The Claim

In middle-to-older aged adults, supplementing a low-protein breakfast with whey protein or pea protein has no significant effect on perceived taste preferences for sweet, salty, or savory foods, but pea protein supplementation is associated with a higher desire for fatty foods compared to whey protein supplementation.

In plain English

In middle-to-older adults, adding pea protein to a low-protein breakfast increases the desire for fatty foods compared to adding whey protein, but neither protein supplement changes how much people prefer sweet, salty, or savory flavors.

See the scientific wording

In middle-to-older aged adults, supplementing a low-protein breakfast with whey or pea protein does not significantly alter perceived taste preferences for sweet, salty, or savory foods, but may increase desire for fatty foods with pea protein compared to whey.

Why this might work

When pea protein is eaten, it releases amino acids more slowly than whey protein, which changes signals from the gut to the brain. These signals make the brain want more fatty foods, but do not change how much the person wants sweet, salty, or savory foods.

  1. Study: Postprandial plasma amino acid and appetite responses to a low protein breakfast supplemented with whey or pea protein in middle-to-older aged adults

    The study found no differences in sweet, salty, or savory cravings but identified a statistically significant increase in fatty food desire with pea protein at multiple timepoints, indicating a specific, minor effect on one taste preference.
