A) BERBERIS BERRIES. HIGH IN NUTRIENTS Barberries are highly nutritious. They are rich in carbs, fiber, and several vitamins and minerals.

In particular, the berries are an excellent source of vitamin C, an antioxidant that may help protect against cellular damage, which can lead to heart disease and cancer (2Trusted Source).

A 1/4-cup (28-gram) serving of dried barberries contains (3):

Calories: 89

Protein: 1 gram

Fat: 1 gram

Carbs: 18 grams

Fiber: 3 grams

Vitamin C: 213% of the Daily Value (DV)

Iron: 15% of the DV

In addition, barberries contain zinc, manganese, and copper, all of which are trace minerals that play significant roles in immunity and disease prevention.( 7Trusted Source).

1) The bright red color of the berries comes from anthocyanins, which are plant pigments that may boost your brain and heart health, among other benefits (8Trusted Source).

2) Contain beneficial plant compounds

Barberries are rich in berberine, a unique plant compound that may be associated with several health benefits.

Berberine is a member of the alkaloid family, a group of compounds known for their therapeutic effects (9Trusted Source, 10Trusted Source).

3) Studies have shown that it acts as a powerful antioxidant, combating cell damage caused by reactive molecules called free radicals (11Trusted Source).

Also, berberine may help reduce blood sugar and cholesterol levels, slow the progression of certain cancer cells, fight infections, and have anti-inflammatory effects (12Trusted Source, 13Trusted Source).

What’s more, barberries contain other compounds that may have health benefits, such as other alkaloids and organic acids. Yet, most research has focused on berberine (12Trusted Source).

SUMMARY

Barberries contain a high concentration of berberine, a therapeutic compound with antioxidant activity that may provide several health benefits.

Contain beneficial plant compounds

Barberries are rich in berberine, a unique plant compound that may be associated with several health benefits.

Studies have shown that it acts as a powerful antioxidant, combating cell damage caused by reactive molecules called free radicals (11Trusted Source).

3) Barberries — and in particular their berberine content — may play a role in managing diabetes, a chronic disease marked by high blood sugar levels.

Specifically, berberine has been shown to improve how your cells respond to the hormone insulin, which regulates the amount of sugar in your blood. In turn, this may help lower your blood sugar levels (14Trusted Source, 15Trusted Source).

One 3-month study in 36 adults with type 2 diabetes found that taking 1.5 grams of berberine per day led to a significant 2% reduction in hemoglobin A1c — a measure of your average blood sugar control over the past 3 months — compared with baseline values (16Trusted Source).

In fact, researchers found that the beneficial effects of berberine on blood sugar and hemoglobin-A1c were comparable to those of the traditional diabetes drug METFORMIN (16Trusted Source).

Another 8-week study in 30 people with type 2 diabetes found that those who took 2 mg of dried barberry fruit extract daily had reduced hemoglobin A1c levels and significantly lower blood sugar levels, compared with a placebo group (17Trusted Source).

4) Can help treat diarrhea

Barberries have been used to treat diarrhea for centuries.

This is likely due to their high concentration of berberine, which helps slow the transit of feces through your gut by inhibiting certain receptors, thus PREVENTING, (20Trusted Source).

In fact, one of the oldest human studies on berberine found that it treated diarrhea caused by infections from certain bacteria, including E. coli (21Trusted Source).

Furthermore, one study in 196 adults with diarrhea-predominant irritable bowel syndrome (IBS-D) found taking 800 mg of berberine hydrochloride per day significantly decreased the frequency of diarrhea and the urgent need to defecate, compared with a placebo (22Trusted Source).

While these results are interesting, more human research is needed to better understand how berberine and barberries may help treat diarrhea.

5)5. May protect against metabolic syndrome

Eating barberries may help prevent metabolic syndrome, which is a cluster of risk factors that increase your risk of heart disease and diabetes.

In particular, barberries may protect against obesity and high blood sugar, cholesterol, triglyceride, and blood pressure levels — all of which are risk factors for this syndrome (23Trusted Source).

