Behavioral Economics in Health Snack Choices: Nudges and Consumer Decision-Making
Overview
This paper analyzes why consumers choose tasty but unhealthy snacks over nutritious options using behavioral economics frameworks. It examines cognitive biases such as present bias, loss aversion, and status quo bias, then proposes practical nudge interventions to encourage healthier choices while preserving consumer autonomy.

Behavioral Economics in Health Snack Choices
Consumers frequently choose tasty but less healthy snacks over nutritious options despite knowing the long-term benefits. Traditional economic theory assumes rational utility maximization based on prices, income, and preferences, but behavioral economics provides a more accurate framework for this “health vs. taste” conundrum. Present bias causes consumers to heavily discount future health gains while overvaluing immediate sensory pleasure from taste (Shapiro et al., 2023). The loss aversion reinforces this: giving up enjoyable snacks feels like a painful loss, outweighing the perceived gain of better nutrition. Mental accounting further distorts choices, where consumers treat “treat money” or impulse purchases differently from “health money,” justifying indulgent buys even when budgets are tight. Status quo bias locks in familiar, tasty brands, making switching to unfamiliar organic snacks feel risky or effortful.
In Nairobi, middle-income consumers face this bias strongly. Limited disposable income heightens price sensitivity, making cheaper, tastier snacks (like fried crisps) more attractive substitutes. The substitution effect favors them (higher perceived utility per shilling), while the income effect limits healthier choices when organic prices are higher (Shapiro et al., 2023). Behavioral economics reveals that rational models overlook these emotional and cognitive factors, leading to suboptimal decisions that prioritize short-term taste over long-term health.
