Vegan Diet

Blackberries and raspberries are highly recommended for a vegan diet. Although not rich in proteins, they provide good amounts of antioxidants and flavor to the foods or fruit bowls they associate with.

Keto

Blackberries and raspberries are approved to be eaten in a keto diet. They are mostly water and are recommended in shakes and fruit bowls. They also provide good amounts of fiber, promoting good gastrointestinal health and other benefits.

Cardiovascular Health

Section reviewed by cardiologist Astghik Grigoryan

While limited direct research exists on the impact of raspberries and blackberries on blood pressure, their nutritional composition indicates potential benefits for cardiovascular health (2, 3).

Both raspberries and blackberries are good sources of potassium, a mineral that plays a key role in regulating blood pressure. 

Additionally, they are a good source of dietary fiber, linked to regulating cholesterol levels and preventing atherosclerosis.

Both berries are rich in antioxidants, such as anthocyanins, flavonoids, and ellagic acid, which may help reduce cardiovascular risk (4, 5).

Diabetes

Blackberries are associated with increased insulin sensitivity in people at high risk of developing type 2 diabetes. Thus, a decreased risk of developing type 2 diabetes. (6)

In contrast, raspberries are directly associated with decreased risks of metabolic syndrome, which means decreased risks of developing type 2 diabetes. (5)

Inflammation

Due to the antioxidants present in blackberries, anthocyanins, and phenolic compounds, blackberries overall reduce oxidative stress and inflammation in the body. (7)

Raspberries are rich in flavonoids and polyphenols, which have an anti-inflammatory role.

In blackberry and raspberry, the anti-inflammatory characteristic of both is significant because of the reduction of inflammation and oxidative stress, which lead to reducing risks of developing cancer. (5)

Cancer

Blackberries have anti-tumor characteristics that induce cancer cell death by its apoptotic factors. In addition, blackberries are rich in lignan, which has a characteristic of decreasing the risks of breast cancer in postmenopausal women. (8)

On the other hand, raspberries have shown anti-carcinogenic properties related to colon cancer. (9)

Effects on the Brain

Blackberries have a positive influence on short-term memory and cognitive functioning. (10)

On the other hand, Raspberries reduce the risks of developing Alzheimer’s disease in people who are at high risk of developing Alzheimer’s disease and are obese. (11)

Post-intestinal Surgery

Doctors indicate that the patient should follow a low-fiber diet in post-intestinal surgeries. Blackberries and raspberries have to be excluded from the diet. (12)

Raspberry Ketones

Some supplements are sold as raspberry ketones, which they claim to have weight loss properties. However, evidence-based research has shown that this does not affect fatty tissues and weight loss. The weight loss that took place was due to the high amounts of caffeine in the supplement. (13)

Taste and Appearance

Although raspberry and blackberry have a similar appearance, anyone can easily distinguish them by color. Raspberries are deep pink or red when fully ripe, while ripe blackberry fruits have deep purple or black coloring. Besides, raspberries have velvety skin covered with tiny hairs, while the skin of blackberries is usually smoother. 

Blackberries have a slightly tart and sweet flavor and usually have an earthy flavored aftertaste. They are juicy, and the riper they become, the sweeter they become.

On the other hand, raspberry is less tart than blackberry. In addition, raspberry is less juicy than blackberry.

In conclusion, although blackberries are often called black raspberries, they are different fruits.
