So, glad this board update is over with because I've come across some much info over the weekend I want to post.
Here are some little details that are usually left out in diet/health advice:
About plant based Omega 3 sources and our ability to convert them, or supposed lack of ability:
(This one is for you, pokemonster)

Plant based omega-3 sources like flax,hemp and chia seeds are high in ALA, but low in EPA and DHA. Although ALA is an essential nutrient, it is important to remember that the conversion of ALA to the far more essential EPA and DHA is typically quite inhibited by impaired delta 6 desaturase, an enzyme necessary for you to convert the ALA into the longer chain EPA and DHA.
Elevated insulin levels impair this enzyme and more than 80 percent of the U.S. population has elevated insulin levels. Because of this it is important to include animal based sources of omega-3 fats in your diet.
Found in this blog post about how krill oil is the best source of omega 3s.

So apparently elevated insulin levels, as is typical in the Western diet habits, impairs ability to convert ALA from plants to the EPA and DHA. So, if we ate how we were meant to, without all the sugar, refined carbs, high glycemic juices and overeating, we might just be able to get our omega 3s from plants the way all the other animals do. Animals that rarely spike their insulin levels. Makes sense to me and something to look into for those that don't want to consume animal sources.

Coconut Oil, ketones, thyroid and fuel for the brain (preventing Alzheimer's/dementia)
So, I've only previously seen a lot of vague stuff about coconut oil being good for the metabolism and the thyroid, but no real explanations. Chukylard recently brought up that coconut oil stimulates ketones, (without having to do the extreme low carb thing, woo hoo.) In this recent Mercola article listing his '10 best foods' to keep you healthy, despite being a brief few paragraphs, includes some real, relevant details. Like an article should.

1) Your body sends medium-chain fatty acids directly to your liver to use as energy. This makes coconut oil a powerful source of instant energy to your body, a function usually served in the diet by simple carbohydrates.
2) apparently it is this instant energy affect on your metabolism that increases the activity of your thyroid. Yeah, yeah, more info is needed there.
And 3) ketone bodies may provide alternative fuel for the brain which has it's own insulin/glucose metabolism system going on and can become insulin resistant. See
research by Dr. Mary Newport,
Also, your body converts lauric acid into monolaurin, which has anti-viral, anti-bacterial and anti-protozoa properties. And, of course, it's about the best oil for cooking because, among other things, it is stable with a high smoking point.
(Note that butter from grass fed cows is another source of medium chain saturated fatty acids.)
