Diallyl disulfide potentiates anti-obesity effect of green tea in high-fat/high-sucrose diet-induced obesity

Summary

This 2018 laboratory study investigated the synergistic potential of diallyl disulfide (a bioactive sulphur compound from garlic) combined with green tea catechins in mitigating obesity and metabolic dysfunction induced by a high-fat/high-sucrose diet. The authors report that co-administration of these plant-derived bioactives produced greater reductions in weight gain and adiposity than either compound alone, suggesting a mechanistic interaction between the two food constituents. The findings indicate potential therapeutic value in combining functional food components, though translation to human dietary contexts requires further investigation.

UK applicability

Whilst the study employs a laboratory animal model and addresses mechanisms potentially applicable across populations, direct applicability to UK public health policy or dietary guidance remains limited without human clinical trials. The findings may inform future research into functional foods and nutraceutical combinations for obesity prevention in UK populations, but cannot currently guide clinical recommendations.

Key measures

Body weight gain, adipose tissue mass, plasma lipids, glucose metabolism, hepatic steatosis markers, catechin and diallyl disulfide bioavailability

Outcomes reported

The study measured body weight gain, adiposity (fat accumulation), and metabolic markers in diet-induced obesity models treated with diallyl disulfide, green tea catechins, or their combination. The authors assessed whether the garlic-derived compound potentiates the anti-obesity efficacy of green tea under high-fat/high-sucrose feeding conditions.
