Science Presentation

  1. 1. The Perfect Diet<br />Fabian Fuxa, Lucas El Eter, CaioMaksoud, Frederik Engel<br />
  2. 2. Objective of Presentation<br />Obtain approval from Board of Directors of our proposed new short-term and long-term diets.<br />
  3. 3. Some Interesting Facts<br />63.1% of Americans are either overweight or obese (2009)<br />59.2% of obese Americans exercise at least one day per week. <br />This is a great opportunity for us, Meals on Wheels, to come in and help these obese people who want to lose weight but simply don’t know how.<br />
  4. 4. About Nutrients <br />
  5. 5. What Are They?<br />Nutrients (NOO tree unts) – They are the substances in food that provide the raw materials and energy the body needs to carry out all it’s essential processes.<br />
  6. 6. Types of Nutrients<br />
  7. 7. Carbohydrates <br />Are a major source of energy<br />Provide the raw material to make cell parts<br />Found in pretty much everything: Milk, Watermelons, Bread, Pasta, and many more<br />
  8. 8.
  9. 9. Lipids<br />Lipids (commonly refered as fats) are energy-containing nutrients that are composed of carbon, oxygen, and hydrogen.<br />In addition to providing energy, fats have other important functions. Fats from part of the cell membrane, the structure that forms the boundary of a cell. Fatty tissue protects and supports your internal organs and insulates your body.<br />There are three types of fats:<br />Unsaturated Fats: Healthy<br />Saturated Fats: Unhealthy<br />Trans Fats: Extremely Unhealthy <br />
  10. 10.
  11. 11. Proteins<br />Proteins are nutrients that contain nitrogen as well as carbon, hydrogen, and oxygen<br />Proteins are needed for tissue growth and repair. They also play an important part in chemical reactions within cells.<br />Proteins are made up of amino acids <br />
  12. 12.
  13. 13. Vitamins and Minerals<br />Vitamins <br />Vitamins act as helper molecules in a variety of chemical reactions in the body<br />There are two types of vitamins:<br />Fat soluble vitamins<br />Water soluble vitamins.<br />Minerals <br />Minerals are present in soil and are absorbed by plants through their roots.<br />Both vitamins and minerals are needed by your body in small amounts to carry out chemical processes.<br />
  14. 14.
  15. 15. Water <br />Water is the most important nutrient because the body's vital processes- including chemical reactions such as breakdown of nutrients- take place in water.<br />You need to take in about 2 liters of water per day<br />
  16. 16. Personal Food Categories That Should be Consumed<br />
  17. 17. Menu Analysis<br />
  18. 18. Menu #1<br />
  19. 19. Observations:<br />Contains little if any lipids (fats)<br /> A lot of vitamins and mineral are included in the menu but it doesn´t have many proteins <br />A healthy portion of cabbage soup is given each day for lunch and dinner accompanied with a fruit of vegetable <br />Breakfast is always a fruit or small piece of toast. <br />
  20. 20. Menu #2<br />
  21. 21. Observations:<br />It is a more balanced meal, which includes all nutrients and a variety of different foods.<br />Occasionally has unhealthy foods including some excess of lipids and proteins.<br />Amounts are appropriate and food choices are relatively healthy.<br />Healthy snacks are provided, which is good for a long term diet because eating small amounts of healthy food frequently is healthy for your body.<br />
  22. 22. Menu #3<br />
  23. 23. Observations: <br />Portions are quite big<br />Variety of foods are included, as well as sauces and spices (dressings)<br />Mouthwatering (to most people) and tempting to eat<br />
  24. 24. Conclusions<br />
  25. 25. Menu #3 <br />
  26. 26. Why?<br />An excess of lipids and proteins if present on diet. Examples of such:<br />3 scrambled eggs at breakfast (too much protein)<br />4-6 bacon strips at breakfast (too much fat)<br />12 Buffalo Wings with BBQ Sauce (too much everything!)<br />And many more<br />Portions are too big<br />The little amount of vitamins and minerals (fruits & vegetables) present are ruined because they are covered with unhealthy toppings such as dressing or butter (not even low-fat or low-sugar)<br />
  27. 27. Menu #1<br />Short-Term Diet<br />
  28. 28. Why?<br />Lipids are not present in this diet, which are essential to a diet but don’t have to be consumed every day (you can go a week without it, now that It makes you gain weight)<br />Proteins are also not present in the diet, and just as the lipids, proteins are needed but can be avoided during a week so that you don’t have to absorb so many amino acids in the body.<br />A daily portion of fruits and vegetables are given, since it provides essential vitamins and nutrients, as well as some natural simple sugars (not man-made refined sugar), providing the amount of sugar needed by the body, in a healthy and moderate way.<br />
  29. 29. Menu #2<br />Long-Term Diet<br />
  30. 30. Why?<br />The healthy snacks provided in between meals is good for a long term diet because eating small amounts of healthy food frequently is healthy for your body.<br />The occasional excess of lipids and/or protein can be made now that eating healthy for a long period of time may become boring and the customer may give up on the diet and quit.<br /> The diet is very balanced and contains every nutrient, which is essential for a long-term diet because all nutrients have to be consumed and cannot be avoided for such a long time. <br />
