- Abstract
The intake of extractable antioxidants in the Czech Republic was studied using the FRAP (ferric reducing antioxidant potential) method applied to water-methanol extracts. The daily intake of these antioxidants was 16.6 mmol generated Fe(II) for men and 15.0 mmol for women (i.e. 8300 and 7500 µmol Trolox equivalents). The largest sources of antioxidants were coffee (43.1% of overall intake for men and 54.6% for women) and beer (15% for men vs. 1.8% for women). Other significant sources of antioxidants were tea, vegetables and vegetable products (including potatoes and potato products), fruit and fruit products, cereal products, wine, sugars and sweets, spices and meat and meat products. Small amounts of antioxidants (less than 1.0% of overall intake) were supplied by nuts and seeds, milk and milk products and fats, while pulses, eggs and egg products, convenience foods and cheese were insignificant sources of antioxidants. Within the fruit and fruit products category, apples were the most significant source of extractable antioxidants, and in the vegetable and vegetable products category, peppers were the largest source of antioxidants.
