A new Israeli study suggests that drinking cow’s milk may not only be good for kids. It may help them grow.

The independent study, conducted by Dr. Tali Sinai from the School of Nutritional Science at Hebrew University’s Faculty of Agriculture, followed kids that drank cow’s milk and those that didn’t.

The kids that drank cow’s milk ended up taller.

According to Dr. Tal Sinai, the study shows “without a doubt” a link between drinking milk and growth.

At times, the difference in height can be dramatic.

In an interview with Yediot Aharonot, Dr. Sinai pointed out that “Some of these children are even 10 centimeters shorter than their parents,” suggesting that they did not reach their full height.

According to Dr. Sinai the difference may be due to the fact that milk provides high-quality protein and nutrition for a growing child.

“Milk is a source of energy, of high-quality biological protein, of vital fatty acids, of vitamins and of minerals, which are all concentrated in one type of food. Children who don’t consume milk must find a way to make up the nutritional deprivations in order to prevent growth problems,” he said.

With the growing tendency in Israel and around the world to cut out animal products from the diet both for the environment and for personal health, the study showing that cow’s milk may be advantageous for kids, is sure to stir up some controversy especially among the growing anti-milk crowd.

In fact, while Sinai’s study seems to promote milk drinking, many experts say that kids need good nutrition, not milk, which is unnecessary after weaning.

“Do kids really need milk? No, of course they don’t,”Amy Lanou, a professor of nutrition at the University of North Carolina at Asheville told Live Science when asked recently if kids should be drinking milk at all.
