Are Low-Carb Diets Safe and Effective for Children?

DietDoctor Andreas Eenfeldt has located three studies that answer in the affirmative. Click through to his blog for details.

Should You Try Intermittent Fasting?

Dietitian Brenna has some definite thoughts on it after her recent experiment.

I”ve done a couple 24-hour fasts in the last year (notes here and here).

Dietriffic’s Melanie Thomassian has a thoughtful post on fasting, too.

R.I.P.: A Horse Named Steve; and a Neurosurgeon Confronts His Own Death

The New York Times online has the story:

As soon as the CT scan was done, I began reviewing the images. The diagnosis was immediate: Masses matting the lungs and deforming the spine. Cancer. In my neurosurgical training, I had reviewed hundreds of scans for fellow doctors to see if surgery offered any hope. I’d scribble in the chart “Widely metastatic disease — no role for surgery,” and move on. But this scan was different: It was my own.

Well worth your time to read unless you’re in denial of death.

A pall hangs over the Parker Compound since one of our horses died of colic yesterday. Certainly not the same as a human death, but still….  

My wife and daughter rescued Steve from appalling conditions  eight or nine years ago when he was about seven years old. They named him after me for some reason—his original name was Wyatt. Sunny paid $200 (USD) for Steve, which is one cheap horse. Many horses are like boats and airplanes in that they may not cost all the much initially—it’s the maintenance and repairs that get you.

The seller in Apache Junction, Arizona, had him in a large pen with 20 or 30 other horses. At feeding time, the owner threw a few flakes of hay into the pen and then it was “survival of the fittest” time. Horses are not by nature sharing creatures. Steve was not high up on the pecking order. If she hadn’t bought him, he may well have ended up in a meat market.

Steve was originally my daughter’s first horse, not mine. For reasons forgotten, we got her another horse, Buckwheat. Steve was to be my wife’s horse then. Soon enough Sunny broke her leg and was out of commission for months. Horses, like people, need exercise. The most fun way to exercise them is to ride them. That’s when I first started riding Steve, to give him exercise. My daughter and a cowgirl named Angel Antan were my instructors.

I had an odd experience with him one time when my daughter and I were on a trail ride to the Verde River from our home in Rio Verde. If you don’t know how to ride, note that a horse isn’t supposed to move or stop unless the rider gives the signal. You can’t let the horse be in charge. We were in a dry wash when Steve suddenly stopped and started sniffing the ground. I had no idea what was up and thought I’d just sit there waiting to see what would happen. Soon and without warning, Steve knelt down on his front legs, then his back ones, and was on his belly, starting to roll over! I jumped off and pulled him up by the reins before he did the deed. You do NOT want a horse rolling over on you, or your saddle for that matter. He never did that again, nor have I heard of that happening to others.

One of the cool things about our trail rides is that you can get close to coyotes. When you’re on horseback, the coyotes don’t perceive you as much of a threat.

Steve always liked men more than women. It was only in the last few months that my wife and he became quite fond of each other.

My wife gave him a great home. He was a good horse who taught me how to ride. I always felt safe when I was around him and on him, regardless of the near roll-over.

He “colicked” every year for the last five years. I’d like to think that Steve’s in horse heaven with his buddy Buckwheat, running over grassy  hills and wading through clear streams. RIP, Steve. No more pain, ever.

Easily Make Your Own Vinaigrettes and You Won’t Have to Wonder What’s In Them

Our new cruet

Our new $8 cruet

If you’re trying to lose weight or keep from getting fat, salads are helpful. I recommend them in my Advanced Mediterranean Diet, Low-Carb Mediterranean Diet, Paleobetic Diet, and Ketogenic Mediterranean Diet.

My favorite salad dressings are vinaigrettes. They can be as simple as olive oil, vinegar, salt and pepper. The problem with most commercial vinaigrettes is the label says “_____ Vinaigrette with olive oil,”but the first listed ingredient is soybean oil (or some other industrial seed oil) and olive oil is somewhere down the line.

Get around that by making your own. Here’s a recipe and a salad to try it on. Also, if you’re watching your carb consumption, the commercial dressings  may sneak in more than you want. Again, avoid that by making your own.

You can make a vinaigrette in a jar with a lid. Add the ingredients then shake to create an emulsion. Or do it in a bowl with a whisk. My wife found us a cruet at the supermarket that I’m hoping will allow mixing, storing, and pouring all from the same attractive container. I’ll let you know if it doesn’t work out; I’m afraid it will leak when I shake it.

Steve Parker, M.D.

Update January 28: As feared, it leaks when you shake liquid contents. Anyway, it makes an attractive container for olive oil, especially if you buy it by the gallon.

