A new addition to the list is the prevention of muscle loss in older people.
40 healthy people aged 60-85 were randomised to n-3 PUFA pills whil 20 were given corn oil pills.
After 6-months, the first group showed increased thigh muscle volume and hand grip (Smith et al., 2015).
Bigger, better trials are needed before puffing PUFAs!
