Ten Lies About Diets There are many maxims of diets, familiar to most people who care about their health. However, many maxims are lies, conveying wrong ideas to people and it's time to correct them. Once people mention sugar, salt, and fat, they would say coincidentally, "don't eat too much". Is that true? Everything has its limit. As long as you don't cross it, you will not be harmed. 1. Fresh vegetables are healthier than the frozen ones. If fresh vegetables are referred to ones just picked from vegetable field, then it is right to say so. But in fact, what we eat is not that fresh, usually placed for several days and losing many vitamins. Instead, the frozen vegetables contain more vitamins as they are frozen to prevent the loss of vitamins. 2. You can totally trust on mineral water. There are many minerals which are healthy for people. But mineral water can also contain harmful substances, such as mercury and cadmium. Recently, Dutch scientists have analyzed 68 kinds of mineral water from 16 countries and found there are much more bacteria in mineral water than what we think. Though those bacteria may not cause damage, for weak people they are still dangerous. 3. It is unhealthy to drink coffee. People think drinking coffee cause the loss of calcium and so they usually pour some milk on it. In fact, coffee is healthy for people which can refresh them. When you get up, dizzy, then you can drink a cup of coffee and you feel sober. 4. It is better to eat raw vegetables because in this way, many nutrients are kept. But it is not the case for all vegetables. For example, potatoes, beans, and eggplants contain toxic substances and should be cooked for eating. Carrots are high in vitamin A, but only when they are cooked, vitamin A can be absorbed. 5. Salad is healthy because it contains low calories. Though salad contains much water, it contains few nutrients. What's more, women are not suitable for eating too much salad because most of them have a cold physique. Too much salad causes a bad metabolism, blood circulation and skin. Besides, many vegetables contain high nitrate which is very harmful. 6. Eating snacks at night can ruin your figure. If it is true, 99% of people can get fat. In fact, only when you eat too much at night, you gain weight. However, eating food too late can result in insomnia. 7. Eggs with dark color are more nutritive than those with light colors. But the color of eggs is only related to hens' breeds. The nutritive value of eggs depends on hens' sate of health and the quality of feed. 8. Honey contains low calories, helpful for losing weight. But it is not true. In fact, 100 grams honey contains 303 calories and 100 grams sugar contains 399 calories. Thus, we can see honey doesn't contain that low calories. But, honey does contain more potassium, zinc and copper. 9. Sweetener is good for losing weight. Many people know eating sugar can gain weight and thus, use sweetener to take place of sugar. But researches show that sweetener, especially saccharin, can accelerate the secretion of insulin. As a result, people turn out to depend on sugar more. 10. Drinking some wine can warm people up. But it is just an illusion. The body temperature actually decreases because capillaries under skin expand quickly.
