There's a dark side to spinach you should know about

Staff writer

Spinach is a healthy plant to eat - but too much of it can have bad side effects.

They include:

1. Poor mineral absorption

2. Coarse teeth

3. Stomach disorders

4. Anemia

5. Kidney strones

Watch our video, above, for more information on these side effects.

There doesn't appear to be any official guidance on the recommended daily intake of spinach - so everything in moderation, as they say.
