Spinach

Anticancer. Anti-inflammatory. A nutritional powerhouse forever immortalized by a certain cartoon sailor with overly developed forearms... Spinach has been shown to slow the growth of ovarian, stomach, and prostate cancer. It’s a rich source of magnesium, which could benefit people who experience headaches because of not getting enough magnesium in their diet. Animal studies also suggest that spinach can prevent or delay the onset of certain type of dementia.
