Can Drinking Coffee Really Fight Cancer? Does drinking coffee really fight aging?

Coffee is a popular drink, and there are many legends that coffee has other miraculous effects. Some people say it's particularly good and can prevent tumors. Some people say that it has the potential to cause tumors.

I always hear people around me: today an expert says this, tomorrow an expert says that, can you drink coffee? Is it good or bad?

Because the International Agency for Research on Cancer (IARC) under the World Health Organization classifies the carcinogenic risk of coffee as category 2B, which means that it may cause cancer to humans. So in previous years, some headlines could be seen on ** like this - "Coffee is also cancer-inducing". But now coffee lovers can put their hearts in their stomachs, because the IAC recently reduced the carcinogenic risk of coffee to category 3 in its guidelines, which means that there is not enough evidence that coffee is associated with cancer risk.

Don't be too happy too soon, don't just grab the hot coffee you have and drink it, and listen to me. The guidelines also state that hot beverages (including hot coffee) over 65 are likely to cause cancer, especially esophageal cancer.

The carcinogenic risk of hot beverages above 65 (including coffee) is classified as Category 2a, which is one notch higher than the previous level of coffee.

This must have been something that no one expected. Therefore, it is recommended that you do not eat any drink too hot, especially when it is just out of the pot, because there is a high incidence of esophageal cancer. Whether it is food or drink, it is better to eat it before eating it cold, it is best to eat it under 65.

Does drinking coffee really cause cancer? Experts answer for you.

Drinking coffee is generally anti-aging, but it should be done in moderation and not too much at one time.

Drinking coffee in moderation can not only play a role in refreshing the brain, but also promote the body's metabolism, promote the peeling of the aging stratum corneum, and achieve the anti-aging effect to a certain extent. However, it is not recommended to drink too much coffee, coffee contains caffeine, drinking too much may affect the quality of sleep, and it is easy to accelerate the aging after staying up late for a long time.

Usually to strictly control the personal diet, you can eat more collagen-rich foods, which can increase the elasticity.

The reason why many people choose him now, more often because he has more advantages, there are many benefits to the human body, coffee was originally a foreigner's drink, since coffee entered our country, so that more and more Chinese people fall in love with it, and its consumption is increasing by 30% per year, it can be seen that the demand for coffee is still quite large.

1. It has the role of **.

Now there are studies that show that drinking coffee can accelerate fat burning, and this is because coffee contains two components, caffeine and chlorogenic acid. Caffeine can speed up the body's metabolism and help the pancreas secrete lipase, which helps to break down fat and achieve the effect of burning fat. Chlorogenic acid is a polyphenol that can promote lipid metabolism, prevent fat accumulation in the body, and burn fat to achieve the best effect.

2. Keep people awake.

Many people think of coffee as "food for thought" because it contains caffeine, a substance that keeps people awake at all times. When a person feels tired, there is a substance called "adenosine" in the body, which acts on the neurotransmitter pathway of the "adenosine receptor" in the brain, making it easy to make people want to sleep. Caffeine blocks adenosine, which causes drowsiness, and keeps people awake.

Therefore, there are many people who drink coffee specifically to achieve a refreshing effect, so that they will not get tired at work and reduce the chance of mistakes.

3. Drinking coffee is good.

Drinking coffee can accelerate metabolism, can also promote the metabolism of the skin, help ** discharge aging keratin, lighten spots, dark circles, wrinkles, etc. Coffee also has a strong antioxidant effect, so female friends can drink some coffee appropriately, which can keep the skin alive, prevent cell aging, and fight aging.

Regular coffee drinking is not good, and the World Health Organization has removed coffee from the list of 2b carcinogens and moved it to category 3 (which is inconclusive and cannot be classified). However, the World Health Organization has also assessed that overheated beverages (over 65) are group 2A carcinogens and are likely to cause cancer.

Can cancer patients drink coffee during the ** period? I'm sure many people have questions about this!

The answer is yes.

