University of Sydney, Australia research reveals whey protein shakes from supplemental health stores may be bad for one’s health. They consist of whey proteins containing high levels of branched-chain amino acids (BCAAs). According to statistics in 2017, the global whey market is valued at $9.4 billion, growing to $14.5 billion 2023. Consisting of three essential amino acids known as leucine, valine and isoleucine, they are fairly low in essential nutrients and may have adverse long term effects.
During a study utilizing mice the University of Sydney researchers found BCAAs can impact mood, leading to weight gain, food cravings and perhaps a shortening of lifespan. Their data showcases the health costs for chronic high BCAA intakes and how they may be a consequence of hyperphagia driven amino acid imbalance.
