To tackle the global rise in non-communicable diseases, researchers urge the G20 to support stronger health taxes on harmful products like sugary drinks, tobacco, alcohol, and ultra-processed foods.
By 2030, non-communicable diseases (NCDs) such as diabetes, cancer, and heart disease will account for 75% of all global deaths—most in low- and middle-income countries. In a recent article for The Conversation, Professors Karen Hofman and Susan Goldstein from the University of the Witwatersrand call on G20 countries to take bold action by supporting health taxes on harmful products like sugary drinks, tobacco, alcohol, and ultra-processed foods.
Drawing on decades of research, the authors point to the “commercial determinants of health” as key drivers of these health crises. Aggressive marketing strategies—especially targeted at children—have helped normalise the consumption of unhealthy products. Despite some progress, industry lobbying continues to undermine health policies, diluting their effectiveness.
The authors argue that price increases via taxation are among the most effective tools to reduce consumption. A 50% tax increase on tobacco, alcohol, and sugary beverages could generate $3.7 trillion globally over five years and save 50 million lives over five decades.
As South Africa leads the G20 health agenda, Hofman and Goldstein call for the group to champion preventative health strategies, strengthen policy frameworks, and hold corporations accountable—placing public health before profit.