One 8-week study in 46 patients with type 2 diabetes found that drinking around 7 ounces (200 mL) of barberry juice per day significantly reduced blood pressure, triglyceride, cholesterol, and blood sugar levels, compared with a placebo (24Trusted Source).

In addition to improving the risk factors for metabolic syndrome, barberries may help decrease oxidative stress in those who already have the condition.

Oxidative stress results from underlying cell damage caused by reactive molecules called free radicals. Having too much oxidative stress — and not enough antioxidants to fight it — can lead to heart disease and other health issues (25Trusted Source).

A 6-week study in 106 people with metabolic syndrome showed taking 600 mg of dried barberry per day significantly decreased oxidative stress compared with a placebo (25Trusted Source).

Based on these results, eating the berries may help decrease your chances of developing risk factors for metabolic syndrome, as well as reduce oxidative stress associated with it. Nevertheless, more research is needed.

6)Test-tube studies have shown that barberry extract can fight inflammation.

This is likely because berberine acts as a powerful .

It helps treat inflammatory dental diseases like gingivitis, which is marked by plaque buildup, swelling, and irritation of the gums.

One study in 45 boys between the ages of 11 and 12 found that applying barberry dental gel for 21 days reduced plaque and gingivitis significantly more than a placebo

The study also indicated that barberry gel was more effective than traditional anti-plaque toothpaste, but the results were not significant .

These results suggest that barberry treatments may promote good dental health, but more research is needed.

7)There are several different ways in which barberries may exert anticancer effects, all of which are related to berberine.

Since berberine acts as an antioxidant, it may help fight underlying oxidative damage associated with cancer development (28Trusted Source).

Additionally, berberine may prevent cancer cell replication, and inhibit enzymes involved in the life cycle of cancer cells (28Trusted Source).

Several test-tube studies have shown that berberine prevents tumor growth and initiates cell death in human prostate, liver, bone, and breast (32Trusted Source).

However, research is limited to test-tube studies, and more research is needed to better understand the potential role of barberries in cancer treatment and prevention)

8)Barberries may play a role in treating acne, a skin condition characterized by inflamed bumps and pimples.

Specifically, berberine and other compounds in barberries may help fight inflammation and infections associated with acne (33Trusted Source).

One study in adolescents with moderate to severe acne found that taking 600 mg of dried barberry extract per day for 4 weeks significantly reduced the average number of lesions, compared with a placebo (33Trusted Source).

The study concluded that extract from this berry may be a safe and effective treatment option for teenagers with acne, but more extensive research is needed.

9)Easy to add to your diet

Barberries are known to have a tart, slightly sweet flavor and can be eaten raw, in jam, or as a component of rice dishes and salads. They can also be juiced or used to make tea.

Supplemental forms of barberry include dried capsules, liquid extracts, and ointments or gels made from whole berries or berberine extract. However, due to the limited research in humans, there is no recommended dosage for barberry or berberine supplements.

While barberries are generally recognized as safe for most people, there are some reports that large amounts or high supplemental doses can cause stomach upset and diarrhea (15Trusted Source, 16Trusted Source, 34Trusted Source).

What’s more, there is no research on the effects of barberries in children or pregnant or lactating women. Therefore, barberry or berberine supplements should be avoided in these populations (34Trusted Source).

To reap the possible health benefits of barberries, try using whole, fresh berries in your cooking.

If you are interested in taking a barberry or berberine supplement, consult your healthcare provider first and look for a supplement that has been tested for quality by a third party.

B) RAW BROCCOLI AND ITS BENEFITS

By Signe Dean

Scientists found a healthier way

Broccoli has gained a reputation as an excellent vegetable due to its high levels of a particularly beneficial compound called SULFORAPHANE.

With some studies showing how this compound plays a role in blood sugar control and potentially even has anti-cancer benefits, it’s no wonder that broccoli pills are on the rise.

HOW EVER, A PREVIOUS STUDY SHOWED THAT EATING THE WHOLE BROCCOLI RAW, GETS YOU MORE SULFORAPHANEMUCH MORE, THAN TAKING A SUPPLEMENT

They arrived at a clear winner, publishing their results in 2018 in the Journal of Agricultural and Food Chemistry – but it’s a tough sell if you have better things to do with your time.

