Food & Fasting

I can’t stress enough how important the food you eat, or don’t eat, affects your health and your cancer. Food can be medicine or poison. It is something you have complete control of, when cancer seems to otherwise be hijacking your life.

Eat lots of fresh vegetables, especially fermented ones. Not too much meat, only good quality grass fed organic. Limit or better yet, eliminate sugar. Consume good oils like fish, coconut, olive oil and hearty bone broths. Try fasting.

A lot of this stuff is considered complimentary or alternative medicine, which is starting to get more recognized in the medical field through integrative medicine. It is important to understand that there is a whole lot of unsupported, out right quackery when it comes to miracle cures for cancer. Be skeptical and be cautious.

Believe me. You will get all sorts of advice from well-meaning people and a lot of it will be worthless.

The American Cancer Society has a good read on this topic, and the Mayo Clinic too.

The book Anti-Cancer: A New Way of Life had lots of awesome info in it, and I would recommend this highly to everyone.

Food Choices

florida-summer-herbs-n-veg.jpgI would highly recommend following the paleo style of eating. Not just for cancer fighting purposes but for overall good health. There is a lot of evidence now pointing to the ill effects of consuming grains (pastas, breads, rice, corn etc.), sugars and all sorts of processed foods.

It can be a challenge to start because it initially goes against what we’ve always thought to be true; that whole grains are good for you and that a low fat diet is the way to go.  I can say personally and from testimonials of several people I know, that everyone feels better, and has more energy. For a good starting point and continued education I would recommend the “Marks Daily Apple” blog, and his “Primal Blueprint” to get started.

Basically if you can make your diet consist of meat (good, grass-fed, organic), lots of vegetables, good fats and limited amounts of nuts, fruit you’ll be good. Ditch the sugar (cakes, cookies, granola bars –really read the labels there is more sugar in those things than you’d think, its appalling!), processed foods, and very limited or no rice, beans etc. The reasoning behind all this can be found on the website listed above.

As a science-minded skeptic, I have to admit that I was very reluctant at first to start eating this way. However, there is evidence to support it, and it just makes common sense to avoid sugary, processed junk. Personally, I feel much better when I eat cleanly like this, because the diet reduces inflammation which is basically a cancer growth support network.

I really can’t emphasize enough the importance of eating this way throughout the rest of your life as a way to stay optimally healthy. Not just when cancer or some other awful health thing shows up. This is a lifestyle.

Here’s some stuff on “Eat to Defeat Cancer”, and also a TED Talk on the subject.  This isn’t necessarily paleo but has similar undertones of eating things that will help you stay healthy and fight disease.

Basically, eat LOTS of vegetables all the time, especially dark leafy greens. Find ways to include ginger, turmeric, garlic and green tea into your diet however you can. There is good evidence of their cancer fighting abilities, but we just never seem to consume them enough. I make a really great “chai” type tea by simmering fresh turmeric and ginger, cinnamon, allspice, vanilla into a concentrate. Then I heat it up later and dilute with water. You can add milk/cream, honey to taste. Yummy!

Here is a document with turmeric recipes, from a class I taught with Susan a few years ago. I personally love curries so make them a lot using garlic, ginger and turmeric. If you can, use fresh turmeric, ginger and garlic. Living in Florida, I’m lucky that I can grow some of these, so I know exactly how fresh and clean they are! Eating them fresh, not cooked is probably better. We know for garlic that when cooked, the powerful phytochemicals are lost.

Investing in a good blender like a Vitamix will allow you to pulverize vegetables into smoothies. When I wasn’t feeling well, or even when I was but wanted something nutritious quickly, I would blend up some smoothies. The Vitamix will let you liquefy whole beets, carrots etc. The trick is reducing the sweetness, with about a 4:1 ratio of veg: fruit. This can take some time getting used to, so gradually ease the sweetness down and consider using super healthy fruits like blueberries or blackberries. Be aware, blended fruits and vegetables do flood the liver quickly with sugar so I wouldn’t do these all the time, and take care to keep them as unsweet as possible.

