An in-depth look at Non-Celiac Wheat Sensitivity at Hunter-Gatherer including the envy-inducing standard of care IBS sufferers received in Italy and the quality of controls.

Among those who were wheat sensitive, a high number of them tested positive on the cytomteric basophil activation test, and many also tested positive for serum IgG and IgA AGA tests. Many of these patients suffered from anemia and weight-loss. Biopsies showed eosinophil infiltration of the duodenal and colon mucosa.
, despite not having the type of villous atrophy damage associated with celiac.

There seemed to be two groups of IBS wheat-sensitive patients- those with wheat sensitivity alone and those with wheat sensitivity AND multiple other sensitivities to cow’s milk and other foods. The later group was also more likely to also have other types of allergies (non-food allergies, skin allergies, etc.) and a family history of allergies.

Acetylcholine is responsible for ahem, moving things along, so it might explain why wheat causes diarrhea in some people.

Also, it is notable that this study used wheat rather than gluten, so it might be other components of wheat like fructans that are responsible for the symptoms.

Dr Davis (of Wheat Belly) dismisses the benefit of sprouting grains.

It is folly to believe that such a process as simply allowing the seed to germinate somehow disables all the bad potential of modern wheat. It still contains the gliadin protein that clouds your thinking and stimulates appetite. It still contains glutens that disrupt intestinal health. It still contains amylopectin A that sends your blood sugar through the roof. It still contains lectins that disable the normal intestinal barriers to foreign substances. It still contains apha amylase, peroxidases, lipid-transfer proteins, and thioredoxins responsible for a variety of allergic phenomena.

Proof that the plank is better than crunches.

There are two disadvantages to old-fashioned sit-ups and crunches. In the long term they are likely to lead to back problems because of the pressure they create on the discs between the vertebrae, and, more to the point, they are not very effective. The muscles in your midsection area are not so much meant for moving your torso, but above all to keep your torso stable when your spine is subject to tension.

News around the web

Have you registered for the Paleo Summit – its being advertised as a virtual Paleo conference. I’ve signed up, it will be interesting to see how it turns out.

A look at breaking the exercise to eat cycle. Eating and Exercise are not morally loaded actions but so many treat them that way.

Realize that you do not need permission to eat. You don’t have to earn your calories. You’re a beautiful person worthy of eating just by virtue of existing. Even if you do nothing but sit on your butt, you have earned the right to eat and to eat food that is enjoyable.

Exercise is not punishment. You should find a way to move your body that you enjoy. While no exercise is 100% fun 100% of the time, I’m convinced everyone can find a way to be active that is challenging, fulfilling and mostly fun. If you hate running, please don’t run! (And to my readers who love running – you keep on running, I don’t mean you!) Dance, hike, bike or join a synchronized swim team (and then tell me how they get all that makeup to stay on in the pool!) but find something you love.

 

An interview with  female powerlifter, Jean Fry :

Of course! My most recent meet was about 6 weeks ago (at the Powerstation Pro-Am), marking my 4-yr anniversary at Westside. I squatted 415lbs and deadlifted 375lbs at a body-weight of 123lbs; I also scraped out a pro total with 1025lbs (despite having a terrible bench day). My best benches to date are 250lbs at a body-weight of 123lbs and 230lbs at a body-weight of 114lbs.

 

Mark Sisson looks at the need to eat brightly coloured vegetables and sulfur rich vegetables. While  artificial antioxidant supplementation continues to be shown as useless.

Stumptuous looks at the need to eat meat. Over at Hunt, Gather, Love – a review of Why Women Need Fat. Gnolls.org examines why humans became smarter rather than just more numerous.

More evidence that exercise doesn’t have to be time consuming, just hard – yes its interval training!

Not Just a Man looks at a couple of studies:

Activity levels affect bone density in women.

As expected, bone density by the BUA measurement increases noticeably with the increase in activity levels.  While VOS also increases, it doesn’t seem to be a significant movement so perhaps activity levels only really impact the structure of the bone rather than its elasticity and exact mineral content?

Strength training and adiposity in Women:

Moving over to the training group there is a much bigger reduction in body fat percentage with almost double the lean mass gains seen by the control group and a statistically significant reduction in fat mass when compared to the control group.  Despite the adherence drop-off in training during year two that was so evident in the strength measurements, the lean mass mostly remained with the trainees, although body fat started to return in year two.  Despite this, the body fat did return at a slower rate than the control group were putting it on, perhaps thanks to the additional muscle the trainees were carrying in year two.

Strength training has also been linked to better cancer survival rates. Exercise also seems to trigger stem cell growth in muscles, as well as just making you feel damn good

A look at the continually changing role of marriage in human society.

A study looks at the role of compression pants in recovery. They found a statistically significant advantage but at this point can only hypothesise as why.

Rob Wolff looks at how to carb-load.

Skeptic North calls for an end to funding of CAM* in education (*psuedoscience and superstition masquerading as health care).

Loren Cordain – Origins and Evolution of the Western Diet: Health Implications for the 21st Century

I stumbled across a fascinating lecture by Dr Loren Cordain looking at human evolution and their diet, and how that affects our modern health.

Another reason to exercise – it helps your body get rid of damaged or degraded cells.  And while exercise preserves muscle – it only preserves the muscle you use so don’t stop the full body routines… and sorry to disappoint – stretching doesn’t stop the doms.

How to ensure good gut health.

A new study suggests the marathon won’t kill you (if you’ve trained for it). Mark Sisson gives some advice on combining weight training with running, and here are some more tips to run faster.

A study postulating that most of humanity evolved with carbohydrate scarcity causing a greater insulin resistance to be selected for which is now what presupposes many ethnic groups for type2 diabetes.

Looking into the wider animal kingdom – researchers have discovered predators will hunt to ensure a nutritionally balanced diet.

Morning People – that’s as good as you’re going to be. Me, my brain’s just warming up!

Conditioning Research takes a look at the importance of sleep and its effect on obesity.

Evolvify takes a look at the (lack of) evidence behind the women like alpha males theory in pickup culture.

Despite being the ready energy source of many – another study suggests avoiding carbohydrates will help you stay awake.

Lifehacker looks at the science behind a bad mood.

From Not Just a Man’s World – a look at a study on the effects of resistance training on flexibility for young women.

Loren Cordain answers a few questions on the paleo diet – its going to take me a while to get through his paper on Cereal Grains.

A good reminder of the power of the placebo.

So, grains are essential, huh?

Dr Cordain – Knowledge of our Ancestral Diet

Dr Cordain has responded to the inevitable but grains must be important claim based on lack of pre-history knowledge…
