What makes them so sure Oxalic acid prevents bone formation?!
I have heard thatit bondsto calcium, thus preventing absorbtion, however, the plants that have this stuff also have calcium, as well as other stuff we need to form bones, like vitamin K and Magnesium, and zinc!. It doesn't stand to reason that nature would put that good stuff in a plant and then something that would take away all out calcium!. Is there any substancial studies that show getting vegetables high in Oxalic acid decreases bone formation!?Www@FoodAQ@Com

Quick search of pubmed led me to this 2007 paper:
Increased calcium bioavailability in mice fed genetically engineered plants lacking calcium oxalate!.

Vegetable and Fruit Improvement Center, Texas A&M University, College Station, TX 77845, USA!.
Bioavailable calcium affects bone formation and calcification!. Here we investigate how a single gene mutation altering calcium partitioning in the model forage crop Medicago truncatula affects calcium bioavailability!. Previously, the cod5 M!. truncatula mutant was identified which contains identical calcium concentrations to wild-type, but contains no oxalate crystals!. In this study, equal number of male and female mice were randomly grouped and then fed one of four 45Ca-containing diets: M!. truncatula extrinsically or intrinsically labeled, and cod5 extrinsically or intrinsically labeled!. Absorption of the tracer was determined in the legs one day after consumption!. The absorption was similar in the M!. truncatula and cod5 extrinsically labeled diets; however, in the intrinsically labeled diets, calcium absorption was 22!.87% (P < 0!.001) higher in mice fed cod5!. Our study presents the first genetic evidence demonstrating the nutritional impact of removing oxalate crystals from foods!.Www@FoodAQ@Com

They probably fed some animals lots of it and saw that their bones didn't develop!. You could go to Asia and buy some children and test it on humans if you don't believe in animal testing!.
Evolution does not work in the way you think it does!. Oxalic acid is a poison that probably evolved to stop plants from being eaten by bugs or other animals!. A large dose from eating rhubarb leaves can kill a man!.Www@FoodAQ@Com

They have researched this!. That's why they're sure!. Do any plants that have oxalic acid in them also have bones!? Www@FoodAQ@Com
