Wood Apple's Macronutrient Profile
When examining the nutritional value of a wood apple, it's essential to look at its macronutrient composition, as this forms the bulk of the fruit's energy and structural components. Per 100 grams of edible pulp, wood apple is a moderate source of calories, with estimates ranging from 75 to 137 kcal depending on the source and ripeness.
The fruit is a good source of carbohydrates, which provide energy for the body's functions. Carbohydrate content can range from approximately 18g to over 30g per 100g serving. Much of this is complex carbohydrates and dietary fiber, rather than simple sugars, which contributes to its low glycemic index and beneficial effects on blood sugar regulation.
Protein content in wood apple is modest but notable for a fruit, typically ranging from 1.8g to 3.5g per 100g. It is also very low in fat, with less than half a gram per 100g serving.
Essential Vitamins Found in Wood Apple
Wood apple is a valuable source of several key vitamins that are crucial for maintaining overall health. These include:
- Vitamin C: An excellent source of vitamin C, wood apple acts as a powerful antioxidant, protecting against free radical damage and supporting the immune system. Some research indicates levels up to 900 mg per 100g in fresh pulp, though more commonly reported figures are lower.
- B Vitamins: The fruit is rich in B vitamins, including riboflavin (B2) and thiamine (B1), which play a vital role in cellular metabolism and energy production.
- Beta-Carotene (Precursor to Vitamin A): Wood apple contains beta-carotene, which the body converts into vitamin A. This nutrient is essential for maintaining healthy vision and skin.
Key Minerals in Wood Apple Pulp
Beyond vitamins, the wood apple is packed with essential minerals that contribute to various bodily functions. A 100g serving can provide significant amounts of the following:
- Calcium: A remarkable source of calcium, wood apple supports strong bone and dental health. Some studies report up to 190 mg per 100g.
- Phosphorus: This mineral works with calcium to build strong bones and teeth and is essential for energy production.
- Iron: Wood apple provides iron, a key component for red blood cell production and preventing anemia. Its iron content is particularly bioavailable when combined with its high vitamin C content.
- Potassium: An important electrolyte, potassium in wood apple helps regulate fluid balance, maintain proper nerve and muscle function, and regulate blood pressure.
- Magnesium and Zinc: These minerals also contribute to overall metabolic health, with some studies highlighting their presence.
A Comparative Nutritional Look: Wood Apple vs. Apple
While the name suggests a similarity, the nutritional profiles of a wood apple ($Limonia acidissima$) and a common apple ($Malus domestica$) are quite different. This table highlights some key distinctions per 100g serving.
| Nutrient | Wood Apple (approximate) | Apple (average, common) |
|---|---|---|
| Calories | 120 kcal | 52 kcal |
| Carbohydrates | 20.8 g | 13.8 g |
| Dietary Fiber | 4.6 g | 2.4 g |
| Protein | 3.5 g | 0.3 g |
| Vitamin C | High (around 8-10 mg or more) | Moderate (around 4.6 mg) |
| Calcium | Very High (190 mg) | Low (6 mg) |
| Iron | Moderate (1.6 mg) | Low (0.1 mg) |
| Specialty Compounds | Tannins, flavonoids, coumarins | Quercetin, catechin |
As the table shows, the wood apple is significantly richer in protein, fiber, and specific minerals like calcium and iron. Its unique phytochemical compounds also set it apart, contributing to its distinct health benefits.
Wood Apple's Role in Digestive and Immune Health
One of the most celebrated aspects of wood apple's nutritional value is its effect on digestive health. The high dietary fiber content aids in regulating bowel movements, providing relief from both constipation and diarrhea. Its high tannin content, especially in the unripe fruit, is noted for its astringent and antimicrobial properties, which help to combat dysentery and intestinal inflammation.
The fruit's immune-boosting properties are primarily due to its high levels of vitamin C and other antioxidants. These compounds help protect the body against infections and strengthen its natural defense mechanisms against viral, fungal, and bacterial pathogens.
Conclusion: A Nutrient-Dense and Versatile Fruit
In conclusion, the nutritional value of a wood apple goes far beyond its curious, hard exterior. This fruit is a rich source of dietary fiber, complex carbohydrates, and a surprising amount of protein for a fruit. It is particularly noteworthy for its mineral profile, providing excellent levels of calcium, iron, and potassium, which are all vital for health. Coupled with a potent dose of vitamins, especially vitamin C, and a host of powerful antioxidants, wood apple is a health powerhouse with significant benefits for digestive, immune, and cardiovascular systems. Incorporating this unique fruit into your diet, whether as fresh pulp, juice, or in jams, offers a flavorful and nutritious way to support overall well-being.
How to Consume Wood Apple to Maximize Nutritional Benefits
Fresh Pulp Consumption
