New Food Labels Spark Healthy Tweets

Americans eat more these days. And so serving sizes are catching up with their bigger appetites.

Today, the Food and Drug Administration put forth proposed official serving size changes. First lady Michelle Obama was a part of the announcement as it came on the fourth anniversary of her "Let's Move" initiative.

"We have a right to understand what's in the food we're feeding our families," Mrs. Obama said at the White House.

There's no timetable for the changes to take effect, which will be phased in gradually. A 90-day public comment period opens Thursday.

"By law, the label information on serving sizes must be based on what people actually eat, not on what they 'should' be eating," the Food and Drug Administration said in a statement.

In the Philadelphia region, people took to Twitter and Instagram to share their health and nutrition advice. Below is a snapshot.
