A cup of coffee a day is good for your health

Many white-collar workers have a cup of coffee every morning and then go to work energetically. In Europe and the United States, three or two cups of coffee a day is also a part of life . So, what is the charm of coffee that makes the world fall in love with it? The answer lies in the unique aroma and taste of coffee itself, which gives people a sensory enjoyment . Another important feature is the caffeine contained in coffee. In addition to stimulating the nervous system to keep us awake, it is more beneficial to our health.

①One of the anti-oxidation magic weapons

"Caffeine contains a lot of antioxidants that fight free radical damage." Although this sentence sounds a bit profound, the mechanism is actually very simple. Free radicals are like a crazy race that attacks cells, proteins and DNA, eventually leading to skin aging. But our body uses antioxidants to resist them, and caffeine is one of the sources of such antioxidants. According to a recent study of white American women, drinking 3-4 cups of coffee a day can reduce the risk of skin cancer by 30%.

②Temporarily eliminate edema

The effect of constricting blood vessels is also a major feature of caffeine. Of course, the biggest effect is to reduce dark circles and swelling. This is because the caffeic acid in it has a metabolic function, which can help break down old lung substances in the body, making it easier for the body to metabolize them. Caffeine can also promote blood circulation in skin tissue and help break down local fat . Of course, caffeine can only temporarily dehydrate mast cells, drain the water in mast cells, and make the contours tighter and more stylish in a short period of time (usually lasting 2-3 hours).

③Keep distance from radiation

According to research by American scientists, caffeine can protect the skin from UV damage . If caffeine detects that DNA is damaged during the division cycle, it will terminate the cycle and allow DNA to be repaired, while healthy cells will not be damaged at all. Therefore, caffeine can prevent radiation from the sun and computers. Drinking black coffee in moderation can protect against the sun and can also resist oxidation and inhibit and neutralize free radicals.

④Quick skin awakening assistant

Caffeine also has a powerful ability to wake up the skin. It can stimulate skin cells and promote blood circulation to achieve the effect of refreshing the mind. It can quickly activate the skin itself, make it cooler and more comfortable, and instantly lift people's spirits and eliminate fatigue .

⑤Prevent cognitive impairment

There have been many studies on the effects of caffeine on short-term memory in the past, but recent studies have shown that it has a positive effect on long-term memory. "About 300-400 mg of caffeine per day can prevent cognitive decline and Alzheimer's disease ," Jaclyn London, senior dietitian at Mount Sinai Hospital in New York, told us. "One thing to note is that adequate sleep is also important for preventing Alzheimer's disease, so if you are allergic to caffeine, you can make up for it by getting enough sleep. And caffeine can easily cross the blood-brain barrier, so the central nervous system is easily stimulated." This means that after drinking coffee, you will quickly feel that you are in a state of sharp thinking and alertness , especially reaching a peak after 30-60 minutes.


LINK: Don’t worry about side effects

It has to be mentioned that a large number of people are worried about the side effects of caffeine. They seem to think of addiction and dependence first when they mention caffeine. In fact, it is nonsense to talk about side effects without mentioning the dosage . Caffeine is one of the substances produced by the human body. Its safety to humans is beyond doubt. Only when caffeine is taken in large quantities and for a long time, dependence or addiction may occur. Therefore, we recommend that the daily coffee consumption (based on a cup of American coffee 300ml) is between 1-4 cups, which is good for your body and mind.


LINK: Q&A about caffeine

Q: Will drinking coffee for a long time change the color of my lips?

A: No, coffee will only discolor your teeth and will not affect the skin color of your lips.

Q: If I don’t want to damage my skin, is there a safe daily dose of coffee?

A: There is no uniform standard, it depends entirely on individual circumstances. One cup of coffee a day has been proven to be good for health .

Q: What are some ways to prevent the negative effects of caffeine on the skin?

A: The negative effect of caffeine is dehydration, which is not good for the skin or body. About 98% of caffeine is taken in through beverages, which means that you replenish water while taking caffeine. So although caffeine is a diuretic, it will not really dehydrate you. However, this does not mean that you can choose coffee drinks recklessly. You still have to stop when you have enough. Don't forget that only plain water can really replenish water. ( Of course, it is also recommended to drink more plain water after drinking coffee, and never use coffee instead of water )

Q: Is drinking coffee a way to lose weight?

A: The caffeine in coffee will generally increase the concentration of fatty acids in the blood 30-40 minutes after drinking. Once the concentration of fatty acids in the blood increases, the fatty acids will be absorbed by the muscles and consumed in a way that converts body energy. In other words, drinking a cup of coffee every day can promote the decomposition of fat that has been accumulated in the body for a long time.
