Hypothesis
Does varying levels of omega-3 fatty acids in diet affect leukocyte numbers and function?
Conclusion
Regular consumption of omega-3 enriched foods leads to lower natural killer cell numbers and increased lymphotoxin production, suggesting a reduced inflammatory response.
Supporting Evidence
- Erythrocyte omega-3 levels were higher in subjects consuming n-3 enriched foods.
- Natural killer cell numbers were lower in n-3 supplemented subjects.
- Higher n-3 levels correlated with increased lymphotoxin production.
- No significant changes in neutrophil, monocyte, T cell, or B cell numbers were observed.
Takeaway
Eating foods with omega-3 can lower certain immune cells that cause inflammation, which might help people with inflammatory diseases.
Methodology
A double-blind, placebo-controlled study where 44 healthy subjects consumed either standard or omega-3 enriched foods for six months.
Potential Biases
Potential bias in self-reported dietary intake and compliance with food consumption.
Limitations
Some samples were not viable or lost, affecting the total sample size.
Participant Demographics
Healthy non-smoking volunteers aged 20 to 65 years, overweight with specific health criteria.
