What is the dollar amount spent on food world wide?

Answer 1

I don't have teh answer to your question, but would note that it would be significantly less than the value of all food produced or consumed. This is because a very large proportion of people around the world are subsistence farmers, who grow all of their own food and so don't spend money on it directly (although they spend time producing it and may need to buy spades and other tools).

Also, it is difficult to get a meaningful figure since a banana is just a banana no matter what country you buy it in, but varies in value from a cent or so in some poor countries up to $2 in parts of Australia at the moment. This means that any attempt to try and value food spending across countries and currencies will be very difficult to construct on a comparable basis so that you can meaningfully sum them. Therefore, I don't like your chances of getting an answer to this question, but I will cross my fingers for you.
