Dr. Tod Cooperman, from ConsumerLab.com, elaborates on the testing methods and evaluation parameters for various cocoa-based products including dark chocolates, cocoa powders, nibs, and supplements. The aim of these tests is to assess the presence of flavanols, a compound believed to have certain health benefits, and to check for contamination by cadmium, a detrimental heavy metal. Flavanols may help relax blood vessels, slightly decrease blood pressure, mildly improve memory and cognition, and also bring some minor benefits for the skin. However, Dr. Tod, cautions consumers that the percentage of cocoa on product labels does not necessarily reflect the flavanol levels, as flavanols are found in the cocoa liquor and not in the cocoa butter.
Furthermore, the doctor mentions that processing methods such as 'Dutching' can drastically reduce flavanol levels in the product, hence those seeking the health benefits of flavanols should opt for non-Dutched products. Recently tested products exhibited variations in cadmium levels, with some exceeding the safe limit, particularly for children. Hence, he advises restricting cocoa consumption to not more than one cup a day unless you are sure of its cadmium content. The daily requirement for cardiovascular and memory benefits is at least 200-900 milligrams of flavanols which can be challenging to obtain from these products. Cocoa flavanol supplements can be a viable alternative provided they are extracted products. In conclusion, consumers should make informed decisions when choosing cocoa-based products and cocoa flavanol supplements.
