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, but they are usually stored for a few days, and vitamins will gradually lose during storage. On the contrary, vegetables frozen at ultra-low temperature can retain more vitamins, because freezing vegetables immediately after picking can prevent the loss of vitamins.
2. lie. 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.
But mineral water may also be polluted by harmful substances in the land, such as mercury and cadmium. It is found that mineral water is more easily polluted by dangerous microorganisms and bacteria, and there are more pathogenic microorganisms than expected. Although these bacteria may not pose a great threat to healthy people, bacteria in bottled mineral water may pose considerable danger to people with weak immunity.
3. Lies. Drinking coffee is harmful to human health.
Coffee can easily lead to the loss of calcium in the body, but adding milk to coffee can make up for this deficiency. In fact, coffee is good for people. It can stimulate brain cells and has a refreshing effect. After getting up in the morning, if you feel sleepy and confused, have a cup of coffee and your mind will clear up immediately. As long as you don't drink too much coffee, don't hide it, and drink it with milk, it's not harmful to your health.
4. Brown bread is whole wheat bread.
People who pay attention to healthy eating are often confused by the color of food: brown bread is considered to be a food with higher health and nutritional value. As everyone knows, this is just the food pigment added by the baker when baking bread, which makes the brown bread more attractive to buy. So black bread is not equal to whole wheat bread. When you buy whole wheat bread, you'd better read the label.
Bread and butter is healthier than French fries.
Everyone knows that French fries in fast food are high in calories, so they choose sliced bread that looks healthier. But in order to make bread slices taste better, many people will spread butter on them. 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 hungrier than sliced bread.
The mixed grain contains diced fruit, walnuts, raisins and other foods, and milk is also added. It looks richer, but in fact, it contains almost as many calories as sliced bread with jam. But people who eat whole grains usually have low blood sugar content, and the higher the sugar content, the less likely it is to make people feel hungry. So, in fact, eating jam bread is more hungry.
7. Lying. Glucose can keep people in good condition.
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. lies. Fruits that have not been sprayed with pesticides need not be washed.
Even green fruits should be carefully washed with water before eating. Eggs (such as strawberries and apples) on the skin of fruits are invisible. If fruit is eaten without washing, it is easy to be infected by bacteria.
9. Sweeteners help you lose weight.
Many people know that eating ponds 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) can accelerate insulin secretion, so you will be more dependent on sugar.
Lie 10。 Salad is extremely beneficial to human health.
Probably because salad is low in calories, it is favored by many people. Salad contains as much as 80% water, but in fact, the human body's intake of nutrients from salad is 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, irregular 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 can not be ignored.
Lie 1 1。 Eating at night will ruin your health.
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, staying at home, eating too late, or having the habit of taking supper will really increase the burden on the stomach and easily lead to sleep disorders.
Lie 12。 Butter contains more calories than margarine.
Butter and margarine have the same calorie content. In fact, some margarine products are not only lower in calories than ordinary butter, but also higher in unsaturated fatty acids, which is more likely to lead to higher cholesterol levels in the body!
Lie 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.
Lie 14。 Enzymes in tropical fruits help to lose weight.
If so, how nice it would be! 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 fat in the body will not be burned. So slimming is not something that enzymes can do.
Lie 15。 Honey is low in calories and helps to lose weight?
If you pin your hopes of losing weight on honey, your hopes will often fail. In fact,100g honey contains 303 calories, while100g Tang contains 399 calories. The former is only slightly lower than the latter. However, the nutritional value of honey is higher than that of sugar in the content of potassium, zinc and copper.
Lie 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. Therefore, replacing the staple food with it is not only difficult to gain weight, but also has the effect of losing weight! Potatoes are regarded as fattening food because of improper traditional cooking methods. 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 after being made into French fries can reach more than 200 kilocalories. 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 ability to absorb oil.
Lie 17。 Brown sugar is more beneficial than 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, releases energy faster and has higher absorption and utilization rate. However, brown sugar contains almost the same sugar and calories as white sugar. And the taste of brown sugar is not as sweet as white sugar, so people naturally drink more tea and coffee, so in fact, brown sugar is sometimes more dangerous than white sugar.
Lie 18。 Vegetables are healthier when eaten raw.
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 and eggplant. These vegetables all contain toxic substances. They must be cooked to eat. Carrots are rich in vitamin A, but the human body can only get enough vitamin A by ingesting fat at the same time.
Lie 19。 Drinking can warm you up.
After drinking a glass of wine, people will feel warm all over, but this is just an illusion. In fact, people's body temperature drops instead of rising. Because the tiny blood vessels under the skin expand rapidly due to drinking, the blood cools rapidly due to surface expansion, and the body temperature drops accordingly.
