Turmeric Study (04:07)
Cancer rates are low in countries where people cook with turmeric. Volunteers will consume turmeric powder, take a supplement, or take a placebo for six weeks. An oxidative stress test will measure their immune response and a ground-breaking test will measure cancer precursors.
Glucosamine Test (03:37)
Dr. Chris van Tulleken discusses using unregulated glucosamine supplements for joint pain. His team analyzes the chemistry of nine brands; two have 30% less glucosamine than the others. There is no scientific consensus that it reduces arthritis.
Arthritis Study (05:25)
Osteoarthritis expert Dr. Phil Conahan runs an experiment with volunteers doing knee exercises or taking a placebo glucosamine supplement. After eight weeks, 80% of the exercise group and 55% of the supplement group have reduced pain.

Caroline has a higher risk of breast and ovarian cancer; she had a bilateral mastectomy and her ovaries removed. Dr. Gabriel Weston explains DNA methylation. Epigenetics researchers discovered it can go wrong, leading to cancer.
Cancer Early Warning System (04:18)
Dr. Martin Widschwendter identified a DNA methylation signature predicting breast cancer; changes are reversible. He is developing a test looking for aberrant patterns in several cancer types. Turmeric may reduce cancer risk, as well as smoking and alcohol cessation.
