3. Mushrooms

A study of over 36 thousand Japanese men over several decades has suggested that eating mushrooms can lower the risk of developing prostate cancer, especially for men over the age of 50 . Mushrooms are a good source of vitamins, minerals, and antioxidants, in particular L-ergothioneine, which is believed to mitigate oxidative stress. Oxidative stress is caused by poor diet and lifestyle choices, as well as environmental toxins, that can lead to chronic inflammation and disease .

Another study also found that consuming mushrooms had a preventative effect on breast cancer in women . Medicinal mushrooms, which usually refer to more exotic, specialty mushrooms, have also shown promise in preventing cancer, again because of their glutathione, ergothioneine, and polysaccharide content . Examples of these kinds of mushrooms include reishi, turkey tail, shiitake, and maitake varieties. Studies have found that these fungi affect your body’s antitumor mechanisms, by stimulating certain immune cells . Turkey Tail is particularly notable and contains a unique polysaccharide known as PK (polysaccharide K), a known cancer adjunct therapy for the immune system .
