Culinary herbs and spices significantly contribute to dietary polyphenol intake. This study found that common herbs and spices provide meaningful amounts of beneficial polyphenols, often overlooked in dietary assessments.
Area of Science:
- Nutritional Science
- Food Chemistry
- Dietary Assessment
Background:
- Culinary herbs and spices are rich sources of bioactive polyphenols.
- Previous studies have not fully quantified polyphenol intake from herbs and spices.
- The exact contribution of herbs and spices to overall polyphenol consumption remains unclear.
Purpose of the Study:
- To measure the total polyphenol consumption from culinary herbs and spices in adults.
- To determine the contribution of herbs and spices to dietary polyphenol intake.
- To assess potential underestimation of polyphenol intake in existing dietary reports.
Main Methods:
- A validated online herb and spice questionnaire was used.
- Consumption frequency and amount of 27 herbs and spices were recorded over the past month.
- Total polyphenol content was calculated using the Phenol-Explorer database.
Main Results:
- Adults consumed a median of 679.92 mg of total polyphenols from 47.44 g of herbs and spices monthly.
- Cinnamon, black pepper, and cloves were the primary sources of polyphenols.
- Individual polyphenol intake from herbs and spices was quantified.
Conclusions:
- Herbs and spices provide substantial amounts of dietary polyphenols.
- Current dietary assessments may underestimate total polyphenol intake by 3-12% due to unquantified herb and spice contributions.
- Incorporating herb and spice data is crucial for accurate dietary polyphenol evaluations.
