I Tried Eating Mushrooms Every Day for a Week Aleksandr Zubkov – Getty Images
Mushrooms tend to be divisive among food lovers. Some people steer clear of them entirely, while others are passionate fans. As a dietitian, I’m firmly in the latter group. Their rich, earthy flavor and remarkable versatility enhance a variety of dishes—from savory breakfast oats and hearty tacos to burgers made with a mix of meat and chopped mushrooms. When my editor proposed a week-long challenge to incorporate mushrooms into my daily diet, I eagerly accepted. Not only would I indulge in one of my favorite ingredients, but I’d also have a handy excuse for my husband—a dedicated mushroom skeptic—when he voiced his disapproval. Here’s what I learned during my seven-day mushroom journey.
What happened when I ate mushrooms every day for a week
My week-long mushroom adventure was nothing short of delightful (at least for me; my husband had a different experience). I felt energized, my digestion was smooth, and my meals were deeply satisfying, bolstered by the mushrooms’ umami richness.
While I didn’t observe any drastic or immediate changes, this is understandable. Many of the most notable health benefits associated with mushrooms, such as cancer risk reduction and protection against Alzheimer’s, take time to manifest and are best realized through consistent, long-term consumption rather than over a mere week.
One unexpected outcome was a decrease in my overall protein intake. Due to mushrooms’ meaty texture, I found myself naturally replacing some meat with them on my plate. While reducing meat consumption can be beneficial, mushrooms don’t provide the same protein levels as beef or chicken. Upon realizing this mid-week, I made a conscious effort to incorporate other protein sources, such as beans, lentils, or Greek yogurt, to bridge the gap.
Mushroom nutrition
Nutritionally, mushrooms are remarkably beneficial, providing a wealth of essential nutrients while remaining low in calories and fat. According to the United States Department of Agriculture (USDA), a standard one-cup serving of raw, sliced white button mushrooms offers:
- Low in calories
- Contains B vitamins
- Rich in selenium
- Sources of antioxidants
- Packed with fiber
- Contains unique compounds
In addition to these basics, mushrooms showcase unique compounds such as beta-glucans, a type of soluble dietary fiber that supports heart health and helps maintain balanced blood sugar levels. They are also a noteworthy source of antioxidants that protect cells from damage, along with providing a rare dietary source of vitamin D.
Benefits of eating mushrooms
Supports brain health
Research indicates that mushrooms might do more than add flavor to your meals; they could also be beneficial for brain health as you age. An analysis of U.S. adults aged 60 and older found that participants consuming higher quantities of mushrooms performed better on cognitive assessments, including tests of memory and processing speed. Although this data indicates an association rather than a direct causation, the prospects are encouraging. Furthermore, a study involving over 600 older adults in Singapore found a significant correlation between higher mushroom intake and a reduced risk of mild cognitive impairment.
The key may be ergothioneine, or ERGO. This amino acid is currently under scrutiny for its potential role in brain health, as lower ERGO levels in the blood are linked to the severity of cognitive conditions. Some researchers suggest that the typical American diet may lack adequate ERGO, a nutrient that helps safeguard against age-related cognitive decline. Fortunately, mushrooms are among the top food sources of ERGO, with varieties like shiitake, oyster, king trumpet, and lion’s mane being particularly rich in this beneficial compound.
Strengthens bones
When considering bone health, dairy products typically come to mind. However, mushrooms hold a unique advantage: they are a natural source of vitamin D found in the produce section. Similar to humans, mushrooms can synthesize vitamin D when exposed to ultraviolet light. Some commercial growers even subject their crops to additional UV light to enhance their vitamin D content.
This vitamin is vital for your body as it aids in calcium absorption. A lack of vitamin D can lead to weaker bones. Regular consumption of mushrooms offers a natural, plant-based option to increase your vitamin D intake, supporting bone density and reinforcing your skeletal health over time.
Nourish your gut microbiome
A thriving gut is critical to overall wellness, and mushrooms provide excellent nourishment for your digestive system. They contain specific carbohydrates, including beta-glucans, acting as prebiotics. These prebiotics traverse the digestive tract without being digested until they reach the colon, where they feed beneficial gut bacteria.
When beneficial bacteria flourish, they produce short-chain fatty acids that reduce inflammation and fortify your intestinal lining. They also bolster your immune system (more on that below).
Support immune defense
Your immune system needs a steady supply of various vitamins and minerals to fend off infections. Mushrooms are an excellent source of micronutrients that help maintain robust defenses. They are particularly rich in selenium, an essential mineral that serves as a potent antioxidant. Selenium helps shield your body’s cells from oxidative stress and is crucial for proper immune function.
Along with selenium, the beta-glucans in mushrooms actively engage with your immune system, stimulating the function of certain immune cells, like macrophages and natural killer cells, enhancing their efficiency in identifying and eliminating harmful invaders.
Who should avoid mushrooms?
While mushrooms offer numerous health benefits, they are not suitable for everyone. Individuals with mushroom allergies need to avoid them entirely to prevent serious reactions. Additionally, certain types of raw mushrooms may cause digestive discomfort for some individuals, so thorough cooking is advisable. If you have specific kidney conditions or follow a restrictive low-potassium diet, consult your healthcare provider or dietitian about how mushrooms fit into your meal plan. Lastly, it’s crucial to never forage for wild mushrooms unless accompanied by a certified expert, as many toxic varieties can resemble safe ones.
The bottom line
My week-long experiment of incorporating mushrooms into my daily diet was not only delicious but also enlightening. From flavorful breakfasts to savory dinners, mushrooms showcased their versatility while contributing significant nutrition to my meals. Beyond their culinary allure, mushrooms present substantial advantages for brain, bone, and gut health, along with boosting your immune system. Whether blended into burgers or tossed in stir-fries, increasing your mushroom intake is a smart and tasty decision.
