Caffeine is an odorless alkaloid. It is a natural ingredient that is found in the green coffee bean. It is also found in a number of other plants, including tea, cocoa, kola, guarana, and yerba mate. Caffeine, used by people is the largest psychoactive stimulant, which speeds up the central nervous system.
Caffeine affects all of us differently. Where some might be able to fall asleep soon after drinking coffee, some might not.
Recent international studies have shown that caffeine has demonstrated protective effects against Parkinson’s disease and Alzheimer’s disease when consumed in moderation.
Caffeine enters your blood stream through the lining of your mouth, throat, and stomach. Your stomach contents can account for different effects of caffeine. It can take up to forty-five minutes for the majority of caffeine to be absorbed and the effects can last up to three hours.
A cup of coffee contains 98.6% water, which means 1.4% of that cup is dissolved coffee solids.  Caffeine is 1.2% of that 1.4% coffee.

Incidentally,  the US, drinks the most coffee, 400 million cups per day.

Caffeine Facts

The Mayo Clinic says most healthy adults can safely consume up to 400 mg of caffeine each day.

Caffeine is
a central nervous system stimulant that makes us feel alert. It can also improve our mood and is associated with a reduced risk of depression. It can also increase our adrenaline level, which can leave us more irritable, anxious, and far more emotionally-charged. Caffeine has been shown to improve certain types of memory in some, but not all studies. Controlled amounts of caffeine can boost notable performance gains for athletes. Some studies also indicate caffeine is effective to increase long term memories. Although ingesting too much caffeine makes it difficult to focus on anything.

There is some evidence that caffeine, when combined with certain pain-relieving medications like acetaminophen, the main active ingredient in Tylenol, and aspirin, helps those medications take effect quicker, last longer, and increases their effects.
Excedrin contains caffeine.

Here are a few common sources of caffeine:

Most 12-ounce cups of coffee contain 90 to 120 mg of caffeine,
One 12-ounce cup of Starbucks contains about 260 mg,
Dunkin Donuts has 215 mg,
One 2-ounce shot of 5 hour energy contains about 215 mg,
One 12-ounce cup of McDonald's coffee has about 109 mg,
One 8-ounce can of Red Bull contains 80 mg,
One cup of brewed black tea contains about 67 mg,
One shot of espresso contains about 71 mg, (a latte is espresso plus steamed milk - cappuccino is espresso plus milk and foam),
One 12-ounce can of diet Coke has 46 grams of caffeine,
One 12-ounce can of regular Coke has 34 grams of caffeine.

This is a climbing plant in the maple family, native to the Amazon basin and especially common in Brazil. Guarana features large leaves and clusters of flowers, and is best known for its fruit, which is about the size of a coffee bean. As a dietary supplement, guarana is an effective stimulant and its seeds contain about twice the concentration of caffeine found in coffee beans (about 2–4.5% caffeine in guarana seeds compared to 1–2% for coffee beans). As with other plants producing caffeine, the high concentration of caffeine is a defensive toxin that repels herbivores from the berry and its seeds.

If you look at the contents of any energy drink, chances are that guarana is listed as one of the main ingredients. European missionaries in 17th-century Brazil recorded the native people’s use of the berry, noting that it not only gave them energy, but allowed them to go for days without feeling hungry. It became a colonial trading commodity that was said to help protect the body from illness, but too much of it was known to cause insomnia.

The caffeine that is found in the guarana berry is thought to be different from the caffeine found in coffee. Guarana contains chemical components called tannins, which are thought to produce a longer-lasting effect than caffeine from other sources. For centuries, guarana berry seeds have been powdered or smoked in a long process that is done by hand. Drinking properly prepared guarana can be central to formal occasions and gatherings, where groups of people pass around a calabash bowl.

Fifteen More Coffee Facts

Coffee is the second largest traded commodity in the world (oil is the largest).

