Plantlibra is an EU-funded research project about risks and benefits of plant food supplements.

Plant-based food supplements (PFS) have been and are increasingly used across the European Union, with ingredients often deriving from Third Countries. The knowledge on the safety and benefits of these products – particularly in Europe - is lagging behind the demands of the market and of regulators. Competent authorities, food chain operators and consumers often face difficulties in making informed decisions.

PlantLIBRA aims to foster safe use of food supplements containing or consisting of plants and/or herbal extracts, chiefly by increasing science-based decision-making by regulators and food chain operators, through data, information and tools. PlantLIBRA is structured to develop, validate and disseminate methodologies for risk and benefit assessment, to greatly expand, generate and make available knowledge on PFS, and implement sustainable international cooperation. Through the multi- disciplinary consortium of PlantLIBRA, researchers, excelling in different fields, will share their work and expertise among themselves and with the leading stakeholders towards an integrated "science of botanicals".

Ideas for consumer perception study

Question

What could be asked in the consumer perception study about the benefit-risk assessment?

Rationale

A benefit-risk assessment should be useful for some practical purpose. There are two possible uses: the authority uses it to make decisions about acceptability of health claims or products in the market; and the consumer uses it to make informed purchasing decisions. In this study we could and should test for how the consumer perceives the benefit-risk information depending on a) the outcome (i.e. clear vs unclear benefit) and b) way of expressing the conclusion.

Answer

The following table describes different pieces of user information that are used to inform the user about the net health benefits of a mock-up PFS product.

Different ways of describing benefit-risk information to a consumer.

Different ways of expressing outcomes	Different assessment outcomes
	Net benefit is high	Net benefit is zero
DALY estimates with uncertainties	According to a benefit-risk assessment, using this product for a year will bring more health worth 3 healthy days (uncertainty from 0 to 10 days).	According to a benefit-risk assessment, using this product for a year will bring more health worth 0.5 healthy days (uncertainty from –5 to 6 days).
Descriptive without uncertainty	According to a benefit-risk assessment, using this product will bring a small health benefit.	According to a benefit-risk assessment, using this product will bring a negligible health benefit.
Descriptive with uncertainty	According to a benefit-risk assessment, using this product will bring a small health benefit (result is uncertain and may be missing).	According to a benefit-risk assessment, using this product is as likely to produce a small health benefit as a small health harm.
