It's none of the things you listed but a ton of other things that are mainly found in manufactured food products. Here's a non-exhaustive list:
Natural/artificial flavors - Tricks your body into thinking that food has nutrients it doesn't have, so when your body is low in that nutrient it causes you to crave and overeat that food and you still end up nutrient deficient.
High fructose corn syrup - Fructose causes you to crave more food.
Seed oils - These are less stable than saturated fats. Meaning they're more likely to be oxidized, which is horrible for your health, and they don't act exactly the same as saturated fats. Fats make up your cell walls. Ones built from non-animal fats tend to be less stable and more 'leaky' than animal fat based ones.
Carbs - Eat too many and they spike your blood glucose levels which is bad in multiple ways. Keep it up long term and you end up with diabetes or other cardiovascular issues. Your blood is only supposed to have 4g of glucose in it. Too much or two little is deadly. Your body does a good job of regulating this, because it has to, but when you're constantly snacking and constantly overworking these systems they become less effective and eventually fail.
Fiber - Despite popular media articles, the only good use of fiber is slowing down the digestion of things like carbs. Other than that it's bad for you. It blocks the digestion of what you're eating. You specifically eat things to digest them, so reducing that effectiveness is only good if you're eating things that you shouldn't eat. Fiber can scratch your intestinal walls and it wears out those muscles. Long term, higher fiber intake leads to intestinal issues like diverticulitis. And please, please don't take more fiber if you have constipation. Eat more fat instead if you have to eat something. Fat softens your stool. Fiber tries to hold onto water at the same time as your intestines are trying to absorb that water. Overtime, your intestines win that battle. Fiber also ensures undigested food makes it to your intestines, meaning those food bits haven't be sanitized by your stomach acid. Thus they bring all kinds of bacteria into your gut and start rotting if they move too slowly through it. That's not a good thing. Yes fermentation can make some useful things for you, but you can also simply eat those things instead.
Salt - Only a small portion of the population needs to care about salt. That's probably not you. Interestingly, a lot of headaches can be cured by adding some salt.
Coloring - I don't know much about this topic.
Sweeteners - These cause a variety of issues. Mainly gut issues but they have other effects too. One effect is when your body tastes something sweet it expects to be eating something sugary. Overtime your body learns that and preps the related hormones based on what you're smelling/tasting. Give it zero calorie sweeteners and it gets confused and starts responding incorrectly to sweetness. Sometimes releasing too much or too little hormones. Similar to added flavoring, you'll crave these items more because your body thinks it's getting more energy than it actually is. It notices the imbalance and says 'something's wrong, I should have more energy. Give me more' and you grab the sweetened item which makes the imbalance even worse.
Plants - This is a very wide category. There's two main problems with plants. First, nearly all plants are toxic to humans. There's only a small fraction of them we can safely eat. But even then, most of the ones we can eat simply doesn't kill us quickly. Instead they have compounds that poison us slowly. Our bodies can deal with some levels of that, but go over that amount and it'll cause long term health issues like achy joints. Achy joints aren't a natural aspect of aging. They're a result of slowly building damage your body isn't able to repair (we can include auto-immune issues in this). Part of this poisoning is how we prepare them. Tomatoes are a bit toxic until they ripen. When they're ripening, those toxins are reabsorbed by the rest of the plant. Modern tomatoes are picked before they're ripe and are artificially ripened. This means those toxins are still in the tomatoes you buy in your grocery store and likely in most things made with tomatoes. The extra annoying thing about this is you can have studies showing tomatoes are awesome for you, but the tomato you're eating might not be the same as the tomato in that study. Life is complex. Those complexities matter. Ever see those 'healthy' fruit bars that are basically ground up apples as the base with another fruit for flavoring? You need to digest 150-1000 apple seeds to directly get cyanide posioning. Normally it doesn't matter because seeds go through you. Those fruit bars crush the seeds (and stems) so you're now digesting them. You're not eating 150 seeds, but your body will have to deal with the lower cyanide levels. If that's the only bad thing you ate and you were otherwise perfectly healthy then fine. But that won't be the only bad thing you ate and you're not perfectly healthy. These small things add up over time. Those healthy fruit bars only exist to profit off of waste food products. Those apples and other fruit were too damaged to be displayed in stores or are made from bits cut off from other fruit products. Heat/Preservatives kills anything that would make you sick. Extra rotten food gets pushed into pet food, animal feed, or made into fertilizer. Those fruit bars are ultra-processed foods. If you made them at home you wouldn't grind up the seeds, you wouldn't use near rotten fruit, and you wouldn't need preservatives to keep them safe. The less processed, home made version would be healthier.
Second, different plants have different compounds that reduce the absorption of other nutrients. Eat the wrong things together and you're not getting anywhere close to the nutrition you thought you were getting. Unless you already knew about this, you're probably eating them wrong. As a bonus they're high in fiber and that fiber also reduces the amount of the plant you're digesting thus keeping more of those nutrients from you. That's great if it's sugar, those ant-nutrient components, or the toxins, but bad when it's the nutrients themselves. You don't get to choose, it's all of those things and that's why a ton of studies make fiber look good. The people in those studies have bad diets thus the fiber helps reduce the harms of those bad diets. A better option is to eat a better diet and then you won't need the fiber. You want your digestion to be as efficient as possible.
Preservatives - I don't know a lot about these.
Random stuff - Industrial cleaners, micro plastic, BPAs, BPA replacements, pesticides, etc.. Those things are all bad for you. Most are hormone disruptors, some cause physical damage, others are just toxic. The more a food item gets handled, the more likely it'll pick up some of those things. Animal food has the least of those since animals mainly protect themselves and meat processing is highly regulated (yes curing salts increase risk of cancer by a relative 2-3%). We add those things to protect plants from insects or simply to increase shelf-life. Whole foods need to look perfect in the store, they have to be protected, thus higher levels of those toxic things. The butcher removes any bad meat parts before you see them, thus animals don't need to be perfect. Granted if the animal's feed has higher levels of bad stuff in it then the animal might as well, but it's body filters some out that stuff out just like ours does.
It doesn't help that most people don't understand how the body burns energy. Mainly, you can't out run a bad diet. That's for two reasons. One, running doesn't magically give nutrients you didn't eat (excluding Vit D). Two, your body has a set amount of energy it tries to use each day. When it notices your muscles are constantly using more energy, it reduces the amount of energy from other systems in your body (most noticeable with reproductive and immune systems). Your body is energy greedy. You eat less and it spends less. You eat more and it holds onto more (except when energy intake from protein is less than 9% total energy intake. That causes hormone chances which result in weight loss). CICO holds as it's a law of thermodynamics, but you have far less control over calories out than you realize.
