Background:
Ultra-processed foods (UPF) have been associated with major
diet-related public health issues that share underlying drivers
with climate change. Both challenges require major changes to
the food system and so the potential benefits to health and the
environment present a double motivation for transformation.
Our aim is to assess the impacts of UPF on total greenhouse
gas emissions (GHGE), water and ecological footprints in
Brazil food purchases.
Methods:
We have used data from 4 Brazilian Household Budget Surveys
(1987, 1996, 2003, 2009). Each food item was classified into
NOVA food groups (unprocessed/minimally processed, culin-
ary ingredients, processed and ultra-processed). The informa-
tion was linked to nutrition and footprint data. Purchases were
converted into grams per capita per day to estimate total
energy (kcal), percentage of energy from UPF, as well as total
GHGE, water and ecological footprints. We performed linear
regression to calculate year-adjusted means of footprints per
1000 Kcal by year-specific quintiles of UPF participation in the
total energy. The data were analysed in R v.3.6.1 and STATA
SE 14.1.
Results:
The mean UPF participation in total energy varied from 13%
(SD 2.4) in the 1st UPF quintile to 29% (SD 5.1) in the 5th
quintile. The footprints increased linearly across quintiles: the
mean g CO2eq varied from 1312 in the 1st to 1721 in the 5th
UPF quintile (p-trend<0.001); the mean litres of water varied
from 1420 in the 1st to 1830 in the 5th quintile (p-
trend<0.001); the mean m2 varied from 9.4 in the 1st to
12.3 in the 5th quintile (p < 0.001).
Conclusions:
The environmental impacts were higher for Brazilian diets with
a larger fraction of energy from UPF. Specifically, low UPF
diets seem to have lower GHGE, water and ecological
footprints. Our findings offer new motivators for dietary
change to simultaneously healthier and more sustainable
eating patterns and will be of relevance to consumers and
policymakers.
Key messages:
Diets high in UPF cause more climate impact than diets with
lower levels of UPF.
Healthy and sustainable dietary patterns should be low in
ultra-processed foods.

Background:
Mediterranean diet has been shown to promote beneficial
effects on health, while ultra-processed food (UPF) consump-
tion has been associated with lower diet quality and higher risk
for non-communicable diseases. Our aims were to explore the
adherence to a Mediterranean dietary pattern (MDP) in
Portugal and its association with sociodemographic factors
and UPF consumption.
Methods:
Participants were from the Portuguese National Food,
Nutrition and Physical Activity Survey 2015-2016, aged 18-
84y (n = 3,852). CAPI face-to-face interviews were used
including 2 dietary 24-h recalls. UPF were identified using
NOVA classification. Adherence to MDP was defined by the
Mediterranean Diet Score (MDS), which may vary from 0 to 9.
MDS6 was considered as high adherence. Weighted multi-
variate logistic regression analysis was used to explore
associations of high adherence to MDP with sex, age, region,
educational level, family income and dietary share of UPF
groups.
Results:
High adherence to MDP was observed for 19.6% of
participants and was inversely associated with higher con-
sumption of UPF, namely, sugar-sweetened beverages
(OR = 0.924; 95%CI 0.883-0.966), confectionery (OR = 0.893;
95%CI 0.816-0.977), sweet snacks (OR = 0.953; 95%CI 0.923-
0.985), cakes/desserts (OR = 0.956; 95%CI 0.934-0.978) and
meat products (OR = 0.922; 95%CI 0.874-0.972). Being female
(OR = 0.629; 95%CI 0.471-0.841) and not from the North or
Alentejo regions were inversely associated with high adherence
to MDP. There was no relation between income and adherence
to MDP. The higher the level of education or age, the higher
the odds of high adherence to MDP (OR = 2.573; 95%CI
1.741-3.803 and OR = 1.028; 95%CI 1.020-1.037, respectively).
Conclusions:
Actions to improve adherence to MDP in Portugal should
consider discouraging UPF consumption and be addressed to
specific subgroups.

Key messages:
High adherence to a Mediterranean dietary pattern was
observed for near 20% of Potuguese over 18 years old. The
higher the level of education or age, the higher the odds of
high adherence to MDP.
