## Summary

U.S. adults with higher blood levels of vitamin C, vitamin D, beta-carotene, and lycopene were less likely to die during the study. Part of the reason seemed to be slower biological aging. Lycopene, found in tomatoes, had the strongest link. This is a correlation, so it doesn't prove the nutrients caused the benefit.

## Practical Takeaway

This study suggests diets rich in colorful produce and vitamin D may support longer life.
