Drinking too much protein shakes could reduce your life
Hitting a protein shake right after a workout is often as satisfying as the exercise itself. Work done, gains made, reject this thing for maximum muscle building.

But the popularity explosion of shakes (and bars) of amino acid packaging could have a negative side effect. And when we say a negative side effect, we mean premature death. Damn.
These are the findings of a new research from the Charles Perkins Center of the University of Sydney in Australia and published this week in Nature Metabolism.
WHEN RAMJET TAKES HIS PILL OF PROTEINS
The research was led by Professor Stephen Simpson and Dr. Samantha Solon-Biet. In collaboration with their co-investigators, Simpson and Solon-Biet have found that while branched amino acids (BCAA) in protein shakes provide muscle building benefits, excessive consumption can not only reduce shelf life, but also kill your mood and lead to weight gain.
"While high-protein and low-carbohydrate diets have proven to be beneficial for reproductive function, they have had adverse health effects at the end of life and have also led to a reduction in life span" Solon-Biet said in a press release.
"What this new research has shown is that the amino acid balance is important – it's best to vary the protein sources to make sure you get the best balance of amino acids." "
So what's going on? Well, the bad mood, the weight gain and the reduction in the life span are all related, oddly enough.
By working with mice, the researchers found that high levels of BCAAs in the blood competed with tryptophan, another essential amino acid, for transport into the brain. Tryptophan is the only precursor to serotonin, the "chemical of happiness," which not only improves mood, but also promotes sleep. This is a fairly serious problem right away, but a drop in serotonin is also a powerful signal to increase appetite.
For the experiment, the mice were fed for life either double the normal amount of BCAA, or the standard amount, or half or fifth. Mice fed with the double amount of BCAAs increased their food intake, which resulted in obesity and decreased longevity.
"The decrease in serotonin caused by excessive consumption of BCAA resulted in massive overfeeding in our mice, which became extremely obese and led a shorter life," explained Simpson.

YOU MUST FIX YOUR PROTEINS
Not that you necessarily need to throw this whey protein cartridge into the garbage chute. Researchers say, however, that you must make sure that you mix your protein to get a good variety of amino acids.
For BCAA's, use red meat, chicken, fish, eggs, beans, lentils, nuts and soy protein. Prepare your tryptophans by including seeds, nuts, soy, cheese, chicken, turkey and, um, crocodile (crazy Australians) in your diet.
