Raspberries are berries with countless health advantages. Here’s why it’s healthy to incorporate them in your regular eating regimen.
The consumption of vegetables and fruit has all the time been a part of healthy diets, since they protect against certain diseases generated by oxidative stress. Raspberries (Rubus spp.) are an example of one of these food, as they supply antioxidants. In reality, there are numerous advantages of raspberries.
Raspberries, along with being popular in sensory terms, are also considered functional foods or nutraceuticals. They contain bioactive compounds, similar to anthocyanins, which have proven health advantages,
The raspberry of any variety is the fruit of a shrub that belongs to the Rosaceae family. It normally grows in European forests, where it’s native. It seems to have originated in Greece and from there passed from other countries to North America.
Probably the most common varieties are red(Rubus idaeus), typical of Europe, and red and black in North America, similar to black raspberry(Rubus occidentalis), wild raspberry(Rubus strigosus), and purple raspberry (Rubus neglectus).
Its shape is round or conical. The skin is velvety and covered with high quality hairs. It’s a fruit that consists of many berries grouped in miniature, every one containing a single seed.

The next is a listing of nutrients in a traditional serving (1 cup or 144 grams of raw raspberries) of any variety:
- Energy: 75 calories.
- Carbohydrates: 18 grams.
- Fiber: 7.6 grams.
- Potassium: 282 milligrams.
- Vitamin C: 30 milligrams.
In response to the indicated values, raspberries could be included in weight reduction diets, since a traditional portion only provides 75 calories. The energy in raspberries comes from fructose and glucose, that are absorbed in a short time.
The potassium value is comparable to that of lemon juice, sliced mango, and melon pulp. Potassium helps with muscle contraction and heart rate.
Raspberries have a fiber content above other fruits. They’re consumed whole, which serves to reap the benefits of their soluble and insoluble fiber and stop constipation.
Vitamin C is present in moderate values, so it’s really useful to eat it fresh to make one of the best use of it. If you happen to are going to arrange raspberry juice, do it quickly in order that vitamin C doesn’t oxidize.
Bioactive components in raspberries
Several experts agree that raspberries, blackberries, and berries usually contain several forms of antioxidant polyphenols, similar to phenolic acids, flavonoids, and anthocyanins, and others similar to resveratrol and ellagic acid. Because of this, Clark and Finn recommend red fruits throughout the health improvement program.
Other researchers published that anthocyanin values in raspberries and other berries could be as high as 223 milligrams per 100 grams of fruit. Polyphenols range from 657 to 2611 milligrams in 100 grams of dried fruit.
Vitamin C was found to range from 14 to 103 milligrams per 100 grams of fresh raspberries. These values support the high antioxidant capability.
It’s clear that the majority of the advantages of raspberries are attributable to the presence of antioxidants that protect the body when consumed. But let’s take a look at a number of more issues.
1. They improve some intestinal problems
A eating regimen low in fiber is related to intestinal problems similar to constipation and bloating. As well as, a BMJ article published that when fiber shouldn’t be enough within the eating regimen, it might increase the chance of heart disease.
One cup of fresh raspberries, despite their small size, can provide as much as 8 grams of fiber. Raspberries are the very best fiber berry in comparison with others, similar to blackberries, strawberries, and blueberries.
If you eat the required amount of fiber you lower cholesterol, control blood sugar, promote bowel movement, and keep you feeling full. Some forms of fiber act as food for intestinal bacteria.
2. They’ll fight oxidative stress
Free radicals are molecules which might be formed from biological reactions within the body. They’re very reactive, in order that they oxidize and damage whatever is around them. This effect results in degenerative diseases and aging. To live a healthier life, a balance between the formation of free radicals and the antioxidants that may neutralize them is mandatory.
The darker the raspberry, the greater the range of anthocyanins and cyanidins with antioxidant capability. An antioxidant value 3.5 times higher than vitamin E is reported. Not to say the vitamin C content, which also has these properties.
