Irritable Bowel Syndrome Message Boards | Re: FODMAPs and infusion?

The USDA Food Database lists "Lettuce, cos or romaine, raw" as having 0.39 grams glucose and 0.80 grams fructose for an excess of 0.40 grams of fructose. The Gibson and Shepherd article says "Foods and beverages containing > 0.5 g fructose in excess of glucose per 100 g ..." are considered unsafe. So US grown romaine lettuce should be fine. However, it may give problems due to its high insoluble fiber content.

An important thing to consider is the fact that the values given in food tables are averages usually for foods produced/prepared in a given region. The values can change depending on a several factors ranging from the methodology used to determine them to the growing conditions and plant varieties grown in the region.

The values in food tables are useful guidelines but when in doubt always trust your gut
