What food must I bring for a field trip? 1, be sure to drink more water in the morning, because people will lose a lot of water at night, and at the same time eat some starchy foods rich in sugar, such as steamed bread. If you have no conditions, you can eat sugar and chocolate, and then eat something with slow digestion, such as very dry bread and dried meat. These things will make you not hungry all day. There are two ways to eat at noon. First of all, when there is enough time and conditions, you can cook some boiled meat slices (with dishes and condiments). Remember to drink soup, this is the essence. If you don't have meat dishes, boil water to make a mixture of yellow bean, millet flour, corn flour and sesame flour. Second, you don't have enough time and conditions. For example, there is no lunch on the way to mountain climbing. As long as you don't pass through the dangerous area, you have to keep walking. No matter this meal, you should pay attention to efficiency. Don't choose food that is too difficult to digest when hiking. You should know that you are tired after walking for half a day in the morning. Eating indigestible food will increase the burden on the stomach, increase the blood supply to the stomach and even reduce the blood supply to the brain (which is why we often feel tired after lunch). Action food for hiking is prepared in the morning or even the night before, usually carbohydrates, compressed dry food, pickles and tea; You can treat yourself with something delicious in the evening, depending on the food you bring. I like to mix pork liver with pepper and salt (delicious), cook a box of chicken soup with a bag of chicken essence and add two rice balls. Take Xiancun after meals and sometimes add a few amino acid capsules. Eat some candy before going to bed. 4. Prepare more small pieces of chocolate, which is an excellent source of heat, and potatoes, which are a ubiquitous food. I ate it every day when I was in Tibet, and I bought it from my hometown. When cooking with fire, throw it under the fire and bury it with burnt firewood. When cooking, the fragrance floats on it, which makes people drool. There are many ferns and wild mushrooms in the forest, which are delicious (just pay attention when picking mushrooms, bright colors may be poisonous). Remember to cook the mushroom soup once, add ham and sausage, and then make instant noodles with pepper. That was good. 6. Canned food is a good wild food. I usually buy a small package, eat a little at noon, seal it with plastic bags, and solve it completely at night. After eating, I will pour the remaining oil into the water to make soup. 7. Bring some milk powder so that you can have milk to drink. 8. When preparing wild food, it must be targeted, and each food must be chosen for a reason, whether it is rich in protein or contains a lot of trace elements, and whether it is convenient to carry or cook. You know, the size of the backpack is so precious.
