I don't know if you missed that kind of instant coffee in a large glass bottle in your childhood?
But once you taste it, your first reaction is ---- why is this thing worse than medicine?"
Different from today's pursuit of coffee, at that time, people's views on this coffee were extremely complicated, on the one hand, they were deeply influenced by the coffee culture in movies and television, and on the other hand, they could not stand this sour taste.
So in order to cater to everyone's taste, manufacturers have also begun to try a variety of ways.
Feel bitter? So add some sugar to it;
Think the brewing process is too cumbersome? So the direct three-in-one instant coffee appeared, directly in one step;
Think the price is too expensive to buy? So directly from the big assembly to the small bag, with a variety of promotional actions...
Because of this, instant coffee has also begun to enter everyone's life.
Instant coffee, it's really not a good choice
Because of its cheap price, instant coffee often uses uneven coffee beans, coupled with the hard wounds of technology, it is impossible to retain the flavor of coffee beans.
So that's why instant coffee tastes so vulnerable compared to hand-ground coffee.
However, compared to the taste, instant coffee still has a drawback----- sugar is too large!
In order to cater to the tastes of most people, manufacturers will add white sugar, vegetable fat powder, etc., of which the fat powder is what we often call creamer, and some plant fat powder may also have trans fatty acids----- hydrogenated vegetable oils.
What are the effects of large amounts of sugar and trans fatty acids entering the body?
First, gain weight
You know, a bag of about 15g of instant coffee, almost 80% of it is sugar, and the daily added sugar limit for adults is about 50g, you probably drink 2 small bags of instant coffee, almost accounting for more than half of the share.
And because instant coffee has a high sugar content, long-term drinking instant coffee will lead to body gain.
Second, blood glucose levels fluctuate
For diabetics, in the case of drinking coffee, without paying attention to the ingredient list, drinking instant coffee with added sugar will be very easy to cause blood sugar values to fluctuate.
Studies have found that nearly 75% of the ingredients in a cup of instant coffee are added sugars, which are not only bad for diabetics, but also harmful for normal people to drink too much instant coffee.
Third, improve cardiovascular disease
Due to the addition of creamer to instant coffee, creamer is a special additive, the main components of this chemical are hydrogenated vegetable oils, glucose syrup and various preservatives.
Hydrogenated vegetable oil is not a general edible oil, it is a trans fat, and it is very easy to increase the content of carbohydrates in the blood.
The amount of carbohydrates in the blood has increased, which undoubtedly increases the risk of cardiovascular disease.
In fact, in order to cater to the preferences of consumers on the one hand, merchants on the other hand, in order to consider factors such as the shelf life of the product, they often go to great lengths to add different ingredients.
But as long as it is a reasonable addition of regular products, security does not need to worry too much.
What really needs to be worried about is the sugar, saturated fat and possible trans fats in "three-in-one" instant coffee.
For these people, whether it is instant coffee or not, it is not recommended to drink too much:
1. Children and adolescents
Minors under the age of eighteen, the body is in the process of development, the busy pressure of learning is also very large, if you take too much caffeine, it will endanger the quality of sleep and the human brain, for these two groups, it is best not to drink coffee.
2. Pregnant lady
For pregnant mothers, it is not that coffee is not allowed, but it is not recommended to drink too much coffee. Caffeine will stimulate the baby's fetal movement in the stomach, and in the long run, the baby's development in the stomach will be affected.
If you really want to drink, the recommended amount should be reduced by half.
3. People with stomach ulcers
Such groups generally have more gastric juice metabolism, resulting in damage to the gastric mucosa, and excessive coffee drinking will increase the irritation of the gastric mucosa. Therefore, friends with stomach ulcers, even if they want to drink coffee again, need to control the amount.
Of course, today, with the changing market, instant coffee is now also healthy.
For example, instant black coffee, combined with milk, can not only drink silky milk, do not have to worry about sugar and vegetable fat, but also absorb the protein and calcium of milk.
