Mediterranean Diet Social Network Impact along 11 Years in the Major US Media Outlets: Thematic and Quantitative Analysis Using Twitter

Background: Media outlets influence social attitudes toward health. Thus, it is important that they share contents which promote healthy habits. The Mediterranean diet (MedDiet) is associated with lower cardiovascular disease risk. Analysis of tweets has become a tool for understanding perceptions on health issues. Methods: We investigated tweets posted between January 2009 and December 2019 by 25 major US media outlets about MedDiet and its components as well as the retweets and likes generated. In addition, we measured the sentiment analysis of these tweets and their dissemination. Results: In total, 1608 tweets, 123,363 likes and 48,946 retweets about MedDiet or its components were analyzed. Dairy (inversely weighted in MedDiet scores) accounted for 45.0% of the tweets (723/1608), followed by nuts 19.7% (317/1608). MedDiet, as an overall dietary pattern, generated only 9.8% (157/1608) of the total tweets, while olive oil generated the least number of tweets. Twitter users’ response was quantitatively related to the number of tweets posted by these US media outlets, except for tweets on olive oil and MedDiet. None of the MedDiet components analyzed was more likely to be liked or retweeted than the MedDiet itself. Conclusions: The US media outlets analyzed showed reduced interest in MedDiet as a whole, while Twitter users showed greater interest in the overall dietary pattern than in its particular components.

Identifying dietary pattern associated with adiposity among Malaysian young adults

BACKGROUND: Recognizing food groups consumption in young adults offers an opportunity to improve dietary pattern in early adulthood. OBJECTIVE: Hence, this cross-sectional study aimed to determine food groups’ intake of young adults and to identify food groups associated with adiposity. METHODS: Youths aged 18–25 years old from private universities in Klang Valley, Malaysia, participated in the study (n = 294). Three days 24-hour dietary recall assessed youths’ food groups intake. Adiposity (BMI, body fat percentage, visceral fat level, waist circumference) was determined based on standard protocol. Height was measured using SECA 206 body meter, while weight, body fat percentage, and visceral fat level were measured using the Omron HBF-356 Body Fat Analyzer. Waist circumference was determined using a measuring tape. RESULTS: In total, 49.3% and 34.7% of youths were overweight/obese and abdominally obese, respectively. The median visceral fat level was 4 (6). Youths consumed 214 (247) kcal of ultra-processed foods daily and exceeded the sugar [32.43 (41.20) g] and sodium recommendation [2425.26 (1455.18) mg]. Fruits [0.29±0.72 servings/day], vegetables [0.95±0.77 servings/day] and milk [0.24±0.38 servings/day] were below recommendations. Increased intake of meat and sodium were associated with higher BMI, waist circumference, body fat percentage, and visceral fat (p < 0.001). Greater intake of ultra-processed food was associated with high BMI (p = 0.009), waist circumference (p = 0.046), and visceral fat (p = 0.014). Besides, high sugar intake was associated with greater BMI (p = 0.003), body fat percentage (p = 0.020), and visceral fat (p = 0.027). CONCLUSIONS: Meat, sugar, sodium, and ultra-processed foods were high-risk foods associated with adiposity among young adults. There is a need to improve education and support to promote healthy eating for chronic disease prevention related to metabolic abnormalities.

Associations between Taste Perception Profiles and Empirically Derived Dietary Patterns: An Exploratory Analysis among Older Adults with Metabolic Syndrome

Taste perception is a primary driver of food choices; however, little is known about how perception of all five tastes (sweet, salt, sour, bitter, umami) collectively inform dietary patterns. Our aim was to examine the associations between a multivariable measure of taste perception—taste perception profiles—and empirically derived dietary patterns. The cohort included 367 community-dwelling adults (55–75 years; 55% female; BMI = 32.2 ± 3.6 kg/m2) with metabolic syndrome from PREDIMED-Plus, Valencia. Six taste perception profiles were previously derived via data-driven clustering (Low All, High Bitter, High Umami, Low Bitter and Umami, High All But Bitter, High All But Umami); three dietary patterns were derived via principal component analysis (% variance explained = 20.2). Cross-sectional associations between profiles and tertials of dietary pattern adherence were examined by multinomial logistic regression. Overall, there were several significant differences in dietary pattern adherence between profiles: the vegetables, fruits, and whole grains pattern was significantly more common for the High All But Umami profile (OR range for high vs. low adherence relative to other profiles (1.45–1.99; 95% CI minimum lower, maximum upper bounds: 1.05, 2.74), the non-extra virgin olive oils, sweets, and refined grains pattern tended to be less common for Low All or High Bitter profiles (OR range: 0.54–0.82), while the alcohol, salty foods, and animal fats pattern tended to be less common for Low Bitter and Umami and more common for High All But Bitter profiles (OR range: 0.55–0.75 and 1.11–1.81, respectively). In conclusion, among older adults with metabolic syndrome, taste perception profiles were differentially associated with dietary patterns, suggesting the benefit of integrating taste perception into personalized nutrition guidance.

