Seaweed has a long history of human consumption that may be true. But so has milk and only part of the adult human population can handle it. We are only at the beginning of understanding how the gut micro-biome relates to human and animal health. Possibilities for complications exist e.g. - Methane production keeps parasites in check - Methane producing bacteria may be part of a synthesis chain for a specific nutrient. - Recalibration of blood health indicator values There are always risks in scaling up things to population levels. The history is full of them. Soylent recently ran into some problems. Gut biology is not an area where things are very predictable.
