I'm not sure what I think about the Paleo diet. It does make a certain amount of sense, but the emphasis on fat and protein is a little much for me. And maybe it's just that it's getting kind of tiring reading about yet another set of "what you should eat, what you must not eat" rules, another diet where you have to go to extremes to find your food. (Which is not an exclusive feature of paleo, by any means).
As I understand it, you're supposed to eat a lot of unsaturated fat, animal proteins, and fresh or raw veggies. Butter and oils of olive, coconut, avocado, and macademia nuts are okay. You can eat a little bit of fruit and nuts, but you're supposed to stick to low-sugar fruits. You're not supposed to eat dairy (at least not much), legumes, grains, cereals, veggie oils, or sugar. These are basics; if you're interested in finding out more, here's a link to a good site.
What I do like about Paleo is the de-emphasis on carbs. We eat way too many of them. And here is an excellent article, written by a Paleo enthusiast, which explains thoroughly and simply why they are so bad for you. I also like what he has to say about the evils of Big Agra --- they don't care about your health. Not news, not news at all, but it needs to be said over and over because there is so much advertising, so many temptations, so much misinformation thrown in our faces day after day. Meanwhile, agro behemoth Monsanto continues to contaminate organic fields with pesticides, create Frankenseeds (genetically modified organisms), and gain ground in world food domination. It's impossible to avoid them --- they have their fingers in every pie. Even my beloved Whole Foods is involved, forcing me to rethink my grocery shopping practices. I guess it really is best to buy local, from farmer's markets, or a CSA, whenever possible.
Speaking of people (corporations are people, don't you know) who don't care about your health, recently Gwen Olsen, a former pharmaceutical company representative, published a tell-all book about the industry and their appalling practices. Food Renegade has a great writeup on it that everyone should read. Confessions of an RX Drug Pusher is Olsen's account of her fifteen years as pharmaceutical rep, her own struggles with mental health issues, and the suicide by burning of her niece, Megan, who was attempting to withdraw from a cocktail of prescription psychiatric drugs.
We can't afford to be complacent about our health on any front. We have to educate ourselves and take charge. Don't get your information from the people who are trying to sell you something! That's difficult, because in a sense, everyone is trying to sell something --- but some have a lot more to gain in others.
As for Paleo ... well, let's just say I'm intrigued, and I'm going to do some more reading. I don't see myself adopting the strict diet, but the no carbs thing ... that is sounding right.
