Caffeine is a stimulate drink popular in nearly every country for hundreds of years. In the British Colonial times, tea was the most popular drink in the world, and over the last 100 years, it has been replaced by coffee , perhaps because the stress of modern living needs more stimulant the the sedate days of the British Aristocracy where a cup to well prepared tea served by their servants was a sign of luxury and status.
Coffee tee, caffeinated soft drinks and energy drinks that 90 percent of us consume caffeine in some form or another each day.
Recently, more and more the health benefits and risks as been a cause of speculation research and debates. Coffee is used for its stimulant effects, boosting memory and concentrationbut are you helping yourself or harming ourselves. The answer is unclear
Caffeine is a drug and while low to moderate doses are generally safe, caffeine is addictive and users can become dependent on it and find it difficult to quit or even cut back, he says. (Caffeine dependence was even named as a new mental disorder this year.) Anyone who’s ever quit cold turkey knows it can trigger pounding headaches, mental fuzziness and fatigue for a couple of days until the body adjusts.
“Coffee is an amazingly potent collection of biologically active compounds,” Walter Willett, M.D., of the Harvard School of Public Health, told the National Institutes of Health’s newsletter.
Experts say that you should not exceed 300 mg which is about the amount in three 8-ounce cups of coffee, depending on how strong you brew it
Effects of too much caffeine:
It increases anxiety and disrupts sleep patterns, leading to a vicious cycle of restless sleep, relying on caffeine to help with daytime fatigue, followed by more insomnia
It may interact with medication including thyroid medication , psychiatric and antibiotic Cipro and the heartburn drug
It may increase your blood sugar levels, making it harder for those with diabetes manage their blood sugar , increase your blood pressure causing blood pressure elevations
Caffeine potentially leads to some spinal bone loss in postmenopausal women if they typically drink more than three cups, or 300 mg of caffeine, a day, but don’t get enough calcium in their diet.
If you have high cholesterols and you don’t want your coffee adding to the problem, you may need to use a paper filter to trap the cafestol, a compound in coffee that raises LDL cholesterol levels
Caffeine’s may increase acid in the stomach Caffeine seems to be the main culprit by relaxing the sphincter muscle that normally keeps stomach acid from bubbling up the esophagus.
Caffeine has been shown to protect against a host of problems. Some studies have found that those who drink lots of coffee seem to be four to eight times less likely to develop Parkinson’s disease, according to the NIH’s National Institute of Neurological Disorders and Stroke, and “that is more likely to be due to caffeine” than to any nutrients in coffee, says van Dam.
It may reduce the risk of Alzheimers and dementia. A caffeine habit in your 40s and 50s — three to five cups daily of the high-octane stuff, not decaf — seems to reduce by up to 70 percent the risk of Alzheimer’s and dementia in your 70s, a 2009 University of Florida study found. Other studies have found that regular caffeine consumption may help slow the rate of cognitive decline in older adults.
Coffee cuts suicide risk. A 2013 study by Harvard’s School of Public Health found that those who drank two to three cups of caffeinated coffee a day cut their suicide risk by 45 percent — possibly because caffeine’s stimulant effect helps boost people’s moods.
It lowers risk of oral cancer. Older adults who drank four or more 8-ounce cups of regular coffee daily were half as likely to die of mouth and upper throat cancer. Decaf had a weaker effect, while no protection was found with tea.
Coffee lowers the risk of stroke for older women. A 2009 U.S. study and a 2011 Swedish study both found that older women who drink more than a cup of caffeinated coffee daily have a 20 to 25 percent lower risk of stroke. A 2008 Swedish study found a similar result in older men.
The largest study to date, a joint project last year by the NIH’s National Cancer Institute and AARP that followed 400,000 men and women ages 50 to 71 for more than 10 years, found that those who regularly drank coffee — either decaf or regular — had a lower risk of overall death than did nondrinkers. In particular, the coffee drinkers were less likely to die from heart disease, respiratory disease, stroke, injuries and accidents, diabetes, and infections.
Weight loss and metabolic syndrome
Despite coffee’s association with increased blood pressure, the steamy brew appears to benefit other aspects of so-called “metabolic syndrome,” the dangerous cluster of hypertension, hyperglycemia, abnormal lipid levels, and increased body fat. Numerous studies have linked regular coffee drinking with improved glucose metabolism, insulin secretion, and a significantly reduced risk for type 2 diabetes P. Overweight patients treated with unroasted coffee beans may lose weight This may be due in part to coffee containing chlorogenic acid, a plant compound with antioxidant properties thought to reduce glucose absorption.
The liver might help break down coffee, but coffee might protect the liver (in some cases). Evidence suggests that coffee consumption slows disease progression in patients with alcoholic cirrhosis and hepatitis C and reduces the risk of developing hepatocellular carcinoma. It has been reported that coffee intake is associated with a lower risk for nonalcoholic fatty liver disease and has a protective effect
A 2010 overview of major studies on coffee consumption and cancer by the University of California, Los Angeles, found a strong protective association between coffee and endometrial (also called uterine) cancer and some protection from colon cancer; other recent studies have found that drinking coffee may protect against prostate and liver cancer.
Studies from around the world consistently show that high consumption of caffeinated or decaffeinated coffee is associated with low risk of type 2 diabetes,.
Research suggests that coffee intake may relieve dry eye syndrome by increasing tear production, reduce the risk for gout and potentially fight infection.Coffee and hot tea consumption found to be to be protective against one of the medical community’s most concerning bugs, methicillin-resistant Staphylococcus aureus (MRSA). While it remains unclear whether the beverages have systemic antimicrobial activity, study participants who reported any consumption of either were approximately half as likely to have MRSA in their nasal passages.
