The aim of the study was the analysis of the blood biochemical indices values depending on the nutrition model. The research was carried out in 1999 year among at random chosen 188 people 75-80 years old residing the neighbourhood of Olsztyn. The nutrients intake was assessed by means of the 24-hour recall method and, after having included loses, was compared with the recommended intake on the safe level. The blood biochemical indices were defined in the Central Analytical Laboratory of the City Hospital in Olsztyn according to the standard procedure. The analysis was assessed by Statistica v.6.0 program with the application of the factor and cluster analysis. Three nutrition models were separated: "low nutritive", "dairy" and "meat-vegetable-fruit". The comparison and distribution of the mean blood biochemical value was carried out using the variance analysis and the chi 2 test at p < or = 0.05. No differentiation in the levels of most blood biochemical indices depended on women and men nutrition model has been confirmed. Among 1-16% of women and 12-28% of men too low haematocrit and haemoglobin values were stated, among 34% of women and 23% of men--too low albumin values, and among 24% of women and 11% of men too high glucose values in the blood were found. About 32% of women and 35% of men showed too low HDL cholesterol ratio to total cholesterol content. Too low value of the vitamin B12 in the blood was revealed for 6% of women and 5% of men, and folic acid among 26% and 37%, for women and men, respectively. Regardless of realized nutrition model the significant percentage of elderly people has been characterized with the increased risk of cardiovascular diseases, diabetes or anaemia.
