Today I would like to talk to you about the properties and health benefits of raspberries. Raspberries are members of the Rubus subgenus and come in a variety of colors: red, black, yellow and even a hybrid purple variety that is currently gaining a great deal of popularity. But color isn’t really that important when it comes to these forest fruits. What makes them a great addition to any diet is their nutritional profile, especially their vitamin C, manganese, iron and copper content and the fact that they are a source of potent antioxidants.

What should interest us next is whether or not they are organic. Numerous scientific studies have shown that organic raspberries may contain up to 4 times more antioxidants than most of the fruits readily available on the market. Fruits you may typically find at the supermarket may actually contain several times more pesticides and other hazardous chemicals than they should, posing serious risks to our health in the long-term, whereas raspberries are often safer choices thanks to the hardiness of the raspberry bush and the fact that it is a prolific producer of fruit.

What do raspberries look like?

Raspberries are small compound fruit, meaning what we know to be an individual fruit is actually made up of several others. Each fruit looks as if tiny, plump globes of fruit stick to each other to form one larger fruit. Also, each of the individual plump globes contains extremely small, edible seeds with incredibly fine hairs. If you remove the tender, green stems off of a raspberry fruit, you will notice it has a basket shape and is hollow on the inside. Depending on the variety, fruit may be smaller or larger, but typically no bigger than a fingertip. Also, raspberries can be red, yellow, purple or blue-black colored.

What do raspberries taste like?

Raspberries are a moderately sweet fruit, pleasantly acidity, with delicate forest fruit flavor notes. Red varieties have a balanced ratio of sweet and tart, but are overall quite sweet, assuming they are perfectly ripe and have enjoyed optimal growing conditions. Generally speaking, the more water and sunlight the plant receives during its fruiting period, the plumper, juicier and more flavorful the fruit.

There are pink and red raspberries, yellow raspberries, black raspberries and purple raspberries, and each tastes different.

Vs red, yellow raspberries develop a considerably sweeter taste when ripe. The yellow variety has a more straightforward sweet taste, with honey flavors and little to no acidity. Yellow raspberries are much more flavorful compared to red and often times preferred over red due to both their color and taste.

Another variety, black raspberries, combines the taste of red raspberries and blackberries into a flavorful fruit with a complex, moderately sweet and tart taste with unique flavor notes. As for purple raspberries, they taste like a mix of red and black raspberries, but slightly sweeter and less acidic, with deep fruity flavors.

Yellow raspberries are, in fact, a discolored variety of raspberry. The gene for the color red is inactivated in yellow raspberries.

Raspberries are highly perishable: once purchased or harvested from the plant, the fruit have to be consumed within about two days, assuming they are already perfectly ripe at harvest time. Raspberries should be kept in a cool place until ready to be eaten. If refrigerated, they are best kept at a temperature of around 2-4°C for no more than two days. They are also the perfect choice for any meal and not even the pickiest child will say no to a delicious raspberry and banana smoothie.

Antioxidants in raspberries

Raspberries are famous for their anticancer properties owed to high levels of phytochemicals with strong antioxidant and anti-inflammatory effects as well as anti-proliferative and anti-tumor activities. More specifically, antioxidant phytochemicals in raspberries scavenge harmful free radical molecules and protect cells against associated oxidative stress, preventing, limiting and repairing free radical damage. Antioxidants in raspberries further reduce inflammation brought on by cell damage caused by free radicals.

Even more, select phytochemicals in the fruit have been found to act on cancer cells and reduce the speed at which they reproduce, slowing down tumor growth and the rate of cancer spread. Organic raspberries in particular will have significantly higher levels of beneficial phytochemicals, natural compounds with anticarcinogenic and antitumor action. The health benefits they provide are unparalleled.

The pigments that give raspberries their color have scientifically proven anti-inflammatory, antioxidant and anticancer properties.

Anthocyanins, the pigments that give raspberries and many other fruit their red, purple and blue-black colors, exert strong antioxidant effects, have an anti-inflammatory action and scientifically proven anticancer properties, including anti-carcinogenic, apoptosis-inducing and anti-proliferative activities.

Ellagitannins in raspberries have anticancer and antiaging effects, according to studies.

Moreover, studies show a tannin in the fruit called ellagitannin can help reduce the number of cancer cells by sending specific signals to cancer cells that induce apoptosis, a cycle of programmed cell death. Ellagitannin compounds in raspberries have also exhibited anti-aging benefits, according to animal studies.

In the case of damaged cells that are not yet cancerous, but have the potential to become so, phytochemicals in the fruit trigger a process that prevents abnormal cell proliferation that could prevent tumor growth altogether. The wide range of natural antioxidants and anti-inflammatory compounds found in raspberries is truly remarkable, especially when very few fruits can provide them in such quantities.

  • List of antioxidants in raspberries

  • anthocyanins, cyanidins, pelargonidin, delphinidin, malvidins, flavonols (quercitin), kaempferol, catechin, glycoside, flavonoids (tiliroside), tannins (ellagitannins – sanguiin; gallotannins; proanthocyanidins), hydroxybenzoic acid, ellagic acid, lambertianin C, vanilic acid, gallic acid, chlorogenic acid, hydrxycinnamic acids (caffeic acid; coumaric acid; ferulic acid), stilbenes and resveratrol

Antioxidants are compounds occurring naturally in food that scavenge harmful free radical molecules that damage cells and regulate the activity of enzymes that have the potential to trigger inflammation. In view of such health effects, it has been theorized that eating raspberries regularly can reduce the risk of chronic diseases associated with oxidative stress and chronic inflammation such as: obesity, type 2 diabetes, hypertension, atherosclerosis, degenerative diseases of the nervous system, cancer and more.
