November 8 Information
Which part of foods increases (if any) the acidity in the stomach more than others, proteins, carbs or fats? -- 93.126.116.89 ( talk) 03:43, 8 November 2020 (UTC)
- I am surprised to find the answer is fats.
[1]. Though some foods have intrinsic acid, like
acetic acid or
citric acid.

- Graeme Bartlett the "mild" food acids are no match for the pH ~1 of the hydrochloric acid of the stomach. Roger (Dodger67) ( talk) 16:04, 8 November 2020 (UTC)
- What is increased is not so much the
acidity (lowered pH), but the absolute amount of acid. --

- Correct, important distinction. Stomach acid is way more acidic than anything you can safely swallow, and when you add something with a higher pH to a solution (remember, higher pH means less acidity), it raises the solution's pH. However, the stomach is there to digest stuff, and when food enters, it secretes more acid. This simply works to move the pH of the stomach contents back towards 1. "Burning" feelings are typically caused by acid getting into someplace it shouldn't due to acid reflux. -- 47.152.93.24 ( talk) 19:44, 8 November 2020 (UTC)
