Introduction:

Oncology nutrition is important in cancer care, proper nutrition plays a critical role in managing cancer treatment-related side effects, improving treatment outcomes, and enhancing the quality of life for cancer patients. In this blog, we will delve into various aspects of oncology nutrition, including the importance of a balanced diet, strategies to manage the side effects of cancer treatment through nutrition, and the role of specific nutrients in cancer prevention and treatment. We will also discuss the importance of working with a certified Nutritionist to develop an individualised nutrition plan based on the unique needs of each patient. By the end of this blog, you will have a better understanding of how proper nutrition can help manage cancer treatment-related symptoms and improve overall health outcomes in cancer patients. So, let’s get started!

 

Factors affecting the nutrition aspect in cancer patients:

  1. Cancer Treatment: Oncology nutrition is influenced by cancer treatments such as chemotherapy, radiation therapy, and surgery. These treatments can cause various side effects such as loss of appetite, taste changes, nausea, and vomiting that can lead to malnutrition.
  2. Cancer Type: The type and stage of cancer can also affect oncology nutrition. Certain cancers such as head and neck cancers can affect a patient’s ability to swallow, while digestive system cancers can impact nutrient absorption.
  3. Psychological and Emotional Factors: Cancer patients may experience anxiety, depression, and stress that can affect their appetite and nutrition. This can also impact their adherence to recommended diets.
  4. Pre-existing Nutritional Status: Patients who are malnourished before a cancer diagnosis is at higher risk of developing nutrition-related complications during cancer treatment.
  5. Lifestyle Factors: Unhealthy lifestyle habits such as smoking, alcohol consumption, and a diet high in ultra processed foods. These foods undergo ultra processing techniques which may increase the risk of developing cancer. And lack of fruits, vegetables and whole grains in the diet over a long period of time leads to various health conditions. 

 

Symptoms of cancer patients:

  1. Loss of Appetite: Patients may experience a reduced desire to eat or difficulty consuming adequate amounts of food.
  2. Changes in Taste and Smell: Cancer treatments can cause taste and smell changes, leading to aversions and disinterest in certain foods.
  3. Nausea and Vomiting: Patients may experience these symptoms due to cancer treatments, leading to decreased appetite and poor nutritional intake.
  4. Digestive Problems: Cancer treatments can cause diarrhoea, constipation, and other digestive problems, leading to poor nutrient absorption.
  5. Weight Loss: Unintended weight loss can occur due to poor appetite and malabsorption of nutrients.
  6. Fatigue: Malnutrition can cause fatigue and weakness, leading to decreased physical activity levels.
  7. Cognitive Changes: Malnutrition can affect cognitive function, including memory, attention, and concentration.

 

 

Nutrition intervention for cancer patients:

  1. Dietary Modifications: Patients may require specific dietary modifications to manage symptoms and optimise nutritional intake. This may include increasing protein and calorie intake, consuming small, frequent meals, and avoiding foods that trigger nausea and vomiting.
  2. Nutritional Supplements: Supplements such as protein powders, and vitamins and minerals may be recommended to address nutrient deficiencies and improve overall nutrition status.
  3. Enteral and Parenteral Nutrition: In cases where patients cannot consume adequate amounts of food orally, enteral and parenteral nutrition may be recommended. Enteral nutrition involves feeding through a tube, while parenteral nutrition involves intravenous feeding.
  4. Exercise: Exercise and physical activity may be recommended to improve appetite and overall health

 

Common misconception about Oncology Nutrition:

Myth: Sugar feeds cancer cells.

  1. Fact: There is no conclusive evidence to suggest that sugar intake directly promotes cancer growth. In fact, many studies have failed to find a significant link between sugar consumption and cancer risk. Nonetheless, maintaining a balanced and healthy diet with a focus on whole foods can help reduce the risk of cancer and improve overall health.

Myth: A vegetarian diet is better for cancer patients.

  1. Fact: Even though a plant-based diet can have health advantages and lower the risk of some cancers, it’s not always superior to a diet that has animal products. For cancer patients, it’s important to have a customised nutrition plan that considers their specific needs and medical issues.

Myth: Cancer patients should avoid all fats.

