Is Pineapple Low FODMAP?
Yes, pineapple is a low FODMAP fruit and can be safely consumed by patients with IBS in appropriate serving sizes (approximately 80g or one standard portion). 1
FODMAP Classification of Pineapple
Pineapple lacks the problematic fermentable oligosaccharides, disaccharides, monosaccharides, and polyols that trigger gastrointestinal symptoms in IBS patients through increased small intestinal water volume and colonic gas production. 2
Practical Serving Guidelines
- Limit fresh fruit consumption to 3 portions per day (approximately 80g per portion) as part of general dietary advice for IBS management. 1
- Pineapple can be included during the restriction phase of a low FODMAP diet without concern for triggering FODMAP-related symptoms. 2
- Unlike high FODMAP fruits such as apples and pears (which contain excess fructose and sorbitol), pineapple has a favorable carbohydrate profile that does not lead to malabsorption. 1
Context Within IBS Dietary Management
The low FODMAP diet should be implemented as second-line therapy only after first-line general dietary advice has failed, and must be supervised by a registered dietitian with gastrointestinal expertise. 3, 4
Common High FODMAP Fruits to Avoid:
- Apples (excess fructose relative to glucose) 1, 4
- Pears (unfavorable fructose-to-glucose ratios plus sorbitol) 1, 4
Safe Low FODMAP Fruits:
- Pineapple 1
- Citrus fruits (oranges, lemons, limes) in limited quantities 1
- Bananas, strawberries, and melon 3
Evidence Quality
The low FODMAP diet demonstrates the strongest evidence base of any dietary intervention for IBS, with 52-86% of patients reporting significant symptom improvement and meta-analyses showing reduced risk of remaining symptomatic (RR 0.71; 95% CI 0.61 to 0.83). 4, 5 Recent blinded reintroduction studies confirm that fructans (56%) and mannitol (54%) are the most prevalent FODMAP triggers, not the natural sugars found in pineapple. 6
Clinical Pitfall to Avoid
Do not unnecessarily restrict low FODMAP foods like pineapple during the elimination phase, as overly restrictive eating can lead to nutritional deficiencies, reduced dietary variety, and negative impacts on quality of life. 2 The goal is to eliminate only high FODMAP triggers while maintaining adequate nutrition and food enjoyment.
