People with a certain gene version (APOE4) tend to have higher bad cholesterol before they even start eating special broccoli, compared to those with another gene version (APOE2).
Scientific Claim
The APOE4 allele is associated with higher baseline LDL cholesterol levels compared to the APOE2 allele in middle-aged adults at moderate cardiovascular risk.
Original Statement
“At baseline, individuals with the E4/E4 genotype had significantly greater levels of TC and LDL-C than those individuals with E2/E3 genotype (Table 2)... E4/E4 genotypes have significantly greater Total-C and LDL-C than E2/E3 genotypes [p = 0.001, ANOVA].”

Diet rich in high glucoraphanin broccoli reduces plasma LDL cholesterol: Evidence from randomised controlled trials
This study only looked at whether eating a special kind of broccoli lowers cholesterol, not whether people with a certain gene (APOE4) naturally have higher cholesterol than others with a different gene (APOE2).
