For normal healthy adults, it is safe and reliable to consume less than 400 mg of caffeine every day. For pregnant women and lactating women, it is recommended to control the supply of caffeine below 200mg.
Generally speaking, the caffeine content of a cup of coffee is about 80- 130mg, and the cup here refers to an 8floz beaker, which is about 240ml. As far as coffee is concerned, a cup of instant coffee a day will not exceed the limit of caffeine standard value.
In fact, coffee is good, which is really beneficial to physical and mental health, refreshing and improving the working ability of fitness. The disadvantage of coffee is that other ingredients in instant coffee will cause bad harm to the body. So if you drink instant coffee again in the future, you should choose pure coffee without sugar and coffee lovers, and add milk seasoning to yourself, which is healthier.
Strictly speaking, instant coffee is not coffee, but a drink! The adverse effects of long-term consumption are:
First, gain weight, because the three-in-one instant coffee contains the ingredients of hydrogenated vegetable fat, which is easy to cause obesity.
The second is carcinogen. Because of instant coffee particles, carcinogens will be formed in the whole process of carbonization in the production and processing.
So, if you really like coffee, try to drink coffee freshly squeezed from coffee beans.
There has been controversy about the advantages and disadvantages of coffee. For coffee lovers, eating one or three cups a day is very enjoyable. Instant coffee provides convenience for consumers, but instant coffee is usually made of inferior raw materials, and in addition to alcohol black coffee without preservatives, many instant coffees also add sugar and lover to improve the taste, which can not be digested, absorbed and metabolized by human body! So if you only drink instant coffee, choose a relatively expensive pure coffee without preservatives!
Non-dairy creamer has been widely criticized. Thus, if it is harmful, it is that non-dairy creamer and sugar are likely to be harmful.
If you only eat instant coffee without extra fat and sugar, laugh at high-end customers who don't know that the real taste will be great, but it won't be harmful to your health.
Instant coffee three-in-one contains non-dairy creamer, and another ingredient is hydrogenated vegetable oil, which is very likely to cause cardiovascular disease in hair. There is also pure coffee. I heard that some research shows that black coffee has anti-cancer effect, but you should not drink too much a day. Coffee is also very easy to cause calcium outflow. If you like to drink coffee, you should pay attention to calcium supplementation.
In fact, frankly speaking, we can't ignore some negative problems of instant coffee on physical and mental health, and at the same time, we can't be too anxious about the harm it provides to physical and mental health. For instant coffee, as long as it is eaten properly, the harm of drinking instant coffee for a long time will not be too great.
