Does it matter that much? It would vary whether fresh, frozen, canned... so that might be the problem.

The amount of spinach you are measuring may play a factor...

MFP says generic brand raw spinach has ~550mg of K / 100g.

Fresh spinach, raw from USDA shows 558mg. I'd go with that.

This is organic baby spinach, one plastic party cup full (so a cup). and

-nutritiondata.self.com is saying it has NONE. wtf.
-fatsecret.com says 167mg.
-nutrition-and-you.com says 372mg potassium for my cup size. (Source: USDA National Nutrient data base)

I am going with USDA source.

From nutritiondata (based on USDA.gov):

100 g raw spinach = 558 mg
100 g cooked spinach (1/2 cup) = 466 mg...and this is only about 10% of RDA (Recommended Daily Allowance).

Spinach may be OK, it's also high in iron, but there are fruits, rather than vegetables, that are high in potassium. A good vegetable source are potatoes.

Tomato paste rocks on the potassium count!
330mg in just 2 tbsp (30g)

I never realized how much potassium you need daily. Its crazy. I was getting basically none for so long.

That RDA recommendation is actually crazy high - I personally think it's exaggerated. You really need to struggle to get that amount (4 grams) per day every day.
