Product Information

While Diet Coke uses aspartame as its sweetening agent, Coke Zero uses both aspartame and acesulfame potassium, also called “Ace K” or “acesulfame K.” Withdrawal can cause mild to clinically significant distress or impairment in daily functioning. The frequency at which this occurs is self-reported at 11%, but in lab tests only half of the people who report withdrawal actually experience it, casting doubt on many claims of dependence. [121] Mild physical dependence and withdrawal symptoms may occur upon abstinence, with greater than 100mg caffeine per day, although these symptoms last no longer than a day. [2] Some symptoms associated with psychological dependence may also occur during withdrawal. [6] The diagnostic criteria for caffeine withdrawal require a previous prolonged daily use of caffeine. [122] Following 24 hours of a marked reduction in consumption, a minimum of 3 of these signs or symptoms is required to meet withdrawal criteria: difficulty concentrating, depressed mood/ irritability, flu-like symptoms, headache, and fatigue. [122] Additionally, the signs and symptoms must disrupt important areas of functioning and are not associated with effects of another condition. [122] The differing perceptions in the effects of ingesting beverages made from various plants containing caffeine could be explained by the fact that these beverages also contain varying mixtures of other methylxanthine alkaloids, including the cardiac stimulants theophylline and theobromine, and polyphenols that can form insoluble complexes with caffeine. [219] Products Caffeine content in select food and drugs [220] [221] [222] [223] [224] For the general population of healthy adults, Health Canada advises a daily intake of no more than 400mg. [72] This limit was found to be safe by a 2017 systematic review on caffeine toxicology. [73] Children Pure anhydrous caffeine is a bitter-tasting, white, odorless powder with a melting point of 235–238°C. [10] [11] Caffeine is moderately soluble in water at room temperature (2g/100 mL), but very soluble in boiling water (66g/100 mL). [193] It is also moderately soluble in ethanol (1.5g/100 mL). [193] It is weakly basic (pK a of conjugate acid = ~0.6) requiring strong acid to protonate it. [194] Caffeine does not contain any stereogenic centers [195] and hence is classified as an achiral molecule. [196]

In one study, 12 young to middle-aged people with overactive bladders who consumed 2 mg of caffeine per pound (4.5 mg per kilogram) of body weight daily experienced significant increases in urinary frequency and urgency ( 44). Some textbooks state that caffeine is a mild euphoriant, [104] [105] [106] while others state that it is not a euphoriant. [107] [108] a b c Burchfield G (1997). Meredith H (ed.). "What's your poison: caffeine". Australian Broadcasting Corporation. Archived from the original on 26 July 2009 . Retrieved 15 January 2014. The amount of caffeine in food and drinks varies. For example, an espresso has more caffeine than instant coffee. Similarly, dark chocolate has more caffeine than milk chocolate. Source Caffeine can be quantified in blood, plasma, or serum to monitor therapy in neonates, confirm a diagnosis of poisoning, or facilitate a medicolegal death investigation. Plasma caffeine levels are usually in the range of 2–10mg/L in coffee drinkers, 12–36mg/L in neonates receiving treatment for apnea, and 40–400mg/L in victims of acute overdosage. Urinary caffeine concentration is frequently measured in competitive sports programs, for which a level in excess of 15mg/L is usually considered to represent abuse. [209] AnalogsUntil recently, the Seventh-day Adventist Church asked for its members to "abstain from caffeinated drinks", but has removed this from baptismal vows (while still recommending abstention as policy). [282] Some from these religions believe that one is not supposed to consume a non-medical, psychoactive substance, or believe that one is not supposed to consume a substance that is addictive. The Church of Jesus Christ of Latter-day Saints has said the following with regard to caffeinated beverages: "... the Church revelation spelling out health practices (Doctrine and Covenants 89) does not mention the use of caffeine. The Church's health guidelines prohibit alcoholic drinks, smoking or chewing of tobacco, and 'hot drinks' – taught by Church leaders to refer specifically to tea and coffee." [283]

It’s important to note that coffee and tea contain other bioactive compounds (besides caffeine) that may also be beneficial. SummaryDrinking or eating caffeine when taking other drugs can be unpredictable and increase your risk of harm. Caffeine and medicines Caffeine, like other xanthines, also acts as a phosphodiesterase inhibitor. [173] As a competitive nonselective phosphodiesterase inhibitor, [174] caffeine raises intracellular cyclic AMP, activates protein kinase A, inhibits TNF-alpha [175] [176] and leukotriene [177] synthesis, and reduces inflammation and innate immunity. [177] Caffeine also affects the cholinergic system where it is a moderate inhibitor of the enzyme acetylcholinesterase. [178] [179] Pharmacokinetics Caffeine is metabolized in the liver via a single demethylation, resulting in three primary metabolites, paraxanthine (84%), theobromine (12%), and theophylline (4%), depending on which methyl group is removed. Urinary metabolites of caffeine in humans at 48 hours post-dose [180] A 14-year study in 1,685 middle-aged adults did not find any association between diet soda intake and an increased risk of prediabetes ( 18).

The short-term effects of caffeine typically happen about 30 minutes after consumption. They can last up to 6 hours, depending on the individual. One 8-year observational study found that people who drank more than 21 artificially sweetened beverages per week almost doubled their risk of overweight and obesity, compared with people who didn’t consume these kinds of drinks ( 6). Caffeine can delay or prevent sleep and improves task performance during sleep deprivation. [54] Shift workers who use caffeine make fewer mistakes that could result from drowsiness. [55] Paraxanthine (84%): Increases lipolysis, leading to elevated glycerol and free fatty acid levels in blood plasma.

Caffeine content for coffee, tea, soda and more

Caffeine is used for both prevention [34] and treatment [35] of bronchopulmonary dysplasia in premature infants. It may improve weight gain during therapy [36] and reduce the incidence of cerebral palsy as well as reduce language and cognitive delay. [37] [38] On the other hand, subtle long-term side effects are possible. [39] Acesulfame potassium is another calorie-free sweetener that passes through the body without raising blood sugar levels. What’s more, in an 8-year study in 64,850 women, consuming artificially sweetened beverages increased the risk of diabetes by 21%, though the risk for those drinking sugar-sweetened beverages was even higher at 43% ( 17).

However, this effect doesn’t seem to occur in everyone. Indeed, even some people with heart problems may be able to tolerate large amounts of caffeine without any adverse effects.In one study, 16 people who typically consumed high, moderate or no caffeine took part in a word test after going without caffeine overnight. Only high caffeine users showed a bias for caffeine-related words and had strong caffeine cravings ( 31). Those who take a more cautious approach to ingredients in foods may want to avoid aspartame, and that’s OK. However, it’s worth noting that the Food and Drug Administration (FDA) considers aspartame safe ( 7). Theobromine (12%): Dilates blood vessels and increases urine volume. Theobromine is also the principal alkaloid in the cocoa bean ( chocolate). A review noted that those who drink the most coffee have up to a 29% lower risk of developing type 2 diabetes. Similarly, those who consume the most caffeine have up to a 30% lower risk ( 36).
