Many Yogurts Have More Sugar Than Soda, According To Harvard Gastroenterologist

Not all fermented foods are healthy for you. In fact, many <span>yogurts have more sugar than soda</span>. Dr. Saurabh Sethi, a <span>gastroenterologist</span> trained at AIIMS, Harvard, and Stanford, recently shared on Instagram that the fermented food that you get from supermarket, like pickles, in fact do not have live bacteria in it. So, in a way they do not help your <span>gut health</span> at all. 

Fermented foods like kimchi, yogurt, and kombucha have become wellness buzzwords, often praised for their gut-healing powers. But not everything marketed as “fermented” or “probiotic” actually benefits your digestive system. 

To clear up the confusion, Dr Sethi, recently shared on Instagram the seven most common mistakes people make when eating fermented foods, and how to enjoy them safely.

<h2>Not All Fermented Foods Have Live Probiotics</h2>

One of the biggest misconceptions is assuming that every fermented product is rich in probiotics. Dr Sethi points out that most packaged pickles on store shelves don’t contain live bacteria. The real probiotic powerhouses are kefir, yogurt, dahi, buttermilk, kimchi, and sauerkraut. If you’re looking for gut-friendly microbes, stick to these options rather than vinegar-based or shelf-stable pickles.

It’s important to know that probiotics are delicate. When foods like kimchi or sauerkraut are cooked, their beneficial bacteria die off. That means adding sauerkraut to hot soups or frying kimchi with rice won’t give you the probiotic boost you expect. 

Traditional Indian foods like idli, dosa, and dhokla are made through fermentation, which improves digestibility, but most live cultures don’t survive steaming or frying. To get the probiotic benefits, eat fermented foods raw or in minimally processed forms.

This is where most people go wrong. Many store-bought yogurts are marketed as “healthy” but contain more sugar than a can of soda. Worse, not all have live cultures. Dr Sethi recommends checking the label for the phrase “live and active cultures.” Without that, you’re mostly just eating flavored dessert. If possible, choose plain yogurt, homemade dahi, or sugar-free varieties.

Even if you pick the right foods, sticking to just one won’t maximize your gut health. For example, eating the same yogurt every day introduces only a limited range of bacteria. The gut microbiome thrives on diversity. Dr. Sethi suggests rotating between kefir, kimchi, miso, sauerkraut, and kanji to expose your digestive system to a broader spectrum of beneficial microbes.

<h2>Fermented Doesn’t Mean a Cure-All</h2>

Probiotics are helpful, but they are not magic. Fermented foods support gut health, but they cannot replace the benefits of fibre, fruits, vegetables, and a balanced diet. Over-relying on kombucha or kimchi while ignoring whole grains and fresh produce won’t give you long-term digestive health. Think of fermented foods as one piece of the puzzle, not the entire solution.

Adding too many probiotics too quickly can overwhelm your system. Gas, bloating, and stomach discomfort are common when you suddenly increase your intake. Dr. Sethi advises starting small, just a few spoonfuls of fermented food daily, and then gradually increasing the amount as your gut adjusts.

Not every jar labeled “fermented” actually contains probiotics. Shelf-stable pickles and chutneys, often preserved with vinegar or pasteurization, usually have no live bacteria left. For real probiotic benefits, choose refrigerated options such as fresh pickles, sauerkraut, kimchi, yogurt, or homemade drinks like dahi, lassi, and kanji.
