Coffee is one of the most popular drinks at the moment, and many people drink a cup of coffee at work, leisure and entertainment, which is refreshing. And a large number of studies have proved that proper consumption of coffee is very good for human health, but the coffee refers to freshly ground pure coffee, not the common instant coffee in our life.

What is the harm of drinking instant coffee often?

First of all, the raw materials for the production of instant coffee are mainly "low-end" Robusta beans (because of their bitter taste and high caffeine content), and only diseased, broken and malformed eliminated beans are used to produce instant coffee. Of course, in recent years, there have been some "boutique instant", but the overall situation has not changed, is still the use of the best coffee beans to produce instant coffee.

Secondly, the roasting degree of instant coffee beans is often not enough, stay in a relatively primary stage, can not give full play to the aroma.

Finally, most of the aroma substances in coffee disappear when extracted with high temperature steam, and most manufacturers add flavors to make up for the lost aroma in the process of extraction, concentration or drying.

Therefore, instant coffee is about equal to artificially extracted bitter spices, and the nutrition of natural coffee beans is basically destroyed, and there is no natural aroma and mellow taste.

Instant coffee does great harm to the body, so can coffee partners drink it alone?

Instant coffee itself is almost "junk food", but even more rubbish is the so-called "coffee companion". It includes a variety of "three-in-one" instant coffee, which is a mixture of sugar and coffee companions in instant coffee.

Let's take a look at a list of common brand coffee companions and 2: 1 instant coffee ingredients:

Coffee companion, that is, the so-called "cream", the main ingredients are hydrogenated vegetable oil, glucose syrup, casein, spices, food pigments, etc., the role is to increase the flavor of milk in food, instead of pure dairy products to reduce costs.

Hydrogenated vegetable oil is intended to reduce the unsaturation of vegetable oil so that it can remain solid and conducive to production and processing, but because of the need for high temperature and high pressure in production, as a result, a large part of non-hydrogenated vegetable oil has changed from natural cis structure to trans structure and into trans fatty acids.

The hazards of trans fatty acids include: the inhibitory effect of ① on growth and development, which is easy to make fetuses and children suffer from essential fatty acid deficiency. ② induces cardiovascular disease, which increases the content of low density lipoprotein in the blood and reduces the content of high density lipoprotein. ③ is easy to cause fat accumulation, leading to obesity. ④ induces the expression of proto-oncogenes and leads to cancer.

Among them, especially the cardiovascular harm is very great, people who eat trans fatty acids are more likely to suffer from heart disease such as coronary heart disease or obesity than the general population.

In short, coffee lovers, for the sake of your health, must abandon all kinds of cheap instant coffee on the market, be sure to drink, just drink some good ones.
