Caffeine, commonly found in coffee, tea, cocoa, and some medications, acts to stimulate the body in various ways – inhibiting nucleotide phosphodiesterase enzymes, blocking adenosine receptors, and stimulating lipolysis, to name but a few actions it plays a part. Check out the Best info about Caffeine database.
Before now, no database was available in Brazil that provides the caffeine content of popular Brazilian foods and beverages consumed by its population. This study seeks to create such a table.

What is Caffeine?
Caffeine is a naturally occurring stimulant found in coffee beans, tea leaves, cocoa pods, and kola nuts. Additionally, caffeine is added to many over-the-counter and prescription medicines as a means to combat fatigue or increase pain relief effectiveness.
The FDA considers caffeine a food and drug additive. Its primary action appears to be stimulating the central nervous system for approximately six hours; additionally, it blocks specific adenosine receptors and inhibits phosphodiesterases.
Caffeine has many effects that depend on who takes it and can range from increased blood pressure, heart rate, energy or anxiety levels, interference with sleep, increased urination, and even dehydration. Many individuals can quickly build a tolerance to caffeine, needing ever-increasing amounts to feel its effects.
Up to 400 mg of caffeine per day is considered safe for healthy adults, which equates to roughly four cups of brewed coffee, ten cans of cola, or two “energy” drinks. However, caffeine’s effects vary among people; even small doses could prove hazardous during pregnancy or for those suffering from high blood pressure, heart rhythm disorders, or migraine headaches. Certain medicines or supplements may interfere with how well your body processes caffeine.
Caffeine Sources
Caffeine can be found naturally in various foods and beverages. Most people consume caffeine primarily through coffee and tea consumption. However, other sources include chocolate, non-prescription medications such as cough syrup or slimming tablets as well as energy drinks.
Coffee’s stimulant effects aside, caffeine may also interfere with sleep and increase stomach acid secretion in some people. Pregnant women, young children, or those with chronic heart conditions should avoid taking caffeine; only consume it in moderation and only as necessary.
Figures 2A and B provide an analysis of fourteen years of trends in caffeine consumption overall and by beverage source among children and adults, respectively. Both groups saw their average caffeine intake decrease between 2003-2004 and 2011-2012; this reduction can largely be attributed to reduced soda consumption among both groups – the primary source of caffeine consumption for both.
Data on caffeine consumption are collected via 24-hour dietary recall surveys conducted every year since 2011. Figures 2A and B show trends adjusted for age group, race/ethnicity, family income, and educational attainment to demonstrate trends in caffeine consumption over time. Sensitivity analyses were then performed to ascertain whether the increase was attributable to demographic shifts rather than trend changes alone.
Caffeine Content
Caffeine is a naturally occurring chemical stimulant found in coffee beans, cocoa beans, tea leaves, guarana berries, yerba mate leaves, and kola nuts, but it is also produced synthetically for use as food additives and dietary supplements. Most commonly consumed as beverages such as coffee or soda in the United States, it may also be added to medicines and herbal remedies as an ingredient.
Mitchell and colleagues collected comprehensive beverage diary data from a representative sample of U.S. populations and organized it into four main categories: coffee, carbonated soft drinks, tea, and energy drinks – an approach consistent with previous ILSI surveys since most adult caffeine consumption comes from these four beverages.
Recent survey findings indicated caffeine intake ranged from 0.4 to 509 mg per reference amount customarily consumed (RACC), with coffee having the highest average consumption among all categories, followed by carbonated soft drinks and tea; energy drinks had lower average consumption but saw a significant increase among 12- to 17-year-old age group users.
On top of its direct effects on the central nervous system, caffeine may also stimulate metabolism by increasing cell availability of free fatty acids and stimulating lipolysis (the breakdown of stored fat stores). Furthermore, caffeine may inhibit cyclic nucleotide phosphodiesterase enzymes in skeletal muscles, which increases intracellular concentrations of cAMP, stimulating neurotransmitter secretion while improving contractile force.
Caffeine Calculator
Caffeine can be an effective stimulant when consumed in moderation and can help increase performance. However, excessive caffeine consumption can lead to adverse side effects like irritability, headaches, and difficulty sleeping – the caffeine calculator makes it easy to track daily caffeine consumption so that it stays within an appropriate limit.
Adults should only consume up to 400 mg per day of caffeine, with this calculator providing an estimate based on your body weight. You can also choose the number of beverages or their caffeine contents when entering advanced mode mode.
Once you enter the caffeine content of your drinks, this app will calculate and provide an in-depth breakdown of how much caffeine was consumed throughout your day, showing average amounts in each drink and how long they remain in your system – helping prevent you from overconsumption of coffee or other caffeinated beverages.
The caffeine calculator can be downloaded onto any Android device through the Google Play store. Click ‘Continue To App’ from our website to be taken directly to its page in Google Play; an agreement pop-up window with app permissions will then appear, asking you for approval before installing it onto your device and being accessible from its home page once downloaded and installed.
