Mustard Oil vs Sunflower Oil: Which is Better?

Share with your network

In the perpetual quest for a healthier lifestyle, cooking oil plays a pivotal role. While it is true that nutritionists and dieticians all over the world are in favor of consuming less oil, it is also true that oil adds flavor to our food and serves as a rich source of fats and antioxidants. However, the debate intensifies when it comes to selecting the right oil for daily culinary needs. Among the array of options available, two commonly used oils in Indian kitchens, Sunflower Oil and Mustard Oil, often take centre stage.

Today’s article will discuss the pros and cons of two commonly used oils in the Indian kitchen—Sunflower Oil and Mustard Oil. Let’s find out from Delhi’s top Dietician, Avni Kaul, which of the two is better for your health in the long run.

Mustard Oil: A Brief Introduction

Mustard oil, from mustard plant seeds, is common in Indian cooking for its strong flavor and ability to handle high heat. It’s popular in India, Bangladesh, and Pakistan. But some countries ban it for cooking due to high erucic acid, which can harm the heart if consumed too much. Still, it’s used in skincare for massages, skin serum, and hair treatments.

Sunflower Oil: A Brief Introduction

Sunflower oil, extracted from the seeds of the sunflower plant (Helianthus annuus), is rich in polyunsaturated and monounsaturated fats, linoleic and oleic acids, and vitamin E. Ukraine and Russia collectively contribute to over half of the global production of sunflower oil. Certain varieties of sunflowers are cultivated specifically for their elevated oleic acid content. The resulting sunflower oil, known as high-oleic acid sunflower oil, serves as a vital dietary source of polyunsaturated fats.

What are the Pros of Mustard Oil?

Good for your heart–Due to the presence of MUFA or monounsaturated fatty acids, mustard oil reduces harmful cholesterol, regulates blood fat levels, and boosts circulation. Rich in omega-3 fatty acids, it lowers the risk of ischemic heart disease. Studies indicate MUFA’s ability to lower triglycerides, blood pressure, and blood sugar levels, benefiting heart health.

Antibacterial and anti-fungal properties–It has been found that mustard oil possesses potent antibacterial and anti-fungal properties. Whether used in cooking or applied externally, it can combat digestive infections and treat skin issues. Research suggests its efficacy in eliminating dental bacteria and preventing vaginal yeast infections.

Helps in reducing pain and inflammation–Mustard oil is thought to alleviate pain and inflammation due to the presence of allyl isothiocyanate, a chemical compound known for its impact on pain receptors, and alpha-linolenic acid, which may reduce inflammation and relieve pain associated with conditions such as rheumatoid arthritis. However, more research is still required to understand its safety and effectiveness.

Good for cough and cold– If you have a cold, some believe mustard oil can help. Rubbing it on your chest or inhaling steam with a few drops can ease symptoms. However, there’s no scientific evidence to support its effectiveness for respiratory issues.

What are the Pros of Sunflower Oil?

Lowers bad cholesterol and takes care of your heart– Since it is low in saturated fat and high in polyunsaturated fatty acids including omega-3s omega-6s and monounsaturated fatty acids, this oil can help lower blood levels of LDL (bad) cholesterol and triglycerides and promotes cardiovascular health.

  • Good for your nerves– Vitamin E present in this oil may slow the progression of Alzheimer’s Disease.
  • Hair Treatment– Tocopherol present in this oil helps to treat hair problems like baldness and excessive hair fall.

What about the Cons of Mustard Oil?

Excessive consumption of Mustard oil has its own risks. It may cause erucic acid toxicity, linked to cardiovascular issues, diarrhoea, anaemia, and respiratory problems. Allyl isothiocyanate in mustard oil irritates the mouth and gut lining. Prolonged exposure to erucic acid in animals causes myocardial lipidosis. It can also affect children.

What about the Cons of Sunflower Oil?

Sunflower oil, rich in fatty acids, is calorie-dense and may lead to obesity-related health issues. Heating certain types can release harmful compounds, contributing to inflammation. Its omega-6 and omega-3 content may promote weight gain. Excessive consumption elevates blood sugar and cancer risk.

Takeaway
It is evident from this analysis that both mustard oil and sunflower oil have their merits and demerits. The choice between them depends on individual health needs and cooking preferences.

Avni approaches nutrition and wellbeing in a genuinely scientific and highly customized way. Her knowledge is impressive, but what truly stands out is the personalized element—it's clearly not a rigid, one-size-fits-all plan. I really appreciate that the process is designed to be flexible and adaptable to individual preferences and lifestyles. Beyond the methodology, the attention to detail and the support system she sets up are exceptional. She ensures the journey of nutritional improvement doesn't feel weary or lonely. Loved the gamification elements which made the process fun while encouraging a focus on sustainable, long-term habits. Would definitely recommend!!

When looking for someone to help you through your health journey, I think it is very important that the people who are guiding you do not approach it with any judgement. That is one of the best things I find about Avni & her team. They don't make food your enemy but rather teach you how to do it right, spending a lot of time in understanding your likes and dislikes and really personalising it to your need. You can be sure that you are being looked after individually. Alongside that, they also offer is a wealth of knowledge but also a delicate approach towards your journey. This is the main reason why I would recommend Avni to everyone.

In March 2025, I had a scare with a sudden spike in my sugar levels. That was my wake-up call—I knew it was time to take my health seriously. I wasn’t looking for a quick fix but a long-term, sustainable lifestyle change. That’s when a close friend introduced me to Avni and NutriActivania. I reached out to Avni, and we discussed my goals and what I hoped to achieve. She and her team immediately put together a plan tailored specifically for me. The best part was how flexible it was—no drastic cuts, no extreme measures. Instead, they focused on equipping me with the skills and habits I needed to make lasting lifestyle changes. They listened to what worked for me, especially in terms of food preferences, and built a plan around my life rather than expecting me to adjust to theirs. That level of customization is what made it easy for me to stay committed. Each week, they share a personalised food plan and always check in before finalizing it. Avni has been incredibly supportive—always available to answer questions and consistently encouraging me to stay on track. Over the last seven months, I have lost 9 kgs. My sugar levels are back to normal, my cholesterol has dropped, and most importantly, I feel healthier. I eat better, and I am far more mindful about what I consume. I truly believe they’ve given me the tools to make better choices and have been instrumental in helping me reshape my lifestyle. Thank you, Avni and team. Thank you for being part of my journey and for helping shape it in the best way possible.

During my first pregnancy, I was worried because I didn’t know how to give proper nutrition to my baby. Someone suggested Nutritionist Avni Kaul, so I joined her program and followed her diet plan throughout my pregnancy. She gave me a healthy meal plan that also allowed me to enjoy the foods I liked. My baby girl was born healthy and at a good weight. After pregnancy, I struggled with my weight, so I joined Avni Kaul’s post-pregnancy weight loss program. My weight went from 65 kg to 56 kg. I truly thank Nutri Activania and Nutritionist Avni Kaul for their support and guidance during my pregnancy and weight loss journey.

I visited Nutritionist Avni after struggling for months with low energy and irregular eating habits. She gave me a diet plan that was flexible, not restrictive, and I started feeling the difference in my energy levels within just a couple of weeks.
