Does Almond Milk Cause Constipation?

Constipation occurs when one has difficulty emptying their bowels 1. A person with constipation may poop less than three times per week. Several dietary-related factors cause this condition, the primary cause being a low fiber intake 2.

Almond milk doesn’t make you constipated because of its high fiber content 3. 

However, some store-bought almond milk brands may trigger stomach upsets, including constipation, due to the various additives in the end product, e.g., thickeners and artificial flavors 4.

Here are five reasons why commercially processed almond milk may trigger constipation:

  1. Some commercially produced almond milk brands are fortified with calcium carbonate to boost calcium naturally present in animal-based milk but significantly low in plant-based milk alternatives. Although the calcium carbonate helps mimic regular milk, most manufacturers go for cheap calcium carbonate often highly concentrated. 
  2. A high calcium intake can interfere with the digestive system causing constipation, bloating and kidney stones, among other gastrointestinal issues 5.
  3. Artificial flavors added to enhance the almond milk’s flavor cause digestive issues linked to constipation.
  4. Given that almond milk is made from almonds, individuals with nut sensitivity can get constipation from its consumption.
  5. Some brands contain questionable ingredients like carrageenan obtained from red algae. Such components are linked to gastrointestinal issues, including constipation. Therefore, it’s advisable to read the ingredients list on the packaging before getting a certain almond milk brand from the stores 6.
