Many health claims about mushroom coffee exist, yet only few well-designed clinical trials with human participants exist to verify whether or not it has positive or negative impacts on people’s health. Studies are underway on medicinal mushrooms to see if they can improve immune health but this research mainly takes place on test tubes or animals – further investigation will need to take place before conclusively showing if these compounds prevent, treat, or cure cancer.

Cancer Research UK reports that human and mouse studies indicate reishi mushroom extract may starve cancer cells by interfering with their ability to utilize glucose. Cancer cells do not convert ketones to energy as normal cells do, therefore using glucose for fuel. Reishi may thus help stop the growth of ER+ inflammatory breast cancer (IBC), with benefits also seen among women who have had no mastectomy yet who still face risk from this form of the disease; mastectomy alone might not suffice in such cases.

Numerous studies have linked higher mushroom consumption with lower risk of overall and site-specific cancers. This may be related to fungi such as turkey tail mushrooms being known to contain natural anticancer compounds and immune-modulating proteins that could provide antimicrobial, antidiabetic, cardiovascular protective, and hepatoprotective benefits.

A meta-analysis found that higher mushroom consumption was linked to reduced risks of breast cancer. This may be related to antioxidants ergothioneine and glutathione which are known to protect cells against carcinogenic damage; however, as these studies were observational in nature it’s possible that other factors contributed as well, including diet or lifestyle choices.

Mushrooms are being studied to see if they can boost immune systems and fight tumors. Turkey tail mushrooms contain polysaccharides known as beta-glucans that may stimulate your immune system and increase white blood cell counts that attack tumors.

Coffee and other caffeine-containing beverages have been linked with an array of diseases. Caffeine acts as a stimulant and may lead to anxiety, rapid heartbeat, dizziness and jitters for some individuals. People who already suffer from heart conditions, high blood pressure or digestive disorders should avoid caffeine altogether.

Mushrooms can generally be eaten safely when consumed in moderation, according to the Cleveland Clinic. However, certain species such as chaga mushrooms contain high concentrations of oxalates that may increase kidney stone risk in people who already have kidney stones or those on a low-oxalate diets. People allergic to mushrooms should avoid them. Furthermore, certain mushroom coffee blends could contain trace amounts of caffeine – for this reason, it’s wiser to opt for brands which list caffeine content per serving for informed decisions when purchasing mushroom coffee blends containing caffeine content per serving in order to make informed decisions regarding diet choices about what might work best.
