Have you ever wondered why some fruits make your mouth pucker? Many fruits contain acid, which gives them their tangy taste. But not all fruits are created equal when it comes to acidity.
Citrus fruits like lemons, limes, and oranges are among the most acidic fruits, with pH levels ranging from 2 to 4 on the pH scale. These fruits are packed with vitamin C and other antioxidants, making them great for your health despite their high acidity.
But citrus fruits aren’t the only ones with a sour kick. Berries like strawberries and blueberries also contain acid, though not as much as citrus.
Even fruits you might not expect, like pineapples and grapes, have acidic properties.
Understanding fruit acidity can help you make better choices for your diet, especially if you have certain health concerns.
