Blackberries are purple-hued fruits packed with health-supporting benefits like vitamins and minerals, and antioxidants. Including blackberries in your diet reduces your risk of several health conditions, including heart disease. In addition to providing fiber, blackberries are one of the richest sources of anthocyanin pigments, compounds that have powerful cellular-protective properties.

1. Good Source of Fiber

One of the main health benefits of blackberries is that they’re packed with nutrients known to support health, such as fiber, vitamins, and minerals.

Just one cup of blackberries contains nearly 8 grams (g) of fiber, which covers 28.5% of the Daily Value (DV) for this important nutrient. Following a high-fiber diet can benefit your gut health by fueling the growth of beneficial bacteria in your large intestines, supporting a healthy gut barrier, and encouraging regular and comfortable bowel movements.

Eating a high-fiber diet may also help protect against digestive conditions such as colon cancer and diverticulitis.

2. Provides Many Vitamins and Minerals

Blackberries also provide an array of vitamins and minerals, including vitamin C, folate, manganese, vitamin K, and magnesium, all of which play essential roles in health.

For example, folate is a B vitamin necessary for the maturation of red blood cells, cellular division, and other critical processes. Folate needs increase by 50% during pregnancy due to this vitamin’s role in fetal growth and development. For this reason, blackberries make an excellent fruit choice during pregnancy.

3. May Reduce Inflammation

Blackberries contain plant compounds that help protect cells against oxidative damage by reducing reactive compounds called free radicals and inhibiting inflammation. They are rich in phenolic compounds, such as ellagic acid, quercetin, and anthocyanin pigments, which give blackberries their saturated purple color.

Regularly eating anthocyanin-rich foods like blackberries may lower your risk of developing diseases like heart disease and neurodegenerative diseases that are associated with oxidative stress, a condition that occurs when harmful compounds such as free radicals overwhelm the body’s antioxidant defenses.

A 2020 study evaluated the total phenolic and anthocyanin contents and the total antioxidant activity of six different berries: blackcurrant, red raspberry, redcurrant, blackberry, gooseberry, and jostaberry. It was found that the blackberries had the highest antioxidant and anthocyanin levels out of all of the included berries.

Blackberries also inhibit certain pro-inflammatory pathways in the body, like the nuclear factor-κB (NF-κB) signaling pathway, and decrease levels of inflammatory proteins. Because of their anti-inflammatory effects, blackberries may be helpful for those with inflammatory conditions such as rheumatoid arthritis and inflammatory bowel disease (IBD).

4. May Protect Against Heart Disease

Berries are a concentrated source of heart-protective compounds, such as fiber and anthocyanins, and studies show that regularly eating berries, like blackberries, is an effective way to support heart health.

Research shows that consuming blackberry juice with pulp may reduce compounds associated with increased heart disease risk, including apolipoprotein B and the inflammatory marker high-sensitivity C-reactive protein, compared to a control group. It also may increase levels of heart-protective HDL cholesterol and apolipoprotein A, a protein that helps HDL remove bad cholesterol from the bloodstream.

A 2021 review of 59 studies found that high dietary intake of anthocyanin-rich foods, including berries, was related to a 17% reduced risk of coronary heart disease, a 27% reduced risk of total heart disease incidence, and a 9% lower risk of total heart disease-related death.

Regular fruit intake, including berry consumption, has also been associated with a lower risk of several other diseases, such as certain cancers and type 2 diabetes.

Nutritional Facts of Blackberries

Blackberries are low in calories yet rich in fiber, vitamins, and minerals. Blackberries contain a variety of nutrients but are a very good source of fiber, vitamin C, vitamin K, and manganese.

Here’s the nutrition breakdown for a one-cup serving of raw blackberries:

  • Calories: 61.9

  • Carbohydrates: 13.8 g

  • Protein: 2 g

  • Fat: 0.7 g

  • Fiber: 7.63 g

  • Sugars: 7 g

  • Folate: 36 mcg (9% DV)

  • Pantothenic acid: 0.397 mg (8% DV)

  • Vitamin C: 30.2 mg (34% DV)

  • Vitamin K: 28.5 mcg (24% DV)

  • Magnesium: 28.8 mg (7% DV)

  • Manganese: 0.93 mg (40% DV)

Fiber is important for digestion and heart health and helps you feel satisfied after meals.

It’s recommended that adult women and men under the age of 50 consume 25 g and 38 g of fiber per day, respectively. Unfortunately, research shows that the average American only consumes about 15 g of fiber daily, which is well below the recommended intake.

Blackberries are also rich in vitamin C, a nutrient with powerful antioxidant properties that’s essential for immune function, and vitamin K, which plays important roles in skeletal health and blood clotting.

Additionally, these berries are a good source of the mineral manganese, a nutrient that’s involved in energy metabolism and immune and nervous system function. They also provide smaller amounts of folate, magnesium, and some B vitamins.

Risks

Blackberries are a nutritious food that's safe for most people. However, it's possible to have a blackberry allergy.

Blackberries are also high in compounds called salicylates, a group of chemicals derived from salicylic acid. Some people are sensitive to these compounds and may develop symptoms, such as a stuffy nose, abdominal pain, and hives, after consuming salicylate-rich foods.

Salicylate sensitivity is more common in people with certain medical conditions, including asthma.

Tips for Consuming Blackberries

Blackberries have a sweet taste and can be enjoyed fresh or cooked. Frozen blackberries make a convenient and cost-effective choice as they can be kept in the freezer for long-term storage and added to recipes like smoothies and baked goods.

Here are a few ways to incorporate blackberries into your diet:

  • Add blackberries to savory salads

  • Add fresh blackberries to yogurt, oatmeal, and chia pudding
