Sugar and Cancer: An Excerpt From Ravenous

3

“'Too much sugar' might be the simplest explanation for the many obesity-linked cancers, but it is not a simple explanation. It is an idea built upon more than a century of science," Sam Apple explains in this excerpt from Ravenous: Otto Warburg, the Nazis, and the Search for the Cancer-Diet Connection. Here, Apple highlights key moments in that century of science, focusing specifically on how sugar and other rapidly digested carbohydrates spike insulin and insulin, in turn, "activates the pathways linked to cancer."

Commented on: Sugar and Cancer: An Excerpt From Ravenous

I look forward to reading this. Even most of us working in the field are not sure what is true, what is conjecture and what is just the rationale in our grant application. It is common to read (or write) that one can’t say “cancer.” Even a single tumor in a single organ may have several cancerous cells. And they may interact. 


An additional complication may be the role of sugar. The excerpt begins with an appropriate disclaimer “Sugar is not the entire story of insulin resistance. Any carbohydrate that is rapidly digested…will also spike glucose and insulin levels.”  Understanding the cancer-diet connection requires awareness of how sugar is an easy target and that that has allowed traditional medicine to avoid facing the benefits of overall carbohydrate restriction. The circumspection doesn’t last long: “ nothing appears to drive the first stages of the process quite like refined sugar. Drinking sugar—in soda or fruit juice—is thought to be worst of all.” Given that any sugar, that is, sucrose, is not nearly as effective at spiking glucose and insulin levels suggests that this is likely an exaggeration. Precision of language is important. While Cantley’s experiment with high fructose corn syrup in mice (Science (2019) 363): 1345–1349) is elegant and compelling, I don’t think we can easily generalize. And the diabetes connection is fundamental in metabolic theories of cancer. Despite Richard Johnson’s impressive work in bringing out unique aspects of fructose metabolism he agrees that, in diabetes, glucose is more important than fructose (personal communication). It is likely premature to follow Gary Taubes’s idea that “sugar can be thought of as ‘a primary cause’ of cancer.” The risk is that it will perpetuate the medical tradition of downplaying the importance of low-carbohydrate and ketogenic diets which has been, in my view, so stultifying in nutritional science. Sugar, that is, sucrose or HFCS, is a carbohydrate. Carbohydrate is what is left after Occam’s razor. 


So, I expect to learn from this book but I hope there is been adequate attention to dangers in tackling a controversial subject.

Practiced triples and was able to string 2 together a few times. Went with doubles in the workout though.


21-18-15-12-9-6-3 reps for time of:

Double-unders x2

Stationary bike (calories)


I doubled the doubler under reps, so 42-36-30-etc, on carpet with no shoes.


Stationary bike was clip-in only. About 2-3 minutes were spent putting shoes on during transitions.

I started to figure out the DUs late in the round of 15. Early rounds I did maybe 1 or 2 at a time; later rounds up to 6 or 7 consecutive. I had to learn to jump REALLY high and REALLY straight, and then I could get a few in a row with that horrible rope that's better suited to hanging than jumping.

Commented on: Sugar and Cancer: An Excerpt From Ravenous

I comment this not particularly for this article, but in general on this topic. I like all those low-carb theories. They make so much sense. But then again fats and proteins elevate insulin too. And insulin also helps building muscle. So, what if the truth is somewhere in between? Like “eat to support activity, not

fat” or “cut proceed foods” or “eat meat, vegetables, nuts, seeds etc.”. Sugar helps cancer cells to grow. Ok. Iron does too. But does it make iron bad? Not really, but the WHO now says red meat is cancerogenic, duh. I wish there would be more consent between low-carb and calorie in calorie out people. The two principles don't actually exclude each other. I think the science field could go on faster without the battle one against the other. And without demonizing any particular food. If you have a really high caloric need, pro-athletes as an exemple, it's hard to fuel those with meats and vegetables. They would be full before taking in enough calories. And when you live of soda, but don't meet your caloric need (theoretical possible) I doubt cancer cells would grow in a caloric deficid.


I really think CrossFit does a great job with its food recommendations in the training guide. But sometimes I think the articles on crossfit.com are somehow based on low-carb/keto and therefore neglect the points of caloric balance. (and I know the articels that not every calorie is the same. Still). Again, I don't think one exclude the other. Change my mind.

