Nutrition plays a crucial role in treatment, managing side effects, and overall quality of life. However, there is a lot of inconsistent and misleading information online—some of which may even harm health and worsen conditions. That’s why it’s important to have evidence-backed, high-quality information about nutrition.

We will be sharing more articles on nutrition at different stages of the cancer journey. This article offers practical tips for caregivers on preparing nutritious meals after a loved one’s first chemotherapy. It covers key considerations, dietary needs, and simple ways to provide support during recovery.

1. Get a Referral to a Registered Dietitian Early

📞📋 Ask the doctor to refer your loved one to a registered dietitian who specializes in cancer care. Nutrition plays a critical role throughout treatment—sudden weight loss and malnutrition can put patients at risk, sometimes even forcing them to pause treatment if their body is too weak to tolerate it.

💪 Even with your best efforts to help them maintain strength, weight and muscle loss can still happen. A professional dietitian can create a personalized plan to help them get back on track more effectively. It’s best to have one available when needed.

⏳Since referrals can take time, it’s best to request one early to avoid delays in care. If no dietitians are available within the cancer care system your loved one is receiving treatment from, you can ask their primary care doctor for a referral.

2. Prepare Food Safely to Avoid Infections

Cancer patients undergoing chemotherapy have weakened immune systems because treatment reduces white blood cell counts, making it harder to fight infections. This increases their risk of infections, including foodborne illnesses. To minimize risk, be extra cautious when selecting and preparing food:

✔ Keep foods at safe temperatures.

✔ Wash raw vegetables and fruits thoroughly.

✔ Use separate utensils, plates, and cutting boards for meats and produce.

✔ Avoid raw or undercooked meat, poultry, seafood, eggs or sprouts

3. Focus on Nutrient-Rich Foods

Cancer patients often need more protein and calories than those without cancer due to increased energy demands for treatment and recovery. Cancer and its treatments, such as chemotherapy, can cause loss of appetite, nausea, vomiting, and digestive issues, reducing food intake and hindering nutrient absorption. This raises the risk of weight loss and malnutrition, which can weaken the immune system, lower treatment tolerance, and negatively affect recovery and quality of life.

Protein is essential

Protein is essential for maintaining strength, healing, and recovery during cancer treatment. Including high-quality protein sources in meals supports muscle mass and overall health. Additionally, healthy carbohydrates from fruits, whole grains, and vegetables provide vital nutrients and fiber to sustain energy levels.

Fruits

Fruits such as bananas, berries, oranges, pears, and apples are great sources of vitamins and minerals that help boost the immune system. Some, like berries and apples, also have anti-inflammatory properties.

Ginger and Mediterranean diet

Some research suggests that ginger and the Mediterranean diet may help reduce nausea caused by chemotherapy. However, this doesn’t mean it will work for everyone—some individuals may have allergies or become sensitive to certain smells, which could make nausea worse.It's important to be aware of this option, but always tailor it to your loved one’s specific needs and preferences.

Staying hydrated

Staying hydrated is essential for managing side effects after treatment. Encourage drinking enough water and avoiding high-sodium meals.

Foods to avoid

Some patients may experience a sore throat after treatment, so it’s best to avoid spicy or acidic foods. If they have difficulty swallowing, avoid hard foods like chips or crackers and opt for soft foods or soups instead. Additionally, some patients may feel cold sensitivity—drinking cold water might feel like swallowing glass—so it’s best to avoid cold drinks and foods.

But when it comes to specific nutritional needs—such as how much protein, carbohydrates, or other nutrients your loved one requires—it’s best to consult a registered dietitian for a personalized meal plan based on their condition.

4. Be Cautious with Supplements

While supplements can be helpful, some may interfere with chemotherapy drugs and cause harm. Always check with your doctor before taking any supplements.

5. Eat Small, Frequent Meals Instead of Large Ones

🍛 After chemotherapy, nausea and loss of appetite are common. Forcing large meals isn’t the solution—but eating small, frequent meals can help. Research suggests that smaller portions may ease nausea and improve intake. 

🥣 Try preparing nutrient-rich, easy-to-digest meals or snacks, such as mashed sweet potatoes with grilled salmon, oatmeal with nut butter and soft fruits, or chicken or tofu with steamed rice and vegetables. These are just examples—you can tailor meals to your loved one’s specific condition, preferences, and dietary needs.

6. Different Treatments Have Different Nutritional Needs

Different cancer treatments come with different side effects, which can impact nutritional needs. For example, hormone therapy may cause weight gain and raise blood sugar levels, making it important to watch sugar intake.

Consulting a dietitian specializing in cancer care can help create a personalized nutrition plan to support your loved one’s health and treatment journey.

7. Caregiving Isn’t Easy—You Are Not Alone

Food is one of life’s greatest joys, but for cancer patients and their caregivers, mealtimes can become stressful instead of comforting.   Patients may struggle to eat or keep food down, making every bite feel like a battle. For caregivers, watching a loved one struggle and feeling helpless can be just as painful.

You may try everything to encourage them to eat, only to face frustration and worry. If you’re experiencing this, you’re not alone. Many caregivers have shared similar struggles:

“I’m starting to feel defeated. Because I’m like if you lose any more weight, you know, and I’m so afraid for this, it’s like—he is doing the best he can. He’s eating. He is eating. He’s just not eating as much. He went from eating a whole bowl of oatmeal, to a half a bowl, to now it’s a couple of bites…And in his mind, he’s eating a lot, he’s doing great. And I’m like “Really?”. . . you’re losing weight. I’m worried. I’m starting to worry. I just don’t know what else to do.”

“I just have to force it on him, and remind him. I tell him “it’s breakfast”—because we’re on a schedule—“It’s lunch, it’s dinner.” I became more forceful with him. Before I was—you do what you gotta do. But now I’m the one that’s more forceful. And, I try to make things a bit more seasoned, than I would normally do, because hopefully he’d be able to taste it. And then he’s throwing it out because he doesn’t want to eat it all. So now I’m starting to feel bad about that. Now you’re wasting food. I don’t know . . . I just keep asking for tips and hints on the internet, the doctors, somebody give me some tips. Because I don’t know what else to do, because he’s not eating.”

“It started out with everything tasted like metal for a couple weeks. And now, since last week, he has zero taste. Unless it’s super strong, like if he eats something that has citric acid, he’ll taste a twinge of it or if it’s super spicy. Other than that, he has zero taste. So, I try my best—‘You got to try to imagine it, try to imagine it. Eat with your eyes.’ But that doesn’t work, of course. So I just say—‘Just let it go down. When your stomach feels full, stop.’ . But it’s like—trying to get him to want to eat. And he says ‘Well what’s the point? I can’t taste it.’ And I say ‘Because you have to eat.’ So, because he doesn’t even want to eat now, that’s the problem I’m dealing with now. But now, they’re threatening him with– if you lose any more weight, you’re going to get a feeding tube. So now it’s like ‘Give me potatoes!”

It's a new journey of exploration with food, and you and your loved one may need to navigate it together.
