Coffee and Caffeine — How Much Should You Drink?

Coffee has hundreds of bioactive chemicals that are beneficial to the body. In fact, for many people, it is their single most important source of antioxidants ( 1 , 2 ). Studies have also revealed that coffee consumers had a decreased chance of developing ailments such as type 2 diabetes, neurological problems, and liver disease ( 3 ). However, you may be wondering how much coffee is safe to consume and whether excessive consumption poses any concerns to your health. This article describes how much coffee you can consume without harming yourself.

  1. The amount of caffeine in a cup of coffee varies greatly, ranging from 50 to over 400 mg per cup.
  2. As a general guideline, you may expect that an ordinary 8-ounce (240-ml) cup of coffee has around 100 mg of caffeine on average.
  3. Many people, however, consume far more alcohol than that without experiencing any negative consequences.
  4. SUMMARYThe amount of caffeine in your morning cup of joe can range from 50 to more than 400 mg.
  5. If you consume an excessive amount of coffee in a short period of time, you may suffer mental and physical symptoms such as:
  • Restlessness, anxiety, dizziness, upset stomach, irritability, sleeplessness, rapid heartbeat, tremors
  • These are only a few of the symptoms.

It is possible that you are sensitive to caffeine if you experience these symptoms after drinking coffee. If this is the case, you should try reducing your caffeine consumption or eliminating caffeine entirely. While it is conceivable to die from a caffeine overdose, it is extremely unlikely to do so by drinking only coffee. Drinking more than 100 cups (23.7 liters) of water in a single day would be required. There have been a few reported incidents of people dying after using caffeine pills, although these are extremely rare ( 8 ).

  • Caffeine has a variety of effects on various people.
  • In addition to affecting the enzymes that break down caffeine in your liver, these genes also have an effect on the caffeine receptors in your brain.
  • Some people may drink coffee and fall asleep right away, but others are kept up throughout the night by the caffeine they consume.
  • The vast majority of people fall someplace around the center.
  • Others who consume coffee on a daily basis may handle far more than those who use it infrequently.
  • If you suffer from anxiety, panic disorder, cardiac arrhythmia, high blood pressure, diabetes, or any other medical condition, you may be able to handle caffeine at a lower level than usual.
  • SUMMARYS Caffeine sensitivity varies greatly from person to person and is influenced by genes and caffeine receptors in the brain.
  • It has also been linked to a longer life span in several studies.
  • Similar findings were supported by two other reviews ( 12 , 13 ).
  • According to a recent study, drinking four cups or more of coffee per day was associated with an increased — not a decreased — risk of mortality in those under the age of 55.
  • It’s important to note that neither these nor the majority of other studies clarify whether “cup” refers to a normal 8-ounce (240-ml) cup or just a generic vessel that individuals may use to drink coffee, regardless of its size.

In summary, although the data isn’t conclusive, multiple studies have found that coffee users live longer lives — with the best amount of coffee consumed each day being around 4–5 cups. Coffee has also been associated to a lower chance of developing a number of ailments, including the following:

  • Kind 2 diabetes is a type of diabetes that affects the pancreas. The greater the amount of coffee consumed, the lower the chance of developing type 2 diabetes. One research indicated that each daily cup of coffee reduced the risk of liver cirrhosis by 7 percent (
  • 15
  • ). When you drink 4 cups or more of coffee per day, you can reduce your risk of developing liver cirrhosis, which is a serious consequence of various liver illnesses (
  • 16
  • 17).
  • Cancer of the liver. Every two cups of coffee consumed everyday reduces your chance of developing liver cancer by 44 percent (18) Alzheimer’s disease is a kind of dementia. According to one research, drinking 3–5 cups of coffee per day was associated with a 65 percent lower risk of Alzheimer’s disease (
  • 19). Parkinson’s disease is a neurological disorder. Coffee consumption is connected with a lower incidence of Parkinson’s disease, with the largest reduction occurring when 5 cups or more are consumed per day (
  • 20
  • ).
  • Suicidal ideation. A recent study found that drinking 4 cups or more of coffee per day is associated with a 20 percent reduced risk of depression and a 53 percent lower risk of suicide (21, 22).

As a result, it appears that aiming for 4–5 cups of coffee per day is the best bet. Given that all of these studies were of an observational nature, it is impossible to conclude that coffee was responsible for the decrease in sickness – simply that coffee consumers were less likely to get certain illnesses. Nonetheless, it is important to keep these findings in mind. In most circumstances, decaf coffee should provide the same health benefits as regular coffee. The only exception appears to be Parkinson’s disease, which appears to be predominantly influenced by the caffeine in the beverage.

