9 products secretly harmful to intestines

Yogurts with high sugar content

Yogurt is often advertised as a protein- and probiotic-rich food that supports gut health and immunity. In reality, some studies suggest that yogurt can alter the microbiome, gut barrier, and immune cells in the intestines.

However, many flavored yogurts are made with added sugar. Research shows that excessive sugar consumption can contribute to inflammation.

Instead of flavored yogurt, opt for plain Greek yogurt and add fresh fruit for natural sweetness.

If that's not an option, consider mixing 50% flavored yogurt with 50% plain yogurt. This way, you'll still enjoy the benefits of yogurt but with less sugar.

Sweetened diet drinks

Diet sodas with no sugar often contain artificial sweeteners, such as aspartame and sucralose. These can negatively impact the gut microbiome, reducing microbial diversity and potentially leading to metabolic issues.

If you enjoy sodas, it's better to choose ones with added fruit juice and no artificial sweeteners.

Kombucha with high sugar content

Kombucha is often praised for its probiotic content, but some brands add sugar to their drinks. Too much-added sugar can feed harmful bacteria in the gut, nullifying the potential benefits of this fermented tea.

Choose kombucha varieties that contain less than 5 grams of sugar per serving.

Fermented foods

Fermented foods like sauerkraut and pickles are great for gut health, but pasteurization kills the live bacteria.

Without live bacteria, these products may not have the same positive effect on the gut microbiome balance.

Studies show that even pasteurized fermented foods can contain microbial byproducts that are beneficial to human health, so choosing pasteurized fermented products still offers certain advantages.

Gluten-free products

Many gluten-free products are filled with additives like refined starches and emulsifiers. Studies have shown that emulsifiers in processed foods can damage the gut lining and trigger inflammation.

Additionally, many gluten-free products are low in fiber. Since fiber fuels beneficial gut microbes, products low in fiber are not as beneficial for the gut.

Always read the ingredient list and try to avoid those containing emulsifiers (e.g., carrageenan).

Protein bars

Protein bars are often packed with artificial flavors and sweeteners, which can disrupt digestion. Sorbitol can cause bloating, gas, and diarrhea in some people.

Moreover, non-nutritive sweeteners like sucralose can alter the composition of the human gut microbiome.

To increase your protein intake, try adding more eggs, yogurt, cheese, roasted chickpeas, tofu, beans, and protein-rich grains (such as quinoa) to your diet.

Plant-based milk

While plant-based milk can be a great alternative for many people, some varieties contain carrageenan or other emulsifiers that can cause irritation and inflammation in the gut.

Instant oatmeal

Instant oatmeal packets may seem like a healthy breakfast, but many contain added sugars and artificial ingredients.

This quick-cook product also contains more refined oats than regular oatmeal, which can lead to blood sugar spikes.

Choose regular oatmeal and add cinnamon, berries, and honey or maple syrup for natural sweetness.

Fruit juice with added sugar

Even fruit juices made without added sugar often contain high levels of fructose. When consumed in excess, this can lead to uncomfortable symptoms such as gas, bloating, and diarrhea, particularly in individuals with irritable bowel syndrome.

Instead of juice, make smoothies at home using whole fruits, leafy greens, and unsweetened yogurt.
