Potassium: the mineral most calorie trackers ignore

Most adults track sodium when they think to. Almost no one tracks potassium. The data says we should reverse that prioritization.

The intake gap

The recommended intake for potassium is 3,400mg/day for men and 2,600mg/day for women. The average American eats about 2,300mg/day — 30–50% short of target.

This is not a vitamin-deficiency-disease problem (you won't get scurvy from low potassium), but it's a chronic-disease-risk problem. Sodium-potassium ratio matters more for blood pressure than sodium intake alone, and most Americans are running a 2:1 sodium-to-potassium ratio when the target is closer to 1:2.

The asymmetry: salt is everywhere, potassium isn't

Sodium is in nearly every processed food, restaurant meal, and packaged snack. Avoiding it requires effort. Potassium is concentrated in a small number of foods — most of which require active selection: bananas, potatoes, beans, dairy, leafy greens, fish.

If you're eating mostly packaged or restaurant food, you are almost certainly under-potassium even if you're not actively avoiding it.

The big potassium foods

Per serving:

• Baked potato with skin (medium): 925 mg
• Sweet potato (medium): 540 mg
• Banana: 420 mg
• White beans, 1 cup cooked: 1,190 mg
• Lentils, 1 cup cooked: 730 mg
• Spinach, 1 cup cooked: 840 mg
• Salmon, 6oz: 870 mg
• Yogurt, plain, 1 cup: 580 mg
• Avocado, half: 480 mg
• Edamame, 1 cup shelled: 680 mg
• Coconut water, 1 cup: 600 mg

A single baked potato with the skin gets you 27% of your daily target. Two potatoes a week is meaningful.

Why this matters

Blood pressure. Higher potassium intake is consistently associated with lower blood pressure, especially in people on a high-sodium diet. The DASH diet (the gold standard for hypertension) is essentially "low sodium + high potassium."

Stroke risk. Meta-analyses link higher potassium to ~20% lower stroke risk.

Bone density. Potassium intake correlates with better calcium retention and bone mineral density.

Muscle cramps. Low potassium contributes to cramps in athletes, especially in heat.

How to fix it without overhauling your diet

Add one potassium-rich food to two meals a day. Examples:

• Add a banana to breakfast: +420mg
• Add a cup of beans to your lunch salad: +1,190mg
• Add a sweet potato side to dinner: +540mg

Total: +2,150mg, which closes the gap entirely.

What about supplements

Don't supplement potassium without medical supervision. Acute overdose is rare from food but possible from supplements, especially for people on ACE inhibitors or with kidney disease. The OTC limit (99mg per pill) exists for a reason.

Real food is the right vehicle here.

What to track

In CalorieScan, turn on potassium in the macros panel. Aim for the 3,400mg / 2,600mg target across a rolling 7-day average. You don't need to hit it every day; you do need a weekly average that's not 1,800mg.

If you've been tracking for months and never looked at your potassium average, look at it tonight. The number will probably surprise you.

Sodium is the loud one. Potassium is the one your blood pressure is begging for.
