Metabolization: Eating too much spinach may lead to an excessive buildup of gas, bloating, and cramps because our body needs some time to digest the excessive load of spinach and cannot metabolize it all at once.

What leafy greens cause gas?

Kale, broccoli, and cabbage are cruciferous vegetables, which contain raffinose — a sugar that remains undigested until bacteria in your gut ferment it, which produces gas and, in turn, makes you bloat. But don't shun those healthful greens just yet.

Can spinach cause stomach problems?
