Alkaline vs Acidic. Aloe Vera? Lemon Juice? ACV?

I've been a little confused with the advice on the balance between alkaline vs acidic. I know most of our body body fluids should be around a neutral pH of 7 and the blood being slightly basic and our intestines being acidic. I've heard to try to eat 70% alkaline resulting and 30% acidic resulting foods, and it seems that our diets being too acidic is what most people are worrying about. Apparently too much acidic foods 'allows harmful bacteria to flourish' and harms absorption of nutrients etc. However I'm hearing that is incorrect in the case of candida, and that an acidic environment is what causes candida to regress to a harmless yeast form, and allows beneficial bacteria to survive.

I've also heard Apple Cider Vinegar is great for candida, which makes sense considering its acidity, however its actually alkaline forming in the body, correct? Same with Lemon Juice. And Aloe Vera juice is also supposed to be alkaline, along with omega 3's, olive oil, tea, ginger, whey protein and plenty of other foods oils and supplements that are recommended for candida and leaky gut.

If we are trying to keep acidity high to protect against candida, while also not inflaming a leaky gut, what should we be eating?
