Extended data:
1, pay attention to choose the freshest nuts. In summer, the temperature is high and the air is humid, so nuts are particularly prone to oxidative rancidity. This is because the higher the temperature, the faster the oxidation reaction; At the same time, when the humidity is high, the moisture absorption of nuts is not only beneficial to the oxidation reaction, but also to the propagation of mold. Not to mention that the nutritional value of oxidized nuts is greatly reduced, they also produce toxic and harmful fat oxidation products, which become the source of "free radicals" to promote human aging. Nuts with mold are more likely to bring highly toxic mycotoxins, such as aflatoxin.
2, buy nuts in summer, don't buy too much at a time. After you buy it, put it in a closed jar while it is dry, and take out a handful to eat every day. On days when the air humidity is particularly high, it is best not to put nuts outside, because the humidity will be absorbed in one day. When purchasing, priority should be given to products taken out of vacuum sealed bags or products with intact shells. The risk of oxidative deterioration of this product is relatively small. Smell the smell carefully. If it tastes bad, don't buy it even if it's not "spicy".