Got Abdominal Obesity? Improve Your Health With Mediterranean Diet and High-Intensity Interval Training

…according to the Heart and Stroke Foundation. Some quotes:

The study found an average reduction in waist circumference of eight centimeters [3 inches], a reduction in systolic blood pressure of 6 mm Hg and an aerobic fitness improvement of 15 per cent over the first nine months of the study.

Improvements in waist circumference, blood pressure and fitness can lead to numerous other health benefits including a reduced risk of developing high blood pressure, as well as improving osteoarthritis symptoms, quality of life, physical functioning, and cognition.

The high-intensity interval training was done two or three times a week over 20-30 minutes each session. Click for an example of HIIT on a stationary bike. More basic info on HIIT.

The classic Mediterranean diet has too many carbohydrates for many diabetics, although it’s better for them than the Standard American Diet. That’s why I devised the Low-Carb Mediterranean Diet.

QOTD: Mark Steyn on Judges

In my cultural tradition, a judge is just a bloke in a wig. He may be a smart bloke in a wig, or he may be an idiot in a wig. But the wig itself is not dispositive. As the English barrister F E Smith is said to have responded when a judge asked if he was trying to show contempt for this court, “No, my Lord. I am attempting to conceal it.”

Has Eating-Out Contributed to Overweight and Obesity?

So easy to over-eat!

So easy to over-eat!

The U.S. trend of increasing overweight and obesity started about 1970. I wonder if eating away from home is related to the trend. I found a USDA report with pertinent data from 1977 to 1995. It also has interesting info on snacking and total calories consumed. Some quotes:

“We define home and away-from-home foods based on where the foods are obtained, not where they are eaten. Food at home consists of foods purchased at a retail store, such as a grocery store, a convenience store, or a supermarket. Food away from home consists of foods obtained at various places other than retail stores (mainly food-service establishments).”

***

“Over the past two decades, the number of meals consumed has remained fairly stable at 2.6 to 2.7 per day. However, snacking has increased, from less than once a day in 1987-88 to 1.6 times per day in 1995. The increased popularity in dining out is evident as the proportion of meals away from home increased from 16 percent in 1977-78 to 29 percent in 1995, and the proportion of snacks away from home rose from 17 percent in 1977-78 to 22 percent in 1995. Overall, eating occasions (meals and snacks) away from home increased by more than two-thirds over the past two decades, from 16 percent of all eating occasions in 1977-78 to 27 percent in 1995.”

***

“Average caloric intake declined from 1,876 calories per person per day in 1977-78 to 1,807 calories per person per day in 1987-88, then rose steadily to 2,043 calories per person per day in 1995.”

***

“These numbers suggest that, when eating out, people either eat more or eat higher-calorie foods or both.”

Parker here. I’m well aware that these data points don’t prove that increased eating-out, increased snacking,  and increased total calorie consumption have caused our overweight and obesity problem. But they sure make you wonder, don’t they? None of these factors was on a recent list of potential causes of obesity.

If accurate, the increased calories alone could be the cause. Fast-food and other restaurants do all they possibly can to satisfy your cravings and earn your repeat business.

If you struggle with overweight, why not cut down on snacking and eating meals away from home?

Low-Carb Diets Poised for Resurgence?

I’ve been predicting major renewed interest in l0w-carb weight loss diets for the  last three or four years. Perhaps it’s starting. Evidence? Two recent online articles noting increased sales at Atkins Nutritionals. Here’s one at NPR and one at TakePart. The search terms “low-carb diet” didn’t reveal any blip at Google Trends, however.

My Advanced Mediterranean Diet (2nd edition) offers a low-carb option that’s worked well for many, along with a traditional portion-control program.

Book Review: Zest for Life – The Mediterranean Anti-Cancer Diet

51VBKOWQ3dL._SX258_PJlook-inside-v2,TopRight,1,0_SH20_BO1,204,203,200_.jpg

A couple years ago I read and reviewed Zest For Life: The Mediterranean Anti-Cancer Diet, by Conner Middelmann-Whitney, published in 2011. I guess I forget to pull and re-post my review off my old Advanced Mediterranean Diet blog. Per Amazon.com’s rating system, I give it five stars (I love it). Here it is.

 ♦   ♦   ♦

The lifetime risk of developing invasive cancer in the U.S. is four in ten: a little higher for men, a little lower for women.  Those are scary odds.  Cancer is second only to heart disease as a cause of death in western societies.  The Mediterranean diet has a well established track record of protecting against cancers of the prostate, colon/rectum, uterus, and breast.  Preliminary data suggest protection against melanoma and stomach cancer, too.  I’m not aware of any other way of eating that can make similar claims.

