Why Does Oat Milk Give Me Diarrhea?

The fiber and sugar in oat milk lead you to have diarrhea. Oat milk occasionally contains sugar, which together might stimulate bowel movements. In addition to the fiber, it might aggravate your digestive system and result in diarrhea.

Why do I tummy aches after drinking oat milk?

Oat sensitivity may cause milder symptoms to appear more gradually. However, if you consume or come into touch with oats frequently, these symptoms could become persistent. These signs consist of:

  • stomach inflammation and irritability
  • diarrhea
  • fatigue

A reaction to oats can result in dietary protein-induced enterocolitis syndrome in newborns and children (FPIES). This illness has digestive system effects. It may result in diarrhea, vomiting, dehydration, and stunted growth.

Lethargy and hunger can also result from FPIES, especially if it is severe or long-lasting. Oats are not the only food that can cause FPIES.

When applied topically, oat allergies can harm the skin as well. A high proportion of infants and kids who had atopic dermatitis in 2007 experienced allergic skin reactions to lotions and other products containing oats.

Adults who are allergic to or sensitive to oats and use products containing this component may also have skin responses.

Is oat milk compatible with lactose intolerance?

Many individuals are unaware that oat milk is genuinely lactose free. The ideal non-dairy milk substitute is oat milk. This is due to the fact that it has no lactose or dairy, making it a favorite among individuals who eat a vegan diet or have a lactose intolerance. Oat milk is frequently cited as the finest milk substitute for coffee since it is excellent for foaming. If a customer is lactose intolerant, we have Oatly oat milk available for delivery. We now also provide oat milk from Oato in glass re-usable bottles, which many customers believe to be the most environmentally friendly milk substitute. Oato is a lactose, nut, sugar, and soy-free, creamy, plant-based milk substitute. Freshest British ingredients are used in its preparation.

What negative impacts does oat milk have?

Although few people find oats to be a problematic component, there are occasionally some negative effects when first using oats.

The biggest problem is that your body isn’t used to processing a lot of fiber, and oats have a high fiber level. On the other hand, an oat allergy is a possibility.

However, one should be informed of the potential risks associated with oat milk so that they can take precautions before running into a stumbling block.

You could suffer the following negative consequences from ingesting oat milk:

  • Uncomfortable stomach: Since many people are not used to eating or drinking fiber-rich foods or beverages, they may first feel uncomfortable. Because of this, it is advised to start with small portions and gradually increase them as your body becomes used to consuming the fiber-rich meals.
  • Oats are rich in soluble and insoluble fiber, which will both help you transit stool through your intestines more quickly if you have diarrhea. Together, the two types of fiber soften and bulk up the feces, which ultimately makes it simpler to pass through the intestines.
  • Oats are inherently free of gluten; nevertheless, cross contamination in wheat processing equipment is the main source of exposure. Purchase gluten-free oat milk or prepare your own with gluten-free rolled oats if you have celiac illness or gluten sensitivity (14).
  • Oats are a complete grain that are high in carbohydrates. As a result of the complex carbohydrates’ high fiber content, which slows blood sugar absorption and digestion, they do not quickly raise insulin levels like simple carbohydrates do.

Apart from its negligible danger considerations, oat milk is advantageous and well-liked by many proponents of dairy-free beverages. It has had a huge increase in popularity because it is one of the greatest plant-based milk alternatives for vegans and health-conscious individuals.

Why does drinking oat milk make me feel ill?

Avenin, a protein found in oats, can make certain people react allergically.

After eating oats, a person may occasionally feel sick or exhibit symptoms of an oat allergy. However, it’s possible that they are intolerant to gluten. Celiac disease is a severe form of gluten sensitivity that affects one in 100 persons globally.

Oats don’t contain gluten, but processing them with gluten-containing foods can cause cross-contamination. This could lead to a wrong diagnosis.

This article examines the signs and symptoms of oat allergy, as well as some diagnostic criteria and available therapies.

Can adults become sick from eating oatmeal?

Avenin is a protein found in oats. It’s uncommon for persons with celiac disease to also experience an immunological reaction to avenin, but it can happen, according to the CDF. Few celiac patients had an adverse reaction to avenin, according to a study published in the December 2016 issue of the journal Medical Sciences.

According to the International Foundation for Gastrointestinal Disorders, soluble fiber, which is present in fruits, vegetables, and oat cereals, causes reactions in a small percentage of persons with IBS (IFGD). In contrast to insoluble fiber, soluble fiber dissolves in water.

