The Claim

The addition of phytic acid to a low-zinc diet causes exacerbated zinc deficiency in male rats, as evidenced by depressed zinc status relative to control groups not receiving phytic acid supplementation.

Source: EDTA disodium zinc has superior bioavailability compared to common inorganic or chelated zinc compounds in rats fed a high phytic acid diet.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

When male rats eat food low in zinc and also get phytic acid added, it makes their zinc levels drop even more compared to rats that don't get the extra phytic acid.

See the scientific wording

Adding phytic acid to a low-zinc diet exacerbates zinc deficiency in male rats, as shown by depressed zinc status compared to controls without added phytic acid.

What the research says

1 study

  1. Study: EDTA disodium zinc has superior bioavailability compared to common inorganic or chelated zinc compounds in rats fed a high phytic acid diet.

    The study shows that adding phytic acid to a low-zinc diet makes zinc deficiency worse in rats, which matches the claim exactly.
