The Estimated Health Impact of Poor Diets (BBC News / Lancet / NHS Digital)

Summary

Poor diet has been estimated to be a bigger killer than smoking. Malnutrition (resulting from poor quality diets) may play a role in one in five premature deaths world-wide; an estimated 11 million people. The most dangerous diets contain:

• Excess salt; calculated to be involved in an estimated three million deaths.
• Insufficient whole grains; calculated to be involved an estimated three million deaths.
• Insufficient fruit; calculated to be involved an estimated two million deaths.
• Insufficient consumption of nuts, seeds, vegetables, omega-3 (seafood) and fibre are other common features of bad diets contributing to premature mortality.
