Coca-Cola or Pepsi
As well as all the bacteria doing their thing in your mouth there is also an enzyme called amalyse, this plays an important role in the processing of organic matter placed within our mouth.
the effects of pH values on the reaction rate of enzymes can be seen here. basicaly at pH 2.5 the reaction rate is next to nothing, im not sure if coke actualy denatures the amalyse or just slows the reaction rate down.
It doesn't matter because your salivary amylase just digest a very small quantity of starch when you eat it and has an optional effect (that's why you can sometimes eat and digest without chewing and swallowing directly). The salivary amylse is inactivated right after entering in the stomach anyway(because o the pH & pepsin degradation as you showed).
The important amylase is in your pancreas and is secreted in the gastro instestinal tract in much higher quantity.
plaque feeds on sugar
exactly that's what really damage teeth. Your teeth get the acidity of coke for a second before you swallow. Just after your salivary secretion being around pH 7/8 re-sustain an overall normal pH. That's why we can't say coke's acidity has an important effect; whereas sugar remains in the mouth.
Go on for phosphorous
It doesnt matter about amaylse?? hmm then why do we produce it?? either substantiate your facts with some founded logic or do not whetspin theories and it is not inactivated, the term you are looking for is denatured.
What function, apart from the breakdown of starch does amalyse perform? maybe there is some link to the ratio of good/bad bacteria in your mouth, try looking this up (i dont wanna waffle here )
OK a 101 lesson .
plaque feeds on sugar, coke IS a sugar solution- so coke IS the plaques major food source in a dilute state with a real nice pH value to the solution to enable and encourage further growth.
furthermore the amalyse in the mouth is denatured or has its reaction rate slowed considerably and cannot combat the effect of the intensified bacteria.
some quotes to put sugar/acid effects on, not just our teeth but the whole body into some context.
The average 12 ounce cola has about 150 calories and over an ounce (9 tsps) of refined sugar, a 12 ounce up-cola has 71/2 teaspoons of sugar. Dr. A. Thrash, M.D., found that 24 teaspoons of sugar in on day destroys 92% of the body's ability to destroy bacteria.
"All kinds of soft drinks are very acidic, especially colas. In order to neutralize a glass of cola, it takes 32 glasses of high ph alkaline water."It is well known by the medical profession that disease loves acid. In fact, a physician from Loma Linda University said in a speech that if we could get our cells to maintain a normal ph (slightly alkaline), cancer could not grow in our bodies."
Dental cavities: Often associated with carbonated beverage. This association is important because the amount of sugars that are consumed is important in forming caries, which is when a cavity effects only the enamel, the outer protective layer of a tooth.
Francisco Contraries, M.D., of the Contraries Cancer Clinic in Kiajuana, Mexico said, "Cancer is like a plant cell; it can't live in an oxygen-rich environment. cola drinks make our bodies poor in oxygen. Cancer is the second cause of death in America. The average American is consuming 800 or more soft drinks annually. Be more responsible for your own life; doctors have no responsibility for another's health."
ok phospouros.. in particular in the form of phosporic acid (wow acid again )
just some cut and paste so not my words but word of credible doctors.
A three year study of over 1,000 men with a history of kidney stones showed: "There was a clear-cut difference in the group's experiences, with much less renal colic in the men who had avoided soft drinks. Of those who continued to use soft drinks, there was also a big difference in outcome depending upon the nature of the soft drink consumed.Soft drinks acidified with phosphoric acid were the worst offenders. Colas of all kinds, of course, are well known for their high phosphoric acid content."
My file is full of examples of Americans with soft bones (dissolved, I believe, by their phosphoric acid consumption) any my heart-felt concern for fetuses is now a reality - many are being born without face bones, with missing ribs, with fewer than normal carpal bones, and so forth. Do we really care? Do we care enough to change our lifestyle? I sincerely hope so.If changes are not made by millions soon, Dr. James Beasley's prediction can be upon us. He said, "If Americans do not change their eating and drinking habits, within twenty years we will have nutritional obliteration." I see that as a very viable possibility.
Effect Of Phosphorus: The phosphorous that is found in the fizz and bubbles emitted from soft drinks fights with hydrochloric acid in the stomach and causes the stomach to be ineffective. When the stomach can’t digest food, the person will have indigestion, gassiness, or bloating
The increased risk of bone fractures and osteoporosis: The large amounts of sugar, bubbles caused by carbon dioxide, and phosphoric acid that are found in soft drinks remove nutritious minerals from bones allowing the bones to become weak and increasing the risk for them to break.
phosporous messes with your mitochondria and affects the production of DNA (i think quite an important function) phosporous causes abnormalitys in unborn children and weak brittle bones at all ages especialy the older people get and the calcium / phosporous ratio changes naturaly anyway.
hmm caffiene next?? - what a lovely alkaloide
and wonko and ratz are spot on - clean your fucking teeth kids at least twice a day, but dont swallow that toothpaste (far too much phosporous in there )
It doesnt matter about amaylse?? hmm then why do we produce it??
i guess it to boosts the digestion efficiency but it's really optional. If each of our secretions were necessary to live we would die really fast
either substantiate your facts with some founded logic or do not whetspin theories and it is not inactivated, the term you are looking for is denatured.
my mother language is not english but you get your enzyme inactivated by denaturation process of course. I dont think we should go into the details of the denaturation process now lol.
The link between coca cola/acid and cancer is really funny, it made my day
Nah seriously cancer is the 1st cause of mortality in france and we have one of the lowest consumption in developed countries
Too bad we dont recover cancer by stoping drinking coke lol
Coca cola..
i guess it to boosts the digestion efficiency but it's really optional. If each of our secretions were necessary to live we would die really fast
yeah..?? the same as if each of the living organisms on the planet was neccesary the planet would die real fast.. and dont forget you can live with only 1 leg but quality of life can deteriarate even faster. a strange statement you make.
i guess
dont guess - look it up and come back to me when you researched it.
The link between coca cola/acid and cancer is really funny, it made my day
why is proven scientific research funny, do you mean you dispute it, please once again, come back to me when you've researched it.
Nah seriously cancer is the 1st cause of mortality in france
really, thats good as most countrys (developed) the biggest killer is heart disease.. I know france followed this pattern in 2004 but i have no up to date global figures. ( in 2004 deaths by cause in France - Malignant neoplasms = 2,383,000 compared to Cardiovascular diseases 2,575,000)
we have one of the lowest consumption in developed countries
True, France is the biggest consumer of fruit juice in the europe market.
and the largest purchasers of dental products... (the dental bit is a joke, maybe true though i dunno.. )
[code:1]DRINK TITRATABLE ACIDITY pH RELATIVE RISK
Grapefruit Juice 9.3 3.2 High
Orange Juice 4.8 3.8 High
Apple Juice 4.5 3.3 High
Cola 0.7 2.5 Medium
Diet Cola 0.5 2.9 Medium [/code:1]
Since it became duo discussion

