•Differences in emotional responses to sweet foods were observed according to sweet liker status.•Sweet likers elicited strong positive emotions when consuming highly sweet and preferred ...samples.•Sweet dislikers elicited positive emotions to the highly preferred samples regardless of sweetness.
Sweetness is usually associated with positive affect, but it is known that there are systematic individual variations in the degree of pleasantness of sweet tastes. These variations are thought to be important in determining food preferences. The objectives of this study were to classify people according to sweet liker status, and to examine how they expressed emotions to foods varying in sweetness. The samples used in the study were four commercial products: two beverages (OD and MJ) and two biscuits (WB and CB), each pair differing in sweetness. Subjects were asked to rate their liking for the samples and any emotions elicited by them immediately after they consumed each of the products. Sweet likers (SL) and sweet dislikers (SD) were selected by hierarchical cluster analysis based on hedonic responses to the five concentrations of sucrose solution. SL expressed strong positive emotions in response to the CB and MJ, which were both highly sweet and highly liked by SL. However, they expressed relatively strong negative emotions to the far less sweet OD. In contrast, SD expressed relatively strong positive emotions to WB and MJ which were both liked, while they neither were positive about, nor liked, CB. This study clearly shows that emotional responses are subject to similar individual variations to sweet foods as are measures of liking. In turn, sweet liker status can be shown to be associated with varied emotional states elicited by foods varying in sweetness.
Colorectal cancer (CRC) incidence has increased among patients aged <50 years. Exploring high-risk factors and screening high-risk populations may help lower early-onset CRC (EO-CRC) incidence. We ...developed noninvasive predictive models for EO-CRC and investigated its risk factors.
This retrospective multicenter study collected information on 1756 patients (811 patients with EO-CRC and 945 healthy controls) from two medical centers in China. Sociodemographic features, clinical symptoms, medical and family history, lifestyle, and dietary factors were measured. Patients from one cohort were randomly assigned (8:2) to two groups for model establishment and internal validation, and another independent cohort was used for external validation. Multivariable logistic regression, random forest, and eXtreme Gradient Boosting (XGBoost) were performed to establish noninvasive predictive models for EO-CRC. Some variables in the model influenced EO-CRC occurrence and were further analyzed. Multivariable logistic regression analysis yielded adjusted odd ratios (ORs) and 95% confidence intervals (CIs).
All three models showed good performance, with areas under the receiver operator characteristic curves (AUCs) of 0.82, 0.84, and 0.82 in the internal and 0.78, 0.79, and 0.78 in the external validation cohorts, respectively. Consumption of sweet (OR 2.70, 95% CI 1.89-3.86, P < 0.001) and fried (OR 2.16, 95% CI 1.29-3.62, P < 0.001) foods ≥3 times per week was significantly associated with EO-CRC occurrence.
We established noninvasive predictive models for EO-CRC and identified multiple nongenetic risk factors, especially sweet and fried foods. The model has good performance and can help predict the occurrence of EO-CRC in the Chinese population.
We evaluated changes in mindful eating as a potential mechanism underlying the effects of a mindfulness-based intervention for weight loss on eating of sweet foods and fasting glucose levels. We ...randomized 194 obese individuals (
M
age = 47.0 ± 12.7 years; BMI = 35.5 ± 3.6; 78 % women) to a 5.5-month diet-exercise program with or without mindfulness training. The mindfulness group, relative to the active control group, evidenced increases in mindful eating and maintenance of fasting glucose from baseline to 12-month assessment. Increases in mindful eating were associated with decreased eating of sweets and fasting glucose levels among mindfulness group participants, but this association was not statistically significant among active control group participants. Twelve-month increases in mindful eating partially mediated the effect of intervention arm on changes in fasting glucose levels from baseline to 12-month assessment. Increases in mindful eating may contribute to the effects of mindfulness-based weight loss interventions on eating of sweets and fasting glucose levels.
•Liking for sweet foods is not associated with Canadian Healthy Eating Index (C-HEI).•Liking for salty foods is associated with lower consumption of healthy foods.•Liking for salty foods is inversely ...associated with C-HEI in men.•Liking for salty foods is inversely associated with C-HEI in less educated women.
