    Hello,


    I'm looking for substitutes to caffeine. A friend told me that vegetable juices raise one's alkaline levels. Raised alkaline levels are supposed to increase oxygen levels and higher energy levels.


    Is any of this true?


    Are there other substitutes to caffeine for raising one's energy levels and alertness?

    No, alkaline diets are a con.

    Alternatives for caffeine are available, but I'm not the best person to ask. I'm a coffee addict!

    I'm afraid I can't help either on the caffeine substitute question, but your comments about alkalinity are interesting as there are some popular myths abroad.

    As PhDemon says, this alkaline diet stuff is pseudoscience and in fact scientifically illiterate. There are people who claim that lemons are alkaline! Obviously they have never heard of citric acid.

    What they do is muddle up the acidity or alkalinity of the ash from burning the foodstuff with the acidity or alaklinity of the foodstuff itself. The two are totally unrelated. Generally speaking if you burn plant material to ash you get an alkaline ash, whereas if you burn flesh to ash you get a more acid ash.

    Also it is rubbish to think that you can alter the pH of the body by what you eat. pH is very tightly regulated by the body, precisely because it would directly affect the CO2 dissolved in the blood. You can't just change it by eating different food.

    If you are a daily caffeine drinker, any of the above substitutes will take time to work as your body deals with caffeine withdrawal.
