Hypothesis

What is the relationship between smoking status and serum and dietary micronutrient concentrations?

Conclusion

Current smoking status affects dietary nutrient intake as well as plasma folate levels.

Supporting Evidence

  • Smokers had lower dietary intake of vitamin C, fiber, and fruits and vegetables.
  • Serum folate levels were lower among smokers compared to non-smokers.
  • Current smoking status was linked to inadequate dietary nutrient intake.

Takeaway

Smokers eat less healthy food and have lower levels of certain vitamins in their blood compared to non-smokers.

Methodology

Cross-sectional study with dietary recalls and blood samples from randomly selected farmers.

Potential Biases

Potential bias due to self-reported dietary intake and smoking status.

Limitations

The study is limited to a specific population of farmers in Crete, which may not be generalizable.

Participant Demographics

502 farmers, 44% male and 56% female, aged 18-79.
