Cancer treatments such as chemotherapy, radiation therapy, and hormone therapy can cause a variety of side effects, including constipation, fatigue, and weight gain. This can result in a reduced appetite, making it difficult for cancer patients to get the calories and nutrients they need to stay strong. Maintaining a healthy weight and good nutrition through a balanced diet can help to reduce the risk of cancer and other chronic diseases, as well as manage the side effects of treatment. Thus, diet plays a crucial role in helping cancer patients maintain their health and quality of life during treatment.

What You'll Learn
Cancer treatment side effects like nausea and vomiting
Cancer and its treatment can affect every aspect of a person's health, including their appetite and diet. Chemotherapy and radiation therapy can cause a variety of side effects, including nausea and vomiting.
Nausea and vomiting are very common among chemotherapy patients, with up to 70% of patients experiencing these symptoms despite taking anti-nausea medications. However, dietary adjustments can help manage these side effects. Eating small meals frequently can help reduce nausea and improve nutrition compared to eating larger meals less often. It is also recommended to avoid high-fat, greasy, or spicy foods, as well as those with strong smells. Instead, opt for dry foods like crackers or toast, and sip clear liquids like broths, sports drinks, and water throughout the day.
Food temperature is another important consideration for patients prone to nausea and vomiting. Eating most of your food at room temperature or cold can help reduce nausea, as hot food tends to emit stronger odors, which can be off-putting. Additionally, it is advised to avoid cooking areas and strongly scented products like perfumes and air fresheners to minimize exposure to triggering smells.
Some specific food and drink options that can help with nausea include:
- Ginger tea, ginger water, or ginger ale
- Apple juice, sherbet, or Jell-O
- Clear carbonated drinks, cranberry or grape juice, and plain gelatin
- Sour foods like sour candy, pickles, lemons, or limes
It is important to note that everyone's reaction to treatment is unique, and side effects may vary in severity or may not occur at all. Consulting with a healthcare provider before treatment begins can help address concerns about potential side effects and develop a nutritional plan to manage them effectively.

How to maintain a healthy weight
Maintaining a healthy weight is important for cancer patients, as cancer treatment can lead to fluctuations in appetite and body weight. A healthy weight can help patients feel more energetic and reduce the chances of developing other health problems. Here are some ways to maintain a healthy weight:
Firstly, it is important to follow a nutritious eating pattern. This involves eating a balanced diet with lean proteins, fruits, vegetables, whole grains, and low-fat dairy. Cancer patients should focus on eating foods high in protein, healthy fats, whole grains, and vitamins and minerals. Plant-based proteins such as beans, legumes, nuts, and seeds are recommended as they offer high levels of vitamins and minerals. If eating animal proteins, it is best to choose lean options like chicken or fish. Cancer patients should also ensure they are staying hydrated by drinking plenty of liquids, especially water.
Secondly, physical activity is crucial. Regular moderate or vigorous physical activity can provide immediate and long-term health benefits. Walking is a good way to add more physical activity to one's lifestyle. For cancer patients, it is important to note that treatments such as chemotherapy and radiation therapy can cause fatigue, reducing the desire to be physically active. Therefore, patients should consult with their doctors to determine the appropriate level of physical activity during treatment.
Thirdly, getting optimal sleep and reducing stress are important factors in maintaining a healthy weight. Sleep and stress can affect weight, and cancer treatments may impact these areas. Finally, it is important to remember that maintaining a healthy weight is not just about diet and exercise; other factors such as genes, age, sex, lifestyle, and cultural habits also play a role. Consulting with a healthcare professional is always recommended before making any significant changes to one's diet or exercise routine.

The importance of nutrition before, during, and after treatment
Nutrition is an essential aspect of cancer treatment, recovery, and prevention. A healthy diet is crucial for the body to function optimally and is even more critical for those dealing with cancer. Before cancer treatment, it is beneficial to focus on healthy eating habits and ensure proper nutrition. This means consuming a balanced diet that includes lean proteins, fruits, vegetables, whole grains, and low-fat dairy. It is also advisable to consult a registered dietitian, who can provide guidance and create a nutrition care plan tailored to individual needs.
During cancer treatment, nutrition becomes even more critical as the body needs extra calories and protein to maintain strength and cope with the side effects of treatment. Cancer treatments such as chemotherapy and radiation therapy can lead to fluctuations in appetite and weight loss. To counteract this, it is important to eat nutrient-dense foods that provide sufficient calories and protein. This may include plant-based proteins, lean animal proteins, and healthy snacks throughout the day. Additionally, side effects such as nausea and vomiting can make it challenging to eat, so it is recommended to avoid high-fat, greasy, or spicy foods and opt for dry foods, clear liquids, and nutritional supplements if necessary.
After cancer treatment, proper nutrition remains vital to support recovery and maintain good health. It is important to gradually transition back to a healthier diet, rich in whole grains, fruits, and vegetables, while still ensuring adequate calorie and protein intake. Physical activity, when approved by a doctor, can also aid in maintaining muscle mass, strength, and overall health during this time.
Throughout the entire cancer journey, from diagnosis to treatment and recovery, nutrition plays a pivotal role in supporting the body and improving overall well-being. It is important to seek professional guidance from healthcare providers and registered dietitians to ensure optimal nutrition before, during, and after cancer treatment.
While there is no specific diet to cure cancer, adopting healthy eating habits and ensuring proper nutrition can help individuals with cancer maintain their strength, manage side effects, and improve their overall quality of life.

