“…As shown in Table 3, none of these papers point clearly to adverse effects, while they are split between positive findings (four studies), and mixed findings/no evidence of an effect (five studies) 27 . Across the studies finding positive effects, the benefits include healthier diet (Clark et al, 2020; Palazzolo & Pattabhiramaiah, 2021) as well as lower obesity (indirect evidence, from Meltzer & Chen, 2011), as well as reduced stunting (in developing countries, in Ponce et al, 2018). The Palazzolo and Pattabhiramaiah (2021) and Ponce et al (2018) papers are more convincing; despite some weaknesses, they have the basic ingredients of what is needed for a causal analysis—both a panel data approach, and comparisons between those more and less affected.…”
