Why isn't there a fight against unhealthy food like is for drugs?

[The Grand Nudger]

I try and eat as healthy as I can but I've been told that even when I buy veg from the shops now it doesn't have as much nutrician in as it should because of how they farm veg these days.

LOL... Yeah - that sounds like non-scientific horse-sh*t. Who told you that? Some hippy, trying to sell you some "organic" nonsense? How do "they" farm veg these days, that makes it different from the same varieties of plants cultivated in "ye olden times"?

That ones actually true, but it's partially offset by the fact that we have access to more food.  The average american has greater access to nutrition, but only because the average american consumes an inordinately larger amount of food by mass.  Veggies as grown and marketed are, effectively, water balloons.  They're sold by weight, the weight is water, and the producer wants them in-space and out-of-space asap...so the hormones and cultural practices applied mostly serve the purpose of increasing the speed and uptake of held weight-in-water of any given piece of produce, necessarily diluting it's nutritional density while simultaneously increasing it's market value.  Additionally, ripe produce is not as transportable and gives the middlemen and points of sale less time to "sell it or smell it". So what we have on the shelves, are less-than ripe water baloons. Tomatoes, for example, are picked stone green for transport at the height of their mass before they ripen and become susceptible to disease and rot and pests, and then gassed red for sale. They taste like watery shit because, at that point in their life, there just isn't much else to them.

Plus the countless other ways farms and supermarkets save money and increase produce.

Again - what are those ways and how do they cause obesity? I'm not saying it's impossible - I'm just saying you're providing no evidence, just hear-say and old wives' tales. Just like most people do, when they talk about nutrition.

People like simple answers, even if they're unconfirmed, or just plain wrong. There's a lot more to the way our bodies manage fat, than what you are suggesting - like the amount of sleep we get, the frequency of meals, hormones and more. Fight against "unhealthy foods" is essentially fight against windmills.

This one could be true as well, depending on what Paul is trying to say.  In addition to the above, supermarkets have massive incentives to stock their shelves with non-perishable processed goods.   Producers have massive incentives to peddle those products, since they represent the majority of produced mass on-farm. The actual produce is only a small portion of the plant, and the produce good enough to make it to produce shelves a vanishingly small percentage of that. The rest has to be marketable, or else the producer couldn't afford to (or shouldn't..even if they could) produce that product. Supermarkets stock their shelves with unhealthy shit because it tastes good, sure..but also because it's cheaper for them to stock their shelves with that. They;d rather sell you canned sauce than a ripe tomato....and they know you'll buy it, so that's what they do.