  1. Caffeine has been shown to penetrate the placenta and reach the fetus in pregnant women.
  2. A high intake of caffeine during pregnancy has been linked to an increased risk of miscarriage, stillbirth, early delivery, and low birth weight, according to some research ( 23 , 24 , 25 , 26 ).
  3. Many specialists, on the other hand, advise against drinking coffee at all during pregnancy.
  4. SUMMARYBecause of concerns regarding caffeine’s influence on the growing baby, it is generally suggested that pregnant women avoid or limit their coffee consumption while pregnant.
  5. In addition to having the lowest risk of early mortality, this quantity is associated with having a decreased risk of a wide range of prevalent illnesses, some of which impact tens of millions of people.
  6. This beverage should be avoided at all costs by those who are caffeine sensitive, suffer from specific medical problems, or just do not like for it.
  7. Furthermore, by simply adding sugar or other harmful, high-calorie additives to coffee, you may quickly nullify the advantages of the beverage.
  8. SUMMARYAccording to the evidence, drinking 4–5 cups of coffee per day is related with the largest number of health advantages.
  9. For those who prefer coffee, there is very little evidence of danger – and a plethora of studies demonstrating its health advantages.

While 4–5 cups of coffee per day is recommended, many people can drink much more than that without experiencing any difficulties. Unless you are experiencing negative side effects from drinking a lot of coffee, there is no need to quit drinking it altogether.

Caffeine: How much is too much?

Caffeine has many advantages, but it can also cause issues. Learn how much is too much and whether or not you need to reduce your usage. Staff at the Mayo Clinic If you rely on coffee to get you out of bed in the morning and keep you going throughout the day, you are not alone. Every day, millions of individuals rely on coffee to keep them awake and increase their attention levels.

How much is too much?

Most healthy persons appear to be able to consume up to 400 milligrams (mg) of caffeine per day without experiencing any adverse effects. Approximately the amount of caffeine contained in four cups of freshly ground coffee, 10 cans of cola, or two “energy shot” beverages. You should keep in mind that the actual amount of caffeine contained in beverages varies greatly, particularly among energy drinks. The Food and Drug Administration of the United States has warned that caffeine consumed in powder or liquid form can result in hazardous quantities of caffeine.

  1. Such high doses of caffeine can result in major health concerns, and even death, if not treated promptly.
  2. A warning should be sent to adolescents and young adults about excessive caffeine consumption as well as the dangers of combining caffeine with alcohol and other substances.
  3. Even in adults, excessive caffeine use might result in undesirable side effects.
  4. Continue reading to find out if you should cut back on your coffee intake.

You drink more than 4 cups of coffee a day

If you’re consuming more than 4 cups of caffeinated coffee a day (or the equivalent) and experiencing negative effects such as the following, you might consider cutting back.

  • Headache, insomnia, nervousness, irritability, frequent urination or difficulty to regulate urine, rapid heartbeat, muscle tremors, and other symptoms

Even a little makes you jittery

People react differently to caffeine depending on their genetic make-up. If you’re sensitive to the effects of caffeine, even tiny doses might cause unpleasant side effects such as restlessness and sleep issues in vulnerable individuals. The amount of caffeine you’re accustomed to consuming may have an impact on how you react to caffeine in general. People who do not routinely use caffeine are more susceptible to its effects than those who do.

You’re not getting enough sleep

Even in the afternoon, caffeine might have a negative impact on your sleep. Even little sleep deprivation can accumulate over time and impair your ability to stay alert and function well during the day. Caffeine use to alleviate sleep deprivation can lead to a vicious cycle of overindulgence. Drinking caffeinated beverages, for example, may be necessary if you are having difficulty staying awake during the workday. However, the caffeine prevents you from falling asleep at night, resulting in you sleeping for a shorter period of time.

You’re taking medications or supplements

There may be an interaction between caffeine and some drugs and herbal supplements. Examples include the following:

  • Ephedrine. This medicine, which is found in decongestants, may raise your risk of high blood pressure, heart attack, stroke, or seizure if you combine it with caffeine. This medicine, which is used to open up the bronchial airways, has been shown to produce caffeine-like effects in some people. Because of this, consuming Echinacea with caffeine may exacerbate the negative effects of caffeine, such as nausea and heart palpitations
  • Echinacea is a natural antibiotic. This herbal supplement, which is sometimes used to treat colds or other infections, may raise the concentration of caffeine in your blood, which may exacerbate the unpleasant effects of caffeine
  • Nevertheless, it is not recommended.

