For professional baristas, please follow the coffee workshop (Wechat official account cafe_style)

The stay time of liquid in the stomach is very short, only a few minutes to more than ten minutes. The shorter the stay time, the less likely it is to stimulate gastric acid secretion and avoid stomach injury.

On the other hand, stomach acid is a strong acid, and its pH value (pH) is only 1 ∼ 2, so lemon juice diluted with water is "negligible" compared with stomach acid, and it is less sour by comparison, so drinking lemon juice on an empty stomach should not hurt the stomach.

Many people like to have a cup of coffee after getting up and awaken the brain with the aroma of coffee. But what should be reminded is that it is not suitable to drink coffee on an empty stomach, because caffeine can strongly stimulate acid secretion in the stomach, which really hurts the stomach.

Don't drink on an empty stomach. The nutrition of food is absorbed by the small intestine, but alcohol is absorbed from the stomach.

If you drink on an empty stomach, alcohol will come into direct contact with the gastric mucosa and be absorbed, strongly stimulating gastric acid secretion, very harmful to the stomach, and may also cause acute gastritis. Coffee and wine had better be drunk after dinner.

Can drinking lemon juice reduce gastric acid secretion?

Folk prescriptions say that people with a bad stomach can drink lemon juice to inhibit gastric acid secretion, which is not correct.

Stomach acid is a strong acid, which needs strong alkali to neutralize. For example, the composition of stomach milk tablets is sodium bicarbonate, which is a strong alkali, so there is a way to neutralize strong acid. In comparison, lemon juice is not alkaline enough to neutralize stomach acid.
