What You Need to Know
Trans Fat at-a-Glance
There are two sources of trans fat, also known as trans fatty acids:
• Trans fat formed naturally – this type of trans fat is produced in the
gut of some grazing animals. That’s why small quantities of trans fat
can be found in animal products like milk, milk products, and meat.
• Trans fat formed during food processing – this type of trans fat
is created when hydrogen is added to vegetable oil (a process called
hydrogenation) to make it more solid. Partially hydrogenated oils
are used by food manufacturers to improve the texture, shelf life
and flavor stability of foods. About half of the trans fat Americans
consume is formed during food processing and partially hydrogenated
oils are the main source of this type of trans fat in the U.S.
As a consumer, the most important
thing to know about trans fat is that
it raises low-density lipoprotein
(LDL or “bad”) cholesterol. An
elevated LDL blood cholesterol level
increases your risk of developing
heart disease. Heart disease is the
leading killer of both
men and women
in the U.S.
Fats in Your Diet
Limiting trans fats is one component of a healthful
diet that also includes limiting saturated fat and
dietary cholesterol.
Dietary fats are found in both plant and animal foods.
Fat is a major source of energy for the body and aids
in the absorption of vitamins A, D, E and K. Fat is
also important for proper growth, development and
maintenance of good health.
The Dietary Guidelines for Americans notes that
adults should consume no more than approximately
one third of their calories from fat to reduce their
risk of developing chronic diseases (such as heart
disease), while providing for adequate intake of
essential nutrients.
Infants and toddlers up to two years of age have the
highest energy needs per unit of body weight of any
age group. Fats are an important source of calories
and nutrients for these youngsters.
As a food ingredient, fat provides flavor, consistency
and stability – and helps you feel full.

Where’s the Trans Fat?
Trans fat can be found in many of the same foods as saturated fat.
These can include:
• Crackers, cookies, cakes, frozen pies and other baked goods
• Snack foods (such as microwave popcorn)
• Frozen pizza
• Fast food
• Vegetable shortenings and stick margarines
• Coffee creamer
• Refrigerated dough products (such as biscuits and cinnamon rolls)
• Ready-to-use frostings
Choose Your Fats Wisely
Use the Nutrition Facts Label as your tool for reducing trans fat, saturated fat
and cholesterol in your diet – which may help decrease your risk of developing
heart disease!
• Keep trans fat consumption as low as possible by limiting foods that contain trans fats
formed during food processing. Trans fat has no percent Daily Value (%DV), so when
you look at the Nutrition Facts Label, use the amount of grams (g) as your guide.
• Check the Ingredient List on the food package for partially hydrogenated oils. The Nutrition
Facts Label can state 0 grams of trans fat if the food product contains less than 0.5 grams
of trans fat per serving. Thus, if a product contains partially hydrogenated oils then it might
contain small amounts of trans fat even if the label says 0 grams of trans fat.
• Choose foods low in saturated fat and cholesterol for a healthful diet. When comparing foods,
choose the food with the lower %DV of saturated fat and cholesterol. As a quick rule of thumb:
5% DV or less is low and 20% DV or more is high.
• Cook and bake with vegetable oils (liquid or spray) instead of solid fats, like solid shortenings, butter
or lard. Choose oils that are higher in monounsaturated and polyunsaturated fats (e.g., canola oil and
olive oil), and avoid oils that are higher in saturated fats (e.g., coconut, palm and palm kernel oils).
• Switch from stick margarine to soft margarine (liquid, tub, or spray).
• Try baking, steaming, grilling or broiling instead of frying.
• Eat foods that contain healthier fats, such as nuts (e.g., walnuts and almonds), seeds (e.g., sunflower and
pumpkin), olives and avocados.
• Choose low-fat or fat-free dairy products and lean cuts of meat and skinless poultry.
• Eat more seafood and choose it in place of some meat and poultry.
• Get plenty of foods that are naturally low in fat, such as whole grains, fruits and vegetables.
• When eating out, remember to ask which fats are being used in the preparation of the food you’re ordering. You can
also ask to see nutrition information available in many fast food or chain restaurants and choose a lower-fat option.
