What are the nutritional differences among fruits, dried fruits, and preserved fruits?

Most fresh fruits contain about 85%moisture and are an important source of vitamins(vitamin C,carotenoids,and B vitamins),minerals(potassium,magnesium,calcium),and dietary fiber(cellulose,hemicellulose,and pectin)in the diet,and are nutrient rich.From the point of view that fruits contain rich dietary fiber,dietary fiber can promote intestinal peristalsis in the intestinal tract,especially fruits contain more pectin.This soluble dietary fiber can reduce cholesterol,help prevent atherosclerosis,and can combine with harmful lead in the intestinal tract to promote its excretion from the body.The advantages of fresh fruits are incomparable to dried and preserved fruits.

Dried fruits are made by dehydrating fresh fruits.After being processed and dried,fruits suffer from severe water loss,and the loss of various vitamins,especially vitamin C,makes them far inferior in terms of nutrition compared to fruits.If we have to make a choice between fresh fruits and dried fruits,we should not hesitate to choose fresh fruits.

Dried fruits are usually made from fruit pulp,which is soaked in sugar and typically requires a 65%sugar solution.They have a crystal clear appearance.Because sugar solution has a preservative effect,it is generally not necessary to add preservatives.However,there are also some cases where the use of preserved fruit sugar is reduced and the use of sweeteners is increased,which saves costs but reduces the preservative effect.Therefore,it is necessary to add an appropriate amount of preservatives to prevent corrosion.In addition,in order to make the preserved fruits more beautiful,the manufacturer will add some pigments.Just looking at the above,its nutritional value is greatly discounted.Preserved fruit almost contains no vitamin C.More importantly,because it contains high sugar,children,the elderly,obese people and diabetics should avoid overeating.

Among fruits,dried fruits,and preserved fruits,fruits have the highest nutritional value.In addition to the inherent nutritional characteristics of fresh fruits,the short storage period of fruits is also an advantage for the human body.That is,fruits are enjoyed even when they are still fresh,and their freshness cannot be compared to dried and preserved fruits.So,fruit products cannot replace fresh fruits.

If it is inconvenient to carry fruits during travel,you can choose dried fruits in moderation as a substitute.During the processing of dried fruits,apart from the loss of some moisture and water-soluble vitamins during heating,there is almost no loss of protein,fiber,minerals,etc.,and the taste is sweeter than fresh fruits.However,this sweetness is not due to the addition of sugar and sweeteners,but because the nutrients and sugar content of the fruit are concentrated after dehydration,making it more sugar dense.

Of course,eating dried fruits is beneficial for health,and it also depends on how much you eat.Because dried fruits are foods with a sugar content of about 70%and high in calories,strict limits should be imposed.Eat 1 to 2 times a day,a small handful(about 15g)each time is enough,and after eating it,you should lose a few bites of the staple food to avoid overeating carbohydrates throughout the day.
