Is coffee a health killer? You need to get these nine benefits of coffee!

Coffee is a widely loved drink. It is one of the three major beverage plants in the world, along with tea and cocoa. Many people like to drink one or two cups of coffee on weekdays, which is both delicious and refreshing. According to a survey, more than 80% of adults around the world have the habit of drinking coffee or similar beverages every day.

You may have had this experience - staying up late to keep up with work schedules or reviewing for exams, drinking a cup of coffee to stay awake, and then experiencing palpitations and rapid heartbeats. Therefore, some doctors advise patients not to drink coffee, or even tea and chocolate, to avoid cardiovascular problems, but we often see claims that coffee can protect the heart.

So, does drinking coffee regularly protect your heart, or is it a health killer?

Scientists in South Korea published a study that found that drinking coffee can reduce the risk of blood vessel blockage. Through a survey of 25,000 subjects, the researchers found that people who drink 3-5 cups of coffee a day have a lower risk of cardiovascular disease.

Medical researchers have long tried to answer this question using methods such as angiography, but have come to very different conclusions. Some experiments have shown that coffee can increase blood cholesterol levels and blood pressure, thereby increasing the risk of heart disease, while other researchers claim that coffee has a protective effect on the heart.

This study by Korean scientists used different research indicators. Previous studies have found that calcium deposits will appear in human blood vessels to varying degrees, and the degree of this deposition is closely related to the onset of heart disease. In the survey, the researchers found that many respondents who had no history of heart disease also had this deposition in their blood vessels. Therefore, the researchers focused on investigating the relationship between this calcium deposition and coffee drinking, and ultimately came to this conclusion. However, the researchers also said that they still need to further verify this conclusion.

The caffeine in coffee is believed to have a stimulating effect on the brain, but it has also sparked debate among many people about whether coffee is healthy.

Health experts in different countries have different views on this issue. Nutrition experts in the United States have recommended that the amount of caffeine consumed by each person should not exceed 400 mg per day, while the United Kingdom believes that there is no need to limit the amount of caffeine consumed by people except pregnant women. The caffeine intake of pregnant women should be controlled below 200 mg, that is, no more than two cups of instant coffee per day. There is still no authoritative conclusion on this debate, but for safety reasons, it is better not to drink more than 400 mg of coffee per day. Drinking tea appropriately is actually a good choice.

What is the correct way to drink coffee?

1. It is recommended not to drink instant coffee

In a serving of instant coffee, the actual coffee content is only about one-fourth to one-third of the original ground coffee. After the concentration of caffeine is reduced, the refreshing effect of instant coffee is greatly reduced.

Just like drinking green tea can relieve fatigue, but the green tea drinks on the market have no such effect. Of course, it cannot be denied that some people with more sensitive nerves can be refreshed even after drinking instant coffee. But it is still recommended not to drink it often.

2. Don’t drink too much

For adults, 80-250 mg of coffee per day is considered a low intake, 300-400 mg is a medium intake, and more than 500 mg is a high intake. It is difficult to determine the specific intake, and you can change it according to your tolerance for coffee.

If you have already achieved the effect of refreshing yourself by drinking coffee, there is no need to increase your intake. Too much is as bad as too little. High intake of caffeine can cause anxiety, irritability, insomnia, irritability and impaired fine motor function.

3. Patients with certain diseases should drink with caution

① Pregnant women

The metabolism of caffeine in pregnant women is slow, which can cause caffeine retention. Excessive drinking can cause miscarriage or fetal malformation. Therefore, for the health of the fetus, pregnant women should stop drinking coffee unless it is absolutely necessary.

Because caffeine can combine with free calcium in the human body and be excreted through urine. The reduction of free calcium will inevitably cause the decomposition of bound calcium, thus leading to osteoporosis.

②Children

If your child likes to drink coffee at a young age, you must stop him. Children's liver and kidney functions are not fully developed, and their detoxification ability is not strong. Caffeine is easy to stay in the body and difficult to excrete. It is harmful to the body. Children under 12 years old should especially avoid consuming caffeine.

③Old women

Researchers at the University of California, USA, conducted a survey on 980 elderly women aged 50 to 98. The results showed that elderly women who drank more than two cups of coffee a day without drinking milk for a long time had lower bone density in the hip and spine, regardless of their age or obesity level. The degree of reduction was related to the duration of the habit and the amount of drinking.

