Cinnamon, ginger and turmeric: food, evidence and caution

Cinnamon, ginger and turmeric can add flavour to food. This combination is not an established daily protocol for treating inflammation, controlling blood sugar or boosting energy. A pinch of spice in lunch is not the same as a capsule of concentrated extract tested in studies. This guide helps you use them sensibly in the kitchen.

What the evidence says

NCCIH states that it is unclear whether cinnamon helps with diabetes, partly because studies often do not say which type of cinnamon was tested. For ginger there is research on nausea in pregnancy, mostly with supplements rather than food. For turmeric and curcumin, NCCIH concludes that not enough is known to confirm a benefit for any health purpose.

Simple ideas for the kitchen

1. Sprinkle a little cinnamon on porridge or yoghurt, without extra sugar.
2. Grate fresh ginger into a vegetable stew, soup or marinade.
3. Add turmeric to lentil soup, risotto or vegetables cooked with a little oil.
4. Choose according to taste and tolerance. There is no need to use all three spices every day or to take them on an empty stomach.

When to be careful

Cassia cinnamon contains coumarin, which in large amounts can affect the liver, while Ceylon cinnamon has only traces. Ginger can cause heartburn and stomach discomfort. NCCIH warns that liver damage has been reported with some curcumin supplements with increased absorption, including those with piperine from black pepper. Before taking a concentrated supplement, talk to a doctor or pharmacist if you take medicines, have liver disease, are pregnant or breastfeeding. If you notice tiredness, nausea, dark urine or yellowing of the skin, stop the supplement and see a doctor.
