It's official. New York City has become the first in the nation to ban the use trans-fats at restaurants. The members of the Board of Health voted unanimously for the ban and heath advocates are already applauding the decision. Restaurants will have until July 2007 to switch to trans-fat free frying oils - meaning that all french fries in the city, as well as other fried foods will have to be trans-fat free by that time - and will have until July 2008 to remove all trans-fats from their food.

Trans-fats, which have been called "chemical abominations" by some health officials, are known to raise bad cholesterol and lower good cholesterol, changes which can contribute to an increased risk of heart disease. According to FDA estimates, "the average American eats 4.7 pounds of trans fats each year" in spite of the reductions that food processors have made with their use. They are favored in the restaurant and food processing industries because they are easy to work with, have a long shelf life and can increase the shelf life of foods that use them.

After New York City officials announced a plan to ban trans fats from restaurants, there has been some debate among scientists as to whether the ban will have a beneficial effect on the population. Virtually all experts agree that trans fats are not good for you, but the question about how bad they are has not actually been answered. Trans fats seem to raise the bad levels of cholesterol and lowering the good, which can increase the risk of heart attack and other heart problems. The problem is that while they do increase the bad, the amount that the good is reduced by is not great, so some scientists don't think that the ban will "save lives," as some of the officials behind the ban suggest.

So, the answer seems to be that banning trans fat might be beneficial. And if they change isn't a radical one in terms of health - although it could be - it certainly won't be bad for people to replace trans fats with fats from other sources. Even saturated fat "is at least a natural constituent of our diets," and not a "chemical abomination," as trans fat is.