Thomas,

I suspect that you don't know that your comment is dismissive and that, like many critics of carbohydrate restriction, you seem to think that we have been waiting for you to straighten us out. After all, you like all those low-carb theories but you think somebody (all low-carb researchers? me?) are too doctrinaire. I really don’t think many people think that calories don’t count. I am not even sure that everybody believe that sugar makes all cancers grow. You’re right about the battle, though, and dialing back would be desirable but it comes from people creating straw-men to attack. You could actually ask any low-carb researcher what they believe. We are friendly folk. I can’t speak for everybody but my own book [1] has as the first principle that “If you’re ok, you’re ok,” that is, not everybody has to be on any particular diet.


On the other hand, the relation of diabetes to cancer is important and I have organized and presented the work of 25 researchers and clinicians that provides 12 points of evidence that carbohydrate restriction is the first approach for treating diabetes — not the only, or the best for everybody — the most supported by the science [2]. One of the points of evidence is that calories-in-calories-out is not the best idea. So, what truth is in-between the best approach and lesser approaches? Sometimes, it turns out to be high-priced drugs with side-effects. In any case, the Virta group and others have provided the most compelling evidence that moderate diets give moderate results [3-5].  


But about the battle. If there is a meeting of the different points of view, it must come from the majority, established organizations, AMA, ADA, NIH and individual researchers who are unrestrained in resistance to carbohydrate restriction. Check out the current iconic attack from Harvard School of Public Health, Seidelmann, et al. [6], who finds that low-carb diets will increase all cause mortality, never mind that no low-carb diets were studied. You can probably find many critiques. I recommend the April 1 news alert on my blog [7].  And beyond the literature, you might Google the names of the physicians and health providers who have been personally and professionally attacked for recommending low-carbohydrate diets for their patients or even tweeting an opinion that they might be good —  Jennifer Elliott, Tim Noakes, Annika Dahlqvist, Gary Fettke among others — I offer an ironic take on it on my blog [8]. 


So I am not even sure what is on your mind or what would change it. By coincidence, I got into this field because of my interest in calorie balance. You “know the articles that not every calorie is the same. Still.” Still, what? Still you don’t have to read my book?


So, I am sure you are surprised that I am giving you such a hard time. I am sure that, like most of us, you would like to see a reduction in the adversarial, even hostile environment in nutrition but, in these matters, you have to go to the people in power, the people who control the granting agencies and the publication industry.

Champions Club Scaling Notes


RANT

Let me tell you about biking. I walked to high school every day, and now as a business owner I've walked to the gym every day for the last 11 years. So when Marathon Matt asked me to ride a bike alongside him while he ran one of his 20 mile workouts I came to the realization that I had not sat my butt on a bike seat probably since 5th grade. You know the saying, "It's like riding a bike"? Well... it's kinda true. After like a minute I got the feeling back and the ride went really smooth. Until it didn't. About two hours into this little adventure I temporarily forgot how to use the handbrake and instead of running over our gym's favorite marathoner I decided to steer my bike into the side trail and wiped out. I have never felt so unathletic in my life. That concludes all I wanted to tell you about biking. I realize this information brings nothing of value or relevance to this workout.


WORKOUT FORMAT

Using fatigue (cardio/endurance and stamina) to challenge our accuracy, specifically with jumping


MAIN DECISION

Do I want to test my jumping today or do I want to practice my jumping today?


TECHNIQUE SCALE

Rest as needed between each round


CONSISTENCY SCALE

AMRAP in 15 minutes of:

Bike some amount of time

75 singles/30 double unders (or 15 touch-and-go box jumps)

*jump rope/box jump reps must be unbroken


INTENSITY SCALE

As is, sub touch-and-go box jumps for triple unders


INJURY SCALE

Lower-body - see if you can use fatigue to challenge the accuracy of a handstand or some other upper-body movement. So one movement that makes you breathe heavy and one accuracy movement of your choice. Throw something together that lasts for about 15 minutes


MY STUFF

I did 60-50-40-30-20-10 of double unders and mountain climbers; forgot my time, maybe 11 and some change


GENERAL FEAR LEVEL: 5, although I don't have a bike nor a plural amount of triple under jump ropes, so I'm not the best judge on this one
