Excellent Nutrition Site I just discovered


This is a new site I found a few days ago and has some excellent info - it reinforces that which we already know: http://www.paleonu.com/

Here is his 12-step process for getting started with your Paleo diet:

PaNu - A modified paleolithic diet that can improve your health by duplicating the evolutionary metabolic milieu.

How do you do it?

Here is a 12- step list of what to do. Go as far down the list as you can in whatever time frame you can manage. The further along the list you stop, the healthier you will be. There is no counting, measuring, or weighing. You are not required to purchase anything specific from me or anyone else. There are no special supplements, drugs or testing required.*

1 Eliminate sugar (including fruit juices and sports drinks) and all flour

2 Start eating proper fats - Use healthy animal fats to substitute fat calories for carb calories. Drink whole cream or half and half instead of milk.

3 Eliminate grains

4 Eliminate grain and seed derived oils (cooking oils) Cook with butter, animal fats, or coconut oil.

5 Get daily midday sun or take 4-8000 iu vit D daily

6 Intermittent fasting and infrequent meals (2 meals a day is best)

7 Fruit is just a candy bar from a tree. Stick with berries and avoid watermelon which is pure fructose. Eat in moderation.

8 Eliminate legumes

9 Adjust your 6s and 3s. Pastured (grass fed) dairy and grass fed beef or bison avoids excess O-6 fatty acids and are better than supplementing with 0-3 supplements.

10 Proper exercise - emphasizing resistance and interval training over long aerobic sessions

11 Eliminate milk (if you are sensitive to it, move this up the list

12 Eliminate other dairy including cheese- (now you are "orthodox paleolithic")

If you can do step 1, that is about 50% of the benefit and alone a huge improvement on the standard American diet (SAD) By about step 6 you are at about 75% , by step 9 about 80% and at 10 you are at 99% for most people.

Here is the skeleton of the theory:

Insulin is a phylogenetically old hormone. It is a biological messenger that in excess, is metabolically saying the following to your tissue and organs: "Go ahead and store energy, and go ahead and mature, reproduce and die." Excess insulin in humans is linked to diabetes, alzheimer dementia, metabolic syndrome, obesity, coronary disease and cancer.

We did not evolve under conditions of insulin excess. Food was intermittently available and not superabundant like today. Scarcity and famine were frequent everywhere until recently in evolutionary time. Preferred foods were available year round and dense in calories and nutrients. Animal products, including organs and bone marrow of mammals, fish, and invertebrates (insects) were the preferred foods, supplemented by edible plants (not grains) until the dawn of agriculture. Fruit was seasonal and not yet bred for maximum sweetness. Food was eaten less frequently, had lower carbs than the typical American diet which is about 60%, and was supplemented by often involuntary periods of intermittent fasting and lower calories overall.

We are not adapted to chronic hyperinsulinemia.

We are also not adapted to eating grass seeds, to which we have been significantly exposed for only about 10,000 years. They contain molecules that are specifically designed to discourage consumption, as well as other problematic chemicals.

The diet is not about eating exactly what "cavemen" ate, or killing your own food. It is solely about duplicating what I believe are the key elements of the internal hormonal metabolic milieu that we evolved under from especially less than 1 million years ago to about 10,000 years ago. This is likely to be achieved not by eating specific things, but more by not eating specific things.

Calorie restriction is a severe, uncomfortable way to have low insulin levels and if calorie restricted (starving) your insulin levels can be reasonable even if your carb percentage is high. However, with calorie restriction you can get muscle wasting, fatigue and weakened immune function. In animal models, calorie restriction increases longevity substantially. Remember the metaphorical message of insulin? It says, "Mature, Reproduce and then Die". This message is attenuated by having low insulin levels.

Is there another way to live in a world of abundant food without being hungry all the time, yet avoiding the risk of immune dysfunction associated with eating grass seeds that cannot even be eaten without mechanical processing and cooking ?

Yes, you can work your way down this list.

Check the website occasionally for more details - I will elaborate as time allows - or you can post questions in the comment section of the blog.

* This is not medical advice. I am confident this is the healthiest way to eat based on currently available science. However, if you have any serious medical condition that requires treatment and in particular if you take medication for diabetes, thyroid disorders or autoimmune diseases, make dietary changes only in consultation with your physician. Your medications may need to be adjusted, as you may well need less of them!

Great article! Guess I need to do that fasting thing---uggg!

Jenn,

The key thing with fasting is EVERYTHING else has to be in order - sleep, stress, general nutrition...

If all of these are not in order, fasting can have a deleterious effect, rather than a beneficial one.

If you want, I can email you some articles on IF (intermittent fasting).

Jenn Kruse said...

Sure Don! I thoroughly checked out the PaNu blog last night...interesting....

Dave Taylor said...

Don this is some great info that give alot of background, but I really agree with you on the poin that fasting is only approprate when other items are in order. It makes it very hard to follow and needs to be attacked with care.

Oh yea got Good Cal Bad Cal and have made it about a 1/4 the way through and its pretty amazing how all the info was suppressed

Ya, Good Calorie, Bad Calorie is a good read!

centurion_crossfit forthood said...

Yeah, I have been readign a lot there the last few days as well. Pretty much the same info as Robb Wolf or Gray Taubes espouse.

Good Calorie, Bad Calorie is a must read book! Truly eye opening.
