4 min read

According to the American Cancer Society, certain dietary adjustments can help manage chemotherapy side effects, and yogurt is often a recommended food. Selecting the right yogurt can provide essential protein, calcium, and probiotics, but it is crucial to know what yogurt can you have on chemo to ensure food safety and comfort.

Quick Summary

This guide provides an overview of safe and nutritious yogurt options for patients undergoing chemotherapy. It details which types to choose, like pasteurized Greek yogurt, and which to avoid, including unpasteurized varieties and certain probiotic-heavy products, to help manage common side effects like taste changes, sore mouth, and digestive issues.

Key Points

Pasteurization is key: Always choose pasteurized yogurt to avoid the risk of foodborne illness, which is a major concern for immunocompromised patients during chemo.
Prioritize protein: Opt for high-protein yogurts like Greek or Icelandic varieties to help combat treatment-related fatigue and maintain muscle mass.
Soothing texture: The soft, creamy texture and cool temperature of yogurt make it ideal for soothing a sore mouth, throat, or managing nausea.
Manage side effects: Yogurt can be customized to address taste changes by adding sweeteners or pureed fruit, or by using specific types for lactose intolerance.
Avoid unpasteurized and high-risk probiotics: Unless specifically cleared by your oncologist, avoid unpasteurized dairy and certain probiotic-heavy products during periods of low immunity.
Consult your healthcare team: Always discuss dietary changes and the use of probiotics with your doctor or a registered dietitian to ensure they are appropriate for your individual treatment plan.

Importance of Yogurt During Chemotherapy

During chemotherapy, patients often experience side effects that make eating difficult, such as nausea, taste changes, and a sore mouth. Yogurt is a great dietary option because it is soft, easy to swallow, and can be consumed cold to soothe a sore throat. Beyond its texture, yogurt offers crucial nutritional benefits that support the body during treatment. High-protein versions, like Greek or Icelandic yogurt, can help combat the fatigue and muscle loss associated with cancer treatment.

Moreover, some yogurts contain probiotics, which are beneficial bacteria that can aid in digestion, potentially alleviating constipation or diarrhea—common gastrointestinal side effects of chemotherapy. However, it is vital to select the right kind, as some probiotic-rich or unpasteurized products can pose a risk to patients with weakened immune systems. Always consult with your oncologist or registered dietitian before incorporating new foods or supplements into your diet.

Safest Yogurt Options for Chemo Patients

Pasteurized Dairy Yogurts

The most critical factor when choosing yogurt during chemotherapy is ensuring it is pasteurized. Pasteurization is a heat treatment that kills harmful bacteria, making the product safe for individuals with compromised immune systems. Always check the label for the word 'pasteurized' on milk, cheese, and yogurt products.

Greek and Icelandic Yogurt: These varieties are strained, giving them a thicker texture and higher protein content, making them an excellent choice for a substantial, easy-to-eat snack. The added protein helps maintain strength and support tissue repair.
Plain Yogurt: Unflavored, plain yogurt is a versatile option that can be customized with safe additions. It's especially useful for those with taste changes, as it can be sweetened with honey or mixed with pureed fruits to mask metallic tastes.
Full-Fat Yogurt: If weight loss is a concern, opt for full-fat, creamy yogurts. The extra calories can help maintain a healthy weight and provide more energy.

Non-Dairy Yogurt Alternatives

For patients with lactose intolerance or those who prefer plant-based options, certain non-dairy yogurts can also be suitable. Look for fortified versions to ensure you're still getting important vitamins and minerals.

Soy Yogurt: A good source of plant-based protein, soy yogurt is widely available and typically fortified.
Coconut Yogurt: For a creamy, rich texture, coconut yogurt can be a soothing choice, particularly when a patient experiences a sore mouth.

How to Manage Side Effects with Yogurt

Yogurt’s versatility allows it to help with various chemotherapy-related side effects:

Sore Mouth or Throat: The cool temperature and soft texture are soothing. Blend it into smoothies for easier swallowing or freeze it into popsicles for a refreshing treat.
Nausea: Eating small amounts of bland, cold yogurt can help manage nausea. Combining it with other mild foods, like bananas or oatmeal, can make it more tolerable.
Taste Changes: For those experiencing a metallic taste, adding sweet or tart flavors can help. Mix yogurt with fruit purees, honey, or maple syrup. Using plastic or bamboo utensils can also help minimize a metallic taste.
Constipation or Diarrhea: Yogurt with probiotics may help regulate bowel movements, but only if approved by your medical team. For constipation, consider adding fiber-rich ingredients like ground flaxseed or bran if cleared by your doctor.

Yogurts and Products to Avoid During Chemo

Food safety is a top priority for immunocompromised individuals. It is crucial to be aware of products that may contain harmful pathogens.

Unpasteurized Products: This includes any yogurt made with raw milk. Always read labels carefully to ensure the product has been pasteurized.
Certain Probiotic-Rich Foods: While probiotics can be beneficial, high-risk patients (especially those who are neutropenic) are often advised to avoid fermented foods with "live" cultures. Consult your oncologist before consuming any probiotic-containing foods or supplements.
Expired or Improperly Stored Yogurt: Adhere to all expiration dates and storage instructions to minimize the risk of foodborne illness.
