The Claim

Consumption of two ounce-equivalent portions of black beans and sliced almonds results in equivalent postprandial essential amino acid bioavailability in humans.

In plain English

Eating two ounces of black beans provides the same amount of essential amino acids in the bloodstream after eating as eating two ounces of sliced almonds.

See the scientific wording

Black beans and sliced almonds provide equivalent postprandial essential amino acid bioavailability when consumed in two ounce-equivalent portions, indicating that not all plant-based protein sources differ in amino acid availability and that some plant proteins may be nutritionally comparable in this specific context.

Why this might work

When black beans or sliced almonds are eaten, digestive enzymes break down their proteins into individual essential amino acids, which are absorbed through the gut wall into the bloodstream. The amount of each amino acid released depends on the protein structure and composition of the food. Once in the blood, the concentration of these amino acids rises and stays elevated for a period, and this rise is similar between the two foods when eaten in equal portions.

    The study directly compared black beans and almonds using the same methodology and found no statistically significant difference in EAA iAUCpos, indicating that within the plant-based group, these two foods deliver similar amino acid bioavailability under acute feeding conditions.
