ISLAMABAD-First study to use objective measure to look at 25,000 people’s diet. People who consume a diet including flavanol-rich foods and drinks, including tea, apples, and berries, could lead to lower blood pressure, according to the first study using objective measures of thousands of UK residents’ diet. The findings, published in Scientific Reports, studied the diet of more than 25,000 people in Norfolk, UK and compared what they ate with their blood pressure. In contrast to most other studies investigating links between nutrition and health, the researchers did not rely on study participants reporting their diet, but instead measured flavanol intake objectively using nutritional biomarkers — indicators of dietary intake, metabolism or nutritional status that are present in our blood. The difference in blood pressure between those with the lowest 10% of flavanol intake and those with the highest 10% of intake was between 2 and 4 mmHg. This is comparable to meaningful changes in blood pressure observed in those following a Mediterranean diet or Dietary Approaches to Stop Hypertension (DASH) diet. Notably, the effect was more pronounced in participants with hypertension.
