|If you have switched from regular milk to a soy variety, you may have done so for the perceived health benefits or as part of a new diet. However, have you fully considered how soy milk could impact your oral health? A new study has actually shown that soy milk could be worse for your teeth than cow's milk.
This study was published in the Journal of Dentistry, and the results indicated that bacteria that are commonly found in the mouth produce 5-6 times more acid when they are allowed to feed on soy milk vs. cow's milk.
Since mouth acids result in plaque formation that eventually leads to tooth decay, this means that cow's milk is more likely to lead to cavities and other oral health concerns than cow's milk.
Researchers at the University of Melbourne examined four soy beverages and two cow's milk beverages or these experiments. All of the drinks were mixed with a certain type of bacteria that is found in the human mouth and is often associated with cavities.
It was found that with the soy beverages, the drinks became more acidic within ten minutes of adding the bacteria. However, the beverages that contained only cow's milk did not go through a significant change when the bacteria were added.
However, it should be noted that this study was completed in a lab, so more research is needed to fully understand the effects of soy milk on oral health. The cavity risk of soy milk will also depend on how you use the beverage, as one glass of milk isn't likely to cause any major damage to your teeth.
However, allowing your baby to nurse on a bottle of soy milk before bed might be a concern, as cow's milk isn't known to promote the development of cavities.
