Differences from cow's milk

Soy milk has considerable differences compared to cow's milk. Fundamentally it is distinguished by the types of nutrients it contains. Another difference is the amount of iron: cow's milk contains more than soy, especially whole milk. 

According to Josep Antoni Tur, professor of physiology at the University of the Balearic Islands, whole milk is rich in saturated fatty acids and has cholesterol; on the contrary, soy milk lacks cholesterol, which is replaced by phytosterol (plant cholesterols) and has polyunsaturated fatty acids.

Cytosterol does not have harmful effects on the body. The amount of fat in the soy drink is lower, with an amount equivalent to that of semi-skimmed milk.

The study makes a comparison between both drinks and states that soy has a lower energy value than cow's milk (650 kcal from a liter of whole milk compared to 524 kcal per liter of soy drink). In the same way, the calcium contribution of soy milk is lower than that of cow's milk, specifically 100 milligrams per 100 grams of soy drink.
