I explained the reasons behind why you want to increase your pH when you have a UTI in The pH Connection post, and this one is specifically about how to change your diet to help make that happen.
Stop all the processed food, ladies, and soft drinks and coffee/black tea and sugar and chocolate and tomatoes and salsa and steak. Red meat is highly acid-forming in your system, and so are sugars and starches and most dairy. Dairy and caffeine are bladder irritants in their own right: it’s just that you don’t notice it when you don’t have an infection. Members of the nightshade family are alkaline-forming, but they’re still upsetting to a bladder infection more often than not. Also, fermented food/drinks should be avoided in most cases.
Now for the good news…
