Science debates health risks of coffee.?

Question

I've seen this headline every 6 months or so for a couple of decades now, and each new "scientific study" debunks the previous one. How are we supposed to believe the scientific community about important things like global warming when they can't seem to definitivly answer a simple question like is caffeine good or bad for you? Unfortunately I think that humans are only clever enough to ask the questions but lack the where-with-all to answer them.

Answer 1

Exactly. Remember how they changed their theories about eating eggs 10 times over? Or about drinking wine? Or about how many times you should eat meat per week? Every single one of such theories and many more gets shuffled, changed, and redone 40 times per decade. And in the end? In the end my friend your health depends primarily on your mental state. If you're mentally sound, if you feel ok with yourself, chances are your overall health will be great regardless of how many coffees you drink or whether you drink red wine or not.

Answer 2

You are right one way but other way you are wrong as well !It all depends on the issue you are working !Definition of Science is it is nothing but finding the ultimate TRUTH ! May be for years together and different theories be practiced but HUMAN is always got benefit What you are talking about is an INDIVIDUAL thing !See every rule has an exception !But that does not mean the rule is wrong !Many factors works together for one event to happen !No doubt that the "DOUBTFUL" thinking leads to the TRUTH but for that one should not criticize insted appreciation!People in whom taking of coffee from generation to generation may not cause harm as the whole system is adjusted to this ! Because of wasteful use of the energy that we have on our planet HUMAN will suffer most>have you observed that many spices of sparrow and such small birds are not seen now a day which usually were singing all day ! This must be because of the harmful effect of all radio magnetic waves of mobile cell phones and TV channels waves !Similarly global worming is not a joke !Because we dont know that why it is not acceptable to many like you !For this you have to go deep and should cultivate that knowledge !I dont say that there are no one to make and keep you deaf and dum !But you yourself must realise what is what!See intelligency is not KNOWLEDGE you have !It is a ability of imagination and try to make come true.I feel sorry if i have hurt you but TRUTH remains TRUTH and it must be told even if it hurts !if satisfies you may give me credit of best answer !I am always YouRsmE

Answer 3

You are right about one thing; science cannot know everything, and should never go unchallenged.
I think the reason that it's not clear whether caffeine is good or bad for you is, that the effects are not major. It can make you feel a little better or a little worse; it neither causes nor cures nor treats illness. That's about it.

Answer 4

Well, what I do is alternate, some weeks I drink only coffee, next week only wine, next is whole wheat bread, then eggs morning, noon and night....then I drive to and from the store and next I ride my bycycle...so far its seems I've managed to stay in the safe part of the circle cause I'am still here...so I think that the word for the day is,,"alternate",,stay cool..pass the word..."altteeerrrnaate"...thanks

Answer 5

Coffee has this inside it :

Caffeine is a xanthine alkaloid compound that acts as a stimulant in humans. The word comes from the Italian term for coffee, caffè.[1] Caffeine is also called guaranine when found in guarana, mateine when found in mate, and theine when found in tea. It is found in the leaves and beans of the coffee plant, in tea, yerba mate, and guarana berries, the kola nut, the Yaupon Holly, and in small quantities in cocoa. Overall, caffeine is found in the beans, leaves, and fruit of over 60 plants, where it acts as a natural pesticide that paralyzes and kills certain insects feeding on the plants.

Caffeine is a central nervous system (CNS) stimulant, having the effect of temporarily warding off drowsiness and restoring alertness. Beverages containing caffeine, such as coffee, tea, soft drinks and energy drinks enjoy great popularity; caffeine is the world's most widely consumed psychoactive substance, but unlike most other psychoactive substances, it is legal and unregulated in nearly all jurisdictions. In North America, 90% of adults consume caffeine daily.[2] The U.S. Food and Drug Administration lists caffeine as a "Multiple Purpose GRAS Food Substance".[3]

Many natural sources of caffeine also contain widely varying mixtures of other xanthine alkaloids, including the cardiac stimulants theophylline and theobromine and other substances such as polyphenols which can form insoluble complexes with caffeine

Caffeine is a plant alkaloid, found in numerous plant species, where it acts as a natural pesticide that paralyzes and kills certain insects feeding upon them.[5] The most commonly used caffeine-containing plants are coffee, tea, and to a small extent cocoa. Other, less commonly used, sources of caffeine include the yerba mate[6] and guaraná plants, which are sometimes used in the preparation of teas and energy drinks. Two of caffeine's alternative names, mateine[7] and guaranine,[8] are derived from the names of these plants.

The world's primary source of caffeine is the coffee bean (the seed of the coffee plant), from which coffee is brewed. Caffeine content in coffee varies widely depending on the type of coffee bean and the method of preparation used;[9] even beans within a given bush can show variations in concentration. In general, one serving of coffee ranges from 40 milligrams, for a single shot (30 milliliters) of arabica-variety espresso, to about 100 milligrams for a cup (120 milliliters) of drip coffee. Generally, dark-roast coffee has less caffeine than lighter roasts because the roasting process reduces the bean's caffeine content.[10][11] Arabica coffee normally contains less caffeine than the robusta variety.[9] Coffee also contains trace amounts of theophylline, but no theobromine.

Tea is another common source of caffeine. Tea usually contains about half as much caffeine per serving as coffee, depending on the strength of the brew. Certain types of tea, such as black and oolong, contain somewhat more caffeine than most other teas. Tea contains small amounts of theobromine and slightly higher levels of theophylline than coffee. Preparation has a significant impact on tea, and color is a very poor indicator of caffeine content.[12] Teas like the green Japanese gyokuro, for example, contain far more caffeine than much darker teas like lapsang souchong, which has very little.

Caffeine is also a common ingredient of soft drinks such as cola, originally prepared from kola nuts. Soft drinks typically contain about 10 to 50 milligrams of caffeine per serving. By contrast, energy drinks such as Red Bull contain as much as 80 milligrams of caffeine per serving. The caffeine in these drinks either originates from the ingredients used or is an additive derived from the product of decaffeination or from chemical synthesis. Guarana, a prime ingredient of energy drinks, contains large amounts of caffeine with small amounts of theobromine and theophylline in a naturally occurring slow-release excipient.[13]

Chocolate derived from cocoa contains a small amount of caffeine. The weak stimulant effect of chocolate may be due to a combination of theobromine and theophylline as well as caffeine.[14] Chocolate contains too little of these compounds for a reasonable serving to create effects in humans that are on par with coffee. A typical 28-gram serving of a milk chocolate bar has about as much caffeine as a cup of decaffeinated coffee.
