12 Potassium-rich Foods You Should Be Eating

Potassium is an essential dietary mineral that supports muscle, nervous system and brain function, helps transport nutrients to your cells and helps regulate blood pressure (works in opposition to sodium).

The daily recommended intake for potassium, according to the Institute of Medicine, is 4,700mg for an average adult. Unfortunately, most individuals don’t get enough potassium from the foods they consume.

The amount of potassium in your body may be affected by diabetes, kidney disease, fluctuating hormone levels, vomiting, or as a side effect of certain medications.

The best way to increase your body’s potassium levels is through your diet; please make sure you consult your healthcare provider or a dietitian before taking any potassium supplement.

The richest sources of potassium are fruits and vegetables, so you may already be getting enough potassium. But if your diet doesn’t include enough veggies and fruits like most western diets, there’s a good chance you could use a bit more of this vital mineral.

Here are some foods that are high in potassium that you can incorporate into your diet.

1. Bananas

Eating Banana

Bananas are widely known to be packed with potassium. One medium banana is filled with 400mg of potassium – equivalent to 8.5% of your RDI for this vital mineral.

It also packs a punch with other vital nutrients like B vitamins, about 100 calories and three grams of fibre.

2. Avocados

Types of Avocados

There’s a reason avocados are becoming increasingly popular in recent times. Apart from being an excellent source of healthy fats, avocados also contain folate and vitamin K.

Just a100 grams of avocados (one half) provides about 487 milligrams of potassium, equivalent to 10% of your RI. So, eating a whole avocado will give you 20% of your required intake at once.

Plus, people with high blood pressure who are always told to reduce their sodium intake and increase their intake of potassium are advised to eat lots of avocados. One half of this fruit only contains 0.5& (7mg) of your required daily amount of sodium.

This advice originated from a study known as Dietary Approaches to Stop Hypertension (DASH).

3. Sweet potatoes

Sweet Potato

These sweet spuds are another great way of incorporating more potassium into your diet.

One medium-sized sweet potato is packed with 12% (541 mg) of your required daily amount of potassium, plus, over 500 mg of your vitamin A required intake.

Sweet potatoes are also an excellent source of B vitamins and minerals like copper and manganese. They pack around 4 grams of fibre but only 100 calories.

4. White beans

The term white beans refer to Lima beans, navy (pea) beans, great northern beans, or cannellini (white kidney) beans.

What’s more, one cup is also packed with 28-61& of various B vitamins’ RI. Plus, white beans are an excellent source of plant-based protein and iron, and almost 19 grams of fibre per cup.

Due to their versatility, white beans can be easily incorporated into your diet, for example, as an ingredient for stews or salads. They can also be purchased online.

5. Watermelon

8. Clams


Clams are mostly known for their high zinc content (15% of the DV), a mineral that’s an essential component of many chemical reaction processes in the body.

But clams are also packed with potassium, with three ounces containing 11% of your daily value for the essential mineral – around 530 milligrams.