  1. Fact: Fats are an essential component of a balanced diet and play a crucial role in providing energy and essential nutrients to the body. Many types of fats, such as omega-3 fatty acids found in fish, nuts, and seeds, have been shown to have anti-inflammatory effects and may be beneficial for cancer patients. However, it is important to consume fats in moderation and choose healthy sources of fats such as avocados, olive oil, and nuts.

Myth: Supplements are always safe and effective.

  1. Fact: While supplements can provide important vitamins and minerals, some may interact with cancer treatments or cause adverse effects. For example, some supplements can interfere with chemotherapy drugs or radiation therapy, potentially reducing their effectiveness. Additionally, some supplements may cause harmful side effects, especially when taken in large doses. Patients should always consult with their healthcare provider before taking any supplements, even those marketed as natural or safe.

Myth: Cancer patients should avoid all processed foods.

  1. Fact: Processed foods can be nutrient-dense and provide important nutrients for cancer patients. Canned and frozen fruits and vegetables are convenient, affordable and a great source of nutrients. Look for processed foods with low sodium, added sugars, and saturated fats by reading the labels.

 

Facts about Oncology Nutrition:

Fact: Adequate nutrition is crucial for cancer patients.

  1. Proper nutrition is vital for cancer patients to support their overall health and well-being during treatment. Patients who are well-nourished may have better treatment outcomes, improved immune function, and a better quality of life.

Fact: Protein is important for cancer patients.

  1. Protein is a crucial nutrient for cancer patients as it helps to maintain muscle mass, repair tissue, and support the immune system. Eating protein-rich foods such as lean meats, fish, and eggs can help ensure patients are getting enough protein to support their recovery.

Fact: Hydration is important for cancer patients.

  1. Cancer treatments can cause side effects such as nausea and vomiting, which can lead to dehydration. Staying hydrated can help manage these side effects and prevent dehydration, which can be a serious concern for cancer patients. Drinking enough fluids is essential for supporting the body’s functions and overall health.

Fact: Nutrition needs may vary depending on the type and stage of cancer and the type of treatment.

  1. Each patient’s nutritional needs may vary based on their type and stage of cancer and the type of treatment they are receiving. Developing individualised nutrition plans can help patients manage side effects and support recovery after treatment.

Fact: Nutritional counselling is an important part of cancer care.

  1. Nutritional counselling can help patients make healthy choices, manage treatment side effects, and support their overall health and well-being during and after cancer treatment.

Conclusion:

In summary, Oncology Nutrition is crucial in managing symptoms and improving treatment outcomes for cancer patients. Individualised nutrition plans developed with registered dietitians can help address the specific nutritional needs of patients. By prioritising Oncology Nutrition, healthcare providers can improve the overall quality of life for cancer patients.

If you are someone looking for a nutritionist’s guidance and find yourself encountering terms you don’t understand, you have come to the right place.

 

The nutritionist might tell you many things in Greek and Latin and you might be confused. It is true that some of our clients feel the same way when we suggest they take supplements to combat deficiencies. When we explain to them that they aren’t allergic but intolerant, they seem to get a tad confused. It is also possible that some people have a misconception about processed foods. 

 

By understanding the most commonly used terminologies and their differences, you will be better able to understand what you eat and what your nutritionist recommends.

 

  • NUTRIENT VS FOOD 

 

Most of us confuse the terms nutrient and nutrition. The term nutrition encompasses the term nutrient. 

 

Nutrients – are substances that are required for the nourishment of organisms while 

Nutrition –  is the entire process by which organisms obtain energy and nutrients from food.

 

We might also think food and nutrients are the same.

 

Food is the source of energy that helps our body to function properly and stay alive.

 

Nutrients are a part of food, which are used and metabolized by our body cells to provide energy.

 

Example: Fruit is your food and the vitamins and minerals in it are the nutrients.

 

Recipe – Smoothie is the food, the carbs, vitamins, minerals, protein, and fat we get from the ingredients are the nutrients.


  •  ALLERGY VS INTOLERANCE

 

It is possible to experience adverse reactions after eating certain foods. 

 

These reactions can be categorized as immunologic (allergic) and non-immunologic (intolerance).

 

Many people mistake food intolerance for allergy as one of its symptoms is allergy-like reactions.

 

  Allergy: 

  • Allergies occur when the body’s immune system responds or overreacts to a particular type of protein. 
  • This protein is usually from foods, pollens, house dust, animal hair, or moulds and they are called allergens. 
  • During allergy, our body produces antibodies to defend substances that are usually harmless.

