New findings from a large nationwide screening study of over 75,000 individuals suggest diet plays a limited role in the risk of monoclonal gammopathy of undetermined significance (MGUS), a precursor to multiple myeloma.
Investigators analyzed data from 27,217 participants who completed food frequency questionnaires. The study found no significant association between overall dietary patterns or individual food components and the development of MGUS.
A notable exception emerged in subgroup analysis: high dairy consumption was linked to increased odds of a specific MGUS subtype, immunoglobulin A MGUS. However, this isolated finding reinforces the broader conclusion that habitual diet is not a primary driver of MGUS risk.
These results indicate that dietary modification alone is unlikely to prevent the development of MGUS, prompting future research to explore other environmental or biological contributors to these blood disorders.
