The compound resveratrol was not tied to less cardiovascular disease, inflammation, cancer or with the increased longevity amongst a group of Italians who were elderly, said researchers.
Past studies found that the compound, resveratrol, which is present naturally in certain vegetables and fruits, has properties that might benefit the health of individuals, wrote researchers,
However, little evidence was shown on the effect of the compound on a larger group, they added.
In 2012, resveratrol research ran into a snag when once of the leading researchers in the field was accused of making up data.
For this new study, researchers used data taken from over 780 Italians who had been tracked since 1998, when they had been 65 years of age.
The participants were given an examination by doctors and asked to fill out a questionnaire pertaining to their diets.
The Italians also gave urine samples to measure the level of resveratrol that was broken down.
A little over 33% of the participants died over the following nine years. Nearly 5% received a cancer diagnosis and 27% of those without heart disease initially, developed the disease over the course of the study.
Researchers also found no difference in the rates of heart disease, cancer or deaths or in the quantity of inflammation between people who began with low amounts of resveratrol that was broken down in their urine.
Although the levels of resveratrol were just measured once, researchers said diet had been assessed in three-year increments through questionnaires and did not change that much through the study, so the researchers assumed the resveratrol in the participant’s urine stayed consistent.
One researcher who did not participate in the study said she was not all that surprised by the study’s findings.
The researcher said she would not expect the resveratrol found in the normal diet to have any effect that is detectable on the individual’s health.
The researcher however did say there might be some health effects that are detectable, from doses that are much larger of resveratrol, but that is still not certain.
