Long-term storage of vegetables
Fresh green vegetables, bought and stored at home, will slowly lose some vitamins. If spinach is left at 20 degrees Celsius for a day, the loss of vitamin C is 84%. To preserve vegetables, store in a dark, ventilated, dry place.
Discarded the most abundant part of vitamins
For example, bean sprouts, someone eats only the buds and loses the watercress. In fact, watercress contains 2-3 times more vitamin c than bud. Then, when the vegetable dumplings are stuffed, the juice is squeezed out and the vitamin is lost more than 70%. The correct method is to chop the dishes and mix them with oil, then add salt and seasonings.
Cooking with low heat
Vitamin c, b1 are afraid of heat, afraid of cooking, according to the determination of the fire fry dishes, vitamin c loss of only 17%, if fried and then boiled, the food will lose 59% of vitamin c. Therefore, stir-fried vegetables need to be prosperous. The dishes that are fried out are not only delicious in color, but also have less nutritional loss in the dishes. Adding a little vinegar when cooking, it is also conducive to the preservation of vitamins. There are also some vegetables such as cucumbers, tomatoes, etc. It is best to eat cold.
The cooked food is not eaten right away
Some people want to save time, like to burn vegetables well in advance, and then wait for people in the pot to eat or eat hot next meal. In fact, vitamin B1 in vegetables can lose 25% in the process of warming after burning. Burned cabbage can lose 20% of vitamin C if it is warm for 15 minutes, and lose 10% if it is kept for 30 minutes. If it grows to 1 hour, it will lose another 20%, if the vitamin C in vegetables loses 20% during cooking. Dissolved in vegetable soup loses 25%. If it is warmed on fire for 15 minutes, it will lose another 20%, totaling 65%. Well, we don't have much leftover vitamin c from vegetables.
Do not drink soup
Many people love to eat vegetables but do not like to drink soup. In fact, when cooking, most of the vitamins are dissolved in the soup. Take vitamin C as an example. After the Chinese cabbage is fried, 70% of the vitamin c will be dissolved in the vegetable soup. Fresh peas will be boiled in water for 3 minutes. Vitamin C will be 50% dissolved in the soup.
Cut vegetables and then rinse
When washing vegetables, if the vegetables are cut and washed, a large amount of vitamins will be lost to the water.
Prefer to eat cooking
Some people prefer to fry vegetables with meat in order to lose weight without eating fat. Recently, according to researchers, vegetables with rich water content contain cells filled with air, and cells in the meat are filled with water, so the vegetables absorb oil more easily. The oil contained in a dish is often better than a dish. Fried fish or fried ribs contain more fat.
Do not eat vegetarian
There are more and more vegetarians nowadays, which is undoubtedly beneficial to prevent arteriosclerosis. However, it is not blessing not to pay attention to collocation and blind vegetarianism. Modern science has found that vegetarians have at least four major harms: First, the lack of essential cholesterol, and the right amount of cholesterol has anti-cancer effects; Second, the lack of protein intake, which is a risk factor for digestive tract cancer; Third, riboflavin intake Insufficient dosage can lead to vitamin deficiency. Fourth, it is severely deficient in zinc. Zinc is a very important trace element that ensures the body's immune function is perfect. In general, vegetables lack zinc.
Like raw without washing
The pollution of vegetables is mostly pesticides or molds. Occurrence of pesticide poisoning in vegetables occurs. Vegetables are also the parasites of mold. Most molds are insoluble in water, and some are even safe in boiling water. It can enter the surface of vegetables a few millimeters deep. Therefore, fresh vegetables must be washed with fresh water, foaming, peeling, and some old yellow rot leaves. Do not begrudge, especially if you eat raw food, otherwise, it will cause harm to your health.
Keep in mind the nutritional knowledge of vegetables so that the vegetables you eat are healthy enough.
