- Textural Improvement: Affects the texture of baked goods and processed meats.
- Curing Agent: Essential in curing meats like bacon and ham.
1.2. Distinguishing Sodium from Table Salt
Often used interchangeably, sodium and table salt (sodium chloride) are not the same. Sodium is a mineral, whereas table salt is a compound comprising sodium and chloride. 1 teaspoon of table salt contains roughly 2,300 mg of sodium, the daily recommended limit.
2. Common Culprits: Foods High in Sodium
Identifying foods high in sodium is the first step toward managing your intake. Surprising to many, the primary sources of sodium in the average American diet are not from the salt shaker but from processed and packaged foods.
2.1. The Usual Suspects: Processed Foods
Processed foods often contain high levels of sodium, used as a preservative and flavor enhancer. Examples include:
- Canned Goods: Soups, vegetables, and beans often packed in brine.
- Processed Meats: Bacon, ham, sausages, and deli meats.
- Frozen Meals: Entrees and side dishes designed for convenience.
- Snack Foods: Chips, crackers, pretzels, and salted nuts.
- Fast Foods: Burgers, fries, and pizza from fast-food chains.
- Sauces and Condiments: Soy sauce, ketchup, mustard, and salad dressings.
- Ready-to-Eat Cereals: Some breakfast cereals contain significant amounts of sodium.
2.2. Hidden Sodium Sources
Sodium can lurk in unexpected places, making it essential to read nutrition labels carefully:
- Breads and Rolls: Even without tasting salty, these can contribute significantly to sodium intake due to serving sizes.
- Cheese: Some cheeses, particularly processed varieties, are high in sodium.
- Pastries and Sweet Goods: Sodium bicarbonate (baking soda) contains sodium.
- Some Beverages: Electrolyte drinks and certain vegetable juices.
2.3. Sodium Content in Popular Food Categories
| Food Category | Examples | Average Sodium Content (per serving) |
|---|---|---|
