Curtin researchers claim regular milk drinkers could reduce their risk of stomach upsets by swapping to milk containing A2 type beta-casein proteins.
Associate Professor Sebely Pal, from Curtin University's School of Public Health, said that until now there had been no solid evidence to demonstrate that A2 milk had different gastrointestinal effects for humans than regular milk.
"The majority of the milk consumed in Australia contains the A1 protein," Professor Pal said.
Some of the people in the Curtin study who said they were intolerant to ordinary milk reported gastrointestinal benefits from an A1-free diet.
