Cancer and diet
Cancer is a disease that can be caused by a variety of different factors. However, diet is thought to play a role in the development of cancer. Certain dietary habits may increase the risk of developing cancer, while others may help to protect against it.
There are a number of different theories about how diet affects cancer risk. Some believe that certain foods may contain substances that can damage DNA, leading to the development of cancer. Others believe that the way in which we process food can impact our risk. For example, eating lots of processed meat has been linked to an increased risk of stomach cancer.
There are a number of different dietary factors that have been linked to an increased risk of developing cancer. These include:
- - Eating a lot of processed meat
- - Eating a lot of red meat
- - Eating a lot of saturated fat
- - Eating a lot of refined carbohydrates
- - Drinking a lot of alcohol
There are also a number of dietary factors that have been linked to a reduced risk of developing cancer. These include:
- - Eating plenty of fruits and vegetables
- - Eating plenty of fibre
- - Eating plenty of antioxidants
- - Avoiding sugar
- - Limiting alcohol intake
It’s important to remember that diet is just one of many lifestyle factors that can affect cancer risk. Other important factors include smoking, sun exposure and obesity.
If you’re concerned about your cancer risk, it’s important to speak to a doctor or dietitian. They will be able to give you tailored advice based on your individual circumstances.
Appetite Loss and Cancer Treatment
As the American Cancer Society notes, Cancer treatment can affect your appetite, eating habits, and weight. Whether you have lost weight, gained weight, or are at a stable weight, it is important to make sure you are getting the nutrients your body needs. A registered dietitian nutritionist (RDN) can help you create a personalized nutrition plan.
Cancer and cancer treatment can affect your appetite in many different ways. You may lose your appetite completely, or you may find that certain foods smell or taste bad. Some people feel full after only a few bites, or they may have trouble swallowing. You may also have food aversions, which means you have strong feelings or reactions to certain foods.
Cancer treatments, such as surgery, radiation therapy, and chemotherapy, can also lead to changes in your eating habits. For example, surgery may make it hard to eat or drink for a while. Or, you may have a feeding tube or IV. Radiation therapy to the head and neck area can make it hard to swallow. Chemotherapy can cause mouth sores, making it hard to eat.
All of these changes can lead to weight loss. But, cancer and cancer treatment can also cause weight gain. For example, some chemotherapy drugs and steroids used to treat cancer can cause weight gain. Side effects such as nausea, vomiting, and constipation can also lead to weight gain.
