1. Understanding Acidity in Foods
Acidity in food is determined by its pH level, a measure of how acidic or alkaline a substance is. The pH scale ranges from 0 to 14, with 7 being neutral. Foods with a pH below 7 are considered acidic, while those above 7 are alkaline or basic. The concentration of acidic compounds in foods significantly influences their taste and potential effects on your body. For example, citrus fruits, known for their tartness, have a low pH due to high concentrations of citric acid. Understanding the pH level of different foods can help you make informed dietary choices to maintain a balanced and healthy diet.
The pH scale ranges from 0 to 14, where values below 7 are acidic, 7 is neutral, and above 7 are alkaline.
- Acidic: 0.0 – 6.9
- Neutral: 7.0
- Alkaline (or basic): 7.1 – 14.0
The human body maintains an average pH of around 7.4. Saliva, when not eating or drinking, should stay close to the neutral range of 6.5 to 7.5 pH. Foods are broken down in the body into compounds that can alter acidity levels. A diet high in acidic foods may lead to conditions like acid reflux or heartburn and affect gastrointestinal health.