Here is a document that a good friend and trusted herbalist and wellness expert Susan put together for me. It outlines some foods and supplements to try.

Fermented Foods

Now this is where vegetables get really powerful!! The process of fermenting vegetables not only preserves them, but increases their nutritional value, makes them more digestible and full of anti-oxidants. They are loaded with probiotics too. There is a lot to say on these tasty bacteria we’re eating and their benefits. Read here from Science-Based Medicine a comprehensive review about various fermented foods and their benefits.

I teach a fermentation workshop twice a year with three other women I call the “Queens of Fermentation”. Here is our class hand out with recipes!

Sandor Katz is the fermentation guru and any of his books will get you started on fermentation. I own two of them, my favorite is Wild Fermentation.

Fasting has been an ancient ritual for many cultures, has been attributed to longevity, and was something our ancestors endured out of necessity and for religious reasons. Today, the thought of withholding food seems crazy to people. No one deliberately goes hungry, we hate the sensation of hunger and often exclaim, “I’m STARVING!” When it’s only been a few hours since we last ate! Our bodies never get a break from metabolizing food, and many of us are forcing our bodies to process food it doesn’t want. So we work harder to process, store and eliminate. Our bodies deserve rest and a little TLC!

I have come to think about fasting as a reset button. Like whenever your computer or phone goes wonky, the first thing you do is restart it. Same with the body and the gut.

As I was researching complementary care for cancer treatments, I stumbled across some interesting papers on fasting during chemo by Valter Longo of the University of Southern California. The premise is that cancer cells consume lots of glucose (sugar) during their metabolism and growth. When they are cut off from sugars (i.e. during a prolonged fasted state), they switch metabolic pathways which ends up producing free radicals that kill the cells. The other significant factor is that normal cells go into protective mode during a fasted state (about 48 hours or more), repairing themselves, triggering cell death for damaged cells, and somehow protecting themselves from the effects of toxins (i.e. chemo).

The 1-2 punch for cancer is this: in a fasted state prior to, and during chemo infusions, cancer cells are already stressed from lack of glucose, are more prone to the chemo, AND your normal cells are spared some of the abuse. This study reviews human clinical trials, where most patients report far less side-effects from chemo when they were in a fasted condition.

Remember this is not just for cancer fighting, but for its prevention and overall health. It’s a powerful tool to continue to use throughout your life.

I found it to be easy to do and think it helped with the nausea and maybe even the efficacy of the drugs. The concept is that your body’s normal cells are evolved to endure caloric restriction. We didn’t evolve eating three full meals a day, every day after all,  so they go into repair and maintenance mode when starved. In this condition they are able to resist some of the penetration of the drug, so they are somewhat more safe, while the cancer is not. Of course the chemo will still affect you, but supposedly less.

Some cancer treatments may require food, and a friend going through treatment informed me that turmeric actually messes with radiology scans! So just know your situation and decide what’s best for you. I had a friend who was so sick and weak from her treatments, she couldn’t possibly consider fasting because she needed some calories to keep her going. Although I desperately wished she would have tried it, she knew it wasn’t for her.

Depending on how long you are in a fasted state, your immune system gets an entire re-boot. This seems to be around the 72 hour mark. Our immune systems are responsible for detecting invaders like viruses and infection and helping get rid of them. Cancer often sneaks in undetected, but giving yourself an immune re-boot gives the new and fresh system a second chance to recognize the invader and attack.

A fairly quick and easy fast that lasts 18 hours, simply involves not eating after dinner, and skipping breakfast.  For me this is an easy one because I’m not typically hungry in the morning anyway. By the time lunch rolls around you’ve done a mini fast!  Or you can up your game and go a full 24-48 hours to really start stressing out the cancer and cleaning up the other crap in your body.  I don’t know if anyone knows how much, or how often you need to do it, so just do it. Don’t wait for a specific formula.

I can promise you that if you eat more paleo, the higher fat and protein content are very satiating, making fasting less difficult.  I remember trying to fast when I was younger for a fundraiser. Grains and sugars were a regular part of my diet, and I felt so hungry, so quickly that it was exceedingly difficult to go a full 24 hours.  I really did feel like I was starving.

