Researchers at the University of Toronto conducted an extensive analysis of 17 previous studies involving more than 500 people to find out how replacing cow's milk with soy milk affects health. In each experiment, participants drank 500 ml of milk - cow's milk or soy milk - every day for four weeks. According to the Daily Mail, the results showed that replacing cow's milk with soy milk had a positive effect on a number of key health indicators. All participants who consumed soy milk saw a reduction in cholesterol, blood pressure, and inflammatory markers. One of the most important factors in this effect was that soy milk contains about 60% less sugar than cow's milk. Researchers note that the accumulated evidence points in favor of replacing cow's milk with soy milk because it may help improve blood lipid levels, normalize blood pressure, and reduce inflammation in adults.
