Analysis was used in the study in order to investigate if the price elasticity evaluations mentioned in the literature are numerically relatively equal and if not, to describe the deviation in the elasticities so that one may be able to make some conclusions. Considering the fact that the aim of the study was a correlative reassessment of previous researched regarding the subject of the paper : 160 studies were collected where the price elasticity for food products were evaluated.
The variables assessed were food product, data characteristics , estimates of price for all foods and estimates of cross-price elasticity for main substitutes and complementary foods. The major estimate in this research was how the change in price for soft drinks can alter their consumption.
Different analytic approaches to modelling food demand were compared. During the analysis , 16 food and beverage categories were used, including ( cereal , beef , dairy products , eggs , food from outside , fruit , juice , soft drinks , sweets and vegetables.
The descriptive statistical analysis of 16 food and beverages groups showed that results are reliable with customary characterizations of the demand response to food prices as inelastic. All mean price elasticity estimates were below 1.0 and vary from 0.27 to 0.81. The relatively less inelastic products were soft drinks ( 0.79) and meats (0.75). Food outside the home was most responsive to price changes ( 0.81).
This data help link the public health and economics communities. Another benefit is that such data will lead to beginning of establishing a vision of where the change in price might have a supreme impact on customer food choices and physical condition. However despite having enough published articles there are still gaps in research base. These gaps must be filled , in order to achieve a complete understanding of political influence on a public health . According to the study there is evidence which propose that low-income populations are more sensitive to price changes than the largely population.
The main factors affecting individual dietary choices are taste , cost and nutritional value of products. The problem of obesity is connected to extreme consumption of added sugar and fat. Because of the low cost those products are more popular. Therefore the price of food and marketing practices are an important component of the eating environment. The strategies of price reduction encourage the alternative of targeted foods by declining their price relative to alternative foodstuff choices.
