My wife recently has purchased potato salads from Wal-Mart, Aldis, and Woodmans in Appleton, Wisconsin. The potato salad from Woodmans made by Garden Fresh Foods of Milwaukee had a peculiar flavor, my family noted. There was an unpleasant feeling in the throat similar to the irritation that sodium benzoate, a preservative, causes in some fruit punch drinks like Sunny Delight. Sure enough, sodium benzoate was an ingredient in the potato salad. But even more disturbing was the inclusion of alum. Hey, there is no need to dump alum into food. Alum contains aluminum ions, and higher aluminum levels have been found in the brains of Alzheimers patients. No, we don’t know if they are part of the problem or just a symptom, but while that remains unknown, I think we should be deliberately avoiding aluminum in our diet.
