Healthy lifestyle is in demand all over the world

Healthy lifestyle is in demand all over the world: the amount of people who care for their own body rapidly increase. Healthy products are more expensive than conventional packaged one , because of increased demand and more complex technological process of production are, but this doesn’t stand on the way of their sales. In 2017, sales reached an impressive $ 749 billion, representing 34% of the total sales of packaged food products around the world.
Economic problems , such as diminishing of income or dramatic increases in food prices might lead to changes in consumer behaviour. It is significant to understand such effect of economic conditions on diet quality , especially in low-income groups. The main dilemma is that the factors like increasing food prices and reduction in income create pressure to consume the foods lowest in cost , which is also lowest in quality, therefore lowest price makes calorie-dense foods more attractive.
It is important to mention that future research in this field should focus on predicting the impact of specific public health policies aimed at improving diets and reducing the burden of chronic disease.
The results obtained in this study can also be useful for specialists studying issues related to trade (import), customs, health, subsidies and social security issues. However, in this article, it seemed impossible to consider income elasticity and demand elasticity based on cross prices, which is also crucial for any analysis of food consumption, and therefore further research in this way can provide useful and important information.
