The C677T polymorphism of the MTHFR gene is associated to several biochemicals imbalances, as changes in folic acid serum levels and some inflammatory markers, elevating the oxidative stress and increasing the risk of developing non communicable diseases (NCDs). Thus, a diet containing folate as a main antioxidant nutrient, could reduce not only the oxidative stress, but also has many others benefits for individuals with this genetic alteration, like the anti-inflammatory function, which could help restore the altered serum levels and minimizing or avoiding the development of future diseases. The aim of this study was to evaluate the influence of the C677T polymorphism of the MTHFR gene and the effect of a diet containing folate in the inflammatory markers levels, such as homocysteine, Tumor Necrosis Factor alpha (TNF-α) and interleukins in women with overweight or obesity. This is an intervention study, double-blind, held in a city in northeastern Brazil, with a sample of 48 adult women (20-59 years old) with BMI among 26.19 kg / m² and 49.64 kg / m². In which we evaluated the TNF-α levels, Interleukins 1β, Interleukin 6, Interleukin 8, Interleukin 12p70, Interleukin 10, homocysteine, folic acid and in addition to these markers evaluation, were made the genotyping for the C677T polymorphism in the MTHFR gene and the food consumption assessment by the 24 hour dietary recall (24HR). For the intervention, the sample was divided by randomization into two groups, each one with 24 indivuals, receiving daily during 8 weeks, a salad with 300g vegetables containing 191 ug of folate for group 1 and 90 ug for group 2.

Non-alcoholic fatty liver disease (NAFLD) is a condition of excessive hepatic lipid accumulation in subjects that consume less than 20g ethanol per day, without other known causes as drugs consumption or toxins exposure. In Western countries, the rate of this disease lies about 30% in the general adult population. The process of developing NAFLD can start from simple steatosis to non-alcoholic steatohepatitis (NASH), which eventually can lead to cirrhosis and hepatocellular carcinoma in the absence of alcohol abuse. Liver biopsy is considered the "gold standard" of steatosis, fibrosis and cirrhosis. However, it is rarely performed because it is an invasive procedure and investigators are focusing in the application of non-invasive liver damage scores for diagnosis. The pathogenesis of NAFLD is multifactorial and triggered by environmental factors such as unbalanced diets and overnutrition as well as by lack of physical activity in the context of a genetic predisposition. Nowadays, the treatment of NAFLD is based on diet and lifestyle modifications. Weight loss, exercise and healthy eating habits are the main tools to fight NAFLD. Nevertheless, there is no a well characterized dietary pattern and further studies are necessary. With this background, the general aim of this project is to increase the knowledge on the influence of nutritional/lifestyle interventions in obese patients with NAFLD, as well as contribute to identify non-invasive biomarkers/scores to early diagnosis of this pathology in future obese people.
