Vegetables are an indispensable part of our meals, providing our bodies with various vitamins and trace elements. However, vegetables available today come with various problems. Purchasing vegetables requires skill to select healthy ones.
Supermarket Vegetable Buying Guide
Point One: Understand Food Labels
Based on cultivation methods and quality certifications, vegetables can be categorized into four types: conventional vegetables, pollution-free vegetables, green food vegetables, and organic vegetables. Among these, organic vegetables are grown without any synthetic substances, green food vegetables are grown without any moderately or highly toxic substances, and pollution-free vegetables are guaranteed not to exceed pesticide residue limits. To determine the category of a vegetable, look for the corresponding quality certification label, not just whether it has plastic wrap. Vegetables without plastic wrap can be purchased with confidence if you know the brand and origin and they appear fresh.
Point Two: Understand Dark Green Leafy Vegetables
Dark green leafy vegetables, which have deep green leaves and are primarily consumed for their stems and leaves, offer the highest nutritional value. Examples include spinach, bok choy, napa cabbage, crown daisy, and kale. Chinese cabbage and cabbage do not count because their leaves are too light, meaning their nutrient content does not meet the standards for dark green leafy vegetables. Some nutrient-rich, dark green flower stalk vegetables, such as broccoli and rapeseed stalks, are also considered dark green leafy vegetables.
When selecting vegetables, pay attention to the following points:
(1) Do not buy vegetables with abnormal colors. Fresh vegetables are not always the more vibrant the better. For example, when buying cherry radishes, check if the color is rubbing off. Be cautious if dried green beans have a greener color than others.
(2) Do not buy vegetables with abnormal shapes. Unfresh vegetables may have withered, dried, damaged, diseased, or insect-damaged abnormalities. Some vegetables may grow into畸形 (abnormal shapes) due to the use of hormonal substances.
(3) Do not buy vegetables with abnormal odors. To make some vegetables look better, unscrupulous vendors may soak them in chemical agents such as sulfur or nitrates. These substances have a strange odor and are not easily washed off.
When selecting vegetables, you should pay attention to the following four points:
First, look at the color. Each vegetable variety has its own inherent color and luster, which indicates its maturity and freshness.
Second, smell the odor. Most vegetables have a fresh, sweet, or pungent aroma and should not have a rotten or other strange smell.
Third, taste the flavor. Most vegetables have a mild, sweet, sour, or refreshing taste, while a few have a special pungent, sour, or bitter taste.
Fourth, check the shape. Most vegetables should be fresh. Withered, dried, damaged, discolored, diseased, or insect-eaten vegetables are considered abnormal. Some vegetables may also grow into畸形 (abnormal shapes) due to the use of hormonal substances.
Selecting Specific Vegetables:
Cucumbers: Cucumbers that are larger at the front and longer at the back contain a lot of hormones. Avoid cucumbers that are too dark green. Choose ones with uniform thickness.
Tomatoes: Do not buy tomatoes with a pointed top (a sign of hormones) or a uniformly red color. It is better to choose heavier tomatoes with a slightly greenish bottom.
Chives: It is best to buy chives with some yellow leaves and about seven leaves, as more leaves indicate a sufficient growth period. Do not buy chives with thick, white roots.
Cilantro: Do not buy cilantro without a strong aroma or with thick roots.
Additionally, when buying vegetables, it is best to choose affordable vegetables, as they are the healthiest. Vegetables that are consistently available are less likely to have problems. Have you learned these tips?
