Turmeric curcumin, an orange-colored spice imported from India, is part the ginger family and has been a staple in Middle Eastern and Southeast Asian cooking for thousands of years.
In addition, ayurvedic and Chinese medicines utilize turmeric to clear infections and inflammations on the inside and outside of the body. But beyond the holistic health community, Western medical practitioners have only recently come on board in recognizing the health benefits of turmeric.
Here 10 ways turmeric curcumin may benefit your body
Doctors at UCLA found that curcumin, the main component in turmeric, appeared to block an enzyme that promotes the growth of head and neck cancer.
In that study, 21 subjects with head and neck cancers chewed two tablets containing 1,000 milligrams of curcumin. An independent lab in Maryland evaluated the results and found that the cancer-promoting enzymes in the patients’ mouths were inhibited by the curcumin and thus prevented from advancing the spread of the malignant cells.
The University of Maryland’s Medical Center also states that turmeric’s powerful antioxidant properties fight cancer-causing free radicals, reducing or preventing some of the damage they can cause.
While more research is necessary, early studies have indicated that curcumin may help prevent or treat several types of cancer including prostate, skin and colon.
Dr. Randy J. Horwitz, the medical director of the Arizona Center for Integrative Medicine and an assistant professor of clinical medicine at the University of Arizona College of Medicine in Tucson, wrote a paper for the American Academy of Pain Management in which he discussed the health benefits of turmeric.
“Turmeric is one of the most potent natural anti-inflammatories available,” Horwitz states in the paper.
He went on to cite a 2006 University of Arizona study that examined the effect of turmeric on rats with injected rheumatoid arthritis. According to Horwitz, pretreatment with turmeric completely inhibited the onset of rheumatoid arthritis in the rats. In addition, the study found that using turmeric for pre-existing rheumatoid arthritis resulted in a significant reduction of symptoms.
Some research shows that curcumin might ease symptoms of uveitis — long-term inflammation in the middle layer of the eye. Other research shows that taking turmeric daily for several months may improve kidney function for people with kidney inflammation.
Turmeric may also be helpful with another type of arthritis. Some research has shown that taking turmeric extract can ease the pain of osteoarthritis. In one study, reports WebMD, turmeric worked about as well as ibuprofen for relieving osteoarthritis pain.
and heartburn aid
Curcumin works with the gallbladder, stimulating it to make bile, which may help with digestion. In Germany, turmeric can be prescribed for digestive problems. Some research shows that turmeric may help upset stomach, bloating and gas. Turmeric may also help reduce the occurrence of irritable bowel syndrome (IBS) in people who are otherwise healthy.
Studies have suggested curcumin may help prevent the buildup of plaque that can clog arteries and lead to heart attacks and strokes.
Impact on diabetes
Early studies suggest that taking turmeric daily can cut down the number of people with prediabetes who develop diabetes.
“Raw is best”
Natalie Kling, a Los Angeles-based nutritionist, says she first learned about the benefits of turmeric while getting her degree from the Natural Healing Institute of Neuropathy. “As an anti-inflammatory, antioxidant and antiseptic, it’s a very powerful plant,” she says.
Kling recommends it to clients for joint pain and says that when taken as a supplement, it helps quickly. She advises adding turmeric to food whenever possible and offers these easy tips. “Raw is best,” she said. “Sprinkling it on vegetables or mixing it into dressings is quick and effective.”
If you do cook it, make sure to use a small amount of healthy fat like healthy coconut oil to maximize flavor. Kling also recommends rubbing turmeric on meat and putting it into curries and soups.
“It’s inexpensive, mild in taste, and benefits every system in the body,” Kling says. “Adding this powerful plant to your diet is one of the best things you can do for long term health.”
An Effective Treatment for Inflammatory Bowel Disease
Curcumin may provide an inexpensive, well-tolerated, and effective treatment for inflammatory bowel disease (IBD) such as Crohn’s and ulcerative colitis, recent research suggests. In this study, mice given an inflammatory agent that normally induces colitis were protected when curcumin was added to their diet five days beforehand. The mice receiving curcumin not only lost much less weight than the control animals, but when researchers checked their intestinal cell function, all the signs typical of colitis (mucosal ulceration, thickening of the intestinal wall, and the infiltration of inflammatory cells)were all much reduced. While the researchers are not yet sure exactly how curcumin achieves its protective effects, they think its benefits are the result of not only antioxidant activity, but also inhibition of a major cellular inflammatory agent called NF kappa-B. Plus, an important part of the good news reported in this study is the fact that although curcumin has been found to be safe at very large doses, this component of turmeric was effective at a concentration as low as 0.25 per cent—an amount easily supplied by simply enjoying turmeric in flavorful curries.
Relief for Rheumatoid Arthritis
Clinical studies have substantiated that curcumin also exerts very powerful antioxidant effects. As an antioxidant, curcumin is able to neutralize free radicals, chemicals that can travel through the body and cause great amounts of damage to healthy cells and cell membranes. This is important in many diseases, such as arthritis, where free radicals are responsible for the painful joint inflammation and eventual damage to the joints. Turmeric’s combination of antioxidant and anti-inflammatory effects explains why many people with joint disease find relief when they use the spice regularly. In a recent study of patients with rheumatoid arthritis, curcumin was compared to phenylbutazone and produced comparable improvements in shortened duration of morning stiffness, lengthened walking time, and reduced joint swelling.
Help for Cystic Fibrosis Sufferers
Curcumin, the major constituent of turmeric that gives the spice its yellow color, can correct the most common expression of the genetic defect that is responsible for cystic fibrosis, suggests an animal study published in the Science (April 2004). Cystic fibrosis, a fatal disease that attacks the lungs with a thick mucus, causing life-threatening infections, afflicts about 30,000 American children and young adults, who rarely survive beyond 30 years of age. The mucus also damages the pancreas, thus interfering with the body’s ability to digest and absorb nutrients.
Researchers now know that cystic fibrosis is caused by mutations in the gene that encodes for a protein (the transmembrane conductance regulator or CFTR). The CTFR protein is responsible for traveling to the cell’s surface and creating channels through which chloride ions can leave the cell. When the protein is abnormally shaped because of a faulty gene, this cannot happen, so chloride builds up in the cells, which in turn, leads to mucus production.
The most common mutation, which is called DeltaF508, results in the production of a misfolded protein. When mice with this DeltaF508 defect were given curcumin in doses that, on a weight-per-weight basis, would be well-tolerated by humans, curcumin corrected this defect, resulting in a DeltaF508 protein with normal appearance and function. In addition, the Yale scientists studying curcumin have shown that it can inhibit the release of calcium, thus allowing mutated CTFR to exit cells via the calcium channels, which also helps stop the chloride-driven build up of mucus. Specialists in the treatment of cystic fibrosis caution, however, that patients should not self-medicate with dietary supplements containing curcumin, until the correct doses are known and any adverse interactions identified with the numerous prescription drugs taken by cystic fibrosis sufferers.
