The study comprises one arm of 12 healthy Jamaican male and female adults with normal body mass inex, aged 20 to 45 years, receiving a test meal containing the common bean that was intrinsically labelled with deuterium .

Nutrition Deficiency Due to A Particular Kind of Food

The intervention comprises a test meal of intrinsically deuterium labelled stewed common bean with rice. The meal is mixed with a reference protein (Universally labelled 13C-spirulina, 12 mg/kg) and 13C6-Phenylalanine (0.05mg/kg) which is divided into equal mini meals and fed hourly over 8 hours. Protein in the total meal provides 15% of the energy intake with the labelled bean contributing >50% of the protein.

Quality of Protein From the Common Bean

Bioavailability of Essential Amino Acids From the Common Bean (Phaseolus Vulgaris) in Young Healthy Jamaican Adults Consuming a Typical Meal

Measured by comparing plasma enrichment of each deuterium labelled indispensable amino acid (IAA) from the bean to plasma enrichment of the same 13C- labelled IAA from a highly digestible reference protein (Universally 13C-labelled spirulina)

Calculated based on the enrichment of free L-[ring-13C6]-phenylalanine in plasma at steady state divided by its enrichment in the meal.

The model is based on the concept that if amino acids in protein become labelled with an isotopic tracer within the food matrix, their appearance in the blood gives a measure of their bioavailability following digestion and absorption of the protein; which is independent of other proteins in the food and independent of endogenous body proteins and gut bacterial proteins. Amino acids in the common bean were labelled with deuterium, by adding a bolus dose of deuterium oxide (2H2O) to the irrigation water. Then a dual tracer technique is used to measure the bioavailability of amino acids in the bean. After consuming a diet prepared with the mature bean, comparative tracer appearance in blood of the deuterium labelled amino acids from the bean and amino acids derived from a reference protein labelled within another tracer (U-13C- spirulina) gives a direct measure of bioavailability of the bean amino acids.

After 2 weeks of run-in period, subjects take 2 Omnia pills per meal (3 meals a day) for 12 weeks.
