Whereas this effect has been mostly explained in terms of weakening cognitive control, cognitive effort may also bias behavioral choices by amplifying the hedonic and emotional impact of rewards. We report parallel findings with animals and humans supporting this hypothesis.

Exposure to highly palatable food is believed to induce behavioral and neurobiological changes that may produce addiction-like behavior and increase the risks of obesity and overweight.

In addition, it is not clear whether effects of exposure to highly palatable diets (HPD) persist after their discontinuation, which would indicate long-term risks to develop addiction-like behavior.

Article Synopsis
  • A pilot study investigated the gut and oral microbiota in multiple sclerosis (MS) patients and found significant bacterial alterations compared to healthy volunteers (HV).
  • The analysis revealed decreased diversity and specific bacteria depletion in MS patients, along with enrichment of inflammation-associated bacteria and altered microbial pathways.
  • A distinctive oral metabolite signature was identified in MS patients, which has high specificity for discriminating them from HV and patients with rheumatoid arthritis, suggesting the potential for future research on oral microbiota in autoimmune diseases.
