10 Mistakes in Eating Vegetables
Vegetables are a common sight in daily life and an indispensable part of our regular diet. Vegetables provide the human body with a variety of vitamins and minerals, which are essential for our health. However, eating vegetables also requires the right methods; otherwise, their nutritional value will be lost, and it's as if you ate them in vain. You must pay attention to these 10 common mistakes in eating vegetables. Eating vegetables the wrong way is like eating garbage! Avoid these 10 mistakes in eating vegetables!
Mistake One: Cutting Before Washing
Nowadays, most people choose to cut vegetables before washing them, believing that washing first might not get them clean enough. But did you know that many nutrients and beneficial substances in vegetables are water-soluble? When vegetables are cut into small pieces, these nutrients can leach out into the water during washing. This means we fail to achieve our goal of supplementing the body's nutritional elements. The correct method is to wash, then cut, and then cook. This way, nutrients are less likely to be lost.
Mistake Two: Squeezing Out the Vegetable Juice
When making fillings for dishes like wontons or buns, some vegetables need to be finely chopped, which releases a lot of juice. Some people squeeze out this juice for easier shaping or filling, but this is not a scientific approach. This practice discards about 70% of the vitamins and minerals in the vegetables. The correct method is to chop and mix the vegetables with ingredients like dried tofu, mushrooms, or meat. This allows the vegetable juice to seep into the other fillings, making the buns more delicious while retaining the nutrients for the body to absorb.
Mistake Three: Long-Term Storage of Vegetables
Storing vegetables for a long time causes fresh vegetables to wilt. Wilted vegetables not only taste bad, but most of their Vitamin C is also destroyed. The harmless nitrates in vegetables can be converted into nitrites. Nitrites can turn normal hemoglobin into methemoglobin, which cannot carry oxygen. In severe cases, this can cause symptoms like cyanosis of the nails and lips, or even the whole body, along with shortness of breath. Therefore, for your own health and safety, it's best to eat vegetables as fresh as possible.
Mistake Four: Improper Refrigeration
In hot weather, many people store their vegetables in the refrigerator. However, the ideal storage temperature for most vegetables is 3°C-10°C. Cucumbers, for example, should not be stored below 10°C. If kept in a refrigerator at around 4°C, a cucumber's skin will darken, its body will become soft, and a transparent, gel-like liquid will be visible after cutting. By then, the cucumber's flavor will be completely gone.
Mistake Five: Blindly Eating Vegetables Raw
In the summer heat, people's appetites can decrease, and sometimes they just eat some raw vegetables. However, some vegetables are naturally toxic and must be cooked to destroy their toxins, such as sword beans, green beans, potatoes, and bean sprouts. Vegetables that can be eaten raw must be non-toxic and uncontaminated, such as varieties with a good texture like radishes, tomatoes, and cucumbers. However, the vast majority of vegetables on the market today have been sprayed with pesticides. Although people are accustomed to soaking them before washing, this only removes about 30% of the pesticides. Eating such vegetables raw can harm your health. Therefore, it's best to avoid eating vegetables raw, even those that are typically safe to eat raw.
Mistake Six: Cooking for Too Long
Some vegetables contain Vitamin C, which is easily oxidized and decomposed by heat and should not be cooked for extended periods. Even when stir-fried over high heat or briefly heated with a lid on, some of these nutrients are lost. If cooked for a long time, even more Vitamin C is destroyed, meaning very little is left for the body to absorb.
Mistake Seven: Eating Leftovers
Thrifty people might eat leftover food from the previous meal, but by then, the nutritional value of the dish is almost gone. Measurements show that stir-fried green vegetables lose 20% of their Vitamin C after 15 minutes, 30% after 30 minutes, and 50% after one hour. Furthermore, leftover food is prone to spoilage and can easily cause food poisoning. It's best to cook and eat food immediately for both hygiene and nutrition.
Mistake Eight: Using Too Much Oil
Many people believe that a dish won't be tasty without enough oil, so they use a lot. However, just like animal fats, every gram of vegetable oil provides 9 kilocalories of energy. Consuming too much can lead to obesity, or high blood lipids, and cardiovascular diseases due to excessive calorie intake. Therefore, oil should be used in moderation. The recommended daily intake is 25 grams per person, not exceeding 30 grams.
Mistake Nine: Discarding the Vegetable Broth
When cooking, about 30%-70% of the Vitamin C and other water-soluble nutrients can dissolve into the broth. If the vegetables were blanched before cooking to remove oxalic acid, nitrites, and pesticides, and if a minimal amount of oil and salt was used during stir-frying, then drinking the broth is harmless.
Mistake Ten: Eating Too Much
Vegetables shouldn't be eaten in excess because most are difficult to digest, especially those high in crude fiber like bamboo shoots, celery, and broad beans. Large quantities can aggravate gastrointestinal conditions, trigger gastric bleeding or esophageal variceal bleeding in patients with cirrhosis, and interfere with the absorption of calcium and zinc, particularly in pregnant women and children in their developmental stages. The protein in most vegetables is "incomplete protein," lacking many essential amino acids the human body needs. To lose weight, if someone stops eating adequate amounts of high-quality animal protein and its fat-soluble vitamins (A, D, etc.) for a long time, they are prone to malnutrition. The recommended daily intake of vegetables is 300-500 grams; it should not be exceeded.
The 10 mistakes in eating vegetables are something you cannot ignore. Eating vegetables incorrectly is like eating garbage; the nutrition isn't absorbed, and the vegetables provide no benefit for supplementing the body's nutritional elements. Therefore, you must avoid these 10 common mistakes in eating vegetables.
