Normal consumption of self-heated rice in moderation has no effect on the body, but excessive long-term consumption is not recommended. If there is a breakage of the heating package, consumption may cause some harm to the body. Self-heating rice is heated by using chemical substances to react with water. Although the rice is separated from each other by the chemical substances, it may be contaminated by the chemical substances in the heating pack, and consumption at this time may be harmful to the body, and food poisoning such as abdominal pain, diarrhea, nausea and vomiting may occur. The nutrients in self-heated rice are not balanced enough, and long-term consumption may lead to malnutrition. Self-heating rice is also not freshly made, so it is likely to lead to nutritional loss and therefore is not recommended for long-term consumption. It is recommended to enrich the diet, and people who are in a position to do so can cook their own rice, with appropriate meat, vegetables and fruits, and pay attention to a balanced diet. In addition, self-heated rice usually adds a certain amount of food additives in order to increase the storage time, which can have certain effects on the body if consumed in large quantities for a long time, so long-term consumption should be avoided as much as possible, but once in a while it is harmless. In addition, the texture of self-heated rice is hard, so too much consumption may cause indigestion. When consuming it, you should pay attention to make the rice fully heated to avoid gastrointestinal discomfort.
