Many working groups like to drink coffee to refresh themselves. Generally, you may drink instant coffee, because instant coffee is more convenient and meets the tastes of ordinary people, and ordinary coffee is inconvenient. But some people say that drinking coffee for a long time will make you fat, which is harmful to people's health. Let's look at their differences and harms.

It will increase the risk of cancer, and acrylamide, a carcinogen, is more likely to be produced during the production of instant coffee. Acrylamide is not an additive, but a substance produced by a series of polymerization reactions in the process of high-temperature cooking.

The production process of instant coffee involves a series of processes such as pretreatment, baking, grinding, extraction, concentration and drying. In this production process, the risk of high-temperature production is everywhere, and there are more than one process of high-temperature production, which increases the risk of acrylamide. When the heating temperature exceeds 120 degrees Celsius, acrylamide will be generated.

Although freshly ground coffee has to go through the roasting process, there are relatively few steps in the production process, so the acrylamide content can be reduced accordingly. In addition, due to fewer steps, the loss of saturated fatty acids, potassium, magnesium, vitamins and other beneficial components in freshly ground coffee is less, so the overall taste is better than that of instant coffee.

Instant coffee and freshly ground coffee are different in making process, taste and harmful factors. But these differences are not great. Even the harmful substance acrylamide, as long as its content is strictly controlled, its risk can be ignored. As for the subtle differences in taste, for many people, it is impossible to feel directly. Moreover, although there are not many procedures for grinding coffee now, because coffee beans need special tools and equipment to be ground into powder, and coffee beans are hard, if you don't know how to do it, you can't drink coffee at all.

Ordinary coffee is inconvenient to make. In terms of coffee promotion, freshly ground coffee has no promotion advantage because it is relatively troublesome to make. Instant coffee can be made in advance through the running water production mode before industrialization, and then it can be brewed.

Coffee has always been a refreshing drink for us, but there are many harmful substances in coffee that are harmful to people's health. Drinking less and not drinking too much will also be harmful to some patients with cardiovascular diseases.
