Directions: Examine the nutrition label of the food you have chosen. Based on the information on the label, your book, and your knowledge of biology, answer the following questions.
- What is your food?
Honey Nut Cheerios.
- What are the nutrients your body needs in the greatest amounts?
Macronutrients, such as fat, water, carbs, protein.
- What nutrients are essential but required in small amounts?
Micronutrients, such as nitrogen and potassium.
- What nutrients are intended to be consumed at a lower level than the daily allowance?
Certain vitamins, cholesterol, fats
- Why are they required in lower amounts? Are they required at all? And if so for what?
Because our bodies already make a sufficient amount of these things. We do need vitamins, but most of them our bodies will already produce, like vitamin D.
- Which organic compounds in your food item provide you with energy?
Carbohydrates, sodium, and some protein.
- Below is a table showing the amount of calories burned per hour playing competitive soccer by people who weigh 130, 155 and 190 pounds.
|Activity||130 lbs||155 lbs||190 lbs|
|Competitive Soccer||295 Calories per Hour||352 Calories per Hour||431 Calories per Hour|
Based on the information above, how long (what percent of an hour) could two servings of your food power you to play competitive soccer? To do this, divide the number of calories in 2 servings of your food by the number of calories burned per hour for someone with your weight. Use the information that is closest to your weight. Show your work.
- Is your food good for your heart? In your explanation, consider if your food is high in saturated fats and cholesterol. In general, less than 5% of your daily value is low and more than 20% is high. See if you can determine other factors in this food that make it heart healthy or not.
My food is good for you. Cheerios have no cholesterol
- Name three roles that lipids, such as fats and cholesterol, play in our bodies. (lipids are fats, oils, waxes, and cholesterol) does your food provide lipids?
Three roles lipids play are chemical messengers, they store energy and they help maintain our body temperature.
- There are different categories of fats: saturated, unsaturated, and Trans. Differentiate between these types of fats. Explain how the body uses them and which are the most healthful and why.
- Should fats be limited? Why or why not?
- Although sugar is a good source of energy for your body, the excess sugar in our bodies can cause weight gain. When we have high amounts of sugar in our blood, our bodies have a ready source of energy and don’t need to burn fat for energy. The fat in our food is then stored in our bodies. Doctors recommend that we intake no more than 40 grams of sugar a day to maintain healthy blood sugar levels. The WHO recommends 20g. Based on this, do you believe your food item is high in sugar? Explain your reasoning.
- What is the main role that carbohydrates serve in our bodies? What happens when we over consume carbohydrates? Explain why.
- Fiber, the indigestible cell walls of plant materials, helps your food move more easily through your digestive tract. You need about 25 g of fiber daily. If you ate two servings of your food item, what percent of your daily fiber intake did you receive? Explain your reasoning.
- Many people do not get enough fiber in their diet. What types of foods could you eat to increase your fiber intake?
- Determine how much protein you need in a day. To do this, you multiply 0.36 times your bodyweight in pounds. Based on this, is your food a good source of protein for you? Explain your reasoning. In general remember, less than 5% of your daily value is low and more than 20% is high.
- Name three roles that proteins play in our bodies.
- What are the building blocks of proteins? Where do we get these building blocks?
- Explain how a turkey protein can become a human muscle protein.
- What do you think is the best advice for someone looking to lose weight? What kind of diet plan would be the most useful? (Chapter 15a)
- Is your food a good source of the 4 vitamins listed above? Explain your reasoning.
The body needs a small amount of sodium to help maintain normal blood pressure and normal function of muscles and nerves. Sodium intake is recommended to be less than 3,000 milligrams daily. Too much sodium in your diet can result in water retention and bloating and increased blood pressure.
- Is your food high in sodium? Explain your reasoning. In general remember, less than 5% of your daily value is low and more than 20% is high.
- What nutrient in important in your body, but has not been discussed as part of this activity? Why is this nutrient so important?
- What is your evaluation of your food? Is it healthy? Unhealthy? Marginal? Neutral? Be specific in your analysis. Would you recommend that other people consume it? Would you feed it to a child? Explain all your reasoning.
