I’m sure you’ve all heard the famous Hippocrates quote, Let food be thy medicine and medicine be thy food. He uttered those words in 400-something BC. Back in the day when food was actually—surprise—real food. That meant lots of plants and an occasional animal snack, but certainly not double-deep-fried, nacho-flavored, cheese-like chips; high-fat “Sunday” bacon; or 2-pound cinnamon rolls. When Hippocrates was talking about food as medicine, he was talking about plants. Whole foods.
See those scrawny little scallions in the above photo? Nothing all that special. They’re just onions, right? Well, those onions pack a powerful punch when it comes to health-promoting goodness.
I’ve been doing some research on foods that fight cancer, sometimes referred to as chemopreventive (or chemoprotective) foods and ran across an interesting, recently released (last week) study.
But first, a little background. The term chemopreventive was coined in the late 1970s and refers to the phytochemicals (plant chemicals) in natural products (fruits, vegetables, herbs, spices) that reduce the risk of disease. I mentioned Hippocrates because I figured most of you have probably heard the food as medicine quote. Here’s another similar, although more wordy, quote from a March 2010 Pharmaceutical Research Journal abstract on cancer chemoprevention.
Moreover, it has been recognized that single agents may not always be sufficient to provide chemopreventive efficacy, and, therefore, the new concept of combination chemoprevention by multiple agents or by the consumption of “whole foods” has become an increasingly attractive area of study.
Hmmm? Wow, the “new” concept of consuming whole foods as medicine? An “increasingly attractive area of study.” Very interesting (I say with a touch of sarcasm). Wasn’t Hippocrates the father of modern medicine? Back in 400-something BC?
Okay, so we’ve gone astray on many fronts when it comes to health and what we eat. I’ll save that rant for another day and get on with the exciting news about scallions, one of my favorite foods.
There’s an increased risk of intestinal cancers associated with celiac disease. The risk is small and if you’re on a seriously committed and healthy gluten-free diet (think whole foods), the increased risk is minimal. I’m not losing any sleep over it. But colon cancer is one of the most common forms of cancers in the general population, so it’s nothing to sneeze at.
What do scallions have to do with intestinal diseases and colon cancer? Well, according to a new study, scallion extract (scallions soaked in hot or cold water) suppressed key inflammatory markers and reduced the size of cancer tumors. Yes, in rats, but in some ways, we’re not all that different.
In summary, directly from the study: “We therefore suggest that scallion plant materials and their extracts may have the potential to be systematically developed as a chemopreventive agent(s) or medicinal food against specific colon cancers.”
Psst—you don’t have to wait until they’re “systematically developed.”
I say, load up on fresh, organic scallions right now. Chop them and add them to soups, stews, chili, whatever you can think of. Both the hot and cold extracts provided protection, but the hot (cooked) version topped the list. Sauté them and add them to raw salads. I do that all the time and they taste spectacular! Roast them in a medley of vegetables. Slice them length-wise and put them on pizza (check out this recipe: my new favorite pizza topping to see what I mean).
Here’s the good news about this study. It didn’t take much, just one scallion a day to provide the extra boost in protection. If that’s not enough, scallions impair genes that store fat. Yes! Okay, in obese rats, but still. Good news, don’t you think? Onions also help lower blood pressure and are anti-inflammatory.
What’s not to like about the scallion?!
Go, buy some now! Let food be thy medicine!
PS Stay tuned for a roasted scallion pesto recipe. Oh my gosh! Delicious.

One more post on weight loss (or gain), mitochondria density, and metabolic health and then I’ll get back to posting some healthy, gluten-free recipes. I promise. But before I do that, I have to fill in the blanks from my prior post on this subject. To catch up, please see part one—the mitochondria: your own starship enterprise. This two-part series features highlights from last June’s Fitness & Health Bloggers Conference held at the newly opened Anschutz Health & Wellness Center.
Okay, are you ready for a different take on weight loss? Curious, even?
Dr. Iñigo San Millán is the director of the Human Performance Lab at the Anschutz Center. He’s an exercise physiologist and his conference presentation brought together two different areas of customized approaches to fitness. On one end, we have the average person trying to lose weight and get healthy. On the other end, we have world-class, elite, endurance athletes. You know—the kind of people who run ultra-marathons, break world records, win Olympic medals, ride in the Tour de France. Yes, I know, there’s a big gap between average and elite. But according to Dr. San Millán, we have a lot to learn from elite athletes and can apply the same general principles of metabolic health to our own pursuit of fitness.
What is metabolic health, you ask? Overall, it means being healthy and fit in all aspects and on a whole body level (on a cardiovascular, hormonal, emotional, nutritional, and cellular level). Sounds rather yogic, doesn’t it? Mind, body, and spirit health.
Dr. San Millán tossed out some brutal facts about the rising rates of obesity, diabetes, cancer, and cardiovascular disease in the United States. Sixty-eight to seventy percent of the US population is overweight or obese. Two-thirds of Americans are on some sort of diet or weight-loss program at any given time, but 98% of weight loss is gained back. That roller-coaster ride of weight gain, weight loss, weight gain undermines metabolic health and makes it increasingly harder to lose the weight. What’s the answer?
It’s complicated and there’s no magic formula, but there’s a positive side to this. We can make health-enhancing changes at anytime of life. It’s never too late to eat better and move more. BUT, it has to become a way of life, not a temporary “diet” or periodic exercise program.
