The structure of fats and fatty acid consumption in elderly people with cardiovascular system diseases

Abstract

Background: Patients with cardiovascular system diseases having their origin in arteriosclerosis require special dietetic treatment. Among many nutritional components, fats in the diet (both their quantity and quality) play a very important role in primary and secondary prevention of these diseases. Objectives: The aim of the study was the estimation of total fats participation (saturated fatty acids, mono-and polyunsaturated fatty acids and cholesterol) in the Daily Nutritional Ration (DNR) of elderly people with cardiovascular system diseases. Material and Methods: The study included 128 persons (66 women and 62 men, mean age 73.2 ± 6.9) hospitalized in the 1st Clinic of Cardiology and Hypertension, UJCM in Kraków. Daily intakes of energy were estimated using the 24-h nutritional recall and Food Frequency Questionnaire. Results: A higher consumption of fats and fatty acids was observed in men's diet than in women's diet. The percentage of energy from saturated fatty acids (10.6% M and W) was higher than dietary recommendations. The consumption of monounsaturated fatty acids was in accordance with nutritional recommendations. The participation in the diet of polyunsaturated fatty acids was insufficient versus the newest nutritional recommendations and was determined as 4.6% of energy in DNR in men and 4.1% of energy of DNR in women. Conclusions: The excessive amount of saturated fatty acids together with the insufficient amount of polyunsaturated fatty acids in the diet are the result of the excessive consumption of products which are a source of animal fat and insufficient consumption of plant fat, fish and seafood.
