Iced fruit not nutrition nutritious easy discount King

• Fruits in the most vulnerable to the effects of nutrients is the temperature of vitamin c, refrigerated longer, the more vitamin C loss

● Edible ice fruit will stimulate intestinal peristalsis, making and intestines, causing diarrhoea

Modern life busy, no time to stroll around the market every day.

Therefore, nowadays many families like to supermarket one-time purchase a food storage in the fridge, fruit is one of the most extensive collections of one of the "." Moreover, many people find it after the fruit in the refrigerator before eating ice, eating more happier. But you may not know, fruit if put in the fridge too long, or improper storage of temperature settings, will result in the loss of fruit nutrition, but also may cause health problems.

"Delicate" vitamin C are most vulnerable to erosion

Most of the nutrients in fruits such as glucose, fructose, minerals are relatively stable, even if ice is not significantly affected, but most of the vitamins are not stable, the most "delicate" is vitamin C.

Fruit contains large amounts of vitamin C oxidase, this enzyme will function with vitamin C to destroy vitamin c activity.

Fresh fruit in cold storage place for some time, vitamin C oxidase and the oxygen in the air, causing the interaction of vitamin c content gradually to reduce, and along with refrigerated longer the loss. Like peaches in 7.7 ° c 1 day in the store, the vitamin c content is ever left 90% to 70% in 5 days, 7 days after loss of vitamin C by almost half. In addition, the fruit of flavonoids, anthocyanins, antioxidant during placement is the role of the PPO, etc. and have varying degrees of damage.

Control of refrigeration temperature effectively reduce nutrient losses

The loss of vitamins in fruits and cold temperature too.

Refrigerator temperature distribution is not uniform (3 ° c to 10 ° c), and in summer the actual temperature in the fridge will be slightly higher. Lower refrigeration temperature, can reduce vitamin c oxidase activity, thereby reducing the loss of vitamin C. If the fruit is placed on the 2 ° c to 5 ° c, the vitamin C of save than 6 ° c to 10 ° c higher.

However, if the storage temperature is below 0 ° c, causing the formation of ice crystals, frozen fruit ice thawed when moisture loss, this time not only various kinds of water-soluble vitamins such as vitamin C, b vitamins, folic acid, etc. will be destroyed, some minerals such as potassium, phosphorus, calcium, etc. will be lost.

Therefore, we recommend that you put a thermometer inside the fridge to learn about the cool temperatures so that timely adjustment.

Edible improper bowel "injured"

Edible iced fruit will stimulate intestinal peristalsis, making and intestines, causing diarrhea; make a sharp contraction in the gastrointestinal tract blood vessel, blood flow is reduced, affect the secretion of digestive fluid; cause gastrointestinal spastic contraction and abdominal pain, dyspepsia.

Some fruit rich in water, it is easy to grow bacteria and fungi, such as cut watermelon.

Fruit surface if pathogenic bacteria in the fridge contaminated food is likely to lead to bacterial infection, acute gastroenteritis, the most common symptoms are abdominal pain, vomiting, diarrhea.

The elderly, children, pregnant women and other groups reduce due to resistance, gastrointestinal delicate, reduced resistance to infection and other reasons, to avoid for intestinal significantly boost of iced fruit.

Gastrointestinal function is not good, if suffering from stomach ulcer, chronic gastritis, enteritis crowd to avoid iced fruit, to avoid aggravating condition.

Iced fruit

Eating three note

Note 1:

Consumption of time.

Try not to just eat or when eating ice fruit on an empty stomach, can after 1 ~ 2 hours after eating.

Note 2:

Each dosage should not be too much to not cause gastrointestinal discomfort.

Such as watermelon each consumption do not exceed 500 grams, grape, peach around 15 satellites do not exceed 1, Strawberry 10 ~ 15.

Note 3:

If one did not eat watermelon, iced after next time before eating surface should be cut off before consumption, other store in the refrigerator of the fruit also to wash again before consumption.

Iced fruit

Because of the "fruit" vary

Fruit in the refrigerator cold storage time should not be too long, and try to take advantage of fresh food.

In addition, not every kind of fruit are fit into the refrigerator and freshness. Some fruit born of "afraid of the cold", primarily native to tropical fruit such as bananas, mango, papaya,

Put in the refrigerator it will be "disaster", causing skin spots or on up into the dark brown, damaged fruit flavor and nutrition.
