The Claim

Buttermilk exhibits phytase enzyme activity of 2.93 U/mL in vitro, and this activity is associated with the breakdown of phytic acid during digestion, leading to increased mineral solubility in green gram.

Source: Enhancement of iron, zinc, and calcium bioaccessibility and bioavailability in green gram (Vigna radiata L.) supplemented with buttermilk through phytate reduction: an in vitro dietary evaluation

How it works
1 study reviewed
In plain English

Buttermilk contains an enzyme that breaks down phytic acid in green gram during digestion, resulting in higher availability of minerals.

See the scientific wording

Buttermilk demonstrated measurable phytase enzyme activity of 2.93 U/mL in vitro, suggesting it may contribute to phytic acid breakdown during digestion, which could explain its role in enhancing mineral solubility in green gram.

Why this might work

Buttermilk contains an enzyme that breaks down a compound in green gram that traps minerals like iron, calcium, and zinc. When this compound is broken down, the minerals are freed and stay dissolved in the gut, allowing them to be absorbed into the bloodstream. Acidic substances in buttermilk also help keep these minerals dissolved so they can be taken up by the gut lining.

  1. Study: Enhancement of iron, zinc, and calcium bioaccessibility and bioavailability in green gram (Vigna radiata L.) supplemented with buttermilk through phytate reduction: an in vitro dietary evaluation

    Buttermilk has an enzyme that breaks down a compound in green gram that blocks mineral absorption. The study showed that when buttermilk is added, more iron, calcium, and zinc become available for the body to use.
