Chronic non-communicable diseases (NCDs) are the principal cause of death in the world. In Mexico, type 2 diabetes (T2D) is the leading cause of death. An increase of 5kg/m2 in the body mass index (BMI) significantly increased the mortality by T2D. Metabolic surgery is an alternative treatment for people who are living with obesity and T2D. Metabolic surgical procedures induce anatomo-physiological changes, which improves glycemic control, decreases the risk of mortality due to T2D, promotes weight loss, and body fat, and in some cases, have the potential for the remission of T2D. These surgeries impact nutritional status in the short, medium and long term, therefore, a nutritionist should evaluate and implement nutrition interventions in these individuals. There are no guidelines for nutrition to promote and maintain remission of T2D in individuals with these types of surgeries. The objective of this review is to summarize current scientific evidence to guide the clinical practice in this context. The therapeutic goals include, besides promoting weight loss, monitor waist circumference and body composition, evaluation of glycemic control with regulation of hypoglycemic drugs, and avoiding nutritional deficiencies. For adequate results it is recommended to incorporate behavioral strategies and nutritional education focused on healthy and sustainable eating patterns. Adequate nutritional monitoring favors a better prognosis in the fulfillment of therapeutic objectives of both diseases after metabolic surgery.

Introduction: breastfeeding (BF) and complementary feeding (CF) are fundamental practices in the human life process, since it contributes to the growth, maturation and development of the infant; as well as providing short, medium and long term benefits. Objective: to determine the proportion of breastfeeding in its different forms and to characterize the complementary feeding scheme in children born from 2015 to 2017 who currently attend the primary care in a city in the south of the Mexican Republic. Material and methods: cross-sectional analytical study, the sample consisted of 150 mothers, who were surveyed for consecutive cases; as long as they met the inclusion criteria. Results: the practice of BF was high 91.3%, while the exclusive breastfeeding (EBF) was 42% with an average duration of 1.81 months, 64.1% of the population studied used milk formula (MF). Women with basic education gave a higher proportion of complementary breastfeeding. The average onset of complementary feeding was 5.9 months, in the scheme of start of CF there is a significant absence of meat; since this food group was introduced on average in the tenth month. Sugar and salt addiction were carried out early 7.57 and 9.69 months respectively. Conclusion: there is a low duration of the EBF and a high use of MF, the CF scheme reflects an important iron deficiency, which can impact on the health of the infant; as well as the early introduction of sugar and salt.
