Fruits and vegetables are alive, although they are detached from where they grew, they continue to be metabolized until you either eat them or rot them completely. If we take this into account, we are much more likely to be able to store them properly.

Just as a person has his own internal clock, which divides our daily life into day and night regimes, thus affecting our metabolism, aging and many other processes, so fruits and vegetables are sensitive to light and dark.

Ignoring the fact that when you buy them, they are already torn off, it is good to know that even after that, the amount of light can affect the vitamins in them.

Initially, research was done on plants of the cruciferous family (cabbage, cauliflower, broccoli) and the end result showed that under certain conditions, although isolated, they continue to change the production of certain chemicals in their structure. It turns out that they react to darkness, to their "protective hormones" called glucosinolates.

They give a bitter taste to cabbage, horseradish, turnips, cauliflower, beets and more. When they are still in nature, this hormone protects them from animal attacks. However, when these products are already in your home, it is better to try to consume them as soon as possible, because otherwise their taste changes over time.

In laboratory tests, an experiment was made with Kupesh cabbage - half kept in the dark and the other half in the natural light cycle. In the end, it turned out that when caterpillars were released among the cabbages, there was less damage to those that were kept in natural light. The same was tried with spinach, lettuce, carrots, blueberries, sweet potatoes and zucchini and the result was the same again.

However, it is important to say that in addition to keeping caterpillars away, glucosinolates are anti-cancer compounds that remove carcinogens in the body. That is why you should not leave fruits and vegetables unused for a long time.
