With black pepper to enhance absorption and bioavailability

The Dietary Inflammatory Index names turmeric as the single most anti-inflammatory food.

Numerous studies propose that turmeric can benefit various health conditions.

Over five thousand articles about curcumin, the pigment in turmeric that gives curry powder its golden color, have been published in the medical literature. Curcumin was first isolated over a century ago. Despite thousands of experiments, only a few clinical studies involving human participants were conducted in the twentieth century. However, since the turn of the century, curcumin has been tested against a variety of diseases in more than 50 clinical trials, with dozens more underway.

The National Cancer Institute has tested over a thousand compounds for cancer-preventing activity since 1987. Only a few dozen have reached clinical trials, and curcumin, turmeric’s bright-yellow pigment, is among the most promising. Cancer-preventing agents can be classified into different subgroups based on the stage of cancer development they combat: Carcinogen blockers and antioxidants help prevent the initial triggering DNA mutation, while antiproliferatives prevent tumors from growing and spreading. Curcumin is unique as it belongs to all three groups, potentially helping to prevent and/or halt cancer cell growth.

Black pepper contains a bioactive compound called piperine, which enhances the absorption and bioavailability of curcumin (the main active compound in turmeric) in the body.

What are the longevity benefits of taking turmeric?

The longevity benefits of taking turmeric, primarily due to its active compound curcumin, are supported by various studies and research findings. Here are the key points:

Lifespan Extension

1. Model Organisms: Curcumin has been shown to extend the lifespan of several model organisms, including fruit flies (Drosophila melanogaster), nematodes, and mice. For instance, a study demonstrated that fruit flies maintained on media supplemented with curcumin had a significant increase in mean lifespan[5]. Similar results were observed in nematodes and mice, indicating a broad potential for lifespan extension across different species[1].

Anti-Aging Properties

1. Cellular Senescence: Curcumin has been found to alleviate symptoms of aging and postpone the progression of age-related diseases by modulating cellular senescence. It protects cells from oxidative stress and increases the levels of proteins like sirtuins and AMPK, which are involved in the aging process[1][4].
2. Neuroprotective Effects: Curcumin serves as a neuroprotective agent, reducing symptoms of age-related diseases such as atherosclerosis, diabetes, and cancer. It also protects against chemotherapy-induced side effects and radiation-induced dermatitis in cancer patients[1].

Healthspan Improvement

1. Inflammation and Oxidative Stress: Curcumin's anti-inflammatory and antioxidant properties play a crucial role in mitigating symptoms of aging. It reduces systemic and immune inflammation, which is a common characteristic of aging[2][3].
2. Metabolic Health: Curcumin has been shown to lower blood sugar levels and improve metabolic health, which can contribute to increased longevity. It also has additive effects with oral antidiabetic drugs, enhancing their efficacy[3].

Real-World Observations

1. Curry Consumption: A prospective cohort study involving 4551 adults aged 55+ found that moderate curry consumption, which is rich in curcumin, was associated with increased life expectancy. Among participants without cardio-metabolic and vascular diseases (CMVD), life expectancy increased by 1.9 years. Even among those with CMVD, occasional curry consumption was associated with a decreased mortality risk and an increased life expectancy by 1.0 year[2].

Mechanisms of Action

1. Molecular Pathways: Curcumin influences several molecular pathways associated with aging. It inhibits pro-aging proteins such as NF-κB and mTOR while enhancing the activity of proteins that promote longevity, such as sirtuins and AMPK[4].

Conclusion

Overall, the consumption of turmeric, particularly its active compound curcumin, offers significant longevity benefits. These benefits are attributed to its ability to extend lifespan, alleviate aging symptoms, improve metabolic health, and reduce inflammation and oxidative stress. The positive impact of curcumin on aging and healthspan is supported by both experimental studies and real-world observational data.
