Issues with Trans Fats

Issues With Trans Fats
The Dietary Guidelines for Americans 2010 and the Institute of Medicine recommend that individuals keep trans fatty acid consumption as low as possible.1, 2 There are two main sources of dietary trans fatty acids (trans fat). Naturally occurring trans fat is found in small amounts in the fatty parts of meat and dairy products. Artificial trans fat comes from foods that contain partially hydrogenated oil and is formed when hydrogen is added to liquid oil turning it into solid fat. Often food manufacturers use artificial trans fat in food products because it is inexpensive and it increases the food’s shelf life, stability, and texture.

Consuming trans fat increases low-density lipoprotein (LDL, or "bad") cholesterol. This risk factor contributes to the leading cause of death in the U.S. – coronary heart disease (CHD).1 Trans fat may also have other adverse health effects like decreasing high-density lipoprotein (HDL, or "good") cholesterol. Further reducing trans fat consumption by avoiding artificial trans fat could prevent 10,000-20,000 heart attacks and 3,000-7,000 coronary heart disease deaths each year in the U.S.3

Trans fat intake has significantly decreased in the US as a result of efforts to increase awareness of its health effects, Nutrition Facts label changes, industry efforts to voluntarily reformulate foods, and some state and local governments’ restriction of its use in restaurants and other food service outlets. However, on average Americans still consume 1.3 grams (0.6% of energy) of artificial trans fat each day.4 Major contributors to artificial trans fat intake include fried items, savory snacks (like microwave popcorn), frozen pizzas, cake, cookies, pie, margarines and spreads, ready-to-use frosting, and coffee creamers. The amount of trans fat can vary among similar food categories.

The amount of trans fat can vary within food categories4

Food category
Range of trans fat per serving (g)
Margarine and spreads
0.0-3.0 g
0.0-3.5 g
Frozen pies
0.0-4.5 g
Frozen pizza
0.0-5.0 g
Savory Snacks
0.0-7.0 g

 Trans fat are also found in restaurant and cafeteria foods that contain or are prepared with partially hydrogenated oil. Currently, only about 1 in 5 Americans (20 percent) lives where there are policies that limit the use or sale of foods that contain more than 0.5 grams of artificial trans fat per serving.5

What Can Be Done To Rduce Artificial Trans Fat
Read the Nutrition Facts label and ingredient list to compare foods.
o   Choose products with 0 grams trans fat.
o   Check the Ingredient List to see if there is any partially hydrogenated oil in the product.
o   Because products containing less than 0.5 grams of trans fat per serving can be labeled as having 0 grams trans fat, checking the Ingredient List is important to avoid all artificial trans fat.
·         When choosing foods low in trans fat, make sure they are also low in saturated fat and cholesterol: look for foods with 5% of the Daily Value or less. Foods with 20% or more of the Daily Value of these two components are high.
·         Use monounsaturated fat (canola and olive oil) and polyunsaturated fat (soybean, corn, and sunflower oil) in recipes that call for fat.
·         A good way to avoid trans fat is to eat a balanced diet rich in fruits, vegetables, whole grains, lean sources of protein, and low-fat or fat-free dairy products.
·         Ask your grocer to stock products free of “partially hydrogenated oil” and “shortening”.
·         Talk with your favorite restaurant establishment about current use of partially hydrogenated oils or changing to a menu that is 100% free of “partially hydrogenated oil” and “shortening”.
·         Choose restaurants that do not use partially hydrogenated oil to prepare food.
