Extended information:

1. Pay attention to choosing the freshest nuts. In summer, the temperature is high and the air is humid, so nuts are particularly prone to oxidation and rancidity. This is because the higher the temperature, the faster the oxidation reaction; At the same time, when the humidity is high, after the nuts absorb moisture, it will not only be 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. And nuts with mold are more likely to bring highly toxic mycotoxins, such as aflatoxin.

2. Buy nuts in summer, don't buy too many at once. After you buy it, you should pack it in a closed jar while it is dry, and take out a handful every day to eat. On days when the air humidity is particularly high, it is best not to put nuts outside, because moisture will be absorbed in a day. When purchasing, we should give priority to products taken out of vacuum sealed bags or products with undamaged shells. The risk of oxidative deterioration of such products is relatively small. Smell the smell carefully, and if there is a stale smell, even if it is not "spicy", don't buy it.
