More knowledge on the nutritional consequences of such advice is needed. This study aimed to explore how advice on modified fibre and lactose intakes during pelvic radiotherapy was associated with nutrient intakes amongst patients with prostate cancer.<h4>Methods</h4>A total of 77 Swedish men who underwent radiotherapy (50/2 Gy + boost 20-30 Gy) in 2009-2014 due to prostate cancer were given dietary advice at radiotherapy onset (baseline) and at 4 and 8 weeks after radiotherapy onset, to modify their fibre and lactose intakes. At baseline, the participants completed a food frequency quUpsala journal of medical scienceshttps://www.ebi.ac.uk/biostudies/studies/S-EPMC9199583biostudies-literatureAssociations between dietary advice on modified fibre and lactose intakes and nutrient intakes in men with prostate cancer undergoing radiotherapy.PMC9199583Forslund MSoderstrom LJohansson BRosenblad AOttenblad AfalseAssociations between dietary advice on modified fibre and lactose intakes and nutrient intakes in men with prostate cancer undergoing radiotherapy.<h4>Objectives</h4>A variety of non-evidence-based dietary advice on modified fibre and lactose intakes are provided to patients undergoing pelvic radiotherapy to counteract treatment-related bowel symptoms.
