Effects of Air Pollution on Health: How Nutrition Can Protect Your Body

How Air Pollution Affects Human Health Beyond the Lungs

During peak pollution months in India—especially in Delhi-NCR and other urban regions—high AQI levels make daily life uncomfortable. Burning eyes, throat irritation, sinus congestion, breathlessness, headaches, and fatigue become common health complaints.

Air pollution contains fine particulate matter (PM2.5 and PM10) and toxic gases such as nitrogen dioxide, sulfur dioxide, and carbon monoxide. These pollutants penetrate deep into the lungs and can enter the bloodstream.

Beyond breathing difficulties, air pollution health problems include increased inflammation, oxidative stress, poor concentration, fatigue, and cardiovascular strain. Long-term exposure has also been linked to faster cellular ageing and worsening metabolic health.

A simple way to understand pollution is to think of it as internal “rusting.” Nutrition acts as a protective antioxidant shield, helping neutralize free radicals, reduce inflammation, and support liver detoxification.

Air Pollution Effects on Immunity and Inflammation

One of the most overlooked effects of air pollution on health is its impact on the immune system. Continuous exposure to polluted air increases oxidative stress and weakens immune cell function, making the body more susceptible to infections and inflammation.

This explains why many people fall sick more frequently during high AQI periods and why strengthening the connection between air pollution and the immune system through nutrition becomes essential.

Key Nutrients That Help Protect the Body from Air Pollution

Certain nutrients play a powerful role in reducing pollution-induced damage and supporting immunity:

• Vitamin C supports lung tissue and immune defenses.
  Sources: Amla, citrus fruits, guava, capsicum
• Vitamin E protects cell membranes from oxidative stress.
  Sources: Almonds, sunflower seeds, spinach
• Vitamin A (beta-carotene) helps maintain a healthy mucus lining in the airways.
  Sources: Carrots, pumpkin, sweet potatoes
• Omega-3 fatty acids reduce inflammation caused by pollutants.
  Sources: Flax seeds, walnuts, oily fish
• Zinc and Selenium strengthen immune response and antioxidant enzymes.
  Sources: Pumpkin seeds, cashews, eggs, whole grains
• Polyphenols help counter oxidative stress.
  Sources: Green tea, turmeric tea, berries

How to Protect the Body from Air Pollution Using Daily Meals

Including a variety of naturally coloured fruits and vegetables is especially important during high pollution exposure. Learn how eating a wide range of colours supports immunity and overall health in our detailed guide on the benefits of the rainbow diet .

• Half the plate should consist of colourful vegetables
• One quarter should include complex carbohydrates such as millets, oats, brown rice, or quinoa
• One quarter should include quality protein such as dal, paneer, sprouts, eggs, or lean meat
• Include one seasonal fruit, preferably rich in vitamin C
• Add a small handful of nuts or seeds daily

Sample Day During High AQI

• Breakfast: Warm lemon water or amla shot with moong dal chilla and a seasonal fruit
• Lunch: Brown rice with vegetable curry, dal, salad, and curd
• Evening: Nuts with green tea or tulsi tea
• Dinner: Light meal followed by turmeric milk or cinnamon water before bed

Hydration: Aim for 2.5–3 litres of water daily. Infused water with lemon, mint, or cucumber and herbal teas can add antioxidant benefits.

Functional Foods That Support Detoxification

Certain foods actively support the body’s natural detox pathways:

• Garlic and onion help in removing heavy metals
• Beetroot and spinach support liver enzyme activity
• Turmeric provides strong anti-inflammatory and antioxidant benefits
• Lemon and amla boost vitamin C intake

Foods to Limit During High Air Pollution

To reduce inflammation and oxidative stress, it’s best to limit:

• Deep-fried and processed foods
• Reheated or reused oils
• Sugary drinks and desserts
• Excess caffeine and red meat
• Refined carbohydrates

Lifestyle Habits That Enhance Pollution Resilience

Nutrition works best when combined with supportive lifestyle habits:

• Indoor exercise or yoga to reduce inflammation
• Nasal breathing practices such as alternate nostril breathing
• Adequate sleep (7–8 hours) to support immune repair and gut health

Common Questions Answered During the Webinar

• Does air pollution affect people with autoimmune conditions more?
  Yes. People with autoimmune conditions should avoid known triggers, focus on antioxidant-rich foods, and consult their doctor when needed.
• How can children be protected during high pollution days?
  Ensure good hydration, include colourful vegetables and fruits, and encourage indoor play during peak pollution hours.
• Are supplements necessary during high AQI periods?
  Short-term supplementation may help in some cases, but whole foods should always be the foundation.
• Does air pollution affect gut health?
  Yes. Pollution can disrupt gut balance. Including curd, sprouts, and fermented foods can help support gut health.

Why Personalized Nutrition Matters During Pollution Exposure

Air pollution does not affect everyone in the same way. Genetics, blood markers, lifestyle habits, and existing metabolic conditions influence how the body responds to polluted air.
