This is a surprising paper just published in the American Journal of Clinical Nutrition. Don’t forget that allergy to casein (dairy protein) is a serious matter, but when that is not a factor note what the investigators found: “The dairy-supplemented diet resulted in significant suppression of oxidative stress and lower inflammatory markers and increased adiponectin, whereas the soy exerted no significant effect.” Just goes to show the importance of the scientific approach and an open mind.