i dont know what you mean by the planet would die, but my statement means that not all of our organs & secretion are NECESSARY to live and even to live with very good quality of life. Many ppl live with 1 kidney a totally normal life, same for all those champions injured or suffering cancers that recovered and beat records. Human body knows how to deal with many insufficiencies (of course not all) by enhancing other capacities get it ?

there are thousands factor leading to hundreds of cancers some are important some others are just insignificants, i dont need to research it because i have been studying that factors for many years and coke acidity hasnt anything to do with an established cause of cancer by the whole scientific community. some examples for you: UV exposure, smoke, hereditary/geneticaly factor... Send me your article it will be funny to read it

My statement was written at present tense and is based on 2007 last statistics, cancer>cardiovascular diseases i'm sure you can find it somewhere

I did not mentioned fruit juice, maybe i'll have a look later but none of my teacher has ever said me such statement about fruit juices. I guess some are full of shits and some others are healthy. But overally i always learnt they are mostly healthy full of vitamins with anti-oxydation properties.
ok i'm not dentist specialist, some of your explanation were interesting, coca cola probably has a little role in damaging teeth but again it's insignificant compared to everything we eat every day, as soon as you brush your teeth you'll keep them healthy.
@others: Can continue via pm to not bother you guys
uhhhhhhhh pepsi?
bodz its not duo discussion, anyone can fell free to put any facts across, maybe dispel some myths about things..
but hey i dont GAF really, i drink the crap and i still know how bad it is for you and have researched into the effects at a cellular level. lets hope you never make cheif medical examiner or youll be telling us that ciggarettes are ok if you get some fresh air after smoking..
lol man, dont take it so seriously, but you compare things you cannot. Smoking is the harmfullest thing you can do to your body, it has been studied in hundred thousands studies, you cannot compare its effect with drinking coke, even to joke (i hope so). people must know that when they smoke or drink much alcohol, THEY WILL DIE because of this, or at least will likely get ill because of this. So we can keep arguing about coke and orange juice
Pepsi Twist
