The sugar content and acidity of energy products can expedite gum inflammation and tooth decay, leading to poor oral health.

Another Win for Gluten

By Matthew Kadey, MS, RD | January 28, 2020 |

People without a gluten-related disorder (for instance, celiac disease or nonceliac gluten sensitivity) did not experience gastrointestinal symptoms like bloating after consuming gluten flour twice daily for 2 weeks, according to a double-blind, randomized controlled study in the journal Gastroenterology.
