Japanese medical studies link breastfeeding and IgA levels to metabolic health

New medical research from Japan highlights significant findings regarding metabolic health and disease risk indicators. One study involving approximately 500 women suggests that breastfeeding can help improve lipid levels in mothers who were diagnosed with gestational diabetes. The research indicates that as the proportion of infant nutrition provided through breast milk increases, blood lipid profiles move toward more heart-protective ranges. Specifically, meeting 80% of an infant's nutritional needs through breastfeeding was associated with reaching preferred lipid levels for cardiovascular protection.

In a separate study conducted by researchers at Shinshu University, scientists identified a potential blood marker for assessing risks in patients with Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD). The study, published in the ‘Journal of Hepatology’, found that elevated levels of Immunoglobulin A (IgA) can help identify patients at higher risk for serious liver complications. Among a group of 349 patients, those with IgA levels of 318 mg/dL or higher showed a higher incidence of advanced fibrosis and liver-related issues, even when advanced scarring was not yet present.
