What Juices Are Acidic?

The pH of the foods you eat can affect the pH balance of your body. Too much acid can wear down the enamel on your teeth, so certain fruits with high acidic content should be consumed in moderation. The pH scale ranges from 0 to 14; the lower the pH number of a food, the more acidic it is. Add this to my Recipe Box.

Lemon and Lime Juices

With a pH of 2 to 2.60, lemon juice is one of the most acidic juices in a typical diet. The small yellow fruits are grown in warm climates and are used to make sauces, lemonade and lemon desserts like tarts and pies. Limes, the small green fruit closely related to lemons, are also acidic. They have a pH of 2 to 2.35. Both juices are high in vitamin C.

Pineapple Juice

The tropical pineapple is large and juicy, which makes it ideal for juicing. Fresh and canned juice have a sweet tart flavor and are used in cocktails, baked goods and served straight. The pH of pineapple juice ranges from 3.30 to 3.60. Canned pineapple juice contains just over 5 teaspoons of natural sugars per 12 ounces.

Orange and Grapefruit Juices

A common breakfast meal companion, orange and grapefruit juices are both acidic. The pH of orange juice ranges from 3.30 to 4.19. California orange juice can be slightly more acidic than Florida juice, though many store brands are a mixture of both. Grapefruit juice from the large, yellow-orange citrus fruit, has a pH balance of 3. Grapefruit juice cocktails, however, will have a lower pH and higher sugar content than straight grapefruit juice, due to additional juices and sweeteners added during processing.

Cranberry Juice

The small, tart, red berry is grown in the northwest and northeast regions of the U.S. It is consumed straight or with liquor and blended with sugars and other juices for cranberry juice cocktail. Unsweetened cranberry juice has been recommended for urinary tract health. The pH of cranberry juice is between 2.45 and 3.
