In an attempt to snag a piece of the purity pie, Pepsi launched Crystal. Its new cola was clear, caffeine-free and a total failure. It was hard for consumers to think of cola as a clear liquid. Which was not helped by the fact that Crystal didnât taste like cola at all. In fact, no one really knew what it tasted like â just that it was not good. Two years later, the product was pulled from the shelves. But Pepsi didnât give up completely on its quest for purity.
Why You Need Stomach Acid and What Happens When You Neutralize It. The importance of stomach acid is well-documented. Stomach acid is essential for the absorption of Vitamin B12 which plays key role in the normal functioning of the brain and nervous system, and in the formation of blood.
The idea here is that it is very difficult for the stomach to produce stomach acid. The normal acidity of blood is about pH7, but the acidity of stomach acid can be as low as pH1 - that means that hydrogen ions (which create acidity) are a million times more concentrated in the stomach than in the bloodstream. acid is required to sterilise the stomach and kill bacteria and yeast that may be ingested and. 2  an acid environment is required for the absorption of certain micronutrients, in particular divalent and trivalent cat-ions such as calcium, magnesium, zinc, copper, iron, selenium, boron and so on.
