Worksheet 5-3: Check Your Lipid Choices
Fats give foods their flavor, texture, and palatability. Unfortunately, these same characteristics
entice people to eat too much from time to time. Do you know how to select low-fat foods that
will help you meet dietary fat recommendations? Look at these examples of foods and consider
how often you select the item that is lower in fat.
Which of these pairs are you most likely to select:
Peanuts or pretzels?
Hot dog or turkey sandwich?
The second item in each pair is lower in fat and making such fat-free or lower-fat food choices
regularly can help you meet dietary fat recommendations. In addition, eating plenty of whole-
grain products, fresh vegetables, legumes, and fruits daily will help to keep your fat intake under
control.

Handout 5-1: Chemical Structures of Acetic Acid and a Bile Acid
Acetic Acid – Acetic acid is a two-carbon organic acid.
A Bile Acid – This is one of several bile acids the liver makes from cholesterol. It is then bound to an
amino acid to improve its ability to form spherical complexes of emulsified fat (micelles). Most bile acids
occur as bile salts, usually in association with sodium, but sometimes with potassium or calcium.

Handout 5-3: Butter and Margarine Labels Compared
Food labels list the kcalories from fat; the quantities and Daily Values for fat, saturated fat, and cholesterol; and the
quantities for trans fat. Information on polyunsaturated and monounsaturated fats is optional. Products that contain
0.5 g or less of trans fat and 0.5 g or less of saturated fat may claim “no trans fat.” Similarly, products that contain 2
mg or less of cholesterol and 2 g or less of saturated fat may claim to be “cholesterol-free.”
If the list of ingredients includes hydrogenated oils, you know the food contains trans fat. Chapter 2 explained that
foods list their ingredients in descending order of predominance by weight. As you can see from this example, the
closer “partially hydrogenated oils” is to the beginning of the ingredients list, the more trans fats the product
