How does banning trans fats help us?

In a sweeping nationwide trend, states and major cities--including Philadelphia--are taking steps to ban food providers from using products with trans fats.

 

Eliminating trans fats represents the latest in the fight against heart disease, but it's only one part in addressing the issue.  People still need to monitor their eating habits and activity level, said Angie Makris, an Assistant Professor at Temple's Center for Obesity Research and Education.

 

Also, contrary to popular misconceptions, reducing trans fats in diet doesn't necessarily translate into weight loss.

 

"In the past, much of the focus was on reducing the amount of fat consumed.  Now, the focus is on the type of fat consumed," Makris said.  "Trans fats affect your cardiovascular health, not your caloric intake."

 

As a nutritionist, Makris said the ultimate goal is good health.  This can include losing weight to reduce risk factors for diseases such as heart disease and diabetes, eating nutritious foods, and increasing physical activity.

 

The U.S. Food and Drug Administration mandated that trans fat content be listed on all packaged foods by January 2006.  And then late last year, New York City officials made it the first city to ban trans fat in restaurants.  The ban goes into effect in July.

 

Makris advised following FDA's recommendations when it comes to fat intake:

 

  • Replace saturated and trans fats with mono- and polyunsaturated fats, which do not raise "bad" cholesterol levels and have health benefits when eaten in moderation.  Sources of monounsaturated fats include olive and canola oils.  Sources of polyunsaturated fats include soybean, corn and sunflower oils, and foods like nuts.
  • Eat fish.  Most fish are lower in saturated fat than meat.  Some fish, such as mackerel, sardines and salmon, contain omega-3 fatty acids that are being studied to determine if they offer protection against heart disease.
  • Limit foods high in cholesterol like egg yolks and full-fat dairy products like whole milk.

Makris said she expects the issue of trans fats to stay in the news as more cities seek to ban their use and the FDA continues to modify its food labeling procedures.  Currently, trans fat levels of less than 0.5 grams per 14-gram serving can be labeled as 0 grams of trans fat; therefore, some products containing partially hydrogenated fat and claiming that they do not contain any trans fats may indeed have small amounts of trans fats, according to FDA regulations.

 

The FDA plans to develop consumer education materials about trans fat and make improvements to the nutrition label in order to enhance consumers' understanding about trans fat and nutrient content claims, Makris said.

 

"It's a step in the right direction, but there's a lot more to [good health] than trans fats," Makris said.
