Question: Protein powder

 basketball - Tue Oct 04, 2005 7:19 pm

My 2 sons are 15 years old. They have just recently started drinking 100% whey protein shakes. I wanted to know what you think of the shakes. I have heard that if you drink an excess amout it can cause kidney problems. My sons drink 2 shakes a day, which is about 50 grams of protein. Could you please tell me if they should stop having or if it is harmful.

They are adolescents and they have grown plenty so far (15 years) but still are growing to a less degree and therefore the protein needs are less than if they were 13 for instance. Their daily needs are around 1 gram per Kg. It means that they are taking a good amount of protein with the shake only.Obviously they eat in their diet more protein, if it is balanced then they are probably taking more than what they need and the excess of protein will be transformed into fat so it might not make sense to take additional protein intake once they are having a good and balanced diet.