Both forms of fiber are present in oat bran. If you have IBS, the IFGD advises trying several forms of fiber to determine if you get diarrhea after eating oatmeal or what you believe to be an oatmeal-related uncomfortable stomach. Always consult your doctor if you suspect oatmeal is the source of a stomach ache in order to rule out any major medical issues.

Oat milk: Is it a laxative?

When chewed incorrectly, oats can cause intestinal blockage, bloating, intestinal gas, digestive disorders, diarrhea, constipation, and other issues.

Oats’ high fiber content and the digestive system’s unfamiliarity with digesting the increased levels of fiber are the main problems with them, notwithstanding the tiny possibility of allergy.

In addition, inflammation brought on by gluten intolerance is a possibility. Although oats are gluten-free, there is a chance that cross contamination could have negative consequences if they are handled on equipment that also handles wheat.

Oat milk has a few downsides, including:

  • consists of both natural and added sugars
  • includes gluten
  • Canola oil was added.
  • include pesticides
  • Contains no nutritional value
  • higher calorie intake
  • greater expense
  • Complex plant-based carbohydrates

Not all the news is negative. Oats have numerous health advantages, and if your body can digest the entire grain, the superfood will undoubtedly have an effect.

Oats are also highly recommended for weight loss because their high fiber content prolongs the sense of fullness. The benefits might exceed the drawbacks if you can train your body to tolerate the fiber level of oats, which may need a slow adjustment period at first.

Does oat milk make you break out?

Your skin may break out if you drink oat milk. 20 grams of carbohydrates are found in one cup of oat milk, which can lead to insulin surges and hormonal acne.

Oat milk may also have minute quantities of gluten due to manufacturing. Inflammatory skin disorders can develop as a result of gluten sensitivity.

Oat milk’s high carbohydrate content can lead to hormonal acne. These are natural, plant-based carbohydrates that also contain added sugar in sweetened products.

Additionally, the majority of commercially produced oat milks contain trace amounts of gluten, which can cause skin irritation in those who are sensitive to gluten.

Does oat milk cause gas?

Yes, oat milk might result in gas if your stomach is irritated. This results from the fiber and sugar in the oat milk breaking digested.

The big intestine is where oat milk is transported. Oat milk can cause flatulence, burping, gas, and stomach pain if it is difficult to digest.

Additionally, it produces gas when combined with other components like granola or toppings. Oat milk contains soluble beta-glucan fiber and whole grain carbohydrates that might cause upset stomach by delaying digestion.

Can oat milk upset your stomach?

As the fiber and sugar in oat milk break down in your stomach and digestive system, it may cause stomach trouble. Because oat milk contains soluble fiber, it slows down digestion when it enters your body.

The same rules apply to stomach distress from oat milk as they do to gas. Oat milk’s beta-glucan, a kind of soluble fiber, can cause stomach distress.

This is a carb found in whole grains that takes in excess water and changes into a gel-like substance. It slows down digestion, which can cause gas, bloating, and stomach cramps.

Your stomach may also become upset if you have an oat allergy, so be aware of this possibility. The number of persons who truly have oat allergies is extremely small.

Can oat milk cause constipation?

Fiber in oat milk helps to treat constipation and IBS, or irritable bowel syndrome. Oat milk won’t make you constipated because it contains dietary fiber that lessens straining and constipation.

Oat milk contains soluble fiber that aids in treating constipation in persons who are chronically in need of it. Oat milk can help you with constipation symptoms, but use it sparingly since too much might have negative side effects.

Why does oat milk make you bloated?

Oat milk contains soluble fiber in the beta-glucan form, which might cause you to feel bloated. Bloating, intestinal gas, and upset stomach are possible side effects of this soluble fiber.

Whole grains contain the carbohydrate beta-glucan, and the soluble fiber offers various health benefits. They can, however, also impede your digestive process by soaking up additional water, which results in bloating, flatulence, gas, and unpleasant stomach symptoms.

Does oat milk make you poop?

Because oat milk contains fiber, it can reduce straining and constipation. You may then be able to poop and pass stool more easily as a result.

Oat milk’s fiber helps you relieve constipation and IBS symptoms by encouraging bowel movements. It is also known to lower the chance of dying from colorectal cancer.

Oat Milk Diarrhea

The likelihood of oat milk diarrhea is extremely unlikely if you choose natural oat milk without any added sugar. However, when combined with the high fiber content, commercial oat milk with significant levels of added sugar can be unhealthy and result in diarrhea.

Brands of sweetened oat milk improve the fiber content while also adding additional sugar. The first few times you consume the combo, if your body is not used to doing so, you can experience diarrhea until your digestion adjusts to the higher levels.

