7 Impressive Benefits of oyster mushrooms nz
oyster mushrooms nz, 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.
This article covers seven impressive benefits of oyster mushrooms nz.
1. Rich in nutrients
oyster mushrooms nz 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):
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.
oyster mushrooms nz are a good source of fiber, protein, and a variety of vitamins and minerals.
2. Source of antioxidants
oyster mushrooms nz provide antioxidants, which are substances that help reduce cellular damage in your body (4Trusted 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.
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 nz 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 (13Trusted Source).
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 (15).
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).
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. ostreatusreduced 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).
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 (16Trusted Source).
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 nz 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).
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).
However, studies focusing on the potential immune health-promoting properties of whole oyster mushrooms — and not just extracts and supplements — are needed.
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:
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).
oyster mushrooms nz 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 grain dishes.
Sauté them with olive oil and garlic for a nutritious side dish.
Chop and add them to sauces and gravy.
Use them in egg dishes like frittatas, omelets, and quiches.
Grill them on skewers with vegetables and a protein source like shrimp or chicken.
Roast them in the oven.
As you can see, they can be prepared in many ways, so don’t be afraid to try them in your favorite savory recipes.
oyster mushrooms nz are tasty and pair well with a variety of foods. Use them in meals like soups, stews, pasta dishes, and stir-fries.
The bottom line
oyster mushrooms nz are a popular type of mushroom linked to several health benefits.
In addition to being highly nutritious, they may promote heart and immune system health, encourage healthy blood sugar control, and provide antioxidant and anti-inflammatory effects.
