Potassium is a critical electrolyte that’s essential for the regulation of fluids, conduction of nerve signals and regulating muscle contractions. Here’s how Potassium does all of that:
Here a list of Potassium-rich foods you need to include in your diet.
Beans and lentils are rich sources of Potassium. White beans contain 829mg of Potassium per cup (179g), which is about 22 percent of the RDI (Recommended Daily Intake). One review involving about 250,000 people showed that increasing dietary Potassium intake by 1640 mg, which is about 45 percent of the RDI every day, cut down the risk of stroke by 21 percent. White beans are also rich in other essential nutrients such as Folate, Thiamine, Magnesium, Iron and Manganese, along with containing plenty of fibre.

Spinach also has 4 times the RDI of Vitamin A, 30 percent RDI of Calcium, ten times the RDI of vitamin K and 90 percent RDI of Manganese. All of these essential nutrients aid in good vision, bone health, metabolism and immunity.
This red root vegetable with its sweet flavour makes for a tasty addition to your salad while giving you about 518 mg of Potassium per cup ( 170 g) which is 13% of the RDI.

One glass (240 g) of coconut water contains 600 mg of potassium, which is about 15% of the RDI. It is excellent for rehydrating the body after going out on a hot summer day or high-intensity workout. Studies have found that it is more effective than plain water and just as effective as sports drinks at rehydrating the body.
Dry fruits and nuts are an excellent choice of a nutritious snack that’s high in Potassium. Dried apricots are a great source of Potassium that will also satisfy your sugar craving while adding a number of other essential nutrients, along with fibre. When served dry or dehydrated, you also tend to eat more and get about 1500mg of potassium per cup, which is a little more than half the RDI. If you’re not a fan of dried apricots, try dried raisins, peaches or figs, which are also rich sources of potassium. Preferably go for unsweetened and unsalted dry fruits for the maximum benefits.
Although fruits and vegetables are the best sources of Potassium, dairy products are surprisingly high in the mineral. One cup of whole milk contains about 300 mg of Potassium, while the same amount of skimmed milk has 400 mg, which is 11 percent of RDI. Yoghurt, which is a popular probiotic, also contains abundant amounts of Potassium. One cup (245 g) of yoghurt contains 400 mg Potassium and plenty of good bacteria that are essential for the healthy functioning of the gut. When choosing yoghurt, go for the plain variety that is not loaded with flavours or sugars.
Oranges and other citrus fruits are popular for their Vitamin C content. However, they are also excellent sources of Potassium. One glass of orange juice contains about 400 mg of Potassium or 11 percent of the RDI. It is also loaded with Vitamin A, Folate, Thiamine and antioxidants. Orange juice is a refreshing drink on a hot summer day or to replenish electrolytes after a mild workout session. Its high antioxidant content fights free radicals and boosts immunity along with Vitamin C to keep you healthy.
Potatoes have long been part of our diet due to their abundance of every essential vitamin and mineral. They are also one of the densest sources of Potassium among all vegetables. One large (300 g) baked potato has 1275 mg or 34% of the RDI. Although most of the potatoes’ Potassium is in its flesh, the skin contains a third of the mineral. Therefore, eating it whole is the best way to get all of its nutrients. Sweet potatoes also have a significant amount of Potassium in them, along with healthy carbs and fibre. A 180-gram sweet potato can have up to 675 mg of Potassium, which is 18 percent of RDI.
Tomato sauce is not only popular for its taste, but also the range of essential nutrients it has. When it comes to Potassium, a cup (244 g) of tomato sauce has about 638 mg or 17 percent of the RDI. It is also rich in Vitamins A, C, E, B6 and copper. The antioxidant lycopene present abundantly in tomatoes combats free radical damage, fights inflammation, and boosts immunity.
Quite often, Potassium levels are tested for in blood tests when a related illness shows up. Potassium deficiency rarely shows up as isolated symptoms. However, low Potassium can cause muscle cramps, weakness, fatigue, and constipation. The most troublesome complication of low Potassium is heart arrhythmias or irregular heartbeat in people who have heart diseases.
The recommended intake of Potassium by the ICMR is 1100 mg/day for children between 1-3 years, 1550 mg/ day for children between 4 to 6 years, 3225 mg/day for the average woman and 3750 mg/day for the average man.
