  1. Should crops go on the top or bottom of the hill? Which direction should the rows of crops go? Should the house go above/ below/ on side the barn? How close to the river should the barn be? Where should a well go? • What is the best placement for each of these on farmland located on a hillside with a river at the bottom? • Draw a 2 minute sketch: • house • barn • well • corn crop • soybean crop

  2. Let’s stop for 5 minutes as you draw a sketch on the back of your notesheet

  3. soybeans to stop run-off from corn contouring from side-to-side strips of crops House on hill in trees well away from run-off Corn on top of hill to block wind barn above river, but not above well

  4. highlights of unit so far: • scientific method • classification of soils • environmental food production • pH scale What’s up with this spastic banana?

  5. Remember that alkaline means BASIC • As the pH value increases by 1, the substance is 10 times less acidic or 10 times more basic • How much more basic is 12 than 10? 10 (thumb up) 20 (thumb sideways) 100 (thumb down) 40 (fist)

  6. Reminders: • Check the moodle for any missed notes and view the schedule for lab questions. • Due in SG:

  7. Wanted: Spastic Banana Description: 4’ tall, yellow Attention, Students in room 312 There has been an escape!

  8. http://www.beyonddiet.com/l/bd-bv?utm_source=google&utm_medium=cpc&utm_campaign=ads_broads-us-banners&food=blueberry&utm_content=bdedge-bv_vs_bd-bv^bd-bv&gclid=CNmW74nI37gCFck7Mgodg3MABwhttp://www.beyonddiet.com/l/bd-bv?utm_source=google&utm_medium=cpc&utm_campaign=ads_broads-us-banners&food=blueberry&utm_content=bdedge-bv_vs_bd-bv^bd-bv&gclid=CNmW74nI37gCFck7Mgodg3MABw 5 foods not to eat Food and Nutrition October ?? 2013

  9. Now there are 2… What’s going on?

  10. Outline • Food pyramid - plate • Essential nutrients and minerals • Food labels You Are What You Eat.

  11. This was the US food pyramid until June 2011 vegetables fruits grains milk meat & beans fats

  12. Some think it is more like this…

  13. As of June 2011…you will have to report to this site for personal recommended facts in SG this weekWhen you get there choose:BMI calculator Why does this banana get all the promo time? I don’t know, but I am a stage worthy peach… It’s not fair! http://myplate.gov/weight-management-calories.html

  14. Take out your print-off from the 6’s. • You will use this info for lab 1 next week How does the BMI from My Plate compare to the BMI you found in the phet simulation from lab for a 25 year old? Check your data.

  15. 2000 calorie diet with moderate exercise: Whole Grains It says “moderate”… that dude is spastic! *8 fl. ounces = 1 cup

  16. What does this mean? • 50 tsp in 1 cup = • 5g per tsp = • 250g per cup • Your lab makes you calculate the calories based on grams per major energy source – since each of these food groups contains multiple caloric breakdowns of the energy sources. ½ to ¾ of a cup • grains= • vegetables= • fruits= • dairy= • meat + beans= 2 ½ c ¾ c

  17. Do you have to be so spastic? He is beyond spastic! Get out of my space.. Just ‘cuz’ you’re yellow, doesn’t mean we are related!

  18. *Table shows the number of calories needed per day. *There seems to be a theme with this banana!! SEDENTARY = < 30 min/day MOD. ACTIVE = 30 – 60min/day ACTIVE = 60+ min /day

  19. One ‘regular’ chocolate chip cookie averages 100 calories. You would need to eat 35 of these to gain a pound… *1 pound = 3500 calories One extra 500 calorie Big Mac or giant sandwich for a week = One pound

  20. If there are 5g in one teaspoon and 50 teaspoons in a cup, how many grams are in one cup? 1 tsp = about 5 gram Is your spoon too big? 250g = 1 cup

  21. FOR THE NEXT SEVERAL SLIDES: -headings are in BURGUNDY -definitions will be in RED and -examples will be in GREY -RDA % and amount for a 2000 cal diet are in BLUE and calories per gram are in GREEN NOTES:

  22. 6 Essential Nutrients:molecules required as intake -not made by your body • Carbohydrates = 4 Calories per gram • Fats = 9 Calories per gram • Proteins = 4 Calories per gram • Water • Vitamins • Minerals

  23. 1. Carbohydrates • “Ready Energy” • Body’s main source of energy • Sugars and starches (BREAD, POTAOES, FRUITS–N–VEGGIES) -dark orange Iodine Test for starch when it turns black -Benedict’s Blue solution for sugar when it turns green, yellow or orange.

