- Consumer Knowledge about Dietary Relevance of Fruits and Vegetables: A Study Involving Participants from Portugal and FrancePublication . Le Turc, Nolwenn; Silva, Ana Jaquelina; Florença, Sofia De Guiné E; Raposo, António; C. Goncalves, J.; Lima, Maria João; Teixeira de Lemos, Edite; Guiné, RaquelFruits and vegetables are recommended as low-calorie foods that contribute to the proper intake of necessary micronutrients, macronutrients, and bioactive compounds with health benefits. However, the recommendations for the dietary intake of these foods fail to be attained in most European countries. For this reason, promoting more knowledge about the health effects of fruits and vegetables is essential to decrease the incidence of chronic diseases. This study was conducted to investigate the knowledge of the health benefits of fruits and vegetables among the population of Portugal and France. The present work involved a questionnaire survey of 639 participants (257 from Portugal and 382 from France). The results revealed that most participants were young females (68.9%) with good education (76%) and an average weight range. They consumed a varied diet (57%) but had body dissatisfaction (63.2%). The respondents had good knowledge about the health effects of fruits and vegetables. However, the French population knew more about the theme than the Portuguese. Portuguese individuals were more likely to have incomplete information. Gender and education significantly influenced knowledge levels, with females and highly educated individuals demonstrating greater understanding. Dissatisfaction with body weight drives individuals to seek nutrition information. This investigation enhances our comprehension of the factors that affect knowledge of vegetable and fruit consumption among young adults in Portugal and France. Moreover, it highlights the importance of implementing focused educational programs to enhance nutrition literacy, particularly for less-aware demographic groups. Going forward, a more in-depth analysis of these factors could assist in creating more efficient strategies to encourage healthier dietary habits and improve nutrition literacy among these communities.

- Effect of Cynara cardunculus L. var. altilis (DC) in inflammatory bowel diseasePublication . Mateus, Vanessa; Estarreja, João; Silva, Inês Filipa Janeiro; Barracosa, Paulo; Teixeira de Lemos, Edite; Pinto, RuiCynara cardunculus L. var. altilis (DC) is a plant generally associated as an ingredient in the Mediterranean diet. The polyphenols present in this plant provide pharmacological and nutritional properties. C. cardunculus L. has been used throughout animal studies, which demonstrated an anti-inflammatory effect. Inflammatory bowel disease (IBD) is a chronic inflammatory disorder of the gastrointestinal tract. Since there is not a known cure, the research of new possible pharmacological approaches is essential. This study aims to evaluate the effect of an aqueous extract of C. cardunculus L. dry leaves in a 2,4,6-Trinitrobenzenesulfonic acid (TNBS)-induced colitis model. Methods: CD-1 mice with TNBS-induced colitis received an intraperitoneal (IP) administration of C. cardunculus L. once per day for 4 days. Results: The C. cardunculus L. demonstrated a beneficial effect in this experimental model of IBD with anti-inflammatory action through the reduction of tumor necrosis factor (TNF)-α levels. It also demonstrated a beneficial influence on the extra-intestinal manifestations related to IBD, with the absence of significant side effects of its use. Conclusions: The extract of C. cardunculus L. dry leaves can become an interesting tool for new possible pharmacological approaches in the management of IBD.
- Exercise training is associated with improved levels of C-reactive protein and adiponectin in ZDF (type 2) diabetic rats.Publication . Teixeira de Lemos, Edite; Reis, Flávio; Baptista, Sofi a; Pinto, Rui; Sepodes, Bruno; Vala, Helena; Rocha-Pereira, P.; Silva, Alice Santos; Teixeira, FredericoChronic low-grade systemic infl ammation is a feature of such chronic diseases as cardiovascular disease and type 2 diabetes (T2D). There is evidence that regular exercise is effective as a treatment in these situations. This study intended to assess the levels of two infl ammatory mediators, C-reactive protein (CRP) and adiponectin, in Zucker Diabetic Fatty (ZDF, fa/fa) rats, an experimental model of T2D, and to determine whether exercise-induced changes in insulin resistance could be explained by modifi cations in these infl ammation markers. Material/Methods: Male ZDF (Gmi fa/fa) rats and their littermates (Gmi +/+), aged 8 weeks, were randomly assigned in two groups: an exercise trained and a sedentary one. Swimming was conducted 1 h/day 3 days/week for 12 weeks. The rats were sacrifi ced 48 h after the last round of exercise. Rats had their body weight, insulin, adiponectin, CRP, as well as glucose, total cholesterol, triglycerides, MDA, and SOD measured and HOMA-IR calculated before and after the 12-week swimming training. Results: In the ZDF (fa/fa) rats underwent swimming exercise, all the metabolic abnormalities were totally or partially prevented ( p<0.001), namely the hyperglycemic, hyperinsulinemic, and dyslipidemic pattern observed in their sedentary counterparts. Furthermore, even without body weight change, a plasma adiponectin increase (28.0%) and a CRP decrease (12.7%) were also observed. Conclusions: A 12-week thrice-weekly swimming training was associated with improved measures of chronic in- fl ammation markers as measured by adiponectin and CRP. Moreover, improvements in insulin sensitivity resulting from swimming exercise appeared to be related to changes in these infl ammatory mediators.

- Regular Physical Exercise as a Strategy to Improve Antioxidant and Anti-Inflammatory Status: Benefits in Type 2 Diabetes MellitusPublication . Teixeira de Lemos, Edite; Oliveira, Jorge; Páscoa Pinheiro, João; Reis, FlávioOver the last 30 years the combination of both a sedentary lifestyle and excessive food availability has led to a significant increase in the prevalence of obesity and aggravation of rates of metabolic syndrome and type 2 diabetes mellitus (T2DM). Several lines of scientific evidence have been demonstrating that a low level of physical activity and decreased daily energy expenditure leads to the accumulation of visceral fat and, consequently, the activation of the oxidative stress/inflammation cascade, which underlies the development of insulin resistant T2DM and evolution of micro, and macrovascular complications. This paper focuses on the pathophysiological pathways associated with the involvement of oxidative stress and inflammation in the development of T2DM and the impact of regular physical exercise (training) as a natural antioxidant and anti-inflammatory strategy to prevent evolution of T2DM and its serious complications.
