9. Rhubarb Leaves
Rhubarb stalks are very nutritious, don’t get me wrong. The stalks start as light pink and ends up to be deep red. You are to eat the stalks and not the leaves. The leaves, on the other hand, are not edible. It may look like green leafy veggies which are great for salads but don’t let it’s green exterior fool you. The leaves are composed of Oxalic acid. It can promote formation of kidney stones, to say the least. Plus, if you consume at least 4 to 5 kilos of Rhubarb leaves, you are seriously going to die. No joke.
