Uutta tutkimustietoa soijaproteiinistä

A study at McMaster University found that when it comes to muscle protein synthesis – building muscle basically – soy is no better than water. The researchers gave 30 men 0 grams of protein, 20 grams of soy, or 40 grams of soy at rest and after resistance exercise. They then compared the results to a group of men who had used 20 or 40 grams of whey protein instead.

While 40 grams of soy increased muscle protein synthesis a little, 20 grams of soy worked as well as 0 grams of soy. Both 20 and 40 grams of whey, however, increased muscle protein synthesis significantly. The researchers theorized that whey worked well (and soy didn't) because whey has a much higher percentage of leucine, the "master amino acid" for muscle building, than soy. Likewise, a higher percentage of the amino acids in soy, including leucine, are diverted towards oxidation, which makes them unavailable for protein synthesis.
