Blackberries are an excellent source of insoluble dietary fiber, vitamin C, vitamin K, manganese, and copper. Additionally, these berries are rich in antioxidants, such as anthocyanins, giving them various health-beneficial qualities.


Blackberries are known as healthy snacks and delicious additions to fruit salads, yogurts, pastries, and more. But what exactly gives these berries their favorable qualities? In this article, we will discuss the nutritional content of blackberries in detail to see what sets this fruit apart from others.


The nutritional information below will be presented mainly for raw blackberries. However, key differences will also be mentioned between raw and frozen, unsweetened blackberries (1).

Like most other fruits, blackberries are not very dense in nutrients, consisting of 89% water and 11% macro and micronutrients.

However, frozen blackberries lose water and contain 82% water and 18% nutrients.

The average serving size of blackberries per person is one cup or 144g.

Blackberries are low in calories, providing only 43kcal per 100g serving. Consequently, one average serving size of blackberries contains 62 calories.

Frozen blackberries, being denser in nutrients, provide 21 additional calories per every 100g.


One average serving of blackberries provides 2g of protein.


Most of the macronutrient content of blackberries is made up of carbohydrates. In every 100g serving, about 10g of carbohydrates can be found. Overall, the carbohydrates of blackberries consist of 48% net carbs and 52% dietary fiber.

Dietary Fiber

Blackberries provide 5.3g of dietary fiber per every 100g serving. This puts blackberries in the top 17% of foods as a source of fiber and covers 21% of the daily fiber needs.

Blackberries are 2.2 times richer in dietary fiber compared to oranges, known for their high fiber content.

The dietary fiber content of blackberries consists predominantly, about 92 to 97%, of insoluble fiber (2, 3). Insoluble fiber lets food pass through the digestive tract quicker, helping with constipation.

Unsweetened frozen blackberries, being nutritionally denser, can contain 5g more sugars per 100g serving.

The total sugar content, including glucose and fructose, can notably increase as the fruit matures (4).

Blackberries can be an excellent vitamin-rich snack to add to any diet.

Blackberries fall in the top 19% of foods as a source of vitamin C. A 100g serving of these berries covers 23% of the daily need for this vitamin. The same serving can also provide 17% of the daily required amount of vitamin K.

These berries are in the top 33% of foods as a source of vitamin A. However, as the daily vitamin A requirement is relatively high, a 100g serving covers only 4% of it.

Blackberry can be a good source of tocopherols or vitamin E and folate or vitamin B9 as well. It contains vitamins B1, B2, B3, B5, and B6 in smaller amounts.

Blackberries lack vitamin D and vitamin B12 entirely.

Blackberries are a wonderful source of manganese and copper, falling in the top 35% of foods as a source of both these minerals. A 100g of blackberries covers 28% and 18% of the daily needed values of manganese and copper, respectively.

These berries can also be a good source of iron. Other minerals found in blackberries in moderate amounts include magnesium, potassium, and zinc.

Blackberries are very low in sodium, containing only 1mg in a 100g serving.

Blackberries are abundant in health-beneficial plant nutrients.


The most notable of these phytochemicals may be the phenolic pigment anthocyanin. This compound is what gives blackberries their distinct dark coloring. The darker the berry, the richer it is in anthocyanins.

Anthocyanins, like other flavonoids, are strong antioxidants, helping prevent cell damage by reducing the formation of harmful reactive oxygen species.

The anthocyanin content of blackberries increases as the fruit matures (5).

Phenolic Compounds

Other antioxidant phenolic compounds found in blackberries are gallic acid, hydroxybenzoic acid, catechin, epicatechin, caffeic acid, ferulic acid, ellagic acid, and quercetin.

The levels of gallic acid, hydroxybenzoic acid, epicatechin, and ellagic acid increase with maturation, while catechin, caffeic acid, and quercetin levels decrease (5).

Malic Acid

The primary organic acid found in blackberries is malic acid. This compound is responsible for the tart taste of blackberries. However, malic acid also stabilizes the anthocyanins and extends the shelf life of these berries (4).

The malic acid content of blackberries decreases as they mature.


Lignans are phytoestrogen compounds found in blackberries that can play an important role in preventing certain types of breast cancer and cardiovascular diseases (4).

Glycemic Index

An exact number has not yet been measured for the glycemic index of blackberries. However, this number is assumed to fall in the low category.

Blackberry extract has been researched to have hypoglycemic and antidiabetic qualities, decreasing blood glucose levels and improving insulin sensitivity in diabetic rats (6, 7).


Blackberries are acidic. However, the pH value of blackberries gets less acidic as they mature, going from 2.3 to 2.9 (5).

Another way of looking at the acidity of foods is the potential renal load value or the PRAL, which measures how much acid or base the given food produces inside the body.

Blackberries have a PRAL value of -2.8, making them alkaline-forming.

Comparison to Similar Foods

In comparison to mulberries, blackberries are higher in fiber, vitamin A, vitamin E, vitamin K, copper, and zinc. In contrast, mulberries are richer in sugars, vitamin C, vitamin B2, iron, calcium, potassium, and phosphorus.

Compared to blueberries, blackberries contain more vitamin C and fewer carbohydrates, including sugars. At the same time, blueberries are richer in vitamins B1, B5, and B6.

Blackberries contain more fiber, manganese, copper, vitamins A, E, and K than raspberries. Raspberries, however, have higher amounts of magnesium, vitamin C, and folate.

Health checks

Low in Cholesterol
 ⓘ Dietary cholesterol is not associated with an increased risk of coronary heart disease in healthy individuals. However, dietary cholesterol is common in foods that are high in harmful saturated fats.
No Trans Fats
 ⓘ Trans fat consumption increases the risk of cardiovascular disease and mortality by negatively affecting blood lipid levels.
Low in Saturated Fats
 ⓘ Saturated fat intake can raise total cholesterol and LDL (low-density lipoprotein) levels, leading to an increased risk of atherosclerosis. Dietary guidelines recommend limiting saturated fats to under 10% of calories a day.
Low in Sodium
 ⓘ Increased sodium consumption leads to elevated blood pressure.
Low in Sugars
 ⓘ While the consumption of moderate amounts of added sugars is not detrimental to health, an excessive intake can increase the risk of obesity, and therefore, diabetes.
