The Claim
In vitro exposure of human immunoglobulin G (IgG) to fructose at 5 mM for 28 days increases the formation of advanced glycation end-products (AGEs), as measured by fluorescence and Congo red spectral shifts, and reduces IgG's antigen-binding capacity.
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.
When human antibodies are exposed to high levels of fructose in a lab setting for 28 days, their structure changes in a way that reduces their ability to bind to antigens.
See the scientific wording
In vitro exposure of human immunoglobulin G (IgG) to fructose at 5 mM for 28 days significantly increases the formation of advanced glycation end-products (AGEs), as measured by fluorescence and Congo red spectral shifts, which reduces IgG's antigen-binding capacity, suggesting that high fructose concentrations may impair antibody function at the molecular level.
Fructose sticks to antibodies in a chemical reaction that creates stiff, abnormal clumps on the antibody surface. These clumps change the shape of the antibody so it can no longer grab onto germs properly, making it less able to fight infections.
What the research says
1 studyWhen antibodies (IgG) are soaked in high sugar (fructose) in a lab, they get damaged and can’t stick to germs as well — this study proved that happens. It’s like sugar gumming up the keys that antibodies use to unlock and fight infections.
