Yes on the exercise, but I'd argue that most athletes pretty much have to consume low-quality, high-calorie food in order to keep up to their caloric needs.
Basically, you can't consume 10,000 calories of healthy food... too much volume, even if you spread that out through the entire day.
So in that sense, the power of exercise is pretty amazing, if it can combat the effects of a poor diet for all those years. Then again, if they are consuming a healthy diet when they are not actively competing/training (i.e. on their off days), they're probably undoing a lot of damage just from that.
There's no such thing as a "healthy food" or "unhealthy food" in absolute terms. It's all dependent on the totality of your diet and everything else going on in your life. You don't use an excavator to clear the table after dinner in your fifth floor apartment because that comes with a whole host of problems, but you would use one to move multiple tons of gravel across a construction site. Saying that exercise combats the effects of a poor diet in this context is like saying that working on a construction site negates the negative effects of using an excavator.
Sure there is.
You can measure damage causes by eating unhealthy food, often within hours of their consumption.
Inflammatory response, release of certain chemicals in the body, blood flow, etc.
And the opposite it true when you put healthy food into your body.
You can't outrun a chronically poor diet, especially if its a paleo diet, but it seems like athletes can get away with eating junk food.
Examples? None of the things you've listed are inherently bad effects. It all depends on the magnitude, duration/timing, and probably a bunch of other factors, and any negative needs too be weighed against the benefits of consuming that food.
With my limited time, here are a few:
Magnitude and Timing of the Postprandial Inflammatory Response to a High-Fat Meal in Healthy Adults: A Systematic Review
The effect of high-protein diets on coronary blood flow
Higher ultra-processed food intake is associated with higher DNA damage in healthy adolescents
A single high-fat meal provokes pathological erythrocyte remodeling and increases myeloperoxidase levels: implications for acute coronary syndrome
There are countless other studies showing both positive and negative effects of food after consumption in both the short and long term.
Yes, there are healthy immune responses and damaging ones; healthy chemical release in the body, and damaging ones; good blood flow and harmful blood flow, etc.
Because diet is often not a one-and-done deal, most of the population is putting themselves in a chronic state of harm with every meal and snack.
For an athlete, they choose these foods only because they offer higher calories. Some can tolerate pure carbohydrates in the form of gels and liquids, but those can cause stomach upset. So, eating 20 pancakes drenched in syrup is a "perfect" meal for an ultra-distance runner, while it would be absolutely terrible for a non-athlete.
With food and diet, there is always nuance when it comes to risk/benefit. If athletes ate the way they do when they are training or actively competing as a regular thing, they'd live 10 years less! LOL
I get the impression that we're in agreement but just arguing semantics here. Instead of categorizing food as either healthy or unhealthy, we should be asking what food to eat in order to achieve a given goal with your life circumstances. And not everyone has the same goal or life. Saying that something is healthy/unhealthy in absolute terms implies that it's always/never a good idea to consume them, regardless of your situation.
There's merit in using the terms "healthy" and "unhealthy" from a public health perspective when you're giving broad nutrition advice that applies to the majority of people, but that's not what's happening here. We're specifically talking about athletes.
