Parkinson's disease (PD) is associated with nutrition related problems which affect the quality of life. The goal of our research was to evaluate the impact of nutritional assessment on the quality of life of patients with PD. An Android application, developed by »Jožef Stefan« institute within PD_manager project enables patients to create food dairy by taking photos of their meals. Six patients with idiopathic Parkinson’s disease were included, most of whom encountered overweight and constipation problems. All participants had insufficient daily dietary intake of calcium, vitamin E and polyunsaturated fatty acids, most of them also did not reach reference values for magnesium, vitamin C and folate. According to results of one week food dairy, blood examination report and dietary habit questionnaire, personalized dietary recommendations were prepared. Before nutritional intervention, and six months after giving dietary recommendations, body composition was measured using bioimpedance analysis device, patients were screened for malnutrition and their quality of life was rated using Unified Parkinson’s disease rating scale. The quality of life improved in 33,3 % of participants.
