    According to the book Body Restoration by Drs Lebowitz & Kapadia: “Caffeine is the most consumed, socially-acceptable stimulant in the world. Approximately 90% of adults in the world consume caffeine in their daily diet. More than million people in the US drink coffee on a regular basis, averaging 2 cups per day. While my mother could.   Linked to three of the most consumed beverages (coffee, tea, and cacao) are the most popular methylxanthines: caffeine, theophylline, and theobromine (Table 1). Caffeine is the most abundant methylxanthine in coffee, its level being smaller in chocolate than in coffee.

    The metabolism and kinetics of 14 C-labeled theophylline have been studied after intravenous doses of mg to healthy subjects, keeping to their usual diets after 7 days of abstention from methylxanthine-containing foods and beverages and again after such abstention while taking caffeine and theophylline in tablet form. The metabolism of oral 14 C-theophylline has also been investigated. The methylxanthines, theophylline, and dyphylline are used in the treatment of airways obstruction caused by conditions such as asthma, chronic bronchitis, or emphysema. Caffeine (present in coffee) and theobromine (present in chocolate) are also methylxanthines. Theophylline is the most well known and most commonly used methylxanthine.

Tavazzi / [et al.] Antioxidative Phenolic Compounds in Green-Black Tea and Other Methylxanthine-Containing Beverages / Ulrich H. Engelhardt, Christiane Lakenbrink and Svenja Lapczynski ; Theobromine, like caffeine, and also like the asthma-improving methylxanthine theophylline, belong to the chemical group know as xanthine alkaloids. Chocolate products contain some caffeine, but not nearly enough to explain the attractions, fascinations, addictions and effects of chocolate. Theobromine can form a metabolite of caffeine.

Caffeine is usually the methylxanthine compound that is present at the highest levels in foods and beverages. Scientific evidence indicates that a moderate daily caffeine consumption is not associated with adverse health effects in healthy adult populations [1,18,19], although notable behavioral effects occur at low to moderate doses (50– mg) [].Cited by: 7.

Caffeine-found in tea, coffee, mate, cola beverages, cocoa, and chocolate products-is an integral part of the diet of many people. Caffeine answers questions for a broad range of readers interested in the effects beverages and foods containing this dietary methylxanthine have on human health, nutrition, and physiological functioning.

Samples of common types of methylxanthine-containing beverages and foods consumed in Spain were analyzed to determine their content.

Caffeine was the methylxanthine that was most found in the samples investigated. Instant coffees gave the highest caffeine percentage (18–44 mgg−1).Cited by: 7. The Methylxanthine Beverages and Foods: Chemistry, Consumption, and Health Effects.

Abstract. This work investigated the contents of methylxanthines in 25 types of stimulating foods available in the Brazilian market, totaling samples, from which coffee, tea, and chocolate beverages were made using the most common preparation methods in the country.

Among solid foods, soluble coffee powders showed the highest mean content of caffeine ( ± mg/ g), while chocolate powders.

Methylxanthines are a group of naturally occurring substances found in coffee, tea, chocolate and related foodstuffs. Naturally occurring theophylline (1,3-dimethylxanthine), and its ester derivative aminophylline, are the only compounds in clinical use.

They are chemically similar to caffeine. shows methylxanthine concentration in second and third brews of tea leaves, which is the preferred brewing method in Asia. It is crucial to accurately determine methylxanthine concentrations in brewed teas before making generalizations about the amount of tea consumed and its effect on health.

Caffeine as well as theobromine, paraxanthine and theophylline, are part of the methylxanthine family and can be labeled as psychoactive stimulants.

These substances in varying amounts and complexes are found in coffee, tea, chocolate, cola, yerba mate and guarana. The food sources are presented in alphabetical order, beginning with products naturally containing methylxanthines: cocoa, coffee, guaraná, maté, tea, and yoco.

They are used in a variety of food products such as dairy products, beverages, baked products, confections and pet foods. Food colors may have toxic effects on the human body.

The increasing use of caffeine and related methylxanthines in various foods and beverages consumed by children and adolescents cause concern. NNT recommends that a full hazard characterization of caffeine and related methylxanthines should be performed with the aim to reach a conclusion about the upper safe level of intake of these compounds.

Abstract Methylxanthines, namely caffeine, theobromine and theophylline are found in several beverages and food products such as coffee, cocoa, tea and cola drinks. These substances can provide benefits to humans but also prove harmful mainly when consumed in high amounts.

With contributions from the fields of pharmacy, dietetics, and medicine, Handbook of Food-Drug Interactions serves as an interdisciplinary guide to the prevention and correction of negative food-drug interactions. Rather than simply list potential food-drug interactions, this book provides explanations and gives specific recommendations based on th4/5(1).Abstention from methylxanthine‐containing foods and beverages led to a significant decrease in the urinary elimination half‐life of 14 C from to hr (p methylxanthine, and 1,3‐ldimethyluric acid.
