In a controlled study* conducted in Bournemouth, England, older adults were encouraged to increase egg intake during a 3-month trial period.  A cohort of 100 elderly adults was randomized to either receive or not receive egg-based recipes and spice packs for a twelve-week period from June through December 2016.  Egg intake increased by 4-5 eggs per month.  No difference in lean body mass were determined after the twelve-week experimental period and for a subsequent twelve weeks. It is unfortunate that the trial did not evaluate lipid panels and metabolic parameters or cognition.