The journal Nutrition Research reported that 300 grams (10 ounces) of berries are capable of protect DNA against free radical damage. Likewise, one other study revealed that eating 1/2 kilo of berry pulp day by day for a month reduces a prooxidant marker by 38%.
3. Decrease the chance of heart disease
When LDL or bad cholesterol values rise within the blood, it becomes a risk factor for the guts. Phenolic compounds in raspberries and other berries may protect the guts by inhibiting LDL oxidation.
Furthermore, it seems that anthocyanins suppress a protein generally known as MCP-1. This protein induces the formation of lipid plaques in arterial partitions.
4. They prevent neurodegenerative pathologies
Eating some delicious and juicy raspberries of various colours can improve brain health and help prevent the dearth of memory, common during aging. From the Human Nutrition Research Center on Aging, it was disseminated that antioxidants in berries, similar to raspberries, can prevent disruption in brain cell communication.
As well as, these fruits also help reduce brain inflammation that’s triggered by motor problems typical of aging and cognitive functions. A study in rats revealed that anthocyanins are useful in stopping Alzheimer’s disease.
5. They might improve insulin and blood sugar levels
Diets with a high glycemic response could also be related to an increased risk of obesity and sort 2 diabetes. Nonetheless, polyphenols may improve these responses and maintain blood sugar control.
The British Journal of Nutrition found that by eating raspberries and other berries with bread, participants improved insulin response. In obese individuals with insulin resistance tests have also been conducted. For six weeks they drank a purple berry smoothie 2 times a day. An improvement in insulin sensitivity was found.
6. They’re anti-inflammatory
Inflammation is an indication of the body’s defense against infection or injury. Fortunately, berries have anti-inflammatory properties. Chronic inflammation is a precursor to diabetes, obesity, and heart disease.
Some scholars claim that polyphenolic compounds, especially anthocyanins, have anti-inflammatory activity in animals and humans. This anti-inflammatory power of berries is effective each in individuals with normal weight and in those with obesity and obese. That is shown by a study.
7. They may very well be useful for the skin
Free radicals are likely to cause skin damage that accelerates aging. Nonetheless, specialists say that raspberries help reduce wrinkles.
Laboratory and animal tests indicate that the ellagic acid within the berries is the major antioxidant for the skin. It acts as a blocker of the enzymes that break down collagen.
Do you realize what collagen is? It’s a protein that offers structure to the skin and allows it to stretch and stay firm. If collagen is broken, then wrinkles appear.

8. Protect against cancer
Epidemiological evidence suggests that greater than 20% of cancer cases could be prevented with a eating regimen containing 400 to 800 grams of varied vegetables and fruits per day. Phytochemicals in berries, similar to raspberries, can modulate cancer initiation, promotion, and progression.
Some cancer researchers have worked on anthocyanins, resveratrol, and ellagic acid. They found that these phytochemicals induce antioxidation, cleansing, cell death, and antiproliferation of malignant cells in experimental animals.
Despite these results, the science continues to be lacking concrete results.
Some animal trials can’t be safely extrapolated to humans and others conducted on patients could also be contradictory.
Possible contraindications of raspberries
Although raspberries are delicious, nutritious, and useful, some precautions needs to be taken when consuming them, similar to the next:
- Red berries appear on the list of allergenic foods.
- They’re forbidden in cases of duodenal and stomach ulcers, gastritis, nasal polyps, nephritis, gout, asthma, and polyarthritis.
- They shouldn’t be a part of the eating regimen of people that are likely to form clots or take anticoagulants.
- Pregnant women can’t eat greater than 3 raspberries a day, as they may cause allergies.
Raspberries needs to be a part of healthy eating regimen programs. After all, combined with other vegetables and fruits.
A eating regimen with fresh raspberries, frozen, in ice cream, or with cream, shakes, and smoothies, amongst other preparations, will allow a healthier life through its antioxidants and anti-inflammatories.
