'Research indicates that healthy eating can be beneficial for people living with cancer. Studies show that benefits may include reduction in symptoms and treatment side effects and improved quality of life. Healthy eating can also help prevent other conditions that cancer survivors may be prone to such as obesity, diabetes, heart disease and osteoporosis. Another important benefit is enhanced psychological and emotional wellbeing. This can be due to the person with cancer having an increased sense of control over the recovery process; this in turn leads to a reduction in stress.'
