1, common mistakes in diet and health preservation
1. Fresh vegetables are healthier than frozen vegetables.
If it refers to fresh vegetables just picked from vegetable fields, there is no problem with this statement. But in fact, most of the vegetables we eat are not so fresh, usually stored for a few days, and vitamins are gradually lost during storage. On the contrary, vegetables frozen at ultra-low temperature can retain more vitamins, because quick freezing after picking can prevent the loss of vitamins.
It is absolutely safe to drink mineral water.
Many people say that mineral water is rich in minerals and is more beneficial to human body. However, mineral water may also be polluted by harmful substances (such as mercury and cadmium) in the land. Recently, Dutch scientists analyzed 68 different brands of bottled mineral water produced in 16 countries, and found that mineral water is more susceptible to the pollution of dangerous microorganisms and bacteria, which contains more pathogenic microorganisms than expected. Although these bacteria may not pose a great threat to healthy people, bacteria in bottled mineral water may pose a considerable danger to people with weak immunity.
Drinking coffee is harmful to human health.
Coffee can easily lead to the loss of calcium in the body, but as long as milk is added to coffee, this deficiency can be made up. In fact, coffee is good for people. It can excite brain cells and refresh the brain. If you feel sleepy after getting up in the morning, have a cup of coffee and your mind will clear up immediately. As long as drinking coffee is not excessive and hidden, adding milk before drinking will not endanger human health.
4. Brown bread is whole wheat bread.
People who pay attention to healthy eating are often confused by the color of food. Black bread is considered as a food with high health and nutritional value. As everyone knows, it is only the food coloring added by the baker when baking bread that makes black bread more attractive to buy. Therefore, black bread is not equal to whole wheat bread. It is best to read the logo clearly when buying whole wheat bread.
Bread and butter is healthier than French fries.
Once upon a time, people knew that French fries in fast food were high in calories, so they chose bread slices that looked healthier. But in order to make slices of bread taste better, many people spread butter on them when eating. In fact, compared with French fries, buttered bread slices have little difference in oil content, but almost the same contents of starch, protein and minerals. And relatively speaking, French fries contain more vitamin C, so bread and butter is not healthier than French fries.
6. Eating assorted cereals for breakfast is more resistant to hunger than bread.
Assorted cereal contains diced fruit, walnuts, raisins and other foods, and milk is added, which seems to be more abundant, but in fact it contains about the same calories as bread slices with jam. But people who eat assorted cereals usually have low blood sugar content, and the higher the sugar content, the less likely it is to make people feel hungry. Therefore, in fact, eating bread and jam is more resistant to hunger.
7. Glucose can keep people in a good state.
Although the "lightning energy" provided by glucose can make people clear-headed and energetic in a short time, this energy will be consumed quickly and people will even feel hungrier than before.
8. Fruits that are not sprayed with pesticides need not be washed.
Even green fruits should be carefully washed with water before eating. Eggs on the peel of fruits (such as strawberries and apples) are invisible. If fruit is eaten without washing, it is easy to be infected by bacteria.
9. Sweeteners help to lose weight
Many people know that drinking soup is easy to get fat, so using sweeteners instead of sugar can help us lose weight. But research shows that all sweeteners (especially Tang Jing) will accelerate insulin secretion, which will make you more dependent on sugar.
10, salad is very beneficial to human health.
Probably because of the low calorie, salads are favored by many people. Salad contains as much as 80% water, but in fact, the nutrients that the human body takes from salad are also very low. Not only that, most women should not eat too much salad. Because women's physique is usually cold, eating too much salad can easily lead to poor metabolism, poor blood circulation, bad menstruation, dull skin and even wrinkles. In addition, the nitrate content of many vegetables is also high, mainly from the fertilizer for growing vegetables, and its potential harm should not be underestimated.
1 1. Eating at night will ruin your good figure.
If this view is correct, then 99% people on the earth will become fat. In fact, only when you eat too much at night will you get fat. If you don't eat too many calories at night, you won't be overweight. However, if you want to stay, eat too late, or have the habit of taking supper, it will really increase the burden on your stomach and easily lead to sleep disorders.
12. Butter contains more calories than margarine.
Butter and margarine have the same calorie content. In fact, some margarine products are not lower in calories than ordinary butter, and their unsaturated fatty acid content is higher, which is more likely to lead to an increase in cholesterol levels in the body!
13, dark eggs have higher nutritional value than light eggs.
Dark color is often synonymous with high health and nutritional value, but the color of eggshell is only related to the variety of hen. The nutritional value of eggs depends entirely on the health status of hens and the quality of daily feed.
14. Enzymes in tropical fruits help to lose weight.
If so, that would be great. We only need to eat pineapple and papaya to lose weight. But in fact, the enzymes contained in tropical fruits can support protein's digestion, so that food can be better absorbed by the human body, but the body fat will not be burned. So slimming can't be achieved by enzymes.
15, honey is low in calories and helps to lose weight?
If you want honey to lose weight, then your hopes will often fail. In fact,100g honey contains 303 calories, while100g soup contains 399 calories. The former has only slightly lower calories than the latter. But judging from the contents of potassium, zinc and copper, the nutritional value of honey is higher than that of sugar.
16, eating potatoes is easy to get fat.
