Coffee

Coffee can make us feel more alert, boost our metabolism, make our heart race, affect our digestive system and more. And though most of us are aware of the brief caffeine high that coffee offers, most of us don’t really know how coffee truly affects our body.

To learn more about the effects of coffee, both immediate and long-term, keep reading.

Coffee as a Stimulant

Coffee and caffeine are stimulants. You know that when you drink coffee you feel more awake, but you also know that too much coffee can give you the jitters or cause irritability.

Because coffee is a stimulant, it can also wreak havoc on your sleeping schedule. If you have trouble falling asleep at night, try cutting back on your coffee consumption or opting for water or decaf after noon.

Coffee on the Digestive System

Coffee actually has fairly high acid levels, particularly with beans like Kenyan or Ethiopian roasts. This is why when you drink too much coffee on an empty stomach, you’ll often experience “coffee tummy” or “coffee gut,” a basic discomfort in your digestive system.

The caffeine and acid in coffee can also be problematic for people suffering from ulcers. So, if you’re having trouble with coffee, try switching to water, herbal teas or drinking milk with your coffee.

Coffee and Antioxidants

Coffee is actually the primary source of antioxidants for most North Americans. Antioxidants are, essentially, any compounds that fight or neutralize free radicals, which cause cells to break down and are cancer causing agents.

Studies have shown that coffee consumption can reduce the risk of developing liver cancer, throat cancer, Type 2 Diabetes, Alzheimer’s Disease, Parkinson’s disease and cancer of the esophagus.

Coffee and Physical and Mental Performance

Coffee isn’t just a study aid because it helps you stay awake – regular coffee consumption can actually improve your cognitive ability. A recent study showed that participants who regularly consumed at least one to two coffees a day scored higher on short term memory recall, spatial ability, logic tests and general IQ testing.

Coffee and Weight Loss

Coffee is a stimulant, meaning with every sip of caffeine, your metabolism will get a kick start. You’ll also have more energy. For example, if you read the ingredients list for most pill-form dietary or weight-loss aids, you’ll see one of the main ingredients is often caffeine.

Coffee and Your Teeth

While coffee can actually reduce cavities thanks to its acidity, it can also cause major teeth staining. To keep your teeth white, follow a cup of coffee with a bottle of water and brush your teeth at least two to three times a day.

Coffee has been a popular start to many people’s day for many years. Though coffee is often looked on negatively due to the caffeine in it there are actually many health benefits to coffee.

Antioxidants are contained in coffee and many people are unaware. Coffee contains these health boosting antioxidants no matter if you are drinking straight coffee or a varied drink such as a cappuccino. Coffee is actually good for you like many things as long as you drink it in moderation.

Often people may avoid drinking coffee due to its effects on the body from the amount of caffeine contained. Caffeine however is not the only ingredient and unfortunately many overshadow the other ingredients in coffee, which are beneficial. The antioxidants in coffee have been proven to boost your immune system and help to ward off illness. Antioxidants are also proven to decrease the likelihood of developing heart disease.

Antioxidants also reduce the risks of developing liver cirrhosis leading to liver cancer. This is good news to many especially when so many medicines increase the risk of liver problems. Drinking coffee is not a replacement for regular checkups and screening from your family doctor. Drinking coffee is however a helpful tool to reduce the likelihood of developing these issues.

Coffee has also been proven to increase alertness and concentration in adults. This is especially good news since many people drink coffee specifically for the reason of staying alert or concentration. It is a common sight to see many people starting their day with a hot cup of coffee.

Although there is many benefits to drinking coffee drinking too much coffee has been related to insomnia, and ulcers. This is mainly due to large excess amounts of coffee. It is recommended that you consume between two and three cups of coffee per day in order to reap the benefits of coffee without causing adverse side effects.

A few other diseases that coffee has been shown to reduce are colon cancer, Alzheimer’s, Type II diabetes and Parkinson’s disease. This is been scientifically proven in various government based studies along with many private health studies.

Due to all the benefits of drinking coffee it is no wonder that coffee has increased greatly in sales in recent years. People are drinking coffee more and more due to the availability and the benefits. As more people realize some of the natural health benefits of coffee it will surely increase in sales once again.

The additional medicinal benefits of coffee are yet to be found. Other countries have recognized the use of coffee as a medicine in the past; with sufficient research it is possible that coffee may prove to be beneficial as an additional source of help for some diseases.

