For those of you who aren't familiar with him, Dr. John McDougall is a doctor and diet/health advocate who recommends a very low fat, high starch, whole food vegan diet to control weight and avoid chronic disease.  He's been at it for a long time, and he's a major figure in the "plant-based diet" community (i.e., a diet including little or no animal foods). Dr. McDougall invited me to participate in his 3-day Advanced Study Weekend retreat in Santa Rosa, CA.  My job was to give my talk on insulin and obesity, and participate in a panel discussion/debate with Dr. McDougall in which we sorted through issues related to low-carb, Paleo, and the health implications of eating animal foods.  I was glad to receive the invitation, because I don't see myself as a diet partisan, and I believe that my evidence-based information is applicable to a variety of diet styles.  I saw the Weekend as an opportunity to extend my thoughts to a new community, challenge myself, and m...

As we continue to explore the foods our ancestors relied on during our evolutionary history, and what foods work best for us today, we come to legumes such as beans and lentils.  These are controversial foods within the Paleolithic diet community, while the broader nutrition community tends to view legumes as healthy. Beans and lentils have a lot going for them.  They're one of the few foods that are simultaneously rich in protein and fiber, making them highly satiating and potentially good for the critters in our colon.  They're also relatively nutritious, delivering a hefty dose of vitamins and minerals.  The minerals are partially bound by the anti-nutrient phytic acid, but simply soaking and cooking beans and lentils typically degrades 30-70 percent of it, making the minerals more available for absorption ( Food Phytates . Reddy and Sathe. 2002).  Omitting the soaking step greatly reduces the degradation of phytic acid ( Food Phytates . Reddy and Sathe. 2002). The only tang...

I recently read an interesting review paper by Dr. Edmund T. Rolls titled "Taste, olfactory and food texture reward processing in the brain and the control of appetite" that I'll discuss in this post ( 1 ).  Dr. Rolls is a prolific neuroscience researcher at Oxford who focuses on "the brain mechanisms of perception, memory, emotion and feeding, and thus of perceptual, memory, emotional and appetite disorders."  His website is here . The first half of the paper is technical and discusses some of Dr. Rolls' findings on how specific brain areas process sensory and reward information, and how individual neurons can integrate multiple sensory signals during this process.  I recommend reading it if you have the background and interest, but I'm not going to cover it here.  The second half of the paper is an attempt to explain the obesity epidemic based on what he knows about the brain and other aspects of human biology.

Warning -- Satire -- April Fool's Post Every child loves animal crackers, those sweet and crunchy animal-shaped biscuits.  But are they compatible with a Paleo diet?  Some people might think they already know the answer, but consider this: our ancestors evolved on the African savanna, eating the plants and animals found there.  Inside each box of animal crackers is an assortment of tiny savanna creatures such as giraffes and elephants. To get to the bottom of this, I interviewed Robert Pearson, CEO of Animal Cracker Products Inc., who explained to me how these crackers are made. Read more »
