What experts say?

  • We don't often think about how what we eat impacts the activity in ourbrain.
  •  We know people report feeling fuller after eating walnuts.
  • But it was pretty surprising to see evidence of activity changing in thebrain related to food cues.
  •  And by extension what people were eating and how hungry they feel.
  •  To determine exactly how walnuts quell craving for food, experts used functional magnetic resonance imaging (fMRI).
  •  In addition, to observe how consuming walnuts changes activity in the brain.
  •  The scientists recruited a small group of volunteers with obesity to live inBIDMC's Clinical Research Centre (CRC) for two five-day sessions.

Sessions:

  •  During one session, volunteers consumed daily smoothies containing 48grams of walnuts.
  • During their other stay.
  • They received a walnut-free but nutritionally comparable placebo smoothie.
  • In addition, flavoured to taste exactly the same as the walnut-containingsmoothie.

Previous Studies:

  • As in previous observational studies, participants reported feeling lesshungry during the week.
  •  They consumed walnut-containing smoothies than during the week theywere given the placebo smoothies.
  •  Functional MRI tests administered on the fifth day of the experimentgave the team a clear picture as to why.
  • While in the machine, study participants were shown images of desirable foods like hamburgers and desserts.
  • Neutral objects like flowers and rocks and less desirable foods like vegetables.

According to expert:

  • This is a powerful measure.
  •  When participants eat walnuts, this part of their brain lights up.
  •  And we know that's connected with what they are telling us about feeling less hungry or more full.This area of the insula is likely involved in cognitive control andsalience.Meaning that participants were paying more attention to foodchoices.And selecting the less desirable or healthier options over the highly desirable or less healthy options.
