क्योंकि केफीन को एक सामाजिक स्वीकृति प्राप्त है इसीलिए इसके सेहत पर पड़ने वाले नकारात्मक प्रभावों की तरफ समाज की तवज्जो नहीं मिली है। हमारी परम्परा और दैनिकी में यह चुपके से शामिल हो गई है।
बेशक कितने ही लोग इसके अवांछित प्रभावों से बे-असर बने रहते हैं लेकिन कई अन्यों को इसके दुष्परिणाम भुगतने पड़ते है। इसकी लत पड़ जाती है। बैसाखी बन जाती है कईओं की केफीन। इस पर भौतिक निर्भरता बे -हिसाब बढ़ जाती है। रोज़मर्रा के कामों पर भी इसका असर दिखने लगता है।
माहिरों के अनुसार सेहत मंद तंदरुस्त लोगों को एक दिन में ४०० मिलीग्राम से ज्यादा केफीन का किसी भी रूप में सेवन नहीं करना चाहिए इसका मतलब हुआ कॉफी के दिन भर में दो तीन प्याले।
गर्भवती महिलाओं के लिए यह सीमा २०० मिलीग्राम से कम बतलाई गई है।
बे -कली ,बे -चैनी (एंग्जायटी )या फिर अनिद्रा की गिरिफ्त में रहने वाले लोगों ,उच्च रक्त चाप ,दिल के रोगों से ग्रस्त लोगों ,मूत्र त्याग में संयम न रख पाने वाले लोगों के लिए भी इसका सेवन कमतर बतलाया गया है।
लत पड़ जाने पर यह गर्भावस्था ,,दिल की समस्याओं से घिर जाने जैसी मेडिअकल कंडीशन में भी फिर पिंड नहीं छोड़ती है। ब्लीडिंग डिस-ऑर्डर में भी लती केफीन का सेवन नहीं छोड़ पाते हैं।
यह निष्कर्ष अमरीकी यूनिवर्सिटी में मनो विज्ञान के प्रोफ़ेसर लौरा जुलियानों एवं उनके साथियों ने निकाले हैं। उन्हीं के शब्दों में :
"CUP OF WOES :Some people are unable to reduce caffeine consumption even if they have another condition that may be impacted by it .These symptoms combined are a condition called 'Caffeine Use Disorder'
The Caffeine Crutch
Overworked and sleep-deprived, more people are using caffeine as an energy crutch than ever before, experts say. That’s not all bad: In fact, 250 milligrams of caffeine per day—that’s two to three cups of joe—wakes up the brain, improves concentration, relieves stress, and may also help you live longer. But if intake is turning into addiction, you may notice side effects , including dehydration, trouble sleeping, anxiety, an upset stomach, and even problems during prenancy.
Caffeine Can Be Hidden
If you’re trying to cut back, you’ve probably already reduced the amount of coffee, tea, and sodas that you consume. But the sneaky stimulant can pop up in unexpected places. Since the U.S. Food and Drug Administration(FDA) doesn’t require manufacturers to list caffeine content on nutrition labels, it’s often hard to tell whether a product contains the stimulant, and how much.These sources of caffeine—some hidden, some just plain weird—could be giving you the jitters.
The name implies that this cup of java delivers all the taste you love without the caffeine, but don’t be fooled. In 2007, Consumer Reports tested 36 cups of decaffeinated coffee from six coffee standbys, including Starbucks and Dunkin’ Donuts. Compared to the caffeine found in a regular cup (generally around 100 milligrams), the decaf samples had less, but some packed in over 20.
Colas and other sodas like Mountain Dew are well-known caffeinated culprits, but others play less obvious roles in your daily caffeine intake. Some brands of root beer, such as Barq’s, contain caffeine. Both the regular and diet flavors have 23 milligrams per 12-ounce can, just 12 milligrams less than a can of Coke. Sunkist’s orange soda has a surprising 41 milligrams of caffeine, and A&W Cream Soda has about 25 milligrams.
Caffeine is found naturally in cocoa beans, so any chocolate has a little bit of the stimulant. Candy bars generally have less than 10 milligrams, but the darker the chocolate, the higher the caffeine content. Hershey’s Special Dark Chocolate Bar has a whopping 31 milligrams, almost as much as a can of Coke! Some chocolate is fortified with additional caffeine for an energy boost—take the limited edition Snickers Charge, which has 60 milligrams of caffeine, about the same as a cup of tea.
If there’s coffee or chocolate in your ice cream, expect the scoop to deliver a small jolt. Many popular brands have coffee flavors that contain between 30 and 45 milligrams of caffeine per half cup, which is about the same as a can of Coke. Chocolate ice cream has much less, however; a half cup of Breyer’s All Natural Chocolate ice cream has only 3 milligrams, according to a Consumer Reports analysis.
Weight loss pills
Caffeine really doesn’t do much to shrink your waistline, yet diet pill manufacturers have overloaded their pills with the stimulant. For example, taking 1,223 milligrams in a daily dose of Zantrex-3 is like having 12 cups of coffee, according to a 2005 analysis conducted by ConsumerLab.com.
A little caffeine can curb headaches, but in large quantities it can actually cause them, some research suggests. Many pain relievers incorporate caffeine to ease the pain, but if you take more than the label suggests, you could be taking more than you need. Two Excedrin Migraine tablets have 130 milligrams of caffeine, the same as a Starbucks Light Frappuccino with espresso— so stick with the two-tablets-per-24-hours label instructions.
Energy water '
Riding the coattails of the fortified water trend is a new concoction from various bottling companies: caffeinated water. Some packaging, like that of the former Fruit2O Energy, which boasted as much caffeine as a cup of coffee, displays caffeine content prominently. But others, specifically those flavored with guarana, a Brazilian plant that is a natural source of caffeine, are less obvious; for example, Propel’s limited edition Invigorating flavor has 50 milligrams of caffeine, as does VitaminWater’s Energy flavor.
Alcoholic energy drinks
The practice of mixing caffeinated beverages and alcohol – popular among college-age drinkers – also has gained traction among adolescents, according to a new study co-authored by BU School of researchers.
The study – led by BUSPH student Kalé Z. Kponee and community professor Michael Siegel, and published in the journal Addictive Behaviors – indicates that mixing caffeine and alcohol is more common among underage drinkers and starts at a much earlier age that previously thought.
The research team, which includes David H. Jernigan from the Johns
School of Public Health, found that young people who consumed energy drinks mixed with alcohol were several times more likely to binge drink, get in fights and sustain alcohol-related injuries than those who did not.
Adolescents who consumed alcohol mixed with had almost twice the average drinking days per month as those who did not mix caffeine with alcohol. They also consumed almost triple the total number of drinks per month compared to non-caffeine users.
Despite the number of claims about the benefits of coffee ,the truth is :
COFFEE ADDICTION IS HARMFUL TO YOUR HEALTH
If you’re like over half the adult population in the United States, you drink coffee every day. By the end of the year, you will have consumed over ten pounds of the stuff.
What’s disturbing is that a tremendous number of people, including you, are made to believe that coffee is good for your health. Like a drug, coffee gets you addicted to drinking it every time. You enjoy its great taste and turn to coffee to get your energy boost for the day.
In fact, drinking coffee has become so addictive that some people can’t get through the day without downing several cups in the morning, noon and night. It has even evolved into a social drink, with consumers spending generously on sugar-loaded concoctions from Starbucks and other cafes.
