An article by Denise Mann, updated July 6, 2006, quotes ACSH's Dr. Ruth Kava on trans fats:
"We used to use animal fats, and people said, 'saturated fats are bad,' so we switched to trans fats," says Ruth Kava, PhD, RD, director of nutrition at the New York City-based American Council on Science and Health. "This kind of gives us an unfortunate focus on ingredients rather than the whole diet when the problem isn't this fat or that fat, it's too many calories"...
Kava adds: "The most important thing is looking at the number of calories and then serving size. Then check out saturated fat and trans fat on the label. It might help some people make smarter decisions."