So it makes great sense to spread the word on how to eat Mediterranean-style, to lower your risk of developing cancer.  Such is the goal of Zest For Life’s author.  The Mediterranean diet is mostly, although by no means exclusively, plant-based.  It encourages consumption of natural, minimally processed, locally grown foods.  Generally, it’s rich in vegetables, fruits, legumes, olive oil, whole grains, red wine, and nuts. It’s low to moderate in meat, chicken, fish, eggs, and dairy products (mostly cheese and yogurt).

Note that one of the four longevity hot spots featured in Dan Buettner’s Blue Zones was Mediterranean: Sardinia.  All four Blue Zones were characterized by plant-based diets of minimally processed, locally grown foods. (I argue that Okinawa and the Nicoya Peninsula dwellers ate little meat simply due to economic factors.)

Proper diet won’t prevent all cancer, but perhaps 10-20% of common cancer cases, such as prostate, breast, colorectal, and uterine cancer.  A natural, nutrient-rich, mostly plant-based diet seems to bolster our defenses against cancer.

Ms. Middelmann-Whitney is no wacko claiming you can cure your cancer with the right diet modifications.  She writes, “…I do not advocate food as a cancer treatment once the disease has declared itself….”

She never brings it up herself, but I detect a streak of paleo diet advocacy in her.  Several of her references are from Loren Cordain, one of the gurus of the modern paleo diet movement.

She also mentions the ideas of Michael Pollan very favorably.

She’s not as high on whole grains as most of the other current nutrition writers.  She points out that, calorie for calorie, whole grains are not as nutrient-rich as vegetables and fruits.  Speaking of which, she notes that veggies generally have more nutrients than fruits. Furthermore, she says, grain-based flours probably contribute to overweight and obesity. She suggests that many people eat too many grains and would benefit by substituting more nutrient-rich foods, such as veggies and fruits.

Some interesting things I learned were 1) the 10 most dangerous foods to eat while driving, 2) the significance of organized religion in limiting meat consumption in some Mediterranean regions, 3) we probably eat too many omega-6 fatty acids, moving the omega-6/omega-3 ratio away from the ideal of 2:1 or 3:1 (another paleo diet principle), 4) one reason nitrites are added to processed meats is to create a pleasing red color (they impair bacterial growth, too), 5) fresh herbs are better added towards the end of cooking, whereas dried herbs can be added earlier, 6) 57% of calories in western societies are largely “empty calories:” refined sugar, flour, and industrially processed vegetable oils, and 7) refined sugar consumption in the U.S. was 11 lb (5 kg) in the 1830s, rising to 155 lb (70 kg) by 2000.

Any problems with the book? Only relatively minor ones. The font size is a bit small for me; if that worries you, get the Kindle edition and choose your size.  She mentions that omega-6 and omega-3 fatty acids are “essential” fats. I bet she meant to say specifically that linolenic and linoleic fatty acids are essential (our bodies can’t make them); linolenic happens to be an omega-3, linoleic is an omega-6.  Reference #8 in chapter three is missing.  She states that red and processed meats cause cancer (the studies are inconclusive).  I’m not sure that cooking in or with polyunsaturated plant oils causes formation of free radicals that we need to worry about.

As would be expected, the author and I don’t see eye to eye on everything.  For example, she worries about bisphenol-A, pesticide residue, saturated fat, excessive red meat consumption, and strongly prefers pastured beef and free-range chickens and eggs.  I don’t worry much.  She also subscribes to the “precautionary principle.”

The author shares over 150 recipes to get you started on your road to cancer prevention.  I easily found 15 I want to try.  She covers all the bases on shopping for food, cooking, outfitting a basic kitchen, dining out, shopping on a strict budget, etc.  Highly practical for beginning cooks.  Numerous scientific references are listed for you skeptics.

I recommend this book to all adults, particularly for those with a strong family history of cancer.  But following the author’s recommendations would do more than lower your risk of cancer.  You’d likely have a longer lifespan, lose some excess fat weight,  and lower your risk of type 2 diabetes, dementia, heart disease, stroke, and vision loss from macular degeneration.  Particularly compared to the standard American diet.

Disclosure: The author arranged a free copy of the book for me, otherwise I recieved nothing of value for writing this review.

Did You Waste Money on Sensa?

The U.S. Federal Trade Commission has taken action action. Janet Helm has the details. For example:

The makers of  Sensa will need to pay $26.5 million to consumers to settle federal charges that the company used deceptive weight-loss claims and misleading endorsements to sell these sprinkles.

The FTC charged that California-based Sensa Products, LLC, its parent, and Sensa creator Dr. Alan Hirsch and CEO Adam Goldenberg, deceptively advertised that Sensa enhances food’s smell and taste, making users feel full faster, so they eat less and lose weight, without dieting or exercising.
