Turmeric: Health fad or health fact?

It may not actually be a miracle spice.
What health benefits is turmeric proven to provide?Doctify Nutritionist Dr Claudia Gravaghi says the key ingredient in turmeric is curcumin. It “has powerful antioxidant and anti-inflammatory properties.”In terms of its proven benefits, “research has shown that turmeric extract can help alleviate pain and improve function in people with osteoarthritis”, says Dr Gravaghi. “There is also preliminary evidence that curcumin may help reduce pain in joints and swelling, of people with rheumatoid arthritis, and may reduce inflammation-driven cancer.”Elizabeth Wall, a nutritionist with Holland & Barrett adds that curcumin “helps to neutralise free radicals, which are basically unstable atoms that can cause damage to cells, and contribute to ageing and disease”.
Are there any other research studies going on?Doctify Dermatologist Dr Sweta Rai says the chemical could have positive effects on skin conditions: “High-level, reliable human trials that further investigate tumeric’s use on conditions including acne, atopic eczema, photodamage of photoageing of the skin and alopecia, are currently underway.”Due to its popularity, trials of turmeric and its benefits are on the rise, including trials related to diabetes, Alzheimer’s disease and depression. Wall says this research in its infancy but looking positive.Double-blind, placebo-controlled clinical trials will be required to definitively prove any benefits of curcumin.
What’s the best way to get it into our systems?It’s not that simple.“I don’t think the main focus is on how much turmeric we should be using, more about the form in which we should be using it,” says Wall. This is because curcumin only makes up between 2 and 6% of turmeric.As curcumin exists in such low levels in turmeric, it’s hard to measure how much you are taking when you stir it into a latte or cook it into a curry. There are also issues with the body’s ability to absorb it.“The bright yellow-orange colour of turmeric comes mainly from fat-soluble, polyphenolic pigments known as curcuminoids, says Dr Gravaghi. “When something is fat-soluble, that means it dissolves in fat. Without fat, the active component in turmeric, curcumin, has a difficult time making it past the stomach, into the small intestine, and into the blood where it can offer the greatest benefits.“The best way to take turmeric is with fatty ingredients such as in curry or coconut milk.”Research has also shown that black pepper improves absorption of curcumin into the body.When it comes to your skin, Dr Rai says: “If you’re using turmeric to brighten and enhance your complexion, or reduce photodamage, then applying it to the skin is better.”Wall says that taking the curcumin extract, rather than turmeric in food or drink, may be more beneficial if you are taking it for a therapeutic purpose, because you can track the amount you are taking.
Are there side effects?“Typically, it’s very well tolerated when using it in food, because you’re only using a small amount,” says Wall.However, if you are using excessively large amounts, that could cause issues. The most commonly reported is digestive upset, and other symptoms can include nausea, dizziness and diarrhoea.“There is no known allergy to turmeric per se,” Dr Rai adds. “However, if used on the skin directly in concentrated form, and left on for a long period of time, this may cause contact irritation of the skin.The use of turmeric in treatment of medical conditions should always be discussed with your dermatologist or doctor.

Turmeric, once known as Indian Saffron, has been getting a lot of notice recently. It's used in both Indian and Southeast Asian cooking, but did you also know that it has been used to determine the efficacy of ink-jet printing, or increasing the production of chicken eggs?
