Kiwis are drinking increasingly less cow's milk.

Around 1.2 million fewer glasses are consumed every year, fuelling health concerns.

There's been a 17 % decline in the last two decades. 

ABC Nutrition's Angela Berrill told Mike Hosking it's largely due to the rapid rise of plant-based alternatives. 

She said it could be concerning if people reduce their dairy and milk intake but don't get calcium from other sources, as there may be an increased risk of osteoporosis and bone fractures when the younger generations become adults.
