This includes foods containing artificial thickeners and emulsifiers like polysorbate 80 and carboxymethylcellulose, which are present in foods including certain packaged ice creams and processed baked goods. Dr Sethi highlights that “emerging evidence linking emulsifiers to gut inflammation and gut barrier disruption” makes them harmful additives that should be avoided. Next time to buy an ice cream, make sure to check the back label for these ingredients!
High-fructose corn syrup is an artificial sweetener often present in condiments like ketchup and barbeque sauce. Dr Sethi recommends avoiding high-fructose corn syrup-laden products because they are “linked to liver fat accumulation” and can drive non-alcoholic fatty liver and other liver diseases.
Processed deli meats, including salami, sausages and other varieties preserved through curing, salting or smoking, can be harmful to your health when consumed regularly. These meats are commonly found in packaged and fast foods such as hot dogs, burgers and sandwiches, and are often high in calories, sodium and saturated fat while offering relatively little nutritional value. Moreover, Dr Sethi warns that processed meats rank high in “WHO Group 1 carcinogen classification for colorectal cancer.”
Beverages labelled as “diet drinks” are often made with artificial sweeteners such as sucralose and saccharin. The gastroenterologist strongly advises against consuming these “artificial sweetener-heavy diet drinks”, as they show the “strongest evidence of microbiome diversity loss.” This can ultimately affect your gut health, which plays a role in far more than just digestion.
Love eating a bowl of Chocos or Fruit Loops first thing in the morning? You might want to rethink that habit. According to Dr Sethi, these popular breakfast cereals are often packed with refined carbohydrates while being marketed as convenient or seemingly healthy breakfast options.
Ever get late for work and think you’ll just grab a protein bar on the way instead of sitting down for a whole-foods breakfast? While protein bars may seem like a convenient packaged option when you’re on the go, many are highly processed and can contain a long list of added ingredients that may not be ideal when consumed regularly. Dr Sethi highlights, “Long ingredients list equals red flag.”
Canned soups are another ultra-processed food that can be particularly high in sodium. The gastroenterologist cautions against making canned soups a regular part of your diet, warning that “excess sodium silently harms heart health.”
Red 40 and Yellow 5 are popular synthetic food dyes derived from petroleum used to improve product appearance. These colourants are often found in soft drinks, energy drinks, chips, candy, and breakfast cereals. The gastroenterologist emphasises “Red 40 and Yellow 5 in your kids’ snacks” are “linked to gut inflammation and hyperactivity.”
