For some reason though, if I put those two things together and suggest people eat healthier during this pandemic, it's this incredibly controversial thing to say, at least where I live in the US.
But just trying to explain this phenomenon to people is often met with extreme defensiveness. You'll hear: I could NEVER give up pasta/meat/whatever. But they absolutely could, and it wouldn't be nearly as hard as they're imagining.
I'll always encourage anyone curious about tweaking their diet to just go for it, but I've given up entirely on trying to nudge people toward a healthier lifestyle if it's not something they're already working toward.
In Netherlands in loads of restaurant the vegetarian option will taste terrible. In recent years that's slowly changing. I often wondered why someone chose the vegetarian option, it looked and tasted terrible. It wasn't just the initial impression, everything vegetarian was bad to terrible. Plus stupidity on my part, instead of buying something nice that's vegetarian I'd try terrible meat-replacements.
To me someone eating vegetarian was someone giving up enjoying food.
IMO it's nicer to focus on the positives rather than on what someone cannot or should not do. E.g. various colleagues are now vegan. Some just because the vegan diet is better for them (more energy, sleeping, etc). That's stuff they experienced, I'm not vegan/vegetarian.
Another thing I realized is that sometimes the meat part in a dish is actually terrible. A lot of the chicken in Netherlands is sold with a huge amount of added water. It actually does not taste any good, sometimes it is not even noticeable that it is in a dish. A vegan friend was visiting, I already was doubting why I was adding chicken to a dish. Replacing the chicken resulted in a nicer dish (cauliflower with mango chutney plus loads of other spices). Since that experience that dish will at least be vegetarian.
Further, why not let people experience it? Instead of saying that they'll change, maybe say it might happen. IMO it's not that important someone completely changes their diet or never eats something. If they go from regularly eating meat to sometimes eating meat that's already a huge change.
Spend a few weeks not eating anything with refined sugar and suddenly things you used to like are cloyingly sweet. Eat a diet free from all fried foods and you'll find french fries are now too greasy. Etc.
stemming from this, I think the most important thing is that people "get fit" for the right reasons. that they want to have better health, be able to do more activites, etc. vs some of the more usually toxic reasons like trying to meet conventional beauty standards, hating their own appearance. far too often I have seen people who "rush" trying to get fit, or do it for the wrong reasons, and just set themselves up for failure in the long run - or potentially much worse, like depression and the like.
so I think things like having a good measure of "self love" and self worth no matter what you look like, patience, consistency, etc. are all keys to succeeding over just "eating less" or whatever
That may seem illogical since you can't have freedom if you're dead, but we ask people to make a similar trade-off (risk life/health for freedom) when joining the military, and many do.
I'm generally sceptical of tying this kind of advice to crises anyway. It's a social and long-term issue. We ought to eat better not just so that we are better prepared for a pandemic but because it's the right thing to do in general.
Think about universal healthcare and alcohol. How much money is spent on alcohol related issues? The best answer is to ban its sale. Same for tobacco. Enough people have shown then are unable or unwilling to do the right thing. As a result junk food, booze and smokes need to go the way of freedom of speech. We need to ban them.
I think there is more counter evidence then supporting evidence for authoritarian governments being necessary for dealing with pandemics.
1. Please note - comparatively well, Canada, Europe & Oceania aren't doing perfect they're just doing significantly better than the states.
UK, Sweden, Italy, Spain, and Belgium all have had more COVID-19 deaths per capita than the US. And France has a rate nearly equal to the US.
UK, Sweden, Italy, Spain, Belgium, France, and Netherlands all have worse case fatality rates than the US. And so does Canada. (But, this may be because the US has done more testing.)

Also keep in mind Europe was struck before the US - the worst of the first wave is behind them while the US is still riding it down
All that said - Canada is still a country that identifies as a country. If anything is causing a real divide in America it's the entirely manufactured hatred of modern divisive politics. As someone who grew up in Boston I went to school with a wide array of skin tones and original nationalities - there weren't Irish and Italian gangs beating up the black kids - there were suburban entitled white-kid gangs beating up the black kids... Any sort of origin based racism left in America is from more recent immigrants - it's totally bullshit and needs to stop - but I've never met anyone in America that said "Hey - you look Prussian - I don't like Prussians since they moved in on my Pomeranian ancestors. I don't take kindly to you folk."
I am uncertain where you've observed it, but I certainly never saw it in either New England nor the south west.
1. That isn't to say they're leaving tomorrow, there is just actually a serious portion of the population unlike all of the US states.
You don't have to ban things not be authoritarian. Smart governments just price in externalities, which is why you slap tobacco and alcohol with extra taxes to offset the increased costs of health care and reduced adult lifetimes.
What we need is to ban cooking at home. Government soup kitchens. All consumption needs to be documented and controlled.
This needs citation, seriously. Cooking at home, even cooking "insanely unhealthy" butter injected baked chicken at home, still seems to be a lot healthier for you than a hungry man dinner, so I think that the real issue is related to the preservatives and the salt & sugar required to mask those preservatives - that are used to unnaturally extend the self-life of pre-made and frozen food.
Now, if only the government was not as corrupt as it is in Mexico...
I sincerely hope there is someone there to stand for you.
