This article takes a detailed look at nine of the most well-documented health advantages of drinking coffee.

This is due to the fact that caffeine inhibits the receptors for a neurotransmitter known as adenosine, which results in an increase in the amounts of other neurotransmitters in your brain that govern your energy levels, such as dopamine, in your brain ( 2 , 3 ).

Similarly, a research conducted on golfers found that drinking caffeine before and during a round of golf boosted performance while simultaneously increasing subjective energy levels and decreasing sensations of exhaustion ( 5 ).

According to some study, drinking coffee on a daily basis may be connected with a lower risk of acquiring type 2 diabetes over the long run.

  • According to current thinking, this is due to coffee’s capacity to maintain the function of the beta cells in your pancreas, which are responsible for creating insulin to manage blood sugar levels ( 7 ).
  • Summary Over the long run, it is possible that regular coffee drinking is associated with a decreased risk of acquiring type 2 diabetes.
  • According to a review of 13 studies, people who consumed caffeine on a regular basis had a significantly lower risk of developing Parkinson’s disease than those who did not.
  • Another review of 11 observational studies in more than 29,000 people also found that the more coffee people consumed, the lower their risk of Alzheimer’s disease ( 10 ).
  • Additionally, some studies have suggested that moderate coffee drinking might be related with a decreased risk ofdementiaand cognitive deterioration ( 11 , 12 ).

According to one review of seven studies, each cup of coffee people consumed per day was linked to an 8 percent lower risk of depression ( 17 ).

Another study found that drinking at least four cups of coffee each day was associated with a significantly lower risk of depression, compared with drinking just one cup per day ( 18 ).

What’s more, one study in more than 200,000 people showed that drinking coffee was linked to a lower risk of death by suicide ( 19 ).

Summary Several studies have found that coffee could be linked to a lower risk of depression and may even be linked to a lower risk of death by suicide.

For instance, one study found that drinking more than two cups of coffee per day was linked to lower rates of liver scarring and liver cancer in people withliver disease( 20 ).

Other research shows that the more coffee people drank, the lower their risk of death from chronic liver disease.

What are the top health benefits of drinking coffee?

Your cup of joe provides you with advantages that go beyond an energy boost. The following are the most significant ways that coffee can benefit your health:

You could live longer.

  • Recent research has discovered that women who consume coffee are less likely to die from several of the main causes of mortality in women, including coronary heart disease, stroke, diabetes, and renal disease
  • And

Your body may process glucose (or sugar) better.

  • That is the hypothesis driving studies that have discovered that those who consume more coffee are less likely to develop type 2 diabetes.

You’re less likely to develop heart failure.

  • It has been suggested that drinking one to two cups of coffee a day will help prevent heart failure, which occurs when a weak heart has trouble pumping enough blood to the body.

You are less likely to develop Parkinson’s disease.

  • The use of caffeinated beverages is not only associated with a decreased risk of acquiring Parkinson’s disease, but it may also assist people suffering from the illness in better controlling their movements.

Your liver will thank you.

  • Coffee, both normal and decaf, appears to have a protective impact on the liver’s function. In accordance with the findings of research, persons who regularly consume coffee have liver enzyme levels that are within a healthy range as opposed to those who do not.

Your DNA will be stronger.

  • Dark roast coffee reduces DNA strand breakage, which occurs naturally but can lead to cancer or tumors if not repaired by your cells
  • It also helps you lose weight.

Your odds of getting colon cancer will go way down.

  • Colon cancer affects one in every 23 women. However, researchers discovered that coffee consumers, whether they drank decaf or regular, were 26 percent less likely to acquire colon cancer.

  • An elevated heart rate, elevated blood pressure, anxiety, and difficulty falling asleep are all symptoms of hypertension.

So, what is the best quantity of coffee to consume in order to reap all of the advantages while avoiding the bad side effects? Dietary Guidelines for Americans state that most women may have three to five cups of coffee per day with a maximum caffeine intake of 400 mg without experiencing any negative consequences. (The amount of caffeine in a cup of coffee varies based on the kind, but an average 8-ounce cup has 95 mg.) The restrictions, however, are different if you are pregnant or nursing a child.

