However, all dietary fat—both unhealthy trans and saturated fats and good-for-you monounsaturated and polyunsaturated fats—is more calorie-dense than protein and carbohydrates, so eating too much could lead to weight gain.
Which fat is considered healthful?
Monounsaturated fats and polyunsaturated fats are known as the “good fats” because they are good for your heart, your cholesterol, and your overall health.
Which fats are good for health?
“Good” unsaturated fats — Monounsaturated and polyunsaturated fats — lower disease risk. Foods high in good fats include vegetable oils (such as olive, canola, sunflower, soy, and corn), nuts, seeds, and fish.
What is the difference between unsaturated fat and saturated fat?
The difference between saturated and unsaturated fat lies in the number of double bonds in the fatty acid chain. Saturated fatty acids lack double bonds between the individual carbon atoms, while in unsaturated fatty acids there is at least one double bond in the fatty acid chain.
What is monounsaturated fat?
Monounsaturated fat is made up of triglycerides in which most of the fatty acids are monounsaturated, meaning they have only one double bond between carbon atoms in each fatty acid carbon chain. An example is olive or canola oil. Polyunsaturated fat.
What is a fat made of?
Fats are made up of fatty acids (which are both saturated and unsaturated) and glycerol. For a fat to be classified as unsaturated, it must contain at least one double bond in the fatty acid carbon chain. This means there are at least two carbon atoms in the fatty acid chain that are not saturated with hydrogen (those forming the double bond).
What are the two types of unsaturated fats?
There are two types of unsaturated fats. The difference between the two is in the chemical structure: 1 Monounsaturated fat. Though liquid at room temperature, monounsaturated fat may solidify when placed in the refrigerator. Monounsaturated fat is made up of triglycerides in which most of the fatty acids are monounsaturated, meaning they have only one double bond between carbon atoms in each fatty acid carbon chain. An example is olive or canola oil. 2 Polyunsaturated fat. It is usually liquid both at room temperature and in the refrigerator. When exposed to oxygen, polyunsaturated fats tend to become rancid more readily than monounsaturated fats. Polyunsaturated fat is made up of triglycerides in which most of the fatty acids are polyunsaturated, meaning they have two or more double bonds between carbon atoms in the fatty acid carbon chain. Sunflower or soybean oil is an example.
Why do polyunsaturated fats need hydrogenation?
Sometimes, monounsaturated and polyunsaturated fats may need to be partially hydrogenated to make them more solid and resistant to spoilage (e.g., margarine, shortening). In this process, hydrogen molecules are added and the number of double bonds is reduced. The fats thus become more saturated.
What does HDL cholesterol do to the body?
HDL cholesterol (HDL stands for high-density lipoprotein) carries cholesterol from the blood back to the liver. The liver then breaks down the cholesterol so that it can be eliminated from the body. This prevents excess cholesterol from being deposited as plaque in the arteries.
What is the purpose of polyunsaturated fatty acids?
Research suggests that these polyunsaturated fatty acids prevent blood platelets from clotting and sticking to artery walls, thus helping to prevent hardening of the arteries, reducing blood pressure levels and helping to protect the body against irregular heartbeats.
Why is it important to consume unsaturated fat?
Despite that, people are urged to consume unsaturated fat in moderation, because excess calories from consuming large amounts of any type of fat can lead to weight gain. Dietary fat intake should not make up more than 35% of a person’s total daily calories.
