What do nutrition experts eat for breakfast? Because September is “breakfast month” — who knew? — Business Insider asked 38 of them what they liked to eat for the meal that is widely regarded as the day’s most important, and why.

Ronald McDonald is going cage-free. McDonald’s Corp has vowed to buy only eggs from cage-free chickens to supply its U.S. and Canadian restaurants, setting a full-transition deadline of 10 years, or by 2025. The move follows McDonald’s recent “all-day breakfast” announcement, as well as cage-free transition promises from Burger King (deadline: 2017), Starbucks, General Mills, Nestle and other companies.
