Dr. Oz suggests raw food

The Dr. Oz website has a whole section on raw foods, called The Raw Food Challenge, designed to help you transition to a raw foods diet. I’m floored. After the last few years of listening to mainstream news talk about how crazy those raw foodists are (It’s all an eating disorder! Enzymes aren’t necessary!), here’s the Doc himself showing people how to switch to a raw food eating plan.

What do you guys think? Would you consider a raw foods diet if your doctor told you to think about it? Would you be more or less likely to consider eating raw if you had cancer?

Me, I think I’d love to go mostly raw someday, if it’s possible for me to get all my macronutrient requirements met with my finicky taste buds, but I can’t imagine being 100% raw. I really appreciate Carmella’s comment at the end of this post (filled with beautiful photographs!) about how she eats a little cooked food now and then, and doesn’t try to be so rigid with her eating. I love the idea of eating a nutrition-soaked diet, but I don’t like the idea of never being able to eat out with friends, or of forcing my dinner hosts to do anything more complicated than, “No meat please”.

Milk elevates insulin levels

According to Loren Cordain’s blog:

Milk elevates insulin as much as white bread. Constantly elevating plasma insulin levels may lead to insulin resistance, which is at the root of several metabolic diseases such as obesity, type 2 diabetes or hypertension.

Hmmmm. Does that seem odd to you? Being lactose intolerant myself and a vegan groupie, I don’t mean to root for dairy or anything, but this just seems off. Looking for the glycemic index of white bread and milk, I find this:

White Wheat Bread    75(GI)
Milk, full fat                  39(GI)
Milk, skim                     37(GI)

I posted a comment on Cordain’s blog asking how they arrived at their conclusion. It apparently needs to be approved before it shows up, but I’ll let you know what happens.

Canned food contributes to breast cancer?

This was a new one for me. According to this article in The Daily Green:

In addition to being found in many plastic bottles, Bisphenol A is also found in the epoxy resin liner of most canned fruits and vegetables. The BPA from this lining has been shown to leach into the vegetables in the can. Studies have shown that amount leached is enough to cause breast cancer cells to grow and proliferate in the lab.

I’ll look around and see if I can find more support for this, but for now let’s just take it as one more encouragement to eat whole foods, and to support our local agriculture, and while you’re at it, support the EARTH. That plastic you throw away might literally be going into someone else’s body.

Aussies come up with a great food show

In Australia there’s a new show called Food Investigators. The episodes are free to watch online for 30 days after they air. I’m currently watching episode 4, which you can find on this Episode Guide. It talks about “functional  foods”, or foods that are enriched with various things to make them more nutritionally sound, like plant sterols in margarine or omega 3s in eggs (and in Australia, they have Omega 3-enriched bread!). 

It’s a great show for nutrition buffs, and episode 4 is especially great if you like listening to Aussies pronounce “margarine”.

Are running shoes useless?

On a bbs I’m on, a link was posted in response to a friend asking about shoes for starting the Couch to 5k program.

The link went to an article titled, “The painful truth about trainers: are running shoes a waste of money?

What I like is that they come to the conclusion that we’re basically better off as barefoot as possible, which as a massage therapist and reflexologist and a many-years member of the Society for Barefoot Living, I completely agree with. Shoes are a freaking menace! That’s my humble opinion. Okay, sure, I like my Chacos in the summer, but I go barefoot as much as I can, and you really do feel the difference after awhile. Your feet and legs get stronger, and your proprioception gets a lot sharper.

Turns out it’s not just us wacko hippies, it’s also endurance athletes:

Then there’s the secretive Tarahumara tribe, the best long-distance runners in the world. These are a people who live in basic conditions in Mexico, often in caves without running water, and run with only strips of old tyre or leather thongs strapped to the bottom of their feet. They are virtually barefoot.

Come race day, the Tarahumara don’t train. They don’t stretch or warm up. They just stroll to the starting line, laughing and bantering, and then go for it, ultra-running for two full days, sometimes covering over 300 miles, non-stop. For the fun of it. One of them recently came first in a prestigious 100-mile race wearing nothing but a toga and sandals. He was 57 years old.

It also turns out that running shoes don’t prevent injury at all – in fact there is no evidence for that claim, and the shoe companies know it.

So, if running shoes don’t make you go faster and don’t stop you from getting hurt, then what, exactly, are you paying for? What are the benefits of all those microchips, thrust enhancers, air cushions, torsion devices and roll bars?

The answer is still a mystery. And for Bowerman’s old mentor, Arthur Lydiard, it all makes sense.

‘We used to run in canvas shoes,’ he said.

‘We didn’t get plantar fasciitis (pain under the heel); we didn’t pronate or supinate (land on the edge of the foot); we might have lost a bit of skin from the rough canvas when we were running marathons, but generally we didn’t have foot problems.

‘Paying several hundred dollars for the latest in hi-tech running shoes is no guarantee you’ll avoid any of these injuries and can even guarantee that you will suffer from them in one form or another. Shoes that let your foot function like you’re barefoot – they’re the shoes for me.’

Researchers began filming barefoot runners……

When he zoomed in, he was startled by what he found. Instead of each foot clomping down as it would in a shoe, it behaved like an animal with a mind of its own – stretching, grasping, seeking the ground with splayed toes, gliding in for a landing like a lake-bound swan.

‘It’s beautiful to watch,’ Pisciotta later told me. ‘That made us start thinking that when you put a shoe on, it starts to take over some of the control.’

Pisciotta immediately deployed his team to gather film of every existing barefoot culture they could find.

‘We found pockets of people all over the globe who are still running barefoot, and what you find is that, during propulsion and landing, they have far more range of motion in the foot and engage more of the toe. Their feet flex, spread, splay and grip the surface, meaning you have less pronation and more distribution of pressure.’

All this is making me want to go for a jog in my Vibram Five-Fingers, the weirdest looking shoes I’ve ever owned, but the neatest and most fun to wear. Definitey worth the money! If you’re looking to go barefoot without worrying about stepping in something scary, get a pair of Vibrams.
