vegetables with fiber

How many times have you had diarrhoea this year? Did you cure it yourself, or did you have to see a doctor? In some cases, diarrhoea can be severe (1), and knowing the best foods to avoid it can help.

Do you know how to prepare and cook these ingredients? Have you considered the order in which you should add them back into your diet? Nutrition during an episode of intestinal discomfort is essential, (2) which is why we will explore the best foods to avoid diarrhoea in our article!

Key Facts

  • Diarrhoea can have many causes. That said, following an astringent diet for a few days can often slow it down without going to the doctor’s, hence the importance of dietary changes.
  • Taking probiotics daily could help prevent diarrhoea. If you don’t like fermented foods, you can always turn to Sundt Nutrition‘s probiotic supplements.
  • Our probiotic supplements not only guarantee a safe dose but also ensure the highest quality and a healthy microbiota free of harmful organisms. You won’t regret opting for Sundt Nutrition‘s probiotic supplements!

The Best Foods to Halt Diarrhoea

Did you know that our digestive system becomes more sensitive as we age? (3) Could it be something you eat that causes diarrhoea? For example, you may no longer be able to digest spices properly. Or maybe you’re not eating what you should: healthy foods that fight diarrhoea. Let’s have a look at some of them!

Start by replacing lost fluids!

THe first step when you have diarrhoea is to go through a stage of fasting and rehydration, which can last for a few hours to a day. Why? Because you need to replenish the fluids you have lost to prevent dehydration. This process also cleanses your body in case your diarrhoea is caused by food poisoning. Here are some fluids you can drink! (4, 5, 6, 7, 8)

  • Serum or water with salt, lemon, sugar, and baking soda. You can buy a commercial serum at the pharmacy or prepare it yourself with the ingredients mentioned and drink it during the first 24 hours.
  • Rice water. Prepare 50 g of rice in a litre and a half of water. You should drink the whitish water left after boiling it because it prevents diarrhoea and regulates intestinal transit.
  • Carrot water. Just like with rice water, simply boil the carrots until they are soft and drink the broth.
  • Chicken stock. This refers to a chicken broth without skin or any kind of fat. You can add vegetables like leeks and onions, but only drink the broth.
  • Infusions. Such as black tea or camomile.
  • Astringent fruit juices. This includes pomegranate juice or coconut water, amongst others.

Bring white rice into your life!

If you suddenly suffer from diarrhoea, you know know to start by rehydrating with serum. You can then progressively introduce solid food without fibre. But why white rice? (7, 8, 9, 10, 11)

  • Because it doesn’t contain any fibre. The fibres are good for going to the toilet, but not the other way around.
  • As it contains no fibre, it is an astringent food. This is exactly what you need to stop diarrhoea.
  • You can always make it taste better. For instance, you can fry a peeled garlic in a spoonful of olive oil.

Replace dairy products with almond milk!

You may be wondering why you can’t have dairy products. It’s simple: they have a high lactose content and take a long time to be digested. Natural skimmed yoghurt aside, dairy products can irritate your stomach even more. (7, 8, 9)

This temporary lactose restriction is also recommended for a number of reasons:

  • For lactase deficit. Lactase is the enzyme (a chemical) that our body uses to digest dairy products. It is often lacking when we have acute diarrhoea.
  • To prevent the proliferation of some microorganisms. These include adenovirus, E.Coli or rotavirus, amongst others, as they affect the small intestine.

However, you can replace cow’s milk with almond or oat milk. They are common in vegan diets, and we’re sure you’ll love them!

Rediscover the taste of boiled meat and fish!

We bet you forgot how they tasted! Well, boiled chicken or fish will come in handy for your aching stomach. Don’t use any spices or pepper, though. You can only add a tiny pinch of salt! (10, 11, 12)

Boiled meat and fish are the second stage of treating diarrhoea, as the consistency and frequency of stools improve.

Revive your taste for omelettes, hard-boiled eggs, boiled ham or grilled foods!

A boiled chicken breast doesn’t taste the same as a grilled one, right? Well, if you’ve done well with all our tips above, let’s move on to the next phase! You are now allowed to eat some foods like (13, 14):

  • Boiled ham
  • Grilled fish, veal or chicken
  • Hard-boiled eggs or French omelette
  • Non-wholemeal biscuits and flours

Foods to Prevent Diarrhoea: What You Need to Know

Diarrhoea can have many causes, which is why making a few dietary changes is the best solution during the first days. You can also choose to take probiotics, like Sundt Nutrition‘s products. We’ll tell you everything you need to know about them in this section!

Why is nutrition important when you have diarrhoea?

Did you know that starving yourself when you have diarrhoea is now a thing of the past? Taking care of your diet and replenishing fluids is essential to avoid dehydration and malnutrition. Here are the first steps to follow (19, 20, 21):

Prevent dehydration. Now that you know how to do it, don’t even think about drinking isotonic drinks! They don’t help you recover the minerals you need.

Follow an astringent diet. When you notice an improvement, you can introduce solid food very gradually and following the steps mentioned in this article.

Consult your physician. If the diarrhoea doesn’t stop after a few days on this soft or astringent diet, you should see your doctor. This is particularly important if you have blood or mucus in your stools or if you have a high fever, amongst other symptoms.

When are probiotics recommended?

As you may know, probiotics help repopulate the digestive tract with healthy bacteria, hence their importance in preventing and treating diarrhoea. In addition, they have been used to treat the following conditions (22, 23, 24):

  • Antibiotic-induced diarrhoea
  • Patients with irritable colon
  • Viral diarrhoea
  • Traveller’s diarrhoea

A probiotic supplement must contain at least 100 million to 1 billion CFUs (Colony Forming Units) to be considered effective. If you have diarrhoea, remember to buy probiotics with a safe dose, such as Sundt Nutrition‘s product.

Probiotic supplements to combat diarrhoea

Did you know that the intestinal microbiota is home to microorganisms whose function is to protect us from infection? You can increase these good bacteria through fermented foods (such as yoghurt) or by taking probiotic supplements. If you opt for the latter, make sure they are (22, 23, 24):

Traveller’s diarrhoeaBifidobacterium lactis, Bifidobacterium bifidum
Rotavirus diarrhoeaBifidobacterium lactis, Lactobacillus casei
Antibiotic-induced diarrhoeaLactobacillus GG and S. boulardii
Irritable bowel syndromeBifidobacterium longum, Bifidobacterium breve, Lactobacillus casei

If you don’t like yoghurt and don’t feel like eating fermented foods such as tempeh, kombucha or sauerkraut, we recommend Sundt Nutrition‘s probiotic supplements for the high quality standards in their manufacturing process. Get ready to say goodbye to diarrhoea!

Our Conclusions

Diarrhoea is a condition that we often suffer from a couple of times a year. An astringent diet is usually enough to make these watery stools disappear. If it’s not the case, you should consult your physician. But probiotics can help prevent diarrhoea altogether.

If you don’t like natural probiotics like yoghurt or if the astringent diet doesn’t appeal to you, opting for Sundt Nutrition‘s probiotic supplements will protect you from viruses and bacteria that are harmful to your microbiota – and you take them all year round! Check them out and see for yourself!
