4 ‘Healthy’ Foods That Can Actually Damage Your Gut And Expand Your Waistline: Granola Bars & More

Gut health is a crucial aspect of overall well-being and plays a significant role in weight management. A balanced gut microbiome aids digestion, boosts metabolism, and helps regulate body weight. However, not all foods labeled as “healthy” are beneficial for your gut or your waistline. It’s essential to be mindful of certain foods that may appear nutritious but can actually cause digestive issues and contribute to weight gain.

So, what are some of the biggest culprits that may be pulling the wool over your eyes? To find out, we spoke to health experts Krutika Nanavati , registered dietitian and nutritionist; Paula Doebrich , RDN; and dietitian Marie Murphy, CEO of MEM Nutrition and Wellness . From dried fruit to sweetened yogurt, these common items could be undermining your efforts to maintain a healthy gut and achieve your weight loss goals. Understanding the hidden pitfalls of these foods will help you make better choices and support your journey to a healthier you.

1. Dried Fruit

While dried fruit contains essential vitamins, minerals, and fiber, it's also concentrated in natural sugars and calories. Consuming large quantities of dried fruit can lead to spikes in blood sugar levels, contributing to insulin resistance and weight gain around the stomach.

When it comes to gut health, Nanavati says, "While dried fruit offers vitamins and minerals, its higher natural sugar concentration compared to fresh fruit can disrupt gut bacteria balance, causing bloating. Certain dried fruits may contain sulfites, which are preservatives that could potentially contribute to imbalances in the gut microbiome and digestive problems in sensitive individuals."

This can also impact weight, as she says, "Despite its small serving size, dried fruit contains a surprisingly high number of calories due to the dehydration process. Excessive consumption of dried fruit can cause weight gain."

2. Diet Soda

Diet soda is usually portrayed as a calorie-free alternative to regular soda, and they may seem like a guilt-free indulgence. However, research suggests that the artificial sweeteners and additives found in diet soda can disrupt gut health and contribute to belly fat. Despite containing zero calories, the artificial sweeteners in diet soda have been linked to alterations in gut bacteria and increased cravings for sugary foods, potentially leading to excess pounds on the scale.

Doebrich says that "drinking excessive amounts of diet soda" leads to "changes in the gut microbiome, which have negative health consequences" such as "gastrointestinal discomfort."

Murphy agrees and notes that artificial sweeteners in your favorite diet soda are "gut disruptors, which decrease the good bacteria in our guts and increase the bad ones," causing more gas and bloating.

3. Granola Bars

Despite its wholesome image, many store-bought granolas are filled with added sugars, unhealthy fats, and calorie-dense ingredients like nuts and dried fruits.

Nanavati states, "Often marketed as healthy snacks, granola bars can be calorie-dense due to added sugars, oils, and processed grains. Granola bars frequently contain concentrated forms of sugar like syrups and dried fruit, contributing to sugar overload and its associated gut health issues. Many granola bars use refined grains instead of whole grains, lacking fiber and promoting blood sugar spikes, potentially leading to weight gain and increased hunger."

4. Sweetened Yogurt

Sweetened yogurt, while often advertised as a healthy option, can sabotage efforts to reduce belly fat. Loaded with added sugars and artificial ingredients, these commercially-made yogurts can disrupt your gut health and cause bloating, inflammation, and weight gain around your waistline.

"Many store-bought yogurts have too much-added sugar, exceeding the recommended daily intake. Excess sugar promotes harmful gut bacteria growth, leading to inflammation, bloating, and digestion issues. Certain yogurts contain artificial sweeteners, which studies suggest could potentially disturb the composition of the gut microbiome and contribute to weight gain," says Nanavati.

As for gut health, she says "a lot of flavored yogurts fall short in providing enough fiber, which is crucial for maintaining a healthy gut and feeling full. Insufficient fiber intake can result in constipation and consuming more calories than needed."
