A new study from Japan has revealed that black cumin seed powder could play a significant role in improving cholesterol levels and metabolic health. The research, conducted by scientists in Osaka, involved both laboratory cell tests and a human trial in which participants consumed 5 grams of black cumin seed powder daily for eight weeks. The results showed a marked decrease in bad cholesterol (LDL), triglycerides, and total cholesterol, while simultaneously increasing good cholesterol (HDL). These findings were supported by the study’s dual approach of in-vitro and human trials, which demonstrated black cumin’s potential for improving lipid metabolism and reducing risks associated with obesity-related conditions.
Black cumin, scientifically known as Nigella sativa, is a spice commonly used in Middle Eastern and Indian cuisines, including dishes such as curries and naan. It is also found in various baked goods and spice blends. High-antioxidant black seed oil is often sold as a dietary supplement, with claims of supporting immunity, reducing inflammation, and improving digestive health. The study’s authors noted that the results highlight the potential of black cumin seed extract as a natural agent for managing metabolic and cardiovascular health, though they emphasized that further research is needed to confirm these effects.
Theresa Link, a registered dietitian at Virta Health in Nebraska, provided expert insights on the study’s implications. Cholesterol, she explained, is just one piece of the broader cardiovascular health puzzle. While these findings are promising, Link pointed out that the studies only lasted eight weeks, and black cumin seed alone isn’t a magic bullet for preventing obesity. However, it may support weight management when combined with a healthy lifestyle. She also referenced a 2021 study that found black seed oil led to greater weight loss in women, with participants reporting increased satiety, which likely contributed to their success.
Although the study suggests black cumin’s potential benefits, experts agree that longer-term research is necessary to fully understand its role in metabolic and cardiovascular health. The compound thymoquinone, contained in black cumin, is rich in antioxidants and could offer additional health benefits. The researchers concluded that while the study’s results are encouraging, more comprehensive metabolic parameters and long-term studies are essential to determine the spice’s broader impact on health and wellness.
