Unhealthy diets increase the likelihood of being overweight or obese among African migrant students in China, but not among African non-migrant students: a cross-sectional study

BackgroundThe impact of non-communicable diseases (NCDs) is disproportionately felt by immigrants from low- to medium-income countries (LMICs), partly due to their dietary habits. To thrive in their new environment, migrants either omit or consume certain food items, which could lead to nutritional deficits. As a result, most migrants experience more NCDs than their compatriots in their native countries. Therefore, we evaluated the difference in dietary habits, quality, and the influencing factors of overweight or obesity among African migrant students in Nanjing (China) and non-migrant students in Africa using cross-sectional data.MethodsThe researchers used the food frequency questionnaire and the global diet quality score metrics to assess food intake and quality, respectively. Then, cross-tabulation was employed to explore the differences between the groups in meal skipping, eating habits, and diet quality. Finally, the factors associated with overweight or obesity were assessed with binary logistic regression stratified by African students in Nanjing and students in their native countries.ResultsApproximately 678 responses were received, mainly between 18–25 years (46.7%) and 26–36 years (45.4 %). The majority of them (52.3%) were international students. The non-migrant African students' diets lacked citrus fruits (22.2%), deep orange fruits (15.4%), deep orange vegetables (18%), cruciferous vegetables (24.6%), and dark leafy vegetables (26.5%). While the African migrant students consumed more high-fat dairy (50.7%), processed meats (23.9%), sweets and ice creams (51.3%), sugar-sweetened beverages (40.5%), and juice (61.5%), p < 0.001. Furthermore, consuming late-night meals constantly [Exp (B) = 39.607, p = 0.049], eating twice a day [Exp (B) = 6.527, p = 0.036], consuming red meat [Exp (B) = 29.287, p = 0.001], processed meats [Exp (B) = 719.979, p = 0.0011], refined grains and baked foods [Exp (B) = 15.752, p = 0.013], and sweets and ice cream [Exp (B) = 193.633, p = 0.006] were factors inducing overweight or obesity among only African migrant students.ConclusionControlling the what (Western diet and nature of late-night meals) and the when of eating can drastically reduce their influence on obesogenic condition formation in African migrant students in China and elsewhere

Development of a bilayer biodegradable packaging material enriched with coffee waste extract for cake preservation

Abstract The study aimed to develop an active packaging, functionalized by spent coffee grounds extracts (SCGE) to preserve cake. The antioxidant extracts were obtained using three extraction methods: conventional extraction (CE), ultrasound‐assisted extraction (UAE), and microwave‐assisted extraction (MAE). The SCGE obtained with UAE and MAE produced the highest total phenolic contents and antioxidant activities, and were incorporated into bilayer films composed of polylactic acid, konjac glucomannan, and wheat gluten. The SCGE improved the film's antioxidant activity (8.40 to 90. 56%) and oxygen transmission rate (5.05 ± 0.04 to 2.22 ± 0.13). Active packaging with microwave extracts was more effective in preserving cake's lipids than the ultrasound extracts as measured by the peroxide value, thiobarbituric acid, and acid value during 21 days of storage. Overall, the study demonstrates the potential safe utilization of coffee waste in active packaging

Table_1_Healthy eating habits and a prudent dietary pattern improve Nanjing international students’ health-related quality of life.DOCX

PurposeLow-quality dietary practices, such as fast food consumption and skipping meals, deteriorate the quality of life. However, the available studies on diet and health-related quality of life (HRQoL) used matrices not specific to nutrition. Moreover, how diet affects the HRQoL of international students in China is unknown. Therefore, using a cross-sectional study, the effect of dietary patterns and habits on the HRQoL of international students in Nanjing, China, was examined.MethodsThe researchers collected dietary data using a food frequency questionnaire (FFQ) from February to March 2022. Then, the Food Benefit Assessment (FBA) was used to access HRQoL. Finally, the effect of eating habits and dietary patterns on HRQoL was explored using multilinear regression.ResultsApproximately 454 responses were obtained, with the responses mostly from male subjects (56.4%) and those aged 26 years and above (75.6%). The quality of life according to the food consumed was about average for all the constructs except for aesthetics and disease prevention, as 65.8% skipped meals, particularly breakfast (47.8%). Furthermore, three dietary patterns were identified: prudent, Western, and animal protein patterns. Consequently, by skipping breakfast, vitality (β = −2.362, p = 0.04), wellbeing (β = −3.592, p = 0.007), digestive comfort (β = −4.734, p = 0.008), and disease prevention (β = −5.071, p = 0.031) were all reduced. However, consuming at least three meals daily enhanced vitality (β = 2.254, p = 0.003) and disease prevention (β = 4.441, p = 0.019). Furthermore, aesthetics (β = 4.456, p = 0.05), physical appearance (β = 5.927, p = 0.003), and vitality (β = 3.323, p = 0.009) were also significantly increased by healthy dietary patterns. However, a more Westernized diet led to frequent snacking (β = −4.631, p = 0.032), a decline in wellbeing (β = −5.370, p ConclusionThis research indicates that healthy eating habits and patterns positively impact international students’ HRQoL. Therefore, the appropriate authorities should advise students to consume healthy foods regularly to improve their HRQoL.</p
