds, tofu, and soybeans; and fish, including salmon, mackerel, herring, albacore tuna, and trout.

are good sources of polyunsaturated fats, as is canola oil, though it is higher in monounsaturated fat. However, they are solid or semi-solid at room temperature due to their high content of short-chain saturated fatty acids. They are considered solid fats for nutritional purposes.
