Raspberries are a delicious edible fruit that contains lots of vitamins, minerals, and many other nutrients. Raspberries are low in carbohydrates and calories and are a tasty and healthy addition to your diet. One ounce (28 g) of raspberries contains 7.3 mg of vitamin C which is about 12% of your recommended daily vitamin C intake.


Red raspberries are the most popular type of raspberry with many health benefits. Consuming raspberries has been linked to lowering blood pressure, losing weight, and boosting cognitive function. Black raspberries have nutrients that are excellent for promoting good heart health.

Raspberries can also be yellow or purple, depending on the species.

In this article, I will look at the amazing nutritional value of raspberries and how they can benefit your health.

What are Raspberries?

Raspberries are a small fruit that grows on the raspberry plant. Raspberry is from the Rubus genus and is cultivated in many countries around the world. The botanical name of red raspberries is Rubus idaeus and is sometimes referred to as the European raspberry.

Despite the name, raspberries aren’t truly classed as a berry. Raspberries are called aggregate fruits that are a collection of tiny “drupes”, each with a seed inside.

Doctors from WebMD say that red raspberries and raspberry leaf extracts have been used for centuries due to their medicinal properties. (1)

Red raspberries have a sweet but tart taste which gives them a unique flavor when compared to other fruits and berries. Raspberries are only slightly acidic, with some types of raspberries being sweeter than others.

Black Raspberry vs. Red Raspberry

Black raspberries are becoming very popular due to their health benefits. Black raspberries are sometimes mistaken for blackberries, however black raspberries, just like red raspberries, are hollow without a core. On the other hand, blackberries have a white core where the stem attaches to the fruit, and are not hollow.

Apart from the color, the main difference between black raspberries and red raspberries is the taste. Many people describe the taste of black raspberries as being less tart and slightly sweeter than red raspberries.

Black raspberries have compounds that can boost your cardiovascular health. Results of studies indicate that black raspberries can help lower cholesterol and reduce inflammation. (2)

Nutrition Facts of Raspberries

Raspberries are packed full of goodness that can help to boost your immunity, keep your heart healthy, and your digestive system working well.

According to the United States Department of Agriculture (USDA), 1 cup of raw raspberries (123 g) contains 64 calories, 14 g carbohydrates and 1.48 g protein.

One cup of raspberries (123 g) also contains 8 g fiber which is 33% of your recommended daily intake (RDI) of fiber! (3)

100 grams of raspberries have a low GI (glycemic index) of 2 with 42 g of carbs and 4 grams of sugar. (11)

Red, black, and other colored raspberries also contain large amounts of vitamin C. A serving of 100 g fresh raspberries contains 26 mg of vitamin C which is nearly half of your required vitamin C intake. Vitamin C is a powerful antioxidant that strengthens your immune system to help fight infections and prevent chronic diseases. (4)

Another of the great benefits of consuming raspberries is that raspberries contain xylitol. The Journal of Food Science reports that from all fruits and berries, raspberries contain that highest levels of xylitol. There are approximately 400 μg xylitol per 1 g of fresh raspberries. (10)

Xylitol is used as a natural sweetener because it is lower in calories than sugar. This means that raspberries are a good fruit to eat if you have diabetes, as they won’t cause a spike in blood glucose levels.

The nutritional content of raspberries also includes vitamins A, E, K, and some B-group vitamins. There are also trace amounts of lutein, zeaxanthin and B-carotene, all of which are important vitamins for healthy eyes and skin.

100 g of raw raspberries have 34 mcg manganese which is over 30% of your daily recommended intake. Raspberries also contain minerals that benefit your health such as potassium (4% RDI), magnesium (5% RDI), iron (4% RDI), and calcium (2% RDI). (3)

Antioxidants in raspberries

Raw raspberries also contain important antioxidants that benefit your health. Antioxidants are important to rid the body of free radicals that can contribute to chronic disease.

Red ripened raspberries have a total ORAC value of 5065, which makes raspberries one of the top fruit sources of antioxidants. Black raspberries have an even better ORAC value of 19,220. ORAC stands for oxygen radical absorbance capacity and is a way to measure the levels of antioxidants in foods. (9)

Research has found that raspberries contain various tannins that have health-promoting properties. The study found that various tannin compounds in raspberries combine to have an antioxidant effect. (5)

According to one scientific study into the nutritional benefits of red raspberries, they contain 10 flavonoids with antioxidant properties. Flavonoids are important bioactive compounds to help reduce the risk of chronic diseases like heart disease, cancer, and degenerative brain diseases. (8)

Health Benefits of Raspberries

Raspberry juice may prevent plaque buildup in your arteries

Drinking raspberry juice can also help prevent heart disease because it can reduce your risk of atherosclerosis.

Scientists found that polyphenolic compounds in raspberry juice prevent a buildup of plaque in the arteries. The research was conducted on animals and showed that consuming raspberry juice boosts levels of antioxidants and helps to lower triglyceride levels. (14) Doctors from the Mayo Clinic say that this is an important factor in keeping your heart healthy. (15)

It is a known fact that a diet rich in fresh fruits, raspberries, berries, and vegetables can help prevent heart disease. (12)

Black Raspberries are Good for Heart Health

Black raspberries contain even higher levels of antioxidants than red raspberries and can help improve your cardiovascular health.

