No mention of nuts in the article, nor in the comments here, which is truly sad. It's like people have forgotten that nuts exist, as they are so often left out the discussion around meat vs plants vs fake meats WRT fats and proteins. Nuts are incredibly nutritious, high in fat and protein that is arguably of better quality than animal fats and proteins, and many nut trees can live for hundreds of years while producing thousands of pounds of nuts every year. Some nut species can live for thousands of years if they are managed correctly (there are still living hazelnuts in Italy that were planted by the Romans). Deeply tap-rooted species like walnuts and hickories don't require supplemental watering once established. I can't find it at the moment but last year I read a study of energy flows for North American tree crops, and the ERoEI of Shagbark Hickory was rated at 55,000.

Going forward, anytime there is discussion of energy or efficiency of plant vs animal agriculture vs fake meat, etc, if tree crops aren't factored into the discussion then that provides an opportunity to quote No Country for Old Men: "You don't know what you're talking about, do you?" Leaving out that there is the option of growing a tree that produces a cow's weight worth of fats and proteins every year, with little to no inputs, in perpetuity, is a crime of omission.

Just to compare some approximate numbers, 100g of hazelnut contains 17.0g of carbs, 13.7g protein, and 60.8g fat. Walnuts contain 9.9g, 26.1g, and 65.2g, respectively. Whereas 100g of beef contains 0g carbs, 35g protein, and 10g fat. And 100 grams of black beans contains 25g carbs, 9g protein, 0.5g fat.
