Is Passionfruit a Significant Source of Calcium?
When assessing if a food is a good source of a specific mineral, it is crucial to look at its quantity relative to the daily recommended intake. In the case of calcium, which is vital for bone and teeth health, blood clotting, and nerve function, passionfruit does not stand out as a primary source. A standard 100-gram serving, which consists of the edible pulp and seeds, provides just 12 milligrams of calcium. This equates to approximately 1% of the average adult's recommended daily value, a figure that is significantly lower than that found in dairy products, fortified foods, or other fruits known for their higher calcium content.
While passionfruit does contain a multitude of important minerals, including magnesium and phosphorus, which are also crucial for bone density, its low calcium concentration means it should not be relied upon to meet your daily calcium needs. For those specifically looking to increase their calcium intake, focusing on other foods is a more effective strategy.
The Full Nutritional Profile of Passionfruit
Although not a calcium powerhouse, passionfruit boasts a rich nutritional profile that contributes to overall health in many other ways. Calorie for calorie, this small fruit is incredibly nutrient-dense.
- High in Dietary Fiber: Passionfruit is an excellent source of fiber, with a 100-gram serving offering a substantial amount. This fiber supports healthy digestion, promotes a feeling of fullness, and can help regulate blood sugar levels.
- Rich in Vitamins C and A: The fruit is packed with Vitamin C, a powerful antioxidant that supports the immune system and promotes healthy skin. It also contains high levels of Vitamin A, which is essential for good vision, immune function, and cell growth.
- Potassium: Passionfruit contains a significant amount of potassium, a mineral that helps regulate blood pressure and supports heart health.
- Antioxidants: The pulp and seeds are loaded with beneficial plant compounds, such as polyphenols and carotenoids. These antioxidants protect the body from cell damage caused by free radicals and have anti-inflammatory effects.