If coffee gives you the jitters, be careful not to drink too much of it at once: Everyone has a varied level of tolerance to caffeine.

Also, keep in mind that the ingredients you choose to create your coffee might have an impact on how nutritious the beverage is overall.

As an alternative to smothering your baked goods with cream and sugar, consider using up to two tablespoons of milk (or milk replacement) or half-and-half, as well as spices and flavorings that are naturally sweet. To add a little additional flavor, try stirring in a 14 teaspoon of the following:

While coffee is an enjoyable part of your lifestyle, there are other aspects that have a greater influence on your health, such as eating a well-balanced diet, exercising, and keeping a healthy body weight, among other things. Drinking coffee, on the other hand, is a pleasurable complement to those important health considerations. Nutritionists at Johns Hopkins University present a recipe for a nutritious iced pumpkin spice “latte” smoothie.

Is coffee good or bad for your health?

Despite the fact that early studies on coffee showed that it may cause health concerns, modern study has found compelling evidence that drinking coffee has a number of health advantages. On April 5, 2021, Discover magazine published an article by Frank Hu, chair of theDepartment of Nutrition at the Harvard T.H. Chan School of Public Health, who stated that “the overall data has been quite persuasive that coffee has been more helpful than hazardous in terms of health outcomes.” “Moderate coffee drinking can be accommodated into a healthy diet for the majority of people,” says the author.

  1. It’s even feasible that those who consume coffee can lower their chances of dying prematurely.
  2. Hu, on the other hand, pointed out that many of the individuals in those trials also smoked, which may have caused researchers to believe that coffee was to blame for the negative consequences that are now associated with cigarettes.
  3. According to him, “in the past, I believe many people believed, ‘Oh, coffee is so good, there must be something wrong with coffee,'” he explained.
  4. There is little information available on the effects of coffee on children, and caffeine may be detrimental to expectant mothers.
  5. Drinking coffee with a paper filter is recommended by doctors because unfiltered coffee is related with a higher risk of early mortality and can include substances that elevate levels of LDL, or “bad,” cholesterol in the bloodstream.

Coffee health benefits: Diabetes, heart health, liver cancer, and more

When people think of coffee, they typically associate it with its potential to deliver an energy boost to those who consume it. Research has discovered that it may also provide some crucial health advantages in addition to those mentioned above. The risk of liver cancer, type 2 diabetes, and heart failure may be reduced as a result of these advantages. Experts estimate that individuals throughout the world consume around 2.25 billion cups of coffee every day. Scientists have investigated whether drinking coffee can help prevent or treat a variety of health diseases such as type 2 diabetes, coronary artery disease, inflammatory bowel disease, and liver disease.

In addition to riboflavin (vitamin B2), niacin (vitamin B3), magnesium, potassium, and a variety of phenolic compounds (antioxidants), coffee has a number of other minerals that are beneficial.

This article examines the potential health advantages of drinking coffee, as well as the data that supports those benefits, as well as the hazards associated with coffee use.

Consumption of coffee may also be beneficial to one’s cardiovascular health.

Coffee and diabetes

Coffee may be beneficial in the prevention of type 2 diabetes. Those who raised their coffee consumption by at least one cup per day over four years had an 11 percent reduced chance of developing type 2 diabetes than those who did not increase their intake, according to a 2014 study included data from over 48,000 participants. According to the findings of a 2017 meta-analysis, those who consumed four to six cups of either caffeinated or decaffeinated coffee each day tended to have a reduced risk of metabolic syndrome, which includes type 2 diabetes, than those who did not.

Coffee and Parkinson’s disease

Several studies have shown that caffeine, which may be found in coffee and many other beverages, may be beneficial in the prevention of Parkinson’s disease in certain people. Men who drink more than four cups of coffee each day, according to one study, may have a fivefold reduced chance of developing Parkinson’s disease than men who do not drink coffee. The findings of a meta-analysis published in 2017 revealed a relationship between coffee drinking and a decreased risk of Parkinson’s disease, even in persons who do not smoke cigarettes.

However, there was insufficient data to support the claim that consuming decaffeinated coffee can help prevent Parkinson’s disease from developing.

