Understanding Nutrition Labels
Nutrition labels are found on most packaged foods and provide important information about the nutritional content of the food.
Nutrition labels provide information about the serving size, calories, and nutrient content of the food. They also include information about the amounts of nutrients such as fat, cholesterol, sodium, and protein. Additionally, nutrition labels often include information about the percent daily value (%DV) of each nutrient, which can help you determine if a food is high or low in a particular nutrient.
One important aspect of nutrition labels is the serving size. The serving size is the amount of food that is considered one serving and is used to calculate the nutrient content and calories of the food. The serving size is typically listed in a standard measurement such as cups or ounces, making it easy to compare similar foods.
It’s important to note that the serving size listed on the nutrition label may not be the same as the amount of food that you actually consume. For example, if the serving size for a bag of chips is 1 ounce (28 grams) and you consume 2 ounces (56 grams), you’ll need to double the nutrient content and calories listed on the label.
