The incorporation of red meat in higher-HEI diets supports brain-health critical nutritional adequacy, and gut microbial diversity
Abstract
We
evaluated
whether
red
meat
could
be
integrated
into
a
high
Healthy
Eating
Index
(HEI)
diet
to
improve
brain
health-critical
nutrient
adequacy
without
compromising
quality,
mental
health,
or
gut
microbiota.
Using
data
from
3,643
adults
in
the
American
Gut
Project,
participants
were
stratified
four
groups:
high-HEI
(≥
80)
with
(HH-R),
(HH-NR),
low-HEI
(<
(LH-R),
and
(LH-NR).
Both
groups
maintained
healthy
BMI
values
regardless
of
intake.
HH-R
had
higher
protein
intake
lower
carbohydrate
intake,
saturated
fat
levels
within
recommended
limits.
Brain

Therefore,
these
