Why do US consumers buy organic products? -correct answers To avoid pesticides, for better
health and nutrition, environmental protection, and animal welfare.
Do reasons for buying organic differ by generation? -correct answers Yes—young consumers
focus more on health/sustainability than older consumers who more often cite pesticide
avoidance.
What are non-dietary risks of pesticide use? -correct answers Farmworker exposure, pesticide
drift, groundwater contamination; workers near fields are most at risk.
Which agency tests food for pesticide residues in the US? -correct answers USDA Pesticide Data
Program (PDP).
How are pesticide residues sampled and measured? -correct answers Random retail food
sampling with lab analysis comparing residue levels to tolerances.
What do pesticide residue surveys of non-organic food show? -correct answers Most residues
are below legal limits, but residues are commonly detected.
Are organic foods free of pesticide residues? -correct answers No—residues occur, but less
frequently and at lower levels than conventional foods.
, How do imported and domestic food residue levels compare? -correct answers Imported
produce generally has higher residue detection rates.
How are dietary intervention studies conducted? -correct answers Participants switch from
conventional to organic diets; urine biomarkers measured before and after.
What findings come from dietary intervention studies? -correct answers Pesticide biomarker
levels drop significantly after switching to an organic diet.
What happens to pesticides after application? -correct answers Some break down quickly,
others persist in soil and environment beyond the growing season.
What is the trend in pesticide use over the last 10 years? -correct answers Lower total pounds
for some pesticides, but newer ones are more toxic/persistent.
Which insecticide has the biggest usage increase and risk? -correct answers Neonicotinoids;
harmful to bees, pollinators, and biodiversity.
What plant compounds are higher in organic crops? -correct answers Phenolics and antioxidants
due to higher stress and lower synthetic nitrogen.
What types of studies compare organic vs conventional nutrition? -correct answers Field trials,
lab analyses, meta-analyses; results vary by crop, soil, weather, storage.
What are the nutrition differences in pasture-raised livestock? -correct answers Higher omega-3
fatty acids, CLA, and some vitamins.
Do organic foods differ nutritionally according to meta-analyses? -correct answers Yes—small
but significant differences in antioxidants and fatty acid profiles.
