Howard, I applaud you for co-authoring the book Proteinaholic and approaching the Super Human Radio interview with a combination of open-mindedness, thoughtfulness, and skepticism. You were a joy to listen to and I believe that we need more individuals such as yourself promoting the diversity of thought that Proteinaholic brings to light. While the bulk of this letter addresses certain topics that we do not see eye-to-eye on, I want to start by highlighting the numerous points of agreement that were brought up throughout the hour interview. The irony with these, of course, is that they have little to nothing to do with protein. 1)      All humans in the world are the same species and we will therefore have a fundamental dietary pattern that best suits our needs. At the core, this will be a whole-foods, plant-based diet without all the processed crap (can I say that on here?). 2)      The...

I've identified with being strong for a very long time now. With the tear of my left tricep and needing surgery I find myself with my first real training layoff. Even when I tore the two attachments of my left hamstring I continued to train push and pull movements. The last time I took off.. I mean really off.. where I didn't touch a weight for an extended period of time was 2005. So I find myself contemplating a layoff. I think I need one too (funny how that is). This won't be easy because training has filled an important part of my day for close to two decades now. I never realized how much bandwidth it occupied on a daily basis till right now. I've spent so much time thinking about the next training session, looking back on the training session that last occurred, building my day to leverage my...

Short and sweet. Two groups of children in daycare environments. One received a fermented milk product twice a day for 3 months. The other received a control drink. 300 children in the fermented milk group. A target probiotic of the Lactobacillus genus was observed for its possible actions in preventing respiratory and gastro-intestinal common infectious diseases. Of the two groups, controls and fermented milk drinkers, the only significant difference was the fermented dairy drinkers appeared to be resistant to the common cold - rhinopharyngitis. The authors concluded “Although no other significant differences were shown between the fermented milk and control product groups in this study, lower incidence of rhinopharyngitis may indicate a beneficial effect of this fermented milk product.” So probiotics and fermented dairy products may be living up to the task of preventing the common cold in children in a daycare setting so all the parents out there.   Source: ...

A new study by an international team of scientists from Germany and the US (Endesfelder. 2016 | click here to read the study) appears to finally provide a mechanistic explanation for the previously postulated and epidemiologically observed link between a messed up gastrointestinal microbiome and the development of anti-islet cell autoimmunity (Brown. 2011; Giongo. 2011), i.e. the self-destruction of your pancreas. Here's what the scientists did Even though it is long-standing knowledge that "the development of anti-islet cell autoimmunity precedes clinical type 1 diabetes" and that the first signs of this rapidly accelerating process occur "very early in life," (Endesfelder. 2016) a mechanism to explain between the beginning self-destruction of the pancreas and the composition of the gut microbiome has yet been absent. To elucidate this mechanism, Endesfelder et al. developed a new approach to the analysis of the microbiome on an aggregation level between a single microbial taxon and classical...

All too often a visit to the doctors comes away with a new prescription to address some attained disorder. The conversation goes something like this: Physician: “Your blood sugar is higher than I’d like to see it. It’s continued to rise over the past several months and it’s now in a range that I think we need to get it under control using (insert drug of choice here).” Patient: “Wow that’s surprising! I’ve cut out a LOT of bad foods from my diet and I’m eating “healthier” like you told me to.” Physician: "Yes, well it doesn’t seem to be working. Here’s a prescription. Get it filled and start taking it.” Patient: “Ok…” This dialogue implies that the patient will be on this drug for the rest of his/her life. That’s where the part of the conversation that’s missing should pick up. Physicians should be explaining that drugs in general are...

As I was about one-third of my way through writing about this study, I realized that I was biased. My understanding of the literature surrounding fructose has led me to conclude that most studies showing detrimental effects are not applicable to the general population (let alone a healthy population) because of methodical limitations such as using fructose in isolation, using doses well above reasonable consumption levels, and using rodents that have known differences from humans in fructose metabolism (e.g., the fact that de novo lipogenesis under conditions of long-term, high-carbohydrate feeding accounts for 60% to 70% of fatty acids in rodents but less than 5% in humans). I therefore deleted everything I had and replaced it with what you are now reading. My goal this time around is to be more objective. As such, I apologize in advance to those of you who find my focus on the nitty-gritty annoying, but...

Among clinical trials investigating long-term weight loss, exercise as the only intervention is virtually useless. When total daily energy expenditure among industrialized societies is compared to contemporary hunter-gatherer tribesmen, they are similar despite the hunter-gatherers performing markedly more physical activity. The risk of dying is reduced dramatically as time spent being active each day increases towards 1 hour, after which it somewhat flat-lines (no additional benefit). Why? Shouldn’t being more active increase energy expenditure? According to the additive energy expenditure model, it certainly should (figure 1). However, as Pontzer et al show in their latest publication, the relationship between physical activity and energy expenditure is far more complex. They provide support for the constrained total energy expenditure model in which energy allocation among physiological tasks responds dynamically to long-term shifts in physical activity. As such, daily energy expenditure is maintained within a relatively narrow range. Five populations hold the answer In...

Three weeks ago I wrote about a study comparing a whey-based ready-to-use therapeutic food (RUTF) to a soy-based RUTF in the treatment of moderate malnutrition. The results showed a clear advantage to the whey-based RUTF, with a significantly greater 3.4% recovery rate, despite a markedly lower amount of calories (-8%) and protein (-33%). What’s more, this study showed that this superior product was similarly affordable, costing a mere $1.36 more per child who recovers from malnutrition. Not everyone agrees that this price is affordable. In a recent study by Bahwere et al, it was argued that “the high milk content of this formulation makes it very expensive for sustainable use in resource-poor settings and increases the proportion of ingredients that have to be imported into developing countries.” Accordingly, they conducted a study comparing the efficacy of a RUTF made from soy, maize, and sorghum (SMS-RUTF) to the efficacy of a peanut...

How would you define “junk food?” I have spent a bit of time pondering this question and my best definition is a highly palatable food high in salt, sugar, and/or fat. Clearly this doesn’t cover everything, but I would argue it encompasses most things people agree shouldn’t be dietary staples. Given my definition above, I was both surprised and joyful that Bolhuis et al from Deakin University recently published a study investigating what impact fat and salt, alone and in combination, have on appetite, food and energy intake, and food palatability. In a randomized crossover design, 48 healthy adults (16 men) completed 4 experimental trials in which they consumed a standardized breakfast followed by an all-you-can-eat lunch. The lunch consisted of elbow macaroni and tomato sauce made with 100% tomato passata (low-fat; LF) or 60% tomato passata, 30% canola oil, and 10% heavy cream (high-fat; HF). The sauce had no added...

Since their recognition as part of some plant foods like soy and flax seeds phytoestrogens have been called into question for their potential to mimic the effects of real estrogens. Phytoestrogens in plants are known as isoflavones. In some cases this is a critical question. Take for instance a woman who is on estrogen blockade therapy for an estrogen dependent breast cancer. Estrogen can stimulate the progression of this and other forms of cancer and as such ridding the body of all estrogen is key to survival. Food manufacturers have said that phytoestrogens don’t convey the same biological effects as real estrogen citing a weaker affinity to the estrogen receptor and strength of estrogenicity. But then industry funded research shows that these isoflavones may protect against osteoporosis, menopausal symptoms, diabetes and obesity.. Hmmm just like real estrogen replacement therapy.  Let’s face it, they don’t want women to stop drinking soy milk!...
