Triglycerides make up more than 95% of lipids in the diet
Triglycerides are the most common type of lipid in the human body and make up more than 95% of lipids in the diet. They are commonly found in fried foods, butter, milk, cheese, and some meats. Naturally occurring triacylglycerols are found in many foods, including avocados, olives, corn, and nuts.
Triglycerides are important because they give us energy. The lipids we consume in our diet can be saturated or unsaturated fats. Saturated fats are solid at room temperature and are typically derived from animal products such as meat, butter, and cheese. Unsaturated fats are usually liquid at room temperature and are often, but not always, derived from plants.
Triglycerides consist of three fatty acids attached to a backbone of glycerol (an alcohol). Fatty acids are essentially hydrocarbon chains with a carboxylic acid group (COOH) at one end, the alpha (α) end, and a methyl group (CH3) at the other, omega (ω), end. They are classified as saturated or unsaturated according to their chemical structure.
Phospholipids make up the outer layer of cells in the bodies of animals and humans. They create a protective layer around the cells. Most people do not have to worry about phospholipids. However, they can cause problems for people with a rare autoimmune disorder called antiphospholipid syndrome (APS). APS often happens in people with lupus—especially women.
Dietary lipids are primarily oils (liquid) and fats (solid). Commonly consumed oils are canola, corn, olive, peanut, safflower, soy, and sunflower oil. Foods rich in oils include salad dressing, olives, avocados, peanut butter, nuts, seeds, and some fish. Fats are found in animal meat, dairy products, and cocoa butter.

Phospholipids are water-soluble and found in both plants and animals
The three main types of lipids are triacylglycerols (also known as triglycerides), phospholipids, and sterols. Triglycerides make up more than 95 percent of lipids in the diet and are commonly found in fried foods, butter, milk, cheese, and some meats. Phospholipids make up only about 2 percent of dietary lipids. They are water-soluble and are found in both plants and animals.
Phospholipids are important because they create a protective layer around the cells in the bodies of animals and humans. They make up the outer layer of cells and cause problems for people with a rare autoimmune disorder called antiphospholipid syndrome (APS). APS often happens in people with lupus—especially women. A common name for APS is "sticky blood". That's a good description of what happens inside the body when these key lipids cannot do their jobs. In people with APS, the proteins on phospholipids get attacked, and the protective layers are damaged.

Saturated fats are solid at room temperature and derived from animal products
Saturated fats are solid at room temperature and are typically derived from animal products such as meat, butter, and cheese. They are one of the three main types of lipids in the human diet, along with phospholipids and sterols. Triglycerides, which are also known as triacylglycerols, make up more than 95 percent of lipids in the diet and are commonly found in fried foods, butter, milk, cheese, and some meats.

Unsaturated fats are liquid at room temperature and often derived from plants
Triglycerides are the most common type of lipid in our body and come from fats and oils in our diet. Triglycerides are important because they give us energy. The lipids we consume in our diet can be saturated or unsaturated fats. Saturated fats are solid at room temperature and are typically derived from animal products such as meat, butter, and cheese. Unsaturated fats are usually liquid at room temperature and are often, but not always, derived from plants. While "lipids" and "fat" are sometimes used interchangeably, fat (a.k.a. fatty acids) is only one type of lipid. Unsaturated fats have essential nutrients commonly known as omega-3 fatty acids and are found in foods like tuna, salmon, nuts, seeds, avocados, and leafy vegetables.
Unsaturated fats are liquid at room temperature and are often, but not always, derived from plants. Monounsaturated fats help regulate blood cholesterol levels, thereby reducing the risk of heart disease and stroke. Both monounsaturated fats and polyunsaturated fats provide nutrition that is essential for normal cell development and healthy skin.
