This is intriguing, Julie!
I searched"pea based infant formula risks" in PubMed and only this study came up:
https://pubmed.ncbi.nlm.nih.gov/37150637/
Urolithiasis appears to be a fancy term for kidney stones.
This is an interesting study about soy-based formula: 

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6456922/
     And here is an interesting discussion about plant-based formula and drinks:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10094203/
Thank you for posting about this topic.

Subject: "Plant based" formula

I've been seeing a new "plant based" formula on the shelves recently.  It
has a pea protein base.  I'm wondering if anyone here anticipates specific
long term problems from this.  For example, (one of my textbooks states)
there is an associated increased risk of thyroid problems and infertility
in women who were soy-formula-fed as infants.

 How different are peas from soy beans?  They are both legumes.  What sort of peas are they talking about and what sort of beans? and what does it mean for a baby to grow on a plant based product and not mama's milk??  Will it make a difference in lifelong growth?.  We know for sure it makes a difference in immunity!  Pat in SNJU
