Proper nutrition, combined with adequate physical activity, plays an important role in the prevention and treatment of various chronic diseases, such as osteoporosis and diabetes. The aims of this research refer to women who are involved in the project "Exercise and proper nutrition against osteoporosis and diabetes". The aim is to collect data on the daily intake of three basic nutritional components in the diet, which include proteins, carbohydrates and fats. Other aims were related to examining the frequency of bad eating habits, which include too little or too much intake of certain nutritional ingredients in the diet, in certain groups. The aims are to examine the frequency of bad eating habits with regard to chronic diseases, with regard to smoking status, and with regard to the completed level of education. The research was conducted in the form of a paper-and-pencil questionnaire, and the sample of respondents included 23 middle-aged and elderly women (over 50). The results of the research show that respondents daily consume a larger amount of protein and fat, and a smaller amount of carbohydrates than the reference values. It was also shown that respondents who suffer from chronic diseases consume more protein, carbohydrates and fat per day than respondents who do not suffer from the same conditions, but the differences did not prove to be statistically significant. Furthermore, female smokers had a higher daily intake of protein and fat, and a lower intake of carbohydrates compared to female who did not smoke. The mentioned difference in diet is also not statistically significant. The last result indicates a higher intake of protein and a lower intake of carbohydrates and fats in the diet of respondents with a lower level of education, compared to respondents with a higher level of education.
