Trans Fats: Demons in the Diet

New Labels Are Now in Place

Trans fats, unhealthy man-made fats, are lurking in almost every box and package in your cupboard. These fats have no redeeming qualities and account for 30,000 to 100,000 deaths every year. Among their negatives: trans fats increase your risk of cardiovascular disease (CVD), one of the leading causes of death in the United States. The National Heart, Lung, and Blood Institute (NHBLI) states more than 12.5 million American men and women have CVD, and more than 500,000 die of it each year.

How Did Trans Fats Use Start?

Some trans fats occur naturally and do not pose the same health risks as their man-made relatives engineered in the laboratory. Manufactured trans fats originate as liquid vegetable oils such as soybean and cottonseed oils, then are bombarded with hydrogen atoms in a process known as partial hydrogenation. The end result: a stiffer, more stable fat.

In the early 1900s these engineered fats were developed as a healthier alternative to saturated and animal fats. The biggest transition to trans fats was the switch from butter to margarine, but now we know margarines are actually no more healthful than butter. In fact, recent research reveals trans fats lower HDL, the “good” cholesterol, and raise total cholesterol almost twice as much as saturated fats do.

The University of Maryland Medical Center reports humans have no need for these man-made fats. Instead, food manufacturers started putting them in products because they allow for a longer shelf life. Crackers, for example, can stay crispy and on the shelf for years in part because of the hydrogenated fats in them—and there is really no way of knowing how long that box (or any other) has been on the shelf.

As early as five years ago, researchers were finding proof that trans fats are connected to heart disease. It’s only as of this year the Food and Drug Administration (FDA) started requiring manufacturers of prepared foods to make labeling changes. As of January 1st, they must list the amount of trans fat in foods on the package’s Nutrition Facts panel on a separate line, just as they have been required to provide saturated fats and dietary cholesterol levels since 1993.

Trans fat does not have to be listed if the total fat in a food is less than 0.5 gram (or 1/2 gram) per serving and if no claims are made about fat, fatty acids, or cholesterol content. If it is not listed, a footnote will be added stating that the food is “not a significant source of trans fat.”

Label-Reading Advice

As of this writing, a temporary reprieve has been granted to some manufacturers for the designation of trans fats on the nutrition facts label. You cannot always read in actual numbers how much of this fat is in the products you buy. So read ingredient labels and instead of seeking the words ‘trans fat,’ look for ‘partially hydrogenated oil’ or ‘hydrogenated oil.’

Remember the ingredients listed on the food’s package are given in descending order, according to weight. That means the heaviest ingredient is first, and the lightest is last. If you are having a difficult time finding foods processed without the addition of partially hydrogenated oils, you can at least cut down on the amount of these fats in your diet by selecting foods that list theseoils toward the end of ingredients. Another option is organic foods. They tend to use fats that are more healthful, and they do not contain trans fats.
