People in India are consuming way more of everything, including ghee, than they did three decades ago. Ghee was a luxury then and carefully portioned out. Growing up I ate a lot more Dalda than ghee, simply as a matter of what we could afford. Traditionally ghee was even more of a luxury than in my time. Outside the traditional cowbelt areas, ghee was substantially more expensive relative to other goods prior to Operation Flood. So while Indians have been eating ghee for millennia, they probably ate a tiny fraction of how much we eat it now.
