Which specific liver condition showed prevention in rat studies using soluble *H. tuberosus* fiber?

Non-Alcoholic Fatty Liver Disease (NAFLD)

Scientific preclinical investigations specifically targeted the effects of Jerusalem artichoke fiber on Non-Alcoholic Fatty Liver Disease, a condition often arising secondary to metabolic syndrome and high-fructose consumption. Studies involving rats subjected to diets rich in fructose demonstrated that the soluble dietary fiber component derived from *Helianthus tuberosus* was effective in mitigating the negative metabolic shifts associated with this dietary challenge. This mitigation included preventing the excessive accumulation of fat within the liver tissue, highlighting a preventative role against the onset of NAFLD in those experimental models. This effect was attributed primarily to the soluble fiber fraction of the vegetable.
