The lunch box for office workers must first meet the nutritional supply. Generally speaking, green beans, tofu, carrots, etc. can be added to vegetarian dishes. Considering the problem of preservation, melon vegetables should be the main ones, and leafy vegetables should be supplemented.
In addition, protein foods should be sufficient, and staple foods should be based on individual needs. If office workers have the habit of eating snacks in the office, they should choose fruit, milk, yogurt, and corn, but they should not completely replace lunch with these foods for a long time.
Eating more fruits can make up for the vitamins lost in the storage process of vegetables. It is recommended to eat before 10 am and after 2:30 pm, so it will not affect the lunch. It is not advisable to eat too many highly processed foods, such as preserved fruits that are high in oil and salt.
Another issue with packed lunches is food safety. The lunch box food must be placed in the refrigerator. If there is no refrigerator in the office, it is best to give up this method, because the bacteria of the food multiply rapidly under high temperature, and it is easy to cause acute gastroenteritis after eating it. If there is no refrigerator, it is recommended to use a special lunch box that can keep warm for a long time. Cook the meals as much as possible without adding too much juice, as gravy vegetable juice is a medium for bacteria to grow.
When vegetables are cooked for a long time, it is easy to produce sodium nitrite, a strong carcinogen. In order to ensure vitamin supplementation, you can bring fresh cucumbers and tomatoes, slice them when eating, and eat them raw with lunch. If the hygienic quality of vegetables is guaranteed, you can make your own salad. Because it needs to be heated in a microwave oven, the lunch box must be a qualified product that can be heated by microwave. The choice of plastic material is very important. It is necessary to choose food-grade plastic that meets health standards to prevent toxins from seeping into the food.
