The Claim

Age does not significantly influence postprandial essential amino acid bioavailability following consumption of two ounce-equivalent portions of pork, eggs, black beans, or almonds in healthy adults.

Description
1 study reviewed
In plain English

In healthy older adults, the absorption and use of essential amino acids from pork, eggs, black beans, or almonds after eating are not different from those in younger adults.

See the scientific wording

Age does not significantly influence postprandial essential amino acid bioavailability following consumption of two ounce-equivalent portions of pork, eggs, black beans, or almonds, suggesting that the ability to absorb and utilize dietary amino acids from these protein sources remains intact in healthy older adults.

Why this might work

When food is digested, essential amino acids are released and absorbed through the gut into the bloodstream. These amino acids travel to tissues where they are used to build and repair proteins. This process works the same way in older adults as it does in younger adults, with no reduction in how much amino acid enters the blood or how effectively it is delivered.

  1. Study: Effects of Consuming Ounce-Equivalent Portions of Animal- vs. Plant-Based Protein Foods, as Defined by the Dietary Guidelines for Americans on Essential Amino Acids Bioavailability in Young and Older Adults: Two Cross-Over Randomized Controlled Trials

    The study found that older adults absorbed the same amount of useful amino acids from pork, eggs, beans, and almonds as younger adults—so aging doesn’t make it harder for the body to use these foods for protein.