One randomized placebo-controlled trial found that black raspberry extract helps to significantly lower blood pressure. Patients with pre-hypertension who took 321.5 mg of raspberry powder extract a day over an 8-week period experienced a significant drop in blood pressure. (24)

Another trial using black raspberry extract showed that it can reduce your overall risk of cardiovascular disease. (25)

Black raspberry can also improve your artery health because it reduces total cholesterol levels and inflammatory markers. (26)

Raspberries have Anti-inflammatory Properties

Regularly consuming red or black raspberries can help reduce inflammation in your body and may prevent certain diseases.

Raspberries May Improve Insulin Sensitivity in Diabetics

Raspberries are a good fruit to eat if you have diabetes because they are low in sugar and carbs. However, raspberries can also help to manage symptoms of diabetes due to their potential to alleviate insulin resistance.

Research published in 2018 on the nutritional health benefits of raspberries found that they can help manage type 2 diabetes. The antioxidant effect of raspberries helped to reduce certain inflammatory responses. This helped to improve insulin sensitivity and also help reduce obesity. The researchers concluded that raspberry has potential use as a dietary treatment for diabetes. (20)

The Journal of Agricultural and Food Chemistry reported that raspberry extracts can help to kill off human cancer cells. Lab tests have shown that extracts from black raspberries and red raspberries can prevent the growth of tumors in breast cancer, colon cancer, prostate cancer, and oral cancer. (21)

Other studies have shown that some varieties of raspberry extracts have the ability to stop cervical cancer cells from spreading. (22)

Some of the anticancer properties of raspberries are due to the flavonoid anthocyanin. This is a pigment that gives raspberries their color. Scientists found that this powerful antioxidant can help to inhibit cancer cell growth in lung cancer, gastric cancer, breast cancer, and colorectal cancer. (23)

Most of the research into the use of raspberry extracts to treat cancer has been carried out in laboratory settings. There is still much research to do on how raspberries can be used to treat cancerous growths in humans.

Raspberry Leaf Health Benefits

Raspberry leaf can help to improve your overall health and strengthen your immune system because of its high levels of antioxidants.

Dried leaves from the red raspberry plant are a rich source of tannins and ellagic acid. Research has also revealed that red raspberry leaves have more antioxidants than raspberry fruits. (27)

In Europe, raspberry leaf extract has been approved as an herbal medicinal remedy to relieve menstrual pain, treat mild cases of diarrhea, and reduce inflammation in the throat or mouth. (27)

Raspberry leaf has traditionally been used to help induce labor in pregnant women. A study published in the Journal of Midwifery and Women’s Health indicated that red raspberry leaf helps shorten the duration of labor and lowered the rate of forceps deliveries. The women who participated in the study consumed raspberry leaf tablets (2 × 1.2 g per day) from 32 weeks’ gestation until labor. (28)

Raspberry Ketones and Weight Loss

Raspberry ketones are a popular weight loss supplement because people claim they help to burn fat and increase metabolism.

You can get small amounts of ketones from raspberries by eating raw, fresh raspberries. However, it’s important to know that “raspberry ketone” supplements are in fact synthetically made. The Biotechnology Journal reports that extracting ketone from raspberries is very expensive. (29)

There is no scientific evidence that taking raspberry ketone supplements can help with weight loss. A trial from 2017 found that feeding mice raspberry ketones didn’t result in any weight loss. (30)

One trial did involve using a weight loss supplement to help overweight men lose weight. These supplements contained raspberry ketones, capsaicin, caffeine, ginger, and garlic. Even though some of the men experienced body weight loss, there is no evidence to suggest that this was due to raspberry ketones. (31)

How to Store Raspberries to Keep Them Fresh

It is important to store fresh raspberries properly to prevent spoilage. If possible, you should choose organically-grown raspberries that have the appropriate certifications. You should choose raspberry fruits that are firm and have a deep color.

To store raspberries properly so they retain their nutritional benefits, you should keep them in the refrigerator. This helps to prevent loss of vitamin C and other vitamins and minerals in fresh raspberries.

You can also stop raspberries from losing their nutrients by freezing them. To freeze raspberries to prevent them from deteriorating, you should first of all gently wash them to remove any dirt or impurities. Then pat dry with a paper towel. Place on a tray and put in your freezer until solid. Then transfer them to a freezer bag.

This way you will keep the shape of the raspberries and enjoy their nutritional value for many months throughout the year.

Other Healthy Berries

Other berries, such as blueberries, cranberries and blackberries are also true superfoods that have many medicinal properties:

1. They have anti-aging components that slow the aging process and help to prevent free radical damage in your body.

2. They are essential in preventing heart disease.

3. They have anti-cancer properties.

4. They may help in weight management: they have low sugar content, so they don’t add extra calories to the body. Their high fiber content helps to improve digestion and helps you feel fuller for a longer time too.

5. Berries are rich in healthy nutrients, fiber, organic acids and are full of antioxidants. This combination makes them ideal for better digestive health and to get rid of various harmful toxins.

Although it may not be easy to get fresh berries, you’ll be happy to know that even drying or freezing them still offers many health benefits.

So if so far you didn’t develop the habit of consuming berries of all kinds and types, then this is the time to start. Their health benefits are just something that we should not ignore.

Each berry has its own uniqueness which you can read about in my e-book The Healing Berry Guide where you can find more information about the healing powers of berries.