Coffee and chronic liver disease or cancer

A evaluation of the research published in 2019 showed that coffee use is likely to lower the risk of liver cancer. Earlier, in 2015, a cohort study of a multiethnic population in the United States found that drinking two to three cups of coffee daily, depending on the dose, reduced the participants’ risk of developing hepatocellular carcinoma and chronic liver disease (CLD) by 38 percent and 46 percent, respectively, compared to those who did not drink coffee. According to the findings of a meta-analysis published in 2017, drinking any sort of coffee appears to lower the risk of liver cancer, nonalcoholic fatty liver disease, and cirrhosis.

More information on the 2021 study on coffee and liver illness may be found here.

Coffee and other liver diseases

In addition, those who drink coffee may be at a decreased risk of developing gallstone disease. People with primary sclerosing cholangitis (PSC) and primary biliary cirrhosis (PBC) consumed more coffee in 2014, according to a study conducted by experts (PBC). autoimmune diseases that affect the bile ducts of the liver They discovered that persons who had PSC were more likely than those who did not to have the illness to have a lower coffee intake. There was no evidence to imply that coffee consumption differed between those who had and did not have PBC.

According to the researchers, consuming two or more cups of coffee per day might cut the risk by as much as 66 percent in some cases.

Coffee and heart health

According to the findings of a 2017 meta-analysis, caffeine use may have at least a little advantage for cardiovascular health, including lower blood pressure. According to the findings of a 2018 study, consuming three to five cups of coffee a day may cut the risk of cardiovascular disease by 15 percent. Drinking one to five cups of coffee per day seems to be connected with a decreased overall mortality rate, regardless of the cause of death. Coffee consumption does not appear to raise the likelihood of having another heart attack or dying as a result of a previous heart attack in individuals who have previously had one.

These drugs have the potential to predispose a person to heart disease.

Coffee and obesity

There is some evidence to suggest that drinking coffee might assist people in losing weight. According to one study published in 2018, the more the amount of coffee consumed by individuals, the greater the mean reduction in weight, body mass index (BMI), and fat mass. The results of a 2019 study revealed that consuming coffee may be associated with weight reduction, with the link being stronger in males than in women, according to the findings. However, because these findings have not been reproduced, they may not be considered conclusive.

  1. Approximately 3.3 ounces of normal black coffee (without milk or cream) has just 100 milliliters (approximately 3.33 ounces) of calories.
  2. Adding milk or sugar, on the other hand, will boost the calorific value.
  3. Antioxidants can aid in the protection of the organism against the effects of free radicals.
  4. Free radicals operate as poisons in the body, and they have the potential to trigger inflammation.
  5. As recently as 2018, several studies hypothesized that the antioxidant content of coffee might provide protection against the metabolic syndrome.

Despite the fact that scientists have demonstrated that some molecules are present in coffee beans, it is still unclear what happens to them once they reach the body of a human. Drinking excessive amounts of coffee might also have negative consequences. The following are examples of such items.

Bone fractures

Women who consume large amounts of coffee, according to some research, may be at greater risk of bone fractures than males. Men who consume more coffee, on the other hand, appear to be at a little decreased risk of developing prostate cancer.

Complications during pregnancy

It is also possible that coffee drinking is unsafe during pregnancy. In fact, there is some evidence to show that excessive coffee drinking is associated with pregnancy loss, low birth weight, and premature birth.


Women who consume large amounts of coffee may be at increased risk for endometriosis, however there is little data to support this hypothesis.

Gastroesophageal reflux disease

People who consume large amounts of coffee may be at a slightly increased risk of developing this illness.


People suffering from panic disorder or social anxiety disorder may find that consuming large quantities of coffee increases their likelihood of developing an anxiety condition. Caffeine has been shown to cause mania and psychosis in people who are vulnerable to it, however this is rare.

Mental health conditions

The findings of a study conducted in 2016 suggested that excessive caffeine use throughout adolescence might result in irreversible abnormalities in the brain. It is the scientists who conducted the study who are concerned that this might raise the likelihood of developing anxiety-related illnesses in later life.