Consult with your doctor or pharmacist to determine whether caffeine may have an impact on your medicines.

Curbing your caffeine habit

Cutting back on caffeine may be difficult, whether it’s for one of the reasons listed above or simply because you want to save money on coffee beverages. Withdrawal symptoms such as headaches, weariness, irritability, and trouble concentrating on activities may occur if caffeine intake is reduced abruptly or stopped altogether. Fortunately, these symptoms are often moderate and subside within a few days of the onset. Try the following strategies to break your coffee addiction:

  • Keep an eye on things. Start keeping track of how much caffeine you’re consuming through foods and beverages, especially energy drinks. Pay close attention to the labeling. However, keep in mind that your estimate may be a bit low because certain foods or beverages that contain caffeine are not included on the label
  • Reduce the amount of time you spend on it gradually. Drinking one fewer can of soda or one fewer cup of coffee each day, for example, will help you lose weight. Alternatively, refrain from consuming caffeinated beverages late in the day. This will assist your body in becoming used to the reduced levels of caffeine and will reduce the likelihood of experiencing withdrawal symptoms. Make the switch to decaf. The majority of decaffeinated beverages have a similar appearance and flavor to their caffeinated counterparts. Reduce the brewing time or switch to herbal tea. When brewing tea, brew it for a shorter period of time. Its caffeine level is reduced as a result of this. Alternatively, look for herbal teas that are caffeine-free
  • Check the label. Caffeine is found in several over-the-counter pain medications, but not all of them. Instead, look for pain medicines that are caffeine-free.

The bottom line

When it comes to grownups, caffeine is likely to be a part of their daily routine. Generally speaking, it will not cause any health problems. However, be aware of the potential adverse effects of caffeine and be prepared to reduce your intake if required.

According to specialists at the Food and Drug Administration, caffeine may be a beneficial component of a balanced diet for the majority of individuals, but too much caffeine can be harmful to your health. Español Does your first cup of coffee or tea of the day include only a small amount of caffeine in the hopes that it would help you get through the rest of the day more quickly? Do you follow it up with a caffeinated beverage or two, and then go on to consume many more cups of coffee throughout the course of the day?

According to specialists at the Food and Drug Administration, caffeine may be a beneficial component of a balanced diet for the majority of individuals, but too much caffeine can be harmful to your health.

Learn more about caffeine by reading the questions and answers that follow.

1. Which kinds of foods and beverages contain caffeine?

In the plants that we use to create coffee, tea, and chocolate, caffeine may be found in their natural form. Additionally, it may be present in some plants that are used as flavorings, such as guarana, as well as in alternative South American teas, such as yerba mate (Ilex paraguariensis) andIlex guayusa (Ilex guayusa). Caffeine may also be used as an ingredient in a variety of food and beverage products.

2. How do you know how much caffeine a food or beverage contains?

Many packaged items, including beverages and nutritional supplements that contain caffeine, voluntarily disclose the amount of caffeine they contain on the label. This is done to protect consumers’ health. When consuming for the first time a new packaged product that has added caffeine, consumers should exercise caution, especially if the amount of caffeine in the meal is not specified on the packaging. Some foods and beverages, such as coffee and tea, contain high levels of caffeine, and there are various online databases that offer estimations of this content.

A 12 ounce can of caffeinated soft drink normally has 30 to 40 milligrams of caffeine, whereas an 8-ounce cup of green or black tea typically provides 30-50 mg, and an 8-ounce cup of coffee often includes 80 to 100 milligrams of caffeine.

3. If a coffee or tea says “decaffeinated,” does that mean it contains no caffeine?

No. Decaf coffees and teas have less caffeine than their normal equivalents, but they still include a small amount of the stimulant. For example, an 8-ounce cup of decaf coffee generally contains 2-15 mg of caffeine. In the event that you have a serious negative reaction to caffeine, you may wish to avoid drinking these beverages completely.

4. How much caffeine is too much?

The Food and Drug Administration (FDA) has determined that 400 mg of caffeine per day (equivalent to four or five cups of coffee) is a quantity that is not commonly linked with harmful or negative effects in healthy persons. There is, however, a great deal of diversity in how sensitive people are to the effects of caffeine, as well as in how quickly they metabolize it (break it down). Certain medical disorders, as well as certain drugs, might make people more sensitive to the effects of caffeine.

