Turmeric is a spice derived from the rhizomes (underground stems) of the turmeric plant, scientifically known as Curcuma Longa. It is native to Southeast Asia and is a member of the ginger family. Turmeric has been used for centuries in traditional Indian and Ayurvedic medicine as well as in culinary applications.
The active compound in turmeric that gives it its distinctive yellow colour and many of its health benefits is called Curcumin.
Turmeric is primarily grown in several regions of India, and the country is one of the largest producers and exporters of turmeric in the world.
The following states in India where turmeric is grown:
- Andhra Pradesh
- Tamil Nadu
- Maharashtra
- Odisha
- Telangana
- Karnataka
- Kerala
These states are known for their significant turmeric cultivation and production.
Here are some of the notable turmeric varieties cultivated in India:

Here are some of the potential benefits of turmeric:
- Anti-inflammatory properties: Curcumin is known for its potent anti-inflammatory effects. It may help reduce inflammation in the body, which is associated with various chronic conditions like arthritis, heart disease, and certain types of cancer.
- Antioxidant activity: Turmeric has antioxidant properties that can help protect the body from free radicals, which are unstable molecules that can damage cells and contribute to ageing and diseases.
- Potential pain relief: Some studies suggest that turmeric may help alleviate pain, particularly in conditions like osteoarthritis. It may have a similar effect to non-steroidal anti-inflammatory drugs (NSAIDs) but with potentially fewer side effects.
- Digestive health: Turmeric has been traditionally used to support digestion. It may help stimulate the production of bile, aid in the breakdown of fats, and alleviate symptoms of indigestion.
- Potential brain health benefits: Curcumin has shown promise in supporting brain health. It may help protect against age-related cognitive decline, improve memory and attention, and potentially reduce the risk of neurodegenerative diseases such as Alzheimer's.
- Potential heart health benefits: Some studies suggest that Curcumin may have a positive impact on heart health by improving blood vessel function, reducing inflammation, and lowering the risk of heart disease.
- Potential anticancer properties: Curcumin has demonstrated potential anticancer properties in preclinical studies. It may help inhibit the growth and spread of cancer cells, although more research is needed to fully understand its effects.
It's worth noting that the bioavailability of Curcumin is relatively low, meaning that the body has difficulty absorbing and utilising it. To enhance absorption, turmeric is often consumed with black pepper or combined with fats, such as coconut oil or olive oil.
While turmeric can be a beneficial addition to a balanced diet, it's important to consult with a healthcare professional before using it for therapeutic purposes, especially if you have any existing health conditions or are taking medications. They can provide personalised advice and guidance based on your specific situation.
Some common ways to incorporate turmeric into your diet:
1. Spice in cooking: Turmeric is widely used as a spice in Indian, Southeast Asian, and Middle Eastern cuisines. It adds a vibrant yellow colour and a warm, earthy flavour to dishes. Turmeric is often found in curry powders and can be used to season a wide range of savory dishes, including curries, stir-fries, rice dishes, soups, and stews.
2. Turmeric tea or golden milk: Turmeric can be used to prepare a soothing and aromatic turmeric tea or golden milk. Simply mix a teaspoon of ground turmeric with hot water or warm milk (dairy or plant-based), add sweetener if desired, and enjoy. You can also add other spices like ginger, cinnamon, or black pepper for additional flavour.
3. Smoothies: You can add a teaspoon of turmeric powder or a small piece of fresh turmeric root to your favourite smoothie recipe. Blend it with other ingredients like fruits, vegetables, yogurt, or plant-based milk for a nutritious and flavourful boost.
4. Turmeric supplements: Turmeric supplements are available in the form of capsules, tablets, or extracts. These supplements contain a concentrated dose of Curcumin, the active compound in turmeric. It's important to follow the recommended dosage instructions and consult with a healthcare professional before starting any new dietary supplements.
When consuming turmeric, it's worth noting that the absorption of Curcumin in the body can be enhanced by consuming it with black pepper or fats. Black pepper contains a compound called Piperine, which improves the bioavailability of Curcumin. Additionally, Curcumin is fat-soluble, so consuming it with healthy fats like coconut oil, olive oil, or avocado can enhance its absorption.
Remember that individual tolerances and sensitivities to turmeric may vary. Some people may experience gastrointestinal discomfort or allergic reactions, particularly when consuming large amounts or taking high-dose supplements. If you experience any adverse effects, it's advisable to discontinue use and consult with a healthcare professional.
