The antioxidants in coffee have been linked to health protection. Chlorogenic acid, a polyphenol abundant in coffee, has been shown to reduce inflammation.
It may also play a key role in protection against chronic diseases, including obesity. And just in case you're wondering about the coffee fruit, it can be turned into compost or dried and brewed as tea. It's also being used in products like energy drinks since the fruit contains caffeine.
Type 2 diabetes is the most common type of diabetes, a condition resulting in high levels of blood glucose blood sugar. If untreated, diabetes can cause several health complications. The risk of type 2 diabetes has been shown to go down when coffee consumption goes up.
Possible reasons for the link include coffee's antioxidative and anti-inflammatory effects, ability to boost calorie burning, and impact on the content and diversity of health-protective gut microbes.
There may also be some good news for people with a history of developing diabetes during pregnancy, a condition called gestational diabetes. If this is you, you have a higher risk of developing type 2 diabetes later in life. But drinking caffeinated coffee may help lower that risk.
Coffee consumption may protect against certain cancers, including breast, colorectal, endometrial, and prostate cancers, heart disease, and Parkinson's disease. In terms of brain health, caffeinated coffee ups alertness and may also improve memory for up to 24 hours after consumption.
Several studies have shown that in moderation, caffeine enhances athletic performance. The effects include improved circulation, increases in muscular strength, endurance, and power, plus reduced pain. One study found that consuming coffee plus milk resulted in greater muscle glycogen recovery.
Glycogen is the stored form of glucose and the body's primary energy source. Adding coffee to a beverage with adequate amounts of carbohydrates increased muscle glycogen resynthesis during the four-hour recovery after exhaustive cycling exercise.
Dementia is a general term that describes when brain function declines. In its early stages, dementia may be difficult to recognize. But it can reach the point where it interferes with a person's ability to perform daily activities.
One study found that drinking coffee may protect against Alzheimer's disease, a condition where dementia symptoms progressively worsen. Coffee may have this protective effect because it seems to slow the process responsible for mental decline. Another study found that drinking coffee, with or without tea, was associated with a lower risk of not only dementia but also stroke.
And even after a stroke, coffee again with or without tea was still linked to a lower risk of dementia. Decaf offers health benefits, such as antioxidants, disease protection including against type 2 diabetesand even increased alertness.
So if you enjoy coffee but caffeine doesn't agree with you, you can still reap many of coffee's rewards in decaffeinated form. While coffee offers some benefits, it may have some downsides too.
As with so many other things, caffeine is best consumed in moderation. Here are the potential side effects of too much caffeine. Caffeine has long been criticized for contributing to dehydration due to its diuretic effectwhich triggers fluid loss. However, research indicates that after about four days of consistent caffeine intake, your body adjusts, which negates the dehydrating effect.
The trick is you have to be consistent. In other words, if you sometimes have one cup of coffee in the morning, sometimes three, or if you occasionally reach for it in the afternoon, you may feel the diuretic side effects, such as headache and low energy.
People who are genetically slow metabolizers of caffeine have an increased risk of heart attack, high blood pressure, and prediabetes after increasing caffeinated coffee consumption, whereas fast metabolizers do not carry these risks. For some people, caffeine can also trigger digestive irritation, including heartburn, as well as an upset stomach, anxiety, rapid heartbeat, and rebound fatigue.
Still, coffee consumption does more good than harm. Coffee consumption can also affect pregnancy. Drinking coffee during pregnancy has been linked to low birth weight, pre-term birth, and pregnancy loss.
Enjoy your coffee, and keep in mind these coffee consumption best practices:. If you love coffee, you can sip happily, enjoying its many benefits. Coffee offers antioxidants, a workout boost, and benefits for some chronic diseases, among other things. As with many things nutrition-related, the best advice is to listen to your body.
Try decaf if you suspect that caffeine is triggering some unwanted effects or limiting your performance. And don't forget good old H2O, which should always remain your primary and most consumed beverage.

