I believe that fasting can not eat fruit, can not drink milk ……, many people have heard, in order to answer the long-standing doubts in everyone’s mind, the following, we have invited Sichuan University Hospital clinical nutrition nutritionist to speak about, is not these things can not eat fasting, in the end what can not eat fasting.

01 You say “fasting”, empty very casual!

If you think about it, isn’t there a standard for what you call “fasting”?

After eating at 7:00 p.m., by 7:00 a.m. the next morning, 12 hours without food, counting as fasting.

It was 2:00 a.m. in the evening when we finished our snack, and at 7:00 a.m. we weren’t even hungry, still considered an empty stomach.

After breakfast at 8:00 a.m., by 12:00 p.m., after 4 hours of drinking only water, I counted fasting.

After 1:00 noon, we ate a bottle of milk tea, two oranges, a bag of beef jerky, and two slices of tofu jerky at 6:00 p.m. for five hours, which is considered an empty stomach.

Even if you just want to eat it purely with your mouth, it counts as fasting, it’s really too casual!

02 Medical fasting, which must be 8 hours or more without food or drink

Fasting refers to the empty state of the stomach, here to talk about the concept of gastric emptying.

Gastric emptying refers to the process of food from the stomach into the duodenum, the general food into the stomach about 5 minutes after the start of gastric emptying, emptying speed for carbohydrates> protein> fat, which is why the son only eat porridge, steamed bread is not hungry, and you stuffy a few lumps of meat is very useful reasons.

The gastric emptying of mixed foods takes about 4 to 6 hours. Clinical fasting requirements are more stringent, to eat and drink 6 to 8 hours before you can, is not eat + do not drink ha, drink a few sips of coke, milk tea kind of do not count!

So true fasting usually only happens the morning after the first day’s dinner, no snacking before bed, and no midnight snacking!

Sense 1: Drinking milk and soy milk on an empty stomach is not nutritious.

The reason for this is that milk and soymilk have high nutritional value, but if you drink it on an empty stomach, the nutrients will be wasted because the empty stomach cannot absorb them. The reality is that every mouthful of milk and soymilk that goes into the stomach is not wasted!

Milk and soymilk contain 3% to 4% protein and a small amount of carbohydrates and fats, so the nutritional value is guaranteed, but the key is that our stomachs are not the leaky ladle of a hotpot, so if we don’t put something in first, the milk and soymilk will leak out directly from our mouths. The structure of the digestive tract of a healthy human body has the physiological function of controlling the absorption of nutrients, and even liquid food will be absorbed as fully as possible. So how can drinking milk and soy milk on an empty stomach be a waste?

If there are people who say that milk and soymilk must be eaten together with cakes, buns, and fritters to be good for you, that’s just to say that if you eat a lot of food, it will take longer for your stomach to empty and you’ll be hungrier!

Nutritionist: Drinking milk and soymilk on an empty stomach has no effect on the absorption of nutrients!

SAY 2 Drinking milk on an empty stomach is easy to cause diarrhea

It is true that a small percentage of people feel bloated, sick to their stomach, or even have diarrhea after drinking milk, but these symptoms are not caused by drinking milk on an empty stomach, but because they are lactose intolerant themselves. This group of people, regardless of whether you have an empty stomach or not, can easily feel nausea, vomiting, and diarrhea if you smother a glass of milk.

For people with mild symptoms of lactose intolerance, you can drink milk in small amounts and multiple times, and eat steamed buns, bread and other foods while drinking milk, and the symptoms will be reduced, or even activated after a period of time to activate lactase activity, you can return to the state of being able to drink milk on an empty stomach. But people with real lactoprotein allergies should remember that they should not drink milk and eat dairy products in any state.

Diarrhea has nothing to do with drinking milk on an empty stomach.

The first thing you need to know about yogurt is that it’s too “sour” on an empty stomach and can hurt your stomach.

It is believed that in the fasting state with a lot of stomach acid, yogurt and then drink into the stomach, not only will irritate the gastrointestinal tract, making the stomach acid more acidic and hurt the stomach, but also too much stomach acid may destroy the lactic acid bacteria in the yogurt. Without lactic acid bacteria, yogurt is equal to a cup of drink, you must first eat something into the stomach to cushion the yogurt before it can play its proper role.

And the truth is, people think of their stomachs as too delicate!

First, the pH value of yogurt is generally between 4.00~4.25, and the pH value of stomach acid is 0.9~1.5, so yogurt is simply far worse than stomach acid, and drinking it into the stomach on an empty stomach will not make the stomach acid become more acidic, and there is no such thing as stomach damage.

Second, the lactobacillus in yogurt is a really good thing. Not only does it allow the lactose in milk to break down into lactic acid, which is easier for the body to absorb when lactic acid and calcium are combined, but it also creates an acidic environment in the gastrointestinal tract, which aids in the absorption of iron. While stomach acid destroys a large number of lactic acid bacteria, there are so many lactic acid bacteria in a bottle of yogurt that stomach acid can’t destroy them all.

nutritionist Most yogurt is not yet put in sugar, acid what acid!

Theory 1 Eating bananas on an empty stomach is bad for the heart and kidneys, and also easy to get diarrhea.

The reason for this is that many people believe that bananas are rich in magnesium, potassium and other elements that can affect the heart and kidneys if eaten on an empty stomach.

The reasoning really seems a bit “reasonable”, but it is also unreliable.

First of all, bananas contain more magnesium, potassium and other elements, but it does not mean that the fasting eat into than not fasting eat to absorb more ah, and even if the absorption is also slowly absorbed, must not instantly biu a sound through the blood vessels to follow the blood to the heart.

