Your Protein Shakes Might Be Related To Depression

You may want to think twice before guzzling down your favorite protein shakes. A new study shows that the pre and post workout drink can lead to depression.

Researchers over at the University of Sydney discovered that the consequences of long-term consumption of protein shakes are caused by certain amino acids that can be found in the beverages. So while you are building muscle, the branched-chain amino acids are reducing your lifespan, causing mood changes and contributing to weight gain.

“While delivering muscle-building benefits, excessive consumption of branched-chain amino acids (BCAAs) may reduce lifespan, negatively impact mood and lead to weight gain,” Dr. Samantha Solon-Biet concluded. While doing their study, the researchers found that the BCAAs compete with the tryptophan that travels to the brain.

If you don’t know much about tryptophan it is a precursor to the hormon serotonin, also known as the “happiness chemical.” Due to BCAAs and tryptophan basically competing for a spot in your brain it causes serious issues for those who indulge in protein shakes.

“This then lowered serotonin levels in the brain, which in turn was a potent signal to increase appetite. The serotonin decrease caused by excess BCAA intake led to massive overeating in our mice, which became hugely obese and lived shorter lives.”
