Hot foods & beverages are bad for digestion & health

Consuming hot foods and beverages can be dangerous. They shock the digestive system, inhibit nutrient absorption, and above all, increase the risk of developing gastric and esophageal cancer!

Hot foods & beverages may increase the risk of Gastric cancer!

Eating hot foods or drinking hot beverages may increase the risk of developing of gastric cancer.

Actually, beverages and foods reach the gastric tract only a few seconds after ingestion. Gastric mucosa can’t protect the stomach effectively against high temperatures of food or liquids.[1]

For instance, drinking warm tea (50oC or 122 F) is much safer, as compared to drinking hot tea (60oC or 140 F). Hot foods or beverages may increase the risk of stomach and other cancers by up to 3 times.

On the other hand, people who prefer eating warm foods have about 80% lower risk of developing gastric cancer, as compared to those who regularly eat very hot meals!

Hot meals may increase the risk of Esophageal cancer

Moreover, eating hot foods and drinking hot beverages has been linked to increased risk of esophageal cancer.[2,3,4]

In fact, high temperature of tea, water, and food can significantly increase the risk of esophageal squamous cell carcinoma by more than 2-fold. Most noteworthy, regular drinking of “burning hot” tea can increase the risk of esophageal cancer up to 4-fold.[1]

Esophageal cancer is one of the most common malignant tumors! Also, it’s one of the leading causes of cancer death. Furthermore, it has a poor prognosis!

Other common causes of esophageal cancer are high intake of alcohol, smoking, poor diet, and high consumption of pickled vegetables.[5]

Hot foods are harder to digest

Additionally, you should avoid eating hot foods. Especially if you have digestion issues.

Actually, food temperature plays a key role in gastric emptying. Hot meals are emptied from the stomach faster than warm meals, or meals at room temperature.[6]

Practically, a pretty hot meal (60oC or 140F) can significantly accelerate gastric emptying, as compared to a warm (37oC or 100F) meal.

Furthermore, we can tolerate hot food better than hot beverages, although they cool down more slowly during the transit to the stomach. It needs 5-30 min for the temperature of ingested food to reach the temperature of the body.

Last, but not least, even pretty cold meals (4oC or 39F) accelerate gastric emptying, as compared to meals at body temperature. But, cold meals or beverages at 12oC (54F) don’t have any significant negative effect on digestion.

Therefore, you better have warm meals, or meals at room temperature for better digestion. On the contrary, you should avoid pretty hot, or pretty cold meals and beverages! Extreme food temperatures shock the digestive system. They may even inhibit nutrient absorption.

Hence, you better wait a few minutes before start eating a really hot meal.
