For these natural sources of caffeine, there is no regulatory provision requiring that a food label identify the presence of caffeine nor state the amount of caffeine present in the food. Consumption
Global consumption of caffeine has been estimated at 120,000 tonnes per year, making it the worlds most popular psychoactive substance. This amounts to an average of one serving of a caffeinated beverage for every person every day. The consumption of caffeine has remained stable between 1997 and 2015. Coffee, tea and soft drinks are the most important caffeine sources, with energy drinks contributing little to the total caffeine intake across all age groups. Religions
Until 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). 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 Churchs health guidelines prohibit alcoholic drinks, smoking or chewing of tobacco, and hot drinks – taught by Church leaders to refer specifically to tea and coffee. "Gaudiya Vaishnavas generally also abstain from caffeine, because they believe it clouds the mind and overstimulates the senses.
In phonetics, denasalization is the loss of nasal airflow in a nasal sound, such as a nasal consonant or a nasal vowel. That may be due to speech pathology but also occurs when the sinuses are blocked from a common cold, when it is called a nasal voice, which is not a linguistic term. Acoustically, it is the "absence of the expected nasal resonance." The symbol in the Extended IPA is ⟨◌͊⟩. When one speaks with a cold, the nasal passages still function as a resonant cavity so a denasalized nasal [m͊] does not sound like a voiced oral stop [b], and a denasalized vowel [a͊] does not sound like an oral vowel [a]. However, there are cases of historical or allophonic denasalization that have produced oral stops. In some languages with nasal vowels, such as Paicĩ, nasal consonants may occur only before nasal vowels; before oral vowels, prenasalized stops are found. That allophonic variation is likely to be from a historical process of partial denasalization. Similarly, several languages around Puget Sound underwent a process of denasalization about 100 years ago. Except in special speech registers, such as baby talk, the nasals [m, n] became the voiced stops [b, d]. It appears from historical records that there was an intermediate stage in which the stops were prenasalized stops [ᵐb, ⁿd] or poststopped nasals [mᵇ, nᵈ]. Something similar has occurred with word-initial nasals in Korean; in some contexts, /m/, /n/ are denasalized to [b, d].
