Mushrooms: A Zinc-Rich Superfood?

Mushrooms are a type of fungus, often considered a vegetable, that are packed with vitamins and minerals. They are a great addition to your diet, adding flavour to many recipes. They are also a good source of protein and vitamins B, C, D, and K. One cup of sliced raw mushrooms contains 0.4 mg of zinc, according to the USDA. They also contain other vital vitamins and minerals, such as vitamin B riboflavin, calcium, potassium, copper, and manganese.

Zinc in mushrooms: 100g of cooked white mushrooms contain 0.9mg of zinc

Zinc is an essential mineral that cannot be synthesised by the human body and must be included in one's diet. It is commonly found in animal products, but there are also plant-based sources of zinc, including mushrooms.

Mushrooms are a type of fungus and are packed with vitamins and minerals. They are a good source of zinc, with 100g of cooked white mushrooms providing 0.9mg of zinc. This equates to 6% of the daily value (DV) of zinc. For reference, the current DV for zinc is 15mg.

Other types of mushrooms also contain zinc, and the amount can vary depending on the variety and preparation method. For example, a cup of sliced raw mushrooms contains 0.4mg of zinc, while a cup of diced cooked mushrooms provides 1.4mg.

Zinc plays an important role in the body and has several health benefits. It is known to support the immune system and may help prevent colds and other illnesses. A zinc deficiency can lead to various health issues, including weight loss, diarrhoea, vision problems, skin rashes, and a reduced sense of taste and smell.

In addition to zinc, mushrooms contain other essential nutrients such as protein, vitamins B and D, and antioxidants. They are also a good source of potassium, folate, and fibre. When buying fresh mushrooms, look for ones that are firm, dry, and unbruised. Store them in the refrigerator and wash them thoroughly before use.

Other zinc-rich foods: crab, lobster, beef, lamb, and chickpeas

Mushrooms are a source of vitamins, minerals, protein, and antioxidants. However, there is no indication that they contain zinc.

Other zinc-rich foods

Crab and Lobster

Shellfish, including crab and lobster, are excellent sources of zinc. Alaska king crab, for example, contains 7.62 mg of zinc per 100 grams, which is 69% of the daily value (DV) for males and 95% for females. Smaller shellfish, like shrimp and mussels, are also good sources, providing nearly 15% of the DV for males and around 20% for females per 100-gram serving.

Beef

Beef is another great source of zinc. A 100-gram serving of raw ground beef provides 4.79 mg of zinc, which is about 44%-60% of the DV.

Lamb

Lamb is a type of red meat that is rich in many vitamins and minerals, including zinc. Lamb also contains bioactive nutrients and antioxidants that may provide additional health benefits.

Chickpeas

Chickpeas are legumes that contain a range of nutrients, including zinc. However, it is important to note that legumes also contain phytates, which inhibit the absorption of zinc and other minerals. As a result, zinc from legumes is not absorbed as well as zinc from animal products. Despite this, chickpeas can be an important source of zinc for those following vegan or vegetarian diets.

Mushrooms' other vitamins: B vitamins, vitamin D, vitamin C, and folate

Mushrooms are a source of several vitamins, including B vitamins, vitamin D, vitamin C, and folate.

B Vitamins

Mushrooms contain several B vitamins, including thiamine, riboflavin, B6, and B12. B vitamins help the body get energy from food and form red blood cells. They also play a role in brain health.

Vitamin D

Mushrooms are the only vegan, non-fortified dietary source of vitamin D. The two main forms of vitamin D are D2, found in fungi and yeast, and D3, found in animals. When commonly consumed mushroom species are exposed to ultraviolet (UV) radiation or sunlight, they can generate nutritionally relevant amounts of vitamin D. The most common form of vitamin D in mushrooms is D2, with lesser amounts of vitamins D3 and D4. Vitamin D-enhanced mushrooms have the potential to be a primary source of dietary vitamin D for vegans and vegetarians.

Vitamin C

Mushrooms also contain vitamin C, with one cup of mushrooms providing around 1.47 mg of this nutrient. The recommended daily intake of vitamin C is 75-90 mg. Vitamin C is important for cardiovascular health, and a deficiency has been linked to an increased risk of cardiovascular disease.

Folate

A cup of sliced raw mushrooms contains 11.9 micrograms (mcg) of folate. Folate is especially important during pregnancy, and current guidelines recommend that adults consume 400 mcg of folate daily, while pregnant people should aim for around 600 mcg.

Mushrooms' other minerals: potassium, selenium, and copper

Mushrooms are a source of many nutrients, including vitamins, minerals, protein, and antioxidants. While they do not contain zinc, they are a good source of potassium, selenium, and copper.

A cup of mushrooms contains around 223 mg of potassium. Potassium is important for regulating blood pressure and reducing the risk of cardiovascular disease. The American Heart Association recommends consuming around 2,600 mg of potassium per day for females and 3,400 mg per day for males. However, people with certain conditions, such as kidney disease, may need to limit their potassium intake and should consult a doctor for personalized advice.

Selenium is another important mineral found in mushrooms. While the amount of selenium in mushrooms can vary depending on the soil they are grown in, they are still a valuable source of this mineral. Selenium is essential for health, and a deficiency can lead to serious problems. However, it is important to note that too much selenium can also be harmful, so it is important to consume it in moderation.

Copper is also present in mushrooms, although the amount may vary depending on the type of mushroom. Copper is an essential mineral that plays a vital role in energy production, brain function, and the formation of red blood cells. It is also important for maintaining healthy bones, blood vessels, and nerves.

Overall, mushrooms are a nutritious food that can contribute to a healthy diet. They are low in calories and provide a good source of minerals, including potassium, selenium, and copper, which offer various health benefits.

Mushrooms' health benefits: may help prevent cancer, lower blood pressure, and control obesity

Mushrooms are a great source of protein, vitamins, minerals, and antioxidants. They contain B vitamins, including thiamine, riboflavin, B6, and B12, as well as vitamin D, folate, and choline. The choline in mushrooms helps with muscle movement, learning, and memory, and vitamin D is important for maintaining healthy bones and overall health.

In terms of their health benefits, mushrooms may help prevent certain types of cancer, including prostate, colorectal, and breast cancer. For example, Polysaccharide K (PSK) is an active compound found in turkey tail mushrooms that is used to treat cancer in Japan. Additionally, studies have shown that reishi mushrooms may help strengthen the immune system in patients with lung cancer.

Mushrooms may also help lower blood pressure. The Heart & Stroke Foundation of Canada recommends eating more foods rich in potassium, such as mushrooms, to help control blood pressure. This is because high blood pressure can damage the lining of arteries and increase the risk of heart disease, stroke, and kidney disease.

Furthermore, mushrooms may help control obesity. They have antioxidant and anti-inflammatory properties, which can protect against obesity-related complications such as hypertension and dyslipidemia. Animal studies have shown that the regular consumption of mushrooms can lead to a reduction in body weight and stored fat mass by increasing energy and fat burning and regulating glucose hemostasis.

While mushrooms have many potential health benefits, it is always important to consult a doctor or registered nutritionist for personalized advice and information.
