Turmeric has long been valued for its health-promoting properties, which are now backed by scientific evidence.
The stems of turmeric are often dried and made into teas and extracts or powdered into capsules, tablets, and paste. (1)
When used in cooking, it is best to combine turmeric with some sort of fat, such as oil, butter, nuts, or avocado, and peppercorns, to improve its absorption in the body.
This spice also helps prevent the loss of beta-carotene from other vegetables such as carrots and pumpkin during the cooking process. (2)
Nutritional Value of Turmeric
One tablespoon of ground turmeric powder contains 29 calories, 6 grams of carbohydrate, 2 grams of fiber, 1 gram of fat, and little protein. It contains about 16% of your daily iron needs (2.8 mg) and 26% of your daily manganese needs (0.5 mg). (3)
It also contains vitamins B3, C, E, and K. Other components of turmeric include minerals such as calcium, copper, iron, magnesium, potassium, and zinc.
Health Benefits of Turmeric
Turmeric may help improve your health in the following ways.
1. Wound healing
Turmeric was also found useful in speeding up skin healing after a Caesarean section without causing any adverse effects. (6)
More research is needed to determine the ideal curcumin formulation for aiding the repair of skin wounds.
Turmeric has been used as a disinfectant and skin-healing agent due to its inherent antiseptic and antibacterial properties.
2. Weight management
A study found that curcumin helped with the overall weight loss, loss of body fat, and reduction of weight circumference in those that had already successfully lost weight from following a healthy diet and exercising. (8)
3. Arthritis relief
Turmeric is replete with antioxidants that can help inhibit free radical activity and thereby curb the swelling and pain associated with such inflammatory conditions.
4. Diabetes control
Some studies found that turmeric may help moderate insulin levels and improve glucose control in patients with diabetes or pre-diabetes when taken in appropriate amounts. It may also help improve insulin resistance, which is a precursor for type 2 diabetes. (11)(12)(13)(14)
Note: This remedy is not to be used as a substitute for your anti-diabetic medication but as an adjunct to it. Always consult your doctor or pharmacist before taking turmeric or curcumin if you are on anti-diabetic medication, as intake of both may result in dangerously low blood sugar levels.
The curcumin found in turmeric has been found to improve blood sugar levels and the body’s natural insulin response, which can help both prevent and manage type 2 diabetes.

5. Proper digestion
Turmeric can stimulate your gallbladder to produce more bile to improve fat metabolism and overall digestion. This digestive aid helps reduce flatulence, bloating, and other discomforting symptoms of inflammatory bowel disease. (15)(16)
Caution: People with gallbladder diseases should not take turmeric, as it can stimulate the gallbladder to produce more bile and consequently worsen the condition.
Turmeric can aid digestion by reducing bloating and gas, stimulating bile production, and supporting the growth of beneficial gut bacteria.
6. Skin benefits
It is also credited with anti-neoplastic properties that inhibit the development of skin tumors.
Caution: One study found that the topical application of turmeric caused contact dermatitis in many individuals. (19) Thus, conduct a patch test before using this ingredient and stop its use if you notice any irritation.
Oral and topical use of turmeric may help relieve a number of skin conditions, but more research is needed to understand the proper dosage, safety, and efficacy of this remedy.

Turmeric vs. Curcumin
Turmeric is a plant with roots that are often used as a spice in cooking and herbal beverages. It is enjoyed in its whole and powdered form and is used both dried and fresh.
Curcumin is a compound found within turmeric’s roots and is responsible for turmeric’s characteristic yellow color. It is a carotenoid that exhibits strong antioxidant properties.
Turmeric is generally considered to be safe when taken orally as a spice in cooking or as a supplement or when applied topically to the skin.
High doses and long-term use of turmeric may lead to gastrointestinal problems. Also, exposure to turmeric may cause contact dermatitis.
A few studies found that participants developed abnormal liver function after taking turmeric or curcumin supplements for longer than 1 month. (31) People with gallbladder diseases should avoid taking turmeric.
