You can buy a lot fresh food with $50 USD, groceries are still very affordable in TX with only eggs costing more because of bird flu. Meat, Chicken and Pork are available and even with inflation are still close to pre pandemic prices, although you have to look for specials. I buy lamb chops from NZ at Costco for $5.99 a pound and they are absolutely delicious, Aldi sells 1 pound of ground Lamb for $4.99 from NZ. Steak is around $4.99 lb for NY or T-Bone on sale every week and dairy is not expensive either. Consider myself incredibly lucky to have excellent food that is incredibly affordable.
It’s price and Ozempic et al. Disentangling these effects will require more work.

I don't know if the fast food industry can reinvent itself like the tobacco industry seems to have (see vapes and now zyn) but it's going to be much more difficult I think.
