What is the nutritional value of jam?

Jam tastes very soft, sweet and sour. Many people like to eat it. Jam is very rich in nutrients, and it contains nutrients from various fruits. Jam is very rich in cellulose and mineral elements. In addition, it also contains rich ingredients that can play an antioxidant role, such as flavonoids, anthocyanins, etc. A very typical nutrient in jam is pectin, which is actually a soft dietary fiber. This soft dietary fiber has a stronger ability to absorb water than ordinary crude fiber. And it will not have the same harmful effect on the intestines as crude fiber. Jam contains a natural fruit acid, which can enhance the secretion of digestive juices, help the human body digest and absorb, and promote appetite. Another function of jam is that it can increase the degree of pigmentation, which has a certain auxiliary effect on the treatment of iron deficiency anemia.

How to preserve jam?

Making food into jam is a way of preserving food. As long as we strictly follow the operating steps to make jam and bottle it, we can put the jam directly in the cupboard. From this point of view, freezing does not seem to be necessary, but when preserving some candied fruits or jams with very low sugar content, because they cannot be sterilized at high temperature, or the amount is very small and can be eaten quickly, we can choose to freeze them.

If you want to preserve jam or candied fruit with a very low sugar content for a long time, or simply want to solve the problem of preserving food, high temperature sterilization is the ideal choice.

Is jam high in calories?

Among these jams, peanut butter, chocolate jam and milk jam have higher calories, while fruits such as strawberries, oranges, grapes, etc. have relatively lower calories. Sugar-free jams are also available in the market, and the calories of this type of jam are even lower. For example, 2 porcelain spoons of strawberry jam have 100 calories, while a large plate of strawberries would have 100 calories. However, 2 porcelain spoons of strawberry jam have very poor satiety and the rate of increasing blood sugar is also very fast. It is easy to get hungry after eating, while a large plate of strawberries has a much stronger satiety. (For example, a small cake has 100 calories, while 100 calories of rice is half a bowl.) In addition, many people cannot stop eating once they start. It is not just a matter of eating 1 or 2 spoons, but even half a bottle or a whole bottle, resulting in a high energy level just from eating this thing. Energy also increases and decreases. If a negative energy balance is maintained, it will definitely lead to eating less other recommended foods such as lean meat, tofu, fish and shrimp, so it is likely that the balance of nutrients will be difficult to achieve.
