The Nutritional Truth About Persimmon Phosphorus
Persimmons are a nutritional powerhouse, packed with vitamins, minerals, and fiber. Among these essential nutrients is phosphorus, a mineral vital for various bodily functions, including bone health and energy production. While persimmons do contain phosphorus, the amount is modest, which can be a key consideration for those monitoring their mineral intake, such as individuals with kidney health concerns.
How Much Phosphorus is in a Persimmon?
The amount of phosphorus in a persimmon varies depending on its variety and size. Nutritional data from the University of Rochester Medical Center shows that a raw Japanese persimmon (approximately 168 grams or 2.5" in diameter) contains around 28.56 mg of phosphorus. In contrast, a smaller American persimmon (about 25 grams) contains only about 7 mg of phosphorus. These figures illustrate that, on a per-fruit basis, persimmons are not a significant source of this mineral.
The Low-Phosphorus Advantage
For many, the lower phosphorus content is a benefit. Health resources like DaVita, which specializes in kidney care, point out that persimmons are naturally low in phosphorus and fat. This makes them a viable and flavorful option for individuals on a controlled diet for kidney disease, where managing phosphorus levels is crucial. The form of phosphorus in plants, known as phytate, is also less bioavailable to the human body than inorganic phosphorus added to processed foods. This means a smaller percentage of the phosphorus in a persimmon is absorbed by the body compared to the same amount found in a packaged food.
Persimmons vs. High-Phosphorus Foods
To put the phosphorus content of persimmons into perspective, consider how it compares to some foods known for their higher mineral levels. This table illustrates the difference in milligrams (mg) per serving.
| Food Item | Approximate Phosphorus per Serving |
|---|---|
| Japanese Persimmon (1 fruit, ~168g) | ~28 mg |
| Cheddar Cheese (1 oz) | ~145 mg |
| Beef, eye round (roasted, 3 oz) | ~178 mg |
| Lentils (cooked, 1 cup) | ~356 mg |
| Yogurt, low fat (1 cup) | ~356 mg |
A Wealth of Other Nutrients
Beyond their modest phosphorus content, persimmons are celebrated for their rich profile of other beneficial compounds. This includes:
- Vitamins: An excellent source of Vitamin A, Vitamin C, and some B vitamins like folate.
- Fiber: A single fruit provides a significant amount of dietary fiber, promoting healthy digestion and helping to regulate blood sugar levels.
- Antioxidants: Rich in powerful antioxidants, including carotenoids and flavonoids, which combat free radicals and reduce oxidative stress.
- Potassium: Contains a good amount of potassium, an important electrolyte for heart and nerve function.
Key Benefits Beyond Phosphorus
The full spectrum of nutrients in persimmons contributes to several health benefits, which include:
- May benefit heart health: The flavonoid antioxidants in persimmons have been linked to improved heart health, lower blood pressure, and reduced LDL ('bad') cholesterol.

- Supports vision: The high Vitamin A and beta-carotene content is crucial for maintaining healthy eyesight and protecting against age-related macular degeneration.
- Anti-inflammatory effects: Powerful antioxidant compounds, such as carotenoids and flavonoids, help reduce inflammation throughout the body.
Conclusion
In summary, yes, persimmons have phosphorus, but they are not considered a high-phosphorus food. The concentration is relatively low, making them a safe and nutritious choice for most people, including those on low-phosphorus diets. Their true value lies in the rich combination of fiber, vitamins, and antioxidants they offer, which collectively support overall wellness, from heart health and digestion to vision. When eaten as part of a balanced diet, persimmons provide a sweet, healthy boost of nutrients without contributing excessive amounts of any single mineral.
