The Core Nutritional Ingredients of Loquat Fruit
Loquats (scientific name: Eriobotrya japonica) are a low-calorie, nutrient-dense fruit that delivers a wealth of vitamins and minerals in each serving. A typical 100-gram serving (about 3.5 ounces) contains roughly 45–70 calories, making them a healthy addition to any diet. Their nutritional profile consists of essential components that aid in various bodily functions, from boosting immunity to improving digestion.
Vitamins
Loquats are an excellent source of several key vitamins:
- Provitamin A (Beta-Carotene): The vibrant orange-yellow color of the fruit indicates its high content of carotenoids, particularly beta-carotene. Our bodies convert this compound into Vitamin A, which is crucial for healthy vision, skin, and immune function.
- Vitamin C: This powerful antioxidant helps protect the body from free radical damage, supports the immune system, and promotes skin health.
- B-Complex Vitamins: Loquats also provide small amounts of B vitamins like folate (B9), niacin (B3), and thiamine (B1), which are essential for metabolism and energy production.
Minerals
In addition to vitamins, loquats are a good source of several vital minerals:
- Potassium: An important electrolyte that helps regulate blood pressure and supports heart health.
- Manganese: A trace mineral vital for bone development, metabolism, and antioxidant defenses.
- Calcium and Phosphorus: These minerals work together to build strong bones and teeth.
- Magnesium: Involved in hundreds of biochemical reactions in the body, including muscle and nerve function.
Other Beneficial Compounds
Beyond the basic vitamins and minerals, loquats offer additional compounds with powerful health effects:
- Dietary Fiber: Loquats are rich in soluble and insoluble fiber. Soluble fiber, especially pectin, helps regulate bowel movements and can aid in lowering cholesterol, while insoluble fiber promotes gut health and prevents constipation.
- Antioxidants: The fruit is packed with antioxidants like carotenoids (beta-carotene, lutein, zeaxanthin) and polyphenols, which fight oxidative stress and cellular damage.
The Ingredients of Loquat Leaves
While the fruit is the most commonly consumed part, loquat leaves are also prized in traditional Chinese medicine for their medicinal properties. They contain different bioactive compounds than the fruit and are typically brewed into teas or syrups.
- Triterpene Acids: Compounds found in the leaves, such as ursolic acid, have been shown in some animal studies to have anti-inflammatory effects.
- Other Phytochemicals: Leaf extracts contain anti-diabetic and antioxidant agents that have been used to treat respiratory ailments like coughs and bronchitis.
