Healthy Snacking & Sustainable Living Web Quest Review
Main Ideas • What nutrients our body needs to be healthy • Recommended daily values for nutrients • Sustainability • Chemistry connections
The Food Pyramid http://www.washingtonpost.com/wp-srv/nation/daily/graphics/diet_042005.html
Nutrients for our Bodies:Carbohydrates • Carbohydrates are sugars • Main supply of energy for your body to function • 1 gram of carb. Gives you 4 calories of energy to use • Examples: fruit, bread, pasta, rice, cereal
Nutrients for Our Bodies: Protein • Made of amino acids (chemicals) • Used to build body tissues, • Help with chemical reactions in your body • Help with transport within your body • Help with immune system • Help keep your body functioning properly
Nutrients for Our Bodies: Protein • Nuts Soy products • Beans • Meats • Fish • Poultry • Eggs • Cheese • Yogurt • Milk http://www.healthline.com/blogs/diet_nutrition/labels/soy.html
Nutrients for Our Bodies: Fat • Chemical compound • Used for energy to fuel the body • Used to store energy • 1 gram of fat has 9 calories • Also used to cushion organs • Your body NEEDS a small amount of fat to function properly
Nutrients for Our Bodies: Fat • Unsaturated fat: “good fat”better for your body • found in vegetable oils, fish, almonds, avocados • Can help lower cholesterol • Saturated fat and trans fat: “bad fat”, not so good for your body • Found in animal products, coconut oil, • Raises cholesterol, can lead to heart problems • Natural trans fat (from dairy and meat) ok in small amounts • Artificial trans fat worse for your body (in snack food, cookies etc)
Nutrients for Our Bodies: Minerals • Another type of chemical needed to help your body function properly • Ex. Sodium • Ex. Chlorine • Ex. Calcium • Ex. Potassium
Nutrients for Our Bodies: Vitamins • Chemical needed to help your body function properly • Helps with chemical reactions in your body • Better to get your vitamins from food than from a pill http://www.nlm.nih.gov/medlineplus/ency/imagepages/18109.htm
Calorie • Food calories are how much energy is in the food you eat
Recommended Daily Value Reference values for nutrition labeling: How much should you get each day? Nutrient Amount for men and women Total fat Less than 65 grams (g) Saturated fat Less than 20 g Trans fat Less than 2 g Cholesterol Less than 300 milligrams (mg) Total carbohydrate At least 130 g Fiber At least 25 g Sodium Between 1,500 and 2,400 mg Potassium At least 4,700 mg http://www.mayoclinic.com/health/food-and-nutrition/AN00284
Organic Foods • Renewable resources used • Soil and water conservation • No antibiotics or hormones, no genetically modified organisms • Only natural pesticides and fertilizers
Added Sugar vs Natural Sugar • Added sugar - refined sugar added to a product during its processing • Ex the sugar in soda, cookies, juice drinks • Natural sugar - sugar found naturally in a substance • Found naturally in fruit, veggies, milk, 100% fruit juice • You want to minimize your added sugar in your diet and sugar in general
Added sugar • Aka: brown sugar, corn syrup, high fructose corn syrup, honey, raw sugar, etc
Sustainability • Using only what you need • Reducing waste • Not depleting a resource • Living in a manner where everyone has enough resources, all the time • http://www.footprintnetwork.org/gfn_sub.php?content=footprint_overview
Biodegradable • Capable of decomposing with the help of bacteria
Styrofoam • Does not break down • Hard to recycle • Alternatives: http://www.worldcentric.org/bio/bagasse.htm • http://www.iaspromotes.com/Categories/SubCategories/Ecofriendly.html • http://www.biodegradablestore.com/product_comp/pp_cold_cups_comp.html • http://www.starchtech.com/cgp/cleangreen.html
Paper vs. Plastic • Both deplete natural resources • Both take lots of resources and take a toll on the environment throughout their life cycles • Better to use a reuseable bag • If you have to use paper or plastic - make sure to reuse and recycle!
Plastic Bottle Life Cycle • Recycled, sorted, shipped to plastic re-claimers, processed and made into other products like clothes, benches, new plastic products • http://www.plasticsinfo.org/s_plasticsinfo/sec_level4_alt.asp?CID=551&DID=3407