  1. There are two types of oils in coffee, good oils and bad oils. The good oils are good for your body and your health, the bad oils may give you ulcers and stomach problems. To avoid the bad oils in coffee use paper filters to minimize the effects.
  2. Mocha Java Coffee has no chocolate in the Mocha or Java bean. Mocha is the name of the port in Yemen, where all African coffee beans are traded and transported. Java is the name of an island in Indonesia where the Java bean originates. Both coffees are dark bean and provide a bold coffee, when you mix the two together you get Mocha Java coffee.
  3. Coffee starts out as a yellow berry, ripens into a red berry, and is then harvested by hand. Through water soaking process the red berry is de-shelled and leaves the green coffee bean. This bean then dries in the sun for 3-5 days before bagging.
  4. In Africa, coffee beans are soaked in water mixed with spices and served as candy to chew.
  5. Brazil is the largest coffee producer in the world and the US is the largest coffee consuming country in the world.
  6. There are 65 countries in the world that grow coffee and they are all located along the equator.
  7. Black coffee with no additives contains no calories.
  8. There are two types of coffee plants, Arabica and Robusta.
  9. Espresso Coffee has one third of the caffeine content of a cup of regular coffee.
  10. James Mason invented the coffee percolator on December 26, 1865.
  11. Instant coffee was invented in 1901 by a Japanese American chemist, Satori Kato. In 1906 English chemist, George Constant Washington claimed he invented instant coffee.
  12. Melitta Bentz a housewife from Dresden, Germany, invented the first coffee filter in 1908.
  13. It takes five years for a coffee tree to reach full maturity, coffee trees can live up to 100 years and the average yield from one tree equals about one pound of roasted coffee.
  14. A regular 6oz cup of coffee contains about 150 milligrams of caffeine.
  15. Robusta coffee beans have twice as much caffeine as Arabica beans, but are of less quality.

After as little as 10 minutes, the caffeine concentration in your blood reaches half the maximum concentration, which is enough to have an effect. The caffeine reaches maximum levels, making you most alert after 45 minutes. Depending on how fast or slow your body is able to break down the drug, you could feel the effects of caffeine for 3 to 5 hours.

Coffee contains hundreds of different compounds. These include many antioxidants that protect our bodies from damaging chemicals called free radicals. These molecules cause aging and are associated with illnesses such as cancer and heart disease. NIH studies show that coffee drinkers have a reduced risk of Alzheimer's, Parkinson's, type 2 diabetes and many other diseases.

Energy Drinks Unmasked

A friend of mine, Jeff wondered what is in energy drinks that makes them work and are they safe. That sent me scouring my personal stash and the web for answers. The following excludes the larger volume drinks, such as Monster, Red Bull, etc., and offerings from Pepsi, Coke, and others. Those all have their own host of reasons to avoid, but that is for another discussion.

Most of the two ounce shot energy drinks contain varying amounts of taurine, caffeine, sucralose (splenda), niacin, vitamin B12, B6, folic acid, sodium, acai fruit extract, guarana, and many other ingredients that are almost impossible to spell or pronounce. Others have green tea, L-carnitine, ginseng, yohimbine, and all contain water and natural and artificial ingredients (whatever that means). Most have zero calories listed. Many have warning not to take more than one every four or six hours (likely in self defense from the FDA).

Many are described as an energy shot to enhance concentration and improve performance. They do not specify what performance. A number of them are designed specifically for hangover relief, and a few diet suppression. The only difference I could find in these ingredients was more vitamin B12 (in one type 10,000% of the daily value). Some of the names are 'pure energy, 5-hour energy', 'eternal energy, 'extra energy', 'Extra strength energy', 'java-mite', 'XX Energy', 'high energy', 'hangover recovery, 'diet aid', etc.

The majority of the dozen I checked come in little white two ounce bottles covered with shrink wrap covers. Interesting that so many have the identical bottle (with the exception of the bottom indents) and wrapper type regardless of manufacturer. Could find no common denominator other than that. Prices ranged from as low as $.88 to $3.98 for the same size. Interesting to note that one of the most popular and most expensive, 5 hour energy has the least liquid at 1.93 ounces.

Most sites agreed the biggest reason for the jolt is the large amount of caffeine, about as much as two cups of coffee in a small two ounce dose. Studies show they are no better as a pickup than coffee, although they are concentrated in less liquid as well as more convenient and quicker to drink. Annual revenues for energy drinks is about 13 billion dollars.

Bottom line, the caffeine is the kicker, the vitamins go out in the urine, the other ingredients are for flavor, preservatives, and color. None have proven to be bad for us, probably due to the trace amounts contained. None are good for children for the same reasons as coffee. In spite of a few rantings by the usual fear mongers, these have yet to be proven unsafe, with the exception of occasional jitters common to those who do not well tolerate caffeine. In my case, they seem to work as advertised and do not provide any physically noticeable high or low.

Caffeine Shots

This is a bit scary. Aeroshots are caffeine inhalers. They contain a quick-dissolving powder.

Take a puff and you get an instant burst of caffeine. Each cartridge contains 100mg of caffeine, or about as much as a large coffee. Each holds about 6 to 8 shots. They look like shotgun shells and the target audience is college students trying to stay up late to cram for exams, or to supplement drinking binges. It is legal, but not what you might want to see around your children.
