Paleo author reviews anti-paleo book

Paleo author reviews anti-paleo book:

The new book, Paleofantasy: What Evolution Really Tells Us about Sex, Diet, and How We Live, is billed as an “exposé of pseudoscientific myths about our evolutionary past and how we should live today.” It was written by Marlene Zuk, a professor of ecology, evolution, and behavior at the University of Minnesota.

Many people who follow the paleo regimen have reviewed the book on their blogs, but my favorite review so far is by Mark Sisson, author of The Primal Blueprint (my favorite paleo book). He says the problem with the book is that no one who follows paleo believes any of the straw man premises she sets up. In other words, Zuk’s idea of Paleo is the real paleofantasy and her arguments against her own straw man version of paleo were explored and accepted years ago by the Paleo community.

After reading the book, John Durant tweeted “Paleofantasy shouldn’t have been a book in 2013, it should have been a blog post in 2010,” and that’s as good a description as I can think of.

It’s all very uncontroversial:

There is no one paleo diet.

Who’s saying that? Humans have spanned the globe for millennia, surviving and even thriving in environments ranging from tropical to temperate, from arctic to near-aquatic, all the while subsisting on the wild foods available to those regions. Same basic diet of animals and plants, different configurations.

Evolution doesn’t just stop and humans didn’t just reach a state of perfect adaptation back before agriculture from which we’ve never progressed.

Sure. I talked about how we’re still “evolving” last year, even mentioning Zuk’s favorite topics – lactase persistence (35% worldwide, which is far from 100%) and amylase production. She discusses a few more recent changes, like malaria resistance, adaptation to high altitude, and earwax differentiation, but that’s it. If she wanted to, I’m sure she “could keep adding to the list” and mount an overwhelming case for widespread genetic adaptations to grain consumption, chronic stress tolerance, and sedentary living, but she’s saving up material for the next book. Or something. Either way, I’m not very convinced by her “list” of rapid evolutionary changes, especially considering most of them have little to do with the mismatches we discuss in this community and none of them are even present in a majority of humans.

Zuk is also quick to misrepresent “our” arguments so she can swoop in and take the sensible position – positions the ancestral health community has long occupied!

Is It All Just a “Paleofantasy”

Scheerer's phenomenon

Wow! This is so cool…from Wikipedia:

Blue field entoptic phenomenon

The blue field entoptic phenomenon or Scheerer’s phenomenon is the appearance of tiny bright dots moving quickly along squiggly lines in the visual field, especially when looking into blue light (such as the sky). This is a normal effect that can be perceived by almost everybody. The dots are due to the white blood cells that move in the capillaries in front of the retina of the eye, near the macula.

Blue light (optimal wavelength: 430 nm) is well absorbed by the red blood cells that fill the capillaries. The brain “edits out” the dark lines that would result from this absorption. The white blood cells, which are much rarer than the red ones and do not absorb the blue light well, create gaps in the blood column, and these gaps appear as bright dots.

In a technique known as blue field entoptoscopy, the effect is used to measure the blood flow in the retinal capillaries. The patient is alternatingly shown blue light and a computer generated picture of moving dots; by adjusting the speed and density of these dots, the patient tries to match the computer generated picture as best as possible to the perceived entoptic dots. This then allows calculation of the blood flow in the capillaries. This test is important in diseases such as diabetes which can cause retinopathy.

Scheerer’s phenomenon should not be confused with “floaters” or muscae volitantes. Scheerer’s phenomenon is distinguished by the appearance of multiple, identical-looking bright dots that follow each other rapidly along the same path. Floaters are variable in appearance; although they sometimes are dots, they often have the appearance of threads or shreds of crumpled cellophane. Floaters remain almost stationary or drift slowly and do not follow well-defined paths. They are due to debris floating in the vitreous humor of the eye.

Kid Foods Breed Fat, Picky Children

Good article on not giving in to picky eaters. Great quote:

I say that parents that lack the ability to convince a kid to voluntarily eat a plate of green beans aren’t cut out for parenthood. If you can’t outsmart a 3 year old, then what the fuck are you doing raising one?

Cheap, safe drug kills most cancers

From New Scientist:

It sounds almost too good to be true: a cheap and simple drug that kills almost all cancers by switching off their “immortality”. The drug, dichloroacetate (DCA), has already been used for years to treat rare metabolic disorders and so is known to be relatively safe.

It also has no patent, meaning it could be manufactured for a fraction of the cost of newly developed drugs.

Evangelos Michelakis of the University of Alberta in Edmonton, Canada, and his colleagues tested DCA on human cells cultured outside the body and found that it killed lung, breast and brain cancer cells, but not healthy cells. Tumours in rats deliberately infected with human cancer also shrank drastically when they were fed DCA-laced water for several weeks.

