1, what is junk food?
According to this concept, we can easily understand why instant noodles, cola, crisp bread, French fries and various puffed snacks are called junk food.
However, it should also be noted that there are few foods that are absolutely "junk" except those with high trans fatty acids. The real junk food is related to the amount and frequency of consumption, the object of consumption and the food collocation.
For example, eating one hamburger a week will not affect your health, but three hamburgers a day are dangerous for dinner;
For people who don't have enough to eat, high-energy food can save lives, and instant noodles are also artifacts for post-earthquake disaster relief;
Instant noodles are also a good meal if eaten with a lot of fresh vegetables, eggs and other high-quality protein foods.
2. Is bread, vegetables and patties really impeccable? Bread: It is made of refined wheat flour with oil, salt and sugar, fermented and baked, and tastes good.
However, it belongs to refined carbohydrates, with few B vitamins, minerals and dietary fiber, and the postprandial blood sugar reaction is also very high. The secretion of insulin is as high and low as riding a roller coaster, and it is easy to get out of control, and then it becomes a well-known diabetic.
However, the water content in vegetables is very high, and there are few dry goods. We need at least 1 kg of colorful vegetables every day to meet our needs for these nutrients.
However, meat, especially skin and fat, contains saturated fat, which is easy to cause obesity. Eating a lot of red meat has a clear cancer risk, and it should not exceed one catty per week.
The meat pie will definitely put fat meat, otherwise it will have no soft and juicy taste at all, so that you wonder if your teeth are getting old in advance. During the production process, it will be fried or fried with oil, with high fat content, and by the way, it will also produce benzopyrene, acrylamide and other bad substances. At the same time, a lot of salt and other seasonings will be added to the meat pie during curing, and the sodium content is not low.
3. Hamburgers may not be junk food?
There are obviously vegetables providing vitamins and minerals in hamburgers, and meat as a high-quality protein, which seems to have nothing to do with junk food!
Indeed, compared with some fast food (such as braised pork mixed rice), hamburgers are really not "garbage". A standard "Golden Arch" or "Kaifeng Cuisine" hamburger has strict requirements on materials and calories, which can just meet the calorie needs of a meal. Although the nutrients are not up to standard, at least it will not make you gain weight easily.
If you scrape off the salad dressing in the hamburger and match it with a vegetable salad without salad dressing, the whole thing will be much better, and it can even be called a nutritious fast food.
4. Why are hamburgers junk food?
High calorie: In addition to the fat in the meat pie and the fat added during cooking, the salad dressing and cheese in the hamburger are also high in calories, and the total calories are high. If you eat it with cola, French fries and popcorn, the calories will be invincible.
Low nutrition: Bread is a refined carbohydrate, and there are too few vegetables and the quality is not high, which can not meet the needs of vitamins, minerals and dietary fiber for our meals, and is not conducive to blood sugar control.
There are health risks: the risk of eating a lot of red meat in meat patties, as well as harmful substances produced during frying or frying, trans fat in salad dressing, insufficient nutrient supply and high calories, which have adverse effects on obesity, diabetes, various chronic diseases and even cancer.
Of course, this is not absolute. It is no problem to eat once in a while. It is human nature to be anxious and relieve your craving. As long as you don't eat every day. Do you feel the same way?
