A single cup of cooked corn contains approximately 384 milligrams (mg) of potassium. This makes corn a good contributor to your daily potassium intake, an essential mineral for various bodily functions.
Potassium in Corn: A Nutritional Overview
Potassium is a vital electrolyte that plays a crucial role in maintaining fluid balance, nerve signals, and muscle contractions. While often highlighted for its fiber content, corn also provides a notable amount of potassium, especially when consumed in standard serving sizes. The amount can vary slightly depending on the type of corn, preparation method, and specific serving size, but 384 mg per cup of cooked corn is a reliable estimate.
To put corn's potassium content into perspective, here's how it compares to other common potassium-rich foods:
| Food Item | Standard Portion | Potassium (mg) |
|---|---|---|
| Carrots, raw | 1 cup | 410 |
| Black turtle beans, cooked | 1/2 cup | 401 |
| Snow peas, cooked | 1 cup | 384 |
| Corn, cooked | 1 cup | 384 |
As you can see, cooked corn provides a similar amount of potassium per cup as cooked snow peas, and is comparable to a half-cup serving of black turtle beans or a cup of raw carrots.
Why Potassium Matters for Your Health
Potassium is critical for maintaining overall health. It works in conjunction with sodium to help regulate blood pressure, supporting cardiovascular health. Adequate potassium intake can help offset the effects of sodium, which is particularly beneficial for individuals concerned about high blood pressure.
Beyond blood pressure regulation, potassium is involved in:
- Fluid Balance: It helps maintain the proper balance of fluids inside and outside cells.
- Nerve Signals: Essential for transmitting nerve impulses throughout the body.
- Muscle Contractions: Plays a key role in muscle function, including the heart muscle.
- Kidney Function: Supports healthy kidney function in filtering waste products.
For more detailed information on the benefits of potassium, you can consult resources from the National Institutes of Health Office of Dietary Supplements.
