What Is the NOVA Classification System?
Walk into any Indian supermarket and you will find thousands of packaged food products. Some are healthy. Many are not. But how do you tell the difference between a packet of rolled oats and a box of flavoured breakfast cereal? They both come in boxes. They both claim to be nutritious. The answer lies in a framework called NOVA classification.
The NOVA food classification system was developed by researchers at the University of São Paulo, Brazil, led by Professor Carlos Monteiro. Unlike traditional nutrition analysis that focuses on individual nutrients (calories, fat, sugar), NOVA classifies foods based on the extent and purpose of industrial processing they undergo.
This is a fundamental shift in how we think about food. NOVA does not ask "how much sugar does this contain?" It asks "how far is this product from actual food?"
The World Health Organization (WHO), Food and Agriculture Organization (FAO), and the Pan American Health Organization (PAHO) all use the NOVA classification system in their dietary guidelines and research.

NOVA divides all food into four groups based on processing level. Here is what each group means, with examples from everyday Indian kitchens.
Natural foods with no or minimal alteration
Indian examples: Fresh fruits, vegetables, toor dal, basmati rice, milk, eggs, fresh chicken, fish, nuts, whole spices
Score boost in PraanSubstances extracted from Group 1 foods
Indian examples: Mustard oil, groundnut oil, ghee, butter, salt, sugar, jaggery, whole spice powders, vinegar
Neutral impactGroup 1 foods modified with Group 2 ingredients
Indian examples: Aachar (pickles), canned vegetables, paneer, cheese, freshly baked bread, salted nuts, dried fruit
Moderate impactIndustrial formulations with 5+ ingredients
Indian examples: Instant noodles, packaged chips, soft drinks, biscuits, breakfast cereals, packaged bread, ready meals
Major health concernThe critical distinction is between NOVA 3 (processed) and NOVA 4 (ultra-processed). Processed foods like pickles or cheese are recognizable modifications of whole foods. Ultra-processed foods are industrial formulations — they contain substances not found in home kitchens: emulsifiers, humectants, flavour enhancers, hydrogenated oils, high-fructose corn syrup, and a range of cosmetic additives designed to make industrial products look, taste, and feel like real food.
The Indian Market Reality
The situation in India's packaged food market is stark. Research analysing thousands of packaged food products sold across India reveals a troubling distribution.

Percentage breakdown of packaged food products by NOVA classification
That means more than half of all packaged food products available in Indian stores are ultra-processed. Only 12% qualify as unprocessed or minimally processed. The remaining 31% fall into the processed culinary ingredients and processed food categories.
What makes this particularly concerning is the trajectory. India's ultra-processed food market has grown by 13.4% annually over the past decade, driven by urbanisation, rising incomes, aggressive marketing, and the convenience these products offer to time-pressed households. The growth rate is among the fastest in the world.
India's per capita consumption of ultra-processed foods has nearly doubled in the last decade, with urban consumption growing at 2.5 times the rate of rural areas.

