Diet, Mediterranean

The goal of this clinical trial is to compare the effects of two different healthy lifestyles on outcomes for those with bipolar disorder. The goals are to understand the acceptability of time-restricted eating and the mediterranean diet for those who are already receiving medication treatment for bipolar disorder, and to consider how these two food plans predict changes in manic symptoms, depressive symptoms, and Quality of Life. Participants will complete daily measures of eating, sleep and mood for two weeks, and then will be assigned to follow one of the two food plans for eight weeks. The investigators will measure symptoms and Quality of Life at baseline and during and after the food plan.

The main objective is to evaluate the effect of the Mediterranean diet during pregnancy and the first two years of the child\'s life on the child\'s neurodevelopment and behavior (externalizing and internalizing disorders) measured at one and a half and two years. Secondary objectives are to evaluate the effect of the Mediterranean diet on: body composition at two years of age in infants (densitometry) and of the mother at 3 months postpartum, the incidence of allergic disease in infants, the fetal and infant ́s growth and metabolic risk in the mother during pregnancy and in the boy/girl at two years (fasting glucose: insulin, HOMA), LDL and HDL cholesterol, and micronutrient status (iron, calcium, phosphorus, magnesium, sodium, potassium, chloride, selenium, zinc and LCPUFAs). Randomized controlled clinical trial with a 1:1 ratio, parallel and open label. Group 1: Mother-child binomial with nutritional intervention; Group 2: Mother-child binomial as a control group (with follow-up without intervention). Assuming a loss of 25% (10% at follow-up, 15% failure of nutritional intervention) we would need a sample size of 267 patients per group. 1. Evaluation of neurodevelopment using the Bayleys scale version -III, at 2 years of age. 2. Behavioral assessment CBCL at 1.5 and two years and BRIEF-P at two years.
