Here in Los Angeles, "raw food" has become a big trend. Several raw food restaurants have opened up in recent years, where nothing you eat is cooked. It can be ground up, sliced, diced, and put in a blender, but never cooked.
Even the soups are cold. (I'll never forget my friend ordering a soup at a local raw food restaurant, only to realize that it - duh! - wasn't hot!)
I enjoy eating raw food, but I find myself only being able to stomach so much of it at a time. I suppose some raw food purists will accuse me of being too tainted by my Western diet...but personally, I need more carbs to survive.
So I like raw food as an addition to my regular diet, but not a lifestyle. I think it's always a good idea to add more raw fruits and veggies to a diet. I'd actually love to take a class in raw food "cooking" (an oxymoron!). But doing it 100% isn't my thing.
