Are you wondering why your favorite dairy-free alternative, almond milk, is causing an unpleasant side effect like diarrhea? You’re not alone. Many people experience stomach troubles and digestive issues after consuming almond milk, unaware of the possible culprits hiding within this seemingly healthy beverage.

In this blog post, we will delve into the reasons behind this uncomfortable reaction to almond milk and explore ways to manage it effectively.

Understanding The Causes Of Diarrhea From Almond Milk

High Fiber Content

Almond milk has gained popularity in recent years, particularly among those who are lactose intolerant or simply seeking a dairy-free alternative for their everyday consumption.

However, one potential downside of this beverage is its high fiber content, which can sometimes lead to digestive issues such as diarrhea.

The presence of high fiber content in almond milk can have various effects on the body: while it may help regulate bowel movements and maintain healthy digestion for some individuals, others may experience an increase in stomach discomfort and loose stools when consuming too much of it.

In fact, excessive intake of almond milk can exacerbate existing digestive problems like dysentery or irritable bowel syndrome (IBS).


Carrageenan, a common additive found in non-dairy milk products such as almond milk, is derived from red seaweed and used for its thickening and stabilizing properties. Although it’s considered safe by regulatory agencies like the FDA, it has been linked to several gastrointestinal issues affecting individuals who consume almond milk regularly.

One possible reason behind these reactions could be that carrageenan acts as an irritant to the gastrointestinal tract in some people. Elimination of carrageenan-containing almond milk from one’s diet might actually alleviate abdominal pain and diarrhea symptoms they experience after consuming this popular nondairy beverage option.

If you’re prone to experiencing negative side effects from alcohol consumption or have pre-existing GI conditions such as IBD or irritable bowel syndrome (IBS), drinking almond milk with carrageenan may exacerbate your symptoms further.

Almond Allergy Or Intolerance

One of the primary reasons almond milk may cause diarrhea is due to an allergy or intolerance to almonds. Almond sensitivity, a type of tree nut intolerance, can lead to digestive discomfort after consuming almond milk or other products containing almonds.

For those with nut allergies, even a small amount of almonds can trigger gastrointestinal symptoms such as stomach pain, cramping, bloating, flatulence, diarrhea, and nausea.

An allergic reaction involving a substance called histamine causes these unpleasant side effects in individuals with almond allergies or intolerances. For example, someone struggling with alcoholism may already have a compromised digestive system due to their drinking habits (liver issues), making them more susceptible to experiencing severe gastrointestinal symptoms when exposed to allergens like nuts.

The Role Of Magnesium In Almond Milk And Digestion

Magnesium in almond milk can affect bowel movements by softening stools, which may contribute to diarrhea.

Magnesium’s Effect On Bowel Movements

Magnesium is a mineral that plays an essential role in regulating our digestive function. It can help to maintain bowel health and regulate gut bacteria balance, ensuring that we have healthy stools and avoid constipation.

Almond milk contains a good amount of magnesium, which makes it ideal for people with digestive problems such as constipation or diarrhea caused by low intakes of this micronutrient.

Drinking almond milk regularly may lead to smoother bowel movements if consumed in moderation.

Almond Milk’s Magnesium Content

Almond milk is a great source of magnesium, an essential mineral that helps regulate heartbeat and supports healthy muscle function. Magnesium also plays a crucial role in helping transport other nutrients through the body, such as calcium and potassium.

However, almonds contain phytic acid, which can reduce the absorption of magnesium. It’s important to note that low levels of magnesium in the body can lead to several health concerns like high blood pressure and type 2 diabetes.

Managing Diarrhea From Almond Milk

To manage diarrhea from almond milk, limit your intake, choose brands with lower fiber and carrageenan content, and consult with a healthcare provider if symptoms persist.

Limiting Intake

If you’re experiencing diarrhea after consuming almond milk, one simple solution is to limit your intake. Cutting back on the amount of almond milk you drink can help regulate your digestive system and reduce the likelihood of bowel problems.

It’s also a good idea to gradually introduce almond milk into your diet if you haven’t consumed it before as a sudden increase in fiber can cause stomach discomfort and other digestive issues.

Additionally, choosing brands with lower fiber and carrageenan content may be helpful in managing diarrhea caused by almond milk consumption.

Choosing Brands With Lower Fiber And Carrageenan Content

To manage diarrhea from almond milk, one solution is to choose brands with lower fiber and carrageenan content. Some people may have a sensitive gut and cannot tolerate the high fiber in almond milk.

Carrageenan, an additive used as a thickener in some brands of plant-based milk, can also cause digestive symptoms like nausea and severe stomach pain. To avoid these issues, it’s important to check the label before buying almond milk.

For instance, if you find that drinking regular unsweetened almond milk causes digestive upset or loose stools for you or your little ones, you might want to try organic almond milks without added gums or stabilizers like carrageenan.

Alternatively, choose unsweetened vanilla flavored versions which tend to contain less thickeners than flavors like chocolate and vanilla creme.

Consulting With A Healthcare Provider

If you’re experiencing diarrhea after drinking almond milk, it’s essential to consult a healthcare provider. They can help diagnose any underlying conditions that may be causing the problem and provide advice on how to manage your symptoms.

A healthcare provider can also advise on the amount of almond milk to consume based on your dietary restrictions and nutritional needs. In some cases, limiting intake may help reduce digestive issues caused by high fiber content or carrageenan in certain brands of almond milk.

Other Possible Side Effects Of Almond Milk

In addition to diarrhea, drinking almond milk can also lead to stomach discomfort and other bowel problems due to its high fiber content and carrageenan additives.

Stomach Discomfort

If you’re experiencing stomach discomfort after drinking almond milk, it could be due to the high fiber content or the presence of carrageenan.

Carrageenan is a food additive used as a thickener in many processed foods and has been linked to gastrointestinal distress. Symptoms can include gas, bloating, nausea, and severe stomach pain.

In addition, if you have an almond allergy or intolerance, consuming almond milk could result in diarrhea or vomiting. It’s essential to limit your intake of almond milk and choose brands with lower fiber and carrageenan content if you are susceptible to digestive problems.

Bowel Problems

Drinking almond milk can cause various digestive issues, including bowel problems such as diarrhea and dysentery. These symptoms may arise due to the high fiber content in almonds or carrageenan, a common ingredient used in almond milk to improve texture and flavor.

If you experience bowel problems after consuming almond milk, it’s essential to limit your intake and choose brands with lower fiber and carrageenan content. Consulting with a healthcare provider can also help identify any underlying food allergies or intolerances that may be causing the symptoms.


If you’ve experienced diarrhea after drinking almond milk, there may be several reasons why. The high fiber content and carrageenan in almond milk can contribute to digestive problems, while magnesium can affect bowel movements.

To manage these symptoms, consider limiting your intake or choosing brands with lower fiber and carrageenan content. If symptoms persist, consulting with a healthcare provider is recommended.
