Here’s a quick science lesson: Every food and drink has a pH level, from 0 (very acidic) to 14 (very basic, or alkaline). Normal drinking water, for its part, usually has a pH of 7. Alkaline ...
Postprandial (i.e., after a meal) alkaline tide lasts until the acids in food absorbed in the small intestine reunite with the bicarbonate that was produced when the food was in the stomach. Thus, the alkaline tide is self-limited and normally lasts less than two hours. Postprandial alkaline tide has also been shown to be a causative agent of ...
Lemon juice tastes sour because it contains 5% to 6% citric acid and has a pH of 2.2 (high acidity). Plants contain pH-dependent pigments that can be used as pH indicators , such as those found in hibiscus , red cabbage ( anthocyanin ), and grapes ( red wine ).
Alkaline ash is produced by fruits and vegetables, except cranberries, prunes and plums. Since the acid or alkaline ash designation is based on the residue left on combustion rather than the acidity of the food, foods, such as citrus fruits, that are generally considered acidic are actually considered alkaline producing in this diet.

The lower the pH, the higher the concentration of bicarbonate will be. This shows how a lower pH can lead to higher alkalinity if the amount of bicarbonate produced is greater than the amount of H + remaining after the reaction. This is the case since the amount of acid in the rainwater is low.
The results may taste a little different -- fish cooked in the oven is flaky, whereas fish cooked by lemon juice (a.k.a. ceviche) has a more raw-tasting consistency -- but the process is the same.
