Some people refer to berries, fatty fish, walnuts, and other foods as cancer-fighting foods. No single food protects people against cancer, but some foods contain nutrients that may help reduce the risk as part of a balanced diet.
Consuming a varied diet that includes the items mentioned below may help keep a person healthy and reduce their risk of cancer.
It is worth noting that polyphenols, resveratrol, vitamin C, and other nutrients are present in many plant-based foods, so this list is not exclusive.
This article looks at some foods that may lower the risk of cancer. It also explains the science that supports these claims.

There may be some truth to the saying, “an apple a day keeps the doctor away.” Apples contain polyphenols that have promising anticancer properties.
Polyphenols are plant-based compounds that may help to prevent inflammation, cardiovascular disease, and infections.

One
This polyphenol inhibits a protein called glucose transporter 2 (GLUT2), which plays a role in advanced-stage cell growth in certain types of cancer.
Berries are rich in vitamins, minerals, and dietary fiber. Their antioxidant content may mean they have health benefits.

According to a
Cruciferous vegetables, such as broccoli, cauliflower, and kale, contain beneficial nutrients, including vitamin C, vitamin K, and manganese.
Cruciferous vegetables also contain sulforaphane, a plant compound with potential anticancer properties.

Other research shows that sulforaphane, in combination with genistein — a compound in soybeans — can significantly inhibit breast cancer tumor development and size. Sulforaphane also inhibits histone deacetylase, an enzyme with links to cancer development.
One review suggests
Carrots contain several essential nutrients, including vitamin K, vitamin A, and antioxidants. Carrots also contain high amounts of beta-carotene, which is responsible for the distinct orange color.
The results suggested that raw carrot consumption may reduce the risk of colorectal cancer by 17%. They also suggested raw carrots may protect against:

Fatty fish, including salmon, mackerel, and anchovies, are rich in essential nutrients, such as B vitamins, potassium, and omega-3 fatty acids.

According to the American Institute for Cancer Research, all nuts appear to have cancer-preventing properties, but scientists have studied walnuts more than other types.
Walnuts contain a substance called pedunculagin, which the body metabolizes into urolithins. Urolithins are compounds that bind to estrogen receptors and

Researchers tested tumor tissue samples removed during surgery and compared them with the original biopsy results. They found signs that genetic changes had taken place, which could suggest the suppression of cancerous cell growth.
Legumes, such as beans, peas, and lentils, are high in fiber, which may help lower the risk of some types of cancer.
For example, one
The study results indicated that people with diets high in bean fiber were 20% less likely to develop breast cancer than those who did not meet their daily fiber intake.

Here are some frequently asked questions about cancer-fighting foods.
What is the number one cancer-fighting food?
There is no single food that can fight cancer. However, consuming certain foods can provide the body with the nutrients it needs to help reduce the risk of cancer. These include apples, berries, cruciferous vegetables, carrots, fatty fish, and more.
How do you starve cancer cells naturally?
According to Cancer Research UK, some early studies, mostly in animals, have suggested that some cancer cells do not use ketones for energy. This would mean that consuming a diet that is low in carbohydrates and high in fat can help to starve cancer cells by lowering glucose levels.
However, more research into this is necessary. It is best to contact a doctor for advice before making any significant dietary changes.
What is the best mushroom to fight cancer?
In Japan and China, medicinal mushrooms have been approved for the treatment of cancer alongside standard therapies. There are
Research into preventing cancer through diet is still in the early stages and requires further testing.
However, it is important to remember that eating a balanced diet containing fresh fruits, vegetables, and good fats will benefit overall health.
People can speak with a healthcare professional if they are concerned about their cancer risk.