For years, the news about coffee vacillated between positive and negative. At the same time, study after study extolled the health virtues of tea. But a flurry of new research suggests that coffee offers nearly as many health perks while protecting against a number of diseases.

All this is not to suggest you should start gulping endless cups of java if you’re not already a coffee lover. After all, excessive coffee intake may have a downside for some people. But if you like your daily “cuppa joe,” you can take some pleasure in knowing your coffee habit has finally been vindicated.

Antioxidants and More

A few years back, headlines trumpeted the news that coffee was the number one source of antioxidants in the American diet. It earned that claim not because it’s richer in antioxidants than fruits or vegetables, but because we drink so much of the stuff.

One of the prime antioxidants in coffee is methylpyridinium, which may help protect against colon cancer. This may explain the findings from a recent study that found women who drank three or more cups of coffee a day had half the risk of colon cancer as that of nondrinkers.

Another coffee antioxidant, chlorogenic acid, has been shown to inhibit liver cancer. In one study, for every two cups of coffee the participants drank, there was a 43 percent reduced risk of liver cancer. This same substance slows the intestines’ absorption of glucose and might help explain coffee’s protective effect against type 2 diabetes

Here’s something else you probably didn’t know: Coffee is the main dietary source of the trace element boron. Biologist Curtiss Hunt at the USDA Human Nutrition Research Center found that an eight ounce cup of instant coffee contains about 57 mcg. of boron. An essential nutrient for plants, one study found that dietary boron reduced the amount of insulin in the blood required to maintain proper glucose levels. Plus it’s one of the minerals necessary for strong bones.

Coffee is also a surprising source of more familiar minerals and nutrients, including chromium, magnesium and niacin. What’s more, a cup of coffee contains about one-third as much potassium as found in a small banana.

Coffee and Heart Health

Additional antioxidant compounds in coffee – caffeic, p-coumaric, and ferulic acids – may curb cardiovascular disease by protecting low-density lipoproteins (LDLs, the “bad” cholesterol) from oxidation, fending off inflammation and improving blood vessel function.

In 2006, Norwegian researchers found that older women drinking one to three cups of coffee daily were 24 percent less likely to die of cardiovascular disease than non-drinkers. Another study in 2007 found that people age 65 and over who consume four or more servings of caffeine daily had a lower risk of death from heart disease.

But curb your enthusiasm. Because the caffeine in coffee has a short-term elevating effect on blood pressure, people who drink one cup after another may keep their blood pressure high for periods long enough to risk heart trouble.

Coffee’s long-term effect on blood pressure has long been debated, and should be weighed against any possible benefits. A 2007 Finnish study of 24,710 healthy men and women, ages 25 to 64, found that over an average 13.2-year follow-up period, those drinking two to three cups of coffee daily were 29 percent more likely to start drug treatment for high blood pressure. The lesson here? Moderation is key when it comes to coffee, if you suffer from hypertension.

Brain Benefits

Anybody who’s experienced coffee’s morning wake-up call to the brain knows that it can temporarily help sharpen thinking. But coffee may also boost brain function in more lasting ways. A European study of 676 healthy men found that those consuming three cups of coffee daily suffered significantly less cognitive decline over 10 years than non-drinkers. And in 2007, a French study concluded that older women who drank at least three cups of coffee daily were 18 percent less likely to develop problems with verbal recall and 33 percent less prone to memory problems. And new evidence shows that middle-aged coffee drinkers slash their risk of developing dementia and Alzheimer’s disease later in life compared with those drinking no coffee or only a little. In fact, those who drank three to five cups a day cut their risk by an impressive 65 percent!

Other research shows that coffee may defend against Parkinson’s disease. A notable Finnish study found that drinking 10 cups of coffee a day slashed the risk of developing Parkinson’s by as much as 84 percent. Researchers suggested that the caffeine in coffee might stimulate dopamine, the brain chemical lacking in the disease.

From Gallstones to Gout

Coffee also seems to protect against both gallstones and kidney stones. In two large studies, people who drank two to three cups a day of caffeinated coffee were less likely to develop gallstones than nondrinkers. Decaf coffee didn’t protect against gallstones, but it did keep kidney stones at bay, perhaps simply by boosting total liquids.

