Is fruit juice as magical as we think?

Fruit juice provides many vitamins and minerals and is easy to absorb, suitable for busy people who are lazy to eat. Many people wonder between eating whole fruit or just drinking juice, which is better?

To answer the question of whether fruit juice is good for the digestive system, we must determine what substances are in it.

In addition to the peel and seeds, oranges and tangerines provide water, fructose, vitamins B and C, iron, and protein. Some fruits such as avocado and durian also contain fat.

When drinking juice, we drink the water and the characteristic smell of that fruit, fructose, a little vitamin, but the starch, fat, fiber, and protein in the pulp and meat of that fruit are not present.

Regular fruit juices do not make the digestive system better or worse. Of course, drinking juice makes the digestive system easier to handle instead of having to chew fruits. But I believe that working is good. Moreover, some people with digestive problems find drinking fruit juice "slightly" harmful even though it does not make the digestive system worse. For example, drinking fruits with high concentrations of vitamin C will irritate the stomach, make it more uncomfortable, and more painful, especially for people with reflux or stomach ulcers.

Many people ask me what time of day is best to eat fruit or drink juice? As I said above, fruit or fruit juice is also food, in addition to water, it also contains sugar, protein, fat, vitamins... Our body will "distribute" the path of substances from food intake.

Therefore, there is no reason to prescribe that you eat meat at the main meal and then drink fruit juice. Because meat, fish, rice, soup or fruit all contain enough nutrients, the problem is that the proportions are different for each dish. Therefore, in theory, we combine them to suit the taste, it is impossible to eat sour soup and drink lemon juice, it will not be delicious.

I support choosing fruits and juices as desserts, used during meals, the body will automatically classify and metabolize. Outside of main meals, when thirsty, we can cut fruits into small pieces or drinkjuicealso ok, no need to eat at any time.

Many people wonder how long after processing and juicing fruit, they can store it in the refrigerator to preserve vitamins and ensure safety?

In my opinion, the length of time the juice is kept in the refrigerator is not a matter of days, but rather the fear of bacterial contamination. Water-soluble vitamins are easily damaged when cooked, but less damaged when refrigerated. However, some vitamins can precipitate, such as vitamin C, which makes it difficult for the drinker to absorb.

Preserving in the refrigerator helps prevent juice from spoiling. Because in normal climate and weather conditions, fruit has full nutrition, but when cut, especially fruits with high starch and sugar content, bacteria and fungi ferment very strongly, so they are easily spoiled. Therefore, putting juice and cut fruit in a cold environment to help reduce fermentation and spoilage of food, is not meaningful in preserving vitamins.

Many people idolize fruit juice. I affirm that fruit juice is different from fruit, because juice is simply water, fructose and some water-soluble vitamins depending on the type. When this sugar enters the body, it needs vitamin B, C to be metabolized, while there is little of that vitamin in juice. Therefore, if you only drink juice, the body still needs to mobilize vitamin B, C from its reserves to metabolize.

Fruits and green vegetables contain a lot of fiber, which is very good for the digestive system, helps prevent constipation, intestinal tract, probiotics, reduces the risk of fatty liver, high blood fat, colon cancer... Fruit juice does not have as much fiber as eating whole oranges, guavas, tangerines, mangoes... If you find it difficult to eat fruit, blend it into a smoothie to take full advantage of the nutrients from the fruit./.