This is as much a mental exercise as it is physical. Remember, you are NOT starving, you are performing a healing ritual that will be over soon. Hunger comes in waves and will dissipate. Drink lots of water or herbal teas and try not to dwell on it.

If you are going for a longer one, consider what your schedule is. Try not to do anything too physical or mind-boggling towards the end when you’ll be feeling…loopy and euphoric! Skies are brighter and music more sweet when you’re in this stage. Try to enjoy it!

How I Fasted During Chemo

I was convinced enough to try it and will admit that I didn’t tell my doctor. I know you are supposed to divulge everything, but I didn’t think this conflicted with my treatment and I didn’t want to be talked out of it. I have the utmost respect for oncologists and their knowledge, however I also realized early on that the holistic view of the disease and the person were not considered. Cancer treatment is very tunnel vision in Western medicine, so I was certain he would tell me to not do it. Given what I’d read about fasting, it wasn’t anything to be worried about in my condition of being young, and very healthy other than the pesky cancer thing.

What always irritated the hek out of me, was hearing from doctors, nurses and everybody to just eat what I felt like eating to make sure I had calories! I’d see patients in the waiting room eating and drinking junk food and I wanted to scream! OK so if I really just felt like eating jello and candy, that was preferable? Trust me, I totally get how treatment makes you adverse to certain foods, your taste buds change, and your nausea dictates what you can tolerate. But if junk is what you can tolerate, then I’d argue to just not eat until you feel a bit better.


For each and every chemo treatment, I fasted prior to, and during the infusions for a total fast time of about 2 days. No food 24 hours before chemo, no food on chemo day, then the next morning I’d ease back in. Eat small amounts of food to ease back in, like miso soup with bone broth. Since I did this every time, I have no control for comparison, but I will say that I tolerated chemo fairly well, all things considered.

Yes, I was nauseous and it required meds to stop me from hurling all over. Yes I lost my hair and felt more exhausted as treatments wore on. But I was still incredibly active. I would drag myself off the couch and get to the farm, sitting out in the hot sun weeding and picking flowers! I still went out and visited friends and family and did social things. I flew to Canada to see family and spent time camping, boating, and sightseeing with my sister Annette and Mike in Quebec after my last treatment was completed. So it’s possible the fasting helped alleviate the side effects, if my normal cells were offered some protection from the toxic drugs. I don’t know for sure, I can only speculate.

Hairless and happy with girl friends Anna and Val, fishing on the coast. Chemo didn’t stop me, and I think fasting and good eating were supportive enough to keep me moving.

My thoughts on this now, post cancer with 4.5 years (!!!)  in remission now, is that fasting is a powerful physical and spiritual practice. The physical effects on the body of fasting are incredibly beneficial for overall health. The very act of enduring it is challenging, but when it’s done with intention it is exhilarating. To purposefully withhold nutrition for a short time is difficult, and one must overcome the temptations, and remember the why.

I continue to fast to this day. Some days I just withhold eating for several hours by skipping a couple of meals. This comes easy some days if I’m not all that hungry, or am kept busy at something and I don’t think about eating. These mini fasts occur throughout the year and average perhaps once a month. They’re simple. If I skip breakfast and lunch, I’ve gone 24 hours. Once or twice a year I do the full re-boot of a 48-72 hour fast. A recent paper suggested the 72 hour time frame was when the immune system was fully refreshed and a deep “cleanse” occurs. I have a good friend with a complicated immune disease, so we embark together because not eating for that long is hard, and we need support!

It’s easy to overlook the fact that so much of our lives centers around food. Particularly because I am so obsessed with food! I grow some of my own, and have farmers, gardeners and foodie friends! My career is local food! So, when I go for the big fast with my friend JulieAnne, we look at our calendars and pick a good time; conscious of what we’re doing those days in terms of our energy and focus levels, and what temptations may arise! But it’s worth the endurance, because it feels great and you know what is happening at the cellular level to re-boot the body.