Caffeine is a stimulant affecting the central nervous system that can cause different reactions in people. In sensitive individuals, it can irritate the stomach, increase anxiety or a jittery feeling, and disrupt sleep. Although many people appreciate the temporary energy boost after drinking an extra cup of coffee, high amounts of caffeine can cause unwanted heart palpitations in some. Unfiltered coffee, such as French press and Turkish coffees, contains diterpenes, substances that can raise bad LDL cholesterol and triglycerides. Espresso coffee contains moderate amounts of diterpenes. Filtered coffee drip-brewed coffee and instant coffee contain almost no diterpenes as the filtering and processing of these coffee types removes the diterpenes. Despite these factors, evidence suggests that drinking coffee regularly may lower the risk of heart disease and stroke :. Naturally occurring polyphenols in both caffeinated and decaffeinated coffee can act as antioxidants to reduce damaging oxidative stress and inflammation of cells. It may have neurological benefits in some people and act as an antidepressant. However in a few cases of sensitive individuals, higher amounts of caffeine may increase anxiety, restlessness, and insomnia. Suddenly stopping caffeine intake can cause headache, fatigue, anxiety, and low mood for a few days and may persist for up to a week. There are various proposed actions of caffeine or components in coffee that may prevent the formation of gallstones. The most common type of gallstone is made of cholesterol. Coffee may prevent cholesterol from forming into crystals in the gallbladder. It may stimulate contractions in the gallbladder and increase the flow of bile so that cholesterol does not collect. A study of 46, men tracked the development of gallstones and their coffee consumption for 10 years. After adjusting for other factors known to cause gallstones, the study concluded that men who consistently drank coffee were significantly less likely to develop gallstones compared to men who did not. The bottom line: A large body of evidence suggests that consumption of caffeinated coffee does not increase the risk of cardiovascular diseases and cancers. In fact, consumption of 3 to 5 standard cups of coffee daily has been consistently associated with a reduced risk of several chronic diseases. Specifically, those who have difficulty controlling their blood pressure may want to moderate their coffee intake. Pregnant women are also advised to aim for less than mg of caffeine daily, the amount in 2 cups of coffee, because caffeine passes through the placenta into the fetus and has been associated with pregnancy loss and low birth weight. Decaffeinated coffee is a good option if one is sensitive to caffeine, and according to the research summarized above, it offers similar health benefits as caffeinated coffee. The extra calories, sugar, and saturated fat in a coffee house beverage loaded with whipped cream and flavored syrup might offset any health benefits found in a basic black coffee. Coffee beans are the seeds of a fruit called a coffee cherry. Coffee cherries grow on coffee trees from a genus of plants called Coffea. There are a wide variety of species of coffee plants, ranging from shrubs to trees. Decaffeinated coffee. This is an option for those who experience unpleasant side effects from caffeine. The two most common methods used to remove caffeine from coffee is to apply chemical solvents methylene chloride or ethyl acetate or carbon dioxide gas. Both are applied to steamed or soaked beans, which are then allowed to dry. According to U. Both methods may cause some loss of flavor as other naturally occurring chemicals in coffee beans that impart their unique flavor and scent may be destroyed during processing. However, adding sugar, cream, and milk can quickly bump up the calorie counts. A tablespoon of cream contains 52 calories, and a tablespoon of whole milk contains 9 calories. However, the real caloric danger occurs in specialty mochas, lattes, or blended ice coffee drinks. These drinks are often super-sized and can contain anywhere from calories, as well as an extremely large amount of sugar.

