What are Fats? The Real Skinny on Healthy Fats and Harmful Fats

Chemical Economics Handbook

Oils and fats form an important part of a healthy diet. Structurally they are esters of glycerol with three fatty acids called either triacylglycerols or triglycerides.

The general consensus between dietitians, nutritionists, and other experts is that saturated fat is less healthful than unsaturated fat. However, the overall health impact of saturated fat remains controversial. Some researchers believe it may increase the risk of heart disease, while others believe moderate amounts might benefit overall health.

Fat is also known as lipid and is mainly present in food in a form called 'triglycerides'. Butter and margarine, for example, are almost entirely made up of triglycerides. Triglycerides consist of glycerol and three 'tri' fatty acids. The fatty acids can be mainly 'saturated' as in butter or mainly 'polyunsaturated' as in some margarines see Figure There are also monounsaturated fatty acids, which occur in quantity in the triglyceride of olive oil and peanut oil. Food may contain other fats, such as cholesterol and phospholipids, in addition to triglycerides.

Fats and oils are the most abundant lipids in nature. They provide energy for living organisms, insulate body organs, and transport fat-soluble vitamins through the blood. Fats and oils are called triglycerides or triacylcylgerols because they are esters composed of three fatty acid units joined to glycerol , a trihydroxy alcohol:. If all three OH groups on the glycerol molecule are esterified with the same fatty acid, the resulting ester is called a simple triglyceride. Although simple triglycerides have been synthesized in the laboratory, they rarely occur in nature. Instead, a typical triglyceride obtained from naturally occurring fats and oils contains two or three different fatty acid components and is thus termed a mixed triglyceride.

Though too much fat can be unhealthy, certain kinds of fat are good for us and are an important part of a healthy diet. Fats are nutrients in food that the body uses to build nerve tissue including the brain and nerves and hormones. The body also uses fat as fuel. If fats eaten aren't burned as energy or used as building blocks, they're stored by the body in fat cells. This is the body's way of thinking ahead: By saving fat for future use, it plans for times when food might be scarce. Fat gives food flavor and texture, but it's also high in calories and excess amounts of fatty foods can cause many health problems.
