Why I Eat ‘Mostly’ Plants?

Sunday, September 26th, 2010 by Karena
The health benefits and disease prevention of plants is what convinced me I had to change my habits

The 2nd most prevalent question I get about my new diet is “Why?”

Why would anyone eat only, okay ‘mostly’ plants?  For me, the two primary catalysts are my friend Cathy and the author of The Perfect 10 Diet.

Cathy died almost a year ago: breast cancer. While she was living, I pretty much ignored looking at possible causes, but she didn’t.  She had books stacked up next to her bed that only got higher as she got sicker. Each book purported to know the cause and the cure for her disease.  I hated all those books. Looking directly at the reality of her disease was, well… I just wasn’t up for it.

Secondly, I had Dr. Aziz on my radio show.   About halfway through the interview Dr. Aziz recommended that we, as Americans, eat a diet that is 40% fat.  Yep, 67% of us are overweight but we should be eating a diet where almost half of our calories are made up of not vitamins, not minerals, but fat. The statement made me furious but I had absolutely no knowledge to refute his statement except that it just sounded insane.

I left the station that day determined to not find a diet book but a book about nutrition that was based on science.  I looked at the author’s credentials: scientist or m.d.? Was the science related to nutrition?  Next, I looked for references.  Were there references to scientific studies? More than one? Was the author selling more than a book? Like diet food or supplements or services?

The book I ended up going home with was ‘The China Study’ by T. Colin Campbell, PhD in nutritional biochemistry.  The book has 753 references to scientific studies. I was eating only plants by page 73.  Dr. Campbell’s work was so utterly convincing about the health benefits and disease prevention of cutting waaaaaay back on animal protein that it just came together as extremely good timing for me and that is why I eat mostly plants. ‘Mostly’ because I still put butter on my toast and I will always eat whatever my grandma cooks.

Of course this post was about the number 2 question that I always get.  The first? “Where do you get your protein?”  That’s another post, though.

Why a Salad Costs More than a Big Mac

Wednesday, September 22nd, 2010 by Karena

The Cancer Project, a part of The Physician’s Committee for Responsible Medicine, was on the air today with me and my co-host, Crystal Lacey Edwards. Joseph Gonzalez, R.D., answered questions about using nutrition to prevent and even increase survivability of cancer.

The cliff notes? At least 35% of cancers are avoidable by eating well. An additional 55% of cancers are avoidable with improved lifestyles changes: exercising and being actively involved in your life (as opposed to an observer checking off the days until you croak). What you also need to know is that the guidelines that we have all seen for eating to prevent cancer (Eat more fruits, veggies and whole grains while avoiding red meat) actually means to eat only fruits, only veggies, only whole grains and legumes and NO meat if you want to really prevent cancer.  The other guidelines are set up to try and make the change in eating habits more attainable.  Holy cremoleee…::slapping my forehead::  It seems the guidelines are like saying you could drink one glass of water a day and survive but if you actually want to live then 6-8 glasses would be best.  Crazy-ness…

We wrapped the conversation up by asking Joseph why it has become so easy to eat the Standard American Diet (the usual meat and potatoes) and he responded by sending me this link after the show: Why a Salad Costs More than a Big Mac. You can see from the graphic below that the foods receiving the most government subsidies (which means they cost us less at the grocery store) do not match up with the foods recommended in greatest quantity by our federal food pyramid.  Check it out:

The foods most heavily subsidized by our government do not match the foods most highly recommended in our food pyramid

The podcast will be up shortly and I’ll post the link here. In the meantime, go suck on a strawberry.  It could save your life.

T. Colin Campbell, PhD, author of The China Study: The Protein Controversy

Wednesday, July 21st, 2010 by Karena

It was a great privilege to welcome back, T. Colin Campbell, PhD, researcher professor emeritus in biochemical nutrition at Cornell University.

The China Study by T. Colin Campbell, PhD

The China Study by T. Colin Campbell, PhD

On today’s show Dr. Campbell discussed the protein controversy and I greatly encourage you to listen to the entire interview by clicking below. We also discussed how to identify accurate nutrition information with all the conflicting nutrition reports that we see in the media: one days eggs are good for you and the next, they are not.

Dr. Campbell advises to be on the lookout for ‘reductionist’ studies that may not look at the complete nutrition picture. In a reductionist type of study, scientists study one nutrient, say Vitamin C, and see how varying levels of Vitamin C affect a certain disease or condition. We are all used to seeing this type of study in our favorite magazines: how Vitamin D does this and Vitamin E is great for that. Dr. Campbell says that this type of study does not take into account the true complexity of nutrition.

For example, a study might show that Vitamin C, all by itself, has no significant affect on a particular disease or maybe in very, very high quantities it shows a great affect on disease. But Dr. Campbell, argues that what we need to look at is the whole food. When we eat an orange we are getting the Vitamin C but we are also getting another 40 or so nutrients that make the Vitamin C as effective as it is for restoring health and fighting disease. And in a supplement? Well, there is no support for the Vitamin C to create health and to destroy carcinogens; it’s flying solo.

Long story short, Dr. Campbell recommends that when we read nutrition studies that we consider if the study was done on a whole food or supplement. Food is infinitely complex in its ability to fight disease and to restore health. Singularly reduced supplements? Not so much.
