Key Takeaways
- Plant-based diets significantly reduce multimorbidity risk of cancer and cardiometabolic diseases
- Studies show 35-70 age group benefits most from healthy plant-based nutrition
- Indian urban population faces high diabetes (16.4%) and insulin resistance (26%) rates
- Vegetarian and vegan diets offer both health benefits and environmental sustainability
A major international study reveals that adopting plant-based dietary patterns can substantially reduce the burden of multimorbidity – having multiple chronic conditions like cancer, diabetes, and heart diseases simultaneously. The research, analyzing data from over 400,000 individuals, provides compelling evidence for shifting toward plant-focused nutrition.
Groundbreaking Research Findings
Two significant studies published in 2024-2025 have transformed our understanding of diet and chronic disease prevention. The first, by V. Viallon and team in Scientific Reports (July 2024), established the Healthy Lifestyle Index connecting lifestyle factors with disease outcomes using EPIC study data.
The landmark research by Reynaldo Cordova and international collaborators in The Lancet – Healthy Longevity (August 2025) analyzed 2.3 lakh individuals from EPIC and 1.81 lakh from UK Biobank. Their findings demonstrate that healthy plant-based diets directly combat insulin resistance – the key mechanism behind metabolic diseases.
Plant-Based Benefits Beyond Health
The research confirms that plant-based dietary patterns offer dual advantages: superior health outcomes and environmental sustainability. Compared to animal-product heavy diets, plant-focused nutrition generates significantly lower greenhouse gas emissions while providing better protection against chronic diseases.
Higher adherence to healthy plant-based diets correlated strongly with reduced risks of:
- Various cancer types
- Cardiovascular diseases including hypertension
- Stroke and heart attack incidents
- Type 2 diabetes development
India’s Health Crisis and Dietary Patterns
The situation in India presents both challenges and opportunities. Approximately 35% of Indians follow vegetarian diets, while 10% maintain vegan practices. However, chronic disease rates remain alarming across urban and rural populations.
Current statistics reveal:
- 16.4% urban Indians have diabetes, with 8% rural population being pre-diabetic
- 26% urban men and women show insulin resistance with metabolic disorders
- 29% smoke tobacco products, increasing cancer risks
- Rural populations face additional oral cancer risks from betel nut chewing
- 13% of diabetics are over 60, often suffering dementia and Alzheimer’s
The Mediterranean diet, while beneficial, includes animal products like fish and chicken. Pure plant-based approaches show superior results for multimorbidity prevention.
Call to Action
Researchers emphasize that immediate attention from medical communities, policymakers, and society is crucial to address this growing health crisis. Adopting plant-based nutritional strategies could significantly reduce India’s chronic disease burden while promoting environmental sustainability.
