하루 카페인 권장량
Today we will take a look at the recommended amount of caffeine per day. The reason why you need to know the recommended amount of caffeine per day is because coffee is one of the most consumed beverages by adults in Korea.
Caffeine is a plant alkaloid component found in a variety of plants, including cacao, coffee, and tea. Did you know that caffeine is the first ingredient to separate this substance from coffee beans? Caffeine is said to help plants protect themselves from animals and to protect their territory by interfering with the growth of nearby plants. Aren’t you curious?
Effects of Caffeine
When caffeine enters our body, it stimulates the adrenal gland to promote the secretion of adrenaline and noradrenaline, and as a result, it affects and awakens many bodily functions such as the brain, heart, kidney, and stomach. Due to this action, caffeine is used in various medicines, energy drinks, as well as drinks and snacks that children like, such as cola and chocolate.
Caffeine Benefits
That’s not to say that caffeine has any negative effects. But while there are a few people who are negative about it, I’ve read many articles about coffee and energy drinks about their dangers, but caffeine isn’t all bad. It is also used in many medicines such as cold medicine and painkillers.
Anything is good if used properly, and if you exceed the limit, it will have a bad effect, and the same goes for caffeine.
awakening effect
Caffeine is a natural stimulant that is not harmful. Its main effect is on the central nervous system, where caffeine, which you know all too well, wakes you up when you’re tired and gives you a much-needed boost. This effect peaks within one hour of caffeine consumption and halves within about four to six hours. However, people’s reactions to caffeine differ depending on their sensitivity to it and how quickly they digest it.
This awakening effect is the most representative reason for taking caffeine and the expected effect. When the body enters a state of awakening, the efficiency of all work, study, and exercise increases. Have you ever felt that drinking coffee helps you fall asleep and clears your mind? This is what happens when caffeine acts on the central nervous system.
Caffeine interferes with the activity of an inhibitory neurotransmitter called ‘adenosine’ in the brain and also affects the secretion of hormones such as dopamine and adrenaline. This adenosine is deeply involved in sleep, and caffeine interferes with it, making it difficult to fall asleep.
lipolysis
As mentioned above, this kind of caffeine affects the activation of the human body and also affects the secretion of hormones. Through this, the concentration of adrenaline in the blood increases, and since this directly acts on the fat cells through the blood, it promotes the breakdown of fat, which is a helpful principle for dieting.
Consuming caffeine also increases your basal metabolic rate. Simply put, the energy used naturally increases. It is natural that as much as the human body is active, energy consumption increases. It is also said that it can help with diet. Also, for reference, it is more meaningful that this increase in metabolic rate is caused by fat burning, as I just said above.
Recommended amount of caffeine per day
For adults, less than 400mg, pregnant women less than 300mg, children and adolescents less than 2.5mg per 1kg body weight. This information was reported by the Ministry of Food and Drug Safety on March 18, 2020. The average of domestic franchise coffee is 136mg, and the average of convenience store coffee is 93mg.
Caffeine Side Effects
1. Addiction
Caffeine has many benefits as mentioned, but if consumed continuously, it can lead to habituation and eventually addiction. It does not lead to a serious form, but psychologically, you naturally crave more, and if you do not meet this, you may experience headaches, fatigue, and various forms of withdrawal.
2. Immunity
Continuing intake eventually develops a tolerance in the body and prevents you from enjoying the effects of caffeine properly.
3. Lack of water due to diuretic effect
Don’t you go to the bathroom often when you drink coffee? In fact, regular coffee is not a big problem because it is consumed with sufficient moisture, but if you take it in the form of a booster, you must provide enough moisture to prevent the symptoms of dehydration.
Today, I learned about the benefits and side effects of caffeine, and the recommended amount of caffeine per day. Now, it is one of the most precious drinks that cannot be separated from everyday life, but I hope you enjoy a safe and healthy coffee life by referring to today’s article. thank you!