Although the Food and Drug Administration has not established a limit for children, the American Academy of Pediatrics recommends that children and adolescents avoid coffee and other stimulants.

5. How do you know if you’ve consumed more caffeine than you can tolerate?

Caffeine overconsumption can result in the following side effects:

  • Insomnia, restlessness, anxiety, rapid heart rate, upset stomach, nausea, headache, and a general sensation of discontent (dysphoria) are all possible symptoms.

6. Does caffeine pose a danger to your health?

According to the FDA, hazardous consequences such as seizures can be detected after consuming around 1,200 milligrams of caffeine, or 0.15 teaspoons of pure caffeine, in a short period of time. Pure and highly concentrated caffeine products pose a substantial concern to public health and have been linked to at least two deaths in the United States in recent years. (In April, the Food and Drug Administration (FDA) took measures to safeguard consumers from these items. Often marketed as dietary supplements, these products are made up of pure or highly concentrated caffeine in powder or liquid form.

The risk of caffeine overdose grows as the concentration of caffeine in the product increases, which means that even tiny doses of a highly concentrated product might result in hazardous side effects if taken in excess.

These are hazardous concentrations that can have major health repercussions, including death, if consumed in large quantities.

7. Is it okay for kids to consume caffeine?

We urge that you get guidance from your child’s health care practitioner regarding his or her caffeine usage.

8. Is drinking a lot of caffeine a substitute for sleep?

No. In addition to making you more alert and awake, caffeine is a stimulant that should not be used in place of sleep. Typically, it takes 4 to 6 hours for your body to digest half of the food you eat in a single sitting. As a result, a cup of coffee before supper may keep you awake at night.

9. How can I cut back on caffeine without causing unpleasant side effects?

You should reduce your caffeine intake gradually if you are used to drinking caffeinated beverages on a daily basis and wish to reduce your intake. The rapid cessation of a drug might result in withdrawal symptoms such as headaches, anxiety, and anxiousness. Caffeine withdrawal, in contrast to opioid or alcohol withdrawal, is not thought to be harmful, although it can be uncomfortable. You may wish to consult with your health-care practitioner about ways to reduce your consumption.

Does Coffee Count as Fluid?

“Keep hydrated” is one of those tried-and-true bits of dietary advice that you’ve heard your whole life but haven’t taken the time to implement. The results of a national study of 2,000 American adults, done by OnePoll for the brand Evian, revealed that less than one-quarter of respondents reported consuming eight or more glasses of water each day. What is it about all of those fluids that is so critical? As stated by the Centers for Disease Control and Prevention (CDC), they have a role in the regulation of body temperature as well as mood and cognitive function.

  • However, maintaining proper hydration might be difficult.
  • And the consequences of dehydration extend beyond the sensation of thirst.
  • In accordance with scientific research, cognitive function can be impaired even when physiological fluid levels are just 1 to 2 percent depleted.

Water vs. Coffee: How Do They Compare?

Given that normal coffee contains caffeine, which might have a mild diuretic effect, many people feel that coffee is dehydrating; however, this is not exactly the case. According to the Mayo Clinic, while drinking caffeinated coffee will produce a minor increase in urine outflow, it will not cause you to lose any more fluid than you are already losing via drinking the coffee itself. Having said that, you will not receive the same fluid benefit from tea as you would from water cup for cup. For example, according to a research published in September 2015 in the Journal of Science and Medicine in Sport, an average daily consumption of around 300 milligrams (mg) of caffeine resulted in a loss of approximately 15 percent of the fluid consumed.

Water, on the other hand, is still your best choice for having the bulk of your fluid requirements met each day.

Nutrition Facts of Coffee

Coffee is a low-calorie beverage that may be included in any balanced diet. According to the United States Department of Agriculture, an 8-ounce cup of black coffee has just two calories and no fat or carbohydrates (USDA). Some minerals are present in trace amounts (2 percent or less of the daily value) in the product, but not in sufficient quantities to be relevant. The antioxidants and polyphenols present in coffee beans are responsible for the majority of the health benefits associated with the beverage.

What About Coffee Makes It Hydrating?

Given the minor diuretic impact of coffee, it shouldn’t come as a huge surprise that, when drank in moderation, a part of the beverage can be counted against your daily fluid consumption requirements. After all, water is used in the production of this product!