During chemotherapy, when the drug is injected into the body to fight tumors, it is excreted mainly from the feces or through the kidneys in the urine. Therefore, the more urine output, the faster the drug is excreted through the urine, the faster the concentration of the drug in the blood decreases, and the shorter the maintenance time, the less uncomfortable the symptoms are caused by it, and it is usually recommended that the fluid intake varies from about 1500 to 3000 ml per day (the actual intake also needs to consider the patient's heart, lung, liver, kidney function and external environment). Of course, these liquids are not limited to drinking plain water.

If you experience loss of appetite or a change in your sense of taste, it is also a good choice to choose coffee, juice or tea instead of plain water to achieve your daily target of liquids.

Li Songqin, president of the Asia-Pacific Society of Oncology and Chronic Disease Nutrition, explained that if coffee is easy to cause palpitations, diarrhea or nausea, it is recommended to choose decaf drinks, such as herbal tea. In addition, because some chemotherapy drugs will affect the quality of sleep and cause insomnia, if you have this condition, it is not suitable to drink coffee before going to bed, so as not to aggravate this condition, and then reduce the quality of life. It is advisable to ask your oncologist or medical team if you are able to consume the coffee in moderation.

Adding milk, soy milk or nutrients to coffee not only provides aroma but also increases calorie intake. Cancer patients are reminded that if they add milk or soy milk to their coffee, they can brew an appropriate amount at one time and drink it as soon as possible to avoid the growth of bacteria in the food at room temperature.

It is said that coffee is carcinogenic because coffee contains acrylamide. The risk of cancer occurs when the human body consumes between micrograms and 16 micrograms of acrylamide per kilogram of body weight per day. Based on this calculation, a person weighing 55 kg would have a daily acrylamide tolerance of 143 micrograms.

A 160ml cup of coffee has an average acrylamide content of micrograms, and it takes at least 318 cups a day to pose a carcinogenic risk.

Is it true that drinking coffee causes cancer?

Starbucks coffee was found to contain high concentrations of carcinogenic chemicals - acrylamide, which is carcinogenic, so it can only be said that drink it sparingly.

Acrylamide is a white crystalline chemical with potential neurotoxicity, genotoxicity and carcinogenicity, and acrylamide is easily produced by carbohydrate-rich foods when cooked at high temperatures (greater than 120 °).

In fact, the coffee beans themselves do not contain acrylamide, nor are they added by Starbucks, but occur naturally during the roasting process, and all coffee will contain this substance.

Coffee beans are rich in starch, and after roasting and grinding, a certain amount of acrylamide will be produced (the content is equivalent to that of fried chicken thighs), but in order to improve the flavor of instant coffee, high-temperature (140 180) extraction methods are often used in the process of making instant coffee, which increases the acrylamide content several times.

In addition, we are often exposed to acrylamide in our daily lives through cigarette smoke and food. The acrylamide in food mainly includes baked goods, fried foods, puffed foods, etc., including instant coffee, boxed potato chips, french fries, bread, fritters, steamed buns, roasted sweet potatoes, roasted vegetable and fruit slices, salt-baked nuts, etc., covering almost most of the snacks in life.

The concentration of acrylamide in coffee is very low.

The World Health Organization's International Agency for Research on Cancer (IARC) has now classified acrylamide as a group 2 carcinogen (2a), and the current research is only at the stage of animal experiments (a large number of animal experiments have shown that acrylamide has certain carcinogenicity; And it can cause nervous system damage, affect early infant development, and endanger male reproductive health), there is no sufficient evidence that it has the same harm in humans, therefore, except for some special occupational groups may cause nerve damage due to large doses of exposure and ingestion, normal people do not need to worry too much.

Gao Yun, a dietitian at the Department of Nutrition of Shanghai Tongji Hospital, said that long-term and excessive consumption of foods containing acrylamide may indeed induce cancer, but for daily coffee drinking, there is no need to panic, "Acrylamide is a by-product of coffee beans after roasting, but a cup of instant coffee, whether it is handmade or bagged, the coffee content is only about 2 3 grams, and the data show that each kilogram of instant coffee contains about milligrams of acrylamide, which is almost half of that of potato fried food, and the actual concentration is actually very low." At the same time, some studies have shown that some ingredients in coffee may even reduce the risk of some cancers, so it is really biased to deny the verdict because the coffee contains acrylamide.

