Manganese
Manganese is a trace mineral present in blackberries that is important for bone development, metabolism, and protecting cells from oxidative damage. It assists in the formation of collagen and aids in proper wound healing.
Other Micronutrients
A handful of blackberries also offers smaller amounts of other beneficial micronutrients, including:
- Potassium
- Calcium
- Magnesium
- Folate
Antioxidant Power and Health Benefits
Blackberries are renowned for their high concentration of antioxidants, especially anthocyanins, which give them their deep, dark color. These powerful plant compounds help combat oxidative stress caused by free radicals, which can contribute to aging and chronic diseases.
- Anti-inflammatory effects: Research suggests that the antioxidants in blackberries can help reduce inflammation throughout the body, potentially offering protective effects against conditions like arthritis.
- Brain health: Studies have shown that the compounds in blackberries may improve cognitive function and protect the brain from age-related decline.
- Heart health: The anthocyanins and fiber in blackberries can support a healthy heart by helping to manage blood pressure and cholesterol levels.
- Digestive health: The dietary fiber promotes regularity and supports a healthy gut microbiome by feeding beneficial bacteria.
