All About Juicy Blackberries

Blackberries are a delicious group of dark blue, black, and purple fruits from the Rubus species grown mostly in parts of North America and Europe. It has a sweet, sometimes tangy taste depending on the berry. But each berry is packed with antioxidants, minerals, and other nutrients like iron, vitamins C, E, and K, calcium, and manganese in every bite. (1,2)

And humans have been enjoying this antioxidant-packed dark berry for years. They even found preserved remains of blackberries in the body of a Danish woman from 2,500 years ago! (2)

Blackberries vs. Black Raspberries 

Blackberries are often confused with black raspberries, which have a similar look and taste. Plus, they both belong to the Genus Rubus family. But they are actually two different berries! 

The big difference between the two is that when you pick raspberries, the stem remains on the plant. But with blackberries, the stem stays on the fruit. This gives a hollow look to the raspberry while blackberries retain their juicy core. (1,2)

5 Potential Health Benefits of Blackberries

Thanks to their high antioxidant, mineral, and vitamin content these fruits are a powerhouse for your health! Here are some of the potential health benefits of a serving of delicious blackberries:

Helps Boost Immunity

Thanks to the high vitamin C, K, and manganese content, blackberries could help support your immune system. (3) 

  • Vitamin C: Not only is Vitamin C an incredibly powerful antioxidant with a protective effect on the body but it's also directly involved in the production of white blood cells. And these cells are key to helping the body fight against germs and illness. (4)
  • Vitamin K: This vitamin handles the creation of several proteins that your body needs to support blood clotting and the formation of bones. In other words, it’s key to healthy bone tissue and healing. (5)
  • Manganese: This mineral supports your connective tissue and bones, protecting your cells from damage. It also helps with blood clotting and plays a pretty crucial role in your calcium absorption, carbohydrate metabolism, and blood sugar regulation. (6)

The health benefits of these vitamins and minerals help keep things running smoothly in the body. They also keep your energy levels high so you can maintain a healthier body and mind. 

Supports Better Digestion and Gut Health

The average American doesn’t get nearly enough fiber in their diet. This is a problem because fiber is crucial for keeping you feeling full and aiding in a healthy digestive system. 

Fiber helps keep things moving in the body, preventing uncomfortable problems like constipation and bloating. It also helps break up the bad cholesterol or LDL cholesterol in the body, helping manage your blood sugar levels. (3)

Luckily, blackberries offer a great source of fiber! One cup contains 8g of fiber, which helps add this crucial non-digestible carbohydrate to your diet. Blackberries are especially high in insoluble fiber, which helps break down food in the body and promotes more regular bowel movements. (2)

Contains Stress-Fighting Antioxidants

Blackberries are especially known for their abundance of antioxidants called polyphenols. These antioxidants can help you fight off free radicals and protect your cells from damage. One polyphenol, in particular, called anthocyanin, could also help protect your body from inflammation, which is the cause of a lot of different health problems. (3) 

What are free radicals? They’re chemicals in your body that form from internal and external stressors like exercise, metabolism, cigarette smoke, air pollution, and more. Free radicals cause oxidative stress or cell damage in the body, potentially leading to chronic diseases.

The body has its processes for defending itself against free radicals. However, a healthy diet of antioxidants and superfruits like blackberries can help your body defend itself.

Helps Build a Healthy Heart

Heart attacks, strokes, chest pain, and other heart issues are often a result of buildup in the arteries that block life-giving blood from flowing throughout your body. (3) Nutrients that help break up the build-up are crucial for supporting a healthier heart. And the anthocyanins in blackberries might be just the nutrient for the job. 

Many studies show that this antioxidant could help lower your unhealthy cholesterol levels while boosting your healthy cholesterol. And the mineral manganese also helps support healthy cholesterol levels and blood sugar regulation. This is what gives blackberries a good reputation for those looking to manage their insulin and blood levels. (2,3)

Improves Brain Function

According to one review of several studies, blackberries and other berry fruits could also help support your brain health! In the review, they cite several studies that indicate potential neurological benefits associated with berry fruits. 

Possible brain benefits include improved cognitive and motor function, better memory, attention, speech, and protection against other age-related brain issues. (7) This benefit could be thanks to the antioxidants like anthocyanin that may help lower brain-related inflammation. (3)

Can you eat blackberries every day?

Health experts recommend enjoying two servings of fruit daily, around 2 cups. (3) And if you love blackberries, they’re a great, healthy fruit option to enjoy every day.

Stick with the package they came in and make sure to avoid any airtight containers. Once in the fridge, blackberries usually last around two to three days.
