I don't think I agree with this "nobody has time" thing. Most people don't get that excuse, you can usually make time, most people just choose not to. Do you make time to shower and brush your teeth?
I understand that there are food deserts and some people legitimately work multiple jobs and have kids and that fast food or microwavable dinners and generally unhealthy foods are quick and convenient and affordable but cooking your food doesn't take that much time and not drinking soda frequently takes no time.
Also it's not like veggies and lean meats like chicken are expensive for most people in the US. You can genuinely fill up your basket with lots of leafy greens, veggies, mushrooms and some animal protein for significantly cheaper than with junk food and microwavable dinners, hot pockets, deli meats and cheeses and bread. Unless you live in Alaska maybe.
Not being dismissive of peoples' struggles, a ton of us are being overworked for less money than we're worth, but if you need to you'll make time, you figure it out. Yeah there's sugar in everything processed, cool, you have affordable options that admittedly take a bit of effort to prepare and don't taste as good, but we can eat those and we can eat less. Overeating, constant junk snacking and portion size is also a huge issue in our culture.
