Study Notes
Major Determinants of Food Choice
- Food choices are driven not only by hunger but also by biological, economic, physical, social, psychological, and knowledge factors.
- Biological determinants include hunger, appetite, and taste, influencing what foods are selected.
- Economic and physical determinants encompass cost, income, availability, access, education, and cooking skills.
- Social influences involve culture, family, peers, and social contexts impacting eating behavior.
- Psychological factors such as mood and stress significantly shape individual food choices and habits.
Biological Determinants: Hunger and Satiety
- Hunger signals the need for food; satiety indicates the satisfaction after eating.
- Nutrients have varying satiating effects: protein is the most satiating, followed by carbohydrates, with fat being the least.
- Low energy density foods lead to greater satiety, while high-energy foods can promote unintended overeating due to lower awareness of portion sizes.
Biological Determinants: Palatability
- Palatability relates to the pleasure derived from food based on its sensory properties (taste, smell, texture).
- High palatability leads to increased food intake; the effects on appetite post-consumption are less clear.
- A greater variety of food can enhance intake and alter energy balance in the short term.
Biological Determinants: Sensory Aspects
- 'Taste' impacts food behavior and is derived from sensory stimulation including taste, smell, and texture.
- Innate preferences for sweetness and aversions to bitterness influence food choices from infancy.
- Food experiences shape taste preferences and aversions over time.
Economic and Physical Determinants: Cost and Accessibility
- Food cost is a primary factor influencing choices, particularly for low-income households prone to unbalanced diets.
- Accessibility to shops and healthy food options also plays a crucial role in dietary decisions.
- Higher food prices in urban areas can deter consumption of healthy foods like fruits and vegetables.
Economic and Physical Determinants: Education and Knowledge
- Higher education levels are linked to better dietary behaviors; however, knowledge alone doesn't ensure healthy choices.
- Conflicting nutrition information can lead to confusion and reluctance to act on dietary knowledge.
- Consistent messaging from trusted sources is essential for effective dietary education.
Social Determinants: Influence of Social Class
- Food patterns differ significantly across social classes, affecting nutrient intake and health outcomes.
- Poor diets are linked to both under-nutrition and over-nutrition, necessitating tailored interventions.
Social Determinants: Cultural Influences
- Cultural norms dictate food habits, including preparation traditions and dietary restrictions.
- Individuals may adapt to local food practices when moving to new cultural environments.
Social Determinants: Social Context
- Social interactions impact food choices, both directly (purchase decisions) and indirectly (observational learning).
- Social support enhances healthy eating, and family dynamics significantly shape food decisions and habits.
Social Determinants: Social Setting
- Increasing amounts of food are consumed outside the home, affecting availability and choice.
- Healthy options become critical in workplace and school settings, where access is often limited.
Meal Patterns
- Different motivations exist for various eating occasions; snacking can influence overall energy and nutrient intake.
- Healthy snack options are essential for encouraging better eating habits among youths.
Psychological Factors: Stress
- Psychological stress alters food choices, with varied effects on eating behavior depending on individual responses.
- Stress can lead to changes in eating patterns, potentially increasing weight gain risks if unmanaged.
Psychological Factors: Mood
- Food can affect mood, with emotional states influencing dietary choices.
- Cravings may intensify under stress or certain emotional conditions, particularly in women.
Eating Disorders
- Eating behavior is often conscious and subject to cognitive controls, which can lead to extreme dieting practices.
- Eating disorders stem from a mix of biological, psychological, and socio-cultural factors, requiring comprehensive treatment approaches.
Consumer Attitudes and Beliefs
- Consumer perceptions regarding diet, safety, and nutrition influence food choices and the effectiveness of health initiatives.
- Factors such as quality, taste, and health consciousness vary in importance across different demographics.
Optimistic Bias
- Many individuals overestimate the healthiness of their diets, resulting in a lack of motivation to change.
- Increasing awareness of dietary gaps and misconceptions can encourage healthier eating behaviors.
Barriers to Dietary and Lifestyle Change
- Cost is a significant barrier for low-income consumers, limiting exposure to new or healthier foods.
- Time constraints drive preferences for convenience foods, underscoring a need for affordable, healthy options.
Health Behavioural Models
- Understanding decision-making processes is crucial for effective health promotion strategies and interventions.### Health Behavior Models
- Health Belief Model (HBM) predicts protective health behavior (screening, vaccination, compliance) based on perceived threat and cost-benefit analysis.
- People require cues to action for behavioral change in health-related decisions.
- Theory of Reasoned Action (TRA) and Theory of Planned Behavior (TPB) emphasize that behavioral intention is the best predictor of behavior, determined by attitudes, social pressure, and perceived control.
- TRA successfully explains dietary intakes of fat and salt; TPB provides insight into beliefs about starchy foods.
Stages of Change Model
- Developed by Prochaska, it posits five stages for health behavior change: pre-contemplation, contemplation, preparation, action, and maintenance.
- Tailored interventions matching individuals' stage of change are suggested for effective behavior change.
- Popular for practical guidance in behavior modification; not fully explained by any single model.
- Most effective in discrete behaviors (e.g., consuming fruits/vegetables) rather than complex dietary changes.
Successful Interventions
- Dietary change is challenging due to entrenched lifelong habits; targeted interventions show variable success based on specific group needs.
- Supermarket interventions (e.g., shop tours, point-of-purchase information) raise awareness, with unclear impacts on long-term behavior change.
- School interventions increased children's fruit and vegetable intake through multimedia and hands-on involvement in food preparation.
- Workplace interventions successfully enhanced fruit/vegetable availability and price incentives for healthier snacks.
- Combining nutrition education with workplace changes is more effective, especially with sustained interactive activities.
Conclusion
- Influences on food choice provide multiple intervention opportunities, but barriers to dietary change vary by individual or group.
- Tailored strategies are essential to trigger behavior change considering different priorities.
- Campaigns with practical solutions and environmental changes are likely to succeed in facilitating dietary improvements.
