A Systematic Review of the Sources of Dietary Salt Around the World

Published in Advances in Nutrition, Bhat et al conducted a global systematic review of dietary salt sources. Between 1975 and 2018, 80 studies (74 peer-reviewed) from 34 countries were identified. Discretionary sources of salt contributed to more than half daily intake in at least eight countries, and more than a quarter of daily intake in a further five countries. An inverse correlation was found between discretionary salt intake and a country’s GDP per capita (-8.7% discretionary salt per $10,000 GDP per capita). Bread and bakery products, cereal and grain products, meat products and dairy products were the top contributors to salt intake in most countries. To read more, click here.
