A low-microbial diet focuses on consuming well-cooked foods to help eliminate all potentially harmful pathogen-containing foods from the diet. The purpose of the diet is to minimize the introduction of infectious germs into the digestive system. Following a low-microbial diet should be done under the supervision of medical professionals to help ensure you are meeting your body's nutrition needs.
Who
A low-microbial diet is often recommended for those who are undergoing high doses of chemotherapy, radiation or bone marrow transplants. These treatments all weaken the immune system making it harder for the body to fight off even the smallest germs and infections. Because food and food handlers can be sources of infectious germs, it is important to monitor which foods are provided and how they are prepared on a low-microbial diet.
Duration
The diet should be followed at all times while receiving chemotherapy or radiation treatments. Once treatments are completed, it is recommended that a low-microbial diet be continued for at least two to three months. This allows the body and its immune system time to become stronger and more able to fight off potential pathogens. Discuss all dietary concerns with a health care professional. Avoid resuming a regular diet until instructed to do so by your doctor or dietitian.
Foods to Avoid
Many foods are avoided on a low-microbial diet making it difficult to follow a balanced diet that meets your nutrition needs. Foods that should be avoided on a low-microbial diet include, unpasteurized milk and dairy products, cheese with mold or vegetables within, deli meats and cheeses, undercooked meats and fish, cured, smoked or pickled foods, soft cooked eggs, unwashed fruits and raw vegetables, roasted nuts, vegetable sprouts, well water, fresh salad dressings, raw honey, yeast and herbal supplements. Discuss your diet with a dietitian to help make sure you are meeting your daily nutrition needs.
Considerations
It is important to consider many factors before consuming certain foods while on a low-microbial diet. Many foods that are allowed on a low-microbial diet still have the potential to grow molds and other bacteria. Discard all foods with visible mold or foods that have been refrigerated for more than one week after eating, such as leftovers. Also, be mindful of expiration dates and promptly throw away any foods that have expired. When shopping, avoid buying any foods with dented, cracked, swollen or open packaging. Store all foods properly to help prevent bacteria growth. Lastly, be sure to clean your hands, work surfaces and all utensils prior to eating or prepping foods.
