Purpose Anchored on the natural resource-based view and stakeholder theories, this study aims to investigate the mediating roles of sustainable supply chain management and green radical product innovation (GRPI) in the link between sustainable entrepreneurial orientation (SEO) and sustainability performance. Design/methodology/approach The comprehensive research model developed in this study is empirically tested by using data garnered from 248 managers of Ghanaian small and medium-sized enterprises. Partial least square structural equation modeling is applied as the methodological technique to test all the hypothesized relationships. Findings Results of the study indicate that SEO has a direct significant positive impact on environmental performance and social performance but not financial performance. However, through sustainable supply chain management and GRPI (both mediating variables), SEO tends to have significant impact on all sustainability performance dimensions (environmental, financial and social performance). Originality/value This study offers fresh empirical evidence by developing a unified research model that validates the specific mediation role of sustainable supply chain management between SEO and green radical product innovation, as well as the mediating roles of both sustainable supply chain management and GRPI between SEO and sustainability performance dimensions.

The World Health Organization (WHO) has highlighted the beneficial role of adequate intake of potassium (K) in combating the global burden of noncommunicable diseases (NCDs), mainly hypertension and cardiovascular diseases. Diets are the main source of K supply to humans and can contribute to both K deficiency (hypokalemia) and excess (hyperkalemia). While global attention is currently devoted to K deficiency, K excess can be even more dangerous and deserves equal attention. The objectives of this paper were to (i) estimate the K intake of Ghanaian population using food supply and food composition data and (ii) compare this estimate with the WHO-recommended requirement for K in order to assess if there is a risk of inadequate or excess K intake. Food supply data (1961–2011) were obtained from the Food Balance Sheet (FBS) of the Food and Agriculture Organization of the United Nations to derive trends in food and K supply. The average food supply in the FBS for 2010 and 2011 was used in assessing the risk of inadequate or excess dietary intake of K. The K content of the food items was obtained from food composition databases. Based on 2010-2011 average data, the K supply per capita per day was approximately 9,086 mg, about 2.6-fold larger than the WHO-recommended level (3,510 mg). The assessment suggests a potentially large risk of excess dietary K supply at both individual and population levels. The results suggest the need for assessing options for managing K excess as part of food security and public health strategies. The results further underscore a need for assessment of the K status of staple food crops and mixed diets, as well as K management in food crop production systems in Ghana.

Adequate dietary intake of potassium (K) helps fight noncommunicable diseases (NCDs), mainly hypertension and cardiovascular diseases. This paper (i) estimated the K intake of Ghanaian population using food supply and food composition data and (ii) compared this estimate with the WHO recommended requirement for K in order to assess if there is a risk of inadequate K intake. Food supply data (1961–2011) was obtained from the FAO Food Balance Sheet (FBS) to derive trends in food and K supply. The average food supply in the FBS for 2010 and 2011 was used in assessing the risk of inadequate dietary intake of K. The K contents of the food items were obtained from food composition databases. The mean K supply per capita per day was approximately 856 mg. The assessment suggests a potentially large risk of inadequate dietary K supply at both individual and population levels. The results suggest the need for assessing options for managing K deficiency, including assessment of K supplying power of soils and K fertilizer management in food crop production systems, as well as empirical estimates of K content of food items (including those underreported in the FBS) and mixed diets in Ghana.
