Most of the milk drinks for meal replacement like Ensure/Glucerna taste OK, but I couldn't stomach it for more than a day. Each 1 ml given the standard dilution on the package is about 0.9 - 1 KCal i.e 200ml gives about 200Kcal, it makes it simple for calculation of calories in tube feeding patients.

Plus points= light weight, full nutrition
Minus points= Needs water to reconstitute, can be nasty tasting <img src="images/graemlins/tongue.gif" alt="" />

May be good to mix a few of these with powerbars, mainstay rations,mres for variety. These shakes alone....yuck!
