EAT-FIBRE STUDY
Are you an identical twin aged 18 or over living in the UK?
Researchers at TwinsUK, King's College London's world-leading twin research programme, are investigating whether diet can help protect against early-onset bowel cancer.
Cases of bowel cancer in people under 50 are rising, and we don't yet know why. As a twin, you have a unique role to play in helping find answers.

Getting started
Clinic visit 1: We'll take body measurements, health checks, and samples (blood, urine, stool, saliva, and cheek swab), and ask you to fill in health and lifestyle questionnaires.
Diet allocation: You'll be randomly assigned to either the EatWell Guide diet or a modified version — both are designed to be healthier than the average UK diet.
Ongoing support: A dietitian will be in touch via up to 4 video or phone calls to guide and support you throughout. Food will be delivered to you via supermarket delivery.
Throughout the study
During the 12 weeks: You'll be asked to complete a short weekly questionnaire (around 3 minutes) on your digestive health, plus up to 5 food diaries. At the midpoint, you'll collect a small sample set at home and post it back in prepaid packaging.
Clinic visit 2 (week 12): We'll repeat the first visit measurements and samples.
12 months: You'll be asked to complete a final set of questionnaires and a home sample collection.
