★ Milk

There is a saying that milk contains a lot of protein. Although it can replenish energy for the body in a short period of time, if you consume too much milk on an empty stomach, not only will the protein in it not be absorbed by the body, but it will also cause flatulence and discomfort in the digestive system. .

In fact, there is no problem for healthy people to drink milk on an empty stomach. After milk enters the human body, the lactose and fat in the milk will be decomposed first to provide heat for the body, followed by protein. Under normal circumstances, protein is not used as a source of heat, so it is not There is no chance that it will not be absorbed by the body.

Some people experience gastrointestinal cramps or diarrhea when drinking milk on an empty stomach. The reason may be lactose intolerance. Without other foods to dilute it, drinking milk on an empty stomach can aggravate the symptoms of lactose intolerance. It is recommended that friends with this situation drink it after meals.

★ Banana

Some people believe that bananas contain a lot of magnesium and potassium. Eating them on an empty stomach will cause the levels of magnesium and potassium in the blood to rise sharply and increase the load on the heart.

First of all, the mineral content in bananas is not that much. The magnesium content in 100g of bananas is 43mg, and the daily recommended amount of magnesium is 350mg/day. Secondly, even on an empty stomach, magnesium and potassium will be slowly absorbed by the body. Excess magnesium and potassium ions will be excreted along with urine, kidneys, and skin metabolism, and will not directly flow from blood vessels to the heart. Therefore, eating 1 to 2 bananas on an empty stomach in moderation is generally not a problem.

However, it should also be noted that people with impaired kidney function may develop hyperkalemia due to impaired potassium excretion function if they eat a lot of bananas or eat them on an empty stomach; people with gastric ulcers and gastritis may develop uncomfortable symptoms such as heartburn and acid reflux; diabetes Because patients need to control blood sugar, the intake of bananas must also be determined based on blood sugar conditions.

In addition, bananas can promote gastrointestinal peristalsis. Eating them on an empty stomach will cause the gastrointestinal tract to work in advance, so it is not recommended to eat them on an empty stomach for a long time.

★ persimmon

Can you eat persimmons? Will eating persimmons on an empty stomach cause stones? The discussion about persimmons has always attracted much attention. The reason is that the high content of tannic acid in persimmons may cause stones. The large amount of pectin contained in persimmons will also increase the pressure in the stomach, causing gastric distension and stomach pain.

In fact, not all persimmons have high tannic acid content. The tannic acid content of persimmons after natural ripening is very low. Whether eaten on an empty stomach or not, it will not cause stones. For people with healthy gastrointestinal health, there is no problem in eating a small amount of ripe, skinless persimmons on an empty stomach.

Immature persimmons contain a large amount of tannic acid and pectin. If eaten in large quantities on an empty stomach, tannic acid can easily react with gastric acid to form hard lumps that are difficult to dissolve. In severe cases, it can cause stomach pain, nausea and vomiting.

★ Hawthorn

Some people believe that eating sour foods on an empty stomach will aggravate gastric acidity and be detrimental to health. It is true that fruits contain organic acids, fruit acids and other acidic components, but the pH value of human gastric acid is lower than these organic acids, so for ordinary people, eating appropriately on an empty stomach will not cause discomfort.

People suffering from stomach problems (such as gastritis and gastric ulcers) already have excessive gastric acid secretion. It is indeed not suitable to eat overly acidic fruits such as hawthorns and oranges on an empty stomach to avoid aggravating the condition. It is not advisable to eat too much hawthorn at one time, 3 to 5 pieces a day is appropriate.

★Fans

Previously, a topic related to fans of a certain brand not being able to eat on an empty stomach became a hot search topic. Peng Xichun, deputy chief physician of the Nutrition Department of Changsha Central Hospital in Hunan Province, said in an interview with the media that most of the raw materials for vermicelli are starch, that is, sugar. There is no problem if you take a small amount on an empty stomach. If you take a large amount, the sugar will stimulate the secretion of gastric acid. In mild cases, acid reflux and gastric bloating may occur, and in severe cases, nausea and vomiting may occur.

In addition, ordinary biological starch is divided into amylose and amylopectin. Most of the vermicelli is amylose. Foods containing amylose are less likely to stimulate blood sugar and insulin, and have a strong feeling of satiety. Although eating foods with higher amylose content is less likely to gain weight, it is also less likely to be broken down and digested.

Therefore, if you encounter people who have a fragile gastrointestinal tract, are prone to indigestion, or even have gastric ulcers or related chronic diseases, it is generally recommended not to eat vermicelli on an empty stomach. You should also pay attention to the amount when eating, and a small amount is better.

★ sweet potato

Sweet potatoes should not be eaten on an empty stomach, and are mainly targeted at people with gastrointestinal problems such as hyperacidity, gastric ulcers, or bloating. If these people eat sweet potatoes on an empty stomach, they are prone to acid reflux and heartburn. For people with normal gastric function, it doesn’t matter if they eat a moderate amount of sweet potatoes on an empty stomach.

What to eat on an empty stomach is related to gastrointestinal function

In fact, there is no final conclusion on what you can and cannot eat on an empty stomach, but it varies from person to person.

★ Coffee, strong tea

The caffeine contained in coffee and tea can stimulate gastric acid secretion, especially strong tea with high caffeine content. Regular drinking on an empty stomach can stimulate the gastrointestinal digestive system.

★ Lychee

During the lychee season, “lychee disease” often occurs. It is an acute neurological disease, and many people will suffer from hypoglycemia and epilepsy.

Hypoglycemic acid A and methylenecyclopropylglycine contained in lychees will inhibit certain metabolic enzymes after entering the human body, causing problems in the conversion of other energy substances into sugar. After the glycogen in the human body is depleted, energy will appear in the brain. Substance deficiency, resulting in hypoglycemic encephalopathy.

The glycogen storage in the human body is already very low when fasting. Eating lychees will aggravate hypoglycemia. Especially sensitive people, such as children, the elderly, or those prone to hypoglycemia, should not eat lychees on an empty stomach.

 ★ Chocolate, sugary drinks

It is best not to eat a lot of sugary substances on an empty stomach, such as sweet chocolate, milk tea, drinks, etc. Sugar can be absorbed by the body immediately without digestion and enter the blood directly, causing the body’s blood sugar level to significantly increase, increasing the burden on the pancreas, and thus damaging organ function.

If hypoglycemia occurs, you can quickly eat some high-sugar foods to relieve it. Generally speaking, it is best not to consume chocolate or sugary drinks on an empty stomach.
