Nonetheless, this hyperlink is just not essentially associated to carrageenan, however presumably solely with a type of degraded carrageenan known as poligeenan. Not like carrageenan, poligeenan is just not accredited to be used as a meals additive (4).

Though it’s been established that protein has helpful results on blood strain, researchers on this examine linked soy milk’s blood-pressure-lowering results with the drink’s content material of a particular isoflavone known as genistein (13, 14).
