The Romans wanted cruel leaders. That hasn't changed. Europeans still want cruel leaders, the crueller the better. Only some layering has changed. They want sophisticated cruel leaders who cleverly hide their sadism. No more blood and skulls and fire. The idea is to make someone suffer as badly as if they had full-body burns, without physically touching them. Ideally, make them think it was their own fault. Or perhaps make them think it's actually a good thing and their suffering is appearing from nowhere. (E.g. welfare.)
Making the populace healthy isn't cruel.
If the food pyramid were some kind of isolated event, perhaps mere public choice theory would explain it. Instead the populace will fight you if you try to debunk the food pyramid, and that goes for everything. It's all cruel lies and sadistic falsehoods, and it's exactly what they demand.
Any form of health-supporting sovereign would suffer immediate and overwhelming violent insurrection.
