Nutrition and Colorectal Cancer
I've recently listened to #346, your interview with Dr. Kathryn Bradbury on nutrition and colorectal cancer. I found this useful and informative, so thanks very much for that! But I have a question for you based on this episode... I already have colorectal cancer, Stage 4, in fact. It started, not surprisingly, in my colon, and was dealt with via a combination of radiation, surgery, and chemotherapy. Approximately 10 months after my chemo was done, it showed up in my lungs, both of them. I was lucky, for a certain personalized definition of lucky, as it was deemed operable and I had two surgeries in the first quarter of last year to remove the cancer from both lungs. I've now gone about 14 months since my second lung surgery, am feeling great, and as of mid-March of this year have no evidence of cancer in me. So here's my question - given that the cancer is (or was...?) already in me, and given that there seems to be decent evidence that dietary choices can reduce the probability of it arising in the first place, is there any evidence that I can do anything nutrition-wise to minimize the chances of it returning again, spreading further, etc.? I've done some digging but haven't been able to find anything that I understand well enough to act on. Thanks again and as always for your great work! Mike (p.s. I've lost count of the number of people who've laid the "carbs feed cancer" stuff on me in the past few years! Fortunately, this is one I've been able to figure out by myself.)
Protein status
Would you please share your opinion about how you evaluate protein status in the body? Do you consider serum proteins (albumin etc) as a reliable indicators of protein sufficiency/ insufficiency in the diet, or indicators that people absorb all the protein they consume? Or amino acids profile would better indicate the protein status? Thank you
Visual muscle size differences in plant-based athletes
Hi Sigma team. I'm a coach of a combat sport. Subsequently, I am very aware of my students' weights. Anecdotally, I have noticed a trend in my plant-based students that, when compared to students eating non plant-based diets, there appears an obvious visual difference in muscle sizes (smaller/not as pronounced in plant-based) in individuals of the same weight and approximate height/dimensions. This difference only seems visual, there does not appear to be differences in strength, power, speed etc. Has this been tested/documented/researched anywhere? While I acknowledge these observations might simply be a confirmation bias of mine, if true what might explain this phenomenon? Thanks, Steve.
