I disagree. The writer picks bits and pieces that support the argument offered and not the broad expanse of what what people ate before grain farming and etc.

Did they eat like this before crop farming and animal domestication? Is there any evidence that their lifespan was increased or they didn't have people ill from lactose intolerance?
We can not exactly replicate what our paleolithic ancestors ate but we can get quite close, if we want to and can afford it. Think about it, we evolved to eat a huge variety of meats, bugs, fish, plants, nuts and fruit as they became available in our territory. I suspect it is this variation that adapted us to require a lot of different nutrients, vitamins and minerals.
Stating that we each require an individual diet is just nonsensical when looking at keeping our species going. We are adapted to getting nutrition from what's available, not any specific genus of plants or type of meat. Imagine how long our ancestors would have lasted if they'd said "I can only eat caviar and drink water from the Irrawady."
Why use a sledge hammer to crack a nut when a steam roller is even more effective, and, is fun to drive.
