What you can’t eat during fasting?

Avoid strong irritating food

Avoid eating fast foods that are too spicy, too acidic, too salty, and frozen. These foods will destroy the gastric mucosa or the intestinal wall, causing gastrointestinal cramps, colic, and gastrointestinal diseases. For women during menstruation, eating strong stimulating food on an empty stomach can also cause menstrual disorders and dysmenorrhea. So don’t add these food to your fasting diet plan.

Avoid foods with high protein content

If you eat milk, soy milk, eggs, meat and other foods with high protein content on an empty stomach, the protein will be “forced” to be converted into heat energy for consumption, and no nutritional nourishment will be achieved. In addition, in a short period of time, excessive accumulation of protein together, the protein decomposition process will produce a lot of harmful substances such as urea, ammonia, which is not good for health.

Avoid high sugar foods

Because the human body cannot secrete enough insulin to maintain the normal value of blood sugar in a short time, excessive consumption of sugar foods such as white sugar, brown sugar, snacks, sweet potatoes, etc. on an empty stomach can easily cause a sudden rise in blood sugar. Excessive consumption of sugar foods on an empty stomach can also damage the body’s acid-base balance, causing stomach upset, heartburn, and vomiting of acid water. Sugar foods should be excluded from fasting diet plan.

These 18 foods should never be eaten on an empty stomach


Contains a lot of ingredients such as pectin, persimmon phenol, soluble astringent, etc. It can chemically react with stomach acid, increase the pressure in the stomach, cause stomach expansion and stomach pain, or form stomach stones, especially when tomatoes and milk or soy milk are stirred in. This is more likely to occur when taken together.

The human body should eat some easily digestible, nutrient-rich liquid foods on an empty stomach. Tomatoes are single-nutrition and contain only vitamins, cellulose, and water. Fasting food not only hinders the absorption of the stomach, but also cannot meet the physiological needs of the body so, tomatoes should not be eaten on an empty stomach.


Milk contains a lot of high-quality protein. Drink it on an empty stomach and the he protein will be “forced” to be converted into heat energy for consumption, and no nutritional tonic effect will be achieved.

The best way to drink milk is with bread and biscuits. Or drink two hours after a meal, or drink before going to bed.

Soy milk

Drinking soybean milk on an empty stomach will also increase the GIT burden.


Drinking honey on an empty stomach can easily increase the acidity in the body. Over time, the stomach will become too acidic and gastric ulcer or duodenal ulcer will be formed. Expert reminds: honey is very time-consuming, it is recommended to drink 1.5-2 hours after a meal.

If you have a bad stomach, it is best to drink honey mixed in water, otherwise it will cause diarrhea, gastroenteritis and other adverse symptoms. However, the temperature should not be too high. From a pharmacological point of view, heating honey above 67 degrees will destroy the vitamins in it and reduce its aroma, and the nutritional value will be reduced.


Contains more pectin and tannic acid. The above-mentioned substances react with stomach acid to form a gel block that is difficult to dissolve and easily form stomach stones. It causes nausea, vomiting, gastric ulcer, and even gastric perforation. 

Cold drink

Drinking various frozen foods in an empty state will stimulate gastrointestinal contractures, and over time will lead to disorders of various enzymatic chemical reactions and induce gastrointestinal diseases. Drinking cold drinks during menstruation can also cause menstrual disorders.


There is a large amount of magnesium element in bananas. Magnesium is a sensitive element that affects heart function and has an inhibitory effect on CVS. Eating bananas on an empty stomach will suddenly increase the magnesium in the human body and destroy the magnesium-calcium balance in the human blood, which will have an inhibitory effect on the cardiovascular system and is not conducive to health.


Contains a large amount of organic acids, fruit acids, maslinic acid, citric acid, etc… If eaten on an empty stomach, the stomach acid will increase sharply, resulting in the  adverse stimulation to the gastric mucosa, causing the stomach to swell. If eaten on an empty stomach, it will increase hunger and the stomach pain.


Sugar is a kind of food that is easily digested and absorbed. If you eat a lot of sugar on an empty stomach, the human body cannot secrete enough insulin to maintain the normal value of blood sugar in a short time, so that the sudden rise of blood sugar is easy to cause eye diseases. Sugar is an acidic food. Eating sugar on an empty stomach will also destroy the acid-base balance of the body and the balance of various microorganisms, which is harmful to health.


Drinking yogurt on an empty stomach will weaken the health care effect of yogurt, and drinking it two hours after a meal or before going to bed has both nourishing health care, promoting digestion, and laxative effects.

Drinking yogurt on an empty stomach or excessively will increase the concentration of stomach acid, affecting appetite and digestive function, so avoid adding it your fasting diet plan. It is also incorrect to use yogurt to give medicines, because antibiotics can kill live lactic acid bacteria .In addition, yogurt cannot be heated to drink because yogurt contains live lactic acid bacteria, if heated, the live lactic acid bacteria will be killed, thus losing the health care effect.


Eating garlic on an empty stomach will cause strong stimulation to the gastric mucosa and intestinal wall, causing gastrointestinal cramps and cramps, affecting gastrointestinal digestion.


Drinking on an empty stomach can easily irritate the gastric mucosa, causing gastritis and gastric ulcers. The human body will be prone to hypoglycemia, and then dizziness, cold sweats, palpitations. Severe cases lead to hypoglycemia, coma and even death.


Drinking tea on an empty stomach will dilute the gastric juice, reduce digestive function, and will also cause “tea drunk” manifested by panic, dizziness, limb weakness, gastrointestinal discomfort, hunger in the abdomen, etc.

Once tea drunk occurs, a piece of sugar or a drinking sugar water can make the symptoms disappear. Fluoride accumulation in the body may cause intestinal diseases and affect kidney function.


It contains a lot of pectin and tannic acid, which can combine with stomach acid in the human body and form lumps in stomach. In particular, it is unwise to eat it before going to bed. People with chronic gastrointestinal diseases should not eat it.


Vitamins are not food, but if they are eaten on an empty stomach, they will be excreted in the feces before the body can absorb them. Fat-soluble vitamins such as vitamin A can only be absorbed by the gastrointestinal mucosa when dissolved in fat, and should be eaten after meals to be more completely absorbed by the body.


The proteolytic enzymes contained in it are quite strong. Eating on an empty stomach can hurt the stomach. 


Litchi has a high sugar content. Eating on an empty stomach can irritate the gastric mucosa, causing stomach pain and bloating. Moreover, eating too much fresh lychee on an empty stomach will cause “hypertonic coma” due to the sudden infiltration of excessive high sugar in the body.

Sweet potato

Sweet potatoes contain tannic acid and colloid, which will stimulate the stomach to secrete more stomach acid, causing heartburn and other discomforts.
