Protein shakes are often promoted as a healthy product. In 2017, people spent $9.3 billion on protein shakes. Experts are predicting that the number will increase to $14,3 billion by the year 2023. However, a new study has shown that protein shakes can actually put your health at risk.
Protein shakes contain branched chain amino acids. They are made up of three essential amino acids, which are isoleucine, leucine and valine. People believe that the branched chained amino acids can help build muscle. However, some scientists say that there is no evidence to show that branched chain amino acids help with bodybuilding.
A study done on mice showed that branched chain amino acids can be harmful. The study showed that diets that are high in branched chain amino acids are often low in the essential nutrients that people need. They can also lead to poor mood, food cravings and shorten one’s lifespan.
The results of the study were published in a journal called “Nature Metabolism.” Results from previous studies were also used. Samantha Bolon-Bet was the co-lead author of the study. She stated that high-protein, low-carb diets can benefit reproductive health in the short-term. However, these diets can have detrimental effects on health in the long-term.
The study found that when mice were given branched chain amino acids, their serotonin levels dropped. Serotonin is a neurotransmitter that promotes happiness. It can also help one sleep. The study also showed that when the mice had lower levels of serotonin, they were more likely to overeat and become obese. This led to a shorter lifespan.