Exposure to toxic ingredients

In 2015, a group of researchers discovered that commercial coffee had rather high amounts of mycotoxins. Mycotoxins are poisonous chemicals that may infect coffee, which is a naturally occurring material. Another chemical found in coffee, acrylamide, has prompted some people to express concern about its potential harm. More information may be found here. Although caffeine use has been shown to have certain advantages, taking too much of it can have harmful side effects. These are some of the possible negative effects:

  • Interactions with certain medicines, such as some psychiatric meds, thyroid medications, heartburn medications, and antibiotics
  • Adverse interactions with other medications
  • It is likely that women who take more than 300 milligrams (mg) of caffeine per day and do not ingest adequate calcium will experience spinal bone loss. When someone consumes a large amount of coffee during pregnancy, it can cause gastrointestinal problems, an increase in blood pressure, and an increase in the risk of myocardial ischemia, which is a type of heart disease
  • When someone consumes a large amount of coffee while breastfeeding, it can cause irritability and insomnia in nursing infants
  • And when someone consumes a large amount of coffee during pregnancy, it can cause fertility difficulties, a decrease in the risk of myocardial ischemia, which However, this is not definite, and it is possible that it is confined to excessive caffeine consumption. Symptoms of some mental health problems, such as schizophrenia or bipolar disorder, are exacerbated
  • The risk of suicide is elevated
  • And coffee-specific diseases, which include the following:
  • Among the disorders associated with caffeine are caffeine intoxication (or overdose), anxiety disorder caused by caffeine, sleeplessness caused by caffeine, and a caffeine-related condition that is not otherwise described.

Due to the fact that coffee and tea both contain caffeine, they may have some of the same health advantages, dangers, and side effects as one another. However, while the quantity of caffeine in each beverage might vary depending on the type of coffee or tea consumed, one 8-ounce cup of coffee typically contains around 95 mg of caffeine on average. In comparison, the caffeine content of a cup of black tea and a cup of green tea is just 48 mg and 29 mg, respectively. According on which beverage a person prefers and how much of it they eat, there may be some variances in how drinking tea and coffee may effect different people.

The findings revealed that the advantages of coffee and tea consumption varied in the following ways: The overall result of the study is that both coffee and tea have their own set of advantages that vary depending on how much is taken, and that these benefits may differ between men and women as well.

According to the findings of a meta-analysis published in 2017, it is “usually safe” for the majority of individuals to consume three to four cups of coffee per day, and that doing so may actually lower the chance of developing certain health disorders.

Although caffeine is a significant component of coffee, the beverage contains a variety of other substances and can be consumed in a variety of ways.

When it comes to coffee drinking, those who want to reap the health advantages should avoid exceeding the daily suggested intake and should keep an eye on the substances they use — such as sugar, cream, and flavorings — since they may be detrimental to their health.

Caffeine should be avoided by pregnant women and anyone who are at risk of bone fractures.

The Health Benefits of Coffee

Coffee is quite popular in the United States. The fact that practically every local coffee shop that offered takeout coffee managed to stay open during the epidemic that shut down New York last spring was a source of amazement to me, as did the number of folks who ventured out to start their stay-at-home days with a beloved store-made brew. One elderly acquaintance who was preandemic had traveled by train from Brooklyn to Manhattan to get her favourite mix of ground coffee and had arranged for it to be delivered to her home.

  • For coffee, I rely on machine-brewed pods, and last summer, when it was relatively safe for me to go shopping, I purchased a year’s supply of the mixes I enjoy.
  • The most recent studies on the health consequences of coffee and caffeine, its primary active element, are comforting in their conclusions.
  • In reality, according to several studies done across the world, drinking four or five eight-ounce cups of coffee (or approximately 400 milligrams of caffeine) each day has been shown to be connected with a lower mortality rate.
  • The most striking finding was a 50 percent reduction in the risk of suicide among both men and women who drank modest amounts of coffee, which may have been caused by an increase in the synthesis of brain chemicals that have antidepressant properties.
  • I’ve been subjected to intermittent health warnings about coffee for decades, and I’ve never been convinced.
  • Although coffee has been linked to cancer since at least 1991, the World Health Organization still considers it to be so.
  • In the words of Dr.

Caffeine penetrates the placenta and enters the fetus, and drinking coffee while pregnant can raise the chance of miscarriage, low birth weight, and early birth, among other complications.

When it comes to caffeine-infused beverages, sleep disruption is the most prevalent negative side effect.


