1. Storing Vegetables for a Long Time Office workers often prefer to do a big weekly shopping and store the vegetables at home to eat slowly. Although this saves time and is convenient, it's important to know that vegetables lose a large amount of nutrients for every day they are stored. For example, under normal conditions (20°C), spinach loses up to 84% of its vitamin C content after just one day. Therefore, the storage time for vegetables should be minimized. If you must store them, choose a dry, well-ventilated, and light-protected place.
2. Discarding the Part with the Most Vitamins Some conventional vegetable processing methods also affect the nutrient content of vegetables. For instance, some people discard the bean sprouts themselves to eat only the sprouts, but in fact, the bean sprouts contain 2-3 times more vitamin C than the sprouts. 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 a little oil before adding salt and seasonings. This method, which coats the vegetables in oil, prevents the dumpling filling from becoming too soupy.
3. Stir-frying with a Small Flame Vitamins C and B1 are both heat-sensitive. Therefore, avoid stir-frying over a low flame, which simmers the food; instead, use a high flame for quick stir-frying. Additionally, adding a little vinegar helps preserve the vitamins. Some vegetables are even more suitable for eating raw, such as cucumbers and tomatoes.
4. Not Eating the Food Immediately After It's Cooked 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 become nutritionally worthless because you didn't eat it right away.
5. Eating Vegetables Without the Soup When stir-frying, a large amount of nutrients from the vegetables dissolve into the cooking liquid. Not drinking the soup would be a real waste.
6. Washing Vegetables After They Are Cut Chefs in cafeterias often cut vegetables first and then rinse them together to save time. Many people don't think twice about this, but it also causes a large amount of vitamins to be washed away into the water.
7. Preferring Stir-fried Dishes Many people on a diet believe that stir-frying vegetables with meat can reduce fat intake. In reality, vegetables more easily absorb oil.
8. Eating Only Vegetables and No Meat There are more and more vegetarians these days. Although it's beneficial for preventing arteriosclerosis, an all-vegetable diet is not entirely correct. First, the human body needs to consume 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 can easily cause digestive tract tumors. Third, it results in an insufficient intake of vitamin B2. Fourth, because vegetables are generally lacking in zinc, vegetarians can also easily become severely deficient in it. A better approach is to eat a combination of foods according to your body's needs. This way, you can get the benefits of a vegetarian diet while avoiding the potential harm to your body.
9. Eating Raw Vegetables Without Washing Them Vegetable pollution is becoming increasingly serious, with residues of various pesticides and parasitic bacteria. Therefore, it's best to wash and peel raw vegetables thoroughly.
