Does Soy Milk Cause Constipation?

Soy milk, a highly nutritious drink, is made by soaking, grinding and boiling soy beans with water. Besides being a particularly rich source of protein, soy milk also contains essential fatty acids, vitamins, potassium, iron and dietary fiber. These active ingredients provide a very good amount of energy and help your body function as smoothly as possible.1

What Causes Constipation?

Causes of constipation


You could feel constipated because of a whole host of reasons. However, what you eat or drink definitely has an impact on your bowel movements. Compared to adults, constipation mostly affects infants or children causing significant discomfort in the little ones.

Usually, we all consume milk that’s pasteurized and contains antibiotics as well as hormones. However, during the pasteurization process, some of the valuable enzymes that aid digestion are removed.


If you consume too much milk and very little fiber in your diet, you are prone to constipation and flatulence. If you are lactose intolerant, you are more likely to be constipated every time you have a glass of milk. Soy milk, on the other hand, does not cause constipation. It actually helps relieve constipation symptoms. A recent study proved that constipation was resolved in children consuming soy milk, while those consuming cow’s milk still felt constipated. 2

Unfortunately, there’s very little medical research done regarding the relation between soy milk and constipation. Although, it is widely known that soy protein can be an allergen and lead to constipation eventually.

The soy protein is one of the eight allergens that come under the labeling requirements of the Food Allergen Labeling and Consumer Protection Act. To make things simpler, if you’re allergic to soy, ensure that you don’t consume soy milk at any point in time.


In such a situation, the best way forward is for you to replace soy milk with either almond milk or rice milk.3
