A Harvard-trained doctor has issued a stark warning about common foods that he claims are “silently poisoning” our bodies.
Dr Saurabh Sethi, 43, regularly shares health insights with his 1.4 million followers on Instagram.
The gastroenterologist previously rated nine ‘superfoods’, including green tea and olive oil, for their anti-ageing benefits.
Now, he has delivered a warning over certain everyday items – with strawberries topping the list.
Dr Sethi is certified by the American Board of Internal Medicine and has completed fellowships through both Stanford and Harvard.
“You get the most pesticide exposure from strawberries,” he said.
“Certain pesticide residues may interfere with hormone signalling and add to the body’s cumulative chemical exposure over time.”
The most microplastic exposure comes from bottled water, he said.
“Microplastics are tiny particles that may accumulate in the body and are being studied for their potential effects on gut barrier health and inflammation.
“And heavy metal from canned tuna means mercury can build up in the body.
“With frequent intake, it may affect the brain and nerve function, especially when exposure becomes excessive.”
He also lists acrylamide – a chemical compound that is potentially carcinogenic – from deep-fried potatoes, including crisps.
This forms when starchy foods are cooked at high temperatures.
He added: “Added chemical preservatives [come] from ultra-processed meats.
“These additives can alter the gut microbiome and have been linked to higher levels of systemic inflammation when eaten regularly.
“And advanced glycation end products come from charred meats.
“These compounds form during charring and can promote oxidative stress.
“This is associated with faster biological ageing.”
People get the most sodium nitrate exposure from hot dogs and deli meats, he said.
“In the body, nitrates convert into reactive compounds that may affect vascular and metabolic health when intake is frequent.
“Artificial dyes are found in colorful cereals and candies.
“And in children, synthetic food colours have been linked to hyperactivity-type symptoms; so reducing intake may help sensitive individuals.
“This isn’t about fear – it’s about awareness.
“Once you know the source, you can make smarter food choices that protect your gut, liver, hormones and long-term health.”