 

Intolerance:

 

Food intolerances arise if the body is unable to digest a certain food. This impairment may be due to a lack of digestive enzymes or a sensitivity to certain chemicals.

 

Food intolerance refers to the body’s inability to digest certain chemicals in food due to lack of enzymes or sensitivity to the chemical.

 

  • These are chemical reactions that occur that are not immune responses.
  • This often happens when we can’t properly digest particular food or its components. 
  • Food intolerances are uniquely individualized. 

 

Food allergy is more severe and fatal than food intolerances.

 

Example for allergy: Peanut allergy or shellfish allergy – A person who is allergic to peanut or shellfish, and eats one of these could even die without medical assistance. 

Symptoms: can start with rashes, hives, and itching and can develop into fatal symptoms like dilation of blood vessels, drop in blood pressure, etc. 

 

Example of food intolerance: It mostly occurs from enzyme deficiency. 

Many people can be lactose intolerant – they won’t have the enzyme lactase which is necessary to digest lactose, the main sugar in milk.

Symptoms: nausea, vomiting, diarrhea, headache, etc. 


  • PROCESSED VS ULTRA-PROCESSED

 

The newest trend buzzing around among people is “saying NO to processed food”.

But one must understand that food does not make it from the farm to the fork unprocessed.

Even the fruits that we eat require some processing before they reach our plates. 

Choosing minimally processed foods is probably a better option than ultra-processed foods.

 

Processing:  Processing is anything that alters the fundamental nature of agricultural produce, such as freezing, dicing, drying, etc.

  • The nutrients in these foods will still be intact. 

Example: The milk we drink daily requires processing such as pasteurization to extend its shelf life. 

 

Ultra processing: A technique that converts agricultural produce into an entirely different form is known as ultra processing. 

 

Highly processed foods, also known as ultra-processed foods, are relatively cheap, convenient, and tasty but contain a lot of refined carbohydrates, saturated fat, and salt. 

  • They could also be referred to as hyper-palatable foods. 

Example: Potato chips, bread, soft drinks, etc.

 

  • SUPPLEMENTS VS MEDICINE

 

DIETARY SUPPLEMENTS: A dietary supplement is a vitamin, mineral, herb, or nutrient that a person takes to treat or combat nutritional deficiencies, improve their overall well-being, or improve their overall wellness.

Dietary supplement labels may make certain health-related claims, but they are not intended to treat or cure any specific disease. Dietary supplements are generally safe to consume and cause no adverse reactions. 

 

MEDICINE: This is a preparation or substance used to treat a particular disease and ease symptoms. Several chemicals are mixed together in laboratories to produce medicines.

 

For example, fish oil that we consume to lower the cholesterol level is a supplement and the fever medication that we get only with a doctor’s prescription is medicine.

 

  • COD LIVER OIL VS FISH OIL 

 

COD LIVER OIL – as the name suggests, it’s derived from codfish livers.

The oils in these fish tend to build up in the liver, and they also contain high levels of vitamins A and D.

 

FISH OIL – Fish oil comes from the flesh of fatty fishes such as tuna, mackerel, and salmon. 

This results in higher concentrations of EPA and DHA.

Fish oil doesn’t contain Vitamin A or D.

 

However, cod liver oil often contains a lower concentration of omega 3’s when compared to omega 3 fish oil.


 

  •  SATURATED FAT VS TRANS FAT

 

SATURATED FATS: Saturated fat is solid at room temperature due to its chemical structure. 

Foods high in saturated fats tend to be high in cholesterol, hence consuming foods rich in saturated fats tends to cause more diseases. 

It has also been found that foods containing saturated fats are highly processed and contain more sugar and sodium which might have an effect on our body. 

Therefore, saturated fats should always be balanced with other types of fats such as MUFA and PUFA.

 

Example: butter, cream, cheese, coconut, etc.

 

TRANS FAT: Trans fat comes from industrial fat processing where saturated or unsaturated fats are processed by adding hydrogen ions to them. 

Trans fats are also solid at room temperature. 

The process of adding hydrogen ions is known as hydrogenation and they extend the shelf life of the product.

 

Example: margarine, shortenings, etc.

 

When we talk about nutrition, we often hear the following statements. We even hear some of these statements every day. But how true are they?

