Factors Affecting Food and Nutrition: Understanding the Influences on Dietary Choices

The relationship between income and diet quality is well-documented. Low-income households face several compounding barriers: (1) Energy-dense processed foods (biscuits, instant noodles, refined grains) cost 3–5 times less per calorie than fresh fruits and vegetables — a purely rational economic choice when budget is constrained; (2) Time poverty — longer working hours and commutes leave less time for cooking; packaged foods are faster; (3) Food deserts — lower-income urban areas in India often lack nearby vegetable markets and fresh produce availability, particularly in tier-2 cities; (4) Storage limitations — households without refrigeration cannot buy perishables in bulk. A 2019 PHFI study found that the healthiest diets in India cost ₹150–200/person/day, unaffordable for households below ₹5,000/month. Government programmes like PM Poshan (mid-day meals), Anganwadi nutrition, and PDS rations partially address this but typically cover only staple calories, not micronutrient adequacy.

Stress triggers cortisol release, which increases cravings for high-calorie, high-fat, and high-sugar foods — this is a biological survival mechanism (cortisol signals the body to replenish energy stores). Chronic stress leads to: (1) Emotional eating — using food to regulate mood rather than hunger; (2) Binge eating episodes, particularly on 'forbidden' foods; (3) Irregular meal patterns that disrupt hunger hormones (ghrelin/leptin); (4) Preference for ultra-processed foods, which provide fast dopamine release. Depression specifically reduces motivation to cook and can cause either appetite loss or overeating. The gut-brain axis means poor diet (especially low fibre, high sugar) worsens mood and anxiety through disrupted serotonin production (90% of serotonin is made in the gut). Breaking the cycle: mindful eating practices, regular meal times (even simple ones), and addressing the underlying stressor are more effective than dietary willpower alone.

India's food culture has built-in nutritional strengths: plant-based staples (dal, sabzi, curd), fermented foods (idli, dosa, kanji), seasonal eating, and spice use with documented medicinal value (turmeric, cumin, coriander). However, cultural factors also create challenges: (1) Deep-fried festival foods and ritual sweets are socially non-negotiable for many families; (2) Hospitality norms mean refusing food at social gatherings is offensive — portion control is socially difficult; (3) Gender roles — women often eat last and least in rural households; (4) Rapid urbanisation — urban Indians are shifting from traditional home-cooked meals to street food and packaged snacks faster than any previous generation. A 2020 NFHS-5 finding: urban Indian adults have worse nutrition indicators (overweight/obesity rates 2–3× rural), paradoxically, because ultra-processed food access has increased faster than nutrition literacy.

Food marketing disproportionately promotes ultra-processed products — biscuits, instant noodles, packaged snacks, carbonated beverages. In India, advertising spend on packaged foods dwarfs public nutrition education budgets by approximately 100:1. Specific mechanisms of harm: (1) Children are the primary target — cartoon characters, celebrity endorsements, and school-adjacent advertising build brand preference before nutritional literacy develops; (2) Health halos — terms like 'baked not fried,' 'fortified with vitamins,' 'multigrain,' and 'natural' mislead consumers into thinking unhealthy products are nutritious (FSSAI has issued guidelines but enforcement is limited); (3) Availability heuristics — products that are heavily advertised are perceived as more normal and acceptable to eat frequently. Counter-evidence: the tobacco advertising ban in India reduced smoking rates measurably; similar evidence exists for junk food advertising restrictions near schools in Chile and UK. Practical advice: read the nutrition label (look for total sugar per 100g — above 15g per 100g is a red flag); ignore front-of-pack marketing claims.
