Do you remember the last time you cooked at home? The fast pace of society makes fewer and fewer people cook for themselves.
Many people will think, "Why do you have to cook by yourself when you are so tired every day?" Moreover, restaurants, takeaways, convenience foods and automatic food vending machines can basically meet everyone's demand for "eating", which is delicious and convenient. Besides, I have to buy food and clean up the dishes when cooking, which is really troublesome ~
But Coco wants to tell you that cooking is actually a "longevity skill".
1. People who often cook at home live longer.
A cohort study published in the journal Public Health Nutrition shows that people who love cooking live longer.
In this study, 1888 participants were followed up for ten years, and nearly half of them (43%) never cooked. 65438+ 0-2 times a week, accounting for17%; About 9% are 3-5 times a week; More than 5 times a week accounted for 3 1%.
Compared with never cooking, cooking can significantly reduce mortality, and the more frequent cooking, the lower the risk of death. Cooking more than five times a week reduces the risk of death by nearly 50%. Even if the variables such as physical function, cognitive function, economic status and marital status are adjusted, the number of cooking times is still significantly related to the reduction of mortality.
The reasons for this result are as follows:
Compared with eating at home, eating out increases the intake of high-calorie food, significantly reduces the intake of coarse grains and vegetables, significantly increases the intake of meat, and exceeds the standard of oil and salt, which increases the risk of obesity and hyperlipidemia.
② Eating out without public chopsticks is a serious problem, and the tableware is not always clean, which increases the risk of infectious diseases such as Helicobacter pylori and hepatitis A. ..
After eating, getting up and doing housework is actually an exercise. According to statistics, it takes about 136 calories to wash and clear the dishes, 200 calories to mop the floor, 250 calories to sweep the floor, and 150 ~ 200 calories to take out the garbage.
In soothing exercise, it can promote gastrointestinal peristalsis and help food digestion. On the contrary, it is more prone to abdominal obesity if you directly collapse on the sofa watching TV and playing mobile phone after meals.
The meaning of cooking is not just about eating. A study by Johns Hopkins University in the United States found that people who often cook by themselves are happier than those who don't, because the efforts made in making food increase their sense of value.
Moreover, family members eating around the table can enhance communication and feel more comfortable.
Although life is busy, we encourage everyone to cook at home more. But the kitchen is also a hidden danger place, so we should pay attention to several points in the cooking process ~
Second, do not pay attention to these points when cooking.
Increase the risk of illness
1, vegetables should not be soaked for a long time, and nutrients will be lost.
Many people are afraid that they won't be clean, and they like to soak children's vegetables in water for a while. However, this practice will lead to the loss of some water-soluble vitamins and minerals, especially the cut vegetables; Moreover, for vegetables containing nitrite (such as lettuce, radish, spinach, celery, etc. ), the activity of nitrate reductase will increase under anaerobic conditions, resulting in an increase in nitrite content.
Suggestion: Vegetables can generally be washed directly with running water. After washing, try to control the moisture and dry it before cutting. In addition, it is best to cook the cut vegetables immediately to avoid some nutrients being destroyed by oxidation.
2. It is not advisable to wash raw meat with running water, so as not to increase the risk of spreading germs.
During the transportation, storage and sale of raw meat, some bacteria and viruses may survive on the surface.
Therefore, when dealing with fresh food, it is not appropriate to wash it directly, so as not to spill it, pollute the kitchen sink, affect the tableware and other ingredients beside the sink, greatly increase the pollution range, and may cause gastrointestinal symptoms such as diarrhea and abdominal pain.
Experts suggest that fresh food should be soaked in salt water for about 10~ 15 minutes, then washed with tiny running water, and disposable gloves and masks can be worn if necessary. In addition, fresh food should be heated at high temperature before eating.
3, cut raw and cooked food chopping board should be separated, to avoid cross infection.
When cutting raw food, bacteria in the food will remain on it, and some raw food may also carry parasitic eggs. If it is used to cut cooked food again, bacteria will directly pollute cooked food with kitchen knives and chopping boards as the medium.
Moreover, even if it is "disinfected" with boiling water before use, the bacteria will not be completely eliminated.
Suggestion: It is best to prepare three chopping boards at home-one for cutting vegetables, one for cutting raw food and one for cutting cooked food.
4. Avoid cooking fumes and prevent carcinogens.
Many families have the habit of smoking in the oil pan before cooking, thinking that the oil is ripe. But in fact, when the oil smokes, the oil temperature is likely to reach above 200. Putting the food into the pot at this time will not only destroy the nutrition of the food, but also make the protein, fat and carbohydrate in the food change abnormally and produce some carcinogens.
Suggestion: In the cooking process, it is best to use hot pot and cold oil.
5. Turn on the range hood during and after cooking to protect the lungs.
Cooking oil will produce lampblack at high temperature, which contains many irritating and harmful substances. Long-term inhalation is very harmful to the body, especially to the lungs.
Studies have shown that the risk of lung cancer in middle-aged and elderly women who have been exposed to high-temperature kitchen fumes for a long time has increased by about 2 to 3 times, which is no less harmful than smoking.
Therefore, you must turn on the range hood when cooking, and let it continue to work for a period of time after frying to avoid waste gas residue. In the meantime, don't forget to open the window.
6, use less detergent to wash dishes, so as not to affect hormone secretion.
The main component of detergent is surfactant, and some surfactants contain environmental estrogen.
If the dosage is too large and it is difficult to clean, it may remain on the plate and enter the human body. If this happens for a long time, it may have an impact on female endocrine, and may also lead to a decline in the quantity and quality of male sperm. Even lead to precocious puberty in children.
Therefore, it is suggested that every time you wash the dishes, squeeze a detergent the size of 50 cents coins, dilute it before washing the dishes, and then wash it with water at least three times.
