BACKGROUND AND AIMS: Correction of calcium and protein undernutrition using milk, yoghurt, and cheese in older adults in aged care homes is associated with reduced fractures and falls. However, these foods contain potentially atherogenic fats. We aimed to determine whether this intervention that increased dairy consumption to recommended levels adversely affects serum lipid profiles. METHOD AND RESULTS: This was a sub-group analysis of a 2-year cluster-randomised trial involving 60 aged care homes in Australia. Thirty intervention homes provided additional milk, yoghurt, and cheese on menus while 30 control homes continued with their usual menus. A sample of 159 intervention and 86 controls residents (69% female, median age 87.8 years) had dietary intakes recorded using plate waste analysis and fasting serum lipids measured at baseline and 12 months. Diagnosis of cardiovascular disease and use of relevant medications were determined from medical records. Outcome measures were serum total, HDL and LDL cholesterol and ApoA-1 & B. Intervention increased daily dairy servings from 1.9 ± 1.0 to 3.5 ± 1.4 (p < 0.001) while controls continued daily intakes of ≤2 servings daily (1.7 ± 1.0 to 2.0 ± 1.0 (p = 0.028). No group differences were observed for serum total cholesterol/high-density lipoprotein-C (TC/HDL-C) ratio, Apoprotein B/Apoprotein A-1 (ApoB/ApoA-1) ratio, low-density lipoprotein-C (LDL-C), non-HDL-C, or triglycerides (TGs) at 12 months. CONCLUSION: Among older adults in a...