He admitted that he “was sleeping like a teenager again” after completing the difficult chore of weaning himself off of coffee for a period of time.

Willett, who is now 75 years old, stated that “you don’t have to go to zero intake to minimize the influence on sleep,” although he did agree that a person’s sensitivity to caffeine “probably rises with age,” according to the National Sleep Foundation.

However, even if you are able to go asleep easily after an evening cup of coffee, according to Michael Pollan’s new book, “This Is Your Mind on Plants,” it may interfere with your capacity to acquire proper deep sleep.

Willett, may be overcome by developing a certain level of tolerance.

Although caffeine has many benefits, developing a tolerance to it might diminish those benefits if, for example, you want to be awake and focused while driving or taking a test.

Caffeine is one of these substances.

Polyphenols have been shown to limit the growth of cancer cells and reduce the chance of Type 2 diabetes; antioxidants, which have anti-inflammatory properties, have been shown to combat both heart disease and cancer, which are the two main causes of death in the United States.

When coffee is prepared without the use of a paper filter, such as in the French press, Norwegian boiling coffee, espresso, or Turkish coffee, fatty compounds known as diterpenes are released, which can boost LDL cholesterol levels, which are harmful to the heart.

Knowing that I had a high cholesterol level, I disassembled a coffee pod and discovered a paper filter covering the plastic cup within.

Popular coffee additives such as cream and sweet syrups, which may turn a calorie-free beverage into a calorie-dense treat, might also work against the potential health advantages of coffee, according to research.

The sugar content of a 16-ounce Starbucks Mocha Frappuccino is 51 grams, the fat content is 15 grams (ten of which are saturated fats), and the calorie count is 370.

Cold brew coffee, which is becoming increasingly popular, counteracts the natural acidity of coffee as well as the bitterness that emerges when boiling water is poured over the grounds.

Iced coffee may be made with decaffeinated coffee as well as regular.

Decaf does not have a negative impact on one’s health entirely. As with caffeinated coffee, the polyphenols found in green tea have anti-inflammatory qualities that may help to reduce the incidence of Type 2 diabetes as well as some cancers.

Coffee Health Benefits: Research on Type 2 Diabetes, Cancer, Stroke, and More

Despite the fact that coffee is delicious and may pull you out of bed in the morning, what does it do for your overall health? Researchers are discovering that coffee consumers have a number of advantages over nondrinkers, including:

  • Type 2 diabetes, Parkinson’s disease, and dementia are all less likely to occur. having a lower incidence of certain malignancies, heart rhythm problems, and strokes
  • And

The Harvard School of Public Health’s Frank Hu, MD, MPH, PhD, is a nutrition and epidemiology professor who specializes in coffee and health. “There is clearly more good news than negative news when it comes to coffee’s effect on health,” he says. However (you were expecting there to be a “but,” weren’t you?) Coffee has not been shown to be effective in preventing such conditions. Researchers do not advise people to refrain from drinking or skipping coffee only for the sake of scientific investigation.

Those research are unable to demonstrate cause and effect.

As a result, there is no conclusive evidence.

For those of you who consume 416 8-ounce cups of coffee on average every year (according to the World Resources Institute), you might be curious about what all of that java is doing for or to your health.

Type 2 Diabetes

Hu describes the evidence on coffee and type 2 diabetes as “very good,” citing more than 15 research that have been published. According to the researchers, “the great majority of those trials have demonstrated that coffee can help avoid diabetes.” According to Hu, a spokesperson for WebMD, “there is now evidence suggesting decaffeinated coffee may provide the same benefits as normal coffee.” In 2005, Hu’s team conducted a review of nine research on the relationship between coffee and type 2 diabetes.

  • People who consumed 4-6 cups of coffee each day saw a lesser benefit – a 28 percent decreased chance of developing cancer.
  • or Europe).
  • They discovered that for every additional cup of coffee consumed daily, the likelihood of developing type 2 diabetes decreased by 7%.
  • However, the researchers emphasized that the data from some of the smaller studies they analyzed may be less credible than the data from larger studies.
  • What role does coffee play in keeping diabetes at bay?
  • “We already know that coffee has a very high antioxidant capacity,” Hu explains further.
  • Type 2 diabetes is characterized by the body’s inability to efficiently utilise insulin and manage blood sugar levels.

