Mushroom Coffee: Metabolism Booster Or Myth?

Mushroom coffee is a blend of ground coffee and powdered medicinal mushrooms. It has gained popularity as a healthier alternative to regular coffee, with added health benefits and lower caffeine content. Some brands market mushroom coffee as a weight loss aid, claiming that it boosts metabolism and promotes fat burning. While mushrooms have been associated with various health benefits, there is limited research specifically on the effects of mushroom coffee. Although generally safe, some individuals with allergies, kidney issues, or caffeine sensitivity should exercise caution when consuming mushroom coffee.

Lack of research on health claims

While mushroom coffee is currently trending, the concept is far from new. According to online sources, mushrooms were used as a coffee substitute in Finland during World War II, and there is an extensive history of culinary and medicinal use of mushrooms in Asian countries, specifically for Chinese medicine.

Mushroom coffee is made by drying mushrooms, extracting their beneficial ingredients, and adding those to regular coffee. The most popular types of mushrooms used for this are medicinal mushrooms, such as Lion's Mane, Reishi, Turkey Tail, Chaga, and Cordyceps, rather than culinary mushrooms like shiitake and portobello.

Some of the health claims made by mushroom coffee brands include improved mental and physical performance, better immunity, and more restful sleep. Some brands even claim that mushroom coffee may help with weight loss by boosting your metabolism and promoting fat burning. However, there is very little research on medicinal mushrooms that includes humans. While studies conducted in test tubes or on animals do show some compelling health benefits associated with consuming medicinal mushrooms, the same benefits may not apply to humans.

There is also no meaningful research supporting the health claims made about mushroom coffee. Experts believe that enjoying the whole mushroom is the best way to get its benefits, so you might be better off adding whole mushrooms to your diet instead.

Additionally, mushrooms can cause digestive problems in some people, especially those with kidney conditions or sensitivity to grain. Plus, mushrooms have a lot of oxalates, which can lead to kidney stones. It is always recommended to talk with your doctor before changing your diet.

Nutritional value of whole mushrooms

While mushroom coffee is gaining popularity as a beverage with added health benefits, experts believe that consuming whole mushrooms is the best way to benefit from their nutritional value.

Mushrooms are a good source of copper, B vitamins, potassium, phosphorus, and iron. They are also a source of protein, with one cup of raw mushrooms providing 2.2 grams of protein. Mushrooms are low in calories, with the same serving size containing just 15 calories. They are also high in fiber, particularly the soluble fiber beta-glucan, which has been linked to a lower risk of type 2 diabetes.

In addition to their nutritional content, mushrooms contain various vitamins, minerals, and antioxidants. These compounds may help prevent several health conditions, including cancer and diabetes, when consumed as part of a nutritionally balanced diet. Mushrooms are also associated with improved cardiovascular health, with their high polyunsaturated fat content contributing to their reputation as a heart-healthy food choice.

When buying fresh mushrooms, look for those that are firm, dry, and unbruised. They should be stored in the refrigerator and washed and cleaned carefully before use. Mushrooms can be enjoyed in a variety of ways, including fresh, dried, canned, frozen, or powdered, and can be cooked or eaten raw.

Potential health risks

While there are purported health benefits of drinking mushroom coffee, there are also some potential health risks to consider. Firstly, there is a lack of human research on the effects of mushroom coffee, with most studies conducted on test tubes or animals. This means that information about safe dosages, potential medication interactions, and specific contraindications is limited.

Secondly, mushroom coffee may cause digestive issues, particularly for those with pre-existing kidney conditions or sensitivity to grains. This is due to the high levels of oxalates found in certain mushrooms used in mushroom coffee, such as Chaga, which can lead to the development of kidney stones.

Additionally, while mushroom coffee has about half the caffeine content of regular coffee, it still contains caffeine, which can cause side effects such as irritability, insomnia, gastrointestinal upset, rapid heart rate, and anxiety. These side effects may be milder compared to regular coffee, but they can still impact individuals with sensitivity to caffeine.

