Turmeric has achieved almost mythical status in the wellness world, credited with treating everything from arthritis to cancer to depression. You'll find it in lattes, capsules, golden milks, and beauty products. The reality is more nuanced than either the enthusiasts or the sceptics suggest. There's genuine science here — but also genuine limitations that the supplement industry has little incentive to advertise.
Curcumin: What It Is and What It Does
Turmeric's benefits are attributed primarily to curcumin, a polyphenol compound that makes up approximately 2–5% of the spice by weight. Curcumin has demonstrated significant anti-inflammatory and antioxidant activity in laboratory settings, inhibiting several inflammatory pathways including NF-kB — a key molecular switch in chronic inflammation — and reducing oxidative stress markers.
The anti-inflammatory activity is real and meaningful. Chronic low-grade inflammation underlies most of the major diseases of modern life — cardiovascular disease, type 2 diabetes, cancer, Alzheimer's disease, and depression. Reducing it is genuinely valuable.
The Bioavailability Problem
Here's the catch that the golden latte market rarely mentions: curcumin is poorly absorbed from the gut. When you eat turmeric, the vast majority of curcumin passes through without reaching the bloodstream in meaningful concentrations. A standard turmeric latte delivers a fraction of the curcumin used in research studies, which already account for this problem by using large doses in concentrated supplement form.
Black pepper — specifically its active compound piperine — increases curcumin absorption by approximately 2,000%. Traditional Indian cooking has combined turmeric and black pepper for thousands of years without knowing the biochemistry. Adding black pepper to turmeric-containing dishes is one of the simplest and most evidence-backed nutritional hacks available. Combining turmeric with fat also improves absorption, since curcumin is fat-soluble.
What the Evidence Actually Shows
Arthritis and joint inflammation: This is probably the strongest area of evidence. Multiple trials have shown that curcumin supplements (typically 500–1,000mg with piperine) reduce pain and improve function in osteoarthritis to a degree comparable with ibuprofen — with fewer gastrointestinal side effects. This is a clinically meaningful finding for people who need long-term anti-inflammatory support.
Metabolic syndrome: Curcumin has shown promising effects on blood sugar, insulin sensitivity, and blood lipid profiles in people with metabolic syndrome or type 2 diabetes. The effect sizes are modest but consistent.
Depression: Several trials have found curcumin reduces depression scores, likely through its effects on inflammatory pathways and on brain-derived neurotrophic factor (BDNF), a protein involved in neuronal growth and mood regulation. These studies used concentrated supplements, not dietary turmeric.
Cancer: Lab and animal studies show curcumin can inhibit cancer cell growth and induce apoptosis. Human clinical trials are at early stages and have not yet established curcumin as a cancer treatment. Claims that turmeric cures or prevents cancer are not supported by current human evidence.
Using Turmeric Practically
Incorporating turmeric into cooking as a spice is a sensible, evidence-consistent approach to increasing polyphenol intake — as part of a generally anti-inflammatory diet, not as a medical treatment. Curries, soups, rice dishes, scrambled eggs, roasted vegetables, and smoothies all absorb turmeric well. Always add black pepper.
For therapeutic purposes — if you're looking for meaningful anti-inflammatory effects for joint pain or metabolic health — dietary turmeric alone is unlikely to deliver sufficient curcumin. A standardised supplement with piperine, taken at evidence-based doses, is more appropriate. Discuss with your GP if you're taking blood-thinning medication, as curcumin has mild anticoagulant effects.
Turmeric in Filipino and Vanda's Kitchen Cooking
Turmeric has deep roots in Filipino and Southeast Asian cooking — it appears in traditional dishes as both a flavouring and a colouring agent, long before Western health food culture discovered its anti-inflammatory properties. Vanda's Kitchen's Filipino culinary heritage incorporates turmeric and other anti-inflammatory spices as natural elements of the cuisine rather than as health supplements added to otherwise standard food.
For City workers who want the evidence-based benefits of turmeric as part of their daily diet rather than as a supplement, Vanda's Kitchen's food provides a practical and delicious source. Our lunches incorporate anti-inflammatory ingredients naturally through the cuisine's culinary tradition. Read our anti-inflammatory diet guide and our Filipino cuisine health benefits post.
