What foods are commonly related to digestive discomfort?
What is the relationship between nutrition and the intestine? Food has a direct impact on digestion and can contribute to overall well-being[1]. In principle, you can eat everything, but some foods and beverages that are considered more difficult to digest or irritating should be consumed in moderation, according to individual tolerance[2]. On the other hand, other foods can contribute to a more balanced digestive system. Restrictions should not be considered a disadvantage: with some practical tips and a more conscious selection of foods, you can contribute to daily comfort and lead a more peaceful and active life.
Illustration of a balanced combination of foods related to intestinal comfort.
Observe which foods positively affect digestion and which are more frequently associated with discomfort.
Remember that tolerance is individual: the same food can be perceived differently by different people.
Sustainable small changes in nutrition usually have greater impacts than sudden and strict restrictions.
It's helpful to keep a food and symptom diary
Each organism reacts differently to certain foods and beverages, so it's very helpful to keep a food and symptom diary for some time[2]. In it, you record what you've eaten and drunk and when, as well as how you felt afterward. Don't forget to also note medications and dietary supplements, as these can also influence your overall condition. This way you can track which foods or beverages are tolerated better or worse individually[2]. Therefore, it's not necessary to completely exclude all potentially irritating foods, but rather to consume them according to the situation in moderation or adjust them. Each organism reacts differently, and what causes discomfort in one person may be of much less importance in another.
A food diary can also help you better understand your own habits. Those who know what and to what extent they tolerate can more easily avoid stress factors and make daily life more peaceful and active.

Foods that may be associated with greater digestive discomfort
Some foods and beverages are considered more irritating or more difficult to digest[8]. For sensitive intestines, it's important that they be consumed less frequently and in moderate amounts, according to individual tolerance[9].

🥔 Potassium-rich foods
Asparagus, bananas, or potatoes can contribute to mineral balance and have a positive effect on various metabolic processes[16].
🌶️ Spicy and acidic foods
Peppers, hot chilies, ginger, oranges, lemons, or tomatoes are often considered irritating for a more sensitive digestive system[10].
🥕 Root vegetables
Carrots, celery, parsnips, or parsley contain valuable nutrients, but can cause bloating in more sensitive people[11].
🫘 Foods that cause gas and bloating
Cabbage or legumes are beneficial, but can cause discomfort in sensitive intestines such as an excessive feeling of heaviness and bloating[12].
Suitable beverages for good digestion
For intestinal health, it's important that the body receives sufficient fluids[13]. Only then can metabolism stay in balance and digestion function optimally[14]. Insufficient fluid intake can negatively affect overall well-being[13].

Examples of fluid intake
The importance of adequate fluid intake throughout the day for overall well-being is often emphasized.
The best way to meet fluid needs is with water or unsweetened tea (for example, rooibos or unsweetened herbal tea).
