  1. Why do we need it? Food Where does it come from? What should it be?

  2. When your brain is hungry, what does it want you to eat? GLUCOSE!! (from sugary and starchy plants)…..why? Glucose is the fuel that runs your brain and your body. FAT!! (from oily plants and fatty animals)…..why? Fat is a great secondary source of energy as well and is an essential component of your organs, too. SODIUM (from plants and animals)….why? SODIUM (in salt) is an essential mineral that controls nerve signals and muscle movement. COLORFUL PHYTOCHEMICALS (from colorful plants!)….why? Phytochemicals keep your cells running smoothly and your body healthy.

  3. And our brains are wired to crave glucose, fat, color and salt! And we won’t stop the hunt for food until we get…

  4. For your brain to be satisfied, sometimes the work can be hard… …or it can be relatively easy

  5. And our brains are still wired to assume that glucose, fat, color and salt are hard to come by. It’s as if we are still living in paleolithic times!!

  6. Until fairly recently, food was pretty hard to come by. And it still is for many today.

  7. But nature does provide us with food, And here’s how:

  8. The sun is the source of energy for all living things

  9. Plants combine energy from the sun Water (H2O)from the ground or their surroundings And Carbon Dioxide (CO2) from the atmosphere In a process called PHOTOSYNTHESIS

  10. In PHOTOSYNTHESIS, plants make molecules of sugar called GLUCOSE and FRUCTOSE 6 6 6 CO2+ C6H12O6 + H2O = O2 How would you balance that equation? And plants can also make a third, rarer kind of sugar molecule called GALACTOSE

  11. So photosynthesis gives us three basic kinds of sugar… Glucose Fructose Galactose And nature combines these three simplest sugars in a few ways.

  12. Fructose Suc rose Glucose = Lact ose Glucose Galactose = Malt ose = Glucose Glucose

  13. Sometimes plants store their simpler sugars in a compact form known as starch. Glucose STARCH (amylose)

  14. These molecules, all made from carbon, hydrogen and oxygen are called… CARBOHYDRATES Suc Glucose rose STARCH (amylose) Fructose Lact ose Galactose

  15. Just like us, plants need carbohydrates for energy to exist and to grow. Why do lots of plants LOVE IT when we eat the carbohydrates they produce?? But, of course, they can produce their own. We can’t, so we have to eat them.

  16. Many plants we eat contain CARBOHYDRATES like GLUCOSE, FRUCTOSE, SUCROSE and STARCH (amylose) in various proportions

  17. And another form of CARBOHYDRATE called FIBER (cellulose) forms their skins and stems

  18. We can thus eat CARBOHYDRATES in a natural or close-to-natural (“whole foods”) form…

  19. …or we can eat CARBOHYDRATES in a processed, refined form

  20. So which is your better choice and WHY? VS. ????????????????????????????????????????????????

  21. The processing of whole foods often results in the loss of • Vitamins • Minerals • Water • Phytochemicals – colorful “plant chemicals” that are not yet proven as essential nutrients but which may reduce risk of cancer and other diseases.

  22. Whole food vs. empty calories VS. Carbs (sugars, starch, fiber) , water, vitamins, minerals, phytochemicals Carbs (sugars) – and lots of them, which stimulates your reward pathway.

  23. Finally, plants can convert some of the glucose they produce to other forms for storage like FAT PROTEIN

  24. And we can consume FAT and PROTEIN in whole food form…

  25. …or processed form

  26. Remember our brains are programmed to crave glucose and color, among other things… So it can be a tough choice between and

  27. And we’re programmed to also crave fat and salt So is it any wonder that food manufacturers give us

  28. And which is cheaper…? …and why is that???

  29. Processed food is cheap Nutritious food is more expensive So what does that mean if you don’t have much money?

  30. Supermarket chains tend to not locate in low-income areas http://www.activerain.com

  31. Corner Store http://www.kilduffs.com/

  32. Row houses, some abandoned http://www.cityfix.com/

  33. Corner store, abandoned http://www.kilduffs.com/

  34. Abandoned corner store and abandoned row houses http://www.community.livejournal.com

  35. There’s a term for places with little access to nutritious food: So what is a “food swamp”? “food deserts”

  36. A Food Swamp www.hypervocal.com

  37. Food Desert Locator http://www.ers.usda.gov/data/fooddesert/fooddesert.html

  38. http://www.businessweek.com/articles/2012-08-23/food-deserts-of-baltimore#r=lr-fsthttp://www.businessweek.com/articles/2012-08-23/food-deserts-of-baltimore#r=lr-fst

  39. And why does this matter?Here’s one example: http://www.npr.org/blogs/health/2012/11/16/165280637/this-is-how-diabetes-swept-the-nation?utm_source=NPR&utm_medium=facebook&utm_campaign=20121116

  40. The food industry knows how your brain is wired and they know how to get their products to appeal to you.THEY DON’T CARE ABOUT YOUR HEALTH OR WELL-BEING!!!They care about making

  41. Solutions?? You have a choice of three projects at the end of this unit to help solve the problems we’ve just seen. Create a nutritious dish that school students will really want to eat. Or Develop a meaningful solution to the Food Desert/Food Swamp crisis in Baltimore City. Or Redesign the Nutrition Facts label to truly educate consumers.

  42. So Good nutrition is about… What we eat … And when and how… And how much... And how food is prepared… And awareness of how our brains are being manipulated… The next few weeks are about a truth…that will change your lives.
