Abstract

In vivo studies of almond digestibility. For solid food particles, digestion is a surface phenomenon because enzymes and surface active agents may not be able to penetrate; thus, in the jejunum where the concentration of enzymes is not limiting the rate of digestion will be a function of particle size (surface area). If total digestion and extraction of nutrients is not complete during the passage of the food through the small intestine (1-6h) then the nutrients are `lost¿ to the colonic biota or faeces. The extent of any `loss¿ has not been quantified and the bland assumption that chemical composition is equal to nutrients absorbed continues to hold sway. With the growing popularity of nuts in cereal bars, breakfast cereals and as an addition to healthy diets it is now essential to determine how much of the nutritional potential is realised and how much lost. Study design: This is a pilot study in ileostomy volunteers based on a mass balance of almond ingested and recovered from ileal effluent. The study is designed to determine the extent to which almond fragments survive passage through the stomach and ileum. The undigested almond residue will be separated form the ileal effluent and the residual lipid and vitamin E content assayed.
