Introduction:This study aimed to determine the relationship between symptoms of anxiety and/or anhedonia (inability to feel pleasure) and diet quality during confinement due to COVID-19 in rural populations in Latin America. Methods: This was a multicentric, cross-sectional study. An online survey was applied, which included the Beck Anxiety Inventory, Snaith-Hamilton Pleasure Scale for assessing the presence of anhedonia, the Food Intake Questionnaire and sociodemographic questions. Results:The study included 10 552 people from 11 countries; 708 participants were living in rural areas. More than half of the participants were quarantined at the time of the survey. Diet quality was inversely associated with anhedonia (p<0.001) and anxiety (p=0.003). In addition, a healthier diet was associated with being female (p=0.030), having a higher level of education (p=0.008) and country of residence (p=0.001). Conclusion:Among the rural population during the COVID pandemic, this study found a worse diet quality was associated with symptoms of anhedonia and anxiety, as well as lower level of education and being male. Proposals to improve the quality of the diet could include interventions aimed at people's mental health.

Background and objectives The confinement by COVID-19 has affected the food chain and environments, which added to factors such as anxiety, frustration, fear and stress have modified the quality of the diet in the population around the world. The purpose of this study was to explore diet quality during the COVID-19 pandemic in 11 Latin American countries. Methodology Multicentric, cross-sectional study. An online survey was applied to residents of 11 Latin-American countries, during April and May 2020, when confinement was mandatory. Diet quality was evaluated using a validated questionnaire. Result 10,573 people participated in the study. The quality of the food by country shows that Colombia presented the best quality, while Chile and Paraguay presented the lowest. When comparing the overall results of diet quality by gender, schooling and age, women, people with more schooling and people under 30 years of age, presented better diet quality. The regression model showed that the variables associated with diet quality were: age (df = 3, F = 4. 57, p < 0.001), sex (df = 1, F = 131.01, p < 0.001), level of education (df = 1, F = 38.29, p < 0.001), perception of weight change (df = 2, F = 135.31, p < 0.001), basis services (df = 1, F = 8.63, p = 0.003), and quarantine (df = 1, F = 12.14, p = 0.001). Conclusion It is necessary for governments to intervene to reverse these indicators, considering that inadequate feeding favors the appearance of no communicable diseases, which favor a higher risk of infection and worse prognosis with COVID-19.

The species Passiflora tripartita Kunth (tumbo) is endemic to South America, whose edible fruits are a rich source of antioxidant metabolites. This study aimed to develop a probiotic yogurt with tumbo fruit pulp, consisting of an adequate antioxidant capacity related to its content in phenolic compounds, flavonoids, and carotenoids, and with good acceptability. Antioxidant capacity was determined by radical scavenging capacity test (DPPH●) and cation radical scavenging capacity test (ABTS+●), total phenol content by Folin Ciocalteu method, total flavonoids, and carotenoids by spectrophotometric method, on days 1, 7, 14 and 21 of storage. The surface plate count method quantified Lactic Acid Bacteria (LAB). The results evidenced that at day 21 of the analysis, the antioxidant capacity presented high values (DPPH●: 8.774 mg GAE/g, 3.386 mg TAE/g, 6.159 mg AAE/g; ABTS+●: 11.630 mg GAE/g, 7.018 mg TAE/g, 9.218 mg AAE/g), the content of phenolic compounds presented high values (3746.389 mg TPGAE/g; 2355.933 mg TPTAE/g), as well as total flavonoids (52.421 mg Quercetin/g) and carotenoids (72.109 µg β-carotene/g). Yogurt presents a value of 3.4 x 108 CFU/g of LAB and it is therefore considered a probiotic. High values were determined as the sensory characteristics such as odor (6.89), color (6.97), texture (6.94), flavor (6.97), and acceptability (6.94), thus being analyzed according to the hedonic scale in 200 panelists. The physicochemical and microbiological quality of the yogurt complies with current regulations. In conclusion, the probiotic yogurt developed with tumbo fruit pulp had a high amount of LAB. It presented high antioxidant capacity correlated with its high content of phenolic compounds, flavonoids and carotenoids, which remained high during the 21 days of storage. Furthermore, it showed high acceptability and had adequate physicochemical and microbiological quality.

Objective We estimated the association between the consumption of select ultra‐processed food (UPF), homemade fried food and overweight/obesity in Latin American university undergraduate students during the COVID‐19 pandemic. Methods We conducted an analytical cross‐sectional study. 4539 university students (73.6% female, mean age 22.5 ± 4.4) from 10 Latin American countries completed a self‐administered online survey. UPF eating habits and homemade fried food were measured according to a validated survey. Height and body weight were self‐reported. Body mass index (BMI) was calculated. A BMI ≥25 kg/m2 was categorized as overweight/obesity. Ordinal logistic regression models were applied. Results Snacks (36.2%) and homemade fried food (30.2%) had a higher prevalence of consumption than sugary drinks (22.5%) and fast food (7.2%). The greatest strength of association was found between fast food consumption [odds ratio (OR) = 2.16; 95% confidence interval (CI): 1.63–2.85], sugary drinks [OR = 2.05; CI: 1.63–2.59] and homemade fried food [OR = 1.46; CI: 1.16–1.85] with overweight/obesity. Conclusion Latin American university undergraduates present risky eating behaviors associated with overweight and obesity. Effective policies to promote healthy eating should be incorporated and issued from universities to reduce the consumption of UPF and promote homemade, healthier and more natural food.
