Quote: "Deep fried food is one of the worst thing you can eat. It hugely increases your inflammation levels, LDL cholesterol levels. blood pressure and amounts of trans fats and free radicals in the blood. If you want to know why the NHS is on it's backside then look no further than our diet. We're literally poisoning ourselves and our kids with the fried food and sugar we eat.'"
IF you eat too much of it, eating too much of almost anything will harm you, having a KFC isn't in itself harmful and can be eaten perfectly fine with no ill effects and as part of a healthy diet, so long as you don't continually eat it all the time and manage the amount of food/calorie you consume which balancing what you eat in terms of what we already know helps with a healthy lifestyle.
In a commercial operation when it comes to deep frying you'd want to lose as much of the oil from the product as possible in any case.
As an example a mighty buclet for one has 1275 cals, I've never had one but that is just over half my basal calorie intake as a reasonably athletic 15.5 stone male. Would I probably eat all of that if I've eaten during the day too, probably not, if I hadn't eaten all day or had a breakfast only I wouldn't feel any problems with having it as a one off.
Does it contain high amounts of fat, yup, will the calories kill me, no it won't, as I said the KFC or pretty much anything in isolation won't harm you it's when it's taken far too regularly and the same types of food eaten regularly and thus too much calories without balance.
