The United States Government has been pushing for more full-fat dairy products, and one Kiwi expert confirmed there's health benefits.

Robert F. Kennedy jnr has said for months that he wants the Government to endorse whole milk, reversing its earlier claims that Americans should consume low-fat milk and cheese to reduce the health risks.

Nutritionist and AUT professor Caryn Zinn says there's a 'substantial' body of evidence that shows full-fat milk is healthier. 

"Full-fat dairy products actually outperform low-fat dairy products when it comes to a number of chronic diseases - including lowering risk of childhood obesity, cardiovascular disease and type two diabetes."
