In England, Asda, Wal-Mart's Supermarket Chain to Remove Artificial Colors, Trans Fats, MSG & Aspartame from Foods that Carry its Name

"Studies show that foods that contain synthetic dyes, such as red dye
40 and yellow dyes 5 or 6, or a preservative, such as BHT, BHA or
TBHQ, can disrupt the attention span or hurt the disposition of some
children for hours or even days. Although these chemicals are still
used in food in this country, studies in England have led Asda, Wal-
Mart's supermarket chain in that country, to begin removing artificial
colors, trans fats, MSG and aspartame from any foods that carry its
name. Three other big chains are doing much the same, and the British
school system is making major changes, too. The government no longer
lets schools serve meals with high amounts of salt and fat; it has
banned chocolate, sodas and low-quality meats and will no longer allow
the schools to sell sweetened drinks or cakes or snacks with added
sugar, salt or fat."
