"Mars, the one-time maker of king-sized chocolate bars, is considering taking its M&Ms out of sugary dessert treats, including McDonald's McFlurry."

NBC:

Mars is concerned desserts that feature its candies - such as the McFlurry, Burger King's Snickers pie and Dairy Queen's Blizzard - exceed in a single serving the amount of sugar the U.S. government recommends anyone eat in a day, the source said.

That kind of sugar load conflicts with Mars' public stance that sweets are best enjoyed in moderation.