Secondly, eating bananas for diarrhea this thing we have said before, in view of the time is a little long ago to nag again, although bananas contain dietary fiber to promote intestinal peristalsis, but in fact, bananas for laxatives to promote digestion of this thing, really useless!

1) Bananas don’t have much dietary fiber

Even if you eat 2 bananas a day, the amount of dietary fiber you get in is less than the amount of dietary fiber you get from 2 dates.

Some bananas don’t help with bowel movements, they help with diarrhea!

Yes, if ripe bananas are even a little bit of a laxative, raw bananas are the complete opposite.

Because raw bananas contain a lot of tannins, too much of which can cause constipation, raw bananas are perfect for diarrhea sufferers.

Doctor, people usually buy ripe bananas, but how can we eat raw bananas? “

A: In reality, many people buy ripe bananas that have been ripened. Since most bananas are produced in the tropics, they are picked when they are still raw and shipped across the country or even around the world to be ripened and then ripened. Even though the bananas are ripe, the tannins in the flesh are still present, so eating them won’t help your bowel movements.

Nutritionist: If you still have diarrhea even after eating fake – ripe bananas on an empty stomach, you may want to consider whether your last meal was clean!

Myth 2 Eating persimmons on an empty stomach will cause stones and stomach pains.

There are a lot of people who have heard this argument, and there are a lot of arguments on the Internet.

It is believed that the tannin content in persimmons is so high that it is easier to absorb on an empty stomach, and that the protein in the stomach, together with the persimmon pulp that is eaten in the stomach, can easily turn into stones and even cause stomach pain.

This seemingly professional statement is actually problematic.

It is true that eating large amounts of persimmons with high tannin content can cause stones, but not all persimmons have high tannin content, especially the sweet and tasty ones that you like to eat and are willing to buy are usually ripe persimmons.

The most common type of persimmon is the unripe one, which has a high tannin content, and it’s a good idea to wait for it to ripen for a while before eating it.

Nutritionist: It’s not like there’s anyone else to take it from you, wait until the persimmon is ripe before you eat it!

SAY 3 Eating tomatoes on an empty stomach hurts your stomach?

If it wasn’t for the professionals, who made such a great deal of headway, it almost would have been a disaster again!

First, pectin is a dietary fiber commonly found in the cell walls of plants, and is present in many fruits, but human digestive juices cannot break down the cell walls of plants, so it passes directly through the stomach and small intestine, where it is fermented by bacteria and can promote intestinal peristalsis.

The content of pectin in tomatoes is about 0.4%, which is very low compared to other fruits and vegetables, the content of apples (with skin) is about 0.78%, and the content of carrots is up to about 2.04%. The actual actual time of the day, the actual time of the day, the actual time of the day, the actual time of the day.

Nutritionist: If eating tomatoes on an empty stomach hurts your stomach, then the white rabbit eating so many carrots on an empty stomach wouldn’t have already had a stomach ulcer and perforation!

The stomach relies on its ability to secrete gastric juice to digest food, and gastric acid in gastric juice is a strong acid, too much secretion will have an erosive effect on the mucous membrane of the stomach and duodenum, and damage the mucous membrane, which will induce or aggravate ulcerative diseases; and too little secretion of gastric acid may cause bloating, diarrhea and other indigestion.

In life, there are indeed some foods that will make the gastric juices react and cause stomach discomfort, especially for certain groups of people such as those with weak digestive function, those with digestive diseases, and those with diabetes.

01 Foods with strong stimulating properties

The number one representative is chili peppers, whether it is chili noodles or millet chili, these spicy ingredients will stimulate the secretion of a large amount of stomach acid, damage the gastric mucosa, for people who have their own stomach disease is not recommended to eat often, and not recommended to eat on an empty stomach.

Of course, most people have to and their own fault, Mo have to go fasting bite a few bites of raw pepper, but those spicy bars, spicy noodles, spicy jumping chicken wings …… usually do not eat spicy people really want to eat less, must eat it is best to pad something first.

02 Over-iced/over-heated food

The first thing you need to do is to take a look at the newest products that are available on the market, such as the newest products, the newest ones, and the newest ones. So, on an empty stomach, drink less ice-cold Kool-Aid (at room temperature), less non-hot hot pot or skewers (at dong ha sesame oil), and less boiled coffee, tea, and soup (at dong ha) to protect these organs!

03 Coffee, strong tea, wine

I know that after reading the previous article you will want to follow up to ask: “iced, hot drink can not, that room temperature coffee, tea on an empty stomach can not drink? “

No matter what the temperature of coffee and tea, the caffeine contained in it will stimulate the secretion of stomach acid, while the high content of caffeine in tea, will also stimulate the secretion of stomach acid, so for gastric ulcer patients, it is best not to drink on an empty stomach. And for people who don’t feel uncomfortable drinking it, drinking it on an empty stomach is not a big problem, the most panic.

In addition, there is a drink – wine, is not suitable for fasting drink, because the alcohol will cause a strong stimulation of the stomach, causing gastric acid secretion, we really want to drink it, remember to drink before the pad to some peanuts, pasta!

04 Lychee

According to a number of cases and studies found that every litchi season, there will be “death after eating litchi” reports, the most likely cause of the current analysis is hypoglycemic encephalopathy The cause. The study found that some of the cases occurred in the absence of dinner, although not 100% medically clear why, but in view of the very high sweetness of lychee, children, the elderly, people with abnormal blood sugar, especially not recommended to eat on an empty stomach.
