Don't nibble on apple cores when eating apples because apple cores contain small amounts
Correct answer: hydrocyanic acid, toxic
Apple nuclei contain a small amount of harmful substances , hydrocyanic acid. Hydrocyanic acid is deposited in large quantities in the body, which can cause symptoms such as dizziness, headache, and accelerated breathing rate, and may appear coma in severe cases. But don't worry too much, the hydrocyanic acid in apples is mainly found in the core, not in the pulp.
It should be reminded that when eating apples, it is customary to nibble on the core of the fruit, although it will not lead to poisoning immediately, but eating it for a long time is indeed detrimental to health.
Apple taste sweet and delicious, suitable for people of all ages to use, especially children and adolescents eat more apples can improve our memory, if for the elderly, eat more apples can reduce cholesterol, thereby playing a role in lowering blood pressure and blood lipids, so eating more apples for the elderly, is also very good.
How to pick a good apple
The most important thing to buy apples is to be fresh. When buying and picking apples, look at the apple peduncle, if the apple peduncle is light green, it means that the time to pick it is not long, relatively fresh, then if the apple peduncle is yellow or black, and it means that it is an apple that has been picked down for a long time. In addition, if the skin of the apple has become wrinkled, it is not fresh, and it is recommended not to buy it.
Many apples in the growth process, excessive use of oxytocin, erythrin, bulking hormone, or excessive use of preservatives in storage, and even the use of colorants, waxing, bleaching dyeing, etc. in the sale, in order to meet the consumer's "look for fruit" psychology, these toxic fruits have become a serious threat to people's health. The danger of "poisonous apples": puffin, erythropotenin color, preservatives to preserve freshness. Excessive use of bulking hormone, erythrobin, and preservatives can harm the liver. Retail fruit sellers will also give apples industrial paraffin wax in order to retain moisture, and the fruit is bright and selling.
Whether apples are sweet or not is also an important factor in our selection of apples. When buying apples, measure the weight of the apples by hand, the lighter apples have less moisture, eat more cotton, the sugar is higher, the heavier ones will be more crispy to eat, and the moisture will be more sufficient.
