As some in the food industry, what you posted is right.
However, drinks like Monster and Star are on the rise. Smaller portions, but much higher loads of sugar.
And honestly, when one of the biggest health concerns we have for poor people is them getting to fat, we are among the wealthiest in all of history. I want a banner that hangs in the UN stating that “We made the world’s poor FAT!”
It has nothing to do with wealth - at least not theirs. It's our/my wealth that they pig out on.