④Patients with liver disease

It usually takes 2 hours for caffeine to be completely metabolized in a normal human body, but it takes 4 to 5 hours for patients with liver disease to complete the process. This will increase the burden on the liver and kidneys. People of this type should be especially careful not to drink coffee at night to avoid accidents.

⑤Patients with digestive system diseases

Coffee contains tannic acid, which can stimulate the stomach to secrete too much gastric acid, causing stomach problems or worsening other digestive system diseases. Caffeine can also enter the stomach wall cells and may directly cause increased acid secretion, so patients with peptic ulcers should not take caffeine.

4. Don’t rely too much on coffee

It is undeniable that coffee is a good refreshing drink. But caffeine is toxic and can make people addicted and dependent on it, and the mental enhancement effect of coffee will be sharply reduced.

Once you stop drinking coffee for a day for some reason, you will experience withdrawal reactions such as fatigue and headache, which will make you feel bad and physically and mentally exhausted. From then on, the beneficial effect of caffeine on you will gradually disappear.

9 benefits of drinking coffee

1. Drinking coffee is good for your skin

Coffee accelerates skin metabolism, speeds up the excretion of waste keratin, and lightens dark circles caused by poor circulation. It is also an anti-oxidant. Drinking coffee regularly can keep skin cells full of vitality, prevent cell oxidation, and has a great effect in fighting aging.

2. Drinking coffee can prevent and fight cancer

The polyphenols contained in coffee are a strong antioxidant. Drinking some coffee every day has a certain effect on cancer prevention and treatment.

If you drink more than three cups of caffeinated coffee a day, women with basal cell carcinoma have a 21% lower risk than those who drink less than one cup of coffee a month. At the same time, caffeine can also effectively inhibit the growth of tumors in the body.

If women drink 4-6 cups of coffee a day, the incidence of breast cancer will be reduced by 25%-70%, even for women with a family history of breast cancer. This is because coffee can reduce the production of estrogen, which has a carcinogenic effect.

3. Drinking coffee after meals nourishes the stomach and aids digestion

Drinking coffee after a meal is good for stomach health. But on the contrary, if you drink coffee on an empty stomach, the secreted gastric juice will damage the gastric mucosa, thus damaging stomach health.

People who love meat are best to drink a cup of coffee after a meal, which has a good effect of removing greasiness and aiding digestion. In addition, the content of soluble dietary fiber in coffee is higher than that in orange juice, and caffeine can also stimulate the intestines to speed up peristalsis. Therefore, drinking coffee has the effect of relieving constipation.

4. Drinking coffee protects your liver

In recent years, many studies have shown that drinking coffee can greatly reduce the risk of cirrhosis and liver cancer, and the polyphenols contained in coffee can also protect our liver. Therefore, we recommend that hepatitis patients drink some coffee every day, which can repair liver cells well.

Drinking coffee may help reduce the risk of liver disease in people who drink alcohol, are overweight, have diabetes or iron overload, but there is no evidence that coffee and tea reduce the risk of chronic liver disease due to fatty liver disease or viral hepatitis.

5. Drinking coffee can prevent radiation damage

Radiation damage has become a prominent pollution and hazard at present. Especially the radiation from household appliances: such as people who use computers for a long time, microwave ovens, TV sets at home, etc. Especially the radiation to pregnant women (pregnant women's food), has affected the health of the next generation (healthy food). Some studies have indeed shown that coffee may help prevent radiation damage.

6. Drinking coffee can relieve sports soreness

Drinking two cups of coffee after exercise can help relieve muscle soreness. A research report pointed out that drinking coffee can help people relieve muscle pain caused by excessive exercise. Although caffeine can relieve exercise pain, it is often only effective for people who do not drink coffee often.

7. Drinking coffee can help you sober up

Chlorogenic acid in coffee can prevent alcohol poisoning. Drinking coffee after drinking alcohol will cause the acetaldehyde converted from alcohol to be rapidly oxidized, decomposed into water and carbon dioxide and excreted from the body.

8. Drinking coffee can prevent gallstones

Some studies suggest that caffeinated coffee can stimulate gallbladder contraction and reduce the cholesterol in bile that is prone to form gallstones. Drinking coffee can reduce the risk of people suffering from the most common and painful gallstone disease.

9. Drinking coffee can prevent depression

People who drink coffee regularly will feel happier, less irritable, and better in mood. When you are irritable or depressed, drinking a cup of coffee can really calm your mood.
