Understanding food labels is essential knowledge for eating healthily and for making sure that the proper nutrients are available in the food we consume every day. Nearly every packaged food item purchasable in the United States is labeled with the nutritional value by the Food and Drug administration. A few key elements exist to help us understand the nutrition on these labels.
The 5/20 rule determines whether or not a food has a good source of a specific nutrient. If a food has 5 percent or less of a certain nutrient, then that specific food is not considered a good source of the nutrient. If a food has 20 or more percent of a certain …show more content…

Step three and four consist of limiting unhealthy nutrients and eating healthier nutrients. Nutrients to limit are saturated fat, Trans fat, cholesterol and sodium.

Generally the percent daily value is based on a 2,000 a day calorie diet. However, not everyone is on a 2,000 a day calorie diet. It is important to calculate the percent value according to your own personal diet. Step six is the percent daily value. The percent daily value already does the math to calculate how much of a nutrient is present in the food via percentage. In order to understand a healthy percentage of a nutrient listed on the label, simply apply the aforementioned 5/20
