What Happens To The Protein You Eat?

When you consume a balanced meal, of the dietary protein that is broken down to the amino acid sub-units, around 90% is absorbed by the gut. It is thought that 30–50% will be used by the intestine to maintain its own structure and integrity, and the remainder (40-60%) is released into the portal system (general circulation) to be used by the organs and muscles.

It is suggested that an excess of protein could potentially lead to a reduction in total gut absorption, consequently reducing the percentage of protein absorbed into the body…basically you’d excrete more when nature calls!
