The Mediterranean diet (MD) is recognized as one of the healthiest dietary patterns and has
benefits such as improving glycaemic control among patients with type 2 diabetes (T2DM). Our aim is
to assess the effectiveness of a multifactorial intervention to improve adherence to theMD, diet quality
and biomedical parameters. The EMID study is a randomized and controlled clinical trial with two
parallel groups and a 12-month follow-up period. The study included 204 subjects between 25–70 years
with T2DM. The participants were randomized into intervention group (IG) and control group (CG).
Both groups received brief advice about healthy eating and physical activity. The IG participants
additionally took part in a food workshop, five walks and received a smartphone application for three
months. The population studied had a mean age of 60.6 years. At the 3-month follow-up visit, there
were improvements in adherence to the MD and diet quality of 2.2 and 2.5 points, compared to the
baseline visit, respectively, in favour of the IG. This tendency of the improvement was maintained,
in favour of the IG, at the 12-month follow-up visit. In conclusion, the multifactorial intervention
performed could improve adherence to the MD and diet quality among patients with T2DM.
