London:Giving kids whole milk may be a better option over skim milk, a new research has revealed.

According to Dr David S Ludwig, an endocrinologist at Boston Children's Hospital, and Dr Walter C Willet, Fredrick John Stare professor of epidemiology and nutrition chair at the Harvard School of Public Health in Cambridge wanted to find which milk is more nutritious.

Their study showed that 2 cups of milk is enough for children, CBS News reported.

The authors point out that there are only a few clinical trials that have looked at the benefits of reduced-fat milk compared to whole milk.

Most people just assume the lower-fat milk has fewer calories, which theoretically decreases total caloric intake and lessens weight gain.

However, researchers said that just because someone lowers fat intake doesn't necessarily mean that it will help with losing weight

Researchers said that a person may feel less full after drinking low-fat milk than if they’d had whole milk, making them more likely to consume additional calories.

The research was published on July 1 in JAMA Pediatrics.
