six questions and answers for healthy eating of fruits:
different varieties of fruit, the color will be different, such as Fuji apple is red, Wanglin apple is yellow. After bagging, the color of the fruit will be more beautiful and even, but the taste of the fruit with uneven color is not inferior to that of the beautiful fruit. From the point of view of delicacy, scented fruits are more reliable. No matter what color, fruits with rich aroma are usually the most delicious. However, in terms of nutritional value, deep color varieties are usually better than light color varieties. For example, purple black and purple red varieties have higher antioxidant substances than green and white meat varieties.
2. Judging from the taste of fruit, is the nutritional value of acid high or sweet high?
the contents of nutrients and health care ingredients of fruits have little relationship with sweetness. Generally speaking, for the same kind of fruit, the content of vitamins and antioxidants is higher in the varieties with slightly sour taste. For example, especially sweet, a little sour and astringent citrus, in which the polyphenols content is lower than slightly sour and astringent varieties. This is because most of the health care ingredients have a little unpleasant taste, either sour, or astringent, or bitter, and basically have nothing to do with sweetness. This is not to say that the fruit is not good when it is sweet. It is to say that if there is only sweet taste and no other flavor, the health value of the fruit may not be as good as that of the fruit with rich flavor.
3. Should fruit be eaten more in season?
no matter what season, eating fruit is better than not eating it. However, if possible, priority should be given to fruits in season, because the quality of fruits in season is often better than that of products out of season. For the north, there are almost no seasonal fruits before April; May is strawberry, may to June is cherry, bayberry, apricot, early peach, loquat, July to August is watermelon, melon and peach world, and litchi and longan supply. From September to October, apple, pear, Begonia, sand fruit, pomegranate, kiwi fruit and so on are listed in large quantities. There are also lots of oranges, oranges and grapefruit in the back. Some fruits ripen more than once a year, or different varieties mature in different seasons, such as mangoes and pineapples.
4. When buying fruit, should you choose a small one or a big one? Did some big ones add swelling agent?
the size of fruit is mainly controlled by variety, and it can’t be evaluated by size alone. To fully understand, you can query the relevant website to understand the main varieties of a certain fruit, with pictures or text introduction. For example, if the average weight of a certain fruit variety is 120 grams, then 100 grams or 140 grams are normal, but 180 grams is strange. For example, Fuji apple grows bigger and Gala apple grows bigger. An expert specializing in expanders told me that expanders are cytokinins, which can make the fruit grow bigger and ripen faster, but affect the sweetness and flavor, and are not conducive to storage. When buying fruits, first of all, choose the fruits of medium size among the same varieties, and do not discriminate against the small ones; Second, try the taste. If the flavor is rich, sweet and sour, you don’t have to worry about the expansion agent. The size can be adjusted manually, but the taste can’t be fake. In the market, you can ask for tasting; Go to the supermarket to buy two less first. I think it’s delicious. It’s not too late to buy more.
5. The fruit is a little bad on the surface. It’s a pity to throw it away. Can you still eat it?
fruit & lt; Bad & quot; There are several cases, some are moldy, some are soft and rotten, some are bruised and brown, some have scars or insects. If it’s a bruise, it doesn’t interfere with eating at all. Just remove a small piece of browning. Scars and worms don’t interfere with eating. Soft rotten fruit can be removed from the soft part, the rest can be eaten if there is no moldy taste, but may have the taste of alcohol fermentation, not delicious but non-toxic. If it’s mildew, be careful. Because mold may secrete toxins. If it’s just a small piece, it’s OK to cut more; If the proportion is large, it should be thrown away for the sake of insurance.
6. It seems that some fruits are not easy to keep and are easy to rot. what should we do?
the ripening of fruit needs a kind of fruit called & lt; Ethylene & quot; To start up. Some fruits are once started ripening process, just go all the way to soft rotten. These fruits, such as avocado (avocado), domestic kiwi fruit, Yantai pear and banana, must be bought rigidly. Once they mature, they soften rapidly and thoroughly. They are eaten in two days and cannot be transported or stored. When you buy this kind of fruit, you should feel it carefully. The fruit should not be bruised. After you buy them, first put them into a plastic bag without a break, and then put one or two apples, begonias, pears and other fragrant fruits, and tie up the mouth together to let the natural ripening gas released from the ripe fruits & lt; Ethylene & quot; To make a difference. After 3-5 days, gently press the base of the fruit. If it’s a little soft, it means you can eat it. Eat it in the order of softness.
