100% untrue...depends on the lettuce.......yeah Iceberg is total junk...stuff like Romaine and Buttercrunch is very nutritious and and anti-inflammatory which in a day and age where peoples diets are so inflammatory is in itself a virtue for any food.
Of course I will agree...Kale is WICKED and considered a super-food...and that it is.
My personal favorite is sweet potatos.........you can undo a whole day of inflammatory eating with one decent sized sweet potato with some olive oil....or cut into strips as cottage fries with some garlic and cayenne pepper...bring on the ketchup and don't forget a couple of serranos which are also highly anti-inflammatory.
