Introduction: Everyone eats vegetables, but most people overlook their nutritional value. Habits like storing vegetables for too long or not eating cooked dishes immediately can cause a significant loss of nutrients. How many of the following 9 misconceptions apply to you?
I. Storing Vegetables for Too Long
Office workers often prefer to do a big weekly shopping trip and store the vegetables at home to eat slowly. While this saves time and is convenient, it's important to know that vegetables lose a large amount of nutrients for each day they are stored. For example, spinach loses up to 84% of its vitamin C after just one day at room temperature (20°C). Therefore, you should try to minimize the storage time for vegetables. If you must store them, choose a dry, well-ventilated, and light-proof place.
II. Throwing Away the Part with the Most Vitamins
Some habitual vegetable preparation methods also affect their nutrient content. For instance, some people discard the bean sprouts to eat only the shoots, but the cotyledons actually contain 2-3 times more vitamin C than the shoots. Another example is squeezing out the juice when making dumpling filling, which can cause a loss of over 70% of the vitamins. The correct method is to mix the chopped vegetables with oil first, then add salt and seasonings. This "oil-coating-vegetable" technique prevents the dumpling filling from becoming too soupy.
III. Stir-frying with Low Heat
Vitamins C and B1 are sensitive to heat. Therefore, avoid stir-frying with low heat for a long time; instead, use high heat. Additionally, adding a little vinegar helps preserve the vitamins.
Some vegetables are even more suitable for eating raw in salads, such as cucumbers and tomatoes.
IV. Not Eating Cooked Dishes Immediately
Many people like to leave cooked food in the pot to keep it warm or in a thermal container to eat later. This also leads to a significant loss of nutrients. Imagine how wasteful it would be to painstakingly prepare a meal only for it to lose all its nutritional value because you didn't eat it right away.
V. Eating Vegetables but Not the Soup
When stir-frying, a large amount of nutrients from the vegetables dissolve into the cooking liquid. It's a real shame not to drink the soup.
VI. Cutting Vegetables Before Washing Them
Cooks in canteens often cut vegetables first and then rinse them all together together. Many people don't think twice about this, but it actually causes a large amount of vitamins to be washed away into the water.
VII. Preferring Stir-fried Vegetables
Many people on a diet believe that stir-frying vegetables with meat can reduce fat intake. In fact, vegetables absorb oil more easily.
VIII. Being a Vegetarian
These days, there are more and more vegetarians. While this is beneficial for preventing arteriosclerosis, an all-vegetarian diet is not entirely correct. First, the human body needs to ingest a certain amount of cholesterol from meat daily, and a moderate amount of cholesterol is even beneficial for cancer prevention. Second, a purely vegetarian diet can lead to insufficient protein intake, which may easily cause digestive tract tumors. Third, it can result in a lack of vitamin B2. Fourth, because vegetables are generally low in zinc, vegetarians are also prone to severe zinc deficiency. A better approach is to combine foods according to your body's needs. This way, you can achieve the benefits of a vegetarian diet while avoiding the potential harm it may cause.
IX. Eating Raw Vegetables Without Washing Them Thoroughly
Vegetable contamination is becoming increasingly serious, with residues of various pesticides and parasitic bacteria. Therefore, it is best to wash raw vegetables thoroughly and peel them before eating.
