We often hear many "fasting" taboos in our daily life, such as: "You can't drink tea, coffee, or alcohol on an empty stomach", "You can't eat bananas on an empty stomach", "You can't eat persimmons on an empty stomach"... What is the truth? Let's have a look.
Q: Can I drink tea, coffee and wine on an empty stomach?
A: Not recommended.
Drinking a large amount of strong tea and coffee on an empty stomach will lead to excessive consumption of coffee/caffeine/cause, which may lead to rapid heartbeat, chest tightness, palpitation and other discomfort; Drinking on an empty stomach is prone to hypoglycemia, causing dizziness, cold sweating and other uncomfortable symptoms.

Q: Can I eat bananas on an empty stomach?
A: As long as your kidneys are healthy, don't worry at all.
Some people said: "Eating bananas on an empty stomach will suddenly increase the magnesium in the human body and destroy the balance of magnesium and calcium in the blood of the human body, which will have an inhibitory effect on the cardiovascular system and is not conducive to health." Banana is indeed a kind of food with high potassium and magnesium content, but even if it is eaten on an empty stomach, the potassium and magnesium contained in it will enter the body slowly bit by bit, and the absorption amount is limited, so it will not enter the blood at once.
In addition, the body will also regulate itself, metabolize the excess through the kidney and skin, and maintain the balance of potassium and magnesium. For people with healthy kidneys, there is no strict upper limit on the daily intake of potassium and magnesium.
Q: Can I eat garlic and cold food on an empty stomach?

Garlic and cold food, both of which can stimulate gastrointestinal contracture, and may induce gastrointestinal diseases for a long time. Sudden cold in the stomach may also stimulate the heart.

Q: Can I eat persimmons on an empty stomach?
A: Don't worry too much.
Persimmons contain tannic acid, which does interact with stomach acid and protein in the stomach, but the key depends on the variety and maturity. As long as you don't eat undercooked persimmons or eat too much at one time, you don't have to worry about the risk of tannin.
However, for some people with low gastrointestinal function, such as middle-aged and elderly people, gastrointestinal emptying is relatively slow, so it is recommended not to eat a large number of persimmons on an empty stomach. If the persimmons bought are especially astringent, don't eat them hard. It is recommended to put them soft before eating.
Eating on an empty stomach also has a sequence.
It is suggested to eat vegetables first, then protein and rice such as meat. If you eat a lot of rice flour starch products at the beginning, it is not only easy to eat too many calories, but also easy to cause rapid rise in blood sugar and stimulate the secretion of insulin in the body.
Finally, eat fruit because it is high in sweetness and is easy to absorb monosaccharide. If it is eaten on an empty stomach, it is also easy to stimulate the rapid rise of blood sugar.
As for sweet and high-calorie foods like desserts, it is best to stay away from them when losing weight. If you want to eat them, the order must also be at the end.
