Our Verdict

When comparing leek to onion, we picked the leek.

Why?

In terms of macros, leek has more fiber, carbs, and protein; not by much, but it’s a nominal win for leeks in this category.

In the category of vitamins, leek has more of vitamins A, B1, B2, B3, B5, B6, B7, B9, C, E and K, while onions are not higher in any vitamins; a complete win for leeks here.

Looking at minerals, leek has more calcium, copper, iron, magnesium, manganese, phosphorus, potassium, and selenium, while onions have more zinc; another easy win for leeks.

Adding up the sections makes for a clear overall win for leeks, but by all means enjoy either or both; diversity is good!
