Drinking too many protein shakes could lead to an increased risk of obesity and a reduced lifespan, a new study has claimed.
Researchers from the University of Sydney have looked into the potential side effects from long-term high protein intake.
And they claim that excess consumption of branched-chain amino acids (BCAAs) can also negatively impact mood and lead to weight gain.
Diets high in protein and low in carbohydrates were also shown to have detrimental effects for health in mid to later life.
BCAA supplements are often consumed in the form of powder, which is then added to water to make a shake.
Decreased "happiness chemical".
Published in journal Nature Metabolism, the study found that while BCAAs help to build muscle, they can also negatively impact an individual's temperament, cause weight gain and lead to a shortened lifespan.
The team also found that high levels of BCAAs in the blood can disrupt sleep by causing decreased levels of the "happiness chemical" serotonin, which aids with sleep.
“While diets high in protein and low in carbohydrates were shown to be beneficial for reproductive function, they had detrimental effects for health in mid-late life, and also led to a shortened lifespan,” said Dr Samantha Solon-Biet, co-author of the study.
“What this new research has shown is that amino acid balance is important – it’s best to vary sources of protein to ensure you’re getting the best amino acid balance."
