Mushrooms are a nutritious food with a unique set of health benefits. They are low in calories and rich in essential nutrients, vitamins, minerals, and antioxidants. They are also a good source of selenium, which supports immune function. With a pH range of 6 to 7, mushrooms are considered mildly acidic to neutral. This characteristic makes them suitable for a balanced diet, as they do not greatly alter the overall acidity of meals. The alkaline diet, which has gained popularity due to celebrity endorsements, suggests that consuming alkaline foods can change your body's pH level and provide health benefits. However, there is limited scientific evidence supporting the diet's claims, and it is important to note that the body's pH levels are tightly controlled and not significantly influenced by food.

Mushrooms are a good source of selenium, supporting immune function
Selenium is an essential trace mineral with a variety of functions in the human body. It is important for proper thyroid function and supporting a healthy immune system. Selenium is incorporated into selenoproteins, which play a crucial role in regulating oxidative stress, redox, and other cellular processes in almost all tissues and cell types. Selenium deficiency has been linked to poor cardiovascular health, infertility, and cognitive decline.
Mushrooms are a good source of selenium, with portobello and shiitake mushrooms being particularly notable. The amount of selenium in mushrooms can vary depending on the type of mushroom and the selenium content of the soil in which they are grown. Rain, evaporation, pesticides, and pH levels can all impact soil selenium levels, making selenium deficiency more prevalent in certain regions.
The human body does not produce selenium, so it must be obtained through diet. Selenium-rich foods include Brazil nuts, bananas, eggs, beef, chicken, and mushrooms. Consuming a variety of these foods can help ensure adequate selenium intake.
Adequate selenium intake is important for optimal immune function. Selenium plays a role in initiating immunity and regulating excessive immune responses and chronic inflammation. Studies have shown that increasing selenium intake can enhance both cell-mediated and humoral immune responses. Selenium may also offer protection against certain pathogens and contribute to anti-viral immunity.
In summary, mushrooms are a good source of selenium, and selenium supports immune function by regulating oxidative stress and immune responses. However, it is important to note that while selenium deficiency can negatively impact health, excessive selenium intake may also have adverse effects. A balanced diet that includes a variety of selenium-rich foods, such as mushrooms, can help maintain optimal selenium levels and support overall health and immunity.

Mushrooms have a pH range of 6 to 7, making them mildly acidic to neutral
Mushrooms typically have a pH range of 6 to 7, which is considered mildly acidic to neutral. This pH level is determined using various measurement techniques, such as potentiometric methods and indicator papers, which provide precise readings for comparison with other foods. The pH scale ranges from 0 to 14, with values below 7 indicating acidity and above 7 indicating alkalinity. Therefore, mushrooms are primarily neutral, with a slight acidic lean.
The pH level of mushrooms is an important factor in understanding their nutritional composition and potential health benefits. They are known to be low in calories while being rich in essential nutrients, vitamins, minerals, and antioxidants. Mushrooms are particularly high in B vitamins, such as riboflavin and niacin, which are crucial for energy metabolism and nutrient absorption. Additionally, they are an excellent source of selenium, boosting immune function and helping combat oxidative stress.
The key nutrients found in mushrooms, such as potassium, magnesium, and calcium, can also enhance alkalinity. However, other components may contribute to their mildly acidic nature. The versatility of mushrooms in cooking can influence their final pH levels in a meal. Compared to highly acidic foods like citrus fruits and tomatoes, which typically have pH values between 2 and 4, mushrooms contribute to maintaining a balanced dietary acidity.
By incorporating mushrooms into your diet, you can benefit from their rich nutrient profile and promote a healthy pH balance. Their neutral pH levels make them suitable for combining with other foods without significantly altering the overall acidity of your diet. This characteristic positions mushrooms as a valuable addition to a diverse and nutritious meal plan.

Alkaline diets are based on the unproven claim that food affects blood pH
Alkaline diets are based on the claim that eating certain foods can alter the pH of your body. Proponents of the alkaline diet suggest that people monitor the pH of their urine to ensure that it is alkaline (over 7) and not acidic (below 7). However, it is important to note that pH varies across different parts of the body. While the stomach, for instance, is highly acidic to break down food, human blood is always slightly alkaline, with a pH of 7.35–7.45.
The alkaline diet theory, also known as the acid-ash hypothesis of osteoporosis, claims that to maintain this constant blood pH, the body takes alkaline minerals from bones to buffer acids from acid-forming foods. However, this theory does not consider the role of the kidneys and lungs in regulating blood pH. The kidneys reabsorb bicarbonate, which is formed from carbonic acid in the blood, while the lungs excrete carbonic acid, a volatile acid formed as part of the breathing process.
While the alkaline diet may promote healthy habits and limit processed foods, there is little evidence to support the claim that it can significantly alter blood pH. Food may have some impact on urine pH, but urine pH is not a reliable indicator of overall body pH or general health. The health benefits of the alkaline diet are more likely due to its focus on whole and unprocessed foods, including fruits, vegetables, nuts, and legumes.
Some studies suggest that the alkaline diet may offer specific benefits unrelated to body pH. For example, there is some evidence that chronic low back pain improves with the supplementation of alkaline minerals, which can slightly increase blood pH and intracellular magnesium, leading to improved back pain. Additionally, the alkaline diet's emphasis on reducing salt intake may positively impact bone health, as high salt consumption is detrimental to bone health.
In conclusion, while the alkaline diet may offer some health benefits, it is based on the unproven claim that food significantly affects blood pH. The diet's potential benefits are more likely due to its focus on whole, unprocessed foods and reducing dietary salt.

Mushrooms are nutrient-dense, offering vitamins, minerals, and antioxidants
Mushrooms are nutrient-dense, offering a range of vitamins, minerals, and antioxidants. They are a great addition to any diet, providing a delicate flavour and meaty texture to many recipes.
Mushrooms are the only vegan, non-fortified dietary source of vitamin D, which is essential for bone and immune health. They also contain vitamin B6, which helps our bodies form red blood cells, and selenium, which helps prevent cell damage. Mushrooms exposed to ultraviolet light are a good source of vitamin D, as the light transforms a substance called ergosterol, similar to cholesterol in animals, into vitamin D. However, cooking mushrooms in fat can cause vitamin D to leach out as it is fat-soluble.
Mushrooms are also a good source of potassium, which is known to reduce the negative impact of sodium on the body and lessen tension in blood vessels, potentially helping to lower blood pressure. They are low in sodium, so using them in recipes that call for saltier ingredients can help reduce sodium intake. They are also a source of B vitamins, including thiamine, riboflavin, B6, and B12.
Mushrooms have been used as medicine for thousands of years, with edible varieties such as maitake and shiitake, and inedible varieties like reishi, being employed for their health benefits. They have anti-inflammatory properties and can stimulate the activity of immune cells, macrophages, and free radicals, which can stop the growth and spread of tumour cells and cause existing tumour cells to die. They also contain polysaccharides, indoles, polyphenols, and carotenoids, which have been shown to have antioxidant, anti-inflammatory, and anticancer effects in cell and animal studies.
The nutritional profiles of mushrooms vary between types, with some being everyday fare and others costly delicacies. However, most provide the same quantities of nutrients per serving, regardless of their shape or size. They are low in calories and fat, and a good source of fibre and protein.
