An increasing number of U.S. consumers are adopting a gluten-free diet, the Los Angeles Times reported Monday. 

People with celiac disease are required to avoid gluten, while others believe the diet boosts energy and improves digestion.

The story noted that sales of gluten-free products increased 20% — from $1.46 billion to $1.75 billion — during the 12-month period ending June 14, according to Nielsen.
