The Impact

Food production is a major contributor to environmental damage. More environmentally sustainable foods could incur higher costs for consumers. In this review, we explore whether consumers are willing to pay (WTP) more for foods with environmental sustainability labels (‘ecolabels’). Six electronic databases were searched for experiments on consumers’ willingness to pay for ecolabelled food. Monetary values were converted to Purchasing Power Parity dollars and adjusted for country-specific inflation. Studies were meta-analysed and effect sizes with confidence intervals were calculated for the whole sample and for pre-specified subgroups defined as meat-dairy, seafood, and fruits-vegetables-nuts. Meta-regressions tested the role of label attributes and demographic characteristics on participants’ WTP. Forty-three discrete choice experiments (DCEs) with 41,777 participants were eligible for inclusion. Thirty-five DCEs (n = 35,725) had usable data for the meta-analysis. Participants were willing to pay a premium of 3.79 PPP$/kg (95%CI 2.7, 4.89, p ≤ 0.001) for ecolabelled foods. WTP was higher for organic labels compared to other labels. Women and people with lower levels of education expressed higher WTP. Ecolabels may increase consumers’ willingness to pay more for environmentally sustainable products and could be part of a strategy to encourage a transition to more sustainable diets.

Local Production

We use data from hypothetical and nonhypothetical choice-based conjoint analysis to estimate willingness to pay for local food products. The survey was administered to three groups: consumers from a buying club with experience with local and grass-fed production markets, a random sample of Maryland residents, and shoppers at a nonspecialty Maryland supermarket. We find that random-sample and supermarket shoppers are willing to pay a premium for local products but view local and grass-fed production as substitutes. Conversely, buying-club members are less willing to pay for local production than the other groups but do not conflate local and grass-fed production.

The Mediterranean

The purpose of this overview is to present the evidence that adherence to Mediterranean lifestyle components is beneficial for functional and cognitive health. Although Mediterranean diet is the principal component of this lifestyle, other components, like physical activity and socializing, form complex interactions and together they complete into the Mediterranean lifestyle. Individual components and their interactions have not been studied thoroughly, however, there is an increasing attention for these matters through scientific literature in original research, reviews and meta-analysis. This paper considers the recent knowledge and trends related to defining the indicators concerning these lifestyle components, as well as summarizes the health benefits induced by adherence to them and explains why Mediterranean lifestyle components are important for health.

The Status

Various effects of forest healing on health have been reported, but a certification system to assess the effectiveness of forest healing programs does not exist. In this study, a systematic review (SR) on the “health benefits of forests” and “meta-analysis of forest therapy” was conducted after analyzing the status and level of evidence of 75 forest healing programs that were conducted post-certification in South Korea. The SR for “health benefits of forests” distinguished between activities and time, resulting in 90.9% of walking activities for more than an hour under psychological health, and 100.0% of exercise activities for less than an hour under physiological health. However, the effect of indirect activities performed for more than an hour was unknown. Thus, we confirmed that many indoor activities in the field had low effect size or no established basis regarding the feasibility of its operation. The SR on “meta-analysis of forest therapy” to check whether the program was effective. The highest number of healing effects were obtained for blood pressure (32), followed by psychological depression (24). The findings of this can serve as baseline data to facilitate future development and dissemination of evidence-based forest healing programs.