How to cure your asthma or hayfever using hookworm – a practical guide

Who knows – this may just work.  From kuro5hin:

This is my personal account of curing my asthma and hayfever by deliberately infesting myself with the intestinal parasite hookworm.

It isn’t for the faint hearted and for some should not be read while eating.

It involves a great deal of research, a trip to Cameroon and a lot of barefoot walking in open air latrines in west Africa.

If you have asthma, or know someone who has asthma (or for that matter Crohn’s disease, IBD or colitis) and are suffering badly you owe it to yourself to consider this approach. Because although it sounds strange and is repellant it is founded on sound science and it has one other virtue.

It worked.

11 Tips To Boost Your Metabolism

Found on ArticlesBase – original article by Andrew Bicknell (via Digg):

Boosting ones metabolism is something many people try to achieve everyday. Having a high metabolic rate increases the amount of calories, or energy, the body burns on a daily basis. Without optimal metabolism the body will store excess calories as fat for future use. The problem for many people is they don’t ever use these excess calories and as a result struggle with weight issues.

There are many factors that affect a person’s metabolism including age, weight, hormonal changes, lean muscle mass, diet, genetics, stress and the amount of physical activity undertaken on a daily basis. As you can see boosting your metabolism involves many factors, but the fact of the matter is that it is relatively easy to boost your metabolism if you are committed to doing so.

Here are 11 tips to help you boost your metabolism:

  1. Build lean body mass. As we age our bodies metabolism or ability to burn calories decreases. One way to offset this problem is by exercising. Lean muscle burns calories and the more you have the more calories you burn, even while resting. You can build muscle through resistance or weight training at least twice a week. You can also boost your metabolism by doing cardio exercises. You can choose to do this between or in conjunction with weight training. Simply going for a walk or using the stairs instead of the elevator are good ways to get in an aerobic workout.
  2. Eat Breakfast. Many people ignore eating breakfast. What they don’t realize is that it’s the most important meal of the day. Breakfast gives your metabolism a boost and provides a consistent energy supply throughout the day. The majority of people who eat a healthy breakfast have fewer weight and health issues than those who don’t.
  3. Sugar is bad. Processed and refined sugar such as found in sweets and soft drinks overload the body with sugar causing many serious health issues including obesity and diabetes. Complex carbohydrates are a better energy source because they supply an even level of blood sugar. The human body just isn’t built to deal with the large amounts of refined sugar most people include in their diet.
  4. Spicy foods that make you sweat can help boost your metabolism.
  5. Get a good night’s sleep. There is research that shows that people who do not get sufficient sleep tend to gain weight. This may be because the body uses sleep to heal and regenerate itself, including its muscular system.
  6. Drink more water. Water is the lubricant of the body. It also flushes toxins out of the body and keeps the kidneys operating at maximum efficiency. This allows the liver more time to do what it does best, metabolize fat stores.
  7. Eat small meals. Eat 5 to 6 small meals per day spaced 2 to 3 hours apart. This gives the body a steady supply of energy and prevents binge eating.
  8. Don’t miss meals. Skipping meals in order to loose weight is counter productive because it actually slow metabolism and can lead to over eating.
  9. Plan your meals. If you have a daily or weekly menu you are much more likely to stick to your plan.
  10. Drink green tea. Green tea has been shown to boost metabolism and unlike coffee does not stress the body with caffeine.
  11. Include more high energy foods in your diet including fruits, vegetables and whole grains. These provide a more balanced energy source and will not cause blood sugar spikes.

Boosting your metabolism can be done if you are dedicated to doing it. This does not mean you need to stress over each little thing but if you eat right and exercise you should see a decrease in body fat and a much more energetic and happy you.

'Superfoods' Everyone Needs

Interesting article on WebMD:

“Whether you’re trying to prevent cataracts, macular degeneration, cancer, or cardiovascular disease, the same type of preventive dietary measures apply,” he says. “The whole body is connected: a healthy heart equals a healthy eye and healthy skin. You’ll hear about all these special diets for special health needs, but really, the same diet and the same lifestyle choices prevent the same diseases. With rare exceptions, you don’t need 20 different preventive modalities — just one really good diet.”

And that “one really good diet,” Pratt says, should be founded on these “superfoods”:

  • Beans
  • Blueberries
  • Broccoli
  • Oats
  • Oranges
  • Pumpkin
  • Salmon
  • Soy
  • Spinach
  • Tea (green or black)
  • Tomatoes
  • Turkey
  • Walnuts
  • Yogurt

When incorporated into your regular daily diet, these foods, says Pratt, can stop some of the changes that lead to diseases such as diabetes, hypertension, Alzheimer’s, and some cancers. “I picked them out after researching all of the world’s healthiest diets: for example, Japanese diets, Mediterranean diets, and even some of the healthier dietary patterns in the United States,” he says. “I noticed that it’s the same food groups wherever you live.”
