The Claim
In French adults with early-treated phenylketonuria, lifelong adherence to a low-protein diet beginning after 1990 is associated with a higher prevalence of low bone mineral density compared to those who discontinued the diet.
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.
French adults with phenylketonuria who followed a low-protein diet their entire lives after 1990 have lower bone mineral density than those who stopped the diet.
See the scientific wording
In French adults with early-treated phenylketonuria, those born after 1990 who never discontinued their low-protein diet have a significantly higher risk of low bone mineral density, suggesting that modern dietary guidelines promoting lifelong adherence may contribute to this association.
Eating too little protein over a long time means the body doesn't get enough building blocks to make strong bone tissue, so bones become thin and weak.
What the research says
1 studyStudy: Bone mineral density in French adults with early-treated phenylketonuria.
People with PKU who stayed on their strict low-protein diet their whole life, especially those born after 1990, were much more likely to have weak bones than those who stopped the diet earlier. This suggests the current advice to stay on the diet forever might be linked to lower bone strength.
