Extreme Diets Can Harm Liver, Gut: Balance is Key, Says Expert
Eliminating oils and extreme diets can damage liver and gut health.
Top Summary
- What happened: Dr. Ajay Kumar warns against extreme diets that eliminate oils, citing potential harm to liver and gut health.
- Why it matters: Restrictive diets can lead to nutritional deficiencies, weaken immunity, and affect overall health.
- What changes for people: Encourages balanced nutrition, dietary diversity, and moderation over restrictive eating habits.
- Who is affected: Individuals following or considering extreme diets for health benefits.
The Danger of Extreme Diets
Dr. Ajay Kumar, Chairman, Pan Max Gastroenterology & Hepatology, cautions against the popular trend of eliminating oils and consuming only sprouts, salads, and fruits.
He states that these extreme diets often fail to deliver expected health outcomes, leading to unforeseen complications.
"As a liver specialist, I meet many patients who attempt these restrictive diets in the hope of achieving perfect health, only to discover that extremes rarely produce the outcomes they expect," says Dr. Kumar.
Rethinking the Role of Edible Oils
Edible oils are often unfairly demonized, but they play a crucial role in maintaining good health.
Healthy oils like mustard, coconut, and olive oil provide essential fatty acids and fat-soluble vitamins A, D, E, and K that the body cannot produce independently.
Removing these oils can cause nutritional deficiencies, weakening immunity and impacting hormone production and cell repair.
"Decades of research on dietary patterns, including the Mediterranean diet, show that the inclusion of healthy fats contributes to a lower risk of chronic diseases," Dr. Kumar points out.
Dietary Diversity and Gut Health
Reduced agro-diversity has impacted dietary diversity, affecting gut health.
A varied gut microbiota is crucial for overall well-being.
"This matters because dietary diversity directly influences gut diversity," explains Dr. Kumar.
Common diseases like type 2 diabetes, obesity, and inflammatory bowel disease are associated with reduced microbiome richness.
The Role of Antioxidants and Inflammation
Inflammation is a key driver of many chronic conditions. Certain oils play a role in reducing inflammation.
Oils like extra-virgin olive oil, sunflower oil, palm oil, and fish oil have been studied for their anti-inflammatory properties.
Palm oil, in particular, contains beneficial compounds like tocotrienols and carotenoids.
"Tocotrienols, a form of vitamin E, have strong antioxidant and anti-inflammatory properties that may help protect the liver in several disorders," Dr. Kumar notes.
Why One-Size-Fits-All Diets Don’t Work
Responses to oils vary based on genetics, age, sex, and medication use.
Variations in the liver protein HNF4α influence how the body metabolizes fats.
Dietary advice should consider biological differences rather than following one-size-fits-all claims.
The One Oil Practice to Avoid
Recycled cooking oil, commonly used in small restaurants and street food stalls, poses a significant health risk.
"Recycled cooking oil, widely used in small restaurants and street food stalls, has been shown to cause extensive tissue damage in long-term animal studies," warns Dr. Ajay Kumar.
Avoiding food cooked in repeatedly heated oil is strongly advised.
Balance Over Extremes
Chronic diseases result from a combination of genetics, environment, lifestyle choices, physical activity, sleep, and overall diet quality.
No diet built on extreme restrictions can guarantee lifelong protection from disease.
"What truly supports long-term gut and liver health is a holistic approach built on variety, portion control, and balanced nutrition," he emphasizes.
Consider potlucks to control ingredients, portion sizes, and enjoy a variety of foods.
What to Watch Next
Future research will likely focus on personalized nutrition plans that account for individual genetic and metabolic differences. Look for studies examining the long-term effects of various dietary patterns on gut microbiome diversity and liver health, and continued investigation of the benefits and risks of specific edible oils.