Coffee vs. Tea: Which Is More Hydrating?

When consumed in moderation, coffee and tea may both be used to help you meet your hydration goals, at least in part. Coffee contains more caffeine per cup than all other types of tea, when measured cup for caffeinated cup. For this reason, tea is considered to be somewhat more hydrating than coffee, especially when choosing a tea that is naturally caffeine-free or has just a little amount of caffeine, such as green tea. Decaffeinated coffee and tea are both virtually totally free of caffeine, and as a result, they would both be equally hydrating.

Types of Coffee: How Hydrating Are They?

Because there are so many various varieties of coffee to pick from, the amount of hydration you receive from your cup will vary depending on your own choice. The quantity of hydration you will receive is determined by two key factors: the amount of caffeine in the beverage and the volume of the beverage. A typical 8-ounce cup of ordinary brewed coffee has around 96 milligrams of caffeine, whereas an equivalent-sized cup of decaffeinated brewed coffee contains only 2 milligrams of caffeine, according to the Mayo Clinic.

Caffeinated instant coffee sits midway in the middle, at 62 mg of caffeine per 8-oz cup, on the caffeine scale.

An espresso shot contains around 64 mg of caffeine, which is almost as diuretic as a whole 8 oz of caffeinated coffee. However, because it is packed into only 1 oz of fluid and has no hydrating properties, an espresso shot has little to no hydrating properties at all.

Health Benefits of Coffee Beyond Hydration

According to the Mayo Clinic, consuming up to 400 mg of caffeine per day is considered safe. This would be the equivalent of around four 8-ounce cups each day, or 32 ounces in total. When eaten in moderation, coffee may really provide a number of health advantages in addition to the energy boost that so many people crave (at or under that 400-mg-per-day mark). Furthermore, the antioxidants found in both caffeinated and decaf variants can have anti-inflammatory properties and, when drunk in moderation, may help reduce the risk of illnesses such as type 2 diabetes and some forms of cancer, according to Harvard University.

Tips for Enjoying Coffee to Maximize the Perks

Do you want to know if there is a “best practice” for getting the most out of your coffee? While there isn’t a single best method to drink coffee, even modest adjustments to your existing practice might make a significant impact in your nutrient intake. A natural low-calorie and reasonably nutritious beverage may become a calorie-dense chemical bomb by simply adding ingredients such as sugar, sweeteners, or industrial creamers to it. In order to reap the most benefits from your cup of coffee, drink it black or with a modest quantity (ideally measured) of milk or cream.

This will enhance the flavor of the dish without adding the calories and sugar that flavored syrups do.

Should You Drink Coffee to Stay Hydrated?

Whatever your particular health objectives are, water will always be your best choice when it comes to being well hydrated. For those who drink a few cups of coffee each day, such as the majority of individuals in the United States, you may continue doing so — and begin calculating a percentage of the calories you consume toward your personal fluid target as a result.

How Much Caffeine is Too Much?

The use of coffee appears to be beneficial whether one is struggling to get out of bed on a rainy morning or attempting to withstand the world’s longest staff meeting. Is your dependency on caffeine, on the other hand, beneficial or harmful? Cleveland Clinic is a not-for-profit academic medical facility located in Cleveland, Ohio.

According to Czerwony, “caffeine is a stimulant that has a variety of effects on the human body.” “Can you tell me how much caffeine is too much?” To make a decision, you must consider the risks and advantages.”

How much caffeine should you have in a day?

That is dependent on your personality.

Caffeine is not suitable for all people. Caffeine should be avoided by several persons, including:

  • Those with heart disease or high blood pressure
  • Children
  • Those using anti-anxiety drugs
  • Women who are pregnant or breast-feeding
  • People with anxiety disorders

Caffeine is safe to use in moderation if you are otherwise healthy. Listed below are the parameters.

  • Caffeine should not be consumed in excess of 400 milligrams (mg) per day by otherwise healthy persons. That’s the equivalent to around four 8-ounce cups of brewed coffee or ten 12-ounce cans of cola. A daily caffeine consumption of less than 100 mg (equivalent to one 8-ounce cup of coffee or about two cans of cola) is recommended for teenagers.

