Do antioxidants lower high blood pressure? – results of a new clinical study in France

There has been evidence to suggest that fruit and vegetable consumption can lower high blood pressure, also known as hypertension. 

One way to increase the total antioxidant capacity (TAC) is by increasing fruits and vegetables or even supplementation as shown in short-term clinical trials.

A recent study was performed in France to determine if antioxidant can decrease hypertension (i.e. high blood pressure.

Here are the study details

Human subjects: 74,520 participants responded to a follow-up questionnaire that included a validated self-administered diet history questionnaire

Method: Antioxidant supplement intake was assessed through the 1995, 2000, 2002, and 2005 questionnaires.

Participants were asked about their intakes of different vitamins and minerals, including vitamin E, vitamin C, and beta-carotene if consumed at least three times per week.

Here are the main results

Increasing total antioxidant capacity was associated with decreased blood pressure (i.e. decreased hypertension).

Here is what the authors had to say

To the best of our knowledge, this is the first time that an inverse association between the dietary total antioxidant capacity and the risk of hypertension has been shown. 

And

In our analyses considering the antioxidant capacity of specific food groups, dietary TAC of fruit and vegetables, of wine, and of other miscellaneous foods were inversely associated with hypertension.

And

Our findings showed that a high TAC diet was associated with a reduced risk of incident hypertension in women, suggesting that promoting a diet naturally rich in antioxidants might help prevent the development of hypertension. These results have to be interpreted cautiously