The research aimed at examining how liking for foods high in salt and fat and for foods high in sugar are associated with overall diet quality and how these associations differ according to individual characteristics (i.e., sex, age, education, income, nutrition knowledge, and energy reporting status) in French-speaking adults from the Province of Quebec, Canada. As part of the web-based cross-sectional PREDISE study, 1096 men and women completed online questionnaires. The Food Liking Questionnaire assessed reported liking for a variety of salty foods (high in salt and fat) and sweet foods (high in sugar and either high-fat or low-fat) on a scale from 1 to 9. The Canadian Healthy Eating Index (C-HEI) was computed based on data collected using 24-hour food recalls. Women (vs. men) reported lower liking for salty foods (5.97 ± 1.34 vs. 6.58 ± 1.16, p < 0.0001) and for sweet foods (5.52 ± 1.36 vs. 5.71 ± 1.25, p = 0.015). Multiple linear regressions showed that liking for sweet foods was not associated with C-HEI (B = −0.10, p = 0.78). Given a significant sex interaction in the association between liking for salty foods and C-HEI (p interaction = 0.0218), subsequent analyses were stratified by sex. Multiple linear regressions supported that liking for salty foods was more strongly inversely associated with C-HEI in men (B = −3.37, p < 0.0001) than women (B = −1.46, p = 0.0035). In conclusion, a strong liking for salty foods may interfere with healthy eating, especially in men. Building on these results, future studies should investigate the potential of interventions designed to improve the healthiness of food habits in individuals with strong liking for these foods.
Sex differences in human brain structure and function are important, partly because they are likely to be relevant to the male–female differences in behavior and in mental health. To analyse sex ...differences in cortical function, functional connectivity was measured in 36,531 participants (53% female) in the UK Biobank (mean age 69) using the Human Connectome Project multimodal parcellation atlas with 360 well-specified cortical regions. Most of the functional connectivities were lower in females (Bonferroni corrected), with the mean Cohen’s d = − 0.18. Removing these as covariates reduced the difference of functional connectivities for females—males from
d
= − 0.18 to − 0.06. The lower functional connectivities in females were especially of somatosensory/premotor regions including the insula, opercular cortex, paracentral lobule and mid-cingulate cortex, and were correlated with lower maximum workload (
r
= 0.17), and with higher whole body fat mass (
r
= − 0.17). But some functional connectivities were higher in females, involving especially the ventromedial prefrontal cortex and posterior cingulate cortex, and these were correlated with higher liking for some rewards such as sweet foods, higher happiness/subjective well-being, and with better memory-related functions. The main findings were replicated in 1000 individuals (532 females, mean age 29) from the Human Connectome Project. This investigation shows the cortical systems with different functional connectivity between females and males, and also provides for the first time a foundation for understanding the implications for behavior of these differences between females and males.
Sweet foods occupy an ambiguous position in many people's diets, perhaps especially for children and adolescents. The twin expectation that they both covet and limit their intake can create a dilemma ...not only in the home, but also in the school subject Home Economics (HE), which among other themes has a focus on food and health. In this study, we explored how Discourses on sweet foods were formed, reproduced, and challenged during 26 lessons in northern Sweden. Overall, sweet foods were constructed as desirable but also as unhealthy, disgusting, and unnecessary. They were used as a form of capital where ownership, distribution, and fairness were important, and students could mark friendships by sharing and gifting. Conversely, they could also use sweet foods to police, ridicule, question, or punish each other. Conflicts could arise around less-than-perfect results and students could withhold sweet foods from each other as a form of social rejection. Vague limits to intake placed responsibility for intake on the students themselves. We suggest that a contextualisation of the social, cultural, and health aspects of sweet foods in HE might help students acquire a more holistic Discourse of sweet foods and mitigate their social weaponisation.
Abstract Palatable foods lead to overeating, and it is almost a forgone conclusion that it is also an important contributor to the current obesity epidemic – there is even talk about food addiction. ...However, the cause–effect relationship between taste and obesity is far from clear. As discussed here, there is substantial evidence for altered taste sensitivity, taste-guided liking and wanting, and neural reward processing in the obese, but it is not clear whether such traits cause obesity or whether obesity secondarily alters these functions. Studies with calorie restriction-induced weight loss and bariatric surgery in humans and animal models suggest that at least some of the obesity-induced alterations are reversible and consequently represent secondary effects of the obese state. Thus, both genetic and non-genetic predisposition and acquired alterations in taste and reward functions appear to work in concert to aggravate palatability-induced hyperphagia. In addition, palatability is typically associated with high energy content, further challenging energy balance regulation. The mechanisms responsible for these alterations induced by the obese state, weight loss, and bariatric surgery, remain largely unexplored. Better understanding would be helpful in designing strategies to promote healthier eating and prevention of obesity and the accompanying chronic disease risks.
