Milk, a staple in many diets, has long been praised for its nutritional benefits, particularly its calcium content and role in bone health. However, not all types of milk may be equally friendly to your gut microbiome. While milk is a valuable source of essential nutrients, some varieties may pose challenges to gut health. Certain processed or flavored milks can contain added sugars and artificial ingredients, potentially disrupting the delicate balance of your gut microbiome.
We spoke with Dr. Harsh Sheth, a bariatric and GI laparoscopic surgeon, to learn about two types of milk to stay away from because they negatively impact your gut microbiome, plus healthier alternatives. Dr. Sheth revealed that regular cow’s milk and sugary flavored milk are the ones to minimize. Read on to learn more.
Regular Cow's Milk
Regular cow's milk, while rich in essential nutrients like calcium and vitamin D, can potentially have negative effects on the gut microbiome for certain individuals. Some people may experience lactose intolerance, which Dr. Sheth elaborates on.
"Regular cow's milk poses a risk to those with lactose intolerance, potentially disturbing the gut microbiome balance. Ingestion of lactose by intolerant individuals can lead to symptoms like bloating and diarrhea, indicating a disruption in the gut environment," he says.
He also sheds light on the hormonal disruption aspect of this type of milk. "Milk from cows treated with growth hormones may contain residues that affect the gut flora balance when consumed." He adds on that "traces of antibiotics in non-organic milk risk contributing to the development of antibiotic-resistant bacteria strains in the human gut."
Sugary Flavored Milk
Sugary flavored milk, often found in various chocolate or fruit-flavored varieties, can have detrimental effects on the gut microbiome. These flavored options typically contain added sugars that may disrupt the delicate balance of gut bacteria.
"Sugary flavored milk can accelerate the growth of undesirable bacteria in the gut, upsetting the microbiome equilibrium. Excessive sugar consumption through flavored milk is linked to conditions such as obesity, which has ramifications for gut health," Dr. Sheth reveals.
Healthier Alternatives
Nevertheless, in recent times, numerous healthier alternatives are available, providing you with options to integrate a more gut-friendly choice for milk.
One type of healthier alternative is lactose-free milk."Lactose-free milk offers a similar nutritional profile to regular milk without the digestive unrest commonly experienced by those with lactose intolerance. This alternative does not trigger the aforementioned lactose-induced imbalances in the gut microbiome," Dr. Sheth says.
Another option you can try is plant-based milks. "Almond, soy, and oat milk provide various nutrients and phytochemical compounds that can support a healthy gut microbiome. For those preferring plant-based milk, choosing varieties without added sugars is important to avoid disrupting the gut bacteria balance," he shares.
Finally, fermented milk products are another great alternative as well. "Fermented milk products like kefir contain probiotics that actively support the health and diversity of the gut microbiome. Kefir may also be better tolerated by individuals with mild lactose sensitivity, as fermentation reduces the lactose content."
