The first record of the fruit’s domestication dates back to the writings of Roman agriculturist Palladius, who lived in the 4th century. 
It is thought that the Romans were responsible for spreading the fruit’s cultivation throughout Europe. 
In Medieval Europe, the uses of wild raspberries included practical purposes and sometimes healing.
Their juices were used to make paint and dyes. 
Yet only the wealthy enjoyed them as a juicy delicacy.
British King, Edward I is considered to be the first person to encourage cultivation of the fruit in the 14th century. 
By the turn of the 18th century, raspberry bushes were thriving in gardens all over Britain and the rest of Europe. 
By this time, cooks throughout the Western world were developing recipes for sweets, jams and raspberry wine and vinegar. 
What are Raspberry Ketones?
Raspberries contain raspberry ketones; a natural phenolic compound. It’s also found in minuscule amounts in other fruits like kiwi, cranberries, and blackberries. 
Raspberry ketone, like those found in BioActive Raspberry Ketones, is the substance responsible for the fragrant smell of raspberries.
Throughout the ages raspberries have come to symbolize different things through myth and folklore.
In Pagan times it was thought that the juice of red raspberries represented the life blood of mythical creatures. 
Both English and Native American Cherokee women believed that drinking raspberry tea would ease the pain of child labor. 
According to the laws of Alchemy, raspberries were supposed to induce stamina and vigor as well as acting as a potent blood tonic. 
In dreams raspberries were believed to be related to matters of the heart: plump, ripe berries symbolizing happiness and good fortune: eating them meant good health. 
According to the Victorian language of flowers, raspberry flowers are a symbol of kindheartedness. 
Bottom Line: Raspberry ketones help the body burn fat by helping to break down fat at the cellular level. In addition to helping the body burn fat; the compound increases the production of adiponectin; a hormone assists in the regulation of metabolism, an important factor in weight loss.

Are Raspberries Good for You?
These plump red berries are packed with nutrients. 
The leaves and fruit of raspberries are rich in phytochemicals, such as anthocyanins, ferulic acid, quercetin, and ellagic acid. 
These are substances that benefit your immune system, skin, joints and circulation. 
Raspberries are also rich in anti-oxidants. 
Oxygen is critical for normal bodily functions like respiration and regulating the immune system, but it also has a dark side that can cause damage to your body’s cells and tissues. 
The root causes of this “oxidative stress” are oxygen-containing molecules known as free radicals. 
Bottom Line: Free radicals can cause damage to DNA, proteins and cell membranes by stealing their electrons. 
Benefits of Raspberries
Antioxidants are chemicals which have the ability to reduce or prevent oxidative stress.
Your body makes them to counteract the adverse effects of free radicals. 
You can also obtain them from dietary sources such as raspberries. 
As well as phytonutrients and antioxidants, raspberries are also rich in vitamins and minerals. 
The calories in raspberries is 52kcal and the carbohydrates in raspberries is 12g. 
Just 100g of the fruit will provide you with:
- Vitamin C: 43% Daily Recommended Intake (DRI)
- Manganese: 41% DRI
- Fiber: 32% DRI
- Copper: 12% DRI
- Vitamin K: 11% DRI
- Pantothenic acid: 8%
- DRI Biotin: 8% DRI
- Vitamin E: 7% DRI
- Magnesium: 7% DRI
- Omega-3 fats: 6% DRI
- Potassium 5% DRI
When Dr. Oz announced to the world that raspberry ketones benefits included weight loss, everyone listened. What we do know is there are raspberry ketone benefits like:
The ellagic acid in raspberries have powerful anti-inflammatory properties. 
This means they are beneficial for conditions such as Crohn’s disease.
It can also help reduce high cholesterol, lower the risk of prostate cancer and heal gastric ulcers. 
Regulating fat and blood sugar
One of the flavonoids in red raspberries, known as a glycosidic flavonoid, has been shown to activate a hormone that is produced in fat cells. 
Insufficient amounts of the hormone, known as adiponectin, are produced in people suffering from obesity or type 2 diabetes. 
By triggering its production, raspberries can help to rebalance blood sugar and blood fat in individuals with type 2 diabetes. 
Raspberries can also help people with type 2 diabetes avoid postprandial hyperglycemia, which occurs when sugar levels spike following a meal. 
A combination of chronic inflammation and severe oxidative stress can culminate in the development of cancer cells. 
