Understanding the Iron Content of Santol
While sources like Specialty Produce state that santol is a source of iron, quantitative analysis reveals it is present in very modest amounts. The edible pulp of 100 grams of santol contains approximately 0.20 to 0.42 milligrams of iron, depending on the variety. To put this into perspective, the recommended daily intake of iron varies significantly by age and sex, with adult men needing around 8 mg and adult women aged 19-50 requiring 18 mg. This means a 100-gram serving of santol would only provide a small fraction of the daily iron requirement.
The Importance of Non-Heme Iron and Vitamin C
The iron found in plant-based foods like santol is known as non-heme iron, which is not as readily absorbed by the body as the heme iron found in animal products. This is where santol’s other nutritional strengths become relevant. Santol is also known to be a good source of vitamin C, a powerful antioxidant. Vitamin C is crucial because it significantly enhances the body's absorption of non-heme iron when consumed in the same meal. Therefore, eating santol with other plant-based iron sources could boost overall iron uptake.
How Santol Stacks Up: A Comparison of Iron in Fruits
To better understand santol's contribution, comparing its iron content to other foods is useful. The following table illustrates how a 100-gram serving of santol compares to other plant and animal-based iron sources.
| Food (100g serving) | Iron Content (mg) | Iron Bioavailability |
|---|---|---|
| Santol | ~0.20-0.42 | Non-heme (Enhanced by Vit C) |
| Spinach (cooked) | ~2.7 | Non-heme |
| Lentils (cooked) | ~3.3 | Non-heme |
| Beef (cooked) | ~2.0-3.0+ | Heme |
| Dried Apricots | ~2.6 | Non-heme |
| Tofu | ~2.9-3.0 | Non-heme |
As the table shows, while santol does contain iron, it is not a primary source compared to iron-fortified cereals, legumes like lentils, or animal proteins. For those looking to increase their iron intake, other options may be more effective. However, santol's other nutritional benefits, including its vitamin C, can play a supportive role in a balanced diet.
A Complete Nutritional Snapshot of Santol
Beyond its small contribution of iron, santol offers several other beneficial nutrients, making it a healthy addition to your diet.
- High in Vitamin C: This antioxidant is vital for immune function, skin health, and boosting iron absorption.
- Rich in Fiber: Santol is a great source of dietary fiber, which aids digestion, promotes gut health, and can help regulate blood sugar levels.
- Good Source of Potassium: Potassium is an essential mineral that helps regulate fluid balance, heart rate, and blood pressure. Some varieties contain high levels of potassium.
- Other Minerals: The fruit also contains trace amounts of calcium and phosphorus, important for bone health.
Health Benefits Beyond Iron
Santol is valued in folk medicine for its various therapeutic properties, extending beyond its mineral content. The fruit is believed to have anti-inflammatory and antioxidant properties. Traditional uses include remedies for digestive issues and fever. Its rich antioxidant profile helps protect the body's cells from damage caused by free radicals.
How to Incorporate Santol into Your Diet
Santol can be enjoyed in a variety of ways, depending on your taste preferences for its sweet and sour flavor. It can be eaten fresh, added to salads, or processed into jams and jellies. In Filipino cuisine, it is famously used in dishes like sinigang (a sour soup) and in dishes cooked with coconut milk. However, it is important to remember that the large seeds are inedible and can cause intestinal obstruction if swallowed. Be sure to discard them properly before consumption.
Conclusion
In conclusion, does santol have iron? Yes, it does, but only in small, supplementary amounts. It should not be relied upon as a primary source for the mineral. Its real strength lies in its broader nutritional profile, particularly its high vitamin C and fiber content. For individuals seeking to boost their overall health, santol is a great choice. For those needing a significant iron boost, it should be paired with other, more iron-dense foods. Its natural vitamin C content makes it an excellent companion to non-heme iron sources to maximize absorption. As with any fruit, enjoy it in moderation as part of a varied and balanced diet.

Safety Warning
The large, hard seeds of the santol fruit are indigestible and pose a choking hazard or risk of intestinal blockage. They must always be removed before eating the fruit or preparing it for consumption.
