The Claim
In young Caucasian adults, the rs2228603-T allele in the NCAN gene is associated with a greater reduction in liver fat, as measured by CAP score, following a 3-week high-fructose beverage intervention, with T-allele carriers exhibiting a mean CAP score decrease of 23.3 ± 5.8 dB m⁻¹ compared to 18.2 ± 43.2 dB m⁻¹ in CC carriers, although this association is no longer statistically significant after adjustment for age, sex, and body composition.
What the research says
Challenges is higher
Challenge is ahead, but a single strong supporting 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.
In young Caucasian adults, individuals with the rs2228603-T allele in the NCAN gene experience a larger decrease in liver fat after consuming high-fructose beverages for three weeks, compared to those with the CC genotype, but this difference is not significant when accounting for age, sex, and body composition.

When fructose is consumed, the liver converts it into fat more efficiently than glucose, and at the same time, the liver's ability to package and send fat out to the body is reduced, causing fat to build up inside liver cells.
What the research says
1 studyPeople with a certain gene version did seem to lose a bit more liver fat after drinking sugary drinks for three weeks, but when scientists accounted for age, sex, and body fat, that difference vanished — meaning the gene probably doesn’t actually make a real difference.
