In this master's thesis we obtained and elaborated data on the content of anti-oxidants determined by the Folin Ciocalteu assay for 24 different types of fresh fruit and 20 types of vegetables. For each species we obtained data from at least ten different scientific publications. Obtained data were statistically analyzed and average and median value of the antioxidant content were determined. The analysis of the results revealed great differences between publications for the same types of fruits or vegetables. The median of the quotients between the highest and the lowest antioxidant content for the particular species is 22 for fruits and 18 for vegetables. We also obtained data on average retail prices for 23 types of fruit and 17 types of vegetables in years 2014 and 2015, for the USA. We have found that there are differences in the price accessibility of fruit and vegetables that are perceived as healthier, but also price differences, depending on the size of the packaging and the type of agricultural practice (organic, conventional). Normalizing the content of antioxidants to the price reveals that the fruit, such as plums, bananas and apples and vegetables like potatoes, onion and cabbage are the most affordable source of antioxidants.
