1)Most of the food we eat can be influenced by whom?

2)Food choices come from what?

Answers

Answer:

1) Hunger, savor, appetite. Three main biological reasons why we eat. Also, the economic ability to pay for the food. And the fisical capability to go and buy food, to cook.

2) Our physiological needs are the main reason why we choose food. People need energy to survive.

Everyone would like to have the possibility to eat what he wants. But food choices depend on the financial situation, social class, and preferences.

That is why poor people or people who have less money to spend on food, often eat food that can feed more people but it doesn’t have nutritional values. When people have money, they immediately have a wider spectrum of groceries that can choose from.

Explanation:

Savour is equal to enjoying. When people are not hungry they are happier. We choose what to eat depending on the look, taste, smell, texture. As sweets smell good, people consider them the most attractive food. Food is not just the source of nutrition, it is also the source of satisfaction.
