Research / Okinawan diet data
« on: January 19, 2014, 02:09:13 PM »
Vegetarians love to claim that the Okinawa diet proves the healthiness of a plant based diet.  Turns out, back when Okinawans were more healthy than other Japanese, they also ate 20% more meat:

They also ate more greens.  Granted they also ate more tofu, so it's not an example of a paleo diet, but it's certainly not an example of meat being bad for you either.

In my opinion the reasons Okinawans used to be long lived was because they simply ate less food, essentially being calorically restricted, but that argument is too subtle to open with against rabid vegetarians.

Diet and nutrition / Argh GMO strawberries
« on: January 07, 2014, 11:25:13 AM »
I've been eating a couple pounds of strawberries each week - they don't have a lot of sugar, and they're one of the few fruit that has vitamin C levels comparable to wild fruit.  I generally get organic strawberries, because they're so delicious.

When organic strawberries aren't available, I get regular strawberries.  I've been noticing over the last year or so that when I eat a lot of regular strawberries, I tend to get sniffles and feel like I'm coming down with something. I just chalked it up to the sugar, thinking that maybe the 20g of sugar in a pound of strawberries was enough to mess up my immune system a bit.

However, apples and pears don't have the same effect.  So what's going on?  Well, a few days ago after a I had these problems I finally checked into the possibility that the strawberries were genetically modified.

Turns out they are!  A lot of stawberries now are genetically modified with a gene that improves their cold resistance.  The source of the gene?  Peanut.  Seems likely that the peanut gene produces something that I'm mildly allergic to.

Ah well, looks like I'm going to have to start limiting myself to organic strawberries, which aren't allowed to be GMO.

Research / GERD, SIBO, and carbs
« on: December 02, 2013, 08:38:07 PM »
Just wanted to post a link to a good article by Dr. Eades on GERD - gastroesophogeal reflux disease, also known as acid reflux or heartburn.  Apparently excessive bacteria in the small intestine - small intestine bacterial overgrowth, or SIBO - produce gases while fermenting carbohydrates that push stomach acid back up into the esophagus, causing the problem.  Complex carbohydrate is worse than sugar in this respect, because it digests more slowly and is thus more likely to reach the lower small intestine where there are more bacteria.

Parenting / Is breast milk a ketogenic diet?
« on: November 14, 2013, 08:54:02 PM »
I've been noticing recently that (warning:  TMI) my poop has been kind of sweet smelling, which I think is attributable to being in ketosis just as sweet smelling breath is.  Then I got to thinking that breast fed babies have kind of sweet smelling poop as well.  So I googled "baby sweet breath" and got millions of hits.  The babies in question were breast fed when it was mentioned.  Usually there was lots of advice to take the baby to the doctor right away to check for type 1 diabetes, but the babies ended up being pronounced healthy.

So, sweet smelling breath and poop?  Does this mean that most or all breast fed babies are in ketosis?  That would be interesting.  And does that answer the question of why acetone, which isn't a sugar, smells sweet to us?  I'm thinking there could be an evolutionary advantage to babies' smelling sweet to their parents.

If we ever have another baby, I'm going to use some ketostix to find out whether this is the case.

Miscellaneous / Diabetes: Asia's "silent killer"
« on: November 14, 2013, 10:49:49 AM »
The number of people with diabetes in China and India are each several times the number in the U.S.  It looks to me like this is roughly proportional to population.  Looks like Asian diets with "healthy carbs" aren't so healthy after all.

Miscellaneous / Where are you on the Global BMI scale?

Just for fun (since we know BMI doesn't mean that much):

Research / Carb cravings and intestinal flora
« on: September 19, 2013, 08:02:59 AM »
Interesting column from hyperlipid about how intestinal flora interact with diet to help maintain carb cravings.  As usual, hyperlipid goes beyond the known to the realm of speculation, but there are links to two studies showing that in mice, at least, removal of intestinal flora results in loss of excess fat.

Miscellaneous / Diet advice you've refrained from giving
« on: September 14, 2013, 10:35:26 PM »
So on another forum, someone was posting about how they hadn't managed to make any progress in the first 7 weeks of their 12 week program towards their goal of losing 5 kg.  I was so tempted to post this:

Most people can lose 5 kg of water weight in the first week of a ketogenic low carb diet, so you have 4 weeks to go before you really have to do anything!

However, I knew it wouldn't be appreciated - it's a diet "support" thread, not a diet advice thread - so I held the impulse until I could come here to vent it instead.

Anyone else holding back the urge to post diet advice on nonpaleo forums?

Miscellaneous / Princess Kate and low carb
« on: July 25, 2013, 04:43:01 PM »
Princess Catherine of Cambridge always looks amazing in all her recent pictures - better than movie stars, whose entire job is to look good.  Granted Kate's excellent taste in clothing helps, but apparently part of it is that she follows a low carb diet:

Perhaps, like her mother Carole who kicked off a Dukan diet craze after her elegant appearance in a Catherine Walker outfit at the wedding Kate laid off the carbs to prepare for her first big royal tour.

Miscellaneous / Cheese can be dangerous to your health
« on: July 05, 2013, 03:16:54 PM »
Whole Foods cheese recall:

http://www.usatoday.com/story/news/nation/2013/07/05/whole-foods-cheese-recall/2493423/

I'm kind of hoping this will mean the fruit section will be free of stinky cheeses for a few weeks.

Miscellaneous / Straining fat
« on: June 09, 2013, 01:11:37 PM »
I store my animal fat - mostly from uncured bacon and from roasts - for future use.  Supposedly it's best to strain the fat through a double layer of cheesecloth before storage, but I'm too lazy to do that.

I recently found that a tea strainer seems to work well for bacon grease, and reasonably well for roast drippings.

Do you store animal fat for later use, and do you strain it first?

Miscellaneous / No endometriosis
« on: May 25, 2013, 06:40:20 PM »
My wife just said to me, "I guess you noticed the blood stain on the sheet.  I'm still getting used to this 'no endometriosis' thing".  No warning is still better than a week of painful cramps each month, though!

John Hawks discusses a site of hunting remains from 2 million years go:

"This is John Speth's scenario for fat acquisition from lean animals. The brain is the last part of the body to become fat-depleted during times of stress. If hunters are energy-limited, further lean meat is not going to be valuable to them because protein takes energy to digest. What they need most is fat, and the most ready source of fat is the brain. Accumulation of head elements, whether from hunted or scavenged sources, is an effective behavioral strategy in those circumstances."

Research / Honey contains antibiotic component
« on: May 06, 2013, 04:57:30 PM »
"The study, authored by Canadian researchers at the University of Ottawa, found that in eleven isolates of three separate biofilms (Pseudomonas aeruginosa, and methicicillin-resistant and -suseptible Staphylococcus aureus), honey was significantly more effective in killing both planktonic and biofilm-grown forms of the bacteria, compared with the rate of bactericide by antibiotics commonly used against the bacteria."

Also,

So it's not basically the same thing as corn syrup, after all.  Perhaps the antibiotic effects help make up for the negative effects on the immune system from the sugar.
