Nutrient density – just what exactly does it mean? In the first part of this two-part series, I took at look at Dr. Fuhrmann’s and Mat Lalonde’s work on nutrient density. In short – Dr. Fuhrmann based his calculation on “Nutrients per Calorie”, and his nutrient-selection for this analysis was suspect at best. Mat Lalonde stuck to known essential nutrients, and his formula included a rigorous statistical analysis, but basically worked out to “Essential Nutrients per Unit Mass”. Overall, I agreed with Lalonde’s approach for the most part, while Fuhrmann’s work seemed biased towards vegetables on purpose, and ignored the valuable contributions from animal foods.
That said, I think Fuhrmann’s analysis does illustrate that there are indeed foods that provide a lot of nutrients while providing little to no calories, Continue reading Nutrient Density Part 2 – My Take on Nutrient Density
Nutrient density – that’s a term I used fairly frequently, but took for granted for a long time. I hadn’t really thought about exactly what it meant until the past few months. First – a story:
A few months back I was out with some friends that I met with regularly (ulti fris team!), and the topic of food and nutrition had been coming up. Within the group was a vegan, who was notably very respectful and not too vocal about being vegan, but after ordering food it was obvious, and some questions were asked. It was all well and good, until the subject of protein was broached, and someone mentioned that you can eat broccoli for protein as a vegan/vegetarian, and that the amount of protein you get is similar to beef. As a nutrition junkie, that sounded like pure garbage to me, so I simply disagreed that broccoli was a good source of protein, while she insisted it was. I let it go because I wanted things to be friendly and I knew I was right, but I did leave that situation wondering where in heavens that otherwise smart person got that idea, so I Googled it up.
Turns out, as some of you may already know, there’s a man named Dr. Fuhrman who published that precious little broccoli-beats-beef tidbit. Continue reading Nutrient Density Part 1 – A Look at Two Models
