1. 1. Food for ThoughtMonday, June 25, 12
2. 2. Back StoryMonday, June 25, 12
3. 3. No!Monday, June 25, 12
4. 4. Fucking DisclaimerMonday, June 25, 12
5. 5. Glycemic Index The glycemic index (GI) is used to measure amount of carbohydrates in a food by testing blood sugar levels The index is based on 0 to 100 Glucose for example is 100 and and a white potato in 90‘s and something like hummus is around 6...Monday, June 25, 12
6. 6. The concept was developed by Dr. David J. Jenkins in 1980 The test takes the average of 10 ppl over a 2 hour period by testing one food at a time And comparing the test against the the reference index of gluclose (100) University of Sydney has one of the largest databases of food GI’s http://www.glycemicindex.com/about.phpMonday, June 25, 12
7. 7. Quality vs Quantity The problem of GI is that it takes in the quality of the carbs but not the quantity For example Watermelon and white rice both have a GI=80 But Watermelon has far less carbs per gram than white rice does.Monday, June 25, 12
8. 8. Glycemic Load (GL=GI/100 * Net Carbs) Net Carbs is carbs per total The Glycemic Load uses what is called net carbs in it’s calculation. For example watermelon is 8g of carbs per/100g White rice is 53g of carbs per/100g Watermelon GL=6 White Rice GL=42Monday, June 25, 12
9. 9. Estimated Glycemic Load There is also another issue with Gylcemic Index Not all foods have been tested Limited dataset,regional,reactions Nutritiondata.com they have created something called an EGL EGL is based on multivariate analysis on the existing glycemic index dataMonday, June 25, 12
10. 10. A predictive method for GI’s Using known GI’s footprint Estimates (EGL) are in black Actual values in Blue http://nutritiondata.self.com/help/estimated-glycemic-loadMonday, June 25, 12
11. 11. What They Say EGL <100 per day (total) GL <10 Low 11-19 Moderate >20 High GI <56 Low GI 56--69 Medium GI >69 High GIMonday, June 25, 12
12. 12. Cellular Inﬂammation Just like burns and bruises Foods can also cause CI (Trans-fats) (Fried foods) Cold water ﬁsh anti-inﬂammatory (Salmon) (Herring)Monday, June 25, 12
13. 13. Determining Inﬂammation The Liver releases proteins/antibodies When CI occurs Nutrition scientists measure the levels of these proteins Another food rating system was created called IFRMonday, June 25, 12
14. 14. Dr. Weils Anti-InﬂammatoryFood PyramidMonday, June 25, 12
15. 15. The IF Rating System Monica Reinagel created the IFR systemThis system measures 20 separate nutrients to come up with an if rating for foods 100g of McDonalds FF’s (-106) and 100g of Atlantic Wild Salmon (+581) The higher numbers are good and the lower numbers are bad http://inﬂammationfactor.com/Monday, June 25, 12
16. 16. What She Say’s 200 or higher Strongly anti-inﬂammatory 101 to 200 Moderately anti-inﬂammatory 0 to 100 Mildly anti-inﬂammatory -1 to -100 Mildly inﬂammatory -101 to 200 Moderately inﬂammatory -201 or lower Strongly inﬂammatoryMonday, June 25, 12
17. 17. Other Interesting Things Nutrient Density is the amount of nutrients per calorie based on FDA recommendations Fullness Factor predicts the satiating effect of the food used for weight loss Protein Quality is based on having all the essential amino acids in the proper proportions.Monday, June 25, 12
18. 18. Monday, June 25, 12
19. 19. Monday, June 25, 12
20. 20. My Super Food Short List • Kale • Spinach • Onions • Garlic • Flaxseeds • Macadamia • Sardines • Salmon • Oranges • StrawberriesMonday, June 25, 12
