What is the connection between nutrition and cancer?
The foods we eat can affect our risk of developing certain types of cancer. High-energy and high-fat diets can lead to obesity and are generally thought to increase the risk of some cancers. Enjoying a wide variety of nutritious foods as described in the Australian Dietary Guidelines may help to prevent cancer.
How does nutrition cause cancer?
Being overweight can increase cancer risk in many ways. One of the main ways is that excess weight causes the body to make and circulate more estrogen and insulin, hormones that can stimulate cancer growth.
What foods do cancer cells feed on?
All cells, including cancer cells, use glucose as their primary fuel. Glucose comes from any food that contains carbohydrates including healthful foods like vegetables, fruits, whole grains and dairy.
What role does nutrition play in boosting the immune system?
 These nutrients help the immune system in several ways: working as an antioxidant to protect healthy cells, supporting growth and activity of immune cells, and producing antibodies. Epidemiological studies find that those who are poorly nourished are at greater risk of bacterial, viral, and other infections.
What increases risk of cancer?
The most common risk factors for cancer include aging, tobacco, sun exposure, radiation exposure, chemicals, and other substances, some viruses and bacteria, certain hormones, family history of cancer, alcohol, poor diet, lack of physical activity, or being overweight.
