Does Diet Coke Dehydrate u?

Will it dehydrate u or just not hydrate u as well as water?

Diet Coke has 45.6mg of caffeine per 12oz of drink (see website below). I woud think that this would have a dehyrative effect overall.

what about cafeeine free?

[slipshady]

says it all for itself. i would stick to water if your looking for hydration though

I've heard that carbonated beverages interfere with protein absorption, I dunno if I believe it though. I love that new 7-up plus....

I've gotta look into that--I've heard the same, so I avoid it around times I'm eating. It would be nice to know for sure though. Anybody have any references on this??

I looked into this again and found (the quick summary is that the carbonation may cause incomplete or improper digestion, so you may not get all the benefits of what you are eating):



From Flex, June, 1994

Q | Are carbonated beverages good for bodybuilders?

A | Carbonated beverages are often viewed as digestive aids because the gas from the carbonation causes distension of the stomach and intestines. This distension is sensed by the gastrointestinal (GI) system and causes an increase in motility--meaning the food that's in the stomach passes through the GI tract at a faster rate. This may be good for decreasing indigestion but bad for enhancing digestion and absorption of nutrients--particularly amino acids from protein.

Carbonation may interfere with absorption because the higher acidity of such beverages inhibits normal secretion of stomach enzymes, such as proteases, which break down protein into amino acids. Carbonated beverages also may somehow force much of the food consumed to sit in the higher part of the stomach, where the enzymes are not found, preventing the normal breakdown of protein.

If food moves more rapidly through the stomach, there is less time for enzymes to do their work. Also, if fewer enzymes are doing their work, some of the protein you've eaten may not get properly digested.

Another problem with drinking a carbonated beverage during a meal is that you may feel less satiated afterward. This was discovered in a study of patients with indigestion and constipation. Carbonated water taken with meals reduced the study subjects' indigestion and constipation, but they were less satiated than when they drank plain water with food.

AND from somewhere else:

Concern over drinking carbonated beverages has been escalating in recent years. It’s rumored to inhibit athletic performance and has been linked to osteoporosis. But is there any truth to these rumors?

Carbonation in sodas comes from dissolving carbon dioxide in water, a process also used for sparkling waters. While many people seem to enjoy the effect of carbonation in their beverages, one can’t help wonder how this odd sensation affects the body.

Most of the carbon dioxide (CO2) is lost before the soda even reaches your mouth. Of that ingested, most (around 70%) is carried by the red blood cells in the form of bicarbonate. Since this is the natural bodily process of metabolizing carbohydrates, the effect of added CO2 is not drastic for the body to deal with.

Some studies in the early 1990’s suggested a link between carbonation and osteoporosis due to urinary excretion of calcium. However, a study published in the American Journal of Clinical Nutrition disproved this claim showing instead that this was due more in part to caffeine in soda.

Further health claims, such as carbonation neutralizing stomach acids and impairing the breakdown and absorption of essential nutrients, seem to hold more validity. Since you are adding bicarbonate to the blood stream, it should somewhat upset the body’s chemical balance. For this reason, it’s logical to assume that the common claim of carbonation effecting performance during athletics has some relevance. While its effects are probably not great enough to worry about in general, it is certainly good protocol for athletes to refrain from drinking carbonated beverages when attempting to achieve optimal performance.

When it comes to soft drinks, carbonation can hardly be considered a concern since virtually everything else on most soda’s ingredient lists is more cause for concern. But since soft drinks are so unhealthy in general, this should be considered more fuel to the fire in your fight to avoid them whenever possible.

Will it dehydrate u or just not hydrate u as well as water?

i guess if you drink enough of it becuase of caffeine content.
