Lemons and limes are vibrant citrus fruits that many people use in a variety of dishes, beverages, and desserts. They’re also some of the main, naturally occurring sources of citric acid — a sour-tasting component of citrus fruits. But did you know you can also find it in other fruits, too? Here, we break down which fruits have citric acid and some of the health benefits of eating them.
Fruits With Citric Acid
Wondering which fruits have citric acid? Research published in September 2023 and another study published in 2023 both confirm that lemons and limes have a high amount of citric acid. However, the UW Hospital Metabolic Stone Clinic also adds that lemons and limes have the most citric acid compared to any other citrus fruits and juices.
But that doesn’t mean they’re the only fruits to have citric acid in them. In addition to lemons and limes, the following fruits are also good sources of citric acid:
- Oranges
- Grapefruits
- Tangerines
- Pomelos
- Pineapple
- Strawberries
- Raspberries
- Cranberries
- Cherries
- Tomatoes
Artificial Uses of Citric Acid
While fruits contain naturally occurring sources of citric acid, this acid can also come in artificial forms. Research published in December 2023 suggests that the antibacterial and antioxidant properties of citric acid can preserve foods by keeping them fresh for a longer period, and also enhance the flavor of foods.
But that’s not all. ChemicalSafetyFacts.org explains that a variety of cleaning products also include citric acid, as this acid can help remove hard water buildup and stains. They also say that cosmetic and skincare products use citric acid as a way to help brighten the skin and reduce dark spots.
Benefits of Citric Acid
Now that you know which fruits have citric acid, you may be wondering why citric acid is beneficial for your body. Turns out, citric acid offers several health benefits.
One study published in January 2024 reports that citric acid supports gut health by increasing the amount of good bacteria in your gut. A study published in June 2022 notes that citric acid also serves as an antioxidant, a substance that helps protect your cells from cell damage, which can help lower the risk of chronic illnesses like heart disease and cancer. The same study adds that citric acid has also shown evidence of boosting immunity and protecting your liver and brain health.
Research published in September 2023 explains that citric acid, when applied topically to your skin (such as in the form of AHA serums), can help remove dead skin cells and improve skin health. Harvard Health Publishing also adds that drinking a half cup lemon juice (which is high in citric acid) mixed in water daily can also help reduce the risk of developing kidney stones.
How to Incorporate More Citrus Fruits in Your Diet
Mayo Clinic explains that citrus fruits aren’t just high in citric acid, they’re also a good source of vitamin C — a nutrient that boosts your immune system and contributes to healthy skin and bones. If you’re ready to add more citrus fruits to your eating plan, consider the following ideas on how to increase your intake:
- Make lemonade at home by freshly squeezing lemons.
- Add fruits like strawberries or raspberries to your smoothies.
- Create your own fruit salad that incorporates foods like cranberries or pineapples.
- Keep your fridge or pantry stocked with tangerines and oranges for a quick snack.
