This is an intervention study, aiming to increase protein intake, by increasing egg consumption in community dwelling older adults aged 55 years and over, by providing recipes to increase flavour and variety in egg dishes.
Individuals will be randomized to either receive the intervention or to a control group, where the intervention group will receive 6 recipes every two weeks for a 12 week period, and at the start, after 12 weeks and after 6 months egg intake, protein intake, body protein status, and various functional measures of muscle function will be assessed in both intervention and control group.

6 recipes will be provided every 2 weeks by post for 12 weeks
Egg Intake
Egg intake at the end of the intervention period, assessed using an adapted Food Frequency Questionnaire (FFQ)
Time frame: Change from baseline to 12 weeks
Adverse Events
Self-declared adverse events over the intervention period, assessed by questionnaire
Time frame: Change from baseline to 12 weeks
Change in Dietary Protein Intake
Change in dietary protein intake over the intervention and follow-up period, assessed using an adapted FFQ
Time frame: Change from baseline to 12 weeks
Muscle Function
Muscle function over the intervention and follow-up period, assessed using the Short Physical Performance Battery (Guralnik JM, Simonsick EM, Ferrucci L, Glynn RJ, Berkman LF, Blazer DG, Scherr PA, Wallace RB. (1994) A short physical performance battery assessing lower extremity function: association with self-reported disability and prediction of mortality and nursing home admission. J Gerontol 49:M85-M94). Higher scores denote better ability - range - 5.0 to +5.0.
Time frame: Change from baseline to 12 weeks
Lean Body Mass
Lean body mass over the intervention and follow-up period, assessed using bioimpedance
Time frame: Change from baseline to 12 weeks
Egg Intake
Egg intake over the follow-up period, assessed using an adapted FFQ.
Time frame: 6 months
Number of Adverse Events Reported
Self-declared adverse events over the follow-up period, assessed by questionnaire
