Hot off the press from Uppsala and Stockholm:
A high energy intake from dietary fat among middle-aged and older adults is associated with increased risk of malnutrition 10 years later.
"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."
Repeat after me. Association does not prove causation. How anyone dare suggest an experimental intervention on a large subpopulation of their nation based on an observational association within a subgroup of the target population is beyond me. How dare they?
It must be embarrassing to be a dietitian in Sweden nowadays but this sort of intervention recommendation is not going to decrease the stupidity index of mainstream dietary advice.
Hopefully sensible people will continue to ignore them!
