Question

reading food labels
learning to read food labels will help you choose more healthful foods. food labels contain information about the amount of fat and calories per serving, and the nutritional value of the food in relation to the recommended total daily diet. food labels also tell you how many servings there are in the container and how large each serving is. the percent daily values are based on a daily diet of either 2,000 or 2,500 calories. you can decide whether or not to eat the food based on your daily calorie goals and the percent daily values of fat, sodium, and other nutrients.

1. if a person ate all the food in this container, how many servings and calories would he or she consume?

1. what percent of the total fat in this food is saturated fat?
2. what percent daily value of vitamin c is in this food?
3. is this food a source of dietary fiber?
4. how much protein is there in three servings of this food?

food labels list ingredients in decreasing order by quantity. for example, if flour is listed first, this means there is more flour in the food than any other ingredient. some labels list sugar in its various forms (sucrose, fructose, and/or glucose). this can make it look like the product contains less sugar than it actually does.
ingredients: whole wheat, wheat bran, sucrose, high fructose corn syrup, salt, malt syrup, annatto, turmeric, ascorbic acid (vitamin c), reduced iron, alpha tocopherol acetate (vitamin e), niacinamide (niacin), zinc oxide, vitamin a.

1. which ingredient in the list is present in the largest amount?
2. does this food contain sugar? explain.
3. which ingredient in the list is present in the smallest amount?

Explanation:

Step1: Calculate total calories

Multiply calories per - serving (200) by number of servings (4). So, $200\times4 = 800$.

Step2: Calculate percentage of saturated fat

Divide saturated fat (5g) by total fat (10g) and multiply by 100. $\frac{5}{10}\times100=50\%$.

Step3: Find vitamin C percentage

From the label, vitamin C % daily value is 0%.

Step4: Check dietary - fiber

Dietary fiber per serving is 4g, so it is a source of dietary fiber.

Step5: Calculate protein in 3 servings

Protein per serving is 4g, so for 3 servings, $4\times3 = 12g$.

Step6: Identify most abundant ingredient

Ingredients are listed in decreasing order by quantity, so whole wheat is in the largest amount.

Step7: Check for sugar

Sucrose is a form of sugar and it is listed as an ingredient.

Step8: Identify least abundant ingredient

Ingredients are listed in decreasing order by quantity, and vitamin A is likely the least abundant as it is at the end of the list.

Answer:

1. 800
2. 50%
3. 0%
4. Yes
5. 12g
6. Whole Wheat
7. Yes, because sucrose is listed as an ingredient.
8. Vitamin A
