Researchers are trying to determine the best course of action regarding the dietary management with a diet low in fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAP diet) for irritable bowel syndrome.

An analysis of different educational programs providing information on the low FODMAP diet will be performed.

Inclusion Criteria:

• Adult subjects (18-75 years) seen in the primary care clinic or in the Gastroenterology clinic at Mayo Clinic Florida, who are diagnosed with IBS by Rome IV criteria

Exclusion Criteria:

• Subjects who have previously tried the low FODMAP diet (whether successful or not)
• Current or recent (less than 4 weeks) opioid use
• Current or recent (less than 10 weeks) rifaximin use
• Inability to speak or read English
• Pregnancy and/or breast-feeding
• Medical or psychological issues that would prevent modifying their diet for 8 weeks.
