I just made version #2, and it was delicious. My pan was slightly larger, but I kept the 30 minute cooking time. It came out more golden brown on the outside, but it was perfectly moist. This is SO much tastier than store loaves, and I love slicing it thick. I greased my pan with butter and coconut oil and lined it with wax paper on the bottom, and it slipped right out.
If you're interested in the paleo plan but don't think you want to be so strict, you don't have to be all-or-nothing with your approach. Consider adopting some eating patterns from paleo and skipping the ones that don't work for you. For example, try just eating more fruits and vegetables and cutting down on added sugars. If you feel unsure about grains or dairy, talk to your doctor or a registered dietitian to determine what's best for your body.
Baking with almond flour can sometimes be tricky and not all brands give you the same results. Actually, the one you cited is my least favorite and usually makes baked goods sink in the middle, get very dense and also crumbly. I highly suggest you use one of the brands of blanched almond flour I recommend. My favorites are by Honeyville, Welbee’s and Nuts(.com). Here’s Welbee’s on Amazon for $23 for 2 LB http://amzn.to/1M5cDzG
The NY Times had a blog article on Good News on Saturated Fat which is reporting on Gary Taubes's interpretation of the new report in The New England Journal of Medicine on a two-year diet experiment in Israel. A followup is the post The Fat Fight Goes On where Gary rebuts the arguments against the study. And here's a good interview with Taubes (and includes a good summary): Gary Taubes on Cold Fusion, Good Nutrition and What Makes Bad (and Good) Science.
I made this yesterday. I made 1.5 times the recipe for a larger loaf pan and used apple butter (no sugar, just reduced apple) instead of yogurt or coconut butter. I had the same issue with the center being uncooked. Lesson learned that it needs to stay in longer but the pieces we cut off from around the center were very good. I was very impressed with this recipe. Thank you!
Oils are trickier. Loren Cordain, Ph.D., founder of The Paleo Diet Movement, breaks down which oils are healthy on the paleo diet: olive, walnut, flaxseed, macadamia, avocado and coconut oils are all allowed because they were gathered directly from the plant. While our hunter-gatherer ancestors probably did not consume flaxseed oil, it is allowed because of its content of high alpha-linolenic acid (ALA), a type of heart-healthy, anti-inflammatory omega-3 fatty acid.
The digestive abilities of anatomically modern humans, however, are different from those of Paleolithic humans, which undermines the diet's core premise. During the 2.6-million-year-long Paleolithic era, the highly variable climate and worldwide spread of human populations meant that humans were, by necessity, nutritionally adaptable. Supporters of the diet mistakenly presuppose that human digestion has remained essentially unchanged over time. https://www.youtube.com/watch?v=zhL5DCizj5c
