Conclusion : Cocoa/DC supplementation does not reduce anthropometric measures significantly .
However subgroup analysis regarding dose ( ≥ 30 g/day ) and duration ( between 4 to 8 weeks ) revealed significant reduction of body weight and BMI
ABSTRACT Background : Cocoa and dark chocolate ( DC ) have been reported to be effective for health promotion ; however the exact effect of cocoa/DC on anthropometric measures have not been yet defined .
Regular consumption of cocoa powder with milk increases HDL cholesterol and reduces oxidized LDL levels in subjects at high-risk of cardiovascular disease.
BACKGROUND AND AIMS Epidemiological studies suggest that regular consumption of cocoa-containing products may confer cardiovascular protection , reducing the risk of coronary heart disease ( CHD ) . However , studies on the effects of cocoa on different cardiovascular risk factors are still scarce . The aim of this study was too evaluate the effects of chronic cocoa consumption on lipid profile , oxidized low-density lipoprotein ( oxLDL ) particles and plasma antioxidant vitamin concentrations in high-risk patients . METHODS AND RESULTS Forty-two high-risk volunteers ( 19 men and 23 women , mean age 69.7 ± 11.5 years ) were included in a r and omized , crossover feeding trial . All received 40 g of cocoa powder with 500 mL of skimmed milk/day(C + M ) or only 500 mL/day of skimmed milk ( M ) for 4 weeks in a r and om order . Before and after each intervention period , plasma lipids , oxLDL and antioxidant vitamin concentrations were measured , as well as urinary cocoa polyphenols metabolites derived from phase II and microbial metabolisms . Compared to M , C + M intervention increases HDLc [ 2.67 mg/dL ( 95 % confidence intervals , CI , 0.58 - 4.73 ; P = 0.008 ) ] and decreases oxLDL levels [ -12.3 U/L ( CI,-19.3 to -5.2;P = 0.001 ) ] . No changes between intervention groups were observed in vitamins B1 , B6 , B12 , C and E , or folic acid concentrations . In addition , subjects who showed higher increments in urinary cocoa polyphenol metabolites exhibited significant increases in HDLc and significant decreases in oxLDL levels ( P < 0.05 ; all ) . CONCLUSIONS Consumption of cocoa power with milk modulates the lipid profile  in high-risk subjects for CHD . In addition , the relationship observed between the urinary excretion of cocoa polyphenol metabolites and plasma HDLc and oxLDL levels suggests a beneficial role for cocoa polyphenols in lipid metabolism
