Fat Foods
to Soothe Pain and Anger

Fatty meal seems to have comforting and pain-reducing effect.
Research conducted by the Center for Human
Nutrition, University of
Sheffield,
UK, has shown that fatty meal seems to have comforting and
pain-reducing
effect.
A meal of full-fat pancakes before the pain
sensitivity test (a hand
immersed
in ice-cold water) decreased the sense of pain comparing with low-fat,
high-carbohydrate
pancakes of equal calorific value.
However, when these people had the same
amount of fat,
carbohydrates,
and calories infused as a liquid meal directly in the stomach through a
tube,
the pain sensation was not change by any meal.
"From this evidence we think that there must
have been a heavy
sensory
component involved in the study," researchers suggested.
In another study, also from the University
of Sheffield, researchers
showed
that cutting down on dietary fat (from 41% to 25%) caused a higher
'anger-hostility'
ratings. Those who continued with a high-fat diet not only kept the
'anger-hostility'
ratings unchanged but also felt that their tension and anxiety went
down.
The main character in this play may well be
cholecystokinin - "CCK."
CCK
is a gut hormone that is being released in response to fatty food more
readily than to any other food. Since CCK inhibits gastric motility,
fatty foods slow
stomach emptying resulting in a greater 'satiety' or fullness.
Interestingly, CCK is under influence of the
"body fat" hormone
Leptin
(mutations in Leptin gene results in obesity.)
CCK is known for its strong general
regulatory properties. These
functions
were shown to be under CCK control:
