Turmeric, Pepper, Cinnamon, and Saffron Consumption and Mortality

Area of Science:

• Epidemiology
• Nutritional Science
• Public Health

Background:

• Previous research suggests spices positively impact lipid profiles, glucose, and blood pressure.
• These factors are linked to cardiovascular disease (CVD), diabetes mellitus, and mortality.
• This study examines the association between specific spice consumption and mortality risk.

Purpose of the Study:

• To evaluate the relationship between consuming turmeric, black/chili pepper, cinnamon, and saffron with overall and cause-specific mortality.
• To analyze mortality data from a large adult population in Iran.

Main Methods:

• Utilized data from the Golestan Cohort Study (n=44,398) aged 40-75 years.
• Extracted spice consumption data using a baseline Food Frequency Questionnaire.
• Employed Cox models to estimate hazard ratios (HR) for mortality, adjusting for confounders over an 11-year follow-up.

Main Results:

• Turmeric consumption showed a reduced risk of overall (HR=0.90) and CVD mortality (HR=0.91).
• Black or chili pepper consumption was linked to reduced overall mortality risk (HR=0.91).
• Saffron consumption was associated with significantly lower overall (HR=0.85) and CVD mortality (HR=0.79).
• No significant associations were found for cinnamon consumption or cancer mortality.

Conclusions:

• Turmeric and saffron consumption are associated with a decreased risk of overall and cardiovascular mortality.
• The findings support the hypothesis of a protective effect of certain spices on mortality.
• Further prospective studies are needed to confirm these associations.
