1. What are the hazards of instant coffee
1. Cardiovascular and cerebrovascular diseases are damaged
The high incidence of cardiovascular and cerebrovascular diseases in modern people is closely related to the fact that people like to drink instant coffee in daily life. Some experts pointed out that the main ingredient in instant coffee is non-dairy creamer, and its composition is very complicated, including glucose syrup, hydrogenated vegetable oil and various food additives. However, none of these additives is beneficial to human health. Even some big brands of coffee also have various additives, which will seriously affect human health if they are drunk for a long time.
Moreover, these instant coffees also contain a lot of hydrogenated vegetable oil, and there are also a lot of "trans fatty acids" in this ingredient. If you drink this kind of coffee excessively, it will lead to excessive intake of trans fatty acids, which will seriously affect cardiovascular and cerebrovascular health.
2. Poor quality
It can be said that no matter how big the brand of instant coffee is, its quality is very poor. Many times, due to the cost problem, most coffee manufacturers will choose Robusta's coffee. The coffee is mostly produced in Vietnam, China, Hainan, Yunnan, Africa and other countries. In the raw materials of these instant coffee, there are also a lot of broken beans, bad beans and unhealthy varieties, which are often baked and ground directly without screening in the production process.
It can be said that this kind of coffee often only extracts caffeine, so there is a lack of aroma. However, at this time, in order to make up for this shortcoming, many merchants will use a lot of flavors and additives to blend, which leads to the worse quality of instant coffee.
3. Carcinogenesis
Some foreign studies have found that drinking pure coffee properly has the function of preventing cancer, but for some instant coffee, it is just the opposite. The latest research found that if you often drink too much instant coffee in your daily life, it will not only be very harmful to human health, but even cause cancer. Acrylamide is a carcinogen, and all kinds of instant coffee contain acrylamide, which will cause cancer if you drink it for a long time.
Among the more than 1 samples monitored, the foods with high acrylamide content are potato fried food, cereal fried food, cereal baked food and instant coffee, etc. Therefore, we should try to avoid eating such foods for human health.
4. Insomnia
It can be said that in all kinds of instant coffee, besides a large number of additives, the largest content is caffeine, which is also very harmful to human health. Caffeine has the effect of invigorating the central nervous system, so never drink coffee before going to bed at night, so as not to affect your normal sleep. It is best to drink it 3-4 hours before going to bed at night, so as to ensure that sleep will not be affected.
These are the hazards of instant coffee, so experts remind some coffee lovers that it is best to buy their own coffee beans and grind them for drinking, so that they can not only taste the unique natural aroma of coffee, but also not affect human health.
2. What should you pay attention to when drinking coffee?
1. Diabetic patients suggest drinking decaffeinated coffee instead.
2. People who have symptoms of hyperlipidemia should drink follicular coffee.
3. Patients with hypertension should pay attention to the time of drinking coffee, and try not to drink coffee after getting up in the morning to avoid blood pressure rising too high at once.
4. It's best to drink coffee after breakfast, because drinking on an empty stomach may cause irritation to the stomach and be harmful to health.
5. Considering the cost, a cup of coffee from 5 yuan and 1 yuan usually does not use better quality coffee beans. As for three-in-one coffee, most of them are made of coffee essence or coffee seasoning powder, and it is impossible to make good use of coffee beans, and the sugar and creamer added inside are high in calories, so drink less.
6. Smell it before you taste it with your tongue. When drinking coffee, don't swallow it, but smell it close to your nose first. If it smells spicy, it means the coffee beans are not fresh. After passing the smell test, take a sip of coffee in your mouth, taste it gently with your tongue and slowly swallow it down your throat. If it tastes clean and bright, the aroma is full and pleasant, and the body has no adverse reactions, it is a good cup of coffee.
7. It is suggested to replace creamer with fresh milk and add less sugar to avoid offsetting the original benefits of coffee.
8. A small amount of coffee has nothing to do with pregnancy, abortion, birth defects, premature delivery and low birth rate. However, for those women who are pregnant or planning to be pregnant, it is best not to consume more than 2 milligrams of caffeine every day, because a large amount of caffeine will lead to miscarriage.
It is safe for children aged 9, 6 to 9 to consume 22 milligrams of coffee every day. However, many children are very sensitive to coffee and will have temporary anxiety or irritability. Moreover, most of the caffeine consumed by children comes from carbonated drinks, energy drinks or tea with sugar. These drinks are rich in sugar, which will lead to obesity in children. Therefore, even if caffeine is harmless, coffee drinks are not good for children.
3. Tips for choosing coffee
1. First, try not to choose instant coffee but freshly ground coffee. Although instant coffee is convenient, if you look carefully at the ingredient list of instant coffee, it will contain some non-dairy creamer, which contains trans fatty acids, which is not good for human health.
2. Look at the nutrient composition table of instant coffee again. It is high in fat and carbohydrate, and unconsciously consumes too much energy. Some women who love beauty may control their energy intake by strictly controlling their diet, but they don't know that a cup of instant coffee may make up for the controlled energy.
3. When drinking freshly ground coffee, milk should be used instead of creamer, and a small amount of sugar should be added. Emulsifier is actually non-dairy creamer. Replacing creamer with milk not only improves the nutritional value, but also tastes good.
