Q: Is it possible to eat too much protein?
A: Like other food sources, too much of a good thing is not good at all. High protein intake also means ingesting excess calories and placing strain on your kidneys.

How do you know if you are eating too much or too little? Following the standard rule of 0.8 grams of protein per 1 kilogram of body weight is suggested. If you’re physically active, it’s OK for your intake to be a little bit higher to help with muscle repair and gain.
But you shouldn’t feel you have to eat strictly meat to help rebuild muscles. A variety of healthy protein sources are available for all diets.
If you’re wandering down the aisles looking at the countless tubs of protein powders, choose one that’s organic, has the fewest ingredients and is tested by a third party. Regulations for ingredients in protein powders are more lax, so it’s reassuring to know another source has verified the ingredients in a powder are safe and healthy.
