The Claim
In adults aged 50–70, a daily protein intake of 1.0 g/kg body mass, distributed across meals and supplemented with either whey or pea protein, does not alter whole-body nitrogen balance over a 10-day period, indicating that this level of intake is sufficient to maintain nitrogen equilibrium regardless of protein source.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
For adults aged 50 to 70, consuming 1.0 gram of protein per kilogram of body weight each day, spread across meals and sourced from either whey or pea protein, maintains nitrogen balance over 10 days without change, regardless of the protein type.
See the scientific wording
In adults aged 50–70, a daily protein intake of 1.0 g/kg body mass, distributed across meals and supplemented with either whey or pea protein, does not alter whole-body nitrogen balance, indicating that this level of intake is sufficient to maintain nitrogen equilibrium over a 10-day period regardless of protein source.
When adults consume 1.0 gram of protein per kilogram of body weight each day, their bodies use the amino acids from that protein to build and repair tissues at the same rate they break down old proteins. This balance keeps the total amount of nitrogen in the body stable over time, no matter if the protein comes from whey or pea sources.
What the research says
1 studyThe study found that older adults who ate 1 gram of protein per kilogram of body weight each day — whether from whey or pea protein — didn’t lose or gain muscle protein overall over 10 days. So, that amount is enough to keep their body’s protein levels stable.
