Gustav III Of Sweden's Coffee Experiment
Gustav III of Sweden's coffee experiment was a purported twin study ordered by the king to study the health effects of coffee. The authenticity of the event has been questioned. The primitive medical study, supposedly conducted in the second half of the 18th century, failed to prove that coffee was a dangerous beverage. Background In Sweden coffee was banned by royal decree across three different reigns, in five separate periods between the 1750s and the 1820s: 1756-61, 1766-69, 1794-6, 1799–1802 and 1817-1823. Coffee first arrived in Sweden around 1674, but was little used until the turn of the 18th century when it became fashionable among the wealthy. In 1746, a royal edict was issued against coffee and tea due to "the misuse and excesses of tea and coffee drinking". Heavy taxes were levied on consumption, and failure to pay the tax on the substance resulted in fines and confiscation of cups and dishes. Later, coffee was banned completely; despite the ban, consumption cont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gustav III
Gustav III (29 March 1792), also called ''Gustavus III'', was King of Sweden from 1771 until his assassination in 1792. He was the eldest son of Adolf Frederick of Sweden and Queen Louisa Ulrika of Prussia. Gustav was a vocal opponent of what he saw as the abuse of political privileges seized by the nobility since the death of King Charles XII. Seizing power from the government in a coup d'état, called the Swedish Revolution, in 1772 that ended the Age of Liberty, he initiated a campaign to restore a measure of Royal autocracy, which was completed by the Union and Security Act of 1789, which swept away most of the powers exercised by the Swedish Riksdag (parliament) during the Age of Liberty, but at the same time it opened up the government for all citizens, thereby breaking the privileges of the nobility. A bulwark of enlightened absolutism, Gustav spent considerable public funds on cultural ventures, which were controversial among his critics, as well as military attemp ...

18th Century In Sweden
18 (eighteen) is the natural number following 17 and preceding 19. In mathematics * Eighteen is a composite number, its divisors being 1, 2, 3, 6 and 9. Three of these divisors (3, 6 and 9) add up to 18, hence 18 is a semiperfect number. Eighteen is the first inverted square-prime of the form ''p''·''q''2. * In base ten, it is a Harshad number. * It is an abundant number, as the sum of its proper divisors is greater than itself (1+2+3+6+9 = 21). It is known to be a solitary number, despite not being coprime to this sum. * It is the number of one-sided pentominoes. * It is the only number where the sum of its written digits in base 10 (1+8 = 9) is equal to half of itself (18/2 = 9). * It is a Fine number. In science Chemistry * Eighteen is the atomic number of argon. * Group 18 of the periodic table is called the noble gases. * The 18-electron rule is a rule of thumb in transition metal chemistry for characterising and predicting the stability of metal complexes.

Twin Studies
Twin studies are studies conducted on identical or fraternal twins. They aim to reveal the importance of environmental and genetic influences for traits, phenotypes, and disorders. Twin research is considered a key tool in behavioral genetics and in related fields, from biology to psychology. Twin studies are part of the broader methodology used in behavior genetics, which uses all data that are genetically informative – siblings studies, adoption studies, pedigree, etc. These studies have been used to track traits ranging from personal behavior to the presentation of severe mental illnesses such as schizophrenia. Twins are a valuable source for observation because they allow the study of environmental influence and varying genetic makeup: "identical" or monozygotic (MZ) twins share essentially 100% of their genes, which means that most differences between the twins (such as height, susceptibility to boredom, intelligence, depression, etc.) are due to experiences that one ...

Fika (Sweden)
Coffee culture is the set of traditions and social behaviors that surround the consumption of coffee, particularly as a social lubricant. The term also refers to the cultural diffusion and adoption of coffee as a widely consumed stimulant. In the late 20th century, espresso became an increasingly dominant drink contributing to coffee culture, particularly in the Western world and other urbanized centers around the globe. The culture surrounding coffee and coffeehouses dates back to 16th-century Turkey. Coffeehouses in Western Europe and the Eastern Mediterranean were not only social hubs but also artistic and intellectual centres. In the late 17th and 18th centuries, coffeehouses in London became popular meeting places for artists, writers, and socialites, as well as centres for political and commercial activity. In the 19th century a special coffee house culture developed in Vienna, the Viennese coffee house, which then spread throughout Central Europe. ''Les Deux Magots'' in P ...

History Of Coffee
The history of coffee dates back to centuries of old oral tradition in Africa. Coffee plants grew wild in Ethiopia and were widely used by nomadic tribes for thousands of years. Sufi monasteries in Yemen employed coffee as an aid to concentration during prayers. Roasting the seeds was not a way to serve coffee until the 1400s. /sup> During the cultivation, brewed coffee was reserved exclusively for the priesthood and the medical profession; doctors would use the brew for patients experiencing a need for better digestion, and priests used it to stay alert during their long nights of studying for the church. Coffee later spread to Europe in the early 16th century; it caused some controversy on whether it was halal in Ottoman and Mamluk society. Coffee arrived in Italy the second half of the 16th century through commercial Mediterranean trade routes, only being served to the wealthy. Central and Eastern Europeans learned of coffee from the Ottomans. By the mid 17th century, it had ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Health Effects Of Caffeine
Caffeine is a central nervous system (CNS) stimulant of the methylxanthine class. It is mainly used recreationally as a cognitive enhancer, increasing alertness and attentional performance. Caffeine acts by blocking binding of adenosine to the adenosine A1 receptor, which enhances release of the neurotransmitter acetylcholine. Caffeine has a three-dimensional structure similar to that of adenosine, which allows it to bind and block its receptors. Caffeine also increases cyclic AMP levels through nonselective inhibition of phosphodiesterase. Caffeine is a bitter, white crystalline purine, a methylxanthine alkaloid, and is chemically related to the adenine and guanine bases of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). It is found in the seeds, fruits, nuts, or leaves of a number of plants native to Africa, East Asia and South America, and helps to protect them against herbivores and from competition by preventing the germination of nearby seeds, as well as ...

Health Effects Of Tea
Although health benefits have been assumed throughout the history of using ''Camellia sinensis'' as a common beverage, there is no high-quality evidence that consuming tea confers significant benefits other than possibly increasing alertness, an effect caused by caffeine in the tea leaves. In clinical research conducted over the early 21st century, tea has been studied extensively for its potential to lower the risk of human diseases, but there is no good scientific evidence to indicate that consuming tea affects any disease or improves health. In regions without access to safe drinking water, boiling water to make tea is effective for reducing waterborne diseases by destroying pathogenic microorganisms. By constituents or substances Aluminum, iron and other metals Tea drinking accounts for a high proportion of aluminum in the human diet. The levels are safe, but there has been some concern that aluminum traces may be associated with Alzheimer's disease. A 2013 study addi ...
