Daily Walnut Consumption Linked to Slight Increase in IgG Levels in Older Adults

A two-year randomized trial with 474 older adults found that eating 30–60 grams of walnuts daily was associated with a 6% increase in total serum IgG levels, with an 11% increase among US participants. However, walnut intake did not significantly affect other immune markers, and the potential cardiovascular benefits of this IgG increase remain unclear.
