A new study has raised questions about the amount of protein people really need. Protein has become increasingly common in various food and drink products in recent years. The study's findings suggest that the current prevalence of protein in many everyday items may be more than what is necessary.

Further details about the study and its conclusions are available from the Waco Tribune-Herald. For those interested in learning more about the study's results and what they might mean for daily diets, additional information can be found in the original report.