Because raspberries provide and abundant supply of antioxidants, they can reduce oxidative stress and reduce the risk of cancer in a variety of human tissues including the breast, colon, cervix, prostate and esophagus. 
Raspberries’ phytonutrients may also be able to reduce cancer cell proliferation by transmitting signals to the tumor to trigger cell death. 
Aiding blood and bone health
Raspberries are a good sauce of vitamin K, which your body needs for absorbing calcium and clotting the blood. 
Raspberries can also trigger a stem cell response to increase healthy bone growth. 
Bottom Line: There are several benefits of raspberries. While there is research supporting some of the effects, there’s not 100% certainty that this fruit works.
Raspberry Ketones Side Effects
Raspberry Ketones are GRAS (generally recognized as safe) as an approved food additive by the Federal Drug Agency (FDA) since 1965. 
Studies have shown that the form of rheosmin extracted from raspberries can boost metabolism as well as increase oxygen consumption, heat production and enzyme activity in some fat cells. 
This may be an ideal way to use up some of these fat stores and decrease weight. 
Suggested dosage of raspberry ketone supplement, based on studies conducted on rats, is 100mg – 1400mg per kg for humans. 
Because of the stimulating effect it has on the body, it may cause a feeling of jitteriness like caffeine. 
Bottom Line: It is important to note, however, that currently the research conducted on raspberry ketones has mostly been done in vitro, not in human trials, human studies have also included other supplements and were not conclusive. 
What are Raspberry Ketones Used For?
There are several uses for rapsberry ketones. But, several raspberry ketone supplements don’t actually contain real raspberries.
Making raspberry ketones using actual raspberries would be outrageously extensive.
You’ll need more than 90 pounds of raspberries to make a single dose of raspberry ketone.
The molecular structure of raspberry ketones led researchers to study the compound further.
Researchers suspected that since the structures of these molecules looked similar, perhaps raspberry ketones could have a similar metabolic effect.
Researchers discovered that raspberry ketones had two specific effects on the fat cells of rats. 
Fat breakdown increased because of raspberry ketones effect on norepinephrine, a fat burning hormone.
Bottom Line: Since producing a supplement from actual raspberries ketones requires so many raspberries they are typically synthetic.
What is a Ketone?
Interest in raspberry ketones comes from the word “ketone” and its connection to the ketogenic diet.
A ketogenic diet is a low carb diet where you’ll eat lower amounts of carb and higher amounts of fats. In turn, you’ll use fat as energy.

Raspberry ketones do not work the same as a ketogenic diet.
Bottom Line: Raspberry ketones, found in products like Raspberry Ketone Plus, is a natural compound giving raspberries and certain other fruits their distinct flavor and aroma. While ketone is in the name, it’s not necessarily connected to the Keto Diet.
What are Raspberries Good For?
Both metabolism and blood sugar levels play a large role in the body’s ability to shed fat.
This led researchers to believe that increasing adiponectin levels could lead to weight loss in people who need to reduce their weight.
Furthermore, it’s also possible to raise adiponectin levels without the use of supplements. Some studies have shown that adiponectin levels can increase significantly with exercise. They can also be increased by drinking coffee.   
Bottom Line: Raspberry ketones are molecularly similar to two compounds. Both shown to help burn fat. They help to break down fat cells at a more rapid rate and increase the release of the hormone adiponectin.
Is There Research Into Raspberry Ketones?
Studies involving mice and rats use synthetic raspberry ketones.
There are no studies on humans relating to the effectiveness of raspberry ketones.
However, there was study using similar compounds, but there is still nothing to show the effects of raspberry ketones alone 
For example, one study gave an unhealthy, fatty diet to mice. A portion of the mice also received raspberry ketones. 
There was a 10% difference in the weight of the rats that received the raspberry ketones and those that did not.
A similar study involving 40 rats showed that the rats ingested the raspberry ketones showed higher levels of adiponectin as well. 
Bottom Line: Although several studies do show that the main ingredient in products like Purely Inspired Raspberry Ketones has had a positive, fat reducing effect on rats, the dosage they were given would far exceed the recommended amount that is safe for humans to consume.
What Else Can Raspberry Ketones be Used For?
There are other benefits to using raspberry ketones.
Some studies have shown the cosmetic benefits of raspberry ketones. 
When used as part of a topical cream, subjects have shown increased hair growth and skin elasticity among other things.
Although it showed good results, this study was not perfect. 
Bottom Line: There is research into the effects of raspberries when used topically.
