Tomatoes can upset your stomach: When to avoid eating them
Tomatoes are undoubtedly one of the most popular and healthiest vegetables that grace our tables all year round. They are rich in lycopene, vitamin C, potassium, and other valuable nutrients. However, while it seems that they can be eaten at any time of the day, nutritionists are increasingly pointing out when it might be better to avoid them. It turns out that not every time is suitable for consuming tomatoes.
Tomatoes are associated with lightness and health. They are a staple of summer salads, a great addition to sandwiches, and a base for many dishes. We enjoy them at almost any time of day, often without considering whether it's always a good idea. Meanwhile, nutritionists are increasingly emphasizing that not every moment is the right time to reach for these red, juicy vegetables.
Tomatoes — not only delicious but also very valuable
Although we treat them as a mere addition to sandwiches or salads, tomatoes are a true treasure trove of valuable nutrients. They contain few calories while providing the body with a solid dose of vitamins and minerals. We primarily find vitamin C, which strengthens immunity, vitamins A and E that support vision and skin health, as well as potassium, important for proper heart function.
However, one of the most valued components in tomatoes is lycopene — a powerful antioxidant with proven anti-cancer effects and supportive of cardiovascular health. Interestingly, its absorbability increases after thermal processing, which is why not only fresh tomatoes are valuable, but also sauces, purees, and passata.
Thanks to their low-calorie content and high water content, tomatoes perfectly hydrate the body and support a healthy diet. However, it's worth remembering that despite all their benefits, they should not be consumed in every situation — for example, on an empty stomach when they can harm a sensitive stomach.
Why is it not advisable to eat tomatoes on an empty stomach?
Although tomatoes are considered light and healthy, consuming them right after waking up when the stomach is still empty may not be the best idea. Before the body "gets going" with digestion, the acidic components in tomatoes can act as irritants. This is especially true for people with sensitive stomachs, prone to heartburn or reflux. That's why nutritionists suggest reaching for more neutral foods on an empty stomach.
If you're eating tomatoes — it’s best when the stomach is no longer empty and can handle processing acidic components better. Here’s what might happen if we ignore this rule:
- Acidity and the stomach - tomatoes are naturally acidic and contain many organic acids, such as citric and malic acid. Consumed on an empty stomach, they may increase stomach acid production, leading to irritation of the stomach lining, resulting in a burning sensation, heartburn, or pain.
- Risk of reflux - for some people, especially those struggling with gastroesophageal reflux, tomatoes on an empty stomach may exacerbate symptoms, such as a sour taste in the mouth, burning in the esophagus, or discomfort in the chest.
- Digestive issues - when the body is not yet ready to receive food (as happens right after waking up), acidic and fibrous products can cause bloating, gas, or intestinal cramps.
When is the best time to eat tomatoes?
The best time to consume tomatoes is during meals throughout the day, when the stomach is no longer empty. Tomatoes work great as an addition to dinner, a salad for lunch, or a light dinner — as long as they are not eaten in excess and are accompanied by other, more neutral products.