Recently, whether you drink coffee or not, you may have heard the so-called "Starbucks coffee causes cancer". The reason is that the judgment of the Los Angeles Superior Court in California showed that coffee contains acrylamide, a carcinogen, and requires all coffee products to be labeled "carcinogenic".

Hong Guangyu, a senior person in the field of food safety, said that the California court required coffee sold in the state to be labeled with a carcinogenic warning, on the grounds that the acrylamide contained in the coffee is listed as a "more likely carcinogen" in Class 2A by the International Agency for Research on Cancer (IARC), and its full meaning should be "limited evidence of carcinogenicity to humans and sufficient evidence of carcinogenicity to experimental animals". The list of carcinogens listed by the IRC refers to the strength of the evidence, not the "carcinogenic risk" of the substance.

Hong Guangyu explained that acrylamide is naturally formed when coffee beans are roasted and is key to the formation of coffee aroma, and its content in coffee is extremely low. Acrylamide does have clear evidence that it causes cancer in animals, but there is no scientific evidence for whether acrylamide causes cancer when ingested as an ingredient in food, and there is no epidemiological investigation to prove that it causes cancer.

Pros and cons of drinking coffee.

The main stimulant contained in coffee is caffeine. In addition, it contains fats and minerals such as magnesium, potassium, and copper, as well as B vitamins, aromas, and toxins. That said, coffee doesn't have any nutritional value, but it has many pros and cons on the body due to the effects of caffeine.

1.Beneficial effects of drinking coffee on the body:

For the nervous system: Caffeine has the effect of stimulating the brain, can eliminate the feeling of laziness, make people feel relaxed and happy, can make people concentrate, think quickly and evoke memory. Caffeine has been shown to speed up calculations and computers, and can make car drivers move quickly.

But there is no scientific evidence to prove that caffeine has an effect on improving the quality of work.

For cardiovascular: Drinking coffee can increase the heartbeat, increase blood pressure, promote blood circulation, and enhance myocardial contraction.

For the urinary system: caffeine can dilate the blood vessels of the kidneys and increase the blood flow of the glomeruli, thus increasing the water penetration and detoxification function of the kidneys, which can be said to have a diuretic effect.

For the respiratory system: Caffeine relaxes the smooth muscles around the trachea, which dilates the trachea and increases the volume of breathing. However, caffeine should not be used as a drug for clinical ** asthma.

2.Effects of Coffee Drinking on Physical Ills:

Drinking a lot of coffee can affect appetite and may cause vomiting and cramps, as well as gastritis and a thick tongue coating, which can make the body feel tired and weak.

Drinking a lot of coffee increases urine output, harms the bladder, and may cause urinary tract infections.

Too much caffeine in the body has a negative effect on the nervous system, causing insomnia, shaking hands, and slurred speech.

The latest research shows that when breastfeeding women drink coffee, caffeine can enter the child's body with the milk, making the child irritable and unable to sleep.

Coffee is a risk factor for those with heart disease and high blood pressure. Studies done in the United States have shown that drinking coffee can worsen heart disease and high blood pressure. The daily intake of caffeine must be controlled within 200 mg, that is, no more than 3 cups of coffee per day.

Coffee should never be given to children, and you are advised not to give coffee to teenagers under the age of 15. Try not to drink coffee or drink less coffee after the age of 40. The latest animal experiments suggest that caffeine may be a carcinogenic factor.

Breastfeeding women should not drink coffee.

The main components of coffee are: caffeine, tannins, fats, acidic fats, volatile fats, proteins, sugars, fibers, and minerals (containing small amounts of lime, iron, phosphorus, sodium carbonate, etc.).

The composition of coffee alone does not contain carcinogens, but medical research has proved that drinking too much coffee is carcinogenic to normal people, and it is not advisable to smoke immediately after drinking coffee, and some ingredients in coffee are combined with cigarettes to produce carcinogens, such as: phenylpropylene, arsenic, cadmium, methylhydrazine, aminophenol, etc., these substances have carcinogenic effects.
