Food products with significant antioxidant properties, such as green tea (79), degrade in antioxidant activity over time. Delva P. Magnesium and coronary heart disease. Endothelial function refers to arterial vasomotor responses mediated predominantly by the release of NO (vasodilating), and endothelin (vasoconstricting) from the vascular endothelium (145, 266), and plays an important role in the pathogenesis of atherosclerosis, hypertension, and cardiovascular disease (266). Procyanidins and catechins may prevent inflammatory and oxidative damage to DNA and thus affect carcinogenesis. Hamed F. Tantry US. FOIA On the other hand, there is some evidence to support a psychoactive effect of flavanols or methylxanthine compounds in cocoaeffects that may extend beyond mood to cognitive function. In their second study, Grassi and colleagues used the same research design and chocolate dose to test the effects of regular dark chocolate consumption in 19 hypertensive subjects who were also glucose intolerant (84). However, potential in this area will not be fully realized until or unless parameters for prescription are established. Thus, the availability of NO likely plays a role in mediating cells' response to insulin. Flavonoid intake and long-term risk of coronary heart disease and cancer in the seven countries study.

Evolving concepts in the triad of atherosclerosis, inflammation and thrombosis. Boelsma E. van de Vijver LP. This effect may be directas in the case of calcium channel blockers, statins, ACE inhibitors, and AT-1 receptor antagonistsor indirectas in acarbose and glinides, which prevent oxidative stress caused by postprandial hyperglycemia (35). In contrast to the positive findings of studies in healthy individuals and those with cardiovascular risk factors, the results of a study in 40 subjects with CAD were null (67). Ramiro-Puig E.

As noted (see pp. Nitric oxide and other endothelium-derived factors are important for the control of vascular biology, not only in the peripheral but also in the cerebral circulation (81). And since cocoa is a mix of healthy monounsaturated fats (like oleic acid, the same fat in olive oil) and saturated fats (like coconut oil), all these fatty acids may also lead to better cardiovascular health[*]. Insights generated might have implications for fortification and functional foods, and help food scientists answer the questions most germane to their efforts: what additions, deletions, and/or modifications enhance or attenuate favorable health effects of chocolate? Ideally, your unsweetened cacao powder should just contain pure, untreated, ground cacao beans. (113) assessed commercial preparations of chocolate and found that milk chocolate bars maintain oxygen radical absorbance capacity (ORAC), total polyphenols, and flavan-3-ol monomers for at least 50 weeks in commercial preparations, whereas cocoa powder and cocoa beans demonstrate stability in samples over 75 years old. Other study populations included diabetic patients (17); hypertensives (85); hypertensives with impaired glucose tolerance (84); patients with at least one cardiovascular risk factor (92); and heart transplant recipients (75). Cocoa powder is rich in theobromine, which helps to reduce inflammation and can protect you from diseases such as heart disease, cancer, and diabetes. In this study, HDL levels increased 6.6% in the high flavanol group, whereas HDL decreased 9.6% in the low flavanol group (p<0.05). Cooke JP. However, Berry and colleagues demonstrated that consumption of a high-flavanol (701mg) cocoa beverage could significantly improve BP response to exercise compared to a low-flavanol (22mg) beverage (21). Weisburger JH. Wang JF. For example, ingestion of cocoa containing 36mg of flavanols did not significantly change FMD, whereas cocoa containing 330mg increased FMD at 1, 2, and 3h after ingestion and cocoa containing 918mg increased FMD at 1, 2, 3, 4, and 6h after ingestion.

Surh YJ. Which of these effects predominates, and which has the most direct clinical significance is unknown. However, radical-scavenging Maillard reaction products such as melanoidins are also produced during roasting, partially replacing the lost antioxidant activity of cocoa polyphenols (191). This suggested that cocoa may be an effective natural treatment for hypertension[, Scientists in another study compared the effect of flavonoid-rich dark chocolate intake against a cocoa-free diet. Williams MJ. Chronopoulos AK. In addition to a reduction in risk for MI and stroke, Buijsse et al.