According to Dr. San Millán, elite endurance athletes are the most fit people on the planet and the only population totally free of acquired metabolic and cardiovascular disease. As Dr. San Millán said in his talk, “Simply, it doesn’t exist.”
So, what makes these elite athletes metabolic super-stars?
High mitochondrial density and metabolic flexibility.
In a nutshell: cellular energy requirements control how many mitochondria we have (in “healthy” individuals without a genetic mitochondrial disorder). The more we move (walk, run, hike, bike, ski, play tennis), the more mitochondria we have. Endurance athletes have twice the mitochondrial content as sedentary individuals (Davis et al., 1981, 1982). The more mitochondria we have, the more efficiently we process carbs and fat. The more efficiently we process carbs and fat, the less likely we are to be overweight. If we maintain a healthy weight, there is less risk of insulin resistance, diabetes, and heart disease.
See those legs in the above cycling photo? That’s turbo-charged mitochondrial density in action. It’s unlikely any of those cyclists are overweight or have type 2 diabetes or heart disease. Tour de France riders consume an average of 6000–9000 calories per day. Of those, 75–80% are carbs. Michael Phelps told ESPN that he consumes 8000–10000 calories per day during training and competition. Again, a high percentage are carbs.
Okay, sounds good, but where do we start? And comparing ourselves to elite athletes is a little intimidating, wouldn’t you agree? I don’t know about you, but I’m not going to be running marathons anytime soon. Plus, we’re all different. Each body is unique. We have different adaptations to exercise and different responses to what we eat. But, the good news is, it doesn’t matter how old we are or what shape we’re in, we can make positive changes. We can lose weight. We can eat better. We can become healthier. We can increase our mitochondria and enhance our ability to process carbs and fat. We can thrive.
Here’s the deal. According to Dr. San Millán, physical activity should be the foundation, boosted by a healthy diet. And that healthy diet can include carbs. Healthy carbs aren’t evil, we just need to move our bodies daily to be efficient at processing those carbs.
I agree. We need to make time for activity, at least an hour a day, more if possible. You don’t have to go to the gym or buy expensive equipment. Dance, do yoga, garden, walk your dog, sell your car, move to Paris, become Amish. It’s about permanent lifestyle changes; it’s not about dieting. We need to move more to lose weight, maintain metabolic health, and avoid type 2 diabetes and heart disease.
We don’t have to be an elite athlete, but we can learn from them.
Peace, love, and physical activity! Lots of it. Weight loss will be the side effect!

Last year around this time, Venus Williams dropped out of the U.S. Open and revealed that she was suffering from Sjögren’s syndrome, a chronic autoimmune disorder. Yesterday, the 7-time Grand Slam champion made another early exit from the US Open with a dramatic loss to sixth-seeded Angelique Kerber.
I started this blog (Gluten-Free For Good) in 2007, mainly to increase awareness of celiac disease and help people thrive on the GF diet. Not just get by, but to live active, radiant, and healthy lives. Today’s post was supposed to be part #2 of a series on mitochondria density, elite athletes, weight loss, and exercise, but I decided to put that one on hold to focus on Venus and Sjögren’s.
Hey, did I just hear a collective sigh of relief? I promise, you’ll find the whole mitochondria density thing and weight loss interesting once I get to it.
Okay, some of you will find it interesting.
A few of you?
Anyway, back to Venus, Sjögren’s syndrome, and … gluten.
Sjögren’s is a systemic autoimmune disease in which a person’s white blood cells mistakenly attack their moisture-producing glands causing serious complications throughout the body. Dry eyes and dry mouth are distinct features of the disease, but chronic fatigue, joint and muscle pain, gastrointestinal problems, heartburn, reflux, esophagitis, neurological problems, brain fog, peripheral neuropathy (numbness and tingling in the extremities), abnormal liver function, pancreatic disorders, and Raynaud’s disease (among others) can also be present. Women are disproportionately affected with Sjögren’s (9:1).
Sjögren’s is a red flag for celiac disease. It frequently occurs in the presence of another autoimmune disease, often connective tissue disorders like rheumatoid arthritis or lupus. Many of these autoimmune diseases sound like versions of the same thing, with just a few variations. Each condition typically has a few hallmark features, but so many of the symptoms are similar. Autoimmune diseases hang around together.
The gluten-free diet is the medical protocol for celiac disease. Why not for all autoimmune diseases? Gluten causes inflammation. Decreasing inflammation via diet and lifestyle should be the first step in reducing the impact of the disease, so it makes sense to eliminate gluten.
Apparently Venus is on a vegan diet to combat her symptoms. There are rumors she’s dabbling in the gluten-free diet as well.
Go for it, Venus! Eliminate gluten FOREVER.
What are your thoughts? Do any of you have Sjögren’s and celiac disease? Should everyone with autoimmune complications, regardless of what they are, be on a nutrient-dense, whole-foods, gluten-free, dairy-free diet?
That’s my opinion.
Are any of you BFFs with Venus? Her current boyfriend? Sister Serena?
I’d love to send her a copy of our (co-written with friend, colleague, and endurance athlete Peter Bronski of No Gluten, No Problem) newly released book The Gluten-Free Edge: A Nutrition and Training Guide for Peak Athletic Performance and an Active Gluten-Free Life. Tip me off if you know Venus. I’ll send her (and you) a copy of the book.
Peace, love, and gluten-free power serves. (Not that I have a clue about powerful serves. Dink, dink.)
