Caffeine negates water intake?

Someone just told me that the water in coffee or soda doesn't count as water intake, that it negates it. You'd have to drink extra water to make up for the caffeine. Anybody ever heard of this? I thought water was water?

    Caffeine is a diuretic but it doesn't make you pee more than the volume of liquid in the drink. So it still counts imo.

    What they told you is totally, completely, entirely, wholly, undeniably and indisputably false.

    What if you take a sip of coffee and then a sip of water? Does the caffeine in the coffee also affect the straight water since they reach the stomach about the same time?

    No. Your body will utilize water from any source the same way it will pure water. Water in coffee, water in Coke, water in food...to your body it's just water. As long as it gets into your body it will hydrate you.

    I have heard that nonsense before. It's not true. All non-alcoholic beverages count toward fluid intake. Whether you choose to log them is up to you, but it won't stop your body from using the water.

    The whole point of drinking more water than your body needs is to create a diuretic affect.

    They're saying that the caffeine dehydrates your body

    I have read things about that as well. I have no doubt other ingredients in beverages (such as high sodium or sugar) may have some effect. But I do not spend time nit-picking about it. I drink a few cups of French press coffee in the morning, and other low-calorie beverages during the day, but always have 1/2 cup of water before and after each.

    It can if you consume enough. But you have to consume a lot, more than most people would ever consider.

    I've been seeing ads that say caffeinated drinks hydrate you as well as water does. Is this true?

    It is true that caffeinated fluids can contribute to your daily fluid requirement.

    Drinking caffeine–containing beverages as part of a normal lifestyle doesn't cause fluid loss in excess of the volume ingested. While caffeinated drinks may have a mild diuretic effect — meaning that they may cause the need to urinate — they don't appear to increase the risk of dehydration.

    Yeah.. Apparently she's a gym trainer. I hate confrontation but I hate bad information more.

    Caffeine does have a small diuretic effect, so if you were taking caffeine pills or eating a lot of chocolate, you could experience a small net water loss. However, the amount of water in a cup of coffee is much more than the amount of water lost due to the effects of caffeine, so you do not need to worry about dehydrating your body if you are drinking coffee. Of course, caffeine can have other negative effects on the body, so pay attention to what your body is telling you when you consume it.

    Ditto to the others. Yes, caffeine is a diuretic but no, it is not so powerful that the caffeine in coffee or soda will cause you to lose all (or even most of) the water in the drink.

    As long as your pee tells you that you're hydrated, that's all that matters.

    Oh! Also, being a trainer at a gym rarely indicates that a person understands nutrition (but almost always indicates someone who thinks they do).

    ETA: for that matter, it doesn't even always indicate that they know what they should about exercise.

    If it did, I would have died of dehydration decades ago.

    In my opinion theres no reason to track water intake as long as urine is clear and light.

    You get water from foods, drinks, etc. It's pretty difficult to track all of that exactly. Drink enough liquids to have clear urine and you're fine.

    Don't sweat the small stuff. Yes it's a diuretic, but it should be fine if you don't have any issues with urine retention/dehydration, etc.

    Do not confront her. Just sip a bottle of water in front of her to prove to her that you can drink water.

    That's what I thought as well. That it does dehydrate but only if you drink a lot of it. And not necessarily soda since that has less caffiene than coffee/espresso, depending.

    That said, I don't count it as my water intake simply because it isn't water imo. While it contains water, it's also caramel coloring, citric acid, etc. Everyone's different though, and I drink about two liters of water in addition to other liquids like almond milk, the water in veggies and fruits, etc.