There’s a method behind the madness, though. SULFORAPHANE DOESN’T just sit there in the BROCCOLI FLORETS, ready to be consumed. Instead, the vegetable contains SEVERAL compounds called GLUCOSINOLATES.

It ALSO contains the enzyme MYROSINASE, which plants have evolved for defending themselves against HERBIVORES. Through what’s known as ‘MYROSINASE ACTIVITY’, THE GLUCOSINOLATES GET transformed into SULFORAPHANE, WHICH IS WHAT WE WANT.

To kick MYROSINASE activity into gear, you need to do DAMAGE to the broccoli, so you’d think cooking would do the TRICK.

Studies have shown that COMMON broccoli COOKING methods, like boiling and microwaving, SERIOUSLY REDUCE the amount of glucosinolates in the vegetable – even if you just zap it for a couple minutes. And myrosinase is SUPER SENSITIVE to heat, too.

Hence, by far the largest amount of SULFORAPHANE, you can get from broccoli is by MUNCHING ON RAW FLORETS. .

BABY RAW BROCCOL The team bought a bunch of broccoli from the local market and set to work, measuring the levels of compounds in the vegetables as they went.

First, they basically pulverized the broccoli, chopping it into 2-millimeter pieces to get as much MYROSINASE activity going as possible (REMEMBER, the ACTIVITY HAPPENS when BROCCOLI IS DAMAGED.

And that’s exactly what the team found – the broccoli that was stir-fried right away had 2.8 times less sulforaphane than the one left to ‘develop’ for longer.

The study was published in the Journal of Agricultural and Food Chemistry.

PLEUROTUS OSTREATUS, the “OYSTER MUSHROOM”, OYSTER FUNGUS, HIRATAKE, or PEARL OYSTER MUSHROOM is a common EDIBLE mushroom. It is one of the more commonly sought wild mushrooms, though it can also be cultivated on straw and other media.

Studies have shown that the amount of ERGOTHIONEINE in PLEUROTUS mushrooms is the largest compared to all other foods. ERGOTHIONEINE REDUCES the HARMFUL effects of ULTRAVIOLET rays of the sun on collagen and human cells in general, slows down aging and helps prevent cancer. Only 18 gr. of mushrooms are enough to cover the body’s monthly needs for this valuable amino acid.

ERGOTHIONEINE is used in cosmetic products, as well, to prevent wrinkles and reduce signs of skin aging, while in medicine it is used as a drug. People take ERGOTHIONEINE for LIVER damage, CATARACTS, ALZHEIMER’S disease, DIABETES and HEART disease.

A LONGITUDINAL study conducted in Sweden6 involved 3200 adult men and women.

ANALYSIS of blood5 METABOLITES for cardiovascular7 disease risk found that of 112 METABOLITES measured at baseline, plasma ERGOTHIONEINE levels were MOST strongly associated with reduced risk of cardiovascular disease and mortality after 21-24 years of follow-up. The study authors concluded that increasing plasma ERGOTHIONEINE levels through diet may reduce the risk of cardiovascular disease and mortality.

The various variations of green salad with grilled pleurotus mushrooms are a complete, delicious and healthy summer meal. During heat treatment, the ERGOTHIONEINE content of mushrooms increases.

7 Impressive Benefits of Oyster Mushrooms

Medically reviewed by Kim Rose-Francis RDN, CDCES, LD, Nutrition — Written by Jillian Kubala, MS, RD on May 26, 2021

Oyster mushrooms, or Pleurotus species, are a group of gilled mushrooms. While mushrooms are classified as fungi, which are technically different from plants, they are a great addition to any meat-free diet.

There are around 40 types of oyster mushrooms, including Pleurotus ostreatus (or P. ostreatus), commonly known as the American oyster mushroom. All types are edible and are commonly enjoyed in dishes like pasta and stir-fries (1Trusted Source).

