Artificial sweeteners have been controversial for decades. Several studies have attacked sweeteners, especially aspartame used in diet sodas.

In June, St. Louis-based Panera Bread Co. announced it will eliminate artificial sweeteners, coloring and preservatives from its foods by 2016. Panera nutrition manager Katie Bengston said “taste is the driving factor.”

Bengston said Panera is evaluating everything, including the sodas it sells.

The Food and Drug Administration has a plan in the works that may affect your appetite. It wants to ban partially hydrogenated oils -- the major source of artificial trans fats in the U. S. food supply.

How will that impact St. Louis area bakeries, donut shops and grocery stores?

Like many mom-and-pop donut shops in St. Louis, the Donut Stop in Lemay fries with partially hydrogenated shortening – good for glaze retention, shelf life, and mouth feel.
