Supermarket

I think what to eat is depend on what body needs. I think everything has its own benefit to our body in different way. Maybe there are something are called unhealthy food, but may be it can be cooked in different way to make it healthier. For example, rice can be unhealthy food, too, when ones can not absorb the sugar within it. As I went to the supermarket, I started to think more about the food economically and nutritionally.


Economically:
Is it good to use metal or plastic to make containers for soda?
What can some other materials are made for packing the foods?
Where are the foods from?
Will they be better (fresher) from local?
Which one cost more money, shipping or the food itself?
What makes the competitions of the food companies?
Are the foods in the supermarkets cleaner than the markets?


Nutritionally:
How to reduce the calorie in the food?
Is the lower calorie food, the better for us?
What other things can replace the nutrition of the fruits?
Will the people care about the food’s nutrition?
What makes people think about the nutrition?
