Sales of Organic Fooda. The growth has dropped since the early 2000’s, but it is still growing overall.b. The sales have increased greatly and have reached an overall high.c. Fruit and vegetables are leading the way followed by dairy.d. ~ 10% increase/year in sales II. Geographic Distribution of Certified Organic Producersa. The climate has a very large impact on distribution.b. In the south there is not as many organic distributions because of the pests and animals as well as the climate. III. Organic Practicesa. USDA makes the list of what pesticides are okay to use.b. Organic food is not completely free of all pesticides.c. It is concerned with synthetic materials but not toxic materials.IV. Pesticide residues detecteda. Organic has noticeably lower levels of pesticides than conventional, but they are not absent.These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.b. The reason it is not absent is because of drift and persistent pesticides in environment.c. There is usually less than 1% of exposure to pesticides d. Pesticide residue in food leads to very minimal riskse. There is not current evidence that conventional is more risky than organicV. Organic Food à ¯ non-Hodgkins Lymphoma (1 study)a. 30% of women never ate organic foodb. 63% sometimes ate organic foodc. 7% usually/always ate organic foodd. No relationship with total cancer, but ~20% decrease in risk for non-Hodgkin lymphomae. Some issues with the study: size (is it big enough), is it controlled (they were statistically similar), other diseases, genetic markers, one gender, the question may lead to changes in behavior and they did not follow up throughout the study, and lack of specificity of terms.f. Suggestions: food diary, blood or urine testVI. Nutrition-related health benefits?a. MPD is mean % differences à overall positiveb. Follow the diamondsc. It is statistically insignificant if it crosses over the line.d. None of them enhance nutritional valuee. Pay attention to Vitamins E (higher in conventional) and Cd (heavy in sewage)f. Protein is higher in conventional so it is lower in organicg. Know:i. Antioxidant activityii. Phytochemicalsiii. Flav …. compoundsiv. The well known flavonolsv. Anthyocyaninsvi. Carotenoidsvii.
