This is an interesting chart, although sort of confusing. It contrasts the merits of 3 different protein types: whey, casein, and soy. It then goes on to ignore casein and introduce products that contain either whey protein only, soy protein only, or a 50/50 mixture. This is also interesting coming from a dairy company which, most of which usually only praise dairy protein in the ongoing dairy protein vs soy protein debate. With the WHO coming out with a report last year which supports dairy protein as superior, one might have thought that the debate was over. In any case, this is a thumbnail of the points made:
1) whey protein contains branched chain amino acids, which help build muscle and support immune function and are quickly absorbed by the body. Therefore whey protein is good for "junior athletes" who want to get bigger and for recover after sporting events.
2) soy protein supports metabolism, does not contain undesirable fats, supports immune function, and contains antioxidants (flavonoids). Therefore soy protein is good for athletes who want to build lean body mass.
One of the pictured products contains 100 percent whey protein, the second 100 percent soy protein, and the third a 50/50 mixture. 明治 ザバス
