TWIN sisters from Daventry will appear on a Channel 4 health show on Tuesday.
Kristin and Maren Hallenga, aged 25, will appear on The Food Hospital on Channel 4 starting at 8pm.
The series is looking at how food can be used to combat illness and the science behind using food in medicine.
Kristin was diagnosed with breast cancer at the age of 23, but by the time doctors realised what was wrong the cancer was deemed incurable, but she has been fighting to overcome it.
Kristin and her twin sister Maren went on to found CoppaFeel to promote awareness of breast cancer.
Kristin said: “The reason we got involved in the show is because we’re twins. It’s always interesting, from a medical point of view, when one from a pair of identical twins gets an illness because it allows you to test them. This series looks at whether what you put in your body affects the way it behaves.
“There is a proven link between certain illnesses, like skin conditions, and the type of things you eat. We’re on it because I’ve changed the way I eat to help fight the cancer.
“I don’t eat any meat or dairy, I try to get as much antioxidants and good greens as possible.
“It’s about eating in a way that makes your body strong, so it can resist the cancer as much as possible, and help it stand up to the treatments you have.”
The CoppaFeel campaign saw Kristin win a Pride of Britain Award in 2009.
Her campaign has also brought her into contact with David Cameron, and a host of celebrities, including Dermot O’Leary and Fearne Cotton to help spread the message.
