Blackberry

Summary

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.

Introduction

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.

Nutrition

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.

Calories

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.

What Does 43 Calories or 100 Grams of Blackberry Look Like?

43 Calories or 100 Grams of Blackberry

The photo below will help you visualize what 100 grams of blackberries look like. We measured 22 medium-sized blackberries, which comprised 100 grams (43 calories), meaning each blackberry is approximately 4.55 grams or 1.95 calories. These numbers can vary depending on the blackberries' size, ripeness, and weight. Unripe blackberries have lower sugar levels and fewer calories than fully ripe ones.

Protein

One average serving (144 grams) of blackberries provides 2g of protein.

Carbohydrates

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 than oranges, which are well 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 to prevent constipation.

Vitamins

Blackberries can be an excellent vitamin-rich snack to add to any diet. The predominant vitamins found in blackberries are vitamin C and vitamin K. 

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%.

Blackberry can be a good source of tocopherols or vitamin E and folate or vitamin B9 as well. It contains vitamins B1 (thiamin), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), and B6 (pyridoxine) in smaller amounts.

Blackberries lack vitamin D and vitamin B12 entirely.

Minerals

Blackberries are great sources of manganese and copper, falling in the top 35% of foods as a source of 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.

Oxalates

Oxalates are compounds found in plants, which, when consumed, may bind to calcium, increasing the risk of kidney stone formation

The research behind the oxalate content in blackberries is quite contradictory, with some listing them next to blueberries as low-oxalate foods. A study by Han et al. states that blackberries contain 19mg of oxalates per 100-gram serving, which can be considered low to moderate levels of oxalates (8). 

Phytochemicals

Blackberries are abundant in health-beneficial plant nutrients, which provide antioxidant and anti-inflammatory properties and help fight various diseases, including cancer and heart disease (13).

Terpenoids

A recent study by Gil-Martinez et al. states that terpenoids and phenolic compounds are the major phytochemicals found in blackberries (12). Not only do the authors quantify the terpenoid content in blackberries, but they also discuss that terpenoids have been demonstrated to be effective antitumor, antibacterial, and antiviral agents. 

Anthocyanins

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 that help 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).

It is interesting to note that in a study by Avila-Nava et al., the authors compared over 100 different foods for their oxalate content and antioxidant activity and observed that blackberries and strawberries exhibited the highest antioxidant activity, which was attributed to their polyphenol content (9).

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

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).

Acidity

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.

FODMAPS

Monash University has established the low-fodmap diet to help patients struggling with various gastric disturbances (including IBS) identify their triggers and manage their symptoms (10). 

Blackberries are especially high in polyols, which makes them unsuitable for the low-fodmap diet, although portion size and ripeness play a big role as well (11). 

Nutritional Comparison of Wild and Cultivated Blackberries 

In a study where domesticated and wild blackberries from Mexico were compared for their anthocyanin contents, it was found that wild blackberries had much higher levels of anthocyanins than commercial or cultivated varieties, hinting that depending on the type of blackberry you eat, the health benefits may vary (14).

Another study used three different methods to compare the antioxidant activity of wild and cultivated blackberries and found that the wild blackberries showed the highest antioxidant activity in all measurements (15). Moreover, the total phenolic content in wild blackberries was much higher compared to cultivated blackberries.
Hence, although wild and cultivated blackberries are rich in various nutrients essential for health, wild blackberries are richer in various phytochemicals and, thus, in antioxidant activity.

Comparison to Similar Foods

Compared 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.
