Food labeling and Calorie count
Nutritional information, about processed foods, on food label may tell the nutritional value of raw foods used before its preparation. But processing and storage impacts and changes the calorific value of nutrients. For example, whole wheat bread packet may label the nutritional value of whole wheat on its package while the calorific count of wheat post processing changes. Hence, relying solely on food labels as source of nutritional information about processed foods is inaccurate. As much as possible, avoid processed foods and use whole foods for adequate nutrition.
