I think a lot of whether food is healthy or less healthy also has to do with
- how was it grown (organic, degree of pesticides, etc)
- how is the food prepared (creation of trans fats, risk of burning, acrylamide, etc)
See these extracts for some things you might want to look into further
Just be aware that there are powerful forces funding propaganda and “research” trying to say it is not that bad.
Personally I don’t know how bad these things are - but seems better to be on the safe side
Fried foods may contain harmful acrylamide
Acrylamide is a toxic substance that can form in foods during high temperature cooking such as frying, roasting, or baking.
It is formed by a chemical reaction between sugars and an amino acid called asparagine.
Starchy foods such as fried potato products and baked goods typically have higher concentrations of acrylamide (22Trusted Source).
Fried foods are typically high in trans fats
Trans fats form when unsaturated fats undergo a process called hydrogenation.
Food manufacturers often hydrogenate fats using high pressure and hydrogen gas to increase their shelf life and stability, but hydrogenation also occurs when oils are heated to very high temperatures during cooking.
The process changes the chemical structure of fats, making them difficult for your body to break down, which can ultimately lead to negative health effects.
In fact, trans fats are associated with an increased risk of many health conditions, including heart disease, cancer, diabetes, and obesity (6Trusted Source, 7Trusted Source, 8Trusted Source).
Since fried foods are cooked in oil at extremely high temperatures, they are likely to contain trans fats.
What’s more, fried foods are often cooked in processed vegetable or seed oils, which may contain trans fats before heating.
When these oils are heated to high temperatures, such as during frying, their trans fat content can increase (9Trusted Source).
In fact, one study found that each time an oil is reused for frying, its trans fat content increases (10Trusted Source).
