Diet, RCTs, and the Religion-izing of Science: Even Good Tools Can Be Used Badly

I won a debate this past week. I was pleased to win- despite a crowd mostly hostile to my position at the start, and frequent shifts by my opponent from both reason and the stipulated resolution to derisive innuendo and outright aspersions hurled at my character- because the ostensible topic, food and health, is of enormous importance. That topic is more than ample reason in its own right to weather the slings and arrows of iniquitous confrontation, and take one for the team. How we eat has implications for countless years in countless lives, countless life in countless years, and the fate of the planet.


Protein: Everything You Think You Know is Wrong

Sequential, societal trends in which first dietary fat and then dietary carbohydrate were vilified during recent decades have left dietary protein under an implied halo. The resulting infatuation is naïve, over-simplified, misguided, and misleading. Other than that- it’s perfect.


On and Beyond The Ethics of Eating Animals

My intent, as advertised, is to reflect on the ethics of animals, including our own variety, eating other animals. My further intent is to ruminate on the practical ramifications of the pertinent choices we make as the planet’s supreme apex omnivore, which I will argue reside substantially beyond the dominion of ethics altogether.


LIVE and Let DIEt: Taking Stock of the Ketogenic Kalamity

There is always some popular diet du jour; that, it seems, is how we roll. Atkins; The Zone; South Beach; Sonoma…and so on. No matter how many times weight loss pixie dust has been sprinkled on us before, only to fail, it remains a seller’s market. And somehow, we seem forever inclined to tell ourselves: THIS popular diet is different; this is the ONE.


Breast Cancer Screening: of Chances, and Choices

A sardonic insight by Bertrand Russell deftly, if disturbingly, conveys much of what is wrong in the realm of modern health promotion, particularly where diet is concerned: “The whole problem with the world is that fools and fanatics are always so certain of themselves, and wiser people so full of doubts.” Ordinarily, I would follow the ramifications of that observation for nutrition to all the dubious places they take us, as I have before. But today, I am on a different mission; today’s topic is breast cancer screening.