They’re known for their impressive health-promoting properties and contain a variety of powerful compounds. In fact, they’ve been used in traditional medicine approaches for centuries (1 Trusted Source, 2 Trusted Source).

This article covers seven impressive benefits of oyster mushrooms.

Dominique Chapman/Stocksy United

1. Rich in nutrients

Oyster mushrooms are loaded with fiber, vitamins, minerals, and other important nutrients. They’re also low in carbohydrates, so they’re a good choice for people following low carb dietary patterns.

Here’s the nutritional content of 1 cup (86 grams) of raw P. ostreatus oyster mushrooms (3Trusted Source):

Calories: 28

Carbs: 5 grams

Protein: 3 grams

Fat: <1 gram

Fiber: 2 grams

Niacin: 27% of the Daily Value (DV)

Pantothenic acid (vitamin B5): 22% of the DV

Folate: 8% of the DV

Choline: 8% of the DV

Potassium: 8% of the DV

Iron: 6% of the DV

Phosphorus: 8% of the DV

Zinc: 6% of the DV

The mushrooms also contain smaller amounts of other nutrients, including vitamin D and selenium.

Summary

Oyster mushrooms are a good source of fiber, protein, and a variety of vitamins and minerals.

2. Source of antioxidants

Oyster mushrooms provide antioxidants, which are substances that help reduce cellular damage in your body (4Trusted Source).

For example, seven phenolic compounds have been detected in P. ostreatus extracts, including gallic acid, chlorogenic acid, and naringenin — all of which act as antioxidants in your body (5Trusted Source, 6Trusted Source, 7Trusted Source, 8Trusted Source).

These mushrooms also contain the amino acid ergothioneine, which has powerful antioxidant effects (9Trusted Source).

A 2007 study in rodents found that treatment with oyster mushroom extract improved antioxidant levels and lowered certain inflammatory markers, including malondialdehyde (MDA), in older rats (10Trusted Source).

Similarly, a 2020 rat study observed that the extract showed antioxidant effects and helped reduce liver damage caused by toxic chemicals (11Trusted Source).

What’s more, a 2016 test-tube study found that extract from gray oyster mushroom (Pleurotus pulmonarius) inhibited oxidative damage to human artery cells and prevented oxidation of LDL (bad) cholesterol, possibly thanks to the amino acid ergothioneine (12Trusted Source).

Oxidation of LDL (bad) cholesterol is involved in the process of atherosclerosis, which is the buildup of plaque in the arteries that can lead to heart disease (12Trusted Source).

Although animal and test-tube studies suggest that oyster mushrooms provide antioxidants and may protect against cellular damage, more research in humans is needed.

Summary

Oyster mushrooms are a good source of antioxidants. According to test-tube and animal research, they may protect against cellular damage, but studies in humans are needed to confirm this.

3. May benefit heart health

Oyster mushrooms may promote heart health by reducing heart disease risk factors like high cholesterol and high blood pressure.

P. ostreatus is especially high in several compounds that benefit heart health, including fibers called beta-glucans.

Beta-glucans are fermented by gut bacteria to produce short-chain fatty acids that can help reduce cholesterol production in your body. Interestingly, P. ostreatus provides twice as many beta-glucans as white button mushrooms (A. bisporus) (14Trusted Source).

A small 2011 randomized control trial in 20 people found that eating a soup containing 30 grams of dried P. ostreatus for 21 days decreased triglycerides, total cholesterol, and oxidized LDL (bad) cholesterol levels compared with placebo treatment.

Plus, a 2020 review of eight human studies found that P. ostreatus intake helped lower blood sugar, triglycerides, blood pressure, and insulin levels, all of which could decrease heart disease risk.

However, the authors acknowledged that all available studies have a high risk of bias and that future well-designed studies are needed to better understand how P. ostreatus intake may improve heart health (16Trusted Source).

Summary

Some research suggests that eating oyster mushrooms may reduce heart disease risk factors like high blood pressure and cholesterol. However, more well-designed human studies are needed.

4. May promote blood sugar regulation

In addition to promoting heart health, oyster mushrooms may help regulate blood sugar levels.

