Miscellaneous / Mark Sisson, Mat Lalonde, Robb Wolf talk
« on: August 09, 2011, 05:36:15 AM »
Mark Sisson: Primal;  Robb Wolf: Lean paleo, although more liberal on the sat. fat issue; Mat Lalonde: chemist who isn't really affiliated with any "brand" of paleo, but is focused on what's going on at a molecular level with ancestral diets and nutrition. 

A lot of it is these guys just chatting about various things in the paleo/primal/ancestral health "movement", which I found fascinating:


Research / Sodium intake as an indicator of metabolic syndrome
« on: June 22, 2011, 04:29:31 AM »
The full text isn't available yet on pubmed, but I'm posting this so I don't forget to check back in a couple weeks.

Abstract Aims. We investigated the association between daily sodium intake and each individual component of the metabolic syndrome (MS) as well as the metabolic cluster per se and clarified which of the combinations of MS features is particularly associated with sodium intake. Methods. A total of 716 subjects from our OPERA (Oulu Project Elucidating Risk of Atherosclerosis) cohort were selected to fill in a food follow-up diary for a 1-week period. The MS was determined using the International Diabetes Federation (IDF) criteria. Results. Subjects with the MS used more sodium (P < 0.001), less carbohydrate (P < 0.001), less fibre (P = 0.031), and more alcohol (P < 0.001) than those without the MS. High sodium intake was strongly related to elevated BMI (P = 0.003), waist (P < 0.001), and higher fasting blood glucose (P < 0.001). The subjects with the highest sodium intake suffered more often from type 2 diabetes (P = 0.007). Sodium intake was highest in the group where all the MS criteria were present (P < 0.001). High sodium intake was a statistically significant predictor of the MS in logistic regression analysis (P = 0.009). The highest sodium intake was observed in the IDF criteria combination waist + glucose + blood pressure. Conclusions. These findings suggest that a reduction in sodium intake may be especially beneficial in the treatment of individuals with the MS.

Mouse study, but interesting:

Krystal and his colleagues implanted various strains of mice with human tumor cells or with mouse tumor cells and assigned them to one of two diets. The first diet, a typical Western diet, contained about 55 percent carbohydrate, 23 percent protein and 22 percent fat. The second, which is somewhat like a South Beach diet but higher in protein, contained 15 percent carbohydrate, 58 percent protein and 26 percent fat. They found that the tumor cells grew consistently slower on the second diet.

Miscellaneous / Ash Wednesday
« on: March 09, 2011, 05:35:14 AM »
Today is Ash Wednesday.

While I haven't been a practicing Catholic since I was in high school, I've continued to observe Lent.  Something about the spiritual nature of it keeps me honest when it comes to giving up things.  Occasionally I'll do something for others instead, but this year I'm making it about me.  :P

So, this year, I'm giving up non-paleo foods, except for nightshades and a few of the "fairly safe" new world foods like avocados and squash - and non-paleo drinks except for herbal tea.

This means no coffee or cocoa (the hardest ones), and no social alcohol consumption (second hardest).  There are several other cheats that are less frequent, but that are weaknesses of mine when they're available.

Anybody else doing something similar?

Research / Diet soda may up stroke risk
« on: February 10, 2011, 05:18:46 AM »
It's just a preliminary study showing correlation, not necessarily causation, but if anyone needs further encouragement to drop the diet drinks:

A recent study suggests drinking diet soda may significantly increase the risk of having a stroke or other vascular system disorder.

Researchers at the University of Miamiís Miller School of Medicine said in a statement that people who drank diet soda every day have a 61 percent higher risk of having a vascular event, compared to people who donít drink any soda.

The researchers said their findings suggest switching from regular soda to diet soda is not an effective strategy in lowering the risk of heart disease and stroke.

The study included 2,564 participants who were asked about their soda consumption habits. During an average follow-up of 9.3 years, 559 vascular events occurred, including ischemic stroke, which is caused by the rupture of a weakened blood vessel.

The researchers said that the risk of this type of stroke remained high, even when accounting for other risk factors, including a patientís metabolic syndrome, peripheral vascular disease and heart disease history.

The study was presented at the American Stroke Associationís annual conference in Los Angeles, Calif.

Miscellaneous / It's 4 degrees F outside...
« on: December 14, 2010, 09:46:51 AM »
...and I was able to walk the dog without shivering.

That never would have happened before Paleo, no matter how many layers I wore.  I was musing how it's been so easy for me to get acclimated to the cold this year; I haven't had to resort to long underwear just to be comfortable in the apartment.  My husband pointed out that it's the first winter we've been eating this way.


Diet and nutrition / How to stay in ketosis
« on: November 18, 2010, 04:42:55 PM »
What's the maximum amount of carbs that can be consumed without getting out of ketosis?

Following a few particularly low carb days earlier in the week, I had killer headaches, but felt great today.  The ketostix are saying that I'm in ketosis, and I'd like to stay in for a little bit to let my body adjust and hopefully prevent the headaches in the future.

