Street Food Cancer Risk: How Eating Samosas Fried in Reused Oil Can Raise Your Cancer Risk

Samosas are an irresistible part of Indian street food culture. Crispy, spicy, and flavourful, they’re enjoyed by millions every day. But what if your favourite snack is quietly harming your health? Experts warn that frequently eating samosas cooked in reused oil can significantly increase your risk of cancer and other serious diseases.

The Dark Side of Your Favourite Street Food


Samosas are loved across India - from Delhi’s bustling lanes to small-town tea stalls. They’re cheap, delicious, and satisfying. However, many street vendors use the same oil multiple times to save costs. This practice turns your beloved snack into a potential health hazard. The repeated heating of oil alters its chemical structure, creating compounds that are toxic to the body.

Why Reused Oil Is Dangerous


Health experts explain that repeatedly heating cooking oil produces free radicals and trans fats, both of which are harmful. Free radicals cause oxidative stress, damaging cells and increasing the risk of cancer, heart disease, and stroke.


  • The breakdown of fatty acids creates toxic substances like acrolein and polycyclic aromatic hydrocarbons (PAHs), which are known carcinogens.
  • Studies published in PubMed reveal that these compounds can increase the likelihood of gastric cancer and liver damage.
  • Reused oil also accelerates ageing and weakens your immune system.

Street Food: A Hidden Health Trap


Street vendors often reheat samosas and pakoras in the same oil used earlier in the day. While it helps them cut costs, it puts consumers at great risk. Food fried in burnt oil might taste fine, but the invisible toxins it contains can harm your body over time.
Regular consumption of such foods can lead to:

  • High cholesterol and heart problems
  • Liver dysfunction
  • Increased cancer risk

To protect your health, avoid foods fried in reused oil. Opt for snacks that are baked, grilled, or air-fried instead.


Healthier Alternatives You Can Try at Home


  • You don’t have to give up your love for snacks! Just make smarter choices:
  • Use fresh oil for every round of frying.
  • Try baking or air-frying samosas for a similar taste with less fat.
  • Add boiled or grilled snacks like corn, chana, or sweet potatoes to your diet.
  • Balance your meal with fresh fruits and fibre-rich foods to detoxify your system.

Eating a samosa once in a while won’t harm you - but making it a habit, especially from street stalls using reused oil, can silently damage your health. Prioritise fresh, homemade snacks to keep your body safe from the harmful effects of burnt oil and trans fats.