Moving towards a Healthier Dietary Pattern Free of Ultra-Processed Foods

In recent years, ultra-processed food (UPF) intake has increased worldwide, representing almost 60% of total dietary intake in several countries such as the USA and the UK, and around 17 to 24% in the Mediterranean countries, such as Spain and Italy, respectively [...]

Usefulness and effectiveness of locally available food that can improve gut health using mHealth: Audio-based Intervention for Malnourished Children living in tribal settings Rajasthan (AIM-Children) (Preprint)

BACKGROUND Child malnutrition is a major global health problem that imposes morbidity and mortality burdens. Malnutrition has long-term effects on gut health which can affect the development of children. Gut microbes play a crucial role in the absorption of nutrients in food. Improving mothers’ awareness regarding gut health is one of the many ways to strengthen against diarrheal conditions and malnutrition among children. OBJECTIVE The objectives of the present study are to design, develop and evaluate a mobile-based intervention to improve gut health through mHealth. The study will further explore the association between socio-demographic characteristics, health status, dietary pattern of child and Water and Sanitation Hygiene Practice (WASH) related knowledge, attitude, practices of a mother living in tribal of Sikar, Rajasthan. METHODS A quasi-experimental randomized trial will be conducted between November 2021 and February 2022. 150 mothers of Moderate Acute Malnutrition (MAM) children will be recruited and enrolled using a non-probability complete enumeration sampling method from the Sapera, Loharu, and Banjara community of Sikar. The study participants will be randomized into two groups: Intervention (mobile linked audio-based messages); and Control group (no-mobile linked audio-based messages). Differences in the dietary pattern of children, mothers’ WASH-related knowledge, attitudes, and practices will be measured across the group. The data will be collected for the focus group, baseline, timeline 1 (after one month of the baseline) and timeline 2 (after one month of timeline 1). The study outcomes include the change in KAP of mothers pre- and post-intervention. RESULTS The study's results will help assess the usefulness and effectiveness of the proposed design and development of a user-centered informatics platform that can deliver multimedia-driven nutrition and health educational modules tailored to facilitate healthy habits and improvement in gut health in children of tribal settings. CONCLUSIONS The study will provide insights toward the barriers and challenges leading to malnutrition and poor gut health of the children in tribal populations and the relationship between gut health and malnutrition in the children. We anticipate that the intervention group will show a significant change in improvement in gut health, dietary pattern, WASH practices, knowledge, attitude, and practice of mother. CLINICALTRIAL Ethical approval was obtained from the UREC (University Research Ethics Committee) of DIT University, Dehradun, Uttarakhand, India (DITU/UREC/2021/07/6).

As a Staple Food Substitute, Oat and Buckwheat Compound Has Health-Promoting Effects for Diabetic Rats

Dietary intervention is crucial for the prevention and control of diabetes. China has the largest diabetic population in the world, yet no one dietary strategy matches the eating habits of the Chinese people. To explore an effective and acceptable dietary pattern, this study uses oat and buckwheat compound (OBC) as a staple food substitute and explored its effects on diabetic Sprague–Dawley rats. The model of diabetic rats was established by combining high-calorie feed and streptozotocin (STZ) injection. The dietary intervention for the seven groups, including a normal control group, a model control group, a metformin control group, a wheat flour control group, and three OBC groups with different doses, started from the beginning of the experiment and lasted for 11 weeks, two consecutive injections of STZ in small doses were operated at the 6th week. General states, glucose metabolism, and lipid metabolism indexes were measured. Antioxidant and inflammatory indexes and pathologic changes of kidney and liver tissues were tested. Changes in kidney and ileum ultramicrostructure were detected. What's more, ileal epithelial tight junction proteins and gut microbiota were analyzed. Significant decreases in fasting blood glucose (FBG), glucose tolerance, serum insulin, and insulin resistance were observed in rats intervened with OBC, and these rats also showed a higher level of superoxide dismutase (SOD) together with improved lipid metabolism, attenuated inflammation, and liver and kidney injuries. In addition, in OBC groups, the intestinal barrier was improved, and the disturbance of gut microbiota was reduced. These results suggest that OBC has health-promoting effects for diabetic rats, and since oat and buckwheat are traditionally consumed grains in China, OBC could be a potential and easy-to-accept staple food substitute for the dietary pattern for Chinese.