  24. …IT’S TIME FOR TIMER Nutritious Dishes - banana • 60% of energy intake = 1200cal • 4 calories/gram

  25. 2. Fats • “Stored energy” • Insulates body from cold • Cushions organs and bones • Transports some vitamins (A, D, E, K)

  26. < 25% of calorie intake, 30% max. = 600cal • 9 calories/gram (highest)

  27. Types of Fat • Saturated • Animal fat (BUTTER) • Solids at room temperature • Not that good for you (always debated) • Unsaturated OIL

  28. Types of Fat • Saturated • Unsaturated • Plant fats (SEEDS, NUTS, PLANT OILS) • Liquids at room temperature • Not too bad in moderate amounts OIL

  29. Here is an interesting fact: • Food labels in U.S. list total amount fat=5 g in the ex. • What about trans fats? • the discrepancy • 2g =trans fat. • What % is this?

  30. Here is another interesting fact: • Notice that the total carbohydrates. The fiber and sugars don’t add up. • The missing amount is starch. • the discrepancy • 17g =starch. • Is this good or bad?

  31. 3. Proteins • Materials for building & repairing muscle tissues = made of subunits called amino acids which cannot be made in our bodies and must be found in our diet • Can be used for energy if no carbs or fat … IT’S TIME FOR TIMER ON CHEESE!!

  32. 10% of calorie intake = 200cal • 4 calories/gram

  33. Protein - illness • Too much protein in the diet puts a strain on the kidneys • Not enough protein in the diet leads to Kwashiokor’s disease

  34. 4. Water • Carries nutrients to cells • Helps eliminate waste • Regulates body temperature • 50-55% of total body weight • No calories per gram

  35. Water-illness • ¾ of all Americans are chronically dehydrated • Thirst mechanism can be so weak that it can be mistaken for hunger

  36. Review: • What is the recommended % calorie input of carbohydrates? • 60% • What is the recommended % for protein? • 10-15% • What is left for fats? • 25-30% maximum

  37. Here are facts on M… How about a shake vs. a flurry? How about a small vs. large fry? How many calories in a flurry are fat if there are 9 calories per gram in fat? What % of the total is this?

  38. Here are facts on M… 2. How many calories in a Big Mac are fatif there are 9 calories per gram? What % of the total is this?

  39. Here are facts on M… How many calories in a Large Fry are fat if there are 9 calories per gram? What % of the total is this?

  40. Here are facts on M… Should you have 37% of your calories from fat? 4. Add up all the fat calories from this meal. WOW! 210 + 290 + 230 = 730 calories of fat = 37% of 2000 total per day

  41. 5. Vitamins • Organic (carbon containing) molecules (chemicals)acting as catalysts to help body reactions occur with less energy in less time.

  42. Vitamins • 13 essential vitamins • Lack of vitamins → deficiency diseases • A,D, E, K =fat soluble • too much  toxic • Vitamin C & B complex =water soluble • no max

  43. Vitamin C • Vital to the production of collagen. • Collagen is the most abundant of the fibers contained in connective tissue.

  44. Vitamin C deficiency → scurvy • Eat fruits: oranges, lemons, limes, grapefruit Scurvy is a disease resulting from a deficiency of vitamin C. Timer has a fun Vitamin C snack

  45. Vitamin A • Essential for good health —notably for eyes and skin, immune function, reproduction, and bone growth

  46. Vitamin A deficiency → night blindness • Eat carrots, red peppers, pumpkin Vitamin A deficiency (VAD) is the leading cause of preventable blindness in children and increases the risk of disease and death from severe infections.

  47. Vitamin K • used in the body to control blood clotting and is essential for synthesizing the liver protein that controls the clotting.

  48. Vitamin K deficiency → poor blood clotting • Eat broccoli, spinach, milk Vitamin K deficiency causes bleeding disorders, fractures, osteoporosis and many other health conditions.

  49. Vitamin D • Aids in the absorption of calcium, helping to form and maintain strong bones.

  50. Lack of vitamins → deficiency diseases Vitamin D deficiency → rickets • Drink milk and sit in the sun Rickets is a disorder caused by a lack of vitamin D, calcium, or phosphate. It leads to softening and weakening of the bones.