Type 2 Diabetes Although ingestion of caffeine can increase blood sugar in the short-term, long-term studies have shown that habitual coffee drinkers have a lower risk of developing type 2 diabetes compared with non-drinkers. In a meta-analysis of 45, people with type 2 diabetes followed for up to 20 years, an association was found with increasing cups of coffee and a lower risk of developing diabetes. Caffeinated coffee showed a slightly greater benefit than decaffeinated coffee. Heart health Caffeine is a stimulant affecting the central nervous system that can cause different reactions in people. The authors found no such association with other caffeinated drinks such as tea and soda. These coffee-specific results suggest that components in coffee other than caffeine may be protective. Heavier coffee intake of 6 or more cups daily was neither associated with a higher nor a lower risk of cardiovascular disease. Depression Naturally occurring polyphenols in both caffeinated and decaffeinated coffee can act as antioxidants to reduce damaging oxidative stress and inflammation of cells. to 2 cups of coffee. found a decreasing risk of suicide with increasing coffee consumption. There was no association between decaffeinated coffee and suicide risk, suggesting that caffeine was the key factor, rather than plant compounds in coffee. There is consistent evidence from epidemiologic studies that higher consumption of caffeine is associated with lower risk of developing PD. The caffeine in coffee has been found in animal and cell studies to protect cells in the brain that produce dopamine. In that time, after adjusting for known risks of PD, those who drank at least 10 cups of coffee a day had a significantly lower risk of developing the disease than non-drinkers. Women showed the lowest risk when drinking moderate intakes of cups coffee daily. The authors stated the need for larger studies with longer follow-up periods. Gallstones There are various proposed actions of caffeine or components in coffee that may prevent the formation of gallstones. Mortality In a large cohort of more than , participants followed for up to 30 years, an association was found between drinking moderate amounts of coffee and lower risk of early death. Both caffeinated and decaffeinated coffee provided benefits. The authors suggested that bioactive compounds in coffee may be responsible for interfering with disease development by reducing inflammation and insulin resistance. The protective effect was present regardless of a genetic predisposition to either faster or slower caffeine metabolism. Instant and decaffeinated coffee showed a similar health benefit.

| Latest news | Drinking six or more caffeinated beverages in 24 hours has been associated with an almost four-fold increase in the risk of recurrent gout attacks. A study that looked at 1, women found that those with an intake of mg of caffeine a day, equivalent to about three cups of coffee or more, had a percent higher chance of bladder problems. Consuming caffeine 3 and even 6 hours before bedtime can significantly disrupt sleep. Up to 6 hours before bedtime, caffeine can reduce objectively measured total sleep time by more than 1 hour. A population-based study found that dietary and medicinal caffeine consumption may be a modest risk factor for triggering chronic daily headache , regardless of headache type. A study published in the journal Menopause found that women who consumed caffeine during menopause were more likely to have hot flashes and night sweats. Consuming over mg of caffeine a day can lead to:. Caffeine increases the release of acid in the stomach, sometimes leading to an upset stomach or heartburn. Caffeine can interfere with the sleep cycle. Sleep loss is cumulative, and even small nightly decreases can add up and disturb daytime alertness and performance. These include some:. In , the American Psychiatric Association APA added caffeine withdrawal to the list of recognized conditions in the Diagnostic and Statistical Manual of Mental Disorders DSM-V. However, not all caffeine consumers have withdrawal symptoms if they stop consuming caffeine. People who suddenly stop drinking coffee may experience symptoms about 12 to 24 hours after quitting. These peak after 20 to 48 hours before disappearing. Gradually reducing caffeine intake over a period of days does not trigger these symptoms. Unlike other drugs, caffeine has not been shown to activate the pathways in the brain that are related to addiction. Caffeine has been associated with increased urinary volume and frequency, causing the body to lose water and electrolytes such as potassium and sodium. However, researchers have not found a significant difference in fluid loss between people who drink or do not drink coffee. Additional water loss may occur if a person consumes more than mg a day, but the fluid consumed with the drink is likely to make up for any loss. Caffeine may affect the way the body absorbs calcium, and this has raised concerns that drinking coffee can lead to osteoporosis. Women with a good intake of calcium through their diet are unlikely to be at risk of osteoporosis as a result of drinking coffee. However, caffeine does not sober a person up or make them fit to drive. It may make them more alert, but it does not reverse the poor judgment and other effects associated with alcohol. In fact, it could be more dangerous because, without the drowsiness, a person is more likely to believe they are sober, which could lead to hazardous activities such as driving home or consuming more alcohol. There is some controversy around energy drinks. They have been banned from a number of student campuses, because of reports of health problems and even fatalities. While one ounce Americano coffee can contain mg of caffeine , the caffeine content of a ounce can of