Some oat milk products contain gluten. Oat milk can give gluten intolerant persons diarrhea and upset stomachs.

Before buying, ensure that the oat milk is free of artificial sweeteners and gluten by reading the label. Oat milk is difficult for people with celiac disease and gluten sensitivity to digest, and even a small amount of exposure to wheat can cause upset stomach and diarrhea.

Oat milk (FODMAP content dependent on serve)

Oat milk is low FODMAP in small 30ml (1/8 cup) servings but high FODMAP in larger 125ml (1/2 cup) serves, making it unsuitable as a daily replacement for milk.

Soy milk made from whole soy beans (high FODMAP)

Whole soy bean soy milk has a high FODMAP content. In the USA and the UK, this kind of soy milk is popular. The milk will have a high FODMAP content if the ingredient list includes “whole soy beans.”

Standard cows’ milk (high FODMAP)

If the package does not specify that the milk is lactose-free, standard cow’s milk is high in FODMAPs. Full cream, reduced fat, or skim milk are all high FODMAP, even in tiny portions, because the lactose levels of cows’ milk are unaffected by the fat amount.

Oat milk is it difficult to digest?

Though it doesn’t provide quite the same health advantages as eating a bowl of whole grain oats, drinking milk made by soaking whole oats is still incredibly nutrient-dense.

Due to the oats’ natural sweetness, oat milk has a lot of carbohydrates. It is special because it has some soluble fiber, which gives oat milk a somewhat creamier texture.

Soluble fiber helps slow digestion and keeps you fuller for longer by absorbing water and turning into a gel during digestion. Additionally, it can aid in blood sugar stabilization.

And oat milk’s soluble fiber may lower your cholesterol levels. Oat milk consumption reduced LDL (bad) cholesterol levels during the course of a 5-week research in 52 men when compared to a control beverage (2).

The following nutrients are contained in an 8-ounce (240 ml) portion of Oatly oat milk, notwithstanding the fact that nutritional values might vary by brand and depend on how or whether the milk is fortified:

  • 120 calories
  • 3 grams of protein
  • 16 grams of carbs
  • 2 grams of fiber
  • 5 grams of fat
  • 50% of the DV for vitamin B12
  • 46% of the DV for riboflavin
  • 27% of the DV for calcium
  • 22% of the DV for phosphorus
  • 18% of the DV for vitamin D
  • 18% of the DV for vitamin A

Compared to most other plant milks, oat milk has more carbohydrates and fiber. Oats have a large amount of soluble fiber, which has many health advantages like lowering cholesterol and prolonging feeling of fullness.

Is oat milk healthy for the gut?

because it frequently contains calcium and vitamin D, both of which are beneficial for keeping strong bones.


Many people are unaware that oat milk is a good (plant-based) source of calcium, even though most people identify calcium with a glass of cow’s milk or a block of cheese.

A cup of oat milk containing 8 ounces has 300 to 400 mg of calcium, which is necessary for healthy, strong bone development.


Additionally, it contains potassium and magnesium, two elements known to be good for the bones.

Together, calcium and these two minerals support the health and strength of our bones.

For instance, potassium lowers bone loss whereas magnesium aids in calcium absorption. Potassium may also aid in calcium retention.


A happy, healthy gut

As eating foods containing beta-glucan has also been connected to gut health, oat milk is beneficial for the digestive system. 27

The beta-glucan concentration in oat milk does have a good effect on general gut health, according to a 2017 study.

They consumed Cuore Mio, pasta enhanced with barley beta-glucans (3g/100g), as part of a two-month diet regimen.


Healthy hair and nails

Oat milk is said to assist make our hair and nails stronger and shinier as well as promote faster growth, in addition to possibly mending and safeguarding our skin.

This is because oat milk contains the B vitamins that we described previously.


B vitamins also aid in reducing skin damage and promoting cellular healing by thwarting the oxidative damage that damaging free radicals cause to our cells.

Similar to how they do for skin, B vitamins encourage cell renewal in the hair, which helps prevent aging.


They might also affect the color of your hair; studies have shown that B12 deficiency can hasten graying and hair loss.


Feeling fuller for longer

Like a bowl of oatmeal in the morning, oat milk has the ability to keep you fuller longer.

This is because there is more fiber in almond milk—even if it may not be a lot—than there is in cow’s milk, which has zero fiber.


A diet high in fiber encourages fullness and enhances appetite control, which lessens the need for between-meal snacks.


They include increasing your levels of vitamin B, calcium, and dietary fiber, as well as giving you a healthy glow and stronger hair and nails. Additionally, it can keep you fuller longer.