However, it is most likely not the caffeine. According to Hu, based on research on decaf coffee, “I believe we can fairly conclude that the advantages are not likely to be related to caffeine.”

Hold the Caffeine?

According to James D. Lane, PhD, professor of medical psychology and behavioral medicine at Duke University Medical Center in Durham, North Carolina, the fact that coffee contains beneficial compounds does not always imply that it is beneficial to humans. “It has not been demonstrated that coffee consumption results in an increase in antioxidants in the body,” Lane says in an interview with WebMD. “We know that coffee itself contains significant amounts of antioxidants, particularly when freshly brewed, but we don’t know if those antioxidants are released into the circulation and the body when a person consumes it.

According to Lane, caffeine can boost blood pressure as well as levels of the chemical epinephrine (commonly known as adrenaline), which is involved in fight-or-flight responses.

Heart Disease and Stroke

Coffee has been shown to reduce the risk of heart attack and stroke in a number of ways. First and foremost, there is the possibility of an increase in the risk of type 2 diabetes. Type 2 diabetes increases the likelihood of developing heart disease and stroke. Coffee has also been related to decreased risks for cardiac rhythm abnormalities (another risk factor for heart attack and stroke) in both men and women, as well as a lower risk for stroke in women. The findings of a study of approximately 130,000 Kaiser Permanentehealth plan members revealed that people who reported drinking 1-3 cups of coffee per day were 20 percent less likely to be hospitalized for abnormal heart rhythms (arrhythmias) than those who did not drink coffee, regardless of other risk factors, Additionally, coffee may lessen the chance of having a stroke in women.

It didn’t matter if the women had high blood pressure, high cholesterol levels, or type 2 diabetes; the pattern remained consistent.

Parkinson’s and Alzheimer’s Diseases

The research on Parkinson’s disease has always been consistent, according to Hu, who spoke to WebMD. “Higher intake of coffee is connected with a lower risk of Parkinson’s disease,” he says. According to Hu, this appears to be related to caffeine, however the specific mechanism by which it operates is unclear. Also associated with a decreased incidence of dementia, including Alzheimer’s disease, is coffee consumption. Researchers in Finland and Sweden found that, out of 1,400 people followed for approximately 20 years, those who reported drinking 3-5 cups of coffee daily were 65 percent less likely to develop dementia and Alzheimer’s disease than those who reported drinking less than one cup of coffee daily or only occasionally drank coffee were.


The evidence for coffee’s cancer-protective properties is poorer than the evidence for its type 2 diabetes-protective properties. “However, in the case of liver cancer, I believe that the data is highly consistent,” Hu explains. “All of the research have demonstrated that increased coffee intake is connected with a lower incidence of liver cirrhosis and liver cancer,” he explains.

Although Hu describes this as a “very exciting discovery,” it is not apparent how it may be put to use. Once again, this research indicates a probable correlation, but, like the majority of studies on coffee and health, does not demonstrate a causal relationship.


The American College of Obstetricians and Gynecologists (ACOG) published a statement in August 2010 stating that moderate caffeine consumption – less than 200 mg per day, or about the amount found in 12 ounces of coffee – does not appear to have any significant effects on the risk of miscarriage, premature delivery, or fetal growth during pregnancy. However, the consequences of higher caffeine dosages are unknown, and additional study suggests that pregnant women who consume several cups of coffee per day may be at greater risk for miscarriage than women who do not drink coffee or drink it in moderation during their pregnancy.

Calories, Heartburn, and Urine

You won’t go over your calorie allotment on coffee – at least not until you start adding the extras. One cup of black coffee comprises just 7 calories, according to the website myfoodapedia.gov, which is operated by the United States Department of Agriculture’s Center for Nutrition Policy and Promotion. With the addition of half-and-half, you’ll receive 46 calories. If you prefer a nondairy creamer in a liquid form, that will cost you an additional 48 calories. A teaspoon of sugar can add around 23 calories to your diet.

Caffeine is a moderate diuretic, which means that it causes you to pee more frequently than you would otherwise.

Coffee, both normal and decaffeinated, contains acids that might aggravate heartburn symptoms.
