"Being careful" on a plant-based diet? Graphs about adequacy/risk of plant-based & animal-based diets

I've uploaded six powerpoint slides from Dr. Kelly's presentation (with his kind permission).
They're available for download here,­ from the Files page of this Meetup site.

The idea here is that the view of plant-based diet has shifted over time:

-a plant-based diet used to be viewed as a diet that carried significant additional risk of nutritional deficiencies, in contrast with animal-based diets that were thought to be a more optimal dietary pattern.

-this thinking has shifted, so that today plant-based diets are still perceived as carrying additional risk of deficiency, but now animal-based diets are also perceived as having similar risks but of "nutritional excess." In other words, people eating a plant-based diet need to "be careful" no more, no less than people eating an animal-based diet.

-the third slide shows a more accurate model depicting the fact that the risk of excess with an animal-based diet is greater than the risk of deficiency with a plant-based diet, thereby putting a greater proportion of animal-based-diet-eaters at health risk than plant-based-diet-eaters.

-the fourth slide shows a proposed hypothesis of dietary adequacy: not only has the risk of excess been understated until now, but the risk of deficiency has been overstated. As evidence mounts of the protective characteristics of plant-based diet, it will come to be viewed as typifying the optimal diet, whereas "you will need to be more careful" if you eat an animal-based diet.

You can read the original article by Joan Sabaté here:­
