Kolkata, April 21, 2026 : Kolkata’s culinary landscape is a celebration of flavour, nostalgia, and tradition. From golden, puffed luchi paired with spiced aloor dom to indulgent kachoris and iconic mishti like rosogolla and sandesh, the city’s food culture is deeply woven into everyday life. While these foods are integral to Bengal’s identity, we are increasingly observing a concerning trend: a rise in liver-related disorders that may be linked, in part, to dietary habits.This raises an important question—can Kolkata’s enduring love for fried foods and sweets be impacting liver health?
Liver is one of the most vital organs in the human body, responsible for over 500 essential functions. It plays a central role in metabolising fats, processing sugars, detoxifying harmful substances and regulating energy balance. However, the liver is also vulnerable to dietary excess. Diets high in saturated fats, trans fats and refined sugars can overwhelm its metabolic capacity. Over time, this leads to fat accumulation within liver cells—a condition known as Non-Alcoholic Fatty Liver Disease (NAFLD). NAFLD has emerged as one of the most common liver disorders globally and is increasingly prevalent in urban Indian populations.
Traditional Bengali cuisine is diverse and balanced when consumed in its original form. However, modern dietary patterns have shifted toward frequent consumption of deep-fried foods such as luchi, kachori, telebhaja; high intake of sugar-rich sweets like in increased portion sizes and frequency of indulgence. And with reduced physical activity, these patterns are contributing to metabolic stress on the liver.
Impact of fried foods on liver health
Deep-fried foods are typically rich in unhealthy fats, particularly when cooked in repeatedly heated oils—a common practice in commercial and street food settings. From a clinical standpoint, excessive intake of fried foods can increase fat deposition in liver cells, promote oxidative stress and inflammation and contribute to insulin resistance. These changes are key drivers in the development of NAFLD. Over time, simple fatty liver can progress to more serious conditions such as non-alcoholic steatohepatitis (NASH), fibrosis and even cirrhosis. Additionally, trans fats generated during high-temperature frying are particularly harmful. They not only affect liver health but also increase cardiovascular risk, creating a dual burden of disease.
Hidden danger of excess sugar
Kolkata’s celebrated sweet culture presents another significant concern. Most traditional sweets are high in refined carbohydrates and sugars, particularly sucrose and fructose. Unlike glucose, which is utilised by multiple tissues, fructose is primarily metabolised in the liver. Excess fructose intake leads to increased fat synthesis within the liver (de novo lipogenesis), accumulation of triglycerides and development of insulin resistance. Clinically, this translates into a higher risk of fatty liver disease, even in individuals who are not overweight—a phenomenon often referred to as “lean NAFLD.”Regular consumption of sugar-laden sweets, especially in combination with sedentary habits, accelerates this process.
Urban health concern
In clinical practice, there has been a noticeable increase in young and middle-aged patients presenting with fatty liver. Alarmingly, many are asymptomatic and are diagnosed incidentally during routine health check-ups or imaging studies. Risk factors commonly observed include diets high in fried and sugary foods, sedentary lifestyle, abdominal obesity and Type 2 diabetes and dyslipidaemia. Kolkata, with its rich food culture and evolving urban lifestyle, reflects this broader national trend.
Early signs, symptoms often missed
One of the challenges with liver disease, particularly NAFLD (Non-Alcoholic Fatty Liver Disease), is its silent progression. Most patients do not experience symptoms in the early stages. When symptoms do occur, they may include like persistent fatigue, mild discomfort in the upper abdomen and unexplained weight gain or metabolic abnormalities Because these signs are non-specific, the condition often goes unnoticed until it has advanced.
Prevention
It is neither practical nor necessary to eliminate traditional foods from the diet. Instead, the focus should be on moderation and balance. From a medical and nutritional perspective, the following strategies are recommended:
1. Limit frequency of fried foods – Reserve deep-fried items for occasional consumption rather than daily intake.
2. Reduce sugar intake – Control portion sizes of sweets and avoid habitual consumption after meals.
3.Opt for healthier cooking methods- Steaming, grilling, and sautéing with minimal oil are preferable alternatives.
4. Increase dietary fibre and protein – Whole grains, vegetables, pulses, and lean proteins help improve metabolic health and reduce liver fat accumulation.
5. Maintain regular physical activity – At least 150 minutes of moderate exercise per week supports liver function and overall metabolism.
6. Routine health screening – Periodic liver function tests and ultrasound imaging can help detect early changes and prevent progression.
Food is central to Kolkata’s social and cultural fabric. Festivals, family gatherings, and daily rituals revolve around shared meals and cherished recipes. Therefore, public health messaging must be sensitive to this context. The goal is not to discourage traditional eating habits but to encourage mindful consumption. Small behavioural changes—such as reducing portion sizes, avoiding repeated oil use, and limiting daily sweet intake can have a meaningful impact on long-term health. Kolkata’s love for fried foods and sweets is a reflection of its rich heritage and vibrant lifestyle. However, in the backdrop of modern sedentary living, these dietary patterns can place a significant burden on liver health. The rising prevalence of Non-Alcoholic Fatty Liver Disease serves as a reminder that even time-honoured food traditions must adapt to contemporary health realities. With informed choices, moderation and regular medical monitoring, it is entirely possible to enjoy the flavours of Kolkata while safeguarding liver health. After all, the essence of good living lies not in deprivation, but in balance.