Many people regard potatoes as fattening foods, but they are not. Potatoes contain starch, but its water content is as high as 70%, the real starch content is only 20%, and it also contains dietary fiber that can produce satiety, so it is not easy to get fat when replacing staple food, and it also has the effect of losing weight! Potatoes are regarded as fattening food because of improper traditional cooking methods, and good potatoes are made into French fries and chips. A medium-sized baked potato without oil has only a few thousand calories, while the calories of French fries can be as high as 200 kilocalories or more. What makes people fat is not the potato itself, but the fat it absorbs. Anyone who has cooked beef with potatoes knows that potatoes have a strong oil absorption.
17, brown sugar is more beneficial than white sugar.
Brown sugar and white sugar are both extracted from sugar cane or sugar beet. The production process of brown sugar is slightly simpler than that of white sugar, which contains more glucose and cellulose, and releases energy faster and has higher absorption and utilization rate. However, brown sugar contains almost the same sugar and calories as white sugar. Moreover, the taste of brown sugar is not as sweet as white sugar, so people will naturally put more when drinking tea and coffee, so in fact, brown sugar is sometimes more dangerous than white sugar.
18, raw vegetables are healthier.
Many vegetables are really healthier when eaten raw, because they can best retain the nutrients in them. But raw food is not suitable for all vegetables, such as potatoes, beans, eggplant, etc. These vegetables contain toxic substances and must be cooked before eating. Carrots are rich in vitamin A, but only when people eat carrots and consume fat can they get enough vitamin A from them.
19, drinking can warm up.
Although people will feel warm after drinking a glass of wine, it is only an illusion. People's body temperature actually falls instead of rising. Because the tiny blood vessels under the skin expand rapidly because of drinking, the blood cools rapidly because of the surface expansion, and the body temperature also drops.
2. Daily habits of health preservation
1, slow health in the morning: get up slowly, drink slowly.
It takes three minutes to get up slowly. In the supine state, keep your eyes open and adapt to the alternating process from sleep to wake up. At this time, you can rub your hands and "dry your face" 1 minute. Then, sit up slowly in a semi-recumbent position and comb your hair with your fingers 100 times for 2-3 minutes. Then move your feet to the bed and sit still for 2-3 minutes. In the meantime, slowly practice deep breathing.
It is also important to drink water slowly. After a night of metabolism and water evaporation, you will get thirsty in the morning. At this time, if you drink a lot of water, it is easy to bring too much burden to your heart. The correct way is to pour a cup of warm water, first take a sip to moisten your mouth, then swallow it slowly, and then drink it in small sips, drinking 250-300 ml.
2. Exercise in the morning: Exercise more and do Sudoku.
From 9 am to noon 1, it is the most energetic and energetic time of the day. At this prime time, you should exercise at least 1 hour and use your brain for a quarter of an hour.
It is beneficial for the elderly to exercise at 9- 1 1 and 3-5 pm (when the weather is particularly hot, it should be chosen before 9 am and after 5 pm). 1 hour exercise, you can use 15 minutes to warm up, 30 minutes to exercise, and finally 15 minutes to stretch. After exercise, you can massage your waist and legs, sit down and lift your legs 10 minutes to relax and eliminate edema. People who don't exercise all the time can seize the scattered time to exercise. The so-called brain refers to positive thinking. No matter retired people or office workers, they can spare a quarter of an hour to do a few brain teasers or Sudoku during the break to really mobilize the potential of their brains.
3. Run healthy in the afternoon: drink plenty of water and twist your waist.
In the afternoon, the body needs to consume a lot of food for lunch, and the small intestine absorbs almost all the nutrients in the food and sends them to the blood. At this time, you must drink a glass of water to dilute the blood and protect the blood vessels.
Sedentary people should get up and twist their waist at this time, massage their abdomen in circles, and let the water they drink moisten their intestines and stomach to prevent constipation. Besides letting water enter the body, let it nourish every corner of the body. You can wipe your face with a warm wet towel to wake up the fatigue in the afternoon.
4, hot health at night: drink some wine, soak your hands and feet.
Between 7: 00 pm and 9: 00 pm, it is the time when the body gradually begins to get tired, but the focus of health care at this time is to let the tired body gradually stretch out.
A drink before bed is a good way to keep fit. However, it should be noted that it is best to choose a low-alcohol wine and drink two drinks. Alcohol can accelerate blood circulation and promote sleep.
In addition, the evening in winter is also very suitable for bathing. Soak in warm water at 37-39℃ for about 20 minutes to calm your body and mind. In addition, it can be replaced by three steps: hot compress on face, soaking hands and soaking feet. First, prepare a pot of hot water, soak the hot towel, wring it out, apply it to your face 1 min, and repeat the above steps three times after the towel cools. Then immerse your hands in hot water 1 min. Pour another bucket of hot water and soak your feet and calves 15 minutes. Then you can achieve the same relaxation effect as bathing.
5, free-range at night: I want to be happy and relaxed.
The arrival of night means the end of the day. Making good use of the most free time in a day will make family life full of warmth and humor, and also help to eliminate the tension at work. At this time, you can get together with your family, talk about happy things, ask about the life of the elderly and the study of your children, and tell everyone about your troubles. Don't hold it in your heart. In a word, a day is just a hurdle. Only by clearing away the garbage in your heart can you have a stable sleep.
In addition, you can massage before going to bed. Pressing Baihui point, Yongquan point and Zusanli point 30 times each can effectively help sleep. Especially, it is not only a good way to relax the body, but also a good way to enhance feelings and happiness by massaging each other between husband and wife to relieve the feet, calves and back that are too tired to stand and sit during the day.
