Cardiovascular disease (CVD) is one of the most deadly diseases globally. In recent years, the incidence rate and the fatality rate of CAD has ranked first in China. CAD not only seriously damage public’s health but also cause property losses to patients’ family and the society. Therefore, the factors that affect the incidence of CAD are considered. Based on a research, that different eating habits and the body mass index among different regions are closely related to its incidence is proposed. The knowledge of linear algebra is then used to establish three models to get a healthy diet which helps to prevent CVD. In the first nutrient model, the purpose is to solve for a combination of food that can meet the nutrition requirement. In the second replacement model, some replacement tricks are used not only to deal with no or negative solutions problems but also to replace food which is beneficial to prevent CVD. Finally, the last energy model is used to check if the recipe satisfies the daily energy intake requirement. Eventually, a recipe which is flexible and contains various types of food is put forward. It ensures that people not only take in all kinds of nutrients and required energy daily but also prevent CVD. |
