E.Coli is an acid bacteria that can synthesize its own nutritional characteristics in an acidic environment. Since cranberry acidifies urine, everytime we use it, we do offer E.Coli a favorable terrain to reproduce.
Why does cranberry have this reputation?
There is a small anti-adherence effect associated with cranberry although in case of infection, there are other properties of cranberry that nullify it.
We already know that to combat bacteria presence we need an alkaline environment. The metabolic rate of E. coli is actuallly slowed down in alkaline urine – which is why bacteria spend much more time multiplying.
E.coli (and other uropathogenic bacteria) develop when they find favorable conditions for their reproduction.
- we drink cranberry juice or another urine acidifier
- in the short period of time it takes for uric acid to form in the bladder, E.Coli rushes in a frantic multiplication, doubling its number in 20-30 minutes
- when urine becomes more alkaline, bacteria become semi-dormant, slowing their reproduction (almost 100%)
- if we intake cranberry juice or tablets this process begins again and again
It is known that many people get bacterial cystitis when they are dehydrated since this causes a large amount of urea (uric acid) to be produced in the urine. Cystitis occurs because bacteria find the perfect environment to proliferate.
By avoiding cranberry or vitamin C in the form of ascorbic acid, alcohol, red meat, coffee and by making the urine more alkaline, we can eliminate the acids that are one of the nutritive resources for bacteria.
At first cranberry seems to help
When cranberry is taken to fight cystitis, at the beginning, all bacteria that cannot survive in an acidic environment are eliminated since in all the colonies there are always some weaker bacteria.
In this way, cranberry seems to help initially although this phase is followed by a worsening of the symptoms.
Bacteria that survive will multiply and since they adapt quickly to acidic conditions, the resulting colony will be much more resistant to the acidic environment.
A little advice
Cranberry does not seem to be an effective solution against cystitis even if it has a little anti-adhesion action due to PACs (ProAntoCianidias) as it is nullified because of the acidity it causes.
How to take advantage of this anti-adhesion effect without acidifying the urine?
The answer is simple: D-Mannose. This simple sugar has the same action of PACs, allowing the elimination of bacteria with the urine. plus it does not acidify the urine and, in addition, the anti-adhesion effect it generates is between 10 and 50 times stronger than with cranberry.