The growing body of evidence against ultra-processed foods is now impossible to ignore. What was once a fringe concern in nutrition science has become one of the most well-documented public health findings of the decade.
The BMJ 2024 Meta-Analysis
In February 2024, The BMJ published a landmark umbrella review — the most comprehensive study on ultra-processed foods to date. The meta-analysis examined 45 pooled analyses involving nearly 10 million participants and found convincing evidence that higher UPF consumption is linked to 32 adverse health outcomes, including:
- Cardiovascular disease: 50% higher risk of cardiovascular disease-related mortality
- Type 2 diabetes: 12% increase in risk for every 10% increase in UPF intake
- Mental health: 53% higher risk of anxiety and 48-53% higher risk of common mental disorders
- Cancer: Increased risk of overall cancer, particularly colorectal cancer
- Obesity: Significantly higher risk of obesity and weight gain
- All-cause mortality: 21% higher risk of death from any cause
Why This Matters Especially for India
India is already in the grip of a diabetes epidemic. With over 101 million people living with diabetes and another 136 million in the pre-diabetic stage, India has the second-highest diabetes burden globally. The rapid adoption of ultra-processed foods is adding fuel to this crisis.
The mechanisms are well understood. Ultra-processed foods are designed to be hyper-palatable — combinations of sugar, salt, fat, and flavouring that override our natural satiety signals. They are calorie-dense but nutrient-poor. They displace traditional Indian meals (dal-chawal, roti-sabzi, sambar-rice) that are naturally balanced and nutrient-rich.
Common Ultra-Processed Foods Indians Eat Daily
Many families do not realise how many ultra-processed foods have quietly entered their daily diet. Here are some of the most common NOVA 4 products consumed across Indian households.
| Product | Category | NOVA | Key Concern |
|---|---|---|---|
| Maggi 2-Minute Noodles | Instant Noodles | NOVA 4 | Refined flour, MSG (E621), high sodium (860mg/serve) |
| Parle-G, Good Day | Packaged Biscuits | NOVA 4 | Refined flour, palm oil, added sugar, emulsifiers |
| Coca-Cola, Thums Up | Soft Drinks | NOVA 4 | High-fructose corn syrup, phosphoric acid, caramel colour |
| Kellogg’s Chocos, Bagrry’s Flavoured | Breakfast Cereals | NOVA 4 | Added sugar (30-40%), artificial flavours, BHT |
| Harvest Gold, Britannia Bread | Packaged Bread | NOVA 4 | Emulsifiers (E481, E471), preservatives, added sugar |
| Lay’s, Kurkure | Packaged Chips/Snacks | NOVA 4 | Flavour enhancers, high sodium, acrylamide from frying |
The common thread across all these products: long ingredient lists dominated by industrial substances that you would never find in a home kitchen. Emulsifiers, stabilisers, flavour enhancers, hydrogenated fats, and cosmetic additives like artificial colours are hallmarks of ultra-processing.
How to Reduce Ultra-Processed Food Intake
The goal is not perfection. It is awareness and gradual replacement. Here are practical, India-specific strategies for reducing ultra-processed food consumption in your household.
Smart Swaps for Indian Families
Ready in 20 minutes. Dal + rice + vegetables. NOVA 1. Complete protein, fiber, and minerals.
Whole fruit retains fiber. Nimbu paani with jaggery is natural and hydrating.
High protein, low calorie snacks. Season with chaat masala for flavour.
Traditional Indian breakfasts. Minimally processed, nutrient-dense, ready in 15 minutes.
Natural probiotics in chaas. Coconut water has electrolytes without added sugar.
Roasted peanuts, murmura chivda, or dry fruits. Control oil, salt, and ingredients.
Practical Tips for Everyday Life
- Read the ingredient list, not just the nutrition label. If it has more than 5 ingredients, or contains substances you cannot pronounce, it is likely ultra-processed.
- Cook one more meal at home per week. Even replacing one restaurant or packaged meal with a home-cooked alternative reduces UPF intake measurably.
- Stock your kitchen with NOVA 1 foods. If your pantry has dal, rice, atta, vegetables, eggs, and fruits, the default becomes real food.
- Be sceptical of health claims on packages. "High protein," "whole grain," and "no added sugar" labels appear on many ultra-processed products. These claims do not change the NOVA classification.
- Involve children early. Kids who learn to distinguish between real food and ultra-processed food make better choices lifelong.
How Praan Shows NOVA Levels
Understanding NOVA classification should not require a food science degree. That is exactly why Praan integrates NOVA classification into every product scan.
NOVA Classification in Your Pocket
When you scan any packaged food product with the Praan app, the NOVA classification is displayed prominently alongside the overall health score. Here is how it works:
- Instant NOVA identification: Every scanned product shows its NOVA group (1, 2, 3, or 4) with a clear visual indicator
- Score integration: NOVA level contributes 20% of the overall Praan health score. NOVA 1 foods get a significant score boost; NOVA 4 foods receive a penalty
- Context, not just numbers: Praan explains why a product received its NOVA classification, listing the specific ultra-processed ingredients found
- Better alternatives: For NOVA 4 products, Praan suggests healthier alternatives in the same category with lower processing levels

The Bottom Line
The NOVA classification system gives us a powerful lens to evaluate food beyond misleading marketing claims. In India, where 57% of packaged food products are ultra-processed and diabetes affects over 100 million people, understanding this classification is not academic — it is urgent.
The solution is not to eliminate all packaged food from your life. That is neither practical nor necessary. The solution is to be aware of what you are eating, understand the difference between food that nourishes and industrial formulations designed to sell, and make informed choices that add up over months and years.
Every product you scan with Praan shows its NOVA classification. Every score reflects the degree of processing. The information is there. The choice, as always, is yours.
