A recently published study out of Portugal found that green tea and hibiscus-based beverages worked the hardest for their consumer, as they had the highest levels of antioxidants out of 19 commercially available drinks.
More than blackberry and raspberry-based products, the combination of green tea and hibiscus proved to be the most antioxidant-rich.
Meanwhile, a study out of Norway catalogued the antioxidant content of more than 3,100 foods, beverages, spices, herbs and supplements in 2010.
Here are some of the most antioxidant-rich foods from the database:
Breakfast cereals, grains, legumes, nuts and seeds
Chestnuts with pellicle, or the skin of the nut
Pecans with pellicle
Walnuts with pellicle
Berries, fruits and vegetables
Baobab, an African fruit
Amla (Indian gooseberry)
Dog rose (dried, fresh)
Dried plums, prunes, apricots, apples
