Most Crohn’s patients suffer from some form of malabsorption. This means we must choose protein sources that are easy to digest – which is measured based on bioavailability. Bioavailability is the proportion of the nutrient that is digested, absorbed and metabolized through normal pathways.
Leading in bioavailability, whey protein isolate tops the chart with an index over 100. Although, since most Crohn’s patients have intolerances to dairy due to lack of proper enzymes that means eggs are the most reliable and most efficient protein source for Crohn’s sufferers.
For vegan options, the only protein with proper absorption comparable to chicken, egg and other traditional sources is pea protein isolate.
