#Raspberries #are high in several powerful antioxidant compounds, including vitamin C, quercetin, and ellagic acid. Though, low in calories but high in fiber, vitamins, minerals and antioxidants. They may protect against diabetes, cancer, obesity, arthritis and other conditions and may even provide anti-aging effects.

The raspberries is the edible fruit of a multitude of plant species in the genus Rubus of the rose family, most of which are in the subgenus Idaeobatus; the name also applies to these plants themselves.  Raspberries are perennial with woody stems.

World production of raspberries in 2018 was 870,209 tonnes, led by Russia with 19% of the world’s total.

Red raspberries are the edible fruit of a plant species in the rose family.

There are many types of raspberries – including black, purple and golden – but the red raspberry, or Rubus idaeus, is the most common.

Red raspberries are native to Europe and Northern Asia and cultivated in temperature areas worldwide. Most US raspberries are grown in California, Washington and Oregon.

NUTRITION FACTS

LOW-CALORIE AND PACKED WITH NUTRIENTS

Raspberries boast many nutrients despite being low in calories.

Vitamin C: 54% of the Reference Daily Intake (RDI)

●Manganese: 41% of the RDI

Vitamin K: 12% of the RDI

Vitamin E: 5% of the RDI

B vitamin: 4-6% of the RDI

Iron: 5% of the RDI

Magnesium: 7% of the RDI

Phosphorus: 4% of the RDI

Potassium: 5% of the RDI

Copper: 6% of the RDI

Raspberries are a great source of fiber, packing 8 grams per 1-cup (123-gram) servings, or 32% and 21% of the RDI for women and men, respectively.

They provide more that half of the RDI for vitamin C, a water-soluble nutrients essential for immune function and iron absorption.

Raspberries also contain small amounts of vitamin A, thiamine, riboflavin, vitamin B6, calcium and zinc.

Raspberries are a good source of fiber and vitamin C. They contain many other important vitamins and minerals as well.

HEALTH BENEFITS OF RASPBERRIES

■ POTENT ANTIOXIDANTS MAY REDUCE DISEASE RISK

Antioxidants are plant compounds that help your cells fight and recover from oxidative stress.

Oxidative stress is linked to a higher risk of cancer, diabetes, heart disease and other illnesses.

Raspberries are high in several powerful antioxidant compounds, including vitamin C, quercetin and ellagic acid.

Compared to other berries, raspberries have a similar antioxidant content as strawberries, but only half as much as blackberries and a quarter as much as blueberries.

A review of animal studies suggests that raspberries and raspberry extracts have anti-inflammatory and anti oxidative effects that may reduce your risk of chronic diseases, such as heart disease, diabetes, obesity and cancer.

One eight-week study in obese, diabetic mice observed that those fed freeze-dried red raspberry showed fewer signs of inflammation and oxidative stress than the control group.

Another study in mice found that ellagic acid, one of raspberries antioxidants, may not only prevent oxidative damage but also repair damaged DNA.

Raspberries are high in antioxidants, plant compounds that protect against cell damage. Antioxidants may reduce your risk of certain chronic diseases.

■ HIGH FIBER AND TANNIN CONTENT MAY BENEFIT BLOOD SUGAR CONTROL

Raspberries are low in carbs and high in fiber, making them a smart choice for anyone watching their carbs.

One cup (123 grams) of raspberries has 14.7 grams of carbs and 8 grams of fiber, which of net digestible carbs per serving.

Raspberries also are unlikely to raise blood sugar levels.

The glycemic index (GI) is a measure of how quickly a given food increases your blood sugar. Though the GI for raspberries has not been determined, most berries fall into the low-glycemic category.

Additionally, studies show that raspberries may lower blood sugar and improve insulin resistance.

In animal studies, mice fed freeze-dried red raspberries alongside a high-fat had lower blood sugar levels and less insulin resistance than the control group.

The raspberry-fed mice also demonstrated less evidence of fatty liver disease.

Furthermore, raspberries are high in tannins, which block alpha-amylase, a digestive enzyme necessary for breaking down starch.

By blocking alpha-amylase, raspberries may reduce the number of carbs absorbed after a meal, which lessens the impact on your blood sugar.

Raspberries may positively impact your blood sugar due to their high fiber and tannin content.

■ MAY HAVE CANCER-FIGHTING PROPERTIES

Raspberries high levels of antioxidants may protect against cancer.

Berry extracts – including those of red raspberries – block the growth of and destroy cancer cells in test-tube studies on colon, prostate, breast and oral (mouth) cancer cells.

In one test-tube study, red raspberry extracts was shown to kill up to 90% of stomach, colon and breast cancer cells.

Another test-tube study demonstrated that sanguiin H-6 – an antioxidant found in red raspberries – led to cell death in over 40% of ovarian cancer cells.

Animal studies with raspberries also observed protective effects against cancer.

In one 10-week study on mice with colitis, those fed a diet of 5% red raspberries had less inflammation and a lower risk of cancer than the control group.

In another study, red raspberry extracts prevented the growth of liver cancers in mice. The risk of tumor development decreased with larger doses of raspberry extract.

Human studies are necessary before raspberries can be conclusively linked to cancer prevention or treatment.

Raspberries contain beneficial compounds that may combat various cancers, including those of the colon, breast and liver. However, studies in humans are needed.

OTHER POTENTIAL HEALTH BENEFITS

Because raspberries are high in many nutrients and antioxidants, they may provide other health benefits as well.

MAY IMPROVE ARTHRITIS

Raspberries have anti-inflammatory properties which may reduce symptoms of arthritis.

In one study, treated with red raspberry extracts had a lower risk of arthritis than rats in the control group. Additionally, those that developed arthritis experienced less severe symptoms than the control rats.

In another study in rats, those given raspberry extract had less swelling and joint destruction than the control group.

Raspberries are believed to protect against arthritis by blocking COX-2, an enzyme responsible for causing inflammation and pain.

MAY AID WEIGHT LOSS

One cup (123 grams) of raspberries has only 64 calories and 8 grams of fiber. What’s more, it’s made up of more than 85% water. This makes raspberries a filling, low-calorie food.

Additionally, their natural sweetness may help satisfy your sweet tooth.

The chemicals substances naturally found in raspberries may also aid weight loss.

In one study, mice were fed a low-fat diet, a high-fat diet or a high-fat diet supplemented with one of eight berries, including raspberries. Mice in the raspberries group gained less weight than mice only a high-fat diet.

Raspberry ketone supplements are widely promoted for weight loss. However, little research has been conducted on them.

In one study, mice fed a high-fat diet and given high doses of raspberry ketone gained less weight than mice in the control group.

The only human-based study on raspberry ketones and weight loss used a supplement containing several other substances, including caffeine, making it impossible to determine whether raspberry ketones were responsible for any positive effects.

While little evidence suggests that raspberry ketone supplements aid weight loss, eating whole, fresh raspberries may help you shed weight.

■ MAY COMBAT AGING

Raspberries are high in antioxidants, which can help reduce signs of aging by fighting free radicals in your body.

Antioxidants have been linked to longer lifespans in various animal models and show anti-aging effects in humans.

Raspberries are also high vitamin C, which is necessary for healthy skin. It may improve collagen production and reverse damage to skin caused by UV rays

In one eight-week study, aging rats fed a diet with 1% raspberries showed improved motor functions, including balance and strength.

Raspberries may reduce arthritis risk, aid weight loss and decrease signs of aging.
