Light food sought after "grazing" will be able to thin?

Expert: Eating some uncooked vegetables in salads directly or at some risk

In Guangzhou, the main light food restaurants bloom everywhere. Reporters visited and found that in Sports West Road, sports center, there are more than 10 restaurants that specialize in light food. There are also some fruit shops that have been transformed into main-salt restaurants, and some restaurants have added many improvements to the menu. Light food products, some bakeries, tea shops began selling salads. However, experts believe that if salad is always used as a staple food, it will cause nutritional imbalance.

With the rise of national fitness, light food has also become popular. Not only did the number of light food restaurants rise sharply, but many restaurants also began to transition to light food. Famous brands such as KFC, Sha County, and Yoshinoya also joined the battle.

The concept of “light food” was originally started from the category of salad, but the variety it contains is far more than that. It refers to low-sugar, low-oil, low-salt, high-fiber foods, including hamburgers, sandwiches, and fruit and vegetable beverages that have been transformed with coarse grains. This type of dish, with a small amount of ingredients, is light in taste, and uses steamed, boiled, stewed methods to retain more original flavor.

Salad is still the main light food. On the take-away platform, the more popular light-salt salad restaurants in Guangzhou have sold more than one thousand per month, and more than 4,000 single-serve restaurants. According to the data provided by a food delivery platform, white-collar workers and college students are the most interested in ordering salads. White-collar workers account for the largest proportion of orders, and the amount of orders exceeds 60% of the total orders. The regions with the most orders for salads are mainly distributed in Guangdong Baiyun College, Sun Yat-sen University Southern College, Tianhe City, Jiangxia, Kecun, Jiangnanxi, and Sports West. The most popular salads in Guangzhou are fruit salad, vegetable salad, tuna salad, cucumber salad, yogurt salad, salmon salad, tuna salad, German chicken salad, potato salad, and chicken breast salad.

Ms. Zhang, who lives in Huajing East Road, recently started to call her a salad delivery. After her work, her weight went straight up. She hopes to lose weight by improving her eating habits. She showed reporters the salad she had recently eaten. It contained lettuce, tomatoes, broccoli, corn, sweet potatoes, and boiled chicken breast. Like Ms. Zhang, many people use salad as a staple food, hoping to reduce caloric intake and lose weight.

Experts: "grazing" but also pay attention to nutritional balance

The colorful salads on the salads appear to be healthier than the greasy meats. But in fact, it's not. Some uncooked vegetables added to the salad are eaten directly or at some risk. Zhao Yongyi, director of clinical nutrition at the First Affiliated Hospital of Guangdong Medical University, told reporters that if improperly handled, raw vegetables may have bacterial contamination and microbial contamination, and some vegetables contain pesticides that cannot be washed away by pure cleaning.

Many people want to reduce calorie intake through more "grazing", but the reporter learned that "grazing" is not necessarily less calories because of "salad dressing." The salad dressings currently on the market are mainly mayonnaise, thousand island sauces, and salad dressings in general. 100g of heat is about 700 kcal, and the heat is twice that of French fries.

"If it is a good salad dressing, there is still a certain nutritional value. But if you use a salad dressing made with some lard, artificial butter, etc., it will contain a lot of trans-fatty acids. Trans-fatty acids are harmful to the human body. Clinical experience shows that trans fatty acids are more harmful than saturated fatty acids, and many cardiovascular diseases such as arteriosclerosis are associated with them.” Zhao Yongyi told reporters.

Even if they do not add salad dressings or choose low-calorie salad dressings, Zhao Yongyi does not recommend that the neighbours use light meals such as salads as a staple food to lose weight. “If you always use salad as a staple food, it will cause imbalance in nutrition. The staple food should be carbohydrates, that is, starchy things. If you want to lose weight, you can eat more coarse grains and eat less refined food. Secondly, the balance should be balanced. The people have a misunderstanding, I think you can lose weight by eating less, but eating less will also lead to a lower energy metabolism rate. When you eat a little more, the possibility of rebound is very high, so we must increase the energy metabolism rate and increase the metabolic rate. The only way to lose weight is to consume more than you consume, and to combine exercise and diet."