Furthermore, the cost of mushroom coffee is typically double that of regular coffee, making it a significant financial consideration for those interested in trying this beverage.

Lastly, while there are claims that mushroom coffee may aid in weight loss by boosting metabolism, there is limited research to support this assertion. The metabolism-boosting effects of caffeine may be counteracted by the body's natural regulatory mechanisms over time, leading to a tolerance development.

Therefore, while mushroom coffee may offer potential health benefits, it is important to be aware of these potential health risks and consult a healthcare professional before incorporating it into your diet, especially if you have any pre-existing health conditions.

Preparation methods

Mushroom coffee is made by blending ground coffee with powdered medicinal mushrooms. The process involves drying mushrooms, extracting beneficial compounds, and then blending them into regular coffee. The resulting beverage has a nutty and earthy flavour.

The preparation methods for mushroom coffee are similar to those for regular coffee. You can use a drip machine, French press, or instant coffee maker. The type of brewing method depends on the form of mushroom coffee purchased, such as mushroom coffee grounds, pre-made mushroom coffee lattes, instant mushroom coffee packets, or mushroom coffee pods.

To make mushroom coffee for weight loss, add 1-2 tablespoons of a mushroom coffee blend (containing reishi, cordyceps, or lion's mane mushrooms) to a cup of hot water. Stir well and adjust the quantity according to your preference. It is recommended to start with a small amount to ensure you don't have any adverse reactions. Gradually increase your intake to one or two cups daily for potential weight loss benefits.

It's important to note that while mushroom coffee may provide potential health benefits, it should be consumed in moderation and as a supplement to a healthy and balanced diet. Consult a healthcare professional before adding mushroom coffee to your diet, especially if you have any medical conditions or take medications.

History of medicinal mushrooms

The use of mushrooms for medicine dates back thousands of years. The oldest human mummy, dating back 4,000 years, was found with Piptoporus betulinus in his medicine kit, a mushroom used for its antibiotic properties and as a natural parasite killer. Ötzi, the Ice Man, who lived nearly 5,300 years ago, carried amadou and a birch polypore in a pouch to help him survive in the Alps of northern Italy. The First Peoples of North America used puffball mushrooms (Calvatia genus) as wound healers.

In ancient China, reishi mushrooms (Ganoderma lucidum) were valued as a tonic herb and were forbidden to common people. Ancient Greek and Roman writers, including Pliny, Seneca, and Dioscorides, debated the medicinal value of mushrooms. The Greek physician Hippocrates, circa 450 BCE, classified the amadou mushroom (Fomes fomentarius) as a potent anti-inflammatory and for cauterizing wounds. The Chinese alchemist Tao Hongjing, from the 5th century, described several medicinal mushrooms, including ling zhi (Ganoderma lucidum) and zhu ling (Dendropolyporus umbellatus), some of which were reportedly used by Shennong many centuries earlier. Egyptian hieroglyphics show mushrooms as the "plant of immortality," eaten only by nobles and pharaohs. The Aztecs also had sacred mushrooms, which they consumed in holy rituals.

In the 16th century, Inonotus obliquus was used in folk medicine for tumor treatment in Russia and Northern Europe. The discovery of penicillin from Penicillium rubens by Alexander Fleming in 1928 marked the beginning of modern scientific exploration of mushrooms for medicine. Since then, scientific investigation into the pharmacological properties of mushrooms has led to the development of various drugs, including statins, antifungals, immunosuppressants, antimalarials, and drugs with therapeutic effects on the central nervous system.

Mushrooms are nature's miniature pharmaceutical factories, producing a vast array of novel constituents. They are a special type of polysaccharide called beta glucan, which has been found to enhance the immune system and may have anti-cancer properties. Of the recognized mushroom species, about 7,000 (50%) are considered edible, and approximately 700 are considered safe with medicinal properties. However, despite their long history of use, mushrooms remain an enigma to many in the medical field.
