Coffee and tea cocoa are called the three biggest drinks in the world. The strong aroma of coffee has attracted many enthusiasts, especially among young people. Some people even have one or more cups a day. In short, they are not happy without coffee; others do not drink coffee and do not touch it, which varies from person to person.

Let's have a mixed cup of coffee. What do you know about it?

Does coffee prevent cancer or cause cancer?

Once a cancer patient asked: does coffee have a cancer-preventing effect? What is the effect of drinking more on your health? In particular, we can see that cancer shows a younger trend in clinic, many people have the habit of drinking coffee, and the rate of drinking coffee in urban population is not low, so the effect of coffee on cancer is discussed here.

At present, the anti-cancer effect of coffee has been supported by many studies. Athens scholars have revealed that the mystery of the longevity of the residents of the Greek island of Ikaria is related to their love of coffee, and the incidence of cancer and heart disease is 20% lower and 50% lower than the average in other western countries. The researchers believe that taking 25 to 50 milliliters of black coffee a day is ideal, but drinking more is not good for health.

Harvard Medical School also believes that coffee has the effect of preventing skin cancer. Studies have found that drinking coffee is an important measure to prevent basal cell cancer, and coffee consumption is inversely proportional to the risk of skin cancer. Men and women who drank more than three cups of coffee a day had a 9% and 20% lower risk of basal cell cancer, respectively, compared with those who drank less than one cup of coffee a month. However, drinking coffee does not reduce the risk of the other two types of skin cancer (squamous cell carcinoma and melanoma).

The anti-cancer effect of coffee on women can not be ignored. Roswell, USA? A study by the Park Cancer Institute found that women who drink tea or coffee regularly can reduce the risk of endometrial cancer. The institute followed 1100 women and found that women who regularly drank tea or coffee were less likely to have endometrial cancer than those who did not, and the more they drank, the lower their risk of developing the cancer. People who drank more than 4 cups of tea or coffee a day (one cup is about 250 milliliters) had a 50% lower risk of endometrial cancer than non-drinkers; those who drank 2 cups of tea or coffee a day had a 44% and 29% lower risk of developing this cancer than non-drinkers. Although coffee has anti-cancer effects, some scientists say that drinking a lot of coffee can cause other health problems, so there should not be a significant increase in coffee intake based on such research results.

Some scholars have put forward opposite views on the anti-cancer effect of coffee. The National Cancer Center of Japan released the results of its study of 100000 Japanese who drank one cup of coffee a day, especially non-smoking men, who had an increased risk of bladder cancer. The researchers divided the subjects into three groups according to their caffeine intake, and the analysis showed that people with high caffeine intake had a twice higher incidence of bladder cancer than those with low caffeine intake.

For the anti-cancer effect of coffee, there is not a consistent conclusion, coffee in addition to the possible anti-cancer effect, other health effects can not be ignored.

Studies conducted by American biologists have shown that drinking two to three cups of coffee a day has a positive effect on protecting the heart. If there is a problem of being overweight, coffee can increase metabolism, reduce appetite and play a role in losing weight.

Another advantage of coffee is that it can enhance physical strength, enhance attention and reaction ability, and make the exercise effect better.

Moderate drinking is the key to benefit.

Coffee has both advantages and disadvantages to the human body, moderate consumption of coffee is the key to benefit from it, so it is very important to grasp the degree.

Let's see what we should pay attention to when drinking coffee:

1. Long-term or large amounts of coffee drinking in patients with high blood pressure and coronary heart disease will increase the content of cholesterol in the body and cause cardiovascular disease. Although caffeine can be refreshing, excessive intake can also lead to high blood pressure.

2. People with stomach problems drink little or no coffee as much as possible. Coffee will stimulate the gastric mucosa and lead to the deterioration of stomach disease.

3, pregnant women do not drink too much coffee, coffee will affect the absorption of iron, the incidence of iron deficiency anemia during pregnancy is higher, often drinking coffee will aggravate the problem of anemia.

4. Do not drink coffee within 6 hours before going to bed, and tea drinking should be the same. Drinking too much coffee will lead to tachycardia and excitement, insomnia, nervous disorders and other symptoms.

5. It is appropriate to drink no more than 2 cups of coffee a day. If you drink 4-5 cups of coffee continuously, it will cause nausea and stomach discomfort.

6. it is suitable to drink after meals. Drinking coffee on an empty stomach will promote gastric juice secretion, which is not suitable for patients with stomach diseases. Drinking after meals contributes to the digestion of food.

On a moderate level, moderate consumption of coffee is also beneficial:

Prevent allergies

Caffeine can stimulate and excite the sympathetic nerve, so drinking a cup of coffee can help prevent allergies. When allergies and asthma are about to occur, drinking a cup of coffee in advance can not only make use of the exciting effect of caffeine, but also can be psychologically adjusted.

Take care of skin

Caffeine can accelerate the metabolism of skin, dilute the dark circles under the eyes caused by non-circulation of blood, maintain the replenishment of the skin by antioxidation, delay aging, and so on.

Promote intestinal peristalsis

The content of soluble dietary cellulose in coffee is very high, which can accelerate gastrointestinal peristalsis. Women with mild constipation can also drink coffee to relieve constipation.

Relieving alcohol

Drinking coffee after drinking alcohol will quickly oxidize the acetaldehyde converted from alcohol, decompose it into water and carbon dioxide and discharge it out of the body.

Eliminate fatigue

Caffeine has a stimulating and exciting effect on the sympathetic nerve, so drinking a cup of coffee can help to eliminate fatigue. Of course, supplementary nutrition and adequate sleep are also better ways to eliminate fatigue.

Coffee has its advantages and disadvantages, so don't drink too much coffee on the spur of the moment. Too much can lead to danger in many cases. So whether you like it or not, drinking in moderation is the most reasonable.
