Siim Land provides a list of foods with the highest polyphenol content per 100g, placing cloves at the top of the list.

The classification presented relies heavily on data from the Phenol-Explorer database, which is a reference in phenolic compound research. It is accurate that spices like cloves and star anise possess an exceptionally high density of polyphenols compared to typical fruits or vegetables, as confirmed by phytochemical characterization studies (source: meta-analysis and nutritional databases). However, it is important to note that we consume these foods in very different quantities: a few grams of cloves versus larger servings of berries or nuts. While the content per 100g is technically correct, the real impact on health depends on the bioavailability of these compounds and the amount actually ingested daily. The claim is therefore factual from an analytical perspective, but it may lead to a misleading interpretation of these foods' actual contribution to the total antioxidant intake in a standard diet. Research emphasizes that the diversity of sources remains more decisive than simple concentration per 100g.
