Expert Tip: 6 Vegetables You Should Avoid Buying
Besides trying to choose seasonal vegetables, experts suggest that you should avoid buying the following 6 types:
Tomatoes that are too firm: The firmer the tomato, the more plant hormones were used. It's best not to buy them, or if you do, don't eat them right away. Let them sit for two to three days to continue the ripening process until they soften naturally. By then, any unhealthy ripening agents will have also dissipated. Additionally, tomatoes that are red on the outside but green inside may have been treated with ripening agents.
Radishes or gourds with cracked hearts: It's best not to eat radishes or gourds with cracked hearts, as they have likely suffered severe pest infestations. The cracks could also be caused by abnormal, artificial cultivation practices.
Cucumbers that grow in size: If a cucumber you buy "grows" overnight, it has definitely been treated with a hormone-based swelling agent.
Leafy green vegetables that are too pale: Vegetables grown in greenhouses are much more attractive than those grown in direct sunlight, with paler leaves. However, their nutritional value cannot compare to that of naturally grown, seasonal vegetables. Therefore, when buying leafy greens, choose the darker ones.
Vegetables that smell unusual: Unlike vegetables like cilantro or fennel that have a natural aroma, vegetables with excessive pesticide residues or those treated with low-quality pesticides will have a pungent, unpleasant smell. You can smell them before buying.
Pre-washed vegetables: It's now rare to find carrots or lotus roots with dirt on them in the market. Vendors are blunt about it: "Dirty vegetables are not in demand." The problem with pre-washed vegetables isn't pesticides, but bacteria, which are very difficult to remove, even with salt soaking or blanching.
The Difference Between Pollution-Free, Green, and Organic Vegetables
The safety level of these three concepts increases progressively.
Pollution-free vegetables: These are vegetables where the use of high-residue, high-dose pesticides is prohibited, and the products meet national food hygiene standards.
Green vegetables: This does not mean they are purely natural and pollution-free. Instead, they are vegetables where the types and amounts of pesticides used are strictly limited.
Organic vegetables: This is the highest safety level. The use of any pesticides is completely forbidden, and they are grown in a pollution-free environment.
