Yes, although it's globalizing a pretty big problem. What you said is absolutely true in countries that are adopting a more modern western diet (eg. those upping their intake of processed foods, more meat, tobacco/alcohol, etc. + a bunch of factors around things like AIDS, malaria, diarrhoea, etc. not killing them before those things have a chance to do so which all usually take much longer.

If we're talking about many countries in sub saharan Africa for instance though, I'd say shortage is still a problem and probably going to get worse with climate change since Africa is particularly vulnerable (literally read an article about this yesterday but can't find the link right now)
