How many days has Brian figured he has been stranded?

Explanation:

The most obvious reason would be to keep us alive. Every living thing needs to take in nutrients and calories for growth and repair and to keep metabolic processes functioning. However, I’m guessing you are looking for a more creative response than that.

Food is important because it literally makes up every part of us. We are made of what we eat. The quality of our structure, down to the cellular level depends on the quality of the food we take in on a daily basis. It constantly astonishes me that food is so important to our very existence and people give little to no thought about it. I mean, would you rather be built out of McDonald’s or vegetables grown in your own garden?

Third, food is important because it is the cornerstone of culture. Every country, every region, around the world has its own food. People have adapted to their surroundings, depending on what is most available, and these food traditions are passed down from one generation to the next. Traditional foods tend to be healthful as well, because processed food is a relatively new advent. Think of a culture and what comes to mind first? I’m guessing their traditional food is probably at least in the top 5.

In case my first and second reasons are a little too similar, here is a bonus reason. Food is important because real, whole food contains nutrients in their natural form and their intended ratios. No vitamin can replicate the exact formulation that nature has provided in the fresh foods we eat. I used to think it was possible to survive on vitamins and minerals alone. I mean, why else do we need food except for the raw materials that it provides? I never actually did this experiment, but now I understand that nature has plenty of secrets up her sleeve and I could never formulate a vitamin regimen that could come close to what she has already done for us.
