For many, reading food labels takes time and perseverance.

Here’s a helpful idea called the 5/20 rule. It helps you quickly decide which foods have a lot — or not — of nutrients. If a nutrient meets 20 percent or more of your daily value, that’s generally a lot. If a nutrient has 5 percent or less of your daily value, that’s pretty low. The daily values, by the way, are based on a 2,000-calorie diet. If you’re trying to eat fewer than 2,000 calories, you’ll have to adjust the percentages downward.

If you’re looking to boost your calcium intake but minimize sugars, look for a product with 20 percent of your daily value of calcium and less than 5 percent of your daily value of added sugars. This also works really well for lowering sodium. If a product has less than 5 percent of your daily value of sodium, you know it’s a low-sodium product.

One other thing: Be sure to observe the serving size. If the serving size is for one person, the numbers are good, but if it serves two and you plan to eat the whole thing, you’ll need to multiply the numbers by two — and that will increase the percentage.

For healthy eating, it’s important to pay attention to the numbers on the label that pertain to your health goals. For most Americans, those goals include boosting fiber, potassium, calcium and vitamin D and limiting added sugars and saturated fats.

The bottom line? The back of the package may be more helpful than the trendy buzzwords on the front, boasting “free from…,” “natural” or “improved.” Those aren’t universally defined. Remember no single food is meant to provide everything you need, but long-term healthy food choices can make a big difference.
