Core tip: Many people often encounter many confusions when buying vegetables at the market: what kind of vegetables are fresh and healthy. Potatoes should be chosen without broken skin, and ginger should not be too white. Did you know all this?
Tomato:
For raw eating, buy pink ones; for cooked eating, buy bright red ones
The market mainly has bright red tomatoes and pink tomatoes. "Bright red tomatoes have higher sugar and acid content, and are more flavorful. Pink tomatoes have lower sugar and acid content, and are milder." Wei Zifu, a nutrition therapy manager from the Chinese Medical Doctor Association, introduced that when buying tomatoes at the market, if you want to eat them raw, buy pink tomatoes which have a milder sour taste and are better for raw eating. If you want to cook them, you should try to buy bright red tomatoes.
"At the same time, pay attention that some tomatoes are artificially ripened." Wei Zifu reminded, do not buy deformed tomatoes with 'tips'. In addition, to determine if a tomato is artificially ripened, you can break it open. Artificially ripened tomatoes often have no seeds or the seeds are green, and the pulp has little juice.
Potato:
The skin should be intact and clean
Many people say that as long as potatoes have not sprouted, they are fine. In fact, this is not the case. Wei Zifu introduced that potatoes should be chosen without broken skin, "The skin must be dry, not with water blisters, otherwise the storage time is short and the texture is not good."
If you find the potato skin has turned green? Wei Zifu introduced that a green potato is a sign of the presence of toxic alkaloids, which can cause poisoning if eaten, so do not choose green potatoes.
Ginger:
Don't choose the ones that are too white
Wei Zifu introduced that when buying ginger, you must clearly see if it has been bleached with sulfur. Because once ginger is fumigated with sulfur, its appearance becomes very white and tender, looking very good, and the skin has already fallen off.
Wei Zifu said that industrial sulfur contains harmful substances such as lead, sulfur, and arsenic, which adhere to the ginger during the fumigation process. After consumption, it can harm the respiratory tract, and in severe cases, it can even directly damage the liver and kidneys.
"So when choosing ginger, don't pick the ones with too clean an appearance; a smooth surface is fine. Try to buy ginger that is firm in texture, not soft or mushy, and with fresh, tender buds." Wei Zifu suggested.
