These are the foods you should avoid on an empty stomach
There are many products that are consumed instinctively every morning and that may be behind some digestive discomfort that you may feel after having breakfast. These are some of the foods that you should be careful with if you want to eat them on an empty stomach:
Tomato and cucumber: the first is a vegetable full of health benefits.

The second is also full of healthy properties, ranging from the famous effects on the skin to the less widespread anti-inflammatory properties. However, it is better to try to avoid them at breakfast because, according to Carrera, “to the already high acidity of tomatoes, the high insoluble fiber content of these vegetables is added, which stimulates acid secretion.” Carbonated drinks: it is not It may be a very widespread custom to have breakfast with soda or sparkling water, but it has its followers. Drinking too many carbonated drinks “irritates the gastric mucosa and increases the production of hydrochloric acid in the stomach,” explained the specialist.

The Spanish Food Composition Database (BEDCA) recognized its high carbohydrate and fiber content, but its amount of potassium (350 mg in 100 grams), magnesium (38 mg) and sodium (28 mg) stands out above all. , necessary to maintain heart health. Precisely this richness in these minerals is what leads the CMED expert to advise not eating it on an empty stomach to “prevent a large amount of potassium from being absorbed, which can generate cardiac arrhythmias.”
