Insights & Discussion
Chocolate and cocoa product consumption significantly improved lipid profiles, but had no significant effect on other heath aspects such as cognitive function and blood pressure.
A systematic search was performed on academic databases such as MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials. The researchers utilized a precise search strategy and keywords to gather the most relevant studies and evidence. The studies focused on a variety of health effects related to the consumption of chocolate and cocoa products, like their effects on skin, cardiovascular health, anthropometry, cognitive function, blood glucose levels, and overall quality of life.
The research revealed considerable improvements in lipid profiles (particularly in triglycerides) among those who consumed chocolate or cocoa products, compared to controls. However, there were no significant differences observed in other outcome parameters related to skin health, blood pressure, cognitive function, anthropometry, blood glucose levels, and quality of life between the chocolate/cocoa consumption group and the control group. The subjects generally accepted chocolate well, with gastrointestinal disturbances and unpalatability reported as their main concerns.

Randomised Controlled Trial Cocoa
In a randomized, double-blind, placebo-controlled study involving 120 male volunteers aged between 21 and 35 years, participants were arranged into three groups. Each group received a daily dose of either a placebo or 200 or 400 mg of LN18178 for a duration of 56 days. The primary focus of the study was to measure the potential increase in serum testosterone levels (both free and total). Secondary measures incorporated other hormones like dihydrotestosterone, cortisol, and Luteinizing hormone, as well as physical indicators such as hand grip strength and mid-upper arm circumference. Additionally, thorough checks were run pertaining to each participant's vital signs and clinical chemistry parameters in blood and urine to ensure product safety.
After the intervention, both dosage levels of LN18178 significantly raised free testosterone levels. The higher dose group also showed noteworthy increases in total testosterone and luteinizing hormone levels. Meanwhile, the other hormone changes were found to be statistically insignificant. More importantly, the LN18178-400 group displayed significant enhancements in their hand grip strength and mid-upper arm circumference post-trial. The completion of the trial saw participants' vital signs and hemato-biochemical parameters within the normal range, suggesting that LN18178 is both safe and tolerable.
Cocoa extract supplementation in older adults reduced cardiovascular disease related death rates, but did not significantly lessen total cardiovascular events.

Randomised Controlled Trial Cardiovascular Disease Cocoa
A randomized, double-blind, placebo-controlled trial was conducted on 21,442 US adults aged 60 or over, all of who were free of major cardiovascular disease and recently diagnosed cancer. The participants were assigned to either a cocoa extract supplement, which included 500 mg flavanols per day, or a placebo. The intervention phase ran from June 2015 to December 2020. The primary outcome was focused on the number of total cardiovascular events, including myocardial infarction, stroke, and cardiovascular death among others.
The results showed that during a median follow-up of 3.6 years, there were 410 participants taking cocoa extract and 456 under placebo who had confirmed total cardiovascular events. Secondary endpoints showed reduced death due to cardiovascular disease for the cocoa extract supplement users. However, there was no significant impact on the incidence of total cardiovascular events. Conversely, a lower risk of total cardiovascular events was supported when analyses were censored at nonadherence. Overall, no safety concerns were raised during the trial.

Clinical Study Cancer Cancer Treatment Support Chocolate
In the conducted study, 46 older cancer patients under palliative care were divided into three groups. The control group did not have a change in their diet (CG, 15 patients). The other two groups were given intervention foods—55% cocoa chocolate (IG1, 16 patients) and white chocolate (IG2, 15 patients)—for a duration of four weeks. The primary outcome was assessed based on changes in the patients' nutritional status, as measured by the Mini Nutritional Assessment tool. Other factors examined included food consumption, body measurements, body composition, laboratory parameters, and quality of life, using the European Organization for the Research and Treatment of Cancer instrument.
Discussion of the results revealed that the group consuming 55% cocoa chocolate showed an improvement in nutritional scores and functionality, as evidenced by the Mini Nutritional Assessment and the quality of life scores respectively. On the other hand, the group consuming white chocolate displayed decreased oxidative stress levels. However, body composition and anthropometric measurements remained largely unchanged across all three groups.

Systematic Review Blood Sugar Cocoa Dark Chocolate
A systematic search of databases identified eight randomized controlled trials (RCTs) with 433 participants for meta-analysis. The results demonstrated a substantial reduction in LDL-c levels (WMD: −15.49 mg/dl) and FBS concentrations (WMD: −6.88 mg/dl) following cocoa/dark chocolate consumption. The study emphasizes the potential positive effects of cocoa/dark chocolate on the metabolic profile of diabetic individuals.
The meta-analysis included RCTs focusing on cocoa/dark chocolate interventions in diabetic patients, with a significant pooled analysis showing reduced LDL-c and FBS levels. The findings suggest that incorporating cocoa/dark chocolate in the diet of diabetic individuals could be beneficial for managing lipid profile and glycemia. Further research is necessary to solidify these insights and understand the complete impact on metabolic health.

Systematic Review Anxiety Cocoa
The study carried out a systematic review and meta-analysis in line with PRISMA guidelines to ascertain the effects of cocoa-derived food on depressive and anxiety symptoms, as well as positive and negative affect. Potential sources were found on Web of Knowledge and PsycINFO until April 3, 2020. Out of 761 documents screened, nine studies were picked. Two trials were involved in examining the long-term impact (>1 week) of cocoa consumption, two reviewed the short-term effects (3 days), and five studies were conducted in acute conditions (single administration).
The results indicate that cocoa-rich products had a significant overall effect on reducing depressive and anxiety symptoms. There was also significant improvement in both positive and negative affect. The effect size in all meta-analyses was medium, while the heterogeneity was low. Despite these promising outcomes, the conclusions must be cautiously interpreted due to the short duration of the trials and the limited number of participants and studies included in the meta-analyses.
