Should You Drain Canned Corn Before Cooking? Here’s Why It Matters for Your Health

When you buy canned corn at the grocery store, it often comes packed in water. A lot of people simply open the can and pour the whole thing—corn and liquid—straight into the pot. But should you be draining that water out first?

The answer is yes, and it’s more important than you might think, especially from a health standpoint.

What’s in the Liquid?

The liquid inside a can of corn isn’t just plain water. It often contains:

• Salt (sodium)
• Preservatives
• Starches or sugars (depending on the brand)

This liquid is sometimes called “packing liquid,” and it helps preserve the corn and extend its shelf life. However, it can also hold a lot of added sodium—sometimes over 200–300 mg per serving—which can add up quickly.

Why Draining the Water Matters

1. Reduces Excess Sodium

Draining the liquid can cut the sodium content by up to 30% or more.

If you rinse the corn under cold water after draining, you can lower it even further.

Too much sodium in your diet can contribute to:

• High blood pressure
• Heart disease
• Kidney stress
• Water retention and bloating

By draining and rinsing, you’re helping protect your heart and overall health.

2. Improves Taste

The packing liquid can have a slightly metallic or “canned” taste. Draining and rinsing the corn removes that flavor, giving you fresher, sweeter corn that’s closer to the taste of fresh or frozen corn.

3. Reduces Preservatives and Additives

While preservatives are generally recognized as safe, many people prefer to limit their intake when possible. Draining and rinsing canned corn helps wash away excess preservatives, leaving you with a cleaner product.

4. Better Texture for Cooking

Corn cooked in its packing liquid can sometimes get mushy.

When you drain it, you start with firmer kernels, which hold up better in recipes like:

• Corn salads
• Salsas
• Stir-fries
• Soups and chowders

5. Healthier Recipes

If you’re trying to create healthier meals at home—whether for yourself, your family, or even your customers—every small step matters.

Reducing unnecessary sodium and additives from canned goods is a simple but powerful way to improve your overall diet quality.

How to Properly Drain and Rinse Canned Corn

1. Open the can and pour the corn into a colander.
2. Rinse the corn under cold running water for about 30 seconds.
3. Let it drain completely.
4. Now it’s ready to cook or add to your recipe!
