Abstract
BACKGROUND: Roux-en-Y gastric bypass (RYGB) is among the most performed bariatric surgery techniques. One known complication of RYGB surgery is food intolerance, which may limit the intake of protein. OBJECTIVE: To investigate the relationship of food intolerance after RYGB surgery with masticatory efficiency, chewing time and cycles, and consumption of protein and red meat. METHODS: A case-control study in subjects with and without food intolerance (regurgitation and/or vomiting more than once a week) aged over 18 years old who had undergone RYGB more than 2 years prior, with an absence of no more than 2 dental units and normal oral motor system evaluation. Masticatory efficiency was evaluated by the granulometry of red meat chewed by the study subject according to a predefined protocol using a sieving technique and classified from very poor to excellent. Protein and red meat consumption were evaluated by usual food recall and a 3-day dietary diary. RESULTS: The study population consisted of 24 cases (37.7 ± 7.57 years old, 79.2% females) and 68 controls (38.0 ± 8.75 years old, 61.8% females). There was a statistically significant association (p = 0.001 by the ranksum test) between food intolerance and masticatory efficiency, with 58.3% of cases and 23.5% of controls showing very poor masticatory efficiency. No evidence was found of an association of food intolerance with chewing time, chewing cycles, low protein or red meat consumption. CONCLUSION: Masticatory inefficiency is a contributing factor to food intolerance after RYGB, regardless of time and chewing cycles. No relationship was found between food intolerance and consumption of red meat and protein.
