The advantages and disadvantages of instant coffee

If you drink or eat a food too much, the benefits will become the possibility of health hazards. Then before eating fruit and food, we should first understand some of their characteristics and properties, so that we can eat it better, and do not worry about the advantages turning into disadvantages. So what are the advantages and disadvantages of instant coffee?


1. Coffee contains certain nutrients. The nicotine of coffee contains vitamin B, and the content of roasted coffee beans is higher. And there are free fatty acids, caffeine, tannic acid and so on.

Coffee is good for skin. Coffee can promote metabolic function, activate digestive organs, and has great effect on constipation. Taking a bath with coffee powder is a kind of thermotherapy, which can reduce weight.

3. Coffee has the function of relieving alcohol. Drinking coffee after drinking will make the acetaldehyde converted from alcohol quickly oxidized, decomposed into water and carbon dioxide and discharged from the body.

Coffee can eliminate fatigue. To eliminate fatigue, it is necessary to supplement nutrition, rest and sleep, and promote metabolic functions, and coffee has these functions.

5. Three cups of coffee a day can prevent gallstones. Caffeine can stimulate the contraction of the gallbladder and reduce the cholesterol in the bile that is easy to form gallstones. Researchers at Harvard University have found that men who drink two or three cups of coffee a day are less than 40% likely to develop gallstones.


1. Make trouble when you are nervous

Caffeine improves alertness, sensitivity, memory and concentration. But drinking more coffee than you are used to drinking will produce a similar dose of stimulants, which can cause nervousness. For people prone to anxiety disorders, caffeine can worsen symptoms such as palmar sweating, palpitations, and tinnitus.

2. Aggravating hypertension

Because of its analgesic effect, caffeine is often compounded with other simple painkillers. However, if you take a large amount of caffeine for a long time, if you already have high blood pressure, using a large amount of caffeine will only make your situation worse. Because caffeine alone can make blood pressure rise, if coupled with emotional stress, it will produce a dangerous multiplier effect. Therefore, people at risk of hypertension should especially avoid drinking caffeinated drinks when they are under great pressure at work. Some people who drink coffee all the year round think they are immune to the effects of caffeine, but this is not the case. A study has shown that after drinking a cup of coffee, blood pressure can rise for up to 12 hours.

3. Induce osteoporosis

Caffeine itself has a very good diuretic effect. If you drink a lot of coffee for a long time, it is easy to cause bone loss and has adverse effects on the preservation of bone mass. For women, it may increase the threat of osteoporosis. But the premise is that people who don’t take enough calcium in their daily food, or people who don’t often move, and women after menopause lose calcium due to lack of estrogen. These conditions, together with a large amount of caffeine, may pose a threat to bone. If you can enjoy it in a reasonable amount, you can still stop eating because of choking.
