“…The discussion whether coffee can be claimed as an actual functional food is ongoing and there is not enough long-term evidence that coffee can prevent disease. Therefore coffee consumption for health reasons requires further scientific evidence before being recommended and promoted [7,28,114].…”

Coffee is popular worldwide and consumption is increasing, particularly in non-traditional markets. There is evidence that coffee consumption may have beneficial health effects. Consumers’ beliefs in the health benefits of coffee are unclear. The study aimed at analyzing consumers’ perceptions of coffee health benefits, consumption and purchasing motives of coffee consumers with positive perceptions of coffee health benefits, and willingness to pay for coffee with associated health claims. Data were collected through a face-to-face survey with consumers, resulting in a convenience sample of 250 questionnaires valid for data elaboration. Results were elaborated with factor analysis and logistic regression analysis. Findings revealed that a relevant minority of consumers believed that coffee could have positive health effects. The consumer with a positive perception of coffee health benefits is mostly male, young, works, is familiar with non-espresso-based coffee, consumes a limited amount of coffee (generally not for breakfast and often in social settings), and buys coffee at retail outlets. Consumers drink coffee for its energetic and therapeutic effects. Coffee consumption is still price-driven, but consumers are interested in purchasing coffee with associated health claims. There is the opportunity to improve the perception of coffee health benefits in consumers’ minds.

“…cardiovascular disease, metabolic disorder, age-related neurodegeneration), and coffee consumption is but one among numerous variables of lifestyle and environment that may be implicated. There is agreement that many factors, beneficial or harmful, may confound the relatively weak coffee-health associations reported in the observational literature (Guallar, 2017), and in any given study there can be no assurance that the correct factors have been chosen or that the correct amount of statistical 'adjustment' has been applied. Taking account of the absence of consensus regarding confounder selection, the fact that the direction (and not merely the size) of observational associations is subject to reversal depending upon which putative confounders are included or omitted renders firm conclusions impossible.…”

Are coffee’s alleged health protective effects real or artifact? The enduring disjunction between relevant experimental and observational evidence

When considered in the context of experimental evidence concerning caffeine's known pharmacological actions, there is reason to be sceptical about observational findings alleging health-protective effects from coffee consumption. Long-term randomised trials are needed to end the enduring interpretative disjunction between observational and experimental evidence concerning coffee/caffeine consumption and health.
