A bioavailability study however refutes this, showing that there was no difference in the acute increases in plasma or urinary concentrations of flavanols after consumption of chocolate or dry cocoa containing the same quantities of flavanols (Baba et al., 2000).
Group 1 received a 50 g daily dose of dark chocolate with 70% cocoa containing 750 mg polyphenols, group 2 were allocated one tomato extract capsule containing 15 mg lycopene per day, and group 3 received one placebo capsule daily over 8 weeks followed by a 4-week washout period.
So only raw cocoa and, to a lesser extent, dark chocolate, offer these benefits.Second, cocoa contains a stimulant called theobromine which has some positive health effects.
Agatston says cocoa contains flavanols, which may help maintain a healthy cardiovascular system by relaxing blood vessels and keeping cholesterol from building up in them thus reducing the risk of blood clots and by slowing down the immune responses that lead to clogged arteries.
A 2003 study from Cornell University found that cocoa contains large amounts of antioxidants that may help prevent cancer.
In fact, cocoa contains double the flavon-3-ol anti-oxidant content of red wine, and five times that of green tea.
In fact, 100 grams of cocoa contains a whopping 13,120 oxygen radical absorbance capacity (ORAC), the measure of antioxidant capacity! Antioxidants have the potential to improve overall health, delay the onset of many age-related diseases, reduce the risk of some cancers, improve cardiovascular function, and more.
In summary, chocolate products and manufactured cocoa contain relatively high levels of contaminant lead compared with the baseline value for Nigerian cocoa beans used to make those products.
M. perniciosa, the causal agent of the witches' broom disease of cocoa, contains only two cutinases (CE5), which is fewer than any other hemibiotrophic fungi.
A number of scientific studies have found that extra dark chocolate, containing 80percentt cocoa solids or more, is uniquely high in potent, heart-healthy flavon-3-ol antioxidants.
This solid chocolate contains cocoa powder, cocoa butter, and usually but not al-ways sugar.