Background: Sugar-sweetened beverage (SSB) intake is a substantial source of energy in the diet of US children.
Objective: We examined the associations between mothers’ child-feeding practices and ...SSB intake among 6-y-old children.
Methods: We analyzed data from the Year 6 Follow-up of the Infant Feeding Practices Study II in 1350 US children aged 6 y. The outcome variable was child’s SSB intake. The exposure variables were 4 child-feeding practices of mothers: setting limits on sweets or junk foods, regulating their child’s favorite food intake to prevent overconsumption, pressuring their child to eat enough, and pressuring their child to “clean the plate.” We used multinomial logistic regression and controlled for child and maternal centeracteristics. Analyses were stratified on child weight status.
Results: The consumption of SSBs ≥1 time/d was observed among 17.1% of underweight/normal-weight children and in 23.2% of overweight/obese children. Adjusted ORs (aORs) of consuming SSBs ≥1 time/d (vs. no SSB consumption) were significantly lower in children whose mothers reported setting limits on sweets/junk foods (aOR: 0.29; 95% CI: 0.15, 0.58 for underweight/normal-weight children; aOR: 0.16; 95% CI: 0.03, 0.79 for overweight/obese children). SSB intake was higher among underweight/normal-weight children whose mothers reported trying to keep the child from eating too much of their favorite foods (aOR: 2.03; 95% CI: 1.25, 3.29). Mothers’ tendency to pressure their children to consume more food or to “clean the plate” was not associated with child’s SSB intake.
Conclusions: SSBs were commonly consumed by young children. The odds of daily SSB intake were lower among children whose mothers set limits on sweets/junk foods regardless of child’s weight but were higher among underweight/normal-weight children whose mothers restricted the child’s favorite food intake. Future studies can investigate the impact of alternatives to restrictive feeding practices that could reduce children’s SSB intake.
The COVID-19 pandemic impacted some dietary habits of Americans.
We examined characteristics associated with a high intake of sweet foods and sugar-sweetened beverages (SSB) during the COVID-19 ...pandemic among US adults.
This was a cross-sectional study.
The SummerStyles survey data were collected in 2021 among 4034 US adults (≥18 years).
The frequencies were measured of consuming various sweet foods (chocolate/candy, doughnuts/sweet rolls/Danish/muffins/Pop-Tarts, cookies/cake/pie/brownies, and ice cream/frozen desserts) and SSB (regular sodas, sweetened coffee/tea drinks fruit drinks, sports drinks, and energy drinks) during the COVID-19 pandemic. The responses were categorized into 0, >0 to <1, 1 to <2, and ≥2 times/day. The descriptive variables were sociodemographics, food insecurity, weight status, metropolitan status, census regions, and eating habit changes during the COVID-19 pandemic.
Multinomial regressions were used to estimate adjusted odds ratios (AOR) for being a high consumer of sweet foods and SSB after controlling for characteristics.
During 2021, 15% of adults reported consuming sweet foods ≥2 times/day, and 30% reported drinking SSB ≥2 times/day. The factors that were significantly associated with greater odds of high sweet food intake (≥2 times/day) were lower household income (AOR = 1.53 for <$35,000 vs. ≥$100,000), often/sometimes experiencing food insecurity (AOR = 1.41 vs. never), and eating more sweet foods than usual since start of the pandemic (AOR = 2.47 vs. same as usual). The factors that were significantly associated with greater odds of high SSB intake (≥2 times/day) were males (AOR = 1.51), lower education (AOR = 1.98 for ≤high school; AOR = 1.33 for some college vs. college graduate), currently having children (AOR = 1.65), living in nonmetropolitan areas (AOR = 1.34), and drinking more SSB than usual since the pandemic began (AOR = 2.23 vs. same as usual). Younger age, Black race, and reductions in consumption during COVID-19 were related to lower sweet food and SSB intakes.
Our findings, which identified high consumers of sweet foods or SSB, can be used to inform efforts to reduce consumers' added sugars intake during pandemic recovery and support their health.
