Navigating the grocery store aisles can be overwhelming, with colorful packaging and marketing claims often obscuring the true nutritional value of a product. However, by focusing on a few key areas of the Nutrition Facts panel, you can quickly assess whether a food aligns with your health goals. The three most important things to pay attention to on a food label are serving information, added sugars, and sodium. Understanding these three components is the foundation of a healthy and informed nutrition diet.
1. Serving Information: The Foundation of the Label
Before analyzing any other numbers, you must first look at the serving information at the top of the Nutrition Facts panel. This section includes the serving size and the servings per container. All other nutritional data on the label—including calories, fats, and carbohydrates—is based on a single serving. This is a critical detail that many people overlook and it can lead to consuming far more calories and unhealthy nutrients than intended.
For example, a package of chips might list a serving size as "1 ounce" and indicate "5 servings per container." If you consume the entire bag, you must multiply all the listed values by five. Ignoring this fact is a common pitfall that can derail dietary plans. The serving size listed is not a recommendation for how much you should eat, but rather a standardized amount to help you compare similar products.
2. Added Sugars: A Sweet Disguise
For a healthy diet, limiting your intake of added sugars is essential. The new Nutrition Facts label separates "Total Sugars" from "Added Sugars," making it easier to identify the sugar content you should be concerned about. Added sugars are those not naturally found in foods like fruit and milk but are added during processing for flavor. Consuming too many added sugars is linked to a higher risk of conditions like type 2 diabetes, obesity, and heart disease.
To identify added sugars, look for them listed as an item under "Total Carbohydrate." The FDA recommends limiting intake to less than 10% of your total daily calories, which is about 50 grams for a 2,000-calorie diet. You should also check the ingredient list for common aliases of sugar, as manufacturers often use many names to hide the true amount. If one of these aliases appears near the top of the ingredient list, the product is likely high in added sugar.
Common Aliases for Added Sugars
- High-fructose corn syrup
- Dextrose and maltose
- Corn sweetener
- Cane sugar
- Fruit juice concentrates
- Sucrose
- Honey, maple syrup, and agave nectar
- Maltodextrin
3. Sodium: An Often-Hidden Health Concern
Excessive sodium intake is a major contributor to high blood pressure, which can increase the risk of heart disease and stroke. The American Heart Association recommends no more than 2,300 milligrams (mg) of sodium per day for most adults, with an ideal limit of no more than 1,500 mg per day. Processed and packaged foods are often the main culprits for high sodium consumption.
Just like with added sugars, you should look for the sodium content listed on the Nutrition Facts panel. The % Daily Value (%DV) is a helpful tool here. Aim for products with a low %DV for sodium, generally 5% or less per serving. A %DV of 20% or more is considered high. You can also scan the ingredient list for sodium's alternative names, such as monosodium glutamate (MSG) or sodium benzoate.
The Importance of the Ingredient List
While the Nutrition Facts panel provides crucial numbers, the ingredient list offers a clear picture of what the product is actually made of. Ingredients are listed in descending order by weight, meaning the first few items make up the largest portion of the food. If you see unhealthy ingredients like sugar, saturated fat, or sodium listed among the first few, it's a clear red flag. A shorter list of recognizable, whole-food ingredients is generally a better choice.
Using the % Daily Value for Comparison
One of the most powerful tools on a food label is the % Daily Value (%DV), which shows how a single serving of a food contributes to your total daily diet based on a 2,000-calorie diet. It helps you make quick, informed comparisons between similar products. As a general guide, remember the "5/20 Rule":
- 5% DV or less indicates a low amount of a nutrient per serving.
- 20% DV or more indicates a high amount of a nutrient per serving.
For nutrients you want to limit, like saturated fat, sodium, and added sugars, look for a lower %DV. For nutrients you want to increase, like fiber, calcium, and vitamin D, look for a higher %DV.
Comparison Table: Cereal A vs. Cereal B
To illustrate how to use these metrics, let's compare two hypothetical cereals. Both boxes might have similar calorie counts on the front but tell a different story inside.
| Feature | Cereal A (Healthy Choice) | Cereal B (Less Healthy) |
|---|---|---|
| Serving Size | 1 cup (40g) | 1 cup (40g) |
| Servings/Container | 12 | 12 |
| Calories/Serving | 150 | 150 |
| Added Sugars | 3g (6% DV) | 15g (30% DV) |
| Sodium | 120mg (5% DV) | 280mg (12% DV) |
| Ingredients | Whole grain oats, dried fruit, nuts | Corn flour, sugar, high fructose corn syrup, salt |
In this comparison, Cereal A is clearly the better choice for a healthy diet, with significantly less added sugar and sodium per serving. This simple comparison highlights why looking beyond just the calories is essential for making nutrient-dense choices.
Conclusion
Understanding what are the three things you should pay the most attention to on a food label—serving information, added sugars, and sodium—is a critical skill for managing your nutrition diet and overall health. By training your eyes to focus on these specific sections, along with the ingredient list and % Daily Value, you can move past deceptive marketing and make truly informed decisions at the grocery store. This simple practice empowers you to choose foods that best support your body's needs and long-term well-being.
