A higher fat content in the diet could be an advantage for preventing malnutrition among older adults. However, there is sparse scientific evidence to determine the optimal fat intake among older adults. This prospective cohort study examined whether a high energy intake of dietary fat among middle-aged and older adults is associated with the risk of malnutrition 10 years later. The study population comprised 725 Swedish men and women aged 53–80 years who had completed a questionnaire about dietary intake and lifestyle factors in 1997 (baseline) and whose nutritional status was assessed when admitted to the hospital in 2008–2009 (follow-up). At the follow-up, 383 (52·8 %) participants were identified as being at risk of malnutrition and fifty-two (7·2 %) were identified as malnourished. Multinomial logistic regression models were used to analyse the association between previous dietary fat intake and nutritional status later in life. Contrary to what was expected, a high energy intake from total fat, saturated fat and monounsaturated fat among middle-aged and older adults increased the risk of exhibiting malnutrition 10 years later. However, this applied only to individuals with a BMI<25 kg/m² at the baseline. In conclusion, these findings suggest that preventive actions to counteract malnutrition in older adults should focus on limiting the intake of total fat in the diet by reducing consumption of food with a high content of saturated and monounsaturated fat.
