This study aimed to explore consumer perceptions and trends by deriving major keywords for diet before (2019) and after (2021) COVID-19 based on big data. To achieve this, data were collected by social media and text mining. In addition, semantic network, network visualization, and sentiment analyses were conducted. Text mining analysis showed keywords with the highest frequencies before and after COVID-19 were exercise, diet, start, health, and effect. TF-IDF (term frequency-inverse document frequency) analysis showed keywords with high scores before COVID-19 were lunch boxes, diary, dinner, efficacy, food, and summer and that dance, sales, and products appeared only before COVID-19. On the other hand, TF-IDF after COVID-19 showed recommendations, snacks, delicious, food, salad, care, making, and weight were used more frequently and that new words such as shake, cooking, and protein featured more after COVID-19. After COVID-19, consumers showed more interest in snacks and food that can be made and eaten rather than dietary supplements. Semantic network analysis showed that before COVID-19, preparation, management, health, and summer had high frequencies, whereas after COVID-19, keywords such as maintenance, control, weight, management, and weight loss appeared. These findings show that the purpose of diet before COVID-19 was to improve health and summer preparation, but that after COVID-19, consumer focus changed to weight loss and maintenance. The findings of this study provide fundamental data for in-depth marketing and consumer research studies for diet-related industries and academia.

“…Obesity, which arises from an imbalance of energy intake and expenditure, has a tremendous socioeconomic impact at an epidemic level. The World Health Organization (WHO) reported that two billion people suffer from obesity [ 1 , 2 ]. Obesity causes numerous complications such as hypertension, gallbladder disease, cardiovascular disease, heart failure, coronary artery disease, and stroke [ 3 , 4 ].…”

Polydimethyl-siloxane (PDMS) is often applied to fabricate cell chips. In this study, we fabricated an adipocyte microcell pattern chips using PDMS to analyze the inhibition activity of lipid droplets in mouse embryo fibroblast cells (3T3-L1) with anti-obesity agents. To form the PDMS based micropattern, we applied the micro-contact printing technique using PDMS micro-stamps that had been fabricated by conventional soft lithography. This PDMS micro-pattern enabled the selective growth of 3T3-L1 cells onto the specific region by preventing cell adhesion on the PDMS region. It then allowed growth of the 3T3-L1 cells in the chip for 10 days and confirmed that lipid droplets were formed in the 3T3-L1 cells. After treatment of orlistat and quercetin were treated in an adipocyte micro-cell pattern chip with 3T3-L1 cells for six days, we found that orlistat and quercetin exhibited fat inhibition capacities of 19.3% and 24.4% from 0.2 μM of lipid droplets in 3T3-L1 cells. In addition, we conducted a direct quantitative analysis of 3T3-L1 cell differentiation using Oil Red O staining. In conclusion, PDMS-based adipocyte micro-cell pattern chips may contribute to the development of novel bioactive compounds.

BACKGROUND: Obesity is a growing global problem and an efficient screening method to discover anti-obesity agents on a simple platform is needed. Polydimethylsiloxane (PDMS)-based micro-cell chips are widely applied to cell studies because of their non-toxicity and biocompatibility. RESULTS: 3T3-L1 cells were cultured on a micro-cell pattern chip. After 6 days, we successfully observed adipocyte differentiation in 3T3-L1 cells within the micro-cell pattern chip. Next, 3T3-L1 cells on the micro-cell patterned chip were then treated under various concentrations of glycitein and 7,3 ′ ,4 ′ -trihydrxyisoflavone (0.2, 0.5 and 1.0 mol L −1 ) for 10 days. Glycitein and 7,3 ′ ,4 ′ -trihydrxyisoflavone exhibited a fat inhibitory capacity of higher than 36% and 44% at 1.0 mol L −1 in 3T3-L1 adipocytes, suggesting anti-obesity activity. It was demonstrated that this platform can be used for real-time monitoring of cell growth and differentiation in live cell-based lipid droplets inhibition activity. CONCLUSION: A micro-cell pattern chip was made using PDMS microstamps through micro-molding for an efficient, rapid, and reliable cell selective patterning of 3T3-L1 cells differentiation. The present work provides a proof-of-principle demonstration of the direct qualitative and quantitative analysis of adipocyte differentiation through a simple microscopic observation of OilRed O staining for lipid droplets in cell array patterning. PDMS based micro-cell pattern chips can be used for the screening of anti-obesity agents such as glycitein and 7,3 ′ ,4 ′ -trihydrxyisoflavone. Furthermore, it is expected that micro-cell pattern chip technology could be applied to the development of novel bioactive compounds.
