There's concern about the high level of sugar in baby pouches.

The squeezy pouches are thought to make up around 70 percent of the baby food market.

The Health Research Council has granted money for academics at Otago University to look into the baby food issue.

Dietician Caryn Zinn says told Kate Hawkesby the main problem is the pouches are so focussed on fruit.

"People think that fruit is so healthy that they can eat unlimited quantities," she said.

"The reality is that these pouches are just full of sugar."

She said that mums are busy and need convenience so they turn to pouches.

"The intake of sugar that these kids have is mounting and potentially enormous, damaging dental health and potential obesity and diabetes long term."