 

In this article, we will debunk 6 such statements:

 

  1. FLAX SEEDS ARE THE RICHEST SOURCE OF OMEGA-3 FATTY ACIDS. 

 

Our common perception is that flax seeds are rich in omega-3 fatty acids.

 

But in reality, they are a rich source of fiber, but not the best source of omega-3.

The omega-3 fatty acid found in flax seeds is ALA (Alpha-linolenic acid), which our bodies cannot convert to EPA/DHA.

 

Therefore, the most ideal choice is to consume EPA/DHA-containing foods such as fatty fish, salmon, tuna, etc.

 

  1. NOT EVERYONE NEEDS A GLUTEN-FREE DIET

 

Gluten is a type of protein found in wheat, maida, and rye which is responsible for the elasticity of these flours. 

 

So, WHO NEEDS A GLUTEN-FREE DIET? 

 

Individuals with celiac disease or individuals with gluten sensitivity or those who can’t tolerate even small amounts of the protein gluten should go gluten-free. 

 

If you are not gluten sensitive or have celiac disease, eliminating gluten from your diet can cause nutritional deficiencies. 

 

  1. EGGS ARE HEALTHY AND GOOD FOR CHOLESTEROL

 

Eggs are an economical and easily available source of high-quality protein which is a key source of many essential nutrients. 

 

Cholesterol is a waxy substance that is produced majorly in our body, forms an important part of our cells and is very important for the proper functioning of our body. 

While cholesterol is important for body functions, high amounts can lead to heart problems. 

But however not all cholesterol is bad, the cholesterol that comes from the foods you eat has a minimal impact because the body naturally regulates the amount of cholesterol that circulates in the blood.

 

WHAT HAPPENS IN AN EGG?

 

For many years now, we all have been thinking that egg yolk is full of saturated fat. But, the truth is that the major fat portion in eggs comes from MUFA and PUFA. 

Saturated fats when consumed along with MUFA and PUFA don’t show to have much effect on cholesterol.  

Also, if you are still not convinced and are skeptical about consuming whole eggs daily, remember that consuming saturated fats along with lots of ultra-processed foods/refined carbohydrates is unhealthy. 

Instead include eggs as a part of your healthy diet along with fruits, vegetables, and whole grains. 

 

  1. LATE-NIGHT EATING WILL MAKE YOU GAIN WEIGHT.

 

Many people think eating late at night will make them fat but the truth is it doesn’t. 

According to science, a calorie is a calorie taken regardless of the time. 

What causes weight gain is the type of food you eat and the number of calories you eat. 

Most studies suggest that nighttime eaters mostly make poor choices of food. 

Studies show that most people who eat late at night binge eat to keep them awake, for this they rely on hyper-palatable foods that are high in sugar and fats that have low satiety value and make them eat more. 

The second most important point is that the calories that go in from the hyper-palatable foods must be burned out, if not definitely it will make them gain weight. 

VERDICT – Eating late at night is not bad but the type of food we eat matters the most and the calories we eat must be within the limits. 

 

  1. IS IT OKAY TO SKIP YOUR BREAKFAST?

 

For most of our lives, breakfast has often been dubbed “BREAKING THE FAST” and is considered one of the most important meals of the day.

 

They say skipping breakfast might lead you to overeat later in the day.

 

But, this is not true.

 

Also, it may not cause you to eat less either. It definitely depends on the individual. 

 

If you are taking appropriate amounts of calories and nutrients throughout the day, skipping breakfast won’t make much difference. 

 

  1. A DETOX DIET IS IMPORTANT

 

A detox diet – is a more popular diet trend that claims to detox/ clean our body and eliminates harmful toxins from our body. 

A typical detox diet involves a period of fasting followed by a diet that includes only fruits, vegetables, fruit juices, and water. Sometimes it might also include herbs, teas, and enema. 

 

THE TRUTH – our body doesn’t need any detox program or diet, it’s naturally designed to detox itself. Our organs such as the liver, kidney, and lungs are detoxification machines that are naturally designed to get rid of the toxins from our body. 

That means maintaining a healthy diet is important in order to maintain the proper functioning of these organs. 

 

THE CON – The detox diets can also be dangerous since they include only a particular type of food group and avoid most of them and can cause nutritional deficiencies, electrolyte imbalances, and other problems.
