Misunderstanding 1: All foods containing cereals are healthy foods
Although numerous studies have found that foods rich in cereals are effective against heart disease, cancer and many other diseases. But experts also said that only unprocessed cereals are rich in nutrients such as cellulose, vitamin E and magnesium. Once processed into flour, wheat can cause the loss of these nutrients. Harriman, head of a non-profit consumer organization in Boston, said: "Unfortunately, most of the food on the market today is only labeled with 'grain-rich'. In fact, there is not a complete grain inside." So, When purchasing such products, be sure to look carefully at the nutrition label and make sure that the grain you need is listed first or second.
Myth two: Vitamin drinks are healthy
Today's bottled water has also become a "nutrition concept stock," claiming that it is rich in various vitamins and "essentials" of Chinese herbal medicines, which is enough to see how much people care about health. However, "Prevention" magazine consultant Elizabeth Sommer advises everyone to "look at their wallets", which contain a lot of heat in the bottled water. Taking a well-known brand of beverage as an example, a whole bottle of water contains 125 calories, and the content of vitamin C is not as good as that of two strawberries. Therefore, when you are thirsty, choose pure water without calories. If necessary, it is good to eat a single compound vitamin every day.
Myth 3: Dehydrated vegetables are better than potato chips
Dehydrated vegetables are getting more and more popular, from dehydrated carrots to mushrooms and onions. But these healthy looking snacks still have a loss of nutrients. Moreover, a pack of 120 grams of dried carrots contains about 600 calories, which is comparable to potato chips. Are you surprised?
When you want to eat a small snack, choose a small nut that is rich in cellulose, unsaturated fatty acids, vitamins, and minerals, and can satisfy your desire to chew. If you want to choose absolutely healthy products, authentic vegetables are the best, carrots, celery sticks, cucumbers are all good.
Myth 4: Fruit-containing snacks are healthier
Photographs of beautifully packaged fruits, claiming that all products come from fresh fruit – even so, you can never use them as a source of daily nutrition.
"Concentrated grape juice or pear juice sounds very healthy. In fact, most of their raw materials are only fructose and water," said Professor Gail, professor of food science and human nutrition at Florida State University. "They often contain a lot of heat - almost All from the added sugar."
If such small snacks are directly used as fruit, it is better to eat less. If you want to find some quick and easy ways, perhaps bagged raisins or some other dried fruit is a good choice.
Myth 5: bottled milk is fresher
The short shelf life of milk in glass bottles has caused people to mistake it for being fresher, but it is not. Transparent packaging of milk, some nutrients will be lost. The calcium in milk is relatively stable, but vitamins and amino acids break down in the light. A Cornell University study found that when milk was packaged in transparent containers and exposed to fluorescence for 16 hours, the vitamin A content was reduced by 32%. The light also oxidizes the fat in the milk and the taste deteriorates.
It is best to drink milk in an opaque container. In this case, the nutrients in milk can be stored for more than 10 days.
Myth 6: Drinking is not good for health
More than 100 studies have confirmed that moderate drinking can reduce the incidence of heart disease by about one-third compared to those who do not drink alcohol. Drinking alcohol during a meal can slow down the increase of alcohol in the blood and accelerate the body's metabolism. All these factors can combine to relieve the increase of blood pressure. Drinking a small amount of alcoholic beverages at mealtimes has another benefit: Alcohol is a well-known ingredient that can prevent arterial embolism and heart disease, which are often prone to occur after a big meal.
Misunderstanding 7: Eat mints after meals
The cool taste of mints is suitable to ease the greasy after meals, but in fact, this will bring a lot of trouble. Research by the National Information Center for Digestive Diseases found that mint can cause a burning sensation, and it can also cause stomach fluids to flow back into the esophagus to cause a burning-like feeling. The reason is that peppermint will make the muscles of gastric cardiae relax, which will cause reflux.
If you have a feeling of heartburn, drinking a glass of plain water after a meal and then taking a walk is a good choice. Walking allows you to stay upright and use gravity to keep stomach acid from flowing back into the esophagus.