And then there’s gout, a painful inflammatory condition that first attacks the big toe and then spreads to other joints. In the Health Professionals Follow-Up Study, Harvard researchers found that coffee consumption was linked to a lower blood level of uric acid – the substance linked to this type of arthritic disease. People who drank six or more cups a day were 40 percent less likely to develop gout. Decaf was also linked to a modest reduction in gout, suggesting that something other than caffeine could be credited.

One Last Thing …

Despite coffee’s growing list of benefits, the caffeinated version still may not be ideal for some people. If you’re concerned that coffee is keeping you up at night, try decaf or drink it earlier in the day. However, if you suffer from gastroesophageal reflux (GERD), be aware that decaf coffee has been shown to aggravate reflux as much as the caffeinated kind.

Caffeine is also often mentioned as a trigger for migraines, so sufferers should moderate their intake. Less clear is whether caffeine can aggravate arrhythmias or raise the risk of breast cancer in women with benign breast disease. The latest findings from Harvard’s Women’s Health Study suggest an increased risk for women who drink four or more cups of coffee daily. However, in the Iowa Women’s Health Study, no link was found.

While the jury is still out on these few potential problems, the news is generally good for people who enjoy coffee. The news is so positive, in fact, that coffee may be the new milk with the ability to claim that it “does a body good!”

Research Brief …

It’s common knowledge that most people tend to gain weight and lose bone as they age – neither of which is particularly healthy. But here’s the problem: If you try to lose unwanted weight, it only promotes more bone loss – increasing the risk of fractures and the dangerous complications that accompany them. The dilemma then is how to lose those extra pounds without doing damage to your bones. A study designed to answer that exact question provides some answers.

The research, from the University of Illinois, Urbana-Champaign and Pennsylvania State University, studied 130 men and women, aged 30 to 65. The people in the one-year study ate one of two low-calorie diets: A reduced-calorie diet that provided either the currently recommended intake of 0.36 grams of protein per pound of body weight, plus two servings of low-fat dairy a day, or 0.64 grams of protein per pound of body weight with three daily servings of low-fat dairy.

The researchers found that the weight-loss diet with nearly twice the recommended amount of protein and three servings a day of low-fat dairy not only improved calcium intake, but was much more effective at preserving bone mass during weight loss -  especially when compared to the lower protein (and higher carbohydrate) weight-loss diet. These findings add to the growing amount of evidence that high-protein diets do not leach calcium from bones, as long as calcium intake is adequate. So, when you cut back on calories, be sure to get plenty of high-quality protein, including three servings of low-fat dairy a day, to protect your bones while you’re paring pounds.

The healthcare community has done its fair share of investigating the effects of drinking coffee, and a subsequent array of health warnings and encouragements have been issued regarding its regular consumption.

Since the liver processes all that we ingest, people living with liver disease, including hepatitis, must be extra vigilant in watching everything entering their digestive system. Coffee is turning heads as a liver cancer and cirrhosis preventative. It has also been noted as a factor in reducing insulin resistance, a prominent liver disease risk factor. The keys to accentuate coffee’s benefits while avoiding any harm are to stay within moderation, be aware of conditions contraindicating its consumption, and be careful of what you add to your brew.

“Overall, the research shows that coffee is far more healthful than it is harmful,” says Tomas DePaulis, PhD, research scientist at Vanderbilt University’s Institute for Coffee Studies, which conducts its own medical research and tracks coffee studies from around the world. “For most people, very little bad comes from drinking it, but a lot of good.”

Benefits of Coffee

The latest research confirms that moderate coffee consumption harbors several benefits, including:

· Reduces the risk of alcoholic cirrhosis

· Decreases risk of type 2 diabetes

· Reduces risk of developing gallstones

· Discourages the development of colon and liver cancer

· Improves cognitive function

· Reduces headache/migraine severity

· Reduces the risk of Parkinson’s disease

· Improves endurance performance in long-duration physical activities

· Reduces the risk of liver damage in people at high risk for liver disease

Liver Benefits

In a Japanese study, researchers looked at the association between coffee consumption and liver cancer among the middle-aged and elderly. Those who drank coffee daily, or close to it, had about half the risk of hepatocellular carcinoma (HCC), a type of liver cancer, than people who never drank coffee. Among daily coffee drinkers specifically, the liver cancer rate was over 200 cases per 100,000 people over 10 years. Among those who never drank coffee the rate rose to nearly 550 cases per 100,000 people. The more coffee consumed, the lower the HCC risk.