Recommended foods to eat
A healthy diet is extremely important for cancer patients, as the disease and its treatment can affect their eating and drinking habits in several ways, including loss of appetite, changes in taste or smell, and nausea and vomiting. A balanced diet can help cancer patients maintain a healthy weight, fight nausea, and maintain energy.
- Plant-based proteins: These include beans, legumes, nuts, and seeds. They offer high levels of vitamins and minerals.
- Lean animal proteins: Chicken, fish, and turkey are recommended. These provide essential amino acids and help maintain muscle during cancer treatment.
- Fruits and vegetables: Aim for at least 2.5 cups a day, including dark green and deep yellow veggies and citrus fruits like oranges and grapefruits. Wash all fruits and vegetables thoroughly, even prewashed produce.
- Whole grains: These provide fiber and essential nutrients. However, if experiencing diarrhea, cut back on high-fiber foods like whole grains.
- Healthy fats: Avocado, olive oil, cashews, and walnuts are good sources of healthy fats, which help reduce inflammation in the body.
- Cruciferous vegetables: Broccoli and cauliflower are recommended for their nutritional benefits.
- Stone fruits: Peaches, plums, and nectarines are healthy options.
- Greek yogurt: This can be used as a base for a high-protein smoothie with added fruits and vegetables.
- Clear liquids: When experiencing nausea or vomiting, sip on broths, sports drinks, and water.
- Lukewarm meals: When dealing with mouth or throat problems, eat meals that are neither hot nor cold.
- Soft foods: For sores, pain, or trouble swallowing, opt for soft foods and use a straw for soups or drinks.
It is important to work with a registered dietitian to develop a personalized nutrition plan that considers the patient's unique health concerns, nutritional status, age, and any pre-existing conditions.

Foods to avoid
A healthy diet is crucial for cancer patients, as it can help them maintain their weight, energy levels, and overall health. However, there are certain foods that cancer patients should avoid to ensure they are getting the proper nutrition and to reduce the risk of foodborne illnesses. Here are some foods that cancer patients should typically avoid:
Highly Refined and Processed Foods: These foods are often stripped of their natural nutrients and can be high in unhealthy fats, sugars, and salt. Examples include sugary drinks, candy, white bread, and heavily processed snacks like chips and cookies.
Fried and Hydrogenated Oil-Rich Foods: Fried foods and those containing large amounts of hydrogenated oils should be limited. Hydrogenated oils are often used in processed foods and can increase inflammation in the body. Fried foods can also be hard to digest and may contribute to weight gain.
Foods That Increase the Risk of Foodborne Illness: Cancer patients often have compromised immune systems due to treatments like chemotherapy and radiation therapy. Therefore, it is essential to avoid foods that carry a high risk of foodborne illnesses, such as raw or undercooked meats, unpasteurized dairy products, raw shellfish, and raw egg-containing dishes.
Foods That Interfere with Medication Absorption: Certain foods can interfere with the absorption of medications or supplements that the patient is taking. For example, cancer patients taking thyroid medication should avoid soy products and large amounts of fibre, as they can hinder the absorption of thyroid hormones. It is important to consult with a healthcare professional or dietitian to understand any specific food restrictions related to medication.
High-Sugar and Simple Carbohydrate Foods: Cancer treatments can lead to fluctuations in blood sugar levels, so it is essential to avoid sugary foods and simple carbohydrates that can cause rapid spikes and crashes in blood sugar. This includes sweets, sugary drinks, white bread, and pastries. Instead, cancer patients should focus on complex carbohydrates like whole grains, which provide a more sustained release of energy.
It is important to note that the specific dietary needs of a cancer patient may vary depending on the type of cancer, the treatment plan, and individual factors. Consulting with a registered dietitian or nutritionist specializing in oncology can help cancer patients develop a personalized diet plan that ensures they are getting the proper nutrition to support their health and well-being during treatment.
