Fats -- coconut oil and butter are very healthy. Coconut oil, especially, is good for frying because it is very stable even at high temperatures.

And though these are a healthy part of any diet, generous amounts of them aren't suitable for all. I got an order of krill oil in America from Mercola.com and was also sent a copy of his new book, "Take Control of Your Health," which includes a chapter about nutritional typing. I am a protein type and I match his list of criteria for that type exactly. Then there are carb types -- a smaller proportion of the population, but people who actually do well on the more mainstream recommended diet of low fat, low protein, and grains (veg and whole grains are still best). There are also mixed types. Apparently one clue to which type you are is whether you like white or dark meat from chicken or turkey. Protein types like the dark meat and carb types like the light meat. Mercola says that some of the sickest people that have come to his clinic have been protein types following a vegetarian diet. You can read more about nutritional typing on his site here. You don't have to pay for the official test, just look around his site and read the articles.

I do wish coconut oil were cheaper. It's wonderful stuff. I'd use it all the time if I could.