Research / Researchers dispute report on early butchers
« on: November 18, 2010, 03:58:36 PM »

Microscopic analysis of marks on bones that one study thought to be indications of stone tool butchering by A. afarensis shows that the marks are more likely to have been made by animals.

This moves the date of stone tool butchery from 3.4 million years ago, back up to 2.5 million years ago.

Recipes and meal photos / Slow Cooker Carnitas
« on: November 10, 2010, 06:05:19 AM »
I modified this slightly from the recipe here:

6 lb bone-in pork roast

3 tsp cumin
3 tsp garlic powder
1.5 tsp oregano
1.5 tsp ground coriander
1 tsp salt
1 tsp fresh ground black pepper
1/2 tsp cinnamon
2-3 bay leaves
3 cups chicken broth

Quarter the roast (optional), rub all sides with the spice mixture, then place the pork on top of the bay leaves in the slow cooker.  Slowly add the chicken stock.  Cook on low setting for 10 hours (or, if you are short on time like I was, high for 3 hours, then low for 2 hours).

Once meat is easily shredded with a fork, remove from slow cooker, pull the pork, and fry in tallow or lard until the meat is a little crispy. 

We topped it with homemade guacamole.  Next time I'm going to add cilantro - we didn't have any this time around.

Progress Reports & Photos / Health Screening/Blood Work Results
« on: October 21, 2010, 06:17:33 AM »
Just got back from a health screening.  My husband's work gives us financial incentives if you get screened and meet their (lenient) goals for various health markers.

27 y/o female with a family history of high LDL and low HDL:

Height: 5'6
BMI: 19.9
Total Cholesterol: 172
LDL: 70
HDL: 93
Fasting Blood Glucose: 87
Blood Pressure: 116/80

I'd had strong black coffee about 45 minutes before the test, which is why the BP is a touch high.  Usually it's low-normal.

The pharmacist said my HDL was the highest she'd ever seen.  ;D

Research / Caveman Parenting
« on: October 18, 2010, 04:13:53 AM »
A couple of my old professors are quoted in this.  Dr. McKenna does most of his work on mother-infant sleep patterns and SIDS prevention.

Edit: Unfortunately, the article painfully oversimplifies both people's research and makes it sound like it was pulled out of thin air.

Research / Paleo for women past childbearing age?
« on: October 17, 2010, 08:57:46 PM »
Does anyone know anything about paleo-type diets for women past child-bearing age?  My mother, who has a tendency towards high LDL cholesterol despite being a healthy weight,  thinks the paleo diet sounds interesting but is worried it would raise her levels.  She doesn't discount everyone's stories on here, but wants to see research or bloodwork from women her age.  I'd already passed on the high carb and heart disease article, but that doesn't really address high fat diets.

Her dad died at 32 of a heart attack, so she's understandably freaked about going against conventional recommendations.

Miscellaneous / "How not to fight colds"
« on: October 07, 2010, 02:33:57 PM »

Here was a new insight in cold science: the symptoms are caused not by the virus but by its host ó by the bodyís inflammatory response. Chemical agents manufactured by our immune system inflame our cells and tissues, causing our nose to run and our throat to swell. The enemy is us.

Thereís another intriguing paradox here. Studies suggest that about one in four people who get infected with a cold virus donít get sick. The virus gets into their bodies, and eventually they produce antibodies to it, but they donít experience symptoms. It may be that people like this are not making the normal amounts of inflammatory agents.

I wonder if this is part of why, on the paleo diet, people seem to have much weaker symptoms compared to the average sick dude?  My thought is that eating the SAD leads to excessive inflammatory responses, which leads to the body overreacting to the cold virus and producing tons of snot, sore throat, and fever.  Eating paleo reduces the inflammation so that our bodies work at resolving the illness without so much drama.

Miscellaneous / Chip in cast iron seasoning?
« on: September 17, 2010, 07:04:44 AM »
We have a cast iron pan that we inherited from my husband's grandmother.  Yesterday about a 1" chip came off the inside edge of it, down to the unseasoned metal.

Do I just re-season the whole pan, or is there something special I should do to prevent further chipping?


Diet and nutrition / How much should I feed this guy?
« on: September 13, 2010, 08:57:27 AM »
My awesome husband is joining me in eating Paleo, mostly out of moral support.  He's healthy and active already, unlike me, who gets sick if I stray from the straight and narrow. :)

He is having problems with fatigue and a little depression a few days in.  I'm cooking breakfast and dinner, and have been packing his lunches just to make sure he's getting enough food - if left to his own devices, he'll eat less than I do, and nowhere near enough protein and fat. 

Can someone give me an idea of how much and in what proportions a 27 y/o, 5'11, 160 lb guy should be eating?  From the body fat % example pictures in another thread, we're guessing he's around 16%. He plays ultimate frisbee for a few hours a week, and does strength training (nothing huge, can get details if needed) around 3x per week.  The whole "eat until you're satisfied" thing doesn't work with him right now.  The guy just doesn't seem to be able to tell when he's hungry.

Thank you!