Here is a post about fasting, that includes a great mini documentary explaining it well.

Scientific Articles about Fasting

These may be a little dense reading, but worth the look to understand more about the research behind all this stuff.

Fasting and Clinical Applications

Not exactly about fasting, but an interesting look at metabolic defects of cancer cells, particularly sarcomas that can be exploited and cause tumors to die, without having to use typical cancer drugs. 

Sugar and Cancer

There is increasing evidence that sugar (fructose/glucose) fuels cancer cell growth. Cancer cells hyperactively gobble up sugars at a far higher rate than normal cells, allowing their proliferation. While our normal cells also need sugar to function, they typically get way too much in the standard American diet, causing the metabolized sugar to turn to fat, which over time can lead to any number of obesity-related health concerns.

“Sugar should be thought of, like cigarettes and alcohol, as something that’s killing us.”

~Robert Lustig, American Pediatric Endocrinologist

One of the best things you can do is to ditch sugar NOW!! It is difficult to break this drug addiction, but once you get over the initial withdrawal, its gets easier. I have always had a major sweet tooth and found this part really hard. But the scare of cancer was enough.

My experience is that people say, “oh I really don’t eat that much sugar”. But if you start writing down what you eat on a daily basis, and consider that many high carb and starchy foods like bread, pasta and potatoes are converted to sugar quickly in the body, you will discover that you are consuming a lot of sugar.

Even if it didn’t fuel cancer growth, consider the ill effects it can have on overall health in general.

While I believe eating a whole foods diet supplies most of what you need, there are some wonderful herbal supplements that have clinical evidence for helping in the fight against cancer. Two trusted friends, one a medical doctor and the other an herbalist have compiled this list for me.



I’ve included a scanned copy of a document my mother in law gave me. And if you’re skeptical, read this journal abstract from the National Institutes of Health.  I was told however that you must be sure you have the correct brand as they are not all pure. The brand I have is supposed to be the best and you can get it the cheapest online from Vitacost. Be sure it’s this one from the Allergy Research Group.


Astragalus root may be beneficial fighting cancer, and also may reduce nausea and vomiting associated  with chemotherapy.

Dandelion Tea

I recently stumbled across this article about dandelion tea and cancer. Some researchers in Canada are currently studying its effects due to intriguing evidence of its cancer fighting properties. You can buy tea bags of it from natural stores, or get it in bulk and brew your own tea. It’s the roasted roots of the plant and I quite like the taste of it. Make 2 or more cups a day.

Fish Oil

An important component of our daily fight to reduce inflammation. Omega 3 fatty acids (EPA and DHA) in fish oil help to restore the balance between pro-inflammatory and anti-inflammatory chemicals in the body without adversely affecting immune function.


Need to put more info here.

Green Tea

Green tea may inhibit the development of new blood vessels that feed tumors. You need to drink a lot to realize the benefits, about 5-10 cups per day. But I’d hypothesize that daily consumption of a cup or two as a long term preventative would be effective.

Milk Thistle

This is used for liver support during chemotherapy which can wreak havoc on many of the body’s tissues, including the liver. It may also have direct effects against liver cancers.

Mushroom Extracts

Mushrooms can protect agains the side effects of radiation therapy and improve survival with cancer. There are many kinds and you can get in liquid or tablet form if whole mushroom is not available. Shiiitake, maitake and reishi are good. My friend Michael gave me some foraged reishi and turkey tail and I admit they taste awful! I had trouble using them, but sucked back mushroom tea like a bitter medicine, gritting my teeth. There may be better ways to take them!


Need to put more info here, in the meantime here is a document from a class I taught about turmeric, including some recipes! A few quick notes: eat it raw if you can, make sure you have it with a few shakes of freshly ground black pepper and some oil. The pepper-turmeric combo is far more powerful and makes the cucurmin more readily absorbed by your body. They go well together too!

Vitamin D

Most people are low in vitamin D. Here in the sunshine state we’re a little less at risk. It might be worth having your blood levels checked, and certainly consider taking a supplement or seeking out food sources that are high.
