1. Juice contains much less nutrition than fruit. When fruit is pressed into juice, the pulp and membranes are removed. In this process, vitamin C is also greatly reduced, and vitamin C is something you must consume in large quantities.
If the fruit itself contains very little vitamin, such as apples, then in this process, the vitamins are almost completely removed.
2. Fruits that contain more nutrients usually produce richer juices. For example, citrus fruits. However, sometimes some nutrients are artificially added to the juice, such as vitamin C. Please read the label carefully to find out what substances are in it. Some brands of apple juice or grape juice may contain the vitamin C you need, but other brands may not have any at all.
3. The size of the container can affect the vitamin content in the juice. How is this possible? Note that vitamin C decomposes when exposed to oxygen. Juice in smaller containers is exposed to more air during and after packaging.
4. It is unnecessary to boast "100% juice". There is always something in the juice that serves as a flavoring, which usually has little nutritional value and in fact doesn't taste very good.
5. In so-called "juice foods" or "juice drinks", you won't find much fruit. The main ingredients are water and a high content of corn syrup. However, there are exceptions. Some cranberry juices are rich in vitamin C and are quite nutritious.
6. Once opened, juice begins to lose its nutritional value, so do not store it in the refrigerator for too long. The nutritional value of aseptic juices made from citrus, grapefruit, pineapple, etc., can be preserved for 7-10 days. Other low-acid juices, such as apple and grape, can be stored for a week after being opened.
Drinking juice also requires "moderation". Professionals recommend "two glasses of juice per day" as a scientific and healthy "benchmark". Drinking two glasses of juice (500ml) per day is a relatively good habit, as it can meet the body's needs for different vitamins, minerals, and dietary fiber. In recent years, the word "health" has been all the rage, and dietary health is what modern urban dwellers pay more attention to. However, many people have started to supplement their VC with juice. In fact, the VC in juice has a good effect on enhancing the body's immune defense and can improve sub-health conditions and restore physical vitality. However, drinking juice also depends on the "purity" and should not be done blindly.
Choose the right time to drink in moderation
Drinking juice also requires "moderation". Professionals recommend "two glasses of juice per day" as a scientific and healthy "benchmark". Drinking two glasses of juice (500ml) per day is a relatively good habit, as it can meet the body's needs for different vitamins, minerals, and dietary fiber without causing excessive fructose intake. In addition, people always think that unprocessed things are more natural. However, a new study by British medical scientists shows that the fiber and antioxidants in pure squeezed juice are kept very well. From the perspective of health benefits, pure juice and fruit have almost the same effect.
Juice contains a large number of trace elements needed by the human body, and these natural trace elements contain active substances. It is common in our country for people to have insufficient intake of fruits and vegetables. Drinking juice every day can just fill this gap. Therefore, as a drink suitable for all ages, from infants to the elderly, everyone can drink juice. Juice is considered a necessary supplementary food for infants over 3 months old to supplement vitamin C. Drinking juice daily for the elderly can help them stay away from Alzheimer's disease. You should also choose the right time to drink juice. The best time to drink juice is between meals or half an hour before a meal. Juice contains various organic acids, aromatic substances, and enzymes, which can stimulate appetite and aid digestion. If you can eat some fruit between breakfast and lunch, or lunch and dinner, it is very consistent with nutritional requirements.
Read the label to check "purity"
With the improvement of living quality, sweet and refreshing juice is becoming more and more popular. Many juices are labeled as "natural" or "freshly squeezed" to attract attention, making people easily associate juice with nutrition and health. The purity of bottled juice on the market varies greatly. If you look at the ingredient list, you will find that some juices are made by adding water and sugar. Experts point out that according to national standards, juice that is truly made by squeezing and separating fresh fruits without any other additives should be called "original juice", which is 100% pure juice. It does not add sugar or water and has the natural aroma of fruit. However, not every fruit is suitable for making original juice. For example, the original juice of hawthorn is too sour and the taste is too thick. After diluting with water and adding sugar, the taste is better. Therefore, juice products with more than 40% original juice are often more popular.
In juice beverage products, the pure juice content is usually only 10%-20%, which means that most of these juice beverages are water and sugar. The fruit flavor mainly comes from added fruit essences, and the nutrients are diluted 5-10 times, greatly reducing the nutritional value. Therefore, juice beverages can only be treated as sweet drinks, providing the human body mainly with sugar.
Therefore, when consumers choose juice, it is best to carefully check the product label to distinguish purity. Bottled juices usually indicate their juice content ratio on the packaging. Common types include 10% content, 30% content, and truly 100% pure juice. And fruit-flavored drinks, low-concentration juices, and 100% pure juice are completely different products. Pure juice has the nutritional content and richness of flavor closest to natural fruit, but it is also more expensive.
