A rising debate around whether quinoa truly deserves its status as a superfood has resurfaced on social media after Harvard and Stanford trained gastroenterologist Dr Saurabh Sethi addressed some of the most common questions people ask about it. In a recently shared Instagram video, Dr Sethi unpacked both the benefits and the limitations of quinoa while urging viewers to make informed dietary choices rather than relying on hype.

Why Quinoa Has Become a Buzzword in Wellness Circles

Quinoa has become a global favourite among fitness enthusiasts, plant-based eaters, and those looking for gluten-free alternatives. From salads and bowls to desserts and cereal replacements, its rising popularity is often tied to claims about protein richness, heart health benefits, and metabolic support.

Responding to the ongoing debate, Dr Sethi asked the big question: “Quinoa, yes or no?” and then broke down the facts one by one in his video, discussing everything from amino acids to liver health. The insights were shared in a structured FAQ format in his Instagram post.


The Benefits: High Protein, Antioxidants, and Gut Health

According to Dr Sethi’s explanation in the video transcript, quinoa ticks several nutritional boxes that contribute to better metabolic and digestive health. He noted that quinoa is naturally gluten-free and is a strong source of protein along with essential amino acids. He also stated that it contains antioxidants that support heart and metabolic functions, and eating it can help improve insulin sensitivity and cholesterol levels.

On gut function, Dr Sethi highlighted that quinoa is beneficial because of its fiber content, supporting smoother digestion and overall gut wellness.

The Limitations: Not a Cure-All

Despite the hype around it being a wonder grain, Dr Sethi clarified that quinoa is not a medical solution for serious health issues. He emphasized that it cannot reverse fatty liver on its own. Addressing mental health claims, he mentioned that early research suggests quinoa may help mood and anxiety, although the findings are not yet conclusive.

He also dismissed the idea of consuming it raw. He explained that raw quinoa contains saponins that can cause bitterness and stomach irritation, hence it must always be cooked before eating.

Portion Guidance and Common Misconceptions

While some view quinoa as a grain substitute, Dr Sethi clarified that it is technically a pseudo-cereal. However, he added humorously that the body does not differentiate it that way while digesting. On recommended intake, he advised consuming half to one cup of cooked quinoa a few times a week for optimal benefits.

Dr Sethi is a board-certified gastroenterologist, hepatologist, and interventional endoscopist known for promoting lifestyle-centered wellness. With education spanning AIIMS, Harvard Medical School, and Stanford University, he has more than 25 years of experience in digestive and liver health. He is widely followed online for practical, evidence-based guidance on diet, sleep, and lifestyle habits that support gut health.

So, Is Quinoa Worth the Hype?

If consumed wisely and not treated as a miracle cure, quinoa appears to be a strong nutritional addition for many people, particularly those seeking plant-based protein or gut-friendly fiber. But as Dr Sethi’s Instagram video reminds viewers, balance, portion control, and evidence-driven understanding remain key to health decisions.

For now, quinoa stays on the superfood list, but with science, not trend culture, deciding its place.
