Because there is an increased chance of food bourne pathogens in our food supply, I think of it as equal to a good old fashioned game of Russian Roulette (which is much more exciting than vomitting
!). That said, yes I do feel that adding raw foods to the diet can be of help. There are enzymes that are important to get in raw veggies. I like to grow my own (without using animal crap in the soil, where ecoli can get into them). Juicing is one good way.
I also have 3
Aero Gardens to grow some indoors with hydrophonics and no soil. It's supper clean, and being home grown there is very little chance of the type of contamination that food processors could easily add. Though, don't expect to save any money, as it is very pricey per pound even after the machine is paid for. The taste and convienance is worth it for me. I love having home grown tomatos and Basil in the dead of winter!
Another thing to think about are the benifits of adding things like EVOO cold to maintain the benifits omega fatty acids, and adding fresh herbs at the end of a cooked dish to keep the vitamins and minerals of them intact (although they are only a small portion of the diet-every little bit helps).
As with any diet, moderation is key. If a person would cut the fried food they eat in half, and sub it with raw food, the impact would be quite synergistic! So sub out those fries for a salad, and you could be well on your way to being much healthier!