In the second acute study, a separate group of six subjects received cocoa with 28, 179, and 483mg of flavanols. Engler MM. The translation of this general theme in the literature into specific public health guidance would seem the next great challenge for the research community. The differential effects of chocolate observed in those with and without established coronary disease is an area clearly warranting further examination. Manach C. Scalbert A. Morand C. Remesy C. Jimenez L. Polyphenols: food sources and bioavailability. Strandberg TE. Walker RJ. These findings suggest that although cocoa's effects on the vascular endothelium occur primarily in the short-term, chronic consumption may result in sustained benefits. In the treatment group (squares), FMD was significantly augmented over time. They were then given the opportunity to complete a computer task to earn reinforcers of chocolate or carob.
Corti R. Flammer AJ. If artificially sweetened cocoa is determined to have greater benefit than cocoa with sugar, palatability of such products will be an important consideration. McCormick MP. Cooper KA. Leone N. Courbon D. Ducimetiere P. Zureik M. Zinc, copper, and magnesium and risks for all-cause, cancer, and cardiovascular mortality. The cocoa capsules had only a minimal decrease (16 points), which was similar to the reductions observed after consumption of flour capsules and no treatment. Hamasaki S. Higano ST. Nishimura RA. The Polymeal: a more natural, safer, and probably tastier (than the Polypill) strategy to reduce cardiovascular disease by more than 75%. (41). FMD and BP were measured after an 8-h fast and 2h after ingestion of each treatment. The antioxidant actions of cocoa flavanols are one possible mechanism by which skin protection could be conferred. What is known is that chocolate, unlike spinach, carries with it the liabilities of processing, added ingredients (notably sugar), and energy density. After adjustment for demographic and socioeconomic variables, coffee consumption, and intake of sweets, there was a significant, linear, inverse relationship between frequency of chocolate consumption and cardiac mortality (p=0.01). Sorond FA. Consumption of cocoa flavanols results in acute improvements in mood and cognitive performance during sustained mental effort. Flammer AJ. [May 10;2010 ].

Flavanol-rich cocoa: a cardioprotective nutraceutical. 8600 Rockville Pike They permit, however, comparison of structurally related compounds. Endothelial NO is produced by endothelial nitric oxide synthase (eNOS), which converts L-arginine to L-citrulline in the presence of necessary cofactors (143). Although the specific mechanisms responsible for this association have not yet been identified, it has been theorized that flavanols may affect the activity of platelets by inducing changes in membrane fluidity, ligand-receptor affinity, and intracellular signaling pathways (105). This hypothesis is supported by the observation that many antidiabetic drugs and drugs used to treat cardiovascular disease demonstrate antioxidant effects. In one study, daily cocoa (900mg flavanols) ingestion for 2 weeks was not sufficient to improve measures of insulin resistance, though it did improve insulin-mediated vasodilation (178). As suggested by Table 6, diverse constituents of chocolate are known to exert a wide array of metabolic effects of potential clinical importance. McHale NL. Plasma antioxidants from chocolate.

Absorption and urinary excretion of procyanidin B2 [epicatechin-(4beta-8)-epicatechin] in rats. Bae JH. Little actual evidence of that harm exists, however, at least for dark chocolate per se. Urpi-Sarda and colleagues found that urinary excretion of vanillic acid and phenylacetic acid increased after milk and cocoa were consumed together, whereas urinary excretion of other components (3,4-dihydroxyphenylacetic acid, protocatechuic acid, 4-hydroxybenzoic acid, 4-hydroxyhippuric acid, and hippuric acid) was reduced (263). The role of mitochondria in apoptosis. looked to cocoa's methylxanthine compounds, caffeine and theobromine, as potential mood-altering agents (236) in two studies. Endothelium-derived NO regulates vasodilation and the environment of the blood vessel wall (228), and is therefore critical for vascular function. Best Premium Choice: Divine Cocoa Powder.

Metabolic effects of dark chocolate consumption on energy, gut microbiota, and stress-related metabolism in free-living subjects. Our lab has conducted two studies to investigate the effects of cocoa or chocolate on endothelial function. Although molecular, metabolic, and overall medical effects of chocolate may owe something more to the whole than to any given part, food science would, nonetheless, benefit from further study of specific parts, or compounds, both in isolation and in various combination. Michener W. Rozin P. Pharmacological versus sensory factors in the satiation of chocolate craving. Fraga CG. Angeli FS. The composition of test products used in this study is provided in Table 4.

In a 2007 study series, Heiss et al. Luscher TF. Shukitt-Hale B. Denisova NA. Ceriello and Motz have proposed that oxidative stress is the underlying mechanism for both insulin resistance and cardiovascular disease (35). Mitchell JA. Flavanols, particularly epicatechin (222), in cocoa have anti-inflammatory properties that inhibit the production of ROS, and have antihypertensive and vasoprotective effects (42). Kenny TP.
