Make sure your ingredient list on that label has at least five (5) ingredients. Please discuss the answers to the following questions: List the individual ingredients by category (carbohydrate, protein, fat, vitamins, minerals, and additives). Using the information from your textbook, explain the function and relative safety of the identified ingredients. Find a similar organic food item and contrast the ingredients including the food additives to the original product. What did you find in your comparison? What is the relative safety of the organic variation?arrow_forwardBelow is a table of the nutritional information for Jim's takeaway meal. Use this data to complete the table by calculating the energy in kilojoules for the foods in the meal. PLEASE DON'T USE ANY COMMAS IN YOUR ANSWERS. Important tip: the total fat includes saturated fat and carbohydrates include sugars so for the energy from fat you only need to calculate the energy from total fat and NOT from total fat + saturated fat.
