HEALTH UPDATE: skimmed milk best for pumping up muscle mass

Weightlifters who drink skim milk after a workout will build about twice as much muscle as those who rely on soya beverages, a new study suggests.
What's more, milk is far cheaper than supplements specifically designed to help weightlifters pump up after a workout, Dr Stuart M. Phillips of McMaster University in Hamilton, Ontario, the study's lead author, told Reuters Health. The researchers used powdered skim milk in the current study, available in any grocery store.
Consuming protein after "pumping iron" is known to help build muscle mass, Phillips and his team note in the American Journal of Clinical Nutrition, but it is not clear whether some types of protein are more effective than others.