Side effects of too much caffeine

Caffeine, on the other hand, is not without its benefits. Caffeine, as a stimulant, can make you feel more energized, increase your physical and mental performance, and even help you lose weight. However, more does not necessarily equate to better. Overconsumption of caffeine can result in a variety of unpleasant and even dangerous adverse effects, including:


If you’ve had a bad night’s sleep, you might grab for a cup of coffee to assist you get through the day the following day. The problem is that consuming too much of it might cause insomnia the next night. “It turns into a vicious loop,” Czerwony explains. Prevent drinking caffeinated beverages in the afternoon and evening to avoid disturbing your precious sleep.


“Caffeine stimulates the activity of your central nervous system,” adds Czerwony. “This can lead to feelings of anxiety, jitteriness, and irritability.” Caffeine use should be limited to help keep those negative effects under control. However, if you have been diagnosed with an anxiety condition, you should avoid coffee at all costs.

Heart palpitations and racing heart

A large number of people suffer from heart palpitations and anxiety at the same time. Caffeine can exacerbate the symptoms of both conditions. Heart palpitations are characterized by the sensation that the heart is speeding, fluttering, or skipping a beat. They can be frightening, even if they aren’t necessarily harmful, which is another excellent reason to forego that second cappuccino.


Caffeine has diuretic properties, which means it causes you to pee. And if you’re drinking coffee all day, you’re probably not getting enough water in your system. If you want to prevent being dehydrated, drink lots of water along with any caffeinated beverages you may be drinking.

High blood pressure

According to some study, caffeine can induce minor increases in heart rate and blood pressure in certain people. People who already have high blood pressure or other cardiac issues may experience complications as a result of this rise.

Heartburn and stomach upset

“Caffeine has been shown to increase the production of stomach acid,” Czerwony explains. As a consequence, heartburn sensations become unbearable. Coffee’s acidity can contribute to the problem, but it is not the only source of acidity. Caffeine in soda and other sources can also promote acid reflux. “An excessive amount of caffeine might induce gastrointestinal difficulties,” she continues.

Caffeine toxicity

Caffeine at really high concentrations can be hazardous. That’s one of the reasons Czerwony advises against using energy drinks and energy shots, which can contain far more caffeine than a cup of strong coffee. Caffeine can be found in certain weight reduction products, and an overdose can result in significant — and perhaps fatal — cardiac rhythm disorders.

Caffeine withdrawal

Having too caffeine in your system might be deadly. The fact that energy drinks and shots might contain significantly more caffeine than an ordinary cup of coffee is one reason why Czerwony advises against drinking them.

Overdosing on caffeine, which is found in certain weight reduction products, can result in significant — and perhaps fatal — cardiac rhythm issues.

How to cut back on caffeine without withdrawal headaches

Some people are more sensitive to caffeine than others, and this is due to genetics. When using less than 400 mg per day and without experiencing any negative side effects, you may not need to give up your morning latte or afternoon soda habit, according to the researchers. If you, on the other hand, desire that your cold brew habit had less sway over you, The first step is to become aware of how much caffeine you’re taking. There are several dietary and non-food sources that contain the stimulant, including:

  • Energy drinks, weight reduction supplements, over-the-counter drugs, including certain pain killers, and tobacco are all considered to be caloric sources.

Once you’ve determined where your caffeine is coming from, Czerwony recommends devising a strategy for reducing your intake. Reduce your caffeine intake gradually over several weeks to prevent experiencing a headache or other withdrawal symptoms. Czerwony advises substituting half-decaf coffee for your typical cup of joe. Alternatively, try substituting fizzy water or herbal tea with every other can of soda. With a little trial and error, you’ll be able to discover a balance that keeps you awake and invigorated while still avoiding the negative side effects.

“An excess of a good thing is still an excess of a good thing.”

  6. But what if you’re consuming more than five cups of coffee every day?
  7. No, not at all.
  8. The incidence of heart attack and heart disease has been found to be somewhat greater in earlier research, particularly among persons who consume more than six cups of coffee per day.

Robert Eckel, MD, a professor of medicine at the University of Colorado and a former president of the American Heart Association, researchers believe that drinking alcohol has beneficial effects on the body because it releases “a series of molecules that may reduce insulin resistance and inflammation.” (Learn how to tell if inflammation is affecting your health by reading this article.) Coffee also contains antioxidant effects, which is an added bonus.

When study first showed that coffee could be the most important source of antioxidants in the American diet, it was published in 2005.

Eckel is also keen to note out that all of the good benefits of coffee were only observed in non-smokers, which is consistent with previous research.

Is there a moral to this story?

Eckel believes that the health advantages shown in theCirculationstudy aren’t nearly strong enough to justify increasing your coffee intake or beginning a coffee habit.
