According to statistics by National Cancer Centre Singapore, there were 87,716 cancer cases reported in Singapore if which 49% are males and 51% are females during the year of 2018-2022, with prostate cancer (17.4%) being the most common for male while breast cancer (29.6%) for female.However, do you know there are various foods, herbs and bioactive compounds that demonstrate abilities to combat cancer by reducing inflammation, inhibiting tumour growth and enhancing the immune system?

1. Curcumin (Turmeric)
Curcumin, the active compound in turmeric, is widely studied for its anti-inflammatory and antioxidant properties. Research suggests that curcumin can:
- Induce apoptosis (programmed cell death) in cancer cells.
- Inhibit angiogenesis (formation of new blood vessels that feed tumours).
- Reduce inflammation, a major factor in cancer progression.

2. Resveratrol (Grapes, Red Wine, Berries)
Resveratrol, a polyphenol found in grapes and berries, exhibits strong anti-cancer properties by:
- Preventing cancer cell proliferation.
- Enhancing the effectiveness of chemotherapy.
- Protecting DNA from oxidative damage.

3. EGCG (Green Tea)
Epigallocatechin gallate (EGCG) is a powerful catechin found in green tea with remarkable anti-cancer benefits, such as:
- Blocking tumour cell growth and spread.
- Reducing oxidative stress.
- Boosting immune function against cancer cells.

4. Sulforaphane (Broccoli, Cruciferous Vegetables) 
Sulforaphane is a sulphur-rich compound found in cruciferous vegetables like broccoli, Brussels sprouts, and cabbage. It has been shown to:
- Detoxify cancer-causing substances in the body.
- Induce apoptosis in cancerous cells.
- Reduce inflammation linked to tumour growth.

5. Quercetin (Onions, Apples, Citrus Fruits) 
Quercetin is a flavonoid with antioxidant properties that may help in:
- Suppressing cancer cell growth.
- Reducing inflammation and oxidative stress.
- Enhancing the effectiveness of chemotherapy.

Below are several mechanisms used by the compounds to fight those cancer cells:
- Apoptosis Induction: Encouraging the self-destruction of cancer cells.
- Anti-Angiogenesis: Preventing tumours from developing new blood vessels.
- DNA Protection: Reducing mutations and oxidative damage to cells.
- Immune System Boosting: Enhancing the body's natural defense against cancer cells.
Try to incorporate these natural ingredients into your diet:
- Drinking green tea daily for its EGCG content.
- Adding turmeric (curcumin) to meals with black pepper to enhance absorption.
- Consuming a variety of colourful fruits and vegetables rich in polyphenols and antioxidants.
- Eating cruciferous vegetables regularly to benefit from sulforaphane.
- Taking supplements that contain these natural ingredients for maximum bioavailability and enhanced absorption of its key active compounds.
By fueling your body with nature’s best, you’re paving the way for a resilient and youthful future.
