It’s not so much the citric acid in fruits that are ‘bad’ for Candida sufferers, but the fact that they’re alkalizing foods plus most are high in sugar. Lemons are also alkalizing, but are an excellent detoxing agent; other fruits are not mainly because of their high sugar content.
One of two major problems with soda is the sugar content, and it doesn’t matter if you drink a diet soda or not, the types of sugar substitutes used will feed the Candida just the same as regular sugar will.
The other problem is that they’re carbonated, this means that carbon dioxide gas was used to make the drink, which means that the gas was dissolved in the liquid. Carbon dioxide is nothing but a waste product, in other words just another toxin for the liver to deal with in addition to all the toxins the Candida releases. In addition, when mixed with water it forms carbonic acid which depletes minerals from the teeth and bones.
