The ban is being done in half the country, including SF. By the end of the year, Starbucks hopes to be totally fat free around the country. Turns out, Starbucks has been working on getting rid of trans fat for the past two years and are finally ready to do it. This move was made to get ahead of New York's trans fat ban and in response to a potential lawsuit by consumer groups claiming Starbucks is one of the reasons for all the fat asses out there.
There is a chance, however, that it'll make their products even that much more costly as the switch from trans fat products to non-trans fat products can be pricey. Of note is the fact that some of the dairy products contain trans fats and there you have your non-fat decaf late.
As for SFist, we're still half convinced that in another year or so, some study will come out saying that trans fats aren't that bad for you. You wait-- it'll happen.