Based on data collected from more than 125,000 people, researchers from the Kaiser Permanente Medical Care Program in California recently reported a 22 percent daily reduction of liver cirrhosis risk from alcohol with each cup of coffee consumed. Hepatitis c and other liver disease can also cause cirrhosis. Study co-author, Dr. Arthur Klatsky reports that the study found coffee did not protect the liver against those other causes of scarring.

Several studies have demonstrated that drinking coffee lowers the liver enzyme GGT, especially among heavy alcohol drinkers. Although GGT is a relevant indicator of cirrhosis risk, the liver enzyme ALT is a more specific marker of liver injury. Several population-based surveys from Italy and Japan have found a similar inverse relationship between drinking coffee and ALT levels.

Diabetes Benefits

Type 2 diabetes and one of its precursors, insulin resistance, have been making headlines in various health reports as a leading cause of fatty liver disease. (Read the posted article, How to Prevent a Fatty Liver.) After analyzing data on 126,000 people for as long as 18 years, Harvard researchers calculated that compared to those who do not partake in America’s favorite morning drink, people who consume one to three cups of caffeinated coffee daily can reduce diabetes risk by up to 10%. Having six cups or more each day slashed men’s diabetes risk by 54% and women’s by 30% over java abstainers.

Coffee is loaded with antioxidants, including a group of compounds called quinines that when administered to lab rats, increased insulin sensitivity. This increased sensitivity improves the body’s response to insulin. Coffee also has large amounts of magnesium and the antioxidants, chlorogenic acid and tocopherols. Each has been shown to improve insulin sensitivity and glucose metabolism, reducing the risk and severity of diabetes.

Possible Harm

As reported in the Harvard Women’s Health Watch, coffee is not completely devoid of risks. Caffeine, coffee’s main ingredient, is a mildly addictive stimulant with cardiovascular effects such as increased heart rate, increased blood pressure and occasional irregular heartbeat. Studies have been largely inconclusive regarding coffee and its effect on women’s health issues such as breast health, gynecological cancers and osteoporosis. Coffee has also been reported to aggravate previously existing gastrointestinal ulcers.

Researchers are quick to point out that caffeine is a drug, and can be abused if used in place of a good night’s rest or a healthy diet. We each have our own thresholds for caffeine. Most people can tolerate two cups of coffee each day without a problem. But any more than that may cause nervousness, rapid heartbeat, palpitations, sleeplessness and irritability. It can even lead to health problems such as osteoporosis or high blood pressure. Additionally, skipping your usual morning cup of joe can lead to a caffeine withdrawal headache.

Brew Additives

The greater risk of coffee consumption lies with the ingredients typically added to java. Creating a “light and sweet” drink carries an entirely separate set of hazards. Whipped cream, flavored syrups, half-and-half, sugar, sucralose and aspartame can contribute to diabetes, obesity, fatty liver disease and toxic liver reactions. Below are the statistics for a few common coffee additives:

· 2 tablespoons of flavored liquid nondairy creamer = 80 calories and 4 g fat.

· 1 tablespoon of plain liquid nondairy creamer = 25 calories, 2 g fat.

· 1 tablespoon half-and-half = 20 calories, 2 g fat.

· 1 tablespoon cream = 50 calories, 6 g fat.

· 1 tablespoon whipped cream = 90 calories, 9 g fat.

· A drizzle of Starbucks caramel syrup = 25 calories.

· 2 tablespoons flavored syrup = 80 calories, no fat.

· 2 tablespoons malt = 90 calories, 2 g fat.

· 1 tablespoon mocha syrup = 25 calories, .5 g fat.

· 1 teaspoon sugar = 15 calories.

If you prefer your coffee light and sweet, choose your additives wisely to support the healthful benefits offered by your beverage.

Putting it all Together

Individuals with pre-existing liver disease, or who are at high risk of its development, may want to think twice before sacrificing the enjoyment of a coffee ritual. While the proof of coffee reducing the risk of cirrhosis is limited to alcohol-related cirrhosis, its benefits transcend this one condition. In its entirety, this evidence supports coffee’s role in liver health. When selecting your beverage of choice, consider coffee’s ability to reduce insulin resistance, improve liver enzyme levels and prevent against liver cancer. As long as you do not harbor another risk factor to prohibit java consumption, proceed moderately and are conscious of the additives you chose, feel good about lifting your favorite cup in support of your liver’s health.
