Most people are told to eat bananas when looking for potassium-rich foods to add to their diet. If you want to boost your potassium intake, bananas, potatoes, plantains, beans, and sweet potatoes aren’t always the best options. Although these foods contain potassium, they also contain a significant amount of sugar.
One avocado contains 700 mg of potassium, zero starch, and zero net carbs. Avocados are also a potent source of healthy fats and magnesium.
Leafy greens such as Swiss chard and spinach are high in potassium but also high in oxalates. Consuming leafy greens with calcium can help reduce the effects of oxalates.

| 0:00.0 | The number one best potassium-rich food on planet Earth is something I'm going to tell you in just a minute, |
| 0:07.0 | but I first wanted to cover what not to consume as far as foods, which are considered high-potassium foods. |
| 0:14.5 | We have bananas, potatoes, plantains, which, by the way, have more potassium than bananas, beans, and sweet potatoes. |
| 0:22.9 | Every one of these standard recommended foods for increasing your potassium is a starch, |
| 0:29.3 | which means they have a lot of sugar. |
| 0:30.9 | I mean, bananas have like 27 grams of sugar. |
| 0:33.9 | So starch is a hidden sugar. |
| 0:35.2 | No one's going to eat a raw potato, so they're going to cook it. |
| 0:37.7 | So you're basically eating something that's going to turn into sugar very quickly. So yes, they all are loaded with potassium, but they're also loaded with a lot of sugar. Now, beans are loaded with fiber, but they also contain starch, and they do create bloating for a lot of people. Some people can consume them, but some people can't. I can't eat beans without |
| 0:55.7 | getting severe bloating. But there's certain beans that are better than others, but typically beans |
| 0:59.9 | do raise the insulin level. And that's why I put it on the no list. But the number one food |
| 1:05.4 | for potassium is this right here. Avocado. One avocado has about 700 milligrams of potassium. Zero starch. That means |
| 1:16.1 | zero blood sugar spike, zero net carbs, super healthy fats, which slow the digestion, allowing you |
| 1:23.2 | to absorb more potassium. And avocados also are loaded with magnesium that works with potassium |
| 1:30.0 | and allows potassium to work in your body. As compared to eating banana, the digestion is very, very |
| 1:34.8 | quick. So you're going to get this massive blood sugar spike, and then you're going to be hungry |
| 1:39.1 | for another banana in about 20 minutes. But not with avocados. Avocados are super satisfying. They also |
| 1:45.9 | have a lot of other nutrition, including B vitamins and certain minerals. And I eat a lot of avocados |
| 1:50.4 | with my eggs, with meat, I put it on my salad. So a lot of people ask me, what supplements do I |
| 1:56.4 | recommend? Now, of course, I'm not biased of my own high-quality supplement line, but if you go to |
| 2:01.3 | Amazon and type Dr. Berg supplements, you'll find more information. Now, this next one is |
| 2:06.1 | very surprising. Wild salmon has 970 milligrams of potassium. And I'm talking about like a half |
