Mushrooms' pH levels range from 6 to 7, making them near-neutral
Mushrooms are a nutritious food with high levels of vitamins, minerals, antioxidants, and dietary fibre. They are also low in fat and calories. In addition to these health benefits, mushrooms have a pH range of 6 to 7, which is near-neutral. This characteristic makes them suitable for a balanced diet as they help maintain overall dietary acidity.
The pH scale ranges from 0 to 14, with values below 7 indicating acidity and those above 7 indicating alkalinity. Many common acidic foods, such as citrus fruits and tomatoes, can have pH values as low as 2 to 4. In contrast, mushrooms' near-neutral pH means they can be incorporated into meals without greatly altering the overall acidity of the diet. This makes them a versatile ingredient that enhances flavour while promoting pH balance.
While mushrooms themselves have a near-neutral pH, they contain key nutrients like potassium, magnesium, and calcium that can enhance alkalinity in the body. Potassium, for example, is known to be beneficial for individuals with acid reflux as it can help balance the acidity in the stomach. Additionally, the alkaline nature of mushrooms may also contribute to their anti-inflammatory properties.
It is important to note that the pH levels of mushrooms can vary depending on the species and other factors. Oyster mushrooms, for instance, are known for their ability to acidify a highly alkaline substance. Furthermore, the method of preparation and cooking can also influence the final pH levels of mushrooms. Despite these variations, mushrooms generally fall within the mildly acidic to neutral range.

Oyster mushrooms can acidify a solution with a pH of 12+ to the mid-5s in a week
Oyster mushrooms are a unique variety of fungi that can thrive in a wide range of pH levels. While the ideal pH range for cultivating oyster mushrooms is between 7.8 and 8.5, they can tolerate and adapt to more acidic or alkaline conditions.
Oyster mushrooms exhibit a remarkable ability to acidify their surrounding environment. In a striking example, oyster mushrooms can acidify a solution with an initial pH of 12 or higher to the mid-5s within just one week. This capability highlights their efficiency in acidifying exudates, a process known as "fungal weathering" observed in natural settings.
The pH level of the substrate and watering frequency play critical roles in the growth and development of oyster mushrooms. In controlled experiments, researchers found that a pH level of 5.5 for the substrate, combined with a watering frequency of Im + 12 hours, yielded the highest number of fruiting bodies and overall mushroom harvest.
Maintaining the optimal pH range is crucial for successful oyster mushroom cultivation and preventing contamination. A pH level below 7.8 may hinder the growth of oyster mushroom mycelium, while a pH above 9 can be detrimental, slowing down mycelium growth and fostering the development of bacterial colonies.
Oyster mushrooms are not the only variety with acidifying properties. Other species, such as A. rubescens, S. luteus, and X. ferrugineus, have also demonstrated the ability to acidify their growth medium, albeit over a longer period of eight incubation weeks.

Mushrooms are a good source of protein and amino acids
Mushrooms are one of the few plant-based proteins that have a similar quality to animal proteins. They are a complete protein source, meaning they contain all nine essential amino acids that the human body needs but cannot produce on its own. These include leucine and lysine, which are not commonly found in many plant-based foods. In addition, mushrooms have a high branched-chain amino acid (BCAA) content, which is usually found in animal-based protein sources.
The protein content of mushrooms varies between different types and species. For example, oyster mushrooms, also known as "steak mushrooms" due to their size and texture, contain 2.2g of protein per 100g serving. Meanwhile, the mean protein content of all examined mushrooms was found to be 20.14g per 100g.
Mushrooms have gained attention as a potential protein alternative due to their nutritional value, quality, digestibility, and biological benefits. They are also more environmentally sustainable than animal-based proteins, as meat production contributes significantly to greenhouse gas emissions and requires large amounts of land for livestock.
In addition to their protein and amino acid content, mushrooms are a good source of various other nutrients. These include vitamins, minerals, and antioxidants. They are also a source of dietary fibre and potassium, which can contribute to improved cardiovascular health.

Consuming mushrooms can help balance the acidity in the stomach, reducing acid reflux symptoms
Acid reflux, or gastroesophageal reflux disease (GERD), is a common condition that causes discomfort and inconvenience. It occurs when stomach acid flows back into the oesophagus, leading to symptoms such as heartburn, chest pain, difficulty swallowing, and a sour taste in the mouth. While various treatment options are available, incorporating mushrooms into your diet may be a valuable natural remedy for managing acid reflux.
Mushrooms have an alkaline nature, meaning they have a higher pH level. Consuming alkaline foods helps balance the acidity in the stomach, reducing the occurrence of acid reflux symptoms. Additionally, mushrooms are low in fat and calories, which can be beneficial for maintaining a healthy body weight. Obesity is a risk factor for acid reflux. The high potassium content of mushrooms may also be beneficial in this regard.
Not all medicinal mushrooms offer the same benefits in combating acid reflux. Here are some specific types of mushrooms that have been associated with potential relief from acid reflux:
- Reishi mushrooms possess anti-inflammatory properties, which can help soothe the digestive tract and reduce reflux symptoms. They may also help manage stress and sleep, common triggers for acid reflux.
- Chaga mushrooms are rich in antioxidants, which can aid in reducing inflammation and supporting overall gut health.
- Lion's Mane mushrooms are rich in beta-glucans, providing prebiotic fibre for good gut bacteria. A balanced gut microbiome is crucial in maintaining overall health and managing acid reflux.
- Maitake mushrooms can help lower inflammation in the digestive tract, speed up digestion, and support a healthy immune system.
- Shiitake mushrooms improve digestion and support a healthy gut microbiome through their supply of beta-glucans. They are also known to support immune function.
While mushrooms can be a beneficial addition to a holistic approach to managing acid reflux, it's important to note that they may not be a cure-all. Individual reactions may vary, and some individuals may be allergic to mushrooms or experience digestive issues after consuming them. Always consult a healthcare professional before incorporating significant dietary changes or supplements, especially if you have any known allergies or gastrointestinal conditions.
