How much potassium is in sweet potatoes?

One medium sweet potato that has been baked with skin in the oven provides you with around 541 mg of potassium. 

This is way more than the standard recommended serving for a low-potassium food. Because of that, eating too many sweet potatoes on a low-potassium diet is not a good idea. 

On the other hand, if your goal is to have more potassium in your diet, sweet potatoes can help you do just that. As always, it all depends on your dietary requirements and needs.

If you want to consume less potassium from sweet potatoes, you can try eating them without skin.

This reduces how much potassium is in the sweet potato you eat. Unfortunately, it also removes many nutrients, as most of them are found underneath the skin. 

So, the way you prepare and eat your sweet potatoes depends on your dietary requirements.

Are sweet potatoes good for you?

Most calories in sweet potatoes come from carbohydrates, including fiber. This nutrient helps soak up excess stomach acid, preventing acid reflux symptoms. 

Fiber also feeds the ‘good’ gut bacteria in your stomach, which helps keep your digestive tract healthy and working properly. 

A diet high in fiber-rich foods may also aid in weight loss since this type of carb keeps you full and satisfied, which prevents overeating.

Sweet potatoes are also loaded with plant compounds and antioxidants that have anti-cancer properties. 

Studies show that sweet potatoes contain anthocyanins, which are a group of antioxidants that slow the growth of cancerous cells in your bladder, colon, stomach, and breasts. 

As a result, eating a lot of foods high in antioxidants is important for your health and wellbeing.

In addition, one particularly important antioxidant found in sweet potatoes called beta-carotene helps keep your eyes healthy.

In fact, a single serving of mashed sweet potatoes provides you with over seven times the amount of this antioxidant you need per day. 

Beta-carotene is turned into vitamin A in your body, which helps keep your eyes healthy. It also prevents eye damage, which lowers your risk of many eye issues, especially those related to age.

Thanks to the powerful plant compounds found in sweet potatoes, eating them can also help boost your immune system

The antioxidants, vitamins, and minerals that they provide you with all strengthen your immune system. 

This is especially important during colder months and flu seasons, as your immunity might be compromised. 

The same nutrients also help your body fight off inflammation, viruses, and bacteria that cause serious health issues. So, eating even small amounts of sweet potato can help you.
