the Link Between Dairy Products and Ulcerative Colitis

Whey protein

Hello: My ulcerative colitis has relapsed, and I read in the patient handbook that in addition to a low-residue diet, I should avoid milk and all dairy products.
I would like to ask about the relationship between milk, dairy products, and ulcerative colitis, and why I should not consume milk and dairy products.
Additionally, I want to supplement the beneficial bacteria in my gut, so I am considering buying a yogurt maker to make yogurt using soy milk.
However, I am concerned that the fermentation cultures may contain dairy ingredients, so I seek your assistance.
The store informed me that the fermentation culture contains: 8 types of active lactic acid bacteria powder and whey protein concentrate.
I am unsure if these ingredients are safe for me to consume.
Also, I would like to ask if whey protein is considered a dairy product.
If so, is whey protein powder available on the market classified as a dairy product? Thank you for your help; I appreciate it.

Dr. Xie Peiru reply Nutrition

Dear Ms.
Hsiao,
Ulcerative colitis is a challenging condition, and I commend you for your efforts.
In response to your questions:
1.
Milk and dairy products are high-fiber foods, and it is recommended that you avoid them.
2.
Is whey protein considered a dairy product? Whey protein is the liquid that separates from the curds during cheese production, so it is indeed a component of milk amino acids.
3.
The strains of lactic acid bacteria, like any other strains, can produce fibrous components.
Given your condition of colitis, it is advisable to avoid them.
Finally, I recommend that you have your situation evaluated by a physician and discuss your dietary choices with them.
Wishing you a speedy recovery!
Sincerely,
Chihshan Hospital

More Info

Understanding the relationship between dairy products and ulcerative colitis (UC) is a complex topic that involves individual dietary responses and the underlying mechanisms of the disease. Ulcerative colitis is a chronic inflammatory bowel disease (IBD) characterized by inflammation of the colon and rectum, leading to symptoms such as diarrhea, abdominal pain, and rectal bleeding.
Many patients with UC report that certain foods, including dairy products, can exacerbate their symptoms. This is often attributed to lactose intolerance, which is common in individuals with IBD. Lactose intolerance occurs when the body lacks sufficient lactase, the enzyme needed to digest lactose, the sugar found in milk and dairy products. When lactose is not properly digested, it can lead to gas, bloating, diarrhea, and abdominal pain, which can worsen the symptoms of UC.

In addition to lactose intolerance, some studies suggest that dairy products may promote inflammation in certain individuals. The proteins found in dairy, such as casein and whey, can trigger immune responses in some people, potentially exacerbating the inflammatory processes associated with ulcerative colitis. Furthermore, the fat content in full-fat dairy products may also contribute to inflammation, although this can vary from person to person.

Regarding your concern about yogurt made from soy milk, it is essential to consider the ingredients of the starter culture used for fermentation. The presence of whey protein concentrate in the starter culture indicates that it contains dairy components. If you are avoiding dairy due to your UC, it would be prudent to seek out yogurt cultures that are explicitly labeled as dairy-free or vegan. Many stores offer probiotic cultures that are suitable for making yogurt from non-dairy sources, such as soy, almond, or coconut milk.

As for whey protein, it is derived from milk and is considered a dairy product. Therefore, whey protein powder would fall under the category of dairy products. If you are managing ulcerative colitis and have been advised to avoid dairy, it would be best to refrain from using whey protein and instead look for plant-based protein alternatives.

In summary, the relationship between dairy products and ulcerative colitis can vary significantly among individuals. While some may tolerate dairy without issues, others may find that it exacerbates their symptoms. It is advisable to keep a food diary to track your symptoms in relation to your diet, which can help you identify specific triggers. Consulting with a healthcare professional or a registered dietitian who specializes in gastrointestinal disorders can provide personalized dietary recommendations tailored to your condition. They can help you navigate food choices, including the use of probiotics and alternative protein sources, to support your health while managing ulcerative colitis.
