Vegetables are rich in a variety of essential nutrients for the human body. However, caution must be exercised when purchasing vegetables, as improper selection can not only fail to strengthen health but also lead to poisoning and illness. Besides choosing seasonal vegetables whenever possible, experts remind us: it's best not to buy the following 6 types of vegetables.
Tomatoes that are too hard
The harder a tomato, the more plant hormones have likely been used. It's best not to buy them, or if you do, don't eat them immediately. Let them sit for two to three days to continue the ripening process until they soften naturally. By then, unhealthy ripening agents will have dissipated. Additionally, tomatoes that are red on the outside but green on the inside may have been treated with ripening agents.
Radishes or melons with cracked centers
It's best to avoid radishes or melons with cracked centers, as this could indicate severe pest infestation or an abnormal, non-natural growing process. If a cucumber you buy "grows" overnight, it has definitely been treated with a hormone-based swelling agent.
Leafy greens that are too pale
Vegetables grown in greenhouses are often much more attractive than those grown in direct sunlight, with paler leaves. However, their nutritional value cannot compare to naturally grown seasonal vegetables. Therefore, when buying leafy greens, choose the darker ones.
It's now rare to see root vegetables like radishes and lotus roots with dirt on them at the market. Vendors are blunt: "No one likes vegetables that are too dirty." The problem with washed vegetables isn't just pesticides, but bacteria. And bacteria are very difficult to remove, even with soaking in salt water or blanching.
Vegetables that smell unusual
Unlike aromatic vegetables such as cilantro and fennel, which have their own natural scents, vegetables with excessive pesticide residues or those treated with low-quality pesticides will have a pungent, unpleasant odor. You can pick them up and smell them before buying.
