None of the things you mention cover a basic principle of a functioning health system, and that is for people to look after their health. It wouldn't fix the system,
but modern culture is practically guided by mass consumerism. That includes alcohol, junk food, sugars, and unhealthy consumables. Folk are quick to cry 'nanny state' when governments try to intervene, but these voices are stirred up by the very same private companies making a fortune out of this very model of over consumption. They literally profit from our over consumption, all the while finding ways to substitute natural (costly) ingredients with synthertic ones.
There are new worries coming though, and those centre around increasing bowel cancer rates in people under 50 - and these rates
correlate with changing environmental factors (plastics). Remember - correlate doesn't necessarily mean cause - it means need for further study until the burden of proof is statistically overwhelming.
Above all, sedentary lifestyles lead to a decline in health (mental and physical). It's technically easy to increase our activity, but in motivational terms, it's far harder.
