PLENARY SESSION 1: FOOD 8 th Int. Conference on LCA in the
Agri-Food Sector, 1-4 Oct 2012
Figure 2. Partial (age, sex and energy-adjusted) Pearson correlations between diet-related greenhouse gas
emissions (GHGE, in g CO2e/d) and the consumption (in g/d) of each food group by adults (n=1918) participating
in the INCA2 survey. All coefficients are significantly different from 0 (p< 0.001).
3.3. Food consumption in the four classes of nutritional quality
For both sexes, individuals with high quality diets had higher food intakes and their diets contained significantly
more fruit and vegetables and less sweets and salted snacks than low quality diets (data not
shown). For both sexes, high quality diets contained significantly more fish and less delicatessen (data not
shown) than low quality diets, but the quantity of meat did not differ between nutritional quality classes
(class 1 diets contained 69 and 51 g/d of meat, in men and women respectively, data not shown). For women,
high quality diets also contained more poultry and eggs than low quality diets, so that the total intake of the
MFPE group increased with increasing nutritional quality for them.

The crude and adjusted values of daily diet-related GHGE in the four classes of nutritional quality are
shown Figure 4. Without adjustment (panel A), GHGE was not significantly different between the four
classes for men (p=0.27) and it was greater in the highest nutritional quality class for women (p=0.0021).
After adjustment for energy intakes (panel B), diets with a high nutritional quality tend to be associated with
higher GHGE values than diets with a lower nutritional quality (p
