Tomato intake and Plasma/Serum Lycopene
- Consumption of tomatoes increases the level of serum lycopene
- Shown to increase after single serving, 24 h (1 study)
- Shown to increase after 1-week supplementation (diet or extract)
- Consumption of tomatoes will also increase tissue levels of lycopene, including skin and adipose. Differential distribution has been reported among tissue sites.
- Uptake from processed tomatoes greater than fresh tomatoes, in general and when delivered with dietary fat (i.e. dietary oils such as olive oil).
- Disease (vs non-disease) state does not appear to alter uptake (as evidenced by subjects with prostate cancer, breast cancer and kidney disease.
- This does not include malabsorption or GI dysfunction conditions, which may modify uptake.
Summary of studies and outcomes
