NCT01342666

Brief Summary

  • This is a randomized, open-label, single blind, clinical trial
  • The study evaluated the effect of tomato consumption in serum HDL-cholesterol levels.
  • The hypothesis was that two daily tomatoes during one month will increase the HDL-c levels.
  • Since a placebo of tomatoes cannot be done, the control group will receive same proportion of cucumber because 1) it was not possible to have a tomato placebo; 2) cucumber does not have any lycopene; 3) both can be prepared similarly; and 4) the required quantity can be measured in the same way.
  • The intervention was during 1 month and was assigned by randomization.
  • Personnel who did the clinical and biochemical evaluation were blinded for the intervention.
  • Lipid profile was measured before and after the intervention.
  • Confounding factors such as daily physical activity, diet, consumption of fish or alcoholic beverages, smoking status were considered during statistical analyses.