energy drink until recently ranged from mg to mg. Producers of the drink that contained mg of caffeine have now lowered their caffeine content to mg. It carries a health warning that it should not be consumed by children, those with heart problems, or those who may have an intolerance to caffeine. Energy drinks contain not only caffeine but other plant-based stimulants, simple sugars or artificial sweeteners, and additives. A ounce serving of one well-known energy drink would contain around 50 g , or 1. When alcoholic beverages are mixed with energy drinks, the caffeine can mask the depressant effects of alcohol. Alcohol also decreases the metabolism of caffeine, prolonging its effects. Drinkers who consume alcohol mixed with energy drinks are three times more likely to binge drink than drinkers who do not report mixing alcohol with energy drinks. They are also twice as likely to report experiencing sexual assault, sexually assaulting someone else, riding with a driver who was under the influence of alcohol, being physically hurt or injured, and requiring medical treatment. A person is unlikely to die from consuming too much caffeine in the diet. It is estimated that it would take or so cans of caffeinated energy drink to kill an average adult male. Vomiting would most certainly occur before a person had a chance to consume a fatal overdose of caffeine from dietary sources. However, pure caffeine is a powerful stimulant, and very small amounts can lead to an accidental overdose. A single teaspoon of pure caffeine is roughly equivalent to 28 cups of coffee. Whether consumed as a food or a medicine, the blood and body tissues absorb caffeine within around 45 minutes. It reaches peak level in the blood within 1 hour and remains there for 4 to 6 hours. Adenosine promotes sleep and suppresses arousal by slowing down nerve activity. Adenosine binding also causes blood vessels in the brain to dilate, to increase oxygen intake during sleep. When awake, the levels of adenosine in the brain rise each hour, making the brain and the body less alert. As caffeine utilizes all the receptors adenosine binds to, the cells can no longer sense adenosine. As a result, instead of slowing down because of the adenosine level, cellular activity speeds up. This is why caffeine is used in pain relief medicine for headaches. If the headache is vascular, relief comes as the caffeine narrows the blood vessels. The blocking of adenosine causes excitatory neurotransmitters to increase in the brain. The pituitary gland notices this increased activity and releases hormones that tell the adrenal glands to produce epinephrine. Moderate amounts of caffeine appear not to be harmful, and a moderate intake of caffeine may bring health benefits. In addition, the current trend for adding caffeine to foods such as gum and ice cream, items that commonly target children remains a matter of concern , and investigations are ongoing.

Caffeine and coffee benefits -
Caffeine has been shown to raise both blood sugar and insulin levels in people with the disease. A number of studies have suggested that consuming caffeine can reduce your risk of developing Parkinson's disease — and research published in in the journal of the American Academy of Neurology showed that a daily dose of caffeine equivalent to that found in two eight-ounce cups of black coffee can help to control the involuntary movements of people who already have the disease.
You'd have to drink nearly eight cups of brewed black tea to get the same amount of caffeine. In a study published in the Journal of Alzheimer's Disease , Florida researchers tested the blood levels of caffeine in older adults with mild cognitive impairments, which can be a precursor to severe dementia , including Alzheimer's disease.
When the researchers re-evaluated the subjects two to four years later, those whose blood levels contained caffeine amounts equivalent to about three cups of coffee were far less likely to have progressed to full-blown dementia than those who had consumed little or no caffeine.
Several studies published in respected journals have found that coffee drinking has beneficial effects on the liver, including reducing the risk of death from liver cirrhosis , decreasing harmful liver enzyme levels and limiting liver scarring in people who have hepatitis C.
According to a study published in in the American Heart Association journal Circulation: Heart Failure , drinking one or more daily cups of plain, caffeinated coffee was associated with a significant reduction in a person's long-term risk of heart failure.
The study looked at the original data from three well-known heart disease studies: the Framingham Heart Study, the Atherosclerosis Risk in Communities Study and the Cardiovascular Health Study.
Although there's not enough evidence to support prescribing coffee to lower your risk of heart disease risk, this recent revelation seems to strengthen previous findings that coffee is, in fact, good for heart health. In , the journal Epidemiology and Prevention published a review of studies analyzing the correlation between coffee consumption and cardiovascular disease.
Data from 36 different studies showed that people who drink three to five cups of coffee per day had a lower risk of heart disease than those who drink no coffee or more than five cups per day.
While the reason isn't clear, one possibility is that coffee helps to improve blood vessels' control over blood flow and blood pressure.
A study appearing in the Journal of the National Cancer Institute looked at the coffee-drinking habits of more than , people over 10 years. Your morning coffee could help lower your risk of death. A study in The Annals of Internal Medicine has shown that moderate consumption of unsweetened and sugar-sweetened coffee was associated with a reduced risk of mortality.
