Dr Saurabh Sethi, a California-based gastroenterologist trained at AIIMS, Harvard, and Stanford, is well-known for sharing practical health tips on social media. In an Instagram post shared on June 26, the gut health expert revealed 11 science-backed habits for eating healthier, based on ancient wisdom and long-term research.

“Most people think healthy eating is about cutting things out. But it’s more about what you consistently add in — and how your gut responds. These are the same tips I give my patients. Simple, research-backed, and designed to actually work long term,” he said.

Here’s a closer look at the habits he recommends:

1. Incorporate Herbs and Spices that Support Gut Health

Ginger: Aids digestion
Turmeric + Black Pepper: Anti-inflammatory combo
Fennel Seeds: Reduce bloating
Cinnamon: Helps balance blood sugar
Peppermint: Soothes IBS
Tip: Add these to meals or tea for their gut benefits.

2. Avoid Processed Meats
Dr Sethi warns that bacon, smoked sausages, and cured hams raise colorectal cancer risk, especially in younger adults.

3. Choose Smoothies over Juice
Smoothies retain the fruit’s fiber, leading to slower sugar absorption and a healthier gut compared to fruit juice.

4. Don’t Fear Eggs
A 2018 study of 500,000 adults found one egg per day may reduce heart disease risk. Moderation is key if you have high cholesterol.

5. Be Smart about Sugar Cravings
“Strict diets can lead to bingeing,” Dr Sethi explains. Instead, opt for smaller portions of treats you love. Dark chocolate is a better option than milk chocolate.

6. Avoid Ultra-Processed Foods
These foods can double bacterial toxins in your blood and drive gut inflammation due to emulsifiers and artificial sweeteners.

7. Cut Down on Soda and Sugary Drinks
A long-term study of 100,000 nurses revealed that consuming just one sugary drink per day during adolescence increased early-onset colon cancer risk by 32%.

8. Make Fibre Your Best Friend
Most adults fall short of the daily 22–34 g fiber requirement. Adequate fiber supports gut health, regularity, and long‑term cancer prevention.

9. Pick Better Animal Proteins
The Mediterranean-style approach works best:

✅ Fish, yogurt, chicken
❌ Limit red meat
Consuming fish weekly is linked to a 7% lower colorectal cancer risk.

10. Try Plain Greek Yogurt
Greek yogurt is rich in protein, calcium, and vitamin D — with twice the protein and half the carbs of regular yogurt. Enhance its flavor by adding nuts, seeds, or fresh fruit.

11. Choose Gut-Friendly Whole Grains Wisely
Dr Sethi avoids brown rice due to its arsenic risk, and suggests alternatives like:
