The Claim
Self-reported dairy consumption is significantly higher in Czech Slavs (70.5%) than in Czech Roma (39.0%), and this difference aligns with the population-level frequency of the lactase persistence allele.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Czech Slavs report consuming dairy more often than Czech Roma, and this difference matches the frequency of a genetic variant that allows adults to digest lactose.
See the scientific wording
Self-reported dairy consumption is significantly higher in Czech Slavs (70.5%) than in Czech Roma (39.0%), and this difference aligns with the population-level frequency of the lactase persistence allele, suggesting a correlation between genetic adaptation and dietary behavior.
People who keep producing the enzyme that breaks down milk sugar can digest dairy without discomfort, so they eat it regularly. People who stop producing that enzyme avoid dairy because it causes stomach problems, so they eat less of it.
What the research says
1 studyMost Czech Slavs can digest milk as adults because of their genes, and they also report eating dairy more often — while most Czech Roma can't digest milk and eat less dairy. The study shows these two things match up perfectly.
