Poop-o-meter
NOPE.
Consulting the colon…
Do cashews make you poop?
Nope, not a normal handful. Cashews are loaded with magnesium, but magnesium from food doesn't have the laxative kick of a supplement. A handful also has less than 1 g of fiber.
Strength Weak
Magnesium 83 mg an ounce
Fiber under 1 g
Did cashews make you go?
The meter says what should happen. Your bowels get a vote too.
Why it doesn't
Food magnesium doesn't send you running
An ounce of cashews has about 83 mg of magnesium. NIH says magnesium from food isn't a problem for healthy people because the kidneys get rid of the extra. The 350 mg limit only counts supplements and medicines.
Not much fiber
An ounce has about 0.9 g of fiber, so cashews don't add much bulk.
Mostly fat
That ounce is about 12 g of fat. Our meter gives fat a small nudge, nowhere near enough to move the needle.
