What to eat when you'reá with diarrhea (and what to avoid)

When you have diarrhea, it is important to prioritize foods with soluble fiber, such as white bread, white rice and white pasta, as well as opting for lean meats, such as chicken and fish, and peeled fruits, which will help with digestion, control the volume of bowel movements and relieve belly pain.

However, to avoid increased pain and episodes of diarrhea, it is also advisable to exclude processed and very fatty foods from the diet, such as ready-made sauces, fried foods and sausages, as well as milk, its derivatives and foods that can increase gas production, such as beans, chickpeas, broccoli or carbonated drinks.

In addition, it is essential to increase the intake of water, teas and coconut water to replace some nutrients and avoid dehydration, as a lot of water is lost through the faeces during a diarrhea crisis. Find out about other ways to help treat diarrhea.

What to eat

Foods that should be prioritized in the diet are those with soluble fiber and lean proteins, such as:

  • Pearless fruit, such as pear, banana, apple, guava, passion fruit, peach, cashew and lemon;
  • Fresh vegetables, such as zucchini, chayote, cassava, potato, yam, carrot, eggplant, green beans and asparagus;
  • Lean proteins, such as chicken, white fish, eggs, tofu and lean beef, such as muscle, soft top or lizard;
  • Low-fiber cereals, such as white rice, cornmeal, white bread, and white pasta.

In addition to food, coconut water helps to restore potassium and sodium, essential nutrients to maintain the body's functions, but which are eliminated in large quantities in diarrhea.

In addition, caffeine-free teas such as lemon balm, chamomile and rosemary are also important for increasing water replacement and have properties that soothe discomfort and aid digestion. Discover some teas that help in the treatment of diarrhea.

What to avoid

It is important to avoid some foods that can make diarrhea worse, including:

  • Fatty foods,such as milk and dairy products, fried foods, butter and cream;
  • Peel of fruits, such as pear, apple, plum and peach;
  • Oilseeds, such as walnuts, chestnuts, peanuts and hazelnuts;
  • Whole grains, such as brown rice, whole-grain pasta, whole-grain bread, and oatmeal;
  • Leaky vegetables, such as lettuce, arugula, kale, spinach, bertalha, Swiss chard and watercress;
  • Foods that increase gas production such as beans, radishes, chickpeas, broccoli, cauliflower, cabbage, lentils, cucumbers, sweet potatoes and Brussels sprouts;
  • Fatty meats, such as bacon, lamb, pork, rump steak, sirloin steak, flank steak and palette;
  • Processed foods, such as soft drinks, ready-made sauces, such as ketchup and mayonnaise, ice cream and instant noodles;
  • Spices such as pepper, curry, garlic and onion;
  • Embutidos, such as sausage, ham, salami, cup and bologna;
  • Sweets, such as sugar, guava, jam, chocolate, cakes, dried fruit and syrup.

It is also essential to avoid fruit juices, as this type of preparation contains a lot of fructose, which, in excess, stimulates bowel contraction, worsening diarrhea. In addition, caffeinated drinks such as coffee, mate tea and black tea should also be avoided during the crisis, as they can irritate the stomach and increase diarrhea.

Home remedies to treat diarrhea

Some home remedies can be used along with the diet to alleviate the symptoms of diarrhea, such as:

  • Chamomile tea;
  • Coconut water;
  • Carrot soup;
  • Apple juice;
  • Rice water.

In addition to these remedies, homemade serum also replenishes some nutrients, preventing dehydration and helping to control diarrhea. Learn how to prepare homemade serum.

When you need to take medicine

The use of medication to treat diarrhea should only be done with medical advice, because, in the event of an intestinal infection, taking medication to stop diarrhea prevents the body from eliminating the responsible microorganisms. Therefore, if there are symptoms that may indicate an intestinal infection, such as fever or bloody stools, it is important to consult a doctor to assess the cause of the problem and initiate the most appropriate treatment, which may include the use of antibiotics.

When diarrhea is not caused by bacteria, fungi or viruses, the doctor may prescribe anti-diarrheal drugs, such as loperamide and racecadotril, which will decrease bowel contraction, reducing diarrhea episodes.In addition, you may also need to take probiotic supplements, such as Lactobacillus reuteri and Lactobacillus casei, or prebiotic supplements, such as FOS, to fight bad bacteria in the gut and rebalance the intestinal flora.

Learn the main causes of diarrhea and what to do in each situation.

When to go to the doctor

It is important to be aware of symptoms and seek medical help if you have one or more of the following factors:

  • If diarrhea lasts longer than a week;
  • If you have signs of dehydration, such as dry mouth and skin, little urine, weakness, and feeling unwell.
  • Severe and persistent abdominal pain;
  • Black or bloody stools;
  • High fever.

It is important to remember that diarrhea is usually more severe in children and the elderly, and therefore greater care should be taken in these cases, seeking medical help if diarrhea continues for more than 3 days.
