Is watermelon acidic? A simple answer to this question will be no. Watermelon is one of the fruits with low levels of acidity. Watermelon is often perceived as a highly acidic fruit due to its vibrant color and taste.  The scientific evidence tells us that it only has a pH range of 5.18 to 5.60 which is a sign of low acidity. This level of pH is not particularly high, so you can include watermelon in a stomach-friendly diet.

This article aims to explore the relationship between watermelon and acidity while analyzing factors such as its pH levels, nutritional profile, and health benefits. 

What Makes Watermelon Low-Acidic?

    You know the pH scale ranges from 0-14, any level that falls above 7 is known as alkaline in nature and less than 7 is acidic. However, the level of acidic nature varies according to the pH scale. pH of a fruit can make a profound impact on its flavor, preservation, and how it interacts with the body.

    Watermelon Acidic

    As mentioned earlier the pH range of watermelon falls between 5.18 to 5.60 which makes it one of the lower acidic fruits. The range will vary depending on factors including the production method and variety of fruit. Due to its low acidic nature, people have been eating melons to reduce acid reflux. The acidic level of watermelon is generally well tolerated by most individuals. 

    Factors Influencing The pH of Watermelon

      Watermelon is a sweet and hydrating fruit with a lot of health benefits. It does possess a degree of acidity but several factors can influence its pH level. The acidic content of a ripe watermelon will be different from unripened fruit.

      The pH will also vary based on the variety of the fruit, the growing conditions, and cultivation practices. It is known that certain varieties of watermelon display different levels of acidity.

      Some varieties exhibit high levels of pH compared to others. The green-banded watermelons show slightly heightened acidity compared to green watermelons. The sweetness of the fruit will also help you determine the pH level, if the melon is sweet normally the acidity will be lower. Despite its acidity, watermelons are considered a healthy fruit. Let’s explore the health benefits of them in the coming section.
