Some people choose to be vegetarians because they don't approve of consuming animal products, while others may simply want to avoid foods that have been processed or that may contain hormones.

Either way, consuming a plant-based diet may help improve their digestive health, according to a recent study published on the website of the British Medical Journal.

High fiber intake has long been associated with healthy digestive function, and individuals who avoid meat typically consume more products that are rich in the nutrient.

The researchers followed a group of more than 47,000 individuals over the course of nearly 12 years. The study's results showed that those who consumed the most fiber – many of whom were vegetarians – were the least likely to develop bowel problems.

The investigators said that there may be a number of serious health problems that can be averted through dietary changes and healthy lifestyle modifications. However, they noted that "far more evidence is needed before dietary recommendations can be made to the general public."

According to the National Digestive Diseases Information Clearinghouse, as many as 70 million Americans are affected by poor digestive function.
