See if they will switch to light olive oil for cooking. Not ideal but short of coconut oil or butter it is a better choice than vegetable oils. Also let tem know you want to start cooking dinner. To get the hang of it. :-)

Tell her vegetable oils will make her skin wrinkled.

Processed vegetable oils (like canola and corn) are rancid by the time they hit the bottle. Rancid, in this case, just means that the oil has started to oxidize. Oxidized means the oil if full of free radicals, which have been linked to aging (including causing your skin to wrinkle prematurely).

Anti-oxidants counter free radicals cased by oxidized food. The benefits of anti-oxidants to prevent wrinkles is touted far and wide by beauty companies. So, it shouldn't be too hard to explain to your mom that vegetable oil contains the bad oxidants the anti-oxidants fight.

BTW, there is a "how it's made" episode on canola oil. I believe it is on youtube. It shows the entire process, including the chemical extraction, heavy heating, bleaching, and deodorizing. After watching that, it shouldn't be too hard to explain to her why the oil is rancid before it is bottled.

There is some good info here:

I had my husband watch the movie Fat Head and that was fairly convincing for him. He still eats non-paleo at meals I don't prepare but he's much more on board with coconut oil and butter now. So happy he doesn't fear the fat now.

Ultimately you won't have to eat what they eat for too much longer. And in the mean time you can still add IN healthy fats at dinner. Bring on the butter or coconut oil, even if you are the only one that eats it. Vegetable oil isn't going to kill you, not optimal, but issues around food can be really stressful. As you get healthier though, you may notice that you CAN'T eat soy oil, give me an awful tummy ache, maybe that would make them change?

I think you can look at it this way. You're 19, and ready to start making your own decisions. Now is the point in your life where your lifestyle becomes your own, not simply the product of your parents. I'm pretty sure there are good resources on paleo blogs, for example:

http://www.robbwolf.com/faq/

From there you can find some articles on good fats.

My point though, too, is to let your parents see you reading these things. Actions will speak louder than words, and if you suggest they read it too, they will see your interest in things paleo. Maybe they won't change mcuh, but they'll hopefully be open to the changes you're making

I like the idea of you doing your own cooking. My 17-yr-old grandson does all of his. Most times it's paleo but, if not, I honor his preferences. In his case, his meals are my healthy food and he gets his neolithic fix with rice cereal and moderate soda. If your parents agree, on the nights you cook substitute healthier ingredients and when they cook try to add healthy choices and eat sparingly from the bad stuff.

When you know you're eating veg oil, you might try to compensate by eating a can of sardines for O-3 balance. Just a thought.

Food for more thought: What if they were the ones who'd made a radical diet change and you were being forced to change just because you live with them? I like your goal to be healthy, but for now just try to get along and compromise where you can. All too soon you'll HAVE to buy and prepare all your food. It's better to laugh and tease about your different goals than allowing it to become a source of friction.

Special note on the pizza: Since I have to be no-wheat for health reasons, when the grand-kid wants pizza I grab toppings off a piece or two and flesh out my meal with salad or vegetables out of the fridge. If your parents are receptive to having produce around you could do the same and that would be a powerful gesture to show you're serious about this. Also, nearly everyone accepts that produce is healthy.

http://vanessaruns.com/2011/02/08/gmos-and-why-you-should-never-use-canola-oil/ There's a nice one (ha! nice!?) on how Canola oil causes nerve damage.

Don't bother; if they question you, you let them know you've been doing your research on primal and paleo diet and desire to eat more biologically healthy -- not according to gov't funded health studies done during WWII. I'm 21. I tried to explain but it always results in arguing. Let bygones be bygones and eventually maybe after a couple years they may begin to grow more curious. I have found that trying to explain paleo to my folks is like trying to explain concepts like evolution by natural selection or that the Bible was a man-made story. (btw: I do not think evolution is required to back/support paleo.. that's just making it too complicated for the layman).

But the egg thing is absurd that you're eating too many. I myself, eat 2-3 eggs a day; it's absolutely fine. I recommend high Omega-3 flax-seed fed and veg.-fed hens or better. It's more expensive but it's your health you're paying for.

btw: Focus your energies on making $$ and get out of folk's place. Their lectures on your health will get on your nerves I guarantee!

Have them read a book called DEEP NUTRITION, particularly the chapter on Vegetable Oils and Sugar. But the whole book is EXCELLENT...
