Recently, I've decided to eat better and was exposed to Forks Over Knives, which was the basis for the change. I have since figured out that eating is like smoking/drinking/drugs; it is just another way someone can die if abused. Since I tend to think we all pick the way we want to go (short of an accident), trying to convince most people (here in the US) that what they put in their body matters, is the same 'pick your poison' argument.
Like someone mentioned above, I figure I'm not too old to see if I can make MY quality of life better as I age (I"m nearing 60) and though I didn't have any health problems and ate more like the typical American, after viewing the video and doing some research, I decided to give it a try. Now, almost 3 years later, I can say I basically feel the same in that I have no loss of energy, same health level, but I DO notice now when I stray and have a meal made up of heavy dairy (still can't give up pizza, but I'm working on it) or heavy-fat foods, any kind of red meat, that my system definitely reacts negatively. I'm not a strict vegan but about 90% of the time, I try to eat whole foods. One important lab test in the vid shows the percentage of bad effects of eating animal protein went up sharply as intake reached over 5%. I now try to keep mine at that mark.
Again, everyone sees this differently but one stat that really made me think is that over 800,00 die from heart disease per year in the US. Made me think it was more of a problem then what I thought it was.
It's a hard habit to break, eating like we do (typical American cuisine, etc) and since there is no 100% surety that carnivores always die early and badly, I still believe NOT putting all the processing and 'unnatural' chemicals into my body has to help as I get older. The caveat I have here is that there ARE alternatives that are just as tasty. And truthfully, I'd never have switched if I hadn't found replacements that were just as good.
The usual YMMV is as true here as drinking and drugs, imo.
