Can a compressed biscuit really last a day?

As we all know, soldiers carry enough guns and ammunition when marching, and it is also important to carry food. Soldiers are nervous for a long time, and fighting with the enemy consumes a lot of physical strength. If they don't replenish their strength in time, it will be difficult for everyone to concentrate on dealing with the enemy. However, due to the limited battlefield conditions, the general food is not enough to fill the stomach, and there is no place to make a fire to cook, so the food they bring must meet the advantages of convenience and fullness. At this time, military compressed biscuits were sent to the battlefield.

Does this petite biscuit with simple packaging really have such magical effect? This kind of biscuit is made of indigestible foods such as wheat, coarse grains and dairy products, and even contains dried fruits and floss. Therefore, it has high energy and has a miraculous effect on filling the stomach.

Military compressed biscuits are easier to carry and fill the stomach by reducing the volume and increasing the density. But ordinary soldiers don't like it. Why?

A military biscuit can't be digested by the stomach quickly after it enters the body, so it will bring a feeling of fullness. So this kind of biscuit can't be eaten often, and it's easy to get indigestion if you eat too much. But also brings a sense of fullness, and the body does not absorb nutrients. Long-term consumption can also cause malnutrition. Moreover, this kind of biscuit tastes bad, hard and dry, so even soldiers don't like it. If there are self-heating rations, no one will choose compressed biscuits, so compressed biscuits have become the last choice of many soldiers.

An army fan once did an experiment on the digestion resistance of compressed biscuits. He put a compressed biscuit into a pot of boiling water, and the biscuit would not be dispersed in water like ordinary biscuits. After cooking for 30 minutes, the biscuit still doesn't melt, so its anti-digestion ability is not just talk.
