how is Manitoba Harvest the only brand with such a low fat content?

 

also, you'd figure the 2 unshelled brands would have such similar nutrition facts, not a shelled brand and the unshelled brand. what gives?

 

I guess this begs the larger questions: how and why do different brands that sell the same product have such different nutrition facts? I see the same thing with different other foods too.

There are different strains of hemp with vastly different amounts of protein and fat. Even within certain strains, some batches will be quite different from others. This is true of all foods but most food packaging relies on the USDA nutrition values (in the US that is). The USDA hasn't tested hemp because of the weird legal limbo we have on hemp products here. As a result, these companies are hiring outside firms to do their own testing or just taking the numbers from third party testing they've found.