A study in 22 people with and without type 2 diabetes found that taking powdered P. ostreatus reduced post-meal blood sugar levels. The authors speculated that the mushrooms increased sugar use in body tissues while inhibiting certain blood sugar-increasing proteins (16Trusted Source, 17Trusted Source).

Similarly, a 2007 study in 30 hospitalized people with type 2 diabetes found that eating 150 grams of cooked P. ostreatus daily for 7 days reduced fasting blood sugar by 22% and post-meal blood sugar by an average of 23% (16Trusted Source, 18Trusted Source).

After participants had stopped the mushroom treatment for 1 week, fasting and post-meal blood sugar increased by an average of 13% and 20%, respectively. The treatment also significantly reduced participants’ blood pressure, cholesterol, and triglyceride levels (16Trusted Source, 18Trusted Source).

What’s more, a study in 27 men with type 2 diabetes and high blood pressure found that treatment with 3 grams of powdered P. ostreatus powder per day for 3 months significantly reduced hemoglobin A1c (HbA1c), a marker for long-term blood sugar control (Trusted Source).

A 2020 review suggested that these potential blood sugar-lowering effects may be attributed to the mushroom’s high concentration of beta-glucans, as this type of fiber slows down carbohydrate digestion and absorption (Trusted Source).

Summary

Studies in people with and without diabetes have found that oyster mushrooms may improve blood sugar levels and other aspects of health when taken as a supplement or consumed as part of the diet.

5. Immune-supportive benefits

Oyster mushrooms may support your immune system in several ways.

For example, pleuran — a type of beta-glucan fiber derived from P. ostreatus — has been shown to have immune-modulating properties. Plus, the mushrooms may boast antiviral and antibacterial effects.

In a 130-day study in 90 people with herpes simplex virus type 1 (HSV-1), treatment with a combined pleuran, vitamin C, and zinc supplement improved HSV-1 symptoms and reduced the duration and severity of respiratory symptoms more than vitamin C alone (20Trusted Source).

Pleuran treatment has also been shown to significantly improve symptoms in children with recurrent respiratory tract infections and significantly reduce the incidence of upper respiratory tract infections in athletes (21Trusted Source, 22Trusted Source).

Additionally, an 8-week study in 41 people found that compared with placebo, taking a daily oyster mushroom extract supplement heightened the immune system by activating interferon-γ (IFN-γ), a molecule that plays a critical role in protecting against infection (23Trusted Source).

These mushrooms have also been shown to have antiviral and antibacterial effects (24Trusted Source, 25Trusted Source).

However, studies focusing on the potential immune health-promoting properties of whole oyster mushrooms — and not just extracts and supplements — are needed.

Summary

Researchers have speculated that certain extracts from oyster mushrooms may support immune health. However, human studies focusing specifically on the immune benefits of eating the mushrooms are needed to learn more.

6. Other potential benefits

In addition to the possible benefits listed above, research suggests oyster mushrooms may promote health in other ways:

Potential anti-tumor properties. Research in test tubes and animals suggests that these mushrooms may provide anti-tumor effects. However, human research is lacking (26Trusted Source, 27Trusted Source, 28Trusted Source).

Gut health benefits. A 2021 rodent study found that supplementing the diet of obese rats with oyster mushrooms decreased the growth of pathogenic bacteria and increased the production of beneficial short-chain fatty acids in their guts (29Trusted Source).

Anti-inflammatory effects. These mushrooms contain anti-inflammatory compounds. A 2020 rat study found that oral treatment with P. ostreatus extract significantly reduced induced paw inflammation (30Trusted Source).

Summary

Oyster mushrooms may have anti-tumor, anti-inflammatory, and gut health-promoting properties. However, more research is needed to confirm these potential benefits.

7. Versatile and delicious

In addition to offering potential health benefits, these mushrooms are prized for their culinary uses. All their parts are edible, including the caps, gills, and stems.

Here are a few ways to incorporate oyster mushrooms into your diet:

Add them to soups and stews.

Cook and add them to pasta and grains,